What percent of 55 is 13
percent means parts out of 100
x%=x/100
'of' means multiply
what percent of 55 is 13 means
x/100 times 55=13
times both sides by 100
55x=1300
divide both sides by 55
x=23.63636363636363
answer is 23.63%
Answer: 8 times 6 equals 48
Answer:
The area of the sector is 84.8 in.² to the nearest tenth
Step-by-step explanation:
∵ the clock is a circle
∴ The measure of angles between each two hours = 360° ÷ 12 = 30°
∵ At 8 o'clock the hour hand pointed on 8 and the minute hand pointed on 12
∴ There are 4 angles between the two hands
∴ The central angle subtended by the arc = 4 × 30° = 120°
∵ The Area of the sector =
where x is the central angle subtended by this arc
∴ Area sector =
× π × (18/2)²
∴ Area sector =
× π ×81 = 27π = 84.8 in² to the nearest tenth
Let y represent the total weight of mulch and x represent the number of bags of mulch, then
y = kx.
Rate of change (k) = y/x. i.e. the weight of mulch divided by the number of bags.
