Find the perimeter of a rectangular swimming pool that measures 12 feet by 22 feet.

The perimeter is 78ft. You do 12 times 2 plus 22 time 2 because a rectangle has 2 sets of equal sides.

If you estimate it the equation is -10+12=9+12=21 or 2=21=21 so the answer is false

In 4 years, harry’s age will be the same as jim’s age is now. in 2 years, jim will be twice as old as harry will be. find their ages now.

The answer to this question would be:
Jim     =6 years
Harry =2 years

To answer this question, you need to translate the description into a  mathematical equation. If H= Harry's ages and J= Jim's ages, then the equation should be look like this:

1. H+4= J
2. (J+2)= 2(H+2)
     J+2= 2H+4
     J= 2H +2

If you put the 1st and 2nd equation together, the result would be:
H+4= J
H+4= (2H +2)
H-2H= 2-4
-H= -2
H=2

After that insert the H value to either 1st or 2nd equation.
H+4= J
2+4=J
J= 6

Decide whether the following rates are equivalent. 12 pages in 20 minutes or 20 pages in 32 minutes

The two fractions that we can extract from the given rates above are:
                (1) 12 pages / 20 minutes
                (2) 20 pages / 32 minutes
We can reduce the fractions or rates to their lowest term by dividing the numbers by 4 such that,
                 (1) 3 pages / 5 minutes
                 (2) 5 pages / 8 minutes
Therefore, the rates are not equivalent.

Find the range of the function y=-5x-7

Range is how far up or down the garph can go
basically the limits of y

find min and max of y

basically find the biggestor smallest the x can get to influence y
confusing sorry
when x is an even number, that number is still negative


so make that number as small as possible
if x=(big number that is negative)
we get -1/(5^(big number)) which basically makes it nigligible or almost 0

y=-7 is max


when x=big number (positive) we get very negative number

so range is from negative infinity to -7
basically y<-7
we choose < and not ≤ because the -5ˣ will never dissapear, it will just be very, very small


y<-7 is answer

Two sides of a triangle measure 5 in. and 12 in. Which could be the length of the third side? 3 in. 6 in. 10 in. 18 in.

Answer:

The possible answer is 10 in.

Step-by-step explanation:

Two sides of a triangle measure 5 in. and 12 in.

If three side of triangle are a, b and c then sum of two side is always greater than third side.

Sum of two side greater than third side.  

a+b>c

a+c>b

b+c>a

Difference of two side is less than third side.

a-b<c

b-c<a

a-c<b

Here, we are given two sides of a triangle 5 in and 12 in.

Possible length of third side be

12-5 < c < 12+5

7<c<17

Third side must be lie between 7 to 17.

According to option, Third side must be equal to 10 in.

Hence, The possible answer is 10 in.
