I cant seem to get it can you help me, please.

Jane took a piece of cardboard and cut out a triangle with measure 32°, 58°, and 90°, and side lengths 5 cm, 12 cm, and 13 cm. W

ioda

The answer is A. Right, Scalene.

This is because 90 degrees = a right angle

32 and 58 are smaller than 90, making it acute or scalene.
Isosceles means at least two sides are equal.
Equilateral means all sides are equal.

In this case, it is not isosceles or equilateral because the sides are not unequal.
It isn’t D. because that option doesn’t say “right”

A factory has three machines making energy drinks. When all three machines are running, 520 drinks are made each hour. When only

Vinil7 [7]

Let A, B and C be the amount machines A, B and C, respectively, produce each hour alone.

With all three machines together produce 520 drinks each hour, we know that the addition of the amount that each produces each hour is equal to 520, that is.

$A+B+C=520_{}$

Now, similarly, machines A and B produce together 320 drinks each hour, so the sum of the amounts A and B produce each hour is equal to 320, so:

$A+B=320$

If machine C produce 30 more drinks than B each hour, than the amount of B plus 30 will be the amount of C:

$C=B+30$

So, we got the system of equations:

$\begin{gathered} A+B+C=520 \\ A+B=320 \\ C=B+30 \end{gathered}$

To solve, notice that A + B is known, because of the second equation, so we can substitute A + B by 320 in the first equation:

$\begin{gathered} (A+B)+C=520 \\ 320+C=520 \\ C=520-320=200 \end{gathered}$

Now, we can substitute C into the third equation and solve for B:

$\begin{gathered} C=B+30 \\ 200=B+30 \\ B+30=200 \\ B=200-30=170 \end{gathered}$

And, finally, we can substitute B into the second equation and solve for A:

$\begin{gathered} A+B=320 \\ A+170=320 \\ A=320-170=150 \end{gathered}$

Answers:

First box:

$A+B+C=520$

Second box:

$A+B=320$

Third box:

$C=B+30$

Fourth box:

$150$

A test of a new car results in 420 miles in 20 gallons . How far can you drive in 65 gallons

amid [387]

To find the number of miles driven on one gallon, divide 420 by 20. that would be 21. multiply 21 by 65 to find the number of miles you can drive with 65 gallons.

A company that manufactures guitars has a fixed cost of $100,000. It costs $100 to produce each guitar and the selling price is

miv72 [106K]

a. Write the cost function:: C(x) = 100x + 100,000 where x is number of guitars

---------------------------------

b. Write the revenue function:: R(x) = 300x where x is number of guitars

-----------------------

c. Find the profit function.

Profit = Revenue - Cost

P(x) = R(x) - C(x)

P(x) = [ R(x) ] - [ C(x) ]

P(x) = [ 300x ] - [ 100x+100,000 ]

P(x) = 300x - 100x-100,000

P(x) = 200x - 100,000

The break even point is when the profit is 0 dollars. You don't lose any money. And you don't gain any money.

Solve 125x - 100,000 = 0

125x = 100,000

x = 800 (# of guitars made and sold)
