The band club needs $1328 for decorations for this year’s concert. So far, they have $43. Find the minimum amount each of the 30 members can raise to meet their goal.
2 step Inequalities
Answer:
$42.83
Step-by-step explanation:
1: Subtract the amount they have by the amount they need.
1328-43= $1,285.
2: Divide amount they need ($1,285) by the total staff members (30). Hence the equation is 1285 ÷ 30
3: Whatever answer you get from that equation is the answer
1285 ÷ 30 = $42.83
When you divide, you are setting the amount each staff member needs to donate by seeing how much money 30 people can give (equally) that adds up to 1285.
Hope this helps :)

The farmer needs to buy fertilizer to spread on his garden. The garden is a 20 x 15 rectangle. A bag of fertilizer covers 30 ft.² of garden. How many bags of fertilizer will be needed?
Answer:
[tex]10[/tex]
Step-by-step explanation:
The area of a rectangle is given by [tex]A=lw[/tex], where [tex]l[/tex] is the length of the rectangle and [tex]w[/tex] is the width of the rectangle. Therefore, the area of a 20 x 15 rectangle is equal to [tex]20\cdot 15=300\:\mathrm{ft^2}[/tex].
Since one bag of fertilizer covers 30 square feet, the farmer needs [tex]\left \lceil \frac{300}{30}\right \rceil=\boxed{10}[/tex] bags of fertilizer.
Answer:
10 bags of fertilizer.
Step-by-step explanation:
300 area
300 / 30 = 10 bags
Solve for x in the diagram below
Answer:
x = 12
Step-by-step explanation:
The 2 angles add up to 90 degrees, so 3x + x + 42 = 90
3x + x + 42 = 90
Subtract 42 from both sides:
3x + x = 48
3x + x = 4x, so
4x = 48
Divide both sides by 4:
x = 12

Two lines, C and D, are represented by the equations given below:
Line C: y = x + 10
Line D: y = 3x + 2
Which of the following shows the solution to the system of equations and explains why?
answer choices
(5, 17), because one of the lines passes through this point
(5, 17), because the point lies between the two axes
(4, 14), because the point does not lie on any axis
(4, 14), because both lines pass through this point
Answer:
(4,14) because both lines pass through it.
Step-by-step explanation:
A "solution" to a system of equations is simply a point that both lines pass through.
First image is the solution found through graphing and the second image is the solution found through substitution.

Shanti is taking a cube-shaped gift to a friend's birthday party. She wants to wrap it but she doesn't have very much paper, so she does not overlap any of the edges.
How much paper did it take to cover the gift?
Answer:
1014 cm^2
Step-by-step explanation:
6(sides) x 13 = 1014 = surface area
Note:
I didn't really know what it meant by "so she does not overlap any of the edges." so I just calculated the surface area. Pls, notify me if my answer is correct for the other users that will see this message.

The equation below represents a story problem.
5 (-2) = -10
Which story problem could the equation represent?
A. Lana had $5 and then gave $2 to her friend. How much money does Lana have left?
B. Doug borrowed $2 from his friend every day from Monday through Friday. How much money does Doug owe in all?
C. Lana owes 5 friends a total of $2. If she owes each friend the same amount, how much money does she owe each friend?
D. Doug earns $2 for every day that he washes the dishes after dinner. Doug washed the dishes 5x this week. How much money did Doug earn?
Answer:
It can represent Story B.
Step-by-step explanation:
Story B says that a person borrowed 2 dollars, which means -2, for the days from Monday to Friday, 5 days, so he owes -2 times 5 dollars in all.
The equation represent the story of option B, Doug borrowed $2 from his friend every day from Monday through Friday. How much money does Doug owe in all?
What is mathematical operation?Other than numbers, mathematical objects can be used in operations. The coherent qualities valid and bogus can be consolidated utilizing rationale tasks, for example, and, or, and not. Vectors can be combined and divided. The function composition operation can be used to combine rotations, performing the first rotation first, and so on. the basic operation are addition, subtraction, multiplication, and division.
Given a equation 5(-2) = -10
the equation says that there is continuous reduction in any thing for 5 times
let us take an example if any person owes some amount from other, then the person owes the amount will have negative sign,
according to option A Lana had $5 and then gave $2 to her friend. How much money does Lana have left?
the equation will be 5 - 2 = 3,
according to option B . Doug borrowed $2 from his friend every day from Monday through Friday. How much money does Doug owe in all?
total amount borrowed for 5 days is 2 x5 = 10 but Doug owes 10 so the sign will be negative 5(-2) = -10,
according to option C Lana owes 5 friends a total of $2. If she owes each friend the same amount, how much money does she owe each friend?
for this equation will be total amount is 2 for 5 friends
she owes for each = 2/5 = $0.4
according to option D Doug earns $2 for every day that he washes the dishes after dinner. Doug washed the dishes 5x this week. How much money did Doug earn?
the equation is 5 x 2 = 10 and earning money is positive .
Hence the story of option B fulfill the equation correctly.

Help me please :) its very hard
Answer:
Answer B
Step-by-step explanation:
You need to first find the surface area of the triangular prism.
In order to do that, we need to first know the length of the base of the triangles on both side. So, I used the pythagorean theorem (a²+b²=c²) after making the triangle a right triangle by cutting it in HALF.
a²+b²=c²
a²+2.6²=3²
a²+6.76=9
Subtract 6.76 on both sides
a²=2.24
a=√2.24
a=1.49666295471
Now, we know that the base of HALF of the triangles on both sides of the prism is 1.496......
We need to MULTIPLY this by 2 to get the full length. So, the length of the bases of both triangles is 2.99332590942
The height of the triangles is 2.6
We are going to first find the area of one triangle and multiply it by 2, to get the area of both triangles.
Area of a triangle = base x height ÷ 2
2.6 x 2.99332590942= 7.78264736449
7.78264736449 ÷ 2 = 3.89132368224
3.89132368224 x 2 (because we have 2 triangles) =7.78264736449 cm squared
Now, we know the area of both triangles, but we now need to add the add the surface area of the rectangles in the net.
Area of a rectangle = length x width
We know that all of the three rectangles are equal in size, and that the length of each one of them is 15 cm. However, the width/height of each one is unknown. We will find out the height of each one by looking at the length of the base of the triangle attached to the first one. We know that because of the base of the triangles = 2.99332590942, the width of the attached rectangles are 2.99332590942. We found this using the Pythagorean theroem (look above).
15 x 2.99332590942= 44.8998886413
44.8998886413 x 3 (because we have 3 of the same rectangles)= 134.699665924 cm squared
Now, we must ADD the surface area of the rectangles AND the triangles.
7.78264736449 (triangles) + 134.699665924 (the three rectangles)= 142.482313288 cm squared.
The CLOSEST OPTION to the answer we got is ANSWER B because it is 142.8 cm squared, which is the closest to the answer we got which was 142.482313288 cm squared.
I really hope this helps :)
