Answer:

The rate (in feet per/second) of the skydiver's drop is 30 feet/second

Step-by-step explanation:

To solve this problem let us itemized our given data

Given data

Distance of drop or height s =450 ft

Time taken to drop t = 15 sec

The rate of drop also speed/velocity v=?

We know that the

velocity v= distance travel/time

Substituting our data we have

v= 450/15=

v = 30 feet/second

Answer:

30feet/second

Step-by-step explanation:

The rate in feet per seconds of the diver will be the speed of the diver.

Speed is the rate of change in distance of a body.

Speed = Distance/Time

Given distance or height of drop = 450feet

Time = 15seconds

Rate of change in distance = 450/15

Rate of change in distance = 30feet/second

Answer:

43.13 = 5.25h + 9

Step-by-step explanation:

Let's solve this by making an equation.

$9 for the helmet, and $5.25 per hour.

h will stand for hours, C will stand for Amanda's cost.

C = 5.25h + 9

Now, substitute in what we learned from the problem.

43.13 = 5.25h + 9

This is an equation you can use to solve for the hours.

CAN SOMEONE PLZzzz Plzzzz HELP!!!???

First plot the points. Let’s just use the first graph. When you have done that. Draw a triangle. Find the right angle and look at what line is across from that. That is the hypotenuse. That is the length that you are trying to find. So you have to do your equation: a^2 + b^2 = c^2. A and B have to be the length of the other 2 lines(just count it). When you have done that repack you a and b with your #s. And what ever is equal to you c. Then that is you answer. (Im sorry if this was confusing)

Write a system of equations that could be used to solve the situation described below.
attashe74 [19]

If there are 12 coins under the couch and every coin is either a nickel or a penny and together they are forming 32 cents then the equations which represent the problem will be x+y=12, 0.01x+0.05y=0.32. The correct option is B which is x+y=12, 0.01x+0.05y=0.32.

Given There are 12 coins and total money is 32 cents.

Let the number of pennies be x and the number of  nickels be y.

According to question there are 12 coins so the first equation becomes:

x+y=12.

Then we have been told that together they amount to 32 cents.

We know that 1 penny is 1 cent coin and 1 nickel is 5 cent coin so the equation becomes :

1*x+5*x=32

x+5y=32

converting into dollar

0.01x+0.05y=0.32.

Hence the right equations showing the problem of nickel and pennies are x+y=12, 0.01x+0.05y=0.32.
