9700 is the answer which is correct
Answer:
14
Step-by-step explanation:
you can simplify it by turning a²+b²/a-b
into
(a-b)²+2ab / a-b
eliminate the fraction
a-b +2ab
a=-1
b=-5
-1-(-5)+2*-1*-5
-1+5+10 = 14
Answer:
3 cm
Step-by-step explanation:
First, find the volume of the cone.
V = 
r²h
V = (3.14)(9)(12)
V = 113.04
This means the sphere is also 113.04
Use the formula V = 
r³
113.04 = (3.14)r³
113.04 = 4.19r³
26.98 = r³
3 ≈ r
We'll represent the distance as d and the time as t.
d= 3(t+7) because Gilda is 7 minutes late when travelling 3 mph
d= 4(t-5) because Gilda is 5 minutes early at 4 mph
d= 3t + 21
d= 4t -20
3t +21 =4t -20
41=t
d= 3(41) +21= 144
The distance is 144 miles.
Answer:
24 ÷ 4
Step-by-step explanation:
Putting something into fourths is putting into 4 parts. If you divide 24 by 4 you get 6. 6 equals 1/4 of 24. To check your work add 6 together 4 times.
