Answer:

A) x = 94

Step-by-step explanation:

To solve this, you first need to know that the angle of the entire line is a total of 180 degrees.

Using this information, create the equation: (x) + (x - 8) = 180. Combine like terms to get 2x - 8 = 180. Add 8 to both sides to get 2x = 188. Now divide 2 from both sides to get x = 94.

Hope it helps!

You have a choice between 2 jobs, one pays $8.25/hr but requires you to spend $20 to get a uniform. The other pays $7.50/hr. At

Veronika [31]

Step-by-step explanation + Answer:

x = 1st job

y = 2nd job

x + y = 22......x = 22 - y

7x + 8.25y = 171.50

7(22 - y ) + 8.25y = 171.50

154 - 7y + 8.25y = 171.50

-7y + 8.25y = 171.50 - 154

1.25y = 17.50

y = 17.50 / 1.25

y = 14 <== 14 hrs at the 8.25 per hr job

x + y = 22

x + 14 = 22

x = 22 - 14

x = 8 <=== 8 hrs at the 7 per hr job

A ball is launched into the sky at 19.6 feet per second from a 58.8 meter tall building. The equation for the ball’s height, h,

zhenek [66]

Answer:

Therefore,

The ball strike the ground at time , t = 6 s

Step-by-step explanation:

Given:

The equation for the ball’s height, h, at time t seconds is

$h=-4.9t^{2}+19.6t+58.8$

To Find:

time, t = ? (When the ball strike the ground)

Solution:

When the ball strike the ground height, h will be ZERO,

So put h = 0 in above given equation for time,

$0=-4.9t^{2}+19.6t+58.8$

Which is a Quadratic Equation

Dividing throughout by - 4.9 we get

$0=t^{2}-4t-12$

On Factorizing, splitting the middle term we get

$t^{2}-6t+4t-12=0$

$t(t-6)+2(t-6)=0\\\\(t+2)(t-6)=0\\\\t=-2\ or\ t=6$

As time cannot be negative,

t = 6 s

Therefore,

The ball strike the ground at time , t = 6 s
