Answer: 89.7 ft
<u>Step-by-step explanation:</u>
Find the arc length (s) of the semi-circle. Then divide that length by 7.
s = r · θ where r is the radius and θ is the angle in radians
s = (400 ÷ 2) · π <em>(radius is diameter divided by 2)</em>
= 200π
= 628.3
The length of the arc is 628.3 ft. Divide that by 7 to find the distance between each home.
628.3 ÷ 7 = 89.7
Answer:
20

-4 is the slope in the equation
Answer:
900 calories
Step-by-step explanation:
First you have to find the unit rate, how many calories are there in ONE cracker? To find that you have to divide 60 ÷ 12 = 5 and to check with the other one, 75 ÷ 15 = 5
So, one cracker is 5 calories. Now, how many calories are in 180 crackers? You multiply, 180 x 5 = 900
That means there are 900 calories in 180 crackers.
Hope that helps and have a great day!
