Answer 1

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)

Answer 2
18 dimes and 12 quarters ..........

Answers

Answer:

I believe that it would be better to use the second scale, or 1ft to 500ft.

Step-by-step explanation:

If you used the first scale(1in to 10ft) then you would have a 75in model, or 6.25ft, this would be to big to display on your desk. If you used the second then your model would be about 1.5in which all though is small it would be better for display.

Answer:

1 inch

Step-by-step explanation:

1 foot = 500 feet

1 inch = 10 feet

^ if you do 12 x 10 it equals 120, which is less than 1 foot = 500.

But, if you want it a big it would be 1 foot = 500.

    4/729  so 4 then /  then 729

Step-by-step explanation:

Your first term is 4 that is your starting point

Your common ratio is 1/3 so we will be multiplying by that

we will do this six times to get to the seventh term

so the second term is

4*1/3= 4/3

4/3 is our second term so we multiply it by 1/3 to get our third term

4/9 then fourth term is 4/9 *1/3

so 4/27

fifth should be 4/81

sixth should be 4/243

seventh should be 4/729

Answers

Answer:

144 or 72^2

Step-by-step explanation:

You have one leg a 5 and the other leg we don't know, well we know the hyponuse is a 13.

So the first step is

A^2 + B^2 = C^2

2 step,

5^2 + B^2 = 13^2

3 step

5 x 5 = 25 and 13 x 13 = 169

25 + B^2 = 169

4 step

169 - 25 = 144

144 divided by 2 is 72, so 72 x 72 is 144.

If you have an answer 72 squared or 144 both will work.

It does not help that you don't give the answers.

The answer would be 144. Hope this helps!!!!!
