What is the exact volume of the sphere?
O 2481.1567 cm
O 7263.397 cm
O 7790.837 cm
O 22807.057 cm

Answer:

v= 262 (3 significant figures)

Step-by-step explanation:

volume of hemisphere= 2/3 * π * r³

v= 2/3 * 22/7* 125

v= 261.799388cm3

v= 262 (3 sf)

Answer:

JK is NOT tangent to the circle

Step-by-step explanation:

A tangent of a circle is a line that intersects a circle at one and only one point. For this reason, the radius will always intersect a tangent at a 90 degree angle to prove this single point intersection. From the triangle, we can introduce the Pythagorean theorem to see if the triangle is a right triangle:

a^2 + b^2 = c^2

48^2 + 14^2 = 36^2

2304 + 196 = 1296

2500 ≠ 1296

As this is not equal, the triangle is not a right triangle and therefore states that the tangent line does not intersect the radius at 90 degrees, meaning that it does not satisfy the requirements of a tangent line.

Step-by-step explanation:

Since The angle sum property of traingke is 180°.

Answer:

No, these lengths will not form a triangle.

Step-by-step explanation:

The Triangle Inequality Theorem states that the sum of two sides must always be greater than the third side.

55 + 76 = 131

131 is not greater than 112.

Therefore, these lengths will not form a triangle.

Answer:

The slope equals the rise divided by the run: . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it.

Answer:

the slope of the line​ is 1

Step-by-step explanation:

The line goes  1 up, 1 right, 1 up 1 right ........

1 divided into 1 = 1

Answer:

D

Step-by-step explanation:

Think about some easy coordinates. If you plug in x=0, the y coordinate must be 2, eliminating B.

Next, as x becomes larger and larger, the y value decreases. This means that the value inside the bracket must be less than 1. If it is greater than 1, the y value would increase as x increased.

To illustrate, 2 < 2^2 < 2^3 < 2^4

However, 0.5 > 0.5^2 > 0.5^3

You can check this in your calculator if you need to.

Hope that helped! :)

Answer:

40%

Step-by-step explanation:

➡6/15×100

➡600/15

➡40%

Answer: 40% of the plants are carrots

Step-by-step explanation:

In order to figure out the percentage, we have to find what "part" of the "total" are the carrots, which is given. We already know that 6 of the total 15 plants are carrots. When referring to a percentage, basically we are trying to find out how many carrots there would be, if we were to have 100 plants. So, in order to do so, we would need 100 plants. I'll make it even more simple:

We have 15 plants - 6 of which are carrots

If we were to have

100 plants         - HOW MANY would be carrots??

The answer to our question is also the percentage we are looking for. If we replace HOW MANY with x, than we would have this equation: 15*x=6*100, so 15x=600 and x=40, so the percentage is 40%.

In order to make this easier, as i said in the beginning we are referring to the part of a total, with given numbers, so if we would divide 6 out of 15, we would have 6/15=0.4 , multiplying that number with 100 (for the percentage), you get 40% again, with a faster and easier way. Practice makes perfect.

Answer:

Stanley needs 31 feet and 2 inches of fencing.

Step-by-step explanation:

In order to answer this problem, you need to find the perimeter of the dog run.

Since: [tex]P=2(l+w)[/tex]

and [tex]l=149[/tex] inches & [tex]w=56[/tex] inches

Plug in what we know :

[tex]P=2(149+56)[/tex]

and solve:

[tex]P=410[/tex] inches

The dog run has a perimeter of 410 inches.

However, now we need to subtract 36 inches since the gate doesn't need fencing.

[tex]410-36=374[/tex] inches.

The dog run needs 374 inches of fencing.

In order to find out how many feet of fencing that is, divide it by 12.

[tex]\frac{374}{12}[/tex] = 31.16666667 OR [tex]31\frac{2}{12}[/tex], meaning 31 feet and 2 inches.

Answer:

31 feet and 2 inches of fencing :))<3

Step-by-step explanation:

Breakeven quantity are the number of  units produced and sold at which net income is zero

Breakeven quantity = fixed cost / price – variable cost per unit

Fixed costs are costs that do not vary with output. e,g, rent, mortgage payments

If production is zero or if production is a million, Mortgage payments do not change - it remains the same no matter the level of output.  

Hourly wage costs and payments for production inputs are variable costs

Variable costs are costs that vary with production

fixed cost = $2450

Variable cost = $75

price = $145

(2450) / (145 - 75) = 35

Answer:

The dependent variable is speed of typing; the independent variables are the keyboard design and the chime.

Step-by-step explanation:

The variable which we intend to measure or determine is called the dependent or predicted variable. However, to predict or measure the dependent variable, one or more variables are required, these are the variables whose different values or input affects the outcome of the dependent variable, these variables are called the independent variable.

In the scenario described above, the dependent variable is typing speed as it is the variable we intend to measure or determine using the new keyboard design and chime as the predictor variables.

Answer:

$667.51

Step-by-step explanation:

610.99 times .0925 is 56.516575. 56.516575 plus 610.99 is 667.506575. That rounded to the nearest cent is 667.51.

Answer:

c and d

Step-by-step explanation:

Simplify a: 6x+7=4x+7 ~ No matter what, this cannot be possible

Simplify b: 6x=4x ~ Once again, this is impossible unless x=0, but I'll assume it can't be for now

Simplify c: 4x+7=4x+7 ~ This clearly is a correct statement, this it is c

Simplify d: 6x-1=4x+1 ~ By subtracting 4x on each side, then adding 1 on both sides, we get 2x=2, so x can be 2.

okay 1 student = 1/20 chance of picking yellow

1/20 (30/30) = 30/600 chance of picking yellow out of 30 studnets

30/600 = 0.05 = 5% chance of choosing yellow.

I each studnet picks 1 yellow marker. Is that all the options?
