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
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
how long will it take you to drive 135 miles at a speed of 45 miles per hour
Answer: The required time taken to drive 135 miles is 3 hours.
Step-by-step explanation: We are given to find the time taken to drive 135 miles at a speed of 45 miles per hour.
We will be using the UNITARY method to solve the problem.
We have
Time taken to drive 45 miles = 1 hour.
So, time taken to drive 1 mile will be
[tex]\dfrac{1}{45}~\textup{hour}.[/tex]
Therefore, the time taken to drive 135 miles is given by
[tex]\dfrac{1}{45}\times135=3~\textup{hours}.[/tex]
Therefore, the required time taken to drive 135 miles is 3 hours.

Create a pattern with the rule n+3
Answer:
6, 7,8,9,10
When we set n= 3
Step-by-step explanation:
Step one
The rule n+3 states that we are allowed to add 3 to any number starting from n
Step two
To practically express this rule
Say n = 3
The pattern is
= 3+3, 4+3, 5+3,6+3,+3
= 6, 7 ,8 ,9 ,10
In this exercise we have to create a pattern by placing a rule, so this pattern is:
[tex]n+3=5, 6, 8, 10...[/tex]
We know that it is not an unknown that can be any value, so the values of n will only be prime numbers and its formula can be described as:
[tex]n= prime \ numbers\\n+3= rule\\2+3=5\\3+3=6\\5+3=8\\7+3=10[/tex]

The perimeter of a rectangle is 60 meters.if the length of the rectangle is 14 meters.what is the width of the rectangle?
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?
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.
A number that is formed by repeated multiplication by the same factor is a
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.

A club raised 96% pf its goal for a charity. The club raised $1056. What was the goal?
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.
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.

A. 6
B. 9
C. 8
D. 7
12 x 3/4 = 36/4 = 9
she has walked 9 miles
Final answer:
Louise has walked 9 miles after completing 3/4 of her 12-mile fundraising walk. Thus, option b is correct.
Explanation:
The student's question asks how many miles Louise has walked if she has completed 3/4 of her 12-mile fundraising walk. To find the distance walked, multiply the total distance by the fraction completed. So, Louise has walked 3/4 of 12 miles, which is calculated as follows:
Multiply 3/4 by 12.
3/4 * 12 = 9.
Thus, Louise has walked 9 miles.

The Rational form of [tex]\sqrt[4]{5^5}[/tex] is [tex]5^{\frac{5}{4}}[/tex]
Step-by-step explanation:
Given : Radical form as [tex]\sqrt[4]{5^5}[/tex]
We have to write the given radical form in rational form.
Consider the given radical form as [tex]\sqrt[4]{5^5}[/tex]
We know the rational form of a root form is [tex]\sqrt[n]{x} =x^{\frac{1}{n}}[/tex]
