PLEASE HELP!!!! WILL MARK BRAINLIEST!!!

Mathematics
1 answer:
Aleksandr-060686 [28]3 years ago
6 0

Answer:

The volume of the model is 321\ m^{3}

Step-by-step explanation:

we know that

The volume of the sphere (model of the earth) is equal to

V=\frac{4}{3}\pi r^{3}

In this problem we have

r=8.5/2=4.25\ m ----> the radius is half the diameter

substitute the values

V=\frac{4}{3}(3.14)(4.25)^{3}=321\ m^{3}

Simplify.
djverab [1.8K]
15m + 2n, first you have to pair the matching variables, 8m and 7m along with the sign in front of them. so 8m(+7m), you would then add those then do the same with the other, +4n(postive) and -2n, so subtract 2 from 4 and get 2. put them together and it’s 15m+2

Jessica gets her favorite shade of purple paint by mixing 1/3
strojnjashka [21]

Answer:

8 cups of blue and 12 cups of red

Step-by-step explanation:

Combine 1/3 c of blue + 1/2 c of red = 5/6 c of purple.

(5/6)x = 20

 

x = (6/5)20 = 24

this is applied to each of the above measurements to show that you need 8 c of blue + 12 c of red.

Timmy writes the equation f(x) = 1/4x – 1. He then doubles both of the terms on the right side to create the equation g(x) = 1/2
Lana71 [14]

Remark

The best way to answer something like this is to actually graph both equations. I have done that for you below.

Red Line: f(x) = 1/4x - 1

Blue Line: g(x) = 1/2x - 2

Now look at the answers.

A: The first one is incorrect. You don't need the graph to tell you that. The larger the number in front of the x, the steeper the line. Put another way, the larger the slope, the steeper the line. The y intercept is lower however.

B is wrong. g(x) is steeper, but the y intercept is lower not higher than f(x) [Negatives do strange things].

C:The g(x) is steeper (we've said that a couple of times), and it has a lower y intercept.

D is correct.

E is just wrong. Both parts are incorrect.
