Answer:
a) PR = 17 cm, b) QR = 6 cm
Step-by-step explanation:
∠Q=90, so PQ and QR are legs, and PR is hypotenuse.
Pythagorean theorem PQ² + QR² = PR²
a) PQ² + QR² = PR²
8² + 15² = PR²
PR² = 289
PR = 17 cm
b) PQ² + QR² = PR²
8² + QR² = 10²
64 + QR² = 100
QR² = 36
QR = 6 cm
The reasonable answer is D makes since
9 pounds of food at 2.00= 18.00
she has 25.00-18.00= 6.00 to buy treays
6÷1=6
Cara can buy 6 treats
Let x be the number of song points.
Let y be the number of videos points.
We have the first expression:
5x + 7y = 295
We have the second expression:
10x + 3y=150
Solve for y and x:
x = (295 -7y)/5
10 ((295-7y)/5) + 3y = 150
590 - 14y + 3y =150
590 - 150 = 14y -3y
y=40 points
solving for x:
x = (295-7*40)/5
x=3 points/song
If she buy, all songs for 333 points
number of songs = 333 / 3
number of songs = 111
The answer is 111.
