Answer:
7 hours
Step-by-step explanation:
1/14 * 14 = 1 whole lawn
1/2 hours = 30 minutes
14 * 30 = 420 minutes to water entire lawn
420 minutes = 7 hours
Answer:
35
Step-by-step explanation:
If there are "x" of each coin, then the value of the coins will bw (1 + 5 + 10)x, which equals 560 (given).
16x = 560 -->
x = 35
There are 35 of each type of coin
Answer:
b
Step-by-step explanation:
If S is students and n is nonstudents
S = 3n + 11
541 = 6(3n + 11) + 7n
541 = 18n + 66 + 7n
475 = 25n
n = 19
19 nonstudents so then you put that number in the first equation
S = 3(19) + 11
S = 68
68 students attended the movie
Answer:
- w = 8
- x = 8√2
- y = 8√2
- z = 16
Step-by-step explanation:
A 45-45-90 right triangle is isosceles. That means both legs are the same length, and its hypotenuse is √2 times the leg length. You can figure these facts using trigonometry or the Pythagorean theorem, or you can rely on your memory of them.
w = 8 . . . . . . . . . . . same as the leg length shown
x = y = 8√2 . . . . . hypotenuse of smaller triangle; both legs are the same
z = (8√2)√2 = 16 . . . . hypotenuse of larger triangle
