Step-by-step explanation:
a = 6
b = 7
c = missing side
112-88 = 24
they save $24 per month
so 650/24 = 27.083
so it will pay for itself in 27.083 months, round up to 28 months
Answer:
it's estimated that 750 students in the whole school dislike the 8:30am start time.
Step-by-step explanation:
Since 30 of the 40 students said "no", it means 30/40, or 3/4 of the random sample disliked the 8:30am start time. Multiply this by the whole population: 1,000 × (3/4) = 750.
Another way to check this is using 10/40 = .25 and doing 1000x.25 = 250 (the amount of students who liked it). Then subtract from whole population and it's 750.
The area of the field is equal to the area of rectangular
a = l × w
Given:
l = 100 yards
w = 20 yards
Solution:
put the numbers to the formula
a = l × w
a = 100 × 20
a = 2,000
The area of the field is 2,000 square yards
