There are five times as many cars as trucks on the road. Which fraction represents the number of vehicles that are trucks?
jonny [76]
Well, the ratio of cars to trucks is 5:1, so for every 1 truck, there are 5 cars, the sum would be 6. So that's the denominator, and then the numerator would be 1, since there's only 1 truck out of every 6 vehicles.

The age of a father is two less than seven times the age of his son in two years the sum of their ages will be 57 if the son's p
ASHA 777 [7]

Answer:

f = 7s -2

f  + s =53

Step-by-step explanation:

Given

Let

f = Father's age

s = Son's age

We'll solve this question, while reading through the instructions

From the first statement;

f is 2 less than 7 times s.

This means

f = 7s -2

In two years time, the father will be f +2 and the son will be s + 2

So, their sum is:

(f+2) + (s + 2) = 57

f + 2 + s + 2 =57

Collect like terns

f  + s =57-2-2

f  + s =53

So, the equations are:

f = 7s -2

f  + s =53

The surface area, S, of a sphere of radius r feet is S = S(r) = 4πr^2. Find the instantaneous rate of change of the surface area
vesna_86 [32]
This is the derivative of S with respect to r, evaluated at r=8.
dS/dr = 8πr
Substituting r=8 into the above gives the answer of 64π.

Find the area of the triangle.<br><br> Be sure to label your answer. Round to the nearest hundredth.
olga2289 [7]
Your answer would be 31.5 (so 32 when rounded up)

For triangles you basically multiply them together, and the divide your answer by two. 

A= 1/2 b x h 
A= 1/2 7 x 9
A= 1/2 63
A= 31.5 (rounded up to 32)

I hope I helped and if you need more you could always ask me :)
