Originally your racecar weighed 3000 pounds and with the weight reduction, your car now weighs 2700 which is 1 ton and 700 pounds

1 him is 2000 pounds.
1.5 tons is 3000 pounds.
Because the carbon fiber reduced the weight by Rio pounds, you have the equation 3000-300=2700 pounds and 1 7/20

A general contractor is constructing a building that requires a concrete foundation that is to be 20 feet by 22 feet and 24 inch
ad-work [718]

Answer:

$38427

Step-by-step explanation:

Surface Area Formula: A=2(wl+hl+hw) where l=length w=width h=height

A=2((20(22))+(22(2))+(20(2)) = 1048ft^2

3 ft = 1yds -> 1048 ft = 349 1/3 yds

349 1/3(110)= 38426.66666

Lily has $2. 75 in her pocket, consisting of dimes and quarters. If there are 17 coins in all, how many of each does she have?.
Nikitich [7]

Answer:

Lily has 7 Quarters and 10 Dimes

Step-by-step explanation:

Let's use pennies instead of $.

Let <u>D</u> and <u>Q</u> stand for the numbers of Dimes and Quarters, respectively.

We are told that there are 17 coins total:

  <u> D + Q = 17</u>

We also learn that they amount to 275 (pennies).  We can write that as:

<u>10D + 25Q = 275</u>  [Each D is worth 10 pennies, etc.]

We have two equations and two unknowns.  We can rearrange one equation to find the value of either of the unknowns, and then use that it the second equation.

I'll rearrange the first:  

 D + Q = 17

<u>   D = 17 - Q</u>

Now use this value of D in the second equation:

10D + 25Q = 275

10(17-Q) + 25Q = 275

170 - 10Q + 25 Q = 275

15Q = 105

<u>Q = 7  :  7 Quarters.</u>

<u></u>

Since D + Q = 17:

D + 7 = 17

<u>D = 10 Dimes</u>

==========================================

Let's check these results:

Q = 7 Quarters

D = 10 Dimes

1.  Is this 17 coins in total?  (7+10 = 17)  <u>YES</u>

2.  Does this add to $2.75?  (10*10) + (7*25) = 275 cents?

 (100 + 176) = 275 (cents)   <u>YES</u>

============================
