I did it and got 36.

The answer would be 36.

Following PEMDAS, you'd solve what's in the parenthesis first. 2^2 = 4 and 3^2 = 9. This leaves you with 10 + (4 + 9) x 2. Add 9 and 4 to get 13, and then the parenthesis are done.

Next, you'd multiple 13 and 2 (since it's the next step in PEMDAS) to get 26.

Finally, you add together 10 and 26 to get the answer, which is 36.

I hope this helps!

Help me please with some of my math homework I don’t really understand what p is equal to

horrorfan [7]

The value of p is 5.

Step-by-step explanation:

step 1 : The given expression is -6( p -5 )

step 2 : To find any unknown value in an expression, equate it to zero.

step 3 : -6( p -5 ) = 0

step 4 : Multiply -6 to each term in the bracket.

-6p + 30 = 0

-6p = -30

p = -30/-6

p = 5

Rays PQ and PS are perpendicular to each other. What is the measure of LRPS plzzzzz

inna [77]

Answer:

m<RPS = 53 degrees

Step-by-step explanation:

Find the diagram attached

From the diagram shown;

m<QPR + m<RPS = 90

Given that;

m<QPR = x

m<RPS = x+16

Substitute into the formula;

m<QPR + m<RPS = 90

x+x+16 = 90

2x+16 = 90

2x = 90-16

2x = 74

x = 74/2

x = 37degrees

Get m<RPS;

Since m<RPS = x+16

m<RPS = 37 + 16

m<RPS = 53 degrees

Suppose that you and a friend are playing cards and you decide to make a friendly wager. The bet is that you will draw two cards

Serjik [45]

Answer:

Step 1: Expected value = -2.53 dollars

He makes - 1,803.89 dollars over 713 of these bets.

Step 2:

Step-by-step explanation:

Expected value of bet = (Winning probability * winning amount) - (losing probability * losing amount)

Winning probability = (13/52) * (12/51) = 0.0588

Losing probability = 1 - 0.0588 = 0.9412

Expected value = (37 * 0.0588) - (5 * 0.9412)

Expected value = -2.53 dollars

If this same bet of expected value -2.53 dollars is made 713 times, our expected losses are:

2.53 * 713 = 1,803.89 dollars

Thus he makes - 1,803.89 dollars over 713 of these bets.

You plan to charge $10 per shirt for the first 50 shirts. If you order more than $50 shirts you plan to sell each shirt for $8 e

Juliette [100K]

Answer:

You would charge 1,100 dollars.

Step-by-step explanation:

Since the first fifty shirts are 10 bucks each, you would subtract that 50 from 125, which gives you 75. Now with that 50,you would multiply it by 10, which is 500. Now put that 500 to the side, and do your remaining 75 times the 8 dollars that is now being charged. You should get 600. Finally, you add the 500 that you put aside and the 600 to get 1100.
