The answer is C
P is half of QRS
R is half of SPQ
<span>so angles P and R are complementary.</span>
Make ratios.
12/16: 15/x
cross multiply
12(x) = 12x
16(15) = 240
12x = 240
isolate the x, divide 12 from both sides
12x/12 = 240/12
x = 20
D) 20 km is your answer
hope this helps
Answer:
constant of variation = 1.2
Explanation:
y varies directly with x means that as x increases, y increases and vice versa.
This can be translated into the following equation:
y = kx
where k is the constant of pvariation.
We are given that:
y = 12 when x = 10.
Therefore, we will substitute with these values in the above equation and solve for k as follows:
y = kx
12 = k * 10
k = 12 / 10
k = 1.2
This means that the equation relating x and y is:
y = 1.2x
where 1.2 is the constant of variation.
Hope this helps :)
Answer:
15.8
Step-by-step explanation:
round!
Domain refers to all of the x-values that satisfy the line, and the range refers to all of the y-values that satisfy the line.
Since t corresponds to the x-ordinates, then the domain becomes:
0 ≤ t ≤ 6
and the range becomes:
0 ≤ v ≤ 150
In short, the answer is (A)
