Your answer is 150.72.

First, plug in the radius and height into the equation. V=1/3pi*4^2*9
Next solve. 3.14 x 16 x 9 = 452.16
Then you need to divide 452.16 by 3 to get 150.72

Answer:

150.72

Step-by-step explanation:

v=1/3 * 3.14 *4² * 9

v=1/3 * 3.14 * 16 * 9

v=1/3 * 50.24 * 9

v=1/3 * 452.16

A rectangle's length is 4 more than twice its width. Its

Complete the work to find the dimensions of the
rectangle.
w(2w + 4) = 240
2w2 + 4w = 240
2w2 + 4w - 240 = 0
2(w + 12)(w - 10) = 0
What is the width of the rectangle?
2w + 4 A = 240 cm2
What is the length of the rectangle?
w

Answers

Answer:

Step-by-step explanation:

width = w

Length = 2w + 4

Area = 240 sq. cm

length * width = 240

(2w + 4) * w = 240

2w *w + 4*w = 240

2w² + 4w = 240

2w² + 4w -240  = 0

2(w²+2w - 120) = 0

2(w² + 12w - 10w - 10*12)=0

2 (w[w + 12] - 10[w + 12] ) = 0

2 (w + 12) (w-10) = 0

Ignore (w + 12) because measurement wont be in negative value

w - 10 = 0

w = 10

Width = 10 cm

length = 2w + 4 = 2*10 + 4 = 20 + 4

Length = 24 cm

Answer:

Width = 10

Length = 24

The perimeter of the figure is, 25.12 feet

And, the area of the figure is, 50.24 feet²

What is mean by Circle?

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We have to given that;

The radius of the partial circle with center A is,

⇒ 4 feet.

Now,

We know that;

Perimeter of circle = 2πr

Here, r = 4 feet

⇒ Perimeter of circle = 2πr

⇒ Perimeter of circle = 2 × 3.14 × 4

⇒ Perimeter of circle = 25.12 feet

And, Area of circle = πr²

Area of circle = 3.14 × 4²

⇒ Area of circle = 50.24 feet²

Thus, The perimeter of the figure is, 25.12 feet

A scientist wants to find the average mass of fish living in a large pond. So she will use the masses of a sample of fish from the pond to find the average mass.
Answer the questions below.

(a) Which unit(s) could be used for the unit of measurement? Check all that apply.

1.) minutes

2.) kilograms

3.) grams

4.) milligrams

5.) seconds

(b) Which of the procedures below would be the best way to find the average mass?


1.) Pick 2 fish from a shallow region of the pond and weigh each of them.

2.) Pick 42 fish from a shallow region of the pond and estimate their masses.

3.) Randomly pick 2 fish from the entire pond and estimate their masses.

4.) Randomly pick 42 fish from the entire pond and weigh each of them.

Answers

Answer:

A. 2, 3, and 4

B: 4

Step-by-step explanation:

Average mass is defined as, adding masses of all bodies and then divide by number of bodies.

(a). Kilograms, grams and milligrams

(b) Randomly pick 42 fish from the entire pond and weigh each of them.

(a). Since we are interested in the masses of the fish and not the time

so that, only unit of mass is to be considered.

Therefore,  Kilograms, grams and milligrams  are used to find the average mass.

(b). Since,  Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen

Therefore, Randomly pick 42 fish from the entire pond and measure their masses. This will provide a representative sample with no bias.

The answer is 10

Step-by-step explanation: So first we divided 15 by 3 which is 5. Then we times 4 and 5 which is 20. 10+x=20, so x = to 10

Answer:

x = 10

Step-by-step explanation:

4/3 = (x+10)/15

Using cross products

15*4 = 3*(x+10)

60 = 3(x+10)

Divide each side by 3

60/3 = 3/3(x+10)

20 = x+10

Subtract 10 from each side

20-10 = x+10-10

10 = x

Answer:

Step-by-step explanation:

I had this exact question on a test and got it right

The maximum number of large binders she can buy is 5.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

Given that:-

Allison is buying binders for school. Small binders cost $3 each, and large binders cost $5 each. If Allison needs to buy at least 12 binders and has no more than $45 to spend, what is the maximum number of large binders she can buy?

From the given data we can form the equation let n1 and n2 are the numbers of the small and the large binders and Sb and Lb are the cost of each binder.

n₁Sb   +   n₂Lb   =   45  ................................1

n₁   +  n₂    =   12

Now put the value of n₁ in equation 1.

( 12  -  n₂ )3  +  5n₂   =   45

36   -  3n₂    +    5n₂   =  45

2n₂   =   9

n₂     =   4.5

n₂    ≅   5

Therefore the maximum number of large binders she can buy is 5.

Find the solution to the system of equations y=2x+1 y=x^2+2x-15

Answers

Answer:

x = 4 OR x = -4

Step-by-step explanation:

To find the solution, you can set both equations equal to one another:

(1) y=2x+1; (2) y=x^2+2x-15

2x+1 = x^2+2x-15

Then solve for the x-values that make this true.

2x+1 = x^2+2x-15

1 = x^2 - 15

16 = x^2

Last year Bob went through bankruptcy and in order to pay his rent for a couple of months took out loans from a small bank - Avarice Bank - and pledged his french horn as collateral. He was unable to make the first payment on the loan so the bank was getting ready to take the french horn for non-payment. Bob approached the director of the Gilroy Philarmonic International Symphony - Joe - for help - asking him to guarantee payment so he does not lose his french horn. Joe agreed to guarantee the payment - partially because Bob is scheduled as the featured performer at the Classic Polka Festival in Gilroy which Joe manages. Joe called Avarice Bank and said if Bob could not pay, he would, and Avarice accepted his guaranty by phone. Bob played for the Polka Festival (it was very successful), but immediately after, left town and his whereabouts are unknown. Avarice has contacted Joe and indicated they have not collected from Bob and they expect Joe to pay the debt. Joe told Avarice they did not have anything in writing from him (though there are witnesses who heard Joe guarantee payment) and he believes he will not be liable for Bob's debt.
