Easy bruh

Answer:

631ml

Step-by-step explanation:

In order to find how much water is in the snow globe, we need to find it's volume. Volume formula for the sphere is πr²

π(3.5)² ≈ 38.5in³

To know how much water is in the sphere, we can transform 38.5in³ into milliliters.

1 cubic inch is 16,3871 ml

38.5 x 16,3871 ≈ 631ml

Step-by-step explanation:

We need to do LCM in this case.

2_|_ 6,4,16

2 _|_ 3,2,8

_|_ 3, 1,4

It is not divisible further.

So, LCM is 2×2×3×4 = 48

<u>So, 48 is the answer.</u>

Hope it helps :)

fomenos

Answer: It will take 4 seconds for the rock to hit the water.

Step-by-step explanation:

Given : Benjamin threw a rock straight up from a cliff that was 48 ft above the water.

If the height of the rock h, in feet, after t seconds is given by the equation

$h = -16 t^2+ 52 t + 48$

To find : Time taken for the rock to hit the water.

When rock hit the water height becomes zero , i.e. put h = 0 , we get

$-16 t^2+ 52 t + 48 =0$

Divide equation by 2 , we get

$-8t^2+26t+24=0$

The Laue of x for ax²+bx+c =0 is $x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

So , $t=\frac{-26\pm\sqrt{(26^{2}-4(-8)(24))}}{2(-8)}$

$t=\dfrac{-26\pm 38}{-16}\\\\ t=-\dfrac{-26+38}{-16}=-0.75\ \ t=\dfrac{-26-38}{-16}=4$

Since t cannot be negative , so t= 4

Hence, it will take 4 seconds for the rock to hit the water.

mrs xu lives 10.7 miles away from her place of work. she drives to work and back six days a week. how many miles does she travel

rewona [7]

Answer:

128.4 Miles

Step-by-step explanation:

She goes to work and goes 10.7 miles, and then goes back home aswell which is also 10.7 miles. So total miles in one day = 10.7 + 10.7 = 21.4 miles in one day.

so 1 week = 21.4 x 6

128.4 miles.

we times it by 6 because she works 6 days a week only.

hope it helped :)
