<h2>Answer:</h2>

PART-A Perimeter= 24 in.

PART-B Area of inside frame=6×4=24 square inches.

2 in.×32 in.
4 in.×16 in.

4) Dimensions of outside frame= 12.5 ft×17.5 ft.

<h2>Step-by-step explanation:</h2>

PART-A

the outside frame has the measures as: 7 in. and 5 in.

i.e. the frame is in shape of a rectangle.

Perimeter of the outside edge= 7+7+5+5=14+10=24 in.

Hence, Perimeter= 24 in.

PART-B

Now we are asked to find the area of the inside of a frame as the frame is in the shape of a rectangle.

We know that the area of rectangle= l×b

where l represents the length of the frame and b represents the breadth of the rectangle.

Here we have l=6 in.

and b=4 in.

Hence, Area of inside frame=6×4=24 square inches.

Now we are given that the area of the frame was 64 inches².

So the possible dimensions could be:

2 in.×32 in.
4 in.×16 in.

Now we are using a scale factor as:

1 in.=2.5 ft.

the dimension of the outside frame was: 5 in.×7 in.

As 1 in.=2.5 ft.

5 in.=5×2.5=12.5 ft.

and 7 in.=7×2.5=17.5 ft.

Hence, the new dimension after using the scale factor is:

12.5 ft×17.5 ft.

Hey there,

Your question states: <span>Part A-Find the PERIMETER of the outside edges of the frame.

You will do 5+5+7+7 and you will get 24.

Your correct answer would be 24 ft
_____________________________________________________________

Your question states: </span><span>Find the AREA of the inside of the frame where the picture would belong and the area of the entire frame using the outside values. So I will basically do everything I did for (Part A) but I will do 25 x 35 and this would give me 875.

The area of the frame above would be 875 ft.
_____________________________________________________________

Your question states: </span><span>If the area of the frame was 64 inches², what would be 2 possible sets of dimensions that could be used to make a frame with that area?

You would do 64/4 because this is a square and a square has 4 sides. So I will do 64/4 and I will get 16.

16 will be your correct answer.
_____________________________________________________________

Your question states: </span><span>The frame is being enlarged to hang on a gallery wall. Using the scale factor of 1in=2.5ft., give the new dimensions of the outside edges of the frame.

</span>So if each each equals 2.5. I will do 2.5 x 5 and that will give me 12.5. I will also do the same on the other side because this is a square.So that means I will do 12.5+12.5 and I will get 25. Now for the number 7, I will do 7 x 2.5 and that will give me 17.5 but sense its a square I will do the same on the other side and I will get 35. So then I will add 25+35 and I will get 60.

The perimeter of the frame would be 60 ft.
_____________________________________________________________

Hope this helps your brain.

Answer:

A. Simon's unit rate is 2 more miles per hour than Eric's unit rate

Step-by-step explanation:

We are concerned with the number of miles each runs in 1 hour.

For Eric, that means x=1 in his equation, so his mileage is ...

y = 6×1 = 6 . . . . miles

For Simon, it means we want to find time = 1 hour on the horizontal axis at the bottom of the graph. Then we want to see where the graphed line crosses that vertical line. The point of crossing has horizontal line that goes over to 8 on the vertical distance axis. That is, Simon runs 8 miles in 1 hour.

Eric's unit rate (miles in 1 hour) is 6 miles per hour.

Simon's unit rate (miles in 1 hour) is 8 miles per hour.

Simon's unit rate is 2 more miles per hour than Eric's unit rate.

The weight of people in a small town in missouri is known to be normally distributed with a mean of 154 pounds and a standard de

ad-work [718]

If a random sample of 20 persons weighed 3,460, the sample mean x-bar would be 3460/20 = 173 pounds.
The z-score for 173 pounds is given by:
$z=\frac{173-154}{29}=0.655$
Referring to a standard normal distribution table, and using z = 0.66, we find:
$P(\bar x\ \textless \ 173)=0.7454$
Therefore
$P(\bar x\ \textgreater \ 173)=1-0.7454=0.2546$
The answer is: 0.2546

Mary O’Connell is earning a weekly salary of $521.60 as a payroll clerk. She has accepted a new assignment in the tax processing

docker41 [41]

Answer:

$ 65.59 more per week

Step-by-step explanation:

Assuming she worked <u>52</u> weeks a year as a clerk :

30534 - <u> 52</u> * 521.6 = $ 3410.80 more per year

now each WEEK that is 3410.80 / 52 = 65.59

(?,3) is on the line y=2x+5 what is the other coordinate

Dmitriy789 [7]

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Substitute it into the equation:

3 = 2x + 5

Subtract 5 from both sides:

-2 = 2x

Divide both sides by 2:

x = -1

The other coordinate is -1

Please help with the question 2 to 18

vladimir1956 [14]

Since these questions all require similar methods of solving, I will only completely work out the first question of each type.

2. To find $\frac{7}{10}$ as a decimal, all we need to do is complete the fraction by dividing the numerator by the denominator.

$\frac{7}{10}$ = 7 / 10 = 0.7

$\frac{7}{10}$ as a decimal is 0.7.

3. To write a fraction as a percentage, we must first convert it into a decimal, the way we did in problem 2.

$\frac{13}{20} =0.65$

Then to change that number into a percentage, we can either multiply it by 100, or (my personal shortcut) just shift the decimal point over two places to the right.

0.65 = 65%

which is the answer to question 3.
$\frac{13}{20}$ written as a percent is 65%.

4. Writing a percentage as a fraction is a bit easier than writing a fraction as a percentage. All you need to do is place the percentage in the numerator's place of a fraction with 100 as the denominator and simplify.

2%5 = $\frac{25}{100}$

Since 25 goes into 100 four times, we can simplify this fraction.

$\frac{25}{100} = \frac{1}{4}$

which is our answer.

25% written as a fraction is $\frac{1}{4}$ .

5. This is the same as problem 3, so I won't show my work for the sake of time.

$\frac{2}{5}$ as a percentage is 40%.

6. This is the same as problem 1, so I will not show steps again.

$\frac{3}{20}$ as a decimal is 0.15.

7. Done similar problems in past. No work shown.

$\frac{21}{50}$ as a percent is 42%.

8. Same as last problem.

$\frac{1}{25}$ as a percent is 4%.

9. Same as number 4.

6% as a fraction is $\frac{3}{50}$ .

10. Similar in past.

$\frac{3}{5}$ as a percentage is 60%.

11. Same as 6.

$\frac{12}{25}$ as a decimal is 0.48.

12. Done a lot of these so far.

$\frac{3}{10}$ as a percentage is 30%.

13. Just did one like this.

$\frac{3}{4}$ as a percentage is 75%.

14. Same as 4 and 9.

65% as a fraction is $\frac{13}{20}$ .

15. Plenty of these done in past.

$\frac{1}{5}$ as a percentage is 20%.

16. Last problem, and it's just like the one just before this.

$\frac{9}{10}$ written as a percent is 90%.

So there are the results.
Hope that helped! =)
