Answer:
13 levels
Step-by-step explanation:
Direct variation can be expressed using the formula:
y = kx, where 'k' is the constant of variation
Since Michael can move up 5 levels in 55 minutes:
n = km, where 'n' is the number of levels and 'm' is the number of minutes:
5 = 55k
k = 1/11
To find the number of levels after 143 minutes:
n = (1/11)(143)
n = 13 levels
Answer:
D. 9, 12, 15
Step-by-step explanation:
You can use the Pythagorean Theorem to solve.
a^2 + b^2 = c^2
9^2 + 12^2 = c^2
81 + 144 = 225
Remember, c is squared.
The square root of 225 is 15.
D is the only answer that is correct.
Just simply divide
ALSO REMEMBER: That if there's one or an odd number of negative in multiplication or division the answer would be negative
-20/5= -4
So
b= -4
There are 108 inches in 9 feet but there are 5 so 108×5= 540 so to get your answer you need to divide that by 15 which equals 36. so you can make 36 pieces
