Answers

He would get a profit of 64.09
64.09 or 64% because if you subtract 152.99 from 88.90 you get 64.09 and you round it to 64% because the 0 is under 5 so you lower it

Sam drew a rectangle measuring 9 feet in length by 15 feet in width. If she wants to make a similar rectangle measuring 27 feet in length, what should the width be?

Answers

Answer:

45

Step-by-step explanation:

If sam made a rectangle 9 feet in length and 15 in width. And we already know the next rectangle is 27 feet we can divide it by 9.

27/9=3

Now that we know its 3x the normal size we can grab the 15 and multiply it by 3.

15x3=45

in short: the answer is 45

Luke Bryan said the following expressions are equivalent because of the
Distributive Property. Is he correct?
2( 2x2+ 6) = 2x2+ 1

Answers

Luke is not correct

You need to do the problem in order of PEMDAS, so start with parentheses

2 x 2 = 4 + 6 = 10
Distribute the 2 on the outside
2 x 10 = 20

On the other side of the equation start with multiplication

2 x 2 = 4 + 1 = 5

5 ≠ 10

Luke is not correct

Jake and Finn both worked hard over the summer. Together they earned a total of $400. Finn earned $25 more than Jake.
(a) Graph the equations in the system.
(b) Use your graph to estimate how much each person earned. How much did each person earn?

Answers

Answer:

F = 212.5  

J = 187.5

My way is weird but i divided each side by 2 and subtracted 25 from jake and added 25 to finn. Then distributed 25 for each.

ex: 175 + 12.5 = 187.5.

225 - 12.5 = 212.5.

Add them both and you get 400.

Answers

Answer:

18 dimes, 12 quarters

Step-by-step explanation:

We are to solve the system of linear equations for D and Q, where D is the number of dimes and Q is the number of quarters.

Each dime is worth $0.10 and each quarter $0.25.  Thus, D dimes are worth ($0.25/dime)D and Q quarters ($0.25/quarter)Q.

The sum of D and Q comes out to 30 coins, a mixture of dimes and quarters:  D + Q = 30, so Q = 30 - D.  

Now let's solve this equation:  ($0.10/dime)D + ($0.25/quarter)Q = $4.80.

Substitute 30 - D for Q:

($0.10/dime)D + ($0.25/quarter)(30 - D) = $4.80

This is now entirely in D (no Q shows up).  Performing the indicated multiplication, we get 0.10D + 0.25(30) - 0.25D = 4.80

Combining like terms:  0.10D - 0.25D = -0.15D, and -7.5 + 4.80 = -2.7

Thus, -0.15D = -2.70, and so D = 2.70/0.15 = 18 (There are 18 dimes.)

Since Q = 30 - D, and D - 18, Q = 30 - 18 = 12 (There are 12 quarters)

18 dimes and 12 quarters ..........
