Answer:
3940.5 cm^3 to the nearest tenth.
Step-by-step explanation:
The radius = 1/2 * diameter = 9.8 cm
Volume V = 4/3 *3.14 * 9.8^3
= 3940.457.
Answer:
-40=a
Step-by-step explanation:
( a-5)/(a+4) = 5/4
Multiply by (a+4) on each side
( a-5)/(a+4) * (a+4) = 5/4 (a+4)
a-5 = 5/4 (a+4)
Multiply by 4 on each side to clear the fractions
4(a-5) = 5/4*4 (a+4)
4(a-5) = 5 (a+4)
Distribute
4a -20 =5a +20
Subtract 4a from each side
4a -4a -20 = 5a-4a +20
-20 =a+20
Subtract 20 from each side
-20-20 =a+20-20
-40=a
Answer:
$8.00
Step-by-step explanation:
Since it says estimate we are rounding. I'm assuming tot he nearest dollar.
$4.95 rounds to $5.00
$1.85 rounds to $2.00
$1.05 rounds to $1.00
Then add these up to see the total estimated cost. $8.00
