Answer:
The perimeter of the spiral notebook is 14 inches
Step-by-step explanation:
The given parameters are;
The area of the rectangular binder cover, Aₓ = 80 in²
The area of the rectangular binder cover = 8 × The area of the spiral notebook, Aₙ
The length, l of the spiral notebook = 5 inches
Let w represent the width of the spiral notebook cover;
We have;
Aₙ = l × w = 5 × w
Aₓ = 80 = 8 × Aₙ
8 × Aₙ = 80
∴ 8 × 5 × w = 80
w = 80/(8 × 5) = 80/40 = 2
w - 2 inches
The perimeter, P, of a rectangle = 2 × length, l + 2 × width, w
∴ For the spiral notebook, we have, [tex]P_{Spiral \ notebook}[/tex] = 2 × 5 + 2 × 2 = 14
The perimeter of the spiral notebook, [tex]P_{Spiral \ notebook}[/tex] = 14 inches.

b. when will the plant be at a height of 20 cm?
Answer:
30 cm
Step-by-step explanation:
A. Multiply daily rate by number of days and add that to the starting height:
Height = 2d + 8
B. Set height to 20 and solve for d:
20 = 2d +8
Subtract 8 from both sides
12 = 2d
Divide both sides by 2
D = 6
It wall take 6 days.

What is unit conversion?Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.
Unit conversion is a multi-step procedure that involves adding, subtracting, multiplying, or dividing by a conversion factor. Additionally, rounding and choosing the appropriate number of significant digits may be necessary during the process. To measure various parameters, various units of conversion are utilized.
Given that the radius of the moon is approximately 1,350,000 m. The radius in kilometers will be calculated as,
1 km = 1000m
1 m = 1 / 1000 km
1350000 meters = 1350000 / 1000 km
1350000 meters = 1350 km

The regular price of a swimsuit in the junior department of a store is $54. The store advertises an end-of-season sale at 40% off the regular price of all swimsuits. Two weeks later the store advertises a bonus sale at an additional 1/5 off the end-of-season sale price of all swimsuits. Shannon and Mary decide this is a great time to shop for swimsuits. Shannon figures that the swimsuits are now 60% off the regular price. Mary disagrees, because she figures that the total discount is actually less than 60%.
a. What is the cost of a swimsuit during the end-of-season sale? Justify your reasoning using a model.
b. What is the cost of a swimsuit during the additional 1/5-off bonus sale? How can you show this with a model?
c. Did Shannon or Mary figure the discount correctly? Use a model to explain.

Paul Smith pays $50.00 a month for group health insurance. There is a $300 deductible. His medical bills for the last year were $2,600.00. Paul’s insurance company provided payment of 80% of the bills less the deductible. What was Paul’s total cost (including the monthly premium)?
Answer:
$1,360
Step-by-step explanation:
Take the monthly payment of $50 and multiply it by 12 because there is 12 months in a year which is $600. Next subtract $2,600 by your deduction of $300 which is $2,300. Then multiply by 20% because the insurance pays 80% leaving you with 20%, you get $460. Add $460 and $300 because those are the amounts you paid and you get $760. Now add the $600 to the $760 because of the monthly payment. The total comes out to $1,360.

Given:15y+7=12-20y prove:y=1/7 (I just need the prove thanks)
Answer:
15y+7=12-20y (add 20y to both sides)
35y+7=12 (minus 7 from both sides)
35y = 5 (divide both sides by 35) (5/35=1/7)
y= 1/7
Answer:
64/7 = 64/7 yes y = 1/7
Step-by-step explanation:
To prove this we simply have to plug in!
15(1/7) + 7 = 12 - 20(1/7) (simplify)
15/7 + 7 = 12 - 20/7 (simplify further)
64/7 = 64/7
So yes y = 1/7
