Answer 2
the answer is 146.154

your solving for the hypotenuse, which is always c in the pythagorean theory .

so a2+b2=c2
a=144 ,b=25 ,c=x
144 squared +25 squared =x squared
20,736 + 625=x
20,736+626=21,361
then square root 21,361 .
146.154 is your answer

Point Form:

(-1/4, -7/8)

Equation Form:

x= -1/4, y= -7/8

Step-by-step explanation:

Answer:

x=-4, y=-6.5

Step-by-step explanation:

First, we need to find the value of x so

x+2=-2

-2 -2

x=-4

now plug the value of x, in the second equation

-3(-4)+2y=-1

12+2y=-1

minus 12 from both sides

12+2y=-1

-12 -12

2y=-13

divide by 2 to get the value of y

y=-6.5

-4x + 2 = -18

subtract 2 from both sides

simplify

x = 5

Creed's brother earns $12.00 per hour. The store offers him a raise -- A 5% increase per hour. After the raise, how much will Creed's brother make per hour?

Answers

12+0.6=12.6
So after the raise Creeds brother will make $12.60/hour

A tower 15m high casts a shadow 30m long. A nearby telephone pole casts a shadow 16m long. Find the height of the telephone pole. Plz show ur work, thx slatttttt

Answers

Answer:

8 feet.

Step-by-step explanation:

If we know the shadow (30 ft) of a tower (15 ft), we can use use the ratio

[tex]\frac{30}{15}=\frac{16}{x}[/tex] where 'x' is the height of the telephone pole. Cross multiply, and we get the equation [tex]240=30x[/tex]. The rest of the problem is pretty straightforward, we divide both sides by 30 to find x. In the end, you will find that the height of the telephone pole is 8 feet.

Hope this helped!

The answer should be 8 feet
