Answer:

D. 4

Step-by-step explanation:

The faster you go, the faster you get home (theoretically anyway) and vice versa. So if your speed is doubled, it'll take half the time to get home. But if your speed gets halved, it'll also take double the time to get home.

So, if at 60 mph it takes 1 hour to get home, then if your speed is divided by four to 15 mph, you need to multiply the time by the same number and thus the answer is 4.

Can somewon help me plz can somewon help me

Karolina [17]

Hey there! I'm happy to help!

Let's look at our diameters.

$1*10^2^1\\5*10^2^2$

We want to see how many times greater the diameter of the IC 1101 is than the Milky Way. So, we will divide it's diameter by the diameter of the Milky Way.

$\frac{5*10^2^2}{1*10^2^1} \\$

We divide the numbers without exponents, giving us 5. Then, we divide the 10s with exponents. When dividing exponents, you subtract the numbers in the exponent to get your result. For example, x³÷x²=x

$\frac{5*10^2^2}{1*10^2^1} = 5*10=50$

Therefore, your answer is 50.

Have a wonderful day! :D

Alright, so there are three answers. Start with 3, and for each question you answer, you can select three more, so it's 3*3 for two questions and so on, resulting in 3^8= 6561

This is assuming you mean <span>how many ways can you answer the test, not the question</span>

If the perimeter of one face of a cube is 22.4 cm, determine, to the nearest hundredth, its lateral surface area. *

mr Goodwill [35]

22.4/4 = 5.6 cm

5.6^2 = 31.36 cm^2 per side

Since the later surface area only counts for 4/6 sides on the cube, (31.36)(4) = 125.44 cm^2
