The answer:
the total distance of the trip is 821 miles from home,
for this the car <span>gets 24 miles per gallon
</span>the average price of gas is $3.74 per gallon
the price can be calculated as:
for the trip,
24 miles-------------1 gallon
821 miles------------ x= 821/24=34.20 gallons
1 gallon------------- $3.74
34.20 gallons---------x=?
to find this value
34.20 gallons x $3.74 = $127.93.
Answer:
86 cm²
Step-by-step explanation:
Ok, so since 4 circles fit in the square, each circle's diameter must be 10.
Which means the radius of each circle is 5 because 10 ÷ 2 = 5.
Now we can solve for area.
A = πr²
A = 3.14 x 5²
A = 3.14 x 25
A = 78.5 cm²
78.5 cm² is the area of one circle so we multiply that by 4.
78.5 x 4 = 314 cm²
Now we subtract from the area of the square.
20 x 20 = 400 cm²
400 - 314 = 86 cm²
if x^2=40 you would need to square root both sides to get x alone therefore x=6.3
