<span>Sheila can ride her bicycle 6000 meters in 15 minutes.
Forming that into a ratio, that will be 6000 : 15
Doing the proportion for 2 minutes.
6000 : 15 = X : 2
Doing the computation.
6000 / 15 = X / 2
15X = 2 * 6000
15X = 12000
X = 800
So Sheila covered a total of 800 meters in 2 minutes.</span>
Answer:
7-12 is -5
Step-by-step explanation:
Answer:
She needs to score 82
Step-by-step explanation:
Mean of five test scores = 82
Let the score she got in fifth test = x
Use the sine rule.
For any triangle: sin(a) / A = sin(b) / B = sin(c) /C
Where A is the side opposed to angle a, B is the side opposed to angle b, and C is the side opposed to angle c.
Here, sin(B) / AC = sin(A) / BC = sin (C) / AB
<span> BC = 12.35, AC = 8.75 centimeters, and m∠B = 37°
sin(37) / 8.75 = sin(A) / 12.35 => sin (A) = 12.35 * sin(37) / 8.75
sin(A) = 0.845 = A = arctan(0.845) = 58.15°
And A + B + C = 180° => C = 180 - A - B = 180 - 58.15 - 37 = 84.85
Answer:
measure of angle A = 58.15°
measure of angle C = 84.85 °
