Answer:

36 3/4

Step-by-step explanation:

I understand now why it was wrong. I am so very sorry and I fixed the answer

Volume = L•W•H

3 1/2 • 7 • 1 1/2 = 36 3/4

.75 = 3/4

John has a job selling souvenirs on a football stadium. He earns $10 per game plus $0.25 dollars for each souvenir he sells. How

Ahat [919]

Answer:

He needs to sell 100 souvenirs

Step-by-step explanation:

We want to know the number of souveniers John has to sell

Let the number of souveniers he sold at the game be s

At a rate of $0.25 per souvenier, the amount earned on souveniers for s souveniers will be:

$0.25 \times s =0.25s$

Now, if we added this to the amount he earns per game, we will have the total $35 earned for working at one game.

Thus, mathematically:

$0.25s + 10 = 35 \\ 0.25s = 35 - 10 \\ 0.25s = 25 \\ s = \frac{25}{0.25} \\ s = 100$

David is performing the following construction. Based on the markings that are present, what construction is he performing?

lora16 [44]

Answer:

He is bisecting the angle BAC.

Step-by-step explanation:

First he puts the compass point at point A and draws 2 small arcs at D and E. Then he places the compass point at D and then at E to form the 2 arcs that cross between the 2 line segments AB and AC.

The bisector is the line he can draw between A and the crossed arcs.

If the figure is rotated 270° counterclockwise about the origin, what is the length of segment N′P′?

kap26 [50]

Answer:

Option (2)

Step-by-step explanation:

Since, rotation of any figure is a rigid transformation, side lengths and measure of angles of the image polygon after rotation will remain same.

NP = N'P'

Coordinates of N → (5, 9)

Coordinates of P → (7, 9)

Formula of distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is,

d = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

By this formula length of NP = $\sqrt{(7-5)^2+(9-9)^2}$

= 2 units

Therefore, Option (2) will be the correct option.

What is an equivalent to -16m^2n-(-25m^2n)+(-7m^2n)

pantera1 [17]

Answer:

The equivalent expression is:

$-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)=2m^2n$

Step-by-step explanation:

Given the expression

$-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a$

$=-16m^2n+25m^2n-7m^2n$

$\mathrm{Add\:similar\:elements:}\:-16m^2n+25m^2n-7m^2n=2m^2n$

$=2m^2n$

Therefore, the equivalent expression is:

$-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)=2m^2n$
