X is the shorter base.

Y is 4 less than 3 times x.

This means that if x were to be multiplied by 3, y would be short by 4. If put into an equation it would look like this.

Y = 3x -4

Which number can you add to get a sum of 0<br><br> A . -10<br> B. -5<br> C. 0<br> D. 5
Nikolay [14]
To figure this one out, my pre calculus teacher said to "plug and chug". Since you are adding each number to itself, A=-20, B=-10, C=0, and D=10. So your answer would be C.0

8. At a wholesale food distribution center, the price of sugar has increased 6.3% annually since 1980.
Nitella [24]

Answer: A. $4.12

Step-by-step explanation:

Y=a(1+r/n)^nt is the equation we use to solve this.

a= $0.43

t=37 - take 1980 and subtract it from 2017

r= .063 - the 6.3% goes into a decimal

n = 1

Y= ?

Y= 0.43( 1+ .063/1) ^1*37

Y= 0.43 (1.063) ^37

Y= 4.12

The area of the circle is 144π m2<br><br> What is the diameter of the circle?
Over [174]

Answer:

Step-by-step explanation:

Remember that

Area of Circle = \pi r^2

\pi  = pi \\r = radius

They told us that for this circle, the area is 144\pi  m^2

If you put it back into the formula for area of a circle we get:

Area of Circle = \pi r^2

144\pi = \pi r^2

Divide both sides by \pi.

144 = r^2

Now we want to solve for r (r = radius).

You need to square root each side

\sqrt{144} = \sqrt{r^2}

12 = r

So now we know the radius, r = 12 metres

Also remember that

Diameter = 2r

So,

Diameter = 2 times 12 = 24 metres
