Answer:
12700
Step-by-step explanation:
45 + .05x = 680
.05x = 635
x = 12700

Answer:
I Think you Got All of them Right but the Last Two
Answer:
1.5 seconds
Step-by-step explanation:
The height equation is supposed to be ...
h(t) = -16t^2 +22t +3
We want to find the positive value of t where h(t) = 0.
0 = -16t^2 +24t -2t +3 . . . . facilitate factoring
0 = -8t(2t -3) -1(2t -3) . . . . . factor by pairs
0 = -(8t +1)(2t -3) . . . . . . . . complete the factoring
The solutions to this are ...
t = -1/8, 3/2
The ball will reach the ground in 1.5 seconds.
Answer:
m∠A = 139°
Step-by-step explanation:
First we must know that
Supplementary angles equal to 180 degree.
Since we know that supplementary angles equal to 180 degree we can solve now:
Putting m ∠A and m ∠ B together and put the = 180
( 7x - 15 ) + ( 2x - 3 ) = 180
Now solving for x:
( 7x - 15 ) + ( 2x - 3 ) = 180
9x - 18 = 180
9x - 18 + 18 = 180 + 18
9x = 198
9x/9 = 198/9
x = 22
Hence, Angle A will have a measure of 7x - 15 which means 7 × 22 -15 = 154 - 15 = 139°
m∠A = 139°
The measure of Angle B will be 2x - 3 = 2 • 22 - 3 = 44 - 3 = 41°
m∠ B = 41°
139 + 31= 180
