$24.50 is your original amount, and you know you have a 20% added to that. So, you can multiply the money by the percentage:

24.5 x 1.2 (we multiply it by 1.2 because we want the tip PLUS the original amount)
= 29.4

So the answer is the first choice, $29.40

After you get 1.2 you have to multiply it by 24.50 and you should get 29.50

erma4kov [3.2K]

In first 40 hours he earns = 7.30 x 40 = $292
Each hour after his rate = 7.20 x 1.5 = $10.80 per hour
In extra four hours he earns = 10.80 x 4 = $43.20

Total earnings = $292 + $43.20 = $335.20

Answer:

the awnser is 30

Step-by-step explanation:

mario and peach equal the same, so you would have to do 36÷3 and that equals 12, so then you look at mario divided by toad, and you would do 12÷2 to get 6, so toad would be 6, and that make bowser 0. so it would be 12+0+12+6=30

Whoever responds first will get marked best!!!!!The Garcia family is driving from 3,272 miles from San Diego, CA ot Bar Harbor,

mojhsa [17]

Answer:

Step-by-step explanation:

We know that in 5 days they have travelled 2045 miles. This means that their per day average for travel is 2045/5=409 miles per day.

Now the distance left is 3272-2045=1227 miles.

And if we divide the average miles with the miles left, it gives us= 1227/409

So, the total time taken for travel will be= 5+3=8 days

I guess this is the way to do it.

Find a formula for the described function. A rectangle has perimeter 16 m. Express the area A of the rectangle as a function of

Alex17521 [72]

Part A:

Let the length of one of the sides of the rectangle be L, then the length of the other side is obtained as follow.

Let the length of the other side be x, then

$2(L+x)=16 \\ \\ \Rightarrow L+x=8 \\ \\ \Rightarrow x=8-L$

Thus, if the length of one of the side is x, the length of the other side is 8 - L.

Hence, the area of the rectangle in terms of L is given by

$L(8 - L) = 8L-L^2$

Part B:

To find the domain of A

Recall that the domain of a function is the set of values which can be assumed by the independent variable. In this case, the domain is the set of values that L can take.

Notice that the length of a side of a rectangle cannot be negative or 0, thus L cannot be 8 as 8 - 8 = 0 or any number greater than 8.

Hence the domain of the area are the set of values between 0 and 8 not inclusive.

Therefore,

$dom(Area)=0\ \textless \ L\ \textless \ 8 \ or \ (0, 8)$
