It takes 8 people to pull a 16 ton truck. How many people would it take take to pull a 60 ton truck? I got 30 people am I right? If not can you tell me the answer with work? (:

Answers

8 people pull a 16 ton truck
we can make that a proportion
8:16 
which can be reduced to 
1:2 

that means 1 person can pull 2 tons

to pull a 60 ton truck, you would have a proportion of
x: 60 = 1:2

cross multiply and you get

60 = 2x
x = 30

yes, you're right!

Answer: y=2x^(2)-5x+7

Step-by-step explanation:

The quadratic equation in its standard form is:

y=ax^(2)+bx+c

Now, we are given 5 points of the parabola (if you graph a quadratic equation you will have a parabola), however we only need to choose three points to find the coeficients a, b and c in the quadratic equation.

So, let's choose the first three points:

(-1,14):

14=a(-1)^(2)+b(-1)+c

14=a-b+c(1)

(0,7):

7=a(0)^(2)+b(0)+c

7=c(2)

(1,4):

y=2x^(2)-5x+7

4=a(1)^(2)+b(1)+c

4=a+b+c(3)

Substituting (2) in (1) and (3):

14=a-b+7(4)

4=a+b+7(5)

At this point we have a system with two equations.

Adding (4) to (5):

18=2a+14(6)

Isolating a:

a=2(7)

Substituitng (7) in (3):

4=2+b+7(8)

Isolating b:

b=-5(9)

Now we have the three coeficients and we can write the quadratic equation:

y=2x^(2)-5x+7

on your birthday, you deposit $540.00 in an account that pays 6% interest, compounded annually. How much is in the account 3 years later?

Answers

so, you would do this:

6%= 0.06
0.06 times 3
0.18
Then, make that into 18 by multiplying by 100!

Lastly, add 18 and you're done! Hope this helped!
