Bob is filling his 7000-gallon swimming
pool. His hose fills at a rate of 22.2
gallons per minute. To the nearest
minute, how long will it take to fill his pool
Answers
Answer:
315 minutes
Step-by-step explanation:
To solve this, we must divide the gallons of the swimming pool by the rate of gallons per minute.
7,000 gallons divided by 22.2 minutes equals 315.3 minutes.
We can round this to 315.
315 minutes is how long it will take to fill the pool.
The length of a rectangle is six times its width.
If the area of the rectangle is 600 in, find its perimeter.
Answers
Answer:
140 in
Step-by-step explanation:
x = length
y = width
x = 6y
area = x × y = 600 in² (I hope you forgot to put the ² on the in and not your teacher).
perimeter = 2x + 2y
using the first equation as substitute in the second equation we get
6y × y = 600
6y² = 600
y² = 100
y = 10 in
x = 6y = 6×10 = 60 in
perimeter = 2×60 + 2×10 = 120 + 20 = 140 in
susie bought 4 hair bows for 0.50 each which equation shows how to find the total cost in dollars and cents of the hair bows bought
Answers
Hi! I'm happy to help!
We need to look for clues in the problem to see which operation we are going to use. We see the word each, which represents multiplication.
So, we will multiply 4 by 0.50 to get our cost.
4×0.5

So, the cost of the 4 hair bows is $2.00.

is a two digit number always less than a three digit number
Answers
Option C is correct. Whether a two-digit number is always less than a three-digit number depends on the first digit in the number.
A number can be a combination of a positive and negative integer. For example,
23 is a 2 positive digits number -231 is a 3 digits number (containing a negative and positive integer)We can see from the numbers that 23 (a two digits number ) is greater than -230 (a 3 digits number) which falsifies the claim that a two-digit number is always less than a three-digit number.
The veracity of the claim all depends on the first digits of the number (whether it is a positive or negative integer)

If XR is (2x + 5) inches long and RY is 22 inches long, what
is the value of x? What about XR? What about XY?
helpp
Answers
The value of x is 8.5 inches
The value of XR is 22 inches
The value of XY is 44 inches
If R is the midpoint between X and Y, it means that the length of /XR/ and /RY/ are equal
If /RY/ = 22, then /XR/ = 22 also
XR = (2x + 5) = 22
To determine the value of x , combine similar terms
2x = 22 - 5
2x = 17
x = 8.5 inches
The value of XR = 22 inches
Value of XY = 22 + 22 = 44 inches

Answer:
∠1 = 64°
∠2 = 116°
Step-by-step explanation:
Let x = supplement and x + 52 = the one angle. Set up this equation:
(x) + (x + 52) = 180
2x + 52 = 180
Subtract 52 from both sides.
2x = 128
Divide both sides by 2, and you get x = 64.
Keep in mind this equals the supplement. To find the measure of the other angle, add 52 and you get 116
Referring to the figure, find m∠1

Answer:
(x+x)^2=4-x
Step-by-step explanation:
I think, don't be mad if I'm wrong!
The approach used seems to be:
Step 1: Make the first term x^2 not 2x^2, by dividing every term by 2.
x^2 + 1/2 x - 2=0
Note here that because the computer had “+” before the second box in the first line, you needed to put “-2” instead of 2 to keep the sign correct.
Step 2: Move that -2 to the other side and then figure out what you’re going to add to the right side to complete the square. The way you do this is you take the “b” value from “bx” and divide it by 2 and square it.
Divide b by 2: 1/2 ÷ 2 = 1/2 • 1/2 = 1/4
Square that: (1/4)^2 = 1/16
So you need to add 1/16 to both sides.
The final step is to factor the left side and add the numbers on the right side.
Left side: x^2 + 1/2x + 1/16 = (x+1/4)^2.
The 1/4 can be found either by dividing the “b” by 2 or taking the square root of 1/16. Both give you 1/4.
You can always double check your work by FOILing out (x+1/4)^2 as (x+1/4)(x+1/4) and making sure you get used 1/4 correctly.
On the right side, 2 + 1/4 = 2/1 + 1/4 = 8/4 + 1/4 = 9/4
You need to find a common denominator to add them.
The above process will always work. How messy it is totally depends on the numbers involved.
