Answer:
Concept: Numerical Analysis
- We want a number say X that represented as a percentage gives us 1,002.54
- Hence 539 × X = 1,002.54
- X = 1.86 %
Step-by-step explanation:
the arc length of a while circle of 360° is the circumference of the circle, which is
2×pi×r
now, our radius r is 15 in.
and we are not dealing with the whole circle of 360° but only with a fraction of that : 30° out of the 360°
so, the arc length is
2×pi×15×30/360 = 2×pi×15×1/12 = pi×15/6 = pi×5/2 =
= 7.853981634... in
Answer:
7=150
Step-by-step explanation:
Each lap is worth $7, so if Mu walked laps and the total is $150, then the equation would be
7=150
There are a few ways to get -15 to equal -3 one is put +12
-15+12=-3
Or putting /5
-15/5=-3
(If i am doing this wrong please explain the question a little more.
Answer:
y =
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 7 when x = 3
k = = , thus
y = x ← equation of variation
When x = 7, then
y = × 7 =
