He answered .85, 85% or 17/20 correct on the test.
Answer:
The slope is -4.5
The slope means that Elijah's phone battery will decrease by 4.5 percent each hour.
Step-by-step explanation:
In the equation y = mx + b, m is the slope.
The coefficient in the equation B = 27 – 4.5t is -4.5. This means that -4.5 is the slope of the equation.
In the context of this problem, the slope will represent the percent that Elijah's phone battery will decrease per hour.
So, the slope means that Elijah's phone battery will decrease by 4.5 percent each hour.
4 to 7
or
4+7= 12
4x+7x=33
x=3
so,
(4×3)+(7×3)=33
12+21=33
or
12 and 21.
hope it helped
Answer:
Step-by-step explanation:
Given that ∆KLM ~ ∆RSK, 
(similarity theorem)
KL = 65
KR = 65 - 52 = 13
KM = 60
KS = ?
Cross multiply
Multiplying 3/7 by the reciprocal of -3/14,
