Answer:

the awnser is 135

Step-by-step explanation:

15 × 9 = 135

Answer:

54 m^2

Step-by-step explanation:

Area = 1/2 * base * height

You are missing height, but because you have the hypotenuse, you can use the Pythagorean Theorem to find it.

height^2 + (9m)^2 = (15m)^2

height = sqrt(225 m^2 - 81 m^2)

height = sqrt(144 m^2) = 12m

Area = 1/2 * 9m * 12m = 54 m^2

Liam and his children went into a restaurant and where they sell drinks for $2 each and tacos for $3.50 each. Liam has $30 to spend and must buy at least 9 drinks and tacos altogether. If Liam decided to buy 5 tacos, determine the maximum number of drinks that he could buy. If there are no possible solutions, submit an empty answer.

Answers

answer: the maximum number of drinks Liam can buy is 4 without over exceeding his price limit.

work:
$3.50 for 5 tacos is $17.50
9 - 5 tacos = 4 drinks
4 drinks x $2 = $8
$17.50 + $8 = $25.50 out of $30 price limit

x^2 - 55 = 26

Answers

Answer:

x = ±9

Step-by-step explanation:

I'm not sure what 15y3 is, but I'll take a guess.

If the only numbers are 15, 3, and -40, then the greatest common factor is 1.

If the only numbers are 15 and 3, then it's three.

If the only numbers are 15 and -40, it would be 5.

He would be paid $15 million dollars per year for 14 yearsan additional 7 years beyond the end of the time he would be committed to play for the Nationals. The contract was widely reported as being worth $210 million (or $15 million per year14 years). One baseball writer argued, though, that "this deal serves as a nice reminder that the payment terms of a deal can have an impact on the actual value of the contract." Source: Dave Cameron, "Max Scherzer and When $210 Million Isn't $210 Million," fangraphs, January 19, 2015. Which of the following statements best represents the actual value of the contract? A. The actual value of the contract is more than $30 million for each year he plays. B. Scherzer's contract is worth $210 million on the day he signs it. C. The actual value of the contract is less than $30 million for each year he plays. D. The actual value of the contract is $30 million for each year he plays.
