The perimeter of a rectangle is 60 meters.if the length of the rectangle is 14 meters.what is the width of the rectangle?
Answers
We know that the formula for perimeter of a rectangle is:
P = 2l + 2w
We've been given enough information to solve this question!
The perimeter of the rectangle is 60 metres, and the its length is 14 meters long.
We must multiply the length by 2 and then subtract it from the perimeter to find the width.
W = P - 2l
W = 60 - 2(14)
W = 32
Therefore, the width of the rectangle is 32 metres long.
Final answer:
To find the width of a rectangle given its length and perimeter, apply the formula for the perimeter of a rectangle and solve for the width.
Explanation:
The width of the rectangle can be found by using the formula for the perimeter of a rectangle:
P = 2(length + width)
Given that the length is 14 meters and the perimeter is 60 meters, you can substitute these values to find the width.
60 = 2(14 + width)
60 = 28 + 2w
2w = 32
w = 16
Therefore, the width of the rectangle is 16 meters.

The ratio of lipsticks to eyeshadow is 1:9. The ratio of eyeshadow to mascara is 3:2. Given I have 3 more eyeshadows than mascaras how many lipsticks do i have?
Answers
We can find L using [tex]\( L = \frac{1}{9}E \)[/tex]:
[tex]\[ L = \frac{1}{9} \times 9 = 1 \][/tex]
So, you have 1 lipstick.
To solve this problem, we'll work step by step.
Let's denote:
- L as the number of lipsticks.
- E as the number of eyeshadows.
- M as the number of mascaras.
Given:
1. The ratio of lipsticks to eyeshadows is 1:9, which means L:E = 1:9 .
2. The ratio of eyeshadow to mascara is 3:2, which means E:M = 3:2 .
3. You have 3 more eyeshadows than mascaras, so E = M + 3.
First, we'll use the information to establish the relationship between L, E, and M.
From the ratio L:E = 1:9, we can express L in terms of E:
[tex]\[ L = \frac{1}{9}E \][/tex]
From the ratio E:M = 3:2, we can express M in terms of E:
[tex]\[ M = \frac{2}{3}E \][/tex]
Now, we can substitute E = M + 3 into the equation for M:
[tex]\[ M = \frac{2}{3}(M + 3) \][/tex]
3M = 2(M + 3)
3M = 2M + 6
M = 6
Now that we have found M, we can find E using E = M + 3:
E = 6 + 3 = 9
Now that we have found E, we can find L using [tex]\( L = \frac{1}{9}E \)[/tex]:
[tex]\[ L = \frac{1}{9} \times 9 = 1 \][/tex]
So, you have 1 lipstick.
The cost of going to the big playland park for a family is given by C = 15x + 50, where C represents the cost and x represents the number of family members. How many family members went if it cost them $125?
Answers
C = 15x + 50; C represents the total cost, and X represents the number of family members.
The total cost was $125, so we should substitute C with 125.
125 = 15x + 50; now, all we have to do is solve for x with basic algebra.
First, let's isolate the variable, so subtract 50 from both sides of the equation.
15x = 75; divide both sides by 15 to solve for x, the number of family members that went to the park.
15x / 15 = x
75 / 15 =5
We are left with the following solution:
x = 5
We can conclude that 5 family members went to the park.

Last year, a property manager bought five identical snow shovels and six identical bags of salt. The total cost of the snow shovels was $172.50, before tax and each bag of salt cost $6.20, before tax.
This year, the property manager bought two identical snow shovels and four identical bags of salt. The total cost of the snow shovels was $70.38, before tax, and the total cost of the bags of salt was $26.04, before tax.
Determine the item with the greatest percent increase in the rice from last year to this year. Be sure to include to the precent increase of this item to the nearest percent.
Answers
5h = 172.50 (5 shovels totaled $172.50)
Divide both sides by 5:
5h/5 = 172.50/5
h = 34.50
Last year, each shovel was $34.50.
Each bag of salt last year was $6.20.
This year:
2h = 70.38 (2 shovels totaled $70.38)
Divide each side by 2:
2h/2 = 70.38/2
h = 35.19
Let a be the cost of a bag of salt.
4a = 26.04 (4 bags of salt totaled $26.04)
Divide both sides by 4:
4a/4 = 26.04/4
a = 6.51
This year, shovels cost $35.19 each and bags of salt cost $6.51 each.
To find the percent increase in shovels, first find the amount of increase:
35.19 (this year) - 34.50 (last year) = 0.69 increase
Divide the amount of increase by the original amount:
0.69/34.50 = 0.02
There was a 2% increase in shovel costs.
To find the percent increase in salt, first find the amount of increase:
6.51 (this year) - 6.20 (last year) = 0.31 increase
Divide the amount of increase by the original amount:
0.31/6.20 = 0.05
There was a 5% increase in salt costs. The salt had a higher percent of increase.
The item with the greatest percent increase in price from last year to this year is the bag of salt, with a 5% increase.
The item with the greatest percent increase in price from last year to this year is the bag of salt, with a 5% increase, compared to the 2% increase for the snow shovels.
To determine the item with the greatest percent increase in price from last year to this year, we need to calculate the price per unit for each item both years and compare the percentage increases. Last year, the property manager bought five snow shovels for $172.50, meaning each shovel costs $34.50 ($172.50 \/ 5). This year, two snow shovels cost $70.38, so each costs $35.19 ($70.38 \/ 2). To find the percent increase for the snow shovels, we subtract last year's price from this year's price, divide by last year's price, and multiply by 100: (($35.19 - $34.50) \/ $34.50) \times 100 = 2% (rounded to the nearest percent).
For the bags of salt, each cost $6.20 last year. This year, the total cost for four bags was $26.04, so each costs $6.51 ($26.04 \/ 4). Using the same formula for percent increase, we get the percent increase for the bags of salt: (($6.51 - $6.20) \/ $6.20) \times 100 = 5% (rounded to the nearest percent).
Therefore, the item with the greatest percent increase in price from last year to this year is the bag of salt, with a 5% increase.

Hope I helped you,

An exponential number is the product of the base multiplied by itself "n" times.
A number that is formed by repeated multiplication by the same factor is called an exponential number or a power. It is typically represented in the form "a^n," where "a" is the base and "n" is the exponent. The exponent indicates how many times the base is multiplied by itself.
For example:
2³ is read as "2 raised to the power of 3," and it means 2 × 2 × 2 = 8.
3² is read as "3 raised to the power of 4," and it means 3 ×3 × 3 × 3 = 81.

What is the inverse function of a(b)=12•b+9/2
Answers
To find the inverse of the function a(b) = 12b + 9/2, swap 'a' and 'b', then isolate 'b' by subtracting 9/2 and dividing by 12. This gives the inverse function as a = (b - 9/2) / 12.
Explanation:To find the inverse of a function, you need to rearrange the equation so that the independent variable 'b' becomes the dependent variable. In your function, a(b) = 12b + 9/2, first you need to solve for 'b'. Here are the steps:
Swap 'a' and 'b' to get: b = 12a + 9/2 Isolate 'b' by subtracting 9/2 from both sides: b - 9/2 = 12a Divide both sides by 12 to solve for 'a': a = (b - 9/2) / 12
So the inverse function of a(b) = 12b + 9/2 is a = (b - 9/2) / 12.

A cross section of an attic is shaped like a trapezoid. It has an area of 37.4 square meters one base is 6.4 meters and the other base is 12.3 meters long. What is the height of the cross section
Answers
Final answer:
To find the height of the trapezoid, use the formula for the area of a trapezoid which is (1/2) x (sum of bases) x height. Calculate the height by substituting the given values for the area, and the lengths of the bases into the formula to find the height as 4 meters.
Explanation:
Area of a trapezoid = (1/2) x (sum of bases) x height
Given area = 37.4 m², base1 = 6.4 m, base2 = 12.3 m
37.4 = (1/2) x (6.4 + 12.3) x h
37.4 = (1/2) x 18.7 x h
h = (37.4 x 2) / 18.7 = 4 meters

Suppose that the water level of a river is 34 feet and that it is receding at a rate of 0.5 foot per day. Find the slope,including units, and write a sentence to interpret the slope in detail. Write an equation for the water level, y, after x days. In how many days will the water level be 26 feet? Graph the equation
Answers
Explanation of slope, equation, and days to reach a specific water level in a river.
Explanation:Slope: The slope represents the rate of change in water level per day. In this case, the slope is -0.5 feet/day, indicating that the water level is decreasing by 0.5 feet each day.
Equation: The equation for the water level after x days is y = 34 - 0.5x.
Days to reach 26 feet: To find when the water level will be 26 feet, you can solve the equation 26 = 34 - 0.5x to get x = 16 days. Therefore, it will take 16 days for the water level to reach 26 feet.
