radius = (4*10^2 + 24^2)/8*10 =

(400 + 576)/80=

976/80 = 12.2

diameter = 12.2 x 2 = 24.4

Please help me with my pre-algebra ASAP

dexar [7]

The sum of the measures of two complementary angles is 90°. To put it another way, m∠P + m∠Q = 90°.

So, we can substitute the given values of the angles into this equation.

$(52)+(3x+2)=90 \\ \\ 3x+54=90 \\ \\ 3x=36 \\ \\ x=12$

Then, to find m∠Q, we plug in 12 for x for the original expression of Q to get $3(12)+2=38$ .

Ric sells shirts. It costs him $100 to buy all the shirts and $10, total, to print designs on them. Eric sells each shirt for $4

Lynna [10]

First, you'll want to identify the given in the problem.

It costs 100 dollars to purchase all of the shirts and 10 dollars to print the designs on the shirts. The result being a 110 dolar investment prior to his sales. In addition, each shirt is sold for 4 dollars and this becomes the slope of the equation.

Using this info the following equation can be used to find Eric's profit:

P=4x-110

With 4 being the slope.

Overall, after selling the 20 shirts by plugging 20 in for x we get 80-110. So his profit is -30 dollars.

Hope this helps :)
