Amir can seal a driveway in four hours working together he and Louis conceal it in 2.3 hours how long would it take Louis to seal it working alone
Answer:
Louis can seal the driveway in 5.41 hours.
Step-by-step explanation:
[tex]\frac{1}{4}[/tex] + [tex]\frac{1}{x}[/tex] = [tex]\frac{1}{2.3}[/tex] 4 × 1x × 2.3 = 9.2x
9.2x([tex]\frac{1}{4}[/tex] + [tex]\frac{1}{x}[/tex] = [tex]\frac{1}{2.3}[/tex])
2.3x + 9.2 = 4x
9.2 = 1.7x

The surface area of the yellow surfaces on the wheel pod is 20 square inches
How to determine the surface area?The yellow surfaces on the wheel create a circle with the following parameter:
Diameter, d = 5 inches
The radius (r) is calculated using:
r = d/2
So, we have:
r = 5/2
Evaluate
r = 2.5
The surface area is then calculated using:
A = πr²
So, we have:
A = 3.14 * 2.5²
Evaluate
A = 19.625
Approximate
A = 20
Hence, the surface area of the yellow surfaces on the wheel pod is 20 square inches

What is the equation of a line passing through (5,2) and parallel to the line represented by the equation y= 2x + 1?
Answer:
y= 2x -8
Step-by-step explanation:
To find the equation of a line passing through (5,2) and parallel to the line represented by the equation y= 2x + 1, we will follow the steps below;
since the line is parallel to y=2x + 1, then the will have the same slope. That is; m₁ = m₂
comparing y = 2x + 1 to y = mx + c
m= 2
we will substitute m= 2 x= 5 and y = 2 into y = mx + c and then solve for c
y = mx + c
2 = 2(5) + c
2 = 10 + c
subtract 10 from both-side of the equation
2-10 = 10 -10 + c
-8 = c
c=-8
To find our equation, we will substitute m = 2 and c=-8 into y=mx + c
y = 2x - 8
Therefore, the equation of a line passing through (5,2) and parallel to the line represented by the equation y= 2x + 1 is y= 2x -8

you purchase a cafeteria business for $15,000. you put $2,250 down and finance the rest to pay off the loan in 5 years at 12% true annual interest. what are your monthly payments to pay off the loan ?
Answer: $ 272.49
Step-by-step explanation:
Please see attached formula
The monthly payments to pay off the loan is $1528.3
What is loan?A loan is a form of debt incurred by an individual or other entity. The lender—usually a corporation, financial institution, or government.
Given that, you took a loan, of $15,000, $2,250 down and finance the rest to pay off the loan in 5 years at 12% true annual interest.
Interest will be on = 15000 - 2250 = 12750
Formula to be used :-
PV = PMT / i [1-1/(1+i)ⁿ]
12750 = PMT / 0.12[1-/(1+0.12)⁶⁰]
12750 = PMT / 0.1198
PMT = 1528.29622
Hence, the monthly payments to pay off the loan is $1528.3

68° is looking in front of one line, so the other line's front have to be 68°
now we found 2 corner of triangle.
a triangle's sum of interior angles equal to 180°
68°+68° = 136°.
now i have to remove 136 from 180 to find our x
180°-136° = 44°

a square is inscribed In a circle with radius 6[tex] \sqrt{2} [/tex]
inches. what is the perimeter of the square in inches? help pls
Answer:
48 in
Step-by-step explanation:
The diagonal of the inscribed square equals the diameter of the circle.
1. Calculate the diagonal of the square
d = 2r = 2 × 6√2 in =12√2 in
2. Calculate the side of the square
∆ACB is an isosceles right triangle.
We can use Pythagoras' Theorem to calculate the length of a side s.
[tex]\begin{array}{rcl}s^{2} + s^{2} & = & (12\sqrt{2})^{2}\\2s^{2} & = & 144 \times 2\\s^{2} & = & 144\\s & = & \text{12 in}\\\end{array}[/tex]
3. Calculate the perimeter of the square
P = 4s = 4 × 12 in = 48 in
The perimeter of the square is 48 in.
The perimeter of the square in inches is 48 square inches
The diameter of the circle is twice the given radius
Given the following:
radius = 6√2
diameter = 2(6√2)
diameter = 12√2
The diagonal of the cube inscribed will be equal to the diameter of the circle.
Next is to get the side length "l" of the square using the Pythagoras theorem. According to the theorem:
l²+l² = (12√2)²
2l² = 144(2)
l² = 288/2
Take the square root of both sides
l² = 144
l = √144
l = 12inches
Next is to get the perimeter of the square
Perimeter of the square = 4L
Perimeter of the square = 4(12)
Hence the perimeter of the square is 48 square inches

Determine the possible side lengths of the third side of a triangle with known side lengths of 6 and 12. A) 6 < c < 18 B) –6 < c < –18 C) 12 < c < 6 D) 6 < c < 12
Answer:
A) 6 < c < 18
Step-by-step explanation:
A triangle is known to have 3 sides: Side a, Side b and Side c.
For a triangle, one of the three sides is longer than the other two sides. (The only exception is when we are told specifically that a triangle is an equilateral triangle, where all the 3 sides are equal to each other).
To solve the above question, we would be using the Triangle Inequality Theorem.
The Triangle Inequality Theorem states that the summation or addition of the lengths of any two sides of a triangle is greater than the length of the third side.
Side a + Side b > Side c
Side a + Side c > Side b
Side b + Side c > Side a
For the above question, we have 2 possible side lengths for the third side of the triangle. We are given in the above question,
side (a) = 6
side (b) = 12
Let's represent the third side as c
To solve for the above question,we would be having the following Inequality.
= b - a < c < b + a
= 12 - 6 < c < 12 + 6
= 6 < c < 18
Therefore, the possible side lengths for the triangle is the above question is Option A) 6 < c < 18

HELP ME PLZZZZZZZZZZZZZZZ
Answer:
C
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (4, 2) ← 2 points on the line
m = [tex]\frac{2-0}{4-0}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex] → C
The slope indicates the rate of change.
Thus the water is flowing at [tex]\frac{1}{2}[/tex] gallon per minute

For 4 h, the temperature in Victoria fell by 2°C each hour. What was the total change in temperature?
Answer:
The total change was 8*C
Step-by-step explanation:
If the unit rate is 2/1 ~2 degrees per every 1 hour~ than you would need to multiply 2 by the amount of hours given to get the total change in temperature, which would be 8*C.
What is a dilation and how does this transformation affect a figure in the coordinate plane?
Answer: A dilation is a transformation that produces an image that is the same shape as the original one,but in in different size. A dilation of a figure can make the figure bigger or smaller in the coordinate plane.
Step-by-step explanation:
Answer:
A dilation is a type of transformation in which an image is enlarged or shrunk. This does not change the shape other than the fact that it is bigger or smaller.
Step-by-step explanation:
Think of it this way: When Ant Man grows or shrinks, his hair doesn't change color or he isn't missing an arm or anything. Nothing about his body shape is changed- He is just smaller or bigger. That's essentially how a dilation works. Hope this helped!
Priya’s cat is pregnant with a litter of 5 kittens. Each kitten has a 30% chance of being
chocolate brown. Priya wants to know the probability that at least two of the kittens
will be chocolate brown.
To simulate this, Priya put 3 white cubes and 7 green cubes in a bag. For each trial,
Priya pulled out and returned a cube 5 times. Priya conducted 12 trials.
Answer:
30.87%
Step-by-step explanation:
Priya's simulation is fine, as 30% is represented by the 3 white cubes.
The more times the experiment is carried out, the closer it is to the theoretical probability, which is calculated as follows:
p (n = x) = nCx * p ^ x * q ^ (n-x)
We obtain that p = 0.3 and q = 1-0.3 = 0.7. also n = 5 and x = 2.
replacing we have:
p (5 = 2) = 5C2 * 0.3 ^ 2 * 0.7 ^ (5-2)
p (5 = 2) = 5! / (2! * 3!) * 0.03087
p (5 = 2) = 0.3087
which means that the probability is 30.87%, and the more the experiment is carried out, the closer it is to this probability.
