1 yd = 3 ft
area= pi r ^2
area=3.14 • 3^2
area= 3.14 • 9
area= 28.26ft^2
rounded to nearest 10th: 28.3 ft^2
ANSWER: J. 28.3 ft 2
Answer: 7 miles per hour
Step-by-step explanation:
This is a fraction equal to 28 miles divided by 4 hours.
We want a unit rate where 1 is in the denominator, so we divide top and bottom by 4.
28 miles ÷ 4
____________
4 hours ÷ 4
= 7 miles
__________
1 hour
=
7 miles
_________
hour
= 7 miles per hour
Answer:
I think it's y = 3/2x - 5
Step-by-step explanation:
when we multiply the slopes of perpendicular lines, we get -1
Step-by-step explanation:
Let the two numbers be X and Y respectively.
<u>We know that</u> :
(a) X = 6Y + 5
(b) X + Y = 75
7Y + 5 = 75
X = 65
Y = 10
we know that

in this problem we have

so
equate

substitute

therefore



rewrite as perfect square


therefore
<u>the answer is</u>
the solution set is
