the perimeter of a rectangular pool is 258 m. If the width of the pool is 52 m, what is its length?
Answer:77 is the length
Step-by-step explanation:52m times 2 =104 104-258=154 divided by 2 =77
Answer:
77
Step-by-step explanation:
Since the two widths is 52+52=104, then subtract that from the total perimeter, 258-104=154, and divide it by two to get the answer, 154/2=77.

The coordinate grid shows points A through K. What point is a solution to the system of inequalities? y < −2x + 10 y < 1 over 2x − 2 coordinate grid with plotted ordered pairs, point A at negative 5, 4 point B at 4, 7 point C at negative 2, 7 point D at negative 7, 1 point E at 4, negative 2 point F at 1, negative 6 point G at negative 3, negative 10 point H at negative 4, negative 4 point I at 9, 3 point J at 7, negative 4 and point K at 2, 3 I B A F
Answer:
I think that it could be A, or the third choice.
We need to see which points are solutions for the given system of inequalities, thus the solutions are points B and L.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Solving a system of inequalities we have the system here;
y <-2x + 10
y < 1/(2x - 2)
A point is a solution of the system if and only if it is a solution for both inequalities.
Now, Shade the region below the like for x = 5.
y = -2(5) + 10
= -10 + 10
= 0
For x= 0
y = -2(0) + 10
= 0 + 10
= (0, 10)
The diagram is attached below.
So, only B and L are solutions for the system.

Do you think that students should be proficient in addition before learning multiplication?
answer in 175 words! thank you so much :)
Answer:
Yes students should be confident in addition before they proceed to mulplication.This is because addition is the base of multiplication and requires mastery before you start,so It would be much easier to solve

Answer:
15 3/4
Step-by-step explanation:
8+7=15
1/2+1/4= 3/4
15+3/4
Answer:
15 3/4
Step-by-step explanation:
You need to have like denominators before you add so you need to find the LCM (least common multiple) of the two numbers. Then you have to find how much you have to multiply each number by to get the multiple. Then you just have to remember that whatever you do to the bottom you do to the top.
1. 8 1/2 + 7 1/4 This is your equation.
2. 8 2/4 + 7 1/4 The LCM of 2 and 4 is 4. You multiply by two in the bottom to get 4 so you multiply by 2 at the top. (This is talking about the first fraction).
3. 15 3/4 Then you just add as you would normally add without changing the denominators an simplifying if you need to. (You don't need to simplify for this equation).

You never scale down to write a complex rate as a unit rate. True or false?
Answer:
True
Step-by-step explanation:
We should use simple units while doing any type of calculation, using simple units make it easy for other people to kn ow the calculation, on the contrary if we use complex units then it will make the calculation more complicated thereby increasing the chances of mistake.

Answer:
-19/3
3x-1/4 = -5
3/4x + -1/4 = -5

1x = -19/4
multiply both sides by 4/3
x = -19/3
What is the greatest perfect square that is a factor of 392
Answer:
The factor of 392 is 36.
The greatest perfect square that is a factor of 392 is 14.
Given,
392
We need to find the greatest perfect square which is a factor of 392.
What is a factor of a number?Example:
2 x 4 = 6
2 and 4 are factors of 6.
Find the factor of 392.
Possible factors are:
4 x 98 = 392
49 x 8 = 392
196 x 2 = 392
We see that,
4, 196, and 49 are perfect squares.
2 x 2 = 4
14 x 14 = 196
7 x 7 = 49
14 is the greatest perfect square.
Thus the greatest perfect square that is a factor of 392 is 14.

A box contains one each of $1, $5, $10, $20, and $100 bills. It costs $14 to reach in and withdraw one bill. What is the expected value?
Answer:
13.20
Step-by-step explanation:
1/5 (1+5+10+20+100) - 14
The required expected value is 13.20.
A box contains bill of = $1, $5, $10, $20, and $100
It costs $14 to reach in and withdraw one bill.
Its estimated value of the variable in probability.
Expected value= mean - 14
= (1+5+10+20+100)/5 -14
= 13.20
Thus, the required expected value is 13.20.

Answer:
c = 13
Step-by-step explanation:
c = 6(3) - 5
c = 13
Answer:
C. c=13
Step-by-step explanation:
This is how I figured it out:
1. I took the equation (c=6a-b) and I replaced the letters with the numbers given. (a=3 & b=5) so I got the new equation c=6(3)-5.
2. I used PEMDAS (parentheses, exponents, multiplication, division, addition and subtraction. Since we have multiplication and subtraction needed multiplication is shown before subtraction in PEMDAS so we would figure out 6(3) first which is equal to 18.
3. Now we have the new equation of c=18-5. Since subtraction is left we would take away 5 from 18 and now we have the final answer of 13. So the equation would now look like this: c=13. It's pretty obvious that c=13 that c has the value of 13.
