The degree of a line is 180, so..

Put it into an equation form: 5x + 75 = 180

1st combine like terms by subtracting 75 from 180

now your equation looks like this: 5x = 105

next you divide 5 from both sides, 105 divided by 5 is 21, so your answer is: x=21


I hope this helps!♥

The value of a car is $30,000. It loses 6.5% of its value each year. What will the value of the car be after 5 years?
Kitty [74]
Decay equation= P*(1-r)^t
P= Principal amount= $30,000
r= rate=0.065
t= time (in years) =5
x=30,000(1-0.065)^5
The value of the car in 5 years is approx. $21,438

Find the coordinates of a point on the directed segment from (-3,6) to (7,1) that divides it into a ratio of 3:1.
Masja [62]

Step-by-step explanation:

To divide a directed segment, we need to divide the length of the segment, along the x and the y directions separately.  Then add the subdivided segment to the starting point of the directed segment (-3,6) to get the point of division.

Let the length be denoted by delta, then

delta = (7,1) - (-3,6) = (10,-5)

Multiply delta by the ratio of 3 / (3+1) = 3/4

(10,-5) * 3/4 = (7.5, -3.75)

Add the subdivided segment to the starting point:

(-3,6) + (7.5, -3.75) = (4.5, 2.25)

So the point of division is (4.5, 2.25)

A company rents water tanks shaped like a cylinders. Each tank has a diameter of 12 feet and a height of 3 feet. The cost is $2
12345 [234]

Answer:

\$678.58

Step-by-step explanation:

step 1

<u>Find the volume of the tank</u>

we know that

The volume of a cylinder (water tank) is equal to

V=\pi r^{2}h

in this problem we have

r=12/2=6\ ft -----> the radius is half the diameter

h=3\ ft

substitute

V=\pi (6^{2})(3)=339.29\ ft^{3}

step 2

Find the cost

339.29\ ft^{3}*2\frac{\$}{ft^{3}}=\$678.58
