I arrive home to find that my 55 foot by 35 foot basement has 18 inches of water in it.

a) If 1 cubic foot of water is about 7.48 gallons, how much water will I be pumping out of my basement?
Express your answer rounded to the nearest tenth of a gallon.
gallons

Answers

To find the volume of water in cubic feet, you would multiply length x width x height. All the measurements need to be in the same units, so multiply 18 inches x 12 inches/foot = 1.5 feet. Then to find volume, multiply 55 feet x 35 feet x 1.5 feet = 2887.5 cubic feet of water. To convert cubic feet to gallons, multiply by 7.48. 2887.5 x 7.48 = 21598.5 gallons, rounded to the nearest tenth of a gallon.

Hey square piano has an area of 200 ft.² how long is each side of the piano to the nearest 0.05

Answers

since all sides of the square are equal, therefore area of square can be calculated using the following rule:
area of square = side^2
200 = (side length)^2
therefore,
the length of each side is sqrt(200) = 14.14 ft

Answer: 6.121212121212... = 202/33

Step-by-step explanation:

(612 - 6)/99 = 606/99 = 202/33 = 6.12121212121212... ∈ ℚ

In mathematics, a rational number is any number that can be expressed as the quotient or fraction of two integers, a numerator and a non-zero denominator.  

Since 6.121212121212... is a number whose digits are periodic (12) , we can express it as a fraction 202/33, therefore is a rational number ∈ℚ.

Answers

100,000.......Please mark brainliest....
Hello! 1,995,298 rounded to the nearest ten thousands would be 2 million. 9 is in the ten thousands digit, so to find whether we round or not, you have to look at the next number to the right. In this case, it’s a 5, and when the number is 5 or higher, you go up. When you go up, if simply rounds to 2 million, not only because of that, but the 9 digit is also in the hundred thousands place. The answer is 2,000,000.

ABD is the supplement of DBC, so it is equal to 180-130= 50 degrees.

If BE is the bisector, then it splits the angle in half evenly. 50/2=25 degrees for EBA and DBE each.

Final answer: 25 degrees
Becuase this is a straight angle, we know that the total amount of the degrees adds up to 180. We can write an equation to help solve for Angle  EBA
(180-130)/2=x
This is because we know angle DBC is 130, so when that 's subtracted from the original amount we are left with 50 degrees for angle ABD. Then, since EB goes through the middle of it, we know that Both ABE and EBD are equal to half of 50 which is 25.

Therefore, <EBA is equal to 25 degrees

Tom performed a total of 100 hours of community service. He served at three charities- Salvation Army, Red Cross and Rescue Missiom. The number of hours he served at the Red Cross was 19 hours more than at the Salvation Army. The number of hours he served at the Rescue Mission was 8 hours more than what he served at the Red Cross

Answers

Let x, y, z be the number of hours that Tom spent in service in Salvation Army, Red Cross, and Rescue Mission, respectively. From the statement above, the sum of the numbers should be 100. 
           x + y + z = 100

The equations that can be derived from the given and the assigned variables,
    y = x + 19
    z = y + 8

Expressing the times in terms of variable x,
   y = x + 19
   z = (x + 19) + 8 = x + 27

Solving for the value of x,
              x + (x + 19) + (x + 27) = 100

The value of x from the equation is 18. 

   y = 18 + 19 = 37
   z = 18 + 27 = 45

The number of hours he spent in three charities are 18, 37, and 45, respectively. 

Tom volunteered 18 hours at the Salvation Army, 37 hours at the Red Cross, and 45 hours at the Rescue Mission.

Let S represent the number of hours Tom served at the Salvation Army.

The number of hours at the Red Cross is 19 hours more than at the Salvation Army,
R = S + 19.The number of hours at the Rescue Mission is 8 hours more than what he served at the Red Cross,
M = R + 8.

Since the total number of hours Tom served is 100, we have,

S + R + M = 100

Substitute R and M with the expressions in terms of S:

S + (S + 19) + (S + 19 + 8) = 100

S + S + 19 + S + 27 = 100
3S + 46 = 100
3S = 54
S = 18

So, Tom served 18 hours at the Salvation Army. Now, we find the hours for the other two charities,

R = S + 19
= 18 + 19
= 37 hours at the Red Cross.M = R + 8
= 37 + 8
= 45 hours at the Rescue Mission.

In summary, Tom volunteered 18 hours at the Salvation Army, 37 hours at the Red Cross, and 45 hours at the Rescue Mission.

Complete question-
Tom performed a total of 100 hours of community service. He served at three charities – Salvation Army, Red Cross and Rescue Mission. The number of hours he served at the Red Cross was 19 hours more than at the Salvation Army. The number of hours he served at the Rescue Mission was 8 hours more than what he served at the Red Cross. Find the number of hours he volunteered at each charity.

Answers

y=−5/8 which is the answer to the equation 
 To check plug in the y value and see if it equals out
This is your problem: y-4y-3=5y+2. First, take y-4y and turn it in to -3y. Next, take 5y and put -5y instead. So your problem is looking like this so far: -3y-5y-3=2. Then, change -3 and turn it into a positive 3 at the end of the equation like this. -3y-5y=2+3. Then lets do -3y-5y which is -8y. Next, do 2+3 which is 5. Your problem looks like this -8y=5. Lastly, divide both sides of the equation by -8. Which means Y= -5/8.  Hope this helps ;)

What is the value of b? ​ 0.4 (3b + 10) = 19 ​

Enter your answer in the box.

Answers

The value of b = 12.5.

In order to get this answer, we must:
First, simplify both sides of the equation.
0.4(3b + 10) = 19
(0.4)(3b) + (0.4)(10) = 19 (Distribute)
1.2b + 4 = 19
Next, we must subtract 4 from both sides.
1.2b + 4 - 4 = 19 - 4
1.2b = 15
Last, we must divide both sides by 1.2.
1.2b/1.2 = 15/1.2
Answer: b = 12.5

I hope this helps! :>

0.4(3b +10) = 19

1.2b + 4 = 19

1.2b = 15

b = 15 / 1.2

A company produces a set of blocks. It costs them $5 to make. They mark it up 300% when they sell it to a toy distributor. The toy distributor marks it up an additional 150% when they sell it to a local toy store. The local toy store marks it up in additional 200%. They have a 30% off sale. You also have a coupon for an additional 15% off. Sales tax is 8%. How much did you pay for the set of blocks?

Answers

Hello! So, the toy company makes blocks that cost $5 to make. Then, they mark it up by 300%, which is marking the price up by 4. 100% markup is doubling the price, 200% is tripling the price, and 300% marks the price up by 4. Then, the blocks would cost $20. After that, the price would be marked up by 150%, so that’s 2.5 times the price of the original. When you do $20 by 2.5, then the blocks cost $50. The local toy store will mark the block up by 200%, which as said before, is tripling the price. Then, you do 50 * 3, and then the price of the blocks is $150. Then, it gets marked off by 30% and 10% of 150 is 15, so 30% off 150 is 45. When you do 150 - 45, the difference is $105. Then, you take off an additional 15%, But you would still have to pay 85% of the original price. You would do 105 * 0.85, and then you would get $89.25 for the blocks. But that’s not all. You have to pay 8% sales tax for the blocks. You can find the tax by doing 89.25 * 0.08 and then adding the prices together. Or, you can do 89.25 * 1.08 to find the total price. Either way, the product should be 96.39. The total price you paid for the blocks is $96.39.

Cody made deposits of $45, $18, and $27 into his checking account. He then wrote checks for $21 and $93. Write an expression to show the change in Cody's account. Then simplify the expression. ((This is integers and rational numbers I really need help with this!))

Answers

C = 45 + 18 + 27 - 21 - 93 C = -24 Let's use the variable C to represent the change in the balance in Cody's checking account. The easiest way to make the expression is to simply apply the additions and subtractions directly. So let's start with C C "Cody made deposits of $45, $18, and $27 into his checking account." C = 45 + 18 + 27 "He then wrote checks for $21 and $93." C = 45 + 18 + 27 - 21 - 93 So the expression to represent the change to Cody's checking account is C = 45 + 18 + 27 - 21 - 93 Now to simplify it. All you need to do is combine terms together. How far you go is up to you. So let's do it. C = 45 + 18 + 27 - 21 - 93 I'll add together all the deposits. C = (45 + 18 + 27) - 21 - 93 C = 90 - 21 - 93 And I'll combine the checks. C = 90 - 114 So now you can tell at a glance that Cody deposited $90 and wrote checks for $114. But we can make it simpler and combine those as well. So C = -24 And this tells you that Cody's checking account balance is now $24 lower than it was before he started making deposits and writing checks.

Answer:

-24
