Last year at a certain high school, there were 50 boys on the honor roll and 120 girls on the honor roll. This year, the number of boys on the honor roll increased by 22% and the number of girls on the honor roll increased by 15%. By what percentage did the total number of students on the honor roll increase? Round your answer to the nearest tenth (if necessary).
Answers
Step-by-step explanation:
50 boys increased by 22%.
that means the number 50 is multiplied by 1.22 (= 1 + 0.22), as 22% = 0.22 :
50 × 1.22 = 61
the difference is 61 - 50 = 11
120 girls increased by 15% :
120 × 1.15 = 138
the difference is 138 - 120 = 18
the total number of additional honor roll students is
11 + 18 = 29
the total number of students was originally
50 + 120 = 170 = 100%
1% = 100%/100 = 170/100 = 1.7
how many % are the 29 difference ?
as many % as times that 1% fit into 29 :
29 / 1.7 = 17.05882353... ≈ 17.1%
so, the number of honor roll students increased by about 17.1%.

Lighthouse A sounds a foghorn every 4 hours, and Lighthouse B sounds a foghorn every 10 hours.
If both lighthouses sound their foghorns at the same time, how many hours will it be until the next instance when both foghorns sound at the same time?
14 hours
20 hours
24 hours
40 hours
Answers
Answer:
The answer will be 20.
Step-by-step explanation:
If both lighthouses A and B sound their foghorns at the same time, it will be after 20 hours before both foghorns sound at the same time again.
Since lighthouse A sounds it's foghorn every 4 hours, and lighthouse B sounds it's foghorn every 10 hours.
To determine the next time when both foghorns sound at the same time;
We need then need to determine the lowest common multiple (LCM) of 4 and 10.
The lowest common multiple of 4 and 10 is going to be 20.
Therefore they will sound at the same time after 20 hours.

20 hours

Match each hypotenuse length with the leg lengths that will create a right triangle.
Answers
Answer:
see attached
Step-by-step explanation:
The Pythagorean theorem can be used to find the hypotenuse associated with each pair of legs. That tells you ...
c² = a² +b² . . . . . legs a, b; hypotenuse c
__
alternate form of Pythagorean theoremFor the purpose of this problem, it is convenient to consider a slightly different form of the equation.
For legs √a and √b, the hypotenuse √c is given by ...
(√c)² = (√a)² +(√b)²
c = a +b
That is ...
legs √a, √b ⇒ hypotenuse √(a+b)
__
application to this problemSince the legs are (mostly) given in terms of square roots, the value under the radical for the hypotenuse is simply the sum of those:
legs: √1, √2 ⇒ hypotenuse √(1+2) = √3
legs: √2, √3 ⇒ hypotenuse √(2+3) = √5
legs: √5, √3 ⇒ hypotenuse √(5+3) = √8
legs: √5, √1 ⇒ hypotenuse √(5+1) = √6
_____
Additional comment
You may not see the leg lengths given as square roots very often. This is a rather unusual set of problems for hypotenuse length.

Surface Area
Part A
What is the area of each face of cube A?
Part B
How can you calculate the surface area of cube A? What is the surface area of cube A?
Part C
What is the area of each face of cube B?
Part D
How is the area of each face of cube B related to the area of each face of cube A?
Part E
What is the surface area of cube B?
Answers
Part B: To calculate the surface area of cube A, we need to find the area of all six faces and add them together. Since all faces of a cube are identical, we can use the formula A = s^2 to find the area of one face and then multiply it by 6 to get the total surface area. Therefore, the surface area of cube A is given by the formula SA = 6s^2.
Part C: The area of each face of cube B is also equal since all faces of a cube are identical. Therefore, the area of each face of cube B is given by the formula A = s^2, where s is the length of any side of the cube.
Part D: The area of each face of cube B is related to the area of each face of cube A because both cubes have the same shape and size. Therefore, the area of each face of cube B is equal to the area of each face of cube A.
Part E: The surface area of cube B can be calculated using the same formula as cube A, which is SA = 6s^2, where s is the length of any side of the cube. Since cube B has the same shape and size as cube A, the surface area of cube B is also equal to 6 times the area of one face, which is given by the formula A = s^2. Therefore, the surface area of cube B is also equal to SA = 6s^2.
Each face of cube A has the same area since it's a cube. To find the area of each face, you can use the formula for the area of a square: side length squared.
Part B:
To calculate the surface area of cube A, you can multiply the area of one face by the number of faces. Since a cube has 6 faces, the surface area of cube A is 6 times the area of one face.
Part C:
Cube B is also a cube, so each face has the same area as the faces of cube A.
Part D:
The area of each face of cube B is equal to the area of each face of cube A since they are both cubes.
Part E:
The surface area of cube B is also 6 times the area of one face, just like cube A.

Diego correctly points out that 108 cubes with an edge length of 1/3
inch are needed to fill a rectangular prism that is 3 inches by 1 inch by 1 1/3
inch.
Answers
Answer:
Option C) 4 cubic inches is the volume of the rectangular prism.
Step-by-step explanation:
It is given that, 108 cubes with an edge length of 1/3 inch are needed to fill a rectangular prism.
Therefore, the volume of the rectangular prism is equal to the volume of the 108 cubes needed to fill that rectangular prism.
So, we need to find out the volume of those 108 cubes in order to find the volume of the rectangular prism.
The formula for finding the volume of a cube is given by,
Volume of a cube = a³
where a represents the edge length
We know that, the edge length is 1/3 inch.
⇒ a = 1/3
Volume of a cube = (1/3)³
⇒ 1/3 × 1/3 × 1/3
⇒ 1/27 cubic inches
To find the volume of 108 cubes :
⇒ 108 × volume of one cube
⇒ 108 × 1/27
⇒ 4 cubic inches.
∴ The volume of 108 cubes is the volume of rectangular prism which is 4 cubic inches (option C)

you bought a magazine for $5 and four erasers. you spent a total of $25. how much did the eraser cost?
Answers
Answer:
1 eraser = $54 erasers = $20Step-by-step explanation:
Given that,
→ Magazine = $5
→ Total cost = $25
→ 1 eraser = x
The equation will be,
→ 4x + 5 = 25
Now the value of x will be,
→ 4x + 5 = 25
→ 4x = 25 - 5
→ x = 20/4
→ [ x = $5 ]
Hence, value of x is $5.
Total= $25- $5 magazine leaves you with $20. You bought 4 erasers so you do 20/4 which is $5

Answers
PLEASE MARK BRAINLIEST!
Answer:
Use estimation
Step-by-step explanation:
A) 99 + 54
estimate that 99 is 100
estimate that 54 is 55
Add 100 and 55 together
100 + 55 = 155
Remember that you added 1 to 99 and 1 to 55
So you must subtract 2 from 155
155 - 2 = 153
Your answer is 153.
B) 244 - 99
estimate that 244 is 245
estimate that 99 is 100
Add 245 and 100 together
245 + 100 = 345
Remember that you added 1 to 245 and 1 to 99
So you must subtract 2 from 345
345 - 2 = 343
Your answer is 343.
Remember that you are doing all of this in your head!
