Answer:
PC = 8
Step-by-step explanation:
BF and CE are medians of the triangle.
On each median the distance from the vertex to the centroid P is twice as long as the distance from the centroid to the midpoint, then
PC = 2 × EP = 2 × 4 = 8
Answer:
$18.90
Step-by-step explanation:
The way to do percentages is actually pretty easy.
since it's taking 30% of you are left with 70%. Take 70 and divide it by 100. This gives you .70
Now what you do is you take the price of the time and multiply it by the .70
So 27.00 * .7 = 18.90
So Noah paid 18.90
Answer:
J = -2
Step-by-step explanation:
You must isolate the variable by dividing each side by factors that dont contain the variable.
So J would equal -2

Answer:
Step-by-step explanation:
From the given table,
A. The unit rate for each car is,
Car A = 
= 32 miles per gallon
Car B = 
= 34 miles per gallon
Car C = 
= 35 miles per gallon
Car D = 
= 31 miles per gallon
B. From the derived values in A, the car that uses the least amount of gas is Car C.
C. Total distance covered = 496 miles x 4
= 1984 miles
The gallons of gas the Car A would need for the journey can be determined by;
Car A requires 1 gallon for 32 miles
So that for 1984 miles = 
= 62 gallons
Car A would need 62 gallons of gas to make the trip.
D. Amount spent on gas for Car A = $2.12 x 62
= $131.44
E. speed = 
⇒ time = 
Given the for Car A, speed = 68 miles per hour.
time = 
= 29.1765
time = 29 hours
It would take approximately 29 hours for Car A to cover the total distance of 1984 miles.
