The total length of the string in feet is 6 feet, and the combined capacity of both water jugs in cups is 75 cups.
What is the total length of the string, and how many cups of water can the two water jugs hold altogether?Step 1: To find the total length of the string in inches, Mara needs to add the lengths of the three pieces of string:
30 inches + 22 inches + 20 inches = 72 inches
So the total length of the string in inches is 72 inches.
Step 2: To convert inches to feet, we need to divide the number of inches by 12 (since there are 12 inches in a foot):
72 inches ÷ 12 = 6 feet
Therefore, once Mara puts together the three pieces of string, the total length will be 6 feet.
Step 1: To find out how many ounces of water both water jugs hold altogether, we need to add the capacity of the two jugs:
300 ounces + 300 ounces = 600 ounces
So both water jugs together can hold 600 ounces of water.
Step 2: To convert ounces to cups, we need to divide the number of ounces by 8 (since there are 8 ounces in a cup):
600 ounces ÷ 8 = 75 cups
Therefore, both water jugs together can hold 75 cups of water.

What is the sum of 2 / 10 + 6/100 not simplified
Answer: 26/100 OR 0.26 (I would put the answer as a fraction)
Step-by-step explanation:
We need both fractions to have the same denominator before we add them. The denominator of 6/100 is 100. The denominator of 2/10 is 10. We need to turn 10 into 100. To do that, we can do 10*10. This gives us 100. However what we do to the bottom must be done to the top therefore we have 20/100 + 6/100
Now the two fractions can be added together. 20/100 + 6/100 = 26/100.
Normally we would simplify this down to 13/50 but if you want it unsimplified 26/100 would be your answer.

HELPPPPP PLEASEEEEEE!!!!!!!
To determine how many times a day we would need to fill the container shown below, we need to calculate its capacity in cubic centimeters. Let's assume that the container is a rectangular prism with dimensions of 30 centimeters (length) x 20 centimeters (width) x 25 centimeters (height). The formula for calculating the volume of a rectangular prism is:
Volume = length x width x height
Plugging in the values we have, we get:
Volume = 30 cm x 20 cm x 25 cm
Volume = 15,000 cubic centimeters
Therefore, the container has a capacity of 15,000 cubic centimeters. To determine how many times we would need to fill it each day, we need to divide the amount of pellets and hay we feed the okapi daily (5,024 cubic centimeters) by the capacity of the container (15,000 cubic centimeters):
5,024 / 15,000 = 0.3356
This means that we would need to fill the container approximately 0.3356 times a day, which is not a practical answer. We need to round this up to the nearest whole number.
The options given to us are 80 times, 40 times, 16 times, and 4 times. Out of these options, the closest whole number to 0.3356 is 1, which means we would need to fill the container once a day.
Therefore, the answer is that we would need to fill the container shown below 1 time a day to feed the okapi their daily amount of pellets and hay.

A motorboat is headed due east, directly across a river at 5 m/s. the current of the river is 2 m/s downstream (due south). find the following: a) the resulting true speed of the boat; b) the compass direction of the boat; and c) the distance downstream the boat will land on the shore if the river is 800 meters wide.
a) The resulting true speed of the boat is approximately 5.39 m/s.
b) The compass direction of the boat is 21.8° south of east.
c) The distance downstream the boat will land on the shore if the river is 800 meters wide is 320 meters.
a) To find the true speed of the boat, we can use the Pythagorean theorem. Since the boat's speed is 5 m/s due east and the current's speed is 2 m/s due south, we can treat these as perpendicular vectors. The true speed can be found using the formula:
True Speed = √((5 m/s)² + (2 m/s)²) = √(25 + 4) = √29 ≈ 5.39 m/s
b) To find the compass direction of the boat, we can use the inverse tangent function. The angle θ can be calculated using:
θ = arctan(opposite/adjacent) = arctan(2 m/s / 5 m/s) ≈ 21.8°
Since the boat is headed east and the current is pushing it south, the true direction is 21.8° south of east.
c) To find the distance downstream where the boat will land, we first need to calculate the time it takes to cross the river. The boat's speed across the river (due east) is 5 m/s and the width of the river is 800 meters. The time taken to cross the river is:
Time = Distance / Speed = 800 m / 5 m/s = 160 seconds
Now, we can use the time to find the distance downstream by multiplying the current's speed (2 m/s) by the time:
Distance downstream = 2 m/s × 160 s = 320 meters
So, the boat will land 320 meters downstream from its starting point on the opposite shore.

I need help what is the approximate area, in square feet, of the shaded region in this figure use 3. 14
To find the approximate area of the shaded region in this figure, we need to subtract the area of the smaller circle from the area of the larger circle. The radius of the larger circle is 6 feet and the radius of the smaller circle is 3 feet.
The formula for the area of a circle is A = πr^2, where π is approximately 3.14 and r is the radius.
So, the area of the larger circle is A = 3.14 x 6^2 = 113.04 square feet.
The area of the smaller circle is A = 3.14 x 3^2 = 28.26 square feet.
To find the area of the shaded region, we subtract the area of the smaller circle from the area of the larger circle:
Area of shaded region = 113.04 - 28.26 = 84.78 square feet (rounded to two decimal places).

C. Yes; the graph passes the vertical line test.
How does the graph below represent a function?The correct answer is C. Yes; the graph passes the vertical line test.
To determine whether a graph represents a function, we apply the vertical line test. The vertical line test states that for a graph to represent a function, no vertical line should intersect the graph in more than one point.
In this case, the graph passes the vertical line test if each vertical line crosses the graph at most once. If this condition is satisfied, then each x-value corresponds to a unique y-value, indicating that the graph represents a function.

Given that abcd is a rhombus, determine the length of each diagonal, ac, and bd if m∠ade=20° and ad = 8cm. please help and show me how you did it
The length of diagonal ac is approximately 15.58 cm, and the length of diagonal bd is approximately 12.22 cm
Rhombus is a special type of parallelogram in which all four sides are congruent. The opposite angles of a rhombus are also congruent, and the diagonals bisect each other at right angles.
Now, let's consider the given rhombus abcd, where ad = 8cm and m∠ade=20°. We need to determine the length of diagonals ac and bd.
First, let's use the law of cosines to find the length of side ae. We know that ad = 8cm, and m∠ade=20°, so we can use the formula:
ae² = ad² + de² - 2ad(de)cos(m∠ade)
Substituting the values, we get:
ae² = 8² + de² - 2(8)(de)cos(20°)
Next, we can use the fact that a rhombus has all sides congruent to find the length of side de. Since abcd is a rhombus, we know that ac and bd are also congruent diagonals that bisect each other at right angles. Therefore, we can draw diagonal ac and use the Pythagorean theorem to find the length of ac:
ac² = (ae/2)² + (de/2)²
Substituting ae² from the previous equation, we get:
ac² = ((8² + de² - 2(8)(de)cos(20°))/4) + (de/2)²
Simplifying the equation and using the fact that ac and bd are congruent, we get:
bd² = ac² = (8² + de² - 2(8)(de)cos(20°))/2
Finally, we can use the Pythagorean theorem to find the length of diagonal bd:
bd² = ab² + ad²
Substituting ab = ac/2 and ad = 8cm, we get:
bd² = (ac/2)² + 8²
Substituting ac² from the previous equation, we get:
bd² = ((8² + de² - 2(8)(de)cos(20°))/8)² + 8²
Simplifying the equation, we get:
bd ≈ 12.22 cm
Similarly, we can solve for ac using the equation we derived earlier:
ac² = ((8² + de² - 2(8)(de)cos(20°))/4) + (de/2)²
Substituting de ≈ 9.84cm (which we can solve for from the equation ae² = 8² + de² - 2ad(de)cos(m∠ade)), we get:
ac ≈ 15.58 cm
Therefore, the length of diagonal ac is approximately 15.58 cm, and the length of diagonal bd is approximately 12.22 cm

The perimeter of Koch's snowflake fractal will be infinite.
Find out how Koch's snowflake fractal is created by adding triangular bumps to the side of an equilateral triangle?Koch's snowflake fractal is created by adding triangular bumps to the sides of an equilateral triangle at progressively smaller scales. At each stage, the number of sides of the resulting figure increases by a factor of 4, and the perimeter of the figure increases as well.
To see how the perimeter changes as bumps are added to all sides of the figure, we can use the fact that each bump adds a segment of length 1/3 to the original side. So if we start with a triangle of side length 1 and add a bump to each side, the new perimeter is:
P = 3(1 + 1/3) = 4
Now we have a figure with 12 sides. If we add a bump to each of these sides, the new perimeter is:
P = 12(1 + 1/3 + 1/9) = 16/3
In the next stage, we have 48 sides, and each side has a length of 1/3^2, so the new perimeter is:
P = 48(1 + 1/3 + 1/9 + 1/27) = 64/3
At each stage, we can see that the perimeter is multiplied by a factor of 4/3. So if we carry on this process forever, the perimeter of Koch's snowflake fractal will be infinite.

Astha had $5,700 in her savings account when Henry opened a savings account with zero dollars.
Astha deposited $100 into her account each week for x weeks.
Henry deposited $75 into his account each week for x weeks.
The accounts did not earn interest.
Which inequality represents this situation when the amount of money in Astha's account was greater than the amount of money in Henry's account?
Answer choices:
100x < 5,700 + 75x
75x > 5,700 + 100x
100x > 5,700 + 75x
75x < 5,700 + 100x
Astha's account was greater than the amount of money in Henry's account is:
5700 + 100x > 75x
Why Astha's account was greater?Let's start by finding the total amount of money deposited by Astha and Henry after x weeks.
Astha deposited $100 into her account each week for x weeks, so the total amount she deposited is 100x.
Similarly, Henry deposited $75 into his account each week for x weeks, so the total amount he deposited is 75x.
To find the inequality that represents the situation when the amount of money in Astha's account was greater than the amount of money in Henry's account, we need to compare the total amount of money each of them deposited.
Astha started with $5,700 and deposited $100 each week for x weeks, so the total amount of money in her account after x weeks is:
5700 + 100x
Henry started with zero dollars and deposited $75 each week for x weeks, so the total amount of money in his account after x weeks is
75x
Therefore, the inequality that represents the situation when the amount of money in Astha's account was greater than the amount of money in Henry's account is:
5700 + 100x > 75x

The figure
If the lines that appear to be tangent are tangent, then we have the following equation
x = 26 - 18
Evaluate the like terms
x = 8
The perimeter is the sum of the side lengths
So, we have
Perimeter = 26 + 18 + 14 + 14 + x
This gives
Perimeter = 26 + 18 + 14 + 14 + 8
Evaluate
Perimeter = 80
Hence, the perimeter is 80 units

The iterative function that describes how your new car loses value over time is f(t)=0. 75t, where t is the number of years since you purchased the car. If you paid $25,000 for your car and you sell it after owning the car for 3 years, how much is the car worth?
t_3=$14,062. 50
t_3=$10,546. 88
t_3=$7,910. 15
t_3=$18,750
If you paid $25,000 for your car and you sell it after owning the car for 3 years, then the worth of the car is t₃=$7,910. 15 (option c).
To find the value of your car after owning it for 3 years, we need to evaluate the function at t=3. This means we need to substitute t=3 into the function and simplify the expression.
f(3) = 0.75(3) = 2.25
The output of the function when t=3 is 2.25. But what does this number mean? It represents the fraction of the original value of the car that remains after owning it for 3 years.
To find the actual value of the car, we need to multiply this fraction by the original value of the car, which is given as $25,000.
Value of car after 3 years = 2.25 x $25,000 = $56,250
Therefore, the value of the car after owning it for 3 years is $7,910.15. This is the option (C) in the given choices.
