If Terrence is skating at a constant rate then the answer to b would be it is a function. On a You say how close he is to the motion detector in feet during the second he says. Since the seconds is on the first one 0 then he is 0 feet. Then 2, 4, 6, 8. Because every second he gets to feet colser. On c, the independent variable is how time, and the dependent variable is distance from motion detector. The independent variable is what you change and the dependent variable changes because of the independent variable. Hope this helped!

The number a exceeds the number b by 50 percent. By what percent is the number b smaller than the number a?

inna [77]

Answer:

33 1/3 percent smaller

Step-by-step explanation:

The number a exceeds the number b by 50 percent.

a = b + b*.5

a = b(1.5)

Divide by 1.5

a/1.5 = b

2/3a =b

We want to find (a-b)/a to find the percent decrease

(a-2/3a)/a *100percent

(1/3a)/a* 100 percent

1/3 * 100 percent

33 1/3 percent smaller

An amount of R351 is made up with 114 coins (R2 coins and R5 coins only). How many R2 coins are there? How many R5 coin are ther

lisabon 2012 [21]

Answer:

Step-by-step explanation:

For this, you have to make two equations;

One that calculates the amount of coins

and one that calculates the amount of R

I'm going to set

R2 = x

R5 = y

To make this a bit easier to look at

So to do the number of coins, you want to do this:

x + y = 114

This is saying that the total amount of R2 coins plus the total amount of R5 coins will add up to 114

Then, you want to calculate the worth of them.

2(x) + 5(y) = 351

This is saying that for ever R2 coin there is, it will increase the total by 2, and every R5, it will increase the total by 5. When you add these together, it will come out to 351.

Then you have to solve the system of equations:

x + y = 114

2x + 5y = 351

-2 * (x + y = 114)

2x + 5y = 351

-2x + -2y = -228

2x + 5y = 351

3y = 123

y = 41

Since y is the amount of R5 coins, we know we have 41 R5 coins.

So the answer is

4 0
