Answer:
The perimeter of the sector is :30.5 cm
Step-by-step explanation:
Mathematically, we have the area of the sector as;
e/360 * pi * r^2
r is 8 cm
so we have
58 = e/360 * pi * 8^2
58/64 * 360/pi = e
e = 103.85
To get the perimeter,
we have length of the arc plus 2r
Length of the arc is;
e/360 * 2 * pi * r
add 2 r;
e/360 * 2 * pi * r + 2r
so we have
103.85/360 * 2 * pi * 8 + 2(8)
= 14.5 + 16
= 30.5 cm
Answer:
176 seconds
Step-by-step explanation:
By using regression line calculator,
Equation of the line of best fit will be,
T = -12.55x + 276.52
Here , T = time taken to cover one lap
x = Age
If the age of Marsha's son is 8 years then expected time taken by her son to cover one lap will be,
T = -12.55(8) + 276.52
T = -100.4 + 276.52
T = 176.12 seconds
Therefore, approximate time taken by Marta's son will be 176 seconds.
There was 16 pieces of fruit
Answer:
a. the difference in lengths of the two pieces of carpet is 1.1m
b. total length of the carpet put together is 8.1m
Step-by-step explanation:
⇒ One piece of carpet is 3.5m long (given)
⇒ Another piece of carpet is 4.6m long (given)
a. What is the difference in lengths of the two pieces of carpet?
⇒ difference means subtract
⇒ 4.6m - 3.5m = 1.1m
b. Simon lays the two pieces of carpet together, end to end, What is the total length of the carpet?
⇒ total length means addition
⇒ 4.6m + 3.5m = 8.1m
127/4 = 31.75 = 31
85/2 = 42.5 = 43
She can only make 31 full gift baskets with the amount of soap she has.
Therefore, Chloe can make 31 gift baskets.
