3x - 45 = 2x + 5
3x - 2x = 5 + 45
x = 50

4y - 1 + 2x + 5 = 180
4y + 2(50) + 4 = 180
4y = 180 - 4 - 100 = 76
y = 76/4 = 19.

y = 19

If A = 3r^2h^2, and (rh) increases by 100%, then the new A is how many times greater than the old A? PLEASE HELP ME!!! (Specify

Maslowich

Answer: the answer is 3

Step-by-step explanation:

An increase of 100% in the value of (rh) means the value doubles. When that doubled value is squared, the new area is 4 times the old area.The question asks how many times GREATER the new A is than the old A. 4 times AS LARGE AS is a 300% INCREASE, which is 3 TIMES LARGER THAN.So the grammatically correct answer is 3

Debbie launched a toy rocket off a hill next to Lake Lakewood. The height h of the rocket in feet above the surface of the lake

jenyasd209 [6]

Answer:

t = 8.69 s

Step-by-step explanation:

The height h of the rocket in feet above the surface of the lake can be modeled by :

$h=340+100t-16t^2$

Let we need to find the time to reach the ground. When it reach the ground, h = 0

$340+100t-16t^2=0$

We need to find the value of t.

t = 8.69 s and -2.45 s

Neglecting negative value,

t = 8.69 s

Hence, it will take 8.69 s to reach the ground.
