Answer:
A
Step-by-step explanation:
pi*r²=616
22×r²=616×7
r²=4312/22
r=14
now
2piR=2×22/7×14
=88
Answer:
x = 41
Step-by-step explanation:
119 + 76 = 195
236 - 195 = 41
12.5 yds at 4.50 per yd : 12.5 * 4.50 = 56.25....what she paid for the fabric
she uses 2.5 yds of fabric for each dog bed.....12.5 / 2.5 = 5...so she can make 5 dog beds
each dog bed sells for 17.50.....5 * 17.50 = 87.50
87.50 (what she earned from selling the dog beds) - 56.25 (the cost of the fabric) = 31.25......so her total profit is $ 31.25 <==
Answer:
3:3.5
Step-by-step explanation:
3 feet :42 inches
42 inches=3.5 feet
3 feet:3.5 feet
So if F (×)= 56. When x= 8.
56÷8 = 7
F=7
F(×) = ? when X = 2
7 × 2= 14
F (x) = 14
Hope this helps!
