Step-by-step explanation:

To find how many people lived outside of the country we subtract:

3.853 × $10^{9}$ - 1.114 × $10^{8}$ = 3.7146 ×

To find the percentage of people living inside the country, we divide: $\frac{1.114 x10^{8}}{3.853 x10^{9}} =2.8913x10^{-2}$ percent or 2.89%. Which is extremely small.

A quarter circle is attached to the side of a square that is 8 cm.

N76 [4]

You have to find the area of both circle and square first then add the answers u get together.

Quarter circle:
A = 3.14 (radius(^2)
A= 3.14(4^2)
A= 3.14(16)
A=50.24cm ^2

Square:
A = b×h
A = 8×8
A = 64cm^2

Then add the answer together.
64 + 50.24 = 114.24cm ^2

the answer is 114.24 or 114.2

H=7+44t-16^2

zalisa [80]

Answer:

When t=2.1753 & t=.5746 , h=27

Don't worry, I got you. Also, my calculator does too.

We set h equal to 27, because we want the height to be 27 when we solve for t.

That leaves us with:

27 = 7 + 44t - 16t^2

Simplify like terms,

20 = 44t - 16t^2

Move 20 onto the right side, so we can use quadratic equation

44t - 16t^2 - 20 = 0 --> -16t^2 + 44t - 20

Using quadratic, you get

t=2.1753 & t=.5746

<u>poster confirmed : "It’s t=2.18 and t=0.57"</u>
