Hi!

First make the denominators the same.

$\frac{8}{20} + \frac{10}{20} = ?$

Add the numerators

$\frac{8}{20} + \frac{10}{20} = \frac{18}{20}$

Simplify to get your answer

The answer is $\frac{9}{10}$

Hope this helps! :)

How many feet are there in 24 yards? A. 288 B. 8 C. 2 D. 72

Mkey [24]

First of all we need to know that 1 yard has 3 feet inside of it
but in order to find 24 yards we would have to multiply by 3 sooo
24 x 3 = 72
so that means there are 72 feet in 24 yards.
In other words the answer is D:)
hope this helps:P

A projectile is launched into the air. The function h(t) = –16t2 + 32t + 128 gives the height, h, in feet, of the projectile t s

Zinaida [17]

Answer:

t = 4 seconds

Step-by-step explanation:

The height of the projectile after it is launched is given by the function :

$h(t)=-16t^2+32t+128$

t is time in seconds

We need to find after how many seconds will the projectile land back on the ground. When it land, h(t)=0

So,

$-16t^2+32t+128=0$

The above is a quadratic equation. It can be solved by the formula as follows :

$t=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}$

Here, a = -16, b = 32 and c = 128

$t=\dfrac{-32\pm \sqrt{(32)^2-4\times (-16)(128)} }{2\times (-16)}\\\\t=\dfrac{-32+ \sqrt{(32)^2-4\times (-16)(128)} }{2\times (-16)}, \dfrac{-32\- \sqrt{(32)^2-4\times (-16)(128)} }{2\times (-16)}\\\\t=-2\ s\ \text{and}\ 4\ s$

Neglecting negative value, the projectile will land after 4 seconds.
