Valerie is performing an experiment by spinning a metal weight around on the end of a nylon thread. How far does the metal weight travel if it completes $$40 revolutions on the end of a $$0.89 m thread? Give your answer correct to one decimal place.

Answers

Answer 1

Answer:

35.6 m

Step-by-step explanation:

Number of revolutions = 40

Length of thread = 0.89 m

Total Distance = Number of revolutions * Length of Thread

Total Distance = 40 * 0.89 = 35.6 m

Answer:

  D.  81/m^7

Step-by-step explanation:

The applicable rules of exponents are ...

  (ab)^c = (a^c)(b^c)

  (a^b)^c = a^(bc)

  (a^b)(a^c) = a^(b+c)

  a^-b = 1/a^b

__

Using these, your expression simplifies to ...

  [tex](3m^{-4})^3(3m^5)=(3^3)(3)(m^{-4\cdot3+5})=81m^{-7}=\boxed{\dfrac{81}{m^7}}[/tex]

Explanation:

This tent is a triangular prism. We have two congruent triangles in front and back. Let's stand the triangular prism up so that the triangle forms the base, or floor, of this figure.

The area of the base triangle is 5*4/2 = 20/2 = 10 square feet. I used the formula base*height/2 to get the area of a triangle.

Once we know the area of the base of the prism, we multiply that by the height of the prism, which is the 8 ft. So we get 10*8 = 80 cubic feet of volume.

(a) Whats the area of a rectangular field is 3888 m. If the length of the field is 72 m, what is its width?

(b)The perimeter of a rectangular painting is 374 cm. If the width of the painting is 88cm, what is its length?

Answers

Answer:

part a is 54            part b is 99

Step-by-step explanation:

72 x ? =3888

x=54

374 is the perimeter. You have a side that is 88cm so the opposite side will be 88 cm as well. 374-176=198

so between the last 2 sides we have 198. The sides will be equal so you just divide it by 2  

so the top and bottom of the rectangle are 99 and both sides are 88

Find the slope of the line that passes through (2, 4) and (9, 9).

Answers

Answer:

x = 1 y = -3 (1, -3)

Step-by-step explanation:

Use the Substitution Method

First, you have to turn the equations into slope intercept form (y = mx + b)

First equation

x - y = 4

subtract x from both sides

-y = -x + 4

divide each side by -1

y = x - 4

Second Equation

4x + y = 1

subtract 4x from both sides

y = -4x + 1

Turn the two new equations into one equation like so

-4x + 1 = x - 4

add 4x to both sides

1 = 5x - 4

add 4 to both sides

5 = 5x

divide each side by 5

x = 1

Fill in x in one of the original equations in order to find the value of y

4(1) + y = 1

4 + y = 1

subtract 4 from both sides

y = -3

The solution is (1, -3)

hope this helps :)

it would end up being 4 since it is the biggest number that can divide between 8 and 20.
