Answer:
The length of the arc is 7.85 in
Step-by-step explanation:
First of all we need to calculate the circumference
To solve this problem we need to use the circumferenc formula of a circle:
c = circumference
r = radius = 10 in
π = 3.14
c = 2π * r
we replace with the known values
c = 2 * 3.14 * 10 in
c = 62.8 in
The length of the circumference is 62.8 in
Now we have to get the relation of the sector with the circle, for this we divide 45° by 360°
45° / 360° = 1/8
we multiply this fraction with the circumference and obtain the length of the arc
62.8 in * 1/8 = 7.85 in
The length of the arc is 7.85 in
Answer:
1/8 , 1/9 , 1/10 ,1/11 , 1/12
Step-by-step explanation:
The expression to solve is : 1/x where
7 < x < 13 ------this means x can be 8, 9 ,10 ,11 , 12 {<em>the case of whole numbers</em>}
The values are :
1/8 , 1/9 , 1/10 ,1/11 , 1/12
Answer:
The container holds 4.5 cups of yogurt
Step-by-step explanation:
Here, given the number of ounces of yogurt in a container, we want to calculate the number of cups the container can hold
Mathematically, we need a conversion factor
1 cup contains 8 ounces
but here
x cups contains 36 ounces
8 * x= 36 * 1
8x = 36
x = 36/8
x = 4.5
Answer:
(b) 625
Step-by-step explanation:
Hello!
To find the answer, we know how much she runs in a minute. We need to find the hour. There are 60 minutes in an hour, so we multiply.0.09 by 60.
She was running 5.4 mph.
