Answer:
(a) a squared + 15 squared = 17 squared
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the sides is equal to the square of the hypotenuse.
a^2 + 15^2 = 17^2 . . . . . . matches the first choice
Answer :- parallelogram
Step-by-step explanation:
1/12 + 1/6x = 3/4...multiply everything by common denominator of 12
1 + 2x = 9
2x = 9 - 1
2x = 8
x = 8/2
x = 4 <== he can play 4 rounds
Given:
Total tips = $ 77.40
Ratio of tips sharing = 2 : 3 : 4
To find:
How much more does Brian get over Paul
Solution:
Let 2x, 3x and 4x be the cost of tips got by Paul, Colin and Brian.
Total cost of tips =$ 77.40
2x + 3x + 4x = 77.40
9x = 77.40
Divide by 9 on both sides.
x = 8.6
Brian gets = 4(8.6) = $34.4
Paul gets = 2(8.6) = $17.2
Difference = 34.4 - 17.2
= 17.2
Therefore Brian gets $17.2 more than Paul.
