PLSSSS HELPPP find the surface area and volume of the prism ILL GIVE BRAINLIESTT

Lady bird [3.3K]

Answer: 94 and 60, 96 and 42

Step-by-step explanation:

1. For surface area, you need to find the area the sides and base.

Base: 3*4= 12

Side 1: 4*5= 20

Side 2: 3*5= 15

Multiply each by 2.

12*2= 24

20*2= 40

15*2= 30

Add them up.

30+40+24= 94 is the surface area.

For the volume, you multiply each given number.

3*4*5

length * width * height = volume

60 is the volume.

2. For surface area, you need to find the area the sides and base. This is a triangular prisim so the formula is differrent.

Base: 3*7= 21

Side 1: (area of a triangle is 1/2bh) 3*4= 12 / 2= 6

Side 2: (area of a triangle is 1/2bh) 3*4= 12/2= 6

Side 3 (the back): 4*7= 28

Side 4 (the shaded): 5*7= 35

Add them up. This isn't a rectangular prisim so we aren't multiplying the found areas again, in the triangula rpriism we already found ALL areas.

21+6+6+28+35

= 96 is the surface area.

For the volume, you multiply each given number. You follow for triangles,

1/2 BAH

7*4*3=84

84/2

= 42 is the volume.

There are approximately 40,000 people that live in a city. A sample of 20,000 people from that city are asked and 8,000 live in

Archy [21]

Answer:

16,000 people

Step-by-step explanation:

Let's write a ratio

8,000:20,000

Let's write another ratio

x:40,000

We can write a percent proportion.

$\frac{8,000}{20,000} =\frac{x}{40,000}$

We can see that the relationship between the denominators is multiplied by 2 so that means the relationship between 8,000 and x is x is 2 times greater than 8,000

Let me know if you have any questions.

The product of a number and -7 gives seven times the sum of that number and -40. Find the number

Ymorist [56]

Let the unknown number be x.

x × -7 = 7 (x + -40)

-7x = 7x - 280

-14x = -280

x = 280/14

x = 20

Hope this helps!

Answer:
3x --y -2= 0
Step-by-step explanation:
We have formula Y - y 1 = m ( X --x1) => Y - 10 = 3(X-4)
