Eddie purchased 15 boxes of paper clips and 7 packages of index cards for a total of $55.40. Finn bought 12 boxes of paper clips and 10 packages of index cards for $61.70. Find the cost of one box of paper clips and one package of index cards
The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95
Step-by-step explanation:
Eldora and Finn went to an office supply store together
Eldora bought 15 boxes of paper clips and 7 packages of index cards for a total cost of $55.40
Finn bought 12 boxes of paper clips and 10 packages of index cards for a total cost of $61.70
We need to find the cost of one box of paper clips and the cost of one package of index cards
Assume that the cost of one box of paper clips is $x and the cost of one package of index cards is $y
∵ x represents the cost of one box of paper clips
∵ y represents the cost of one package of index cards
∵ Eldora bought 15 boxes of paper clips and 7 packages of
index cards for a total cost of $55.40
∴ 15x + 7y = 55.4 ⇒ (1)
∵ Finn bought 12 boxes of paper clips and 10 packages of
index cards for a total cost of $61.70
∴ 12x + 10y = 61.7 ⇒ (2)
Now we have system of equations to solve it
Multiply equation (1) by -10 and equation (2) by 7 to eliminate y
∵ -10(15x) + -10(7y) = -10(55.4)
∴ -150x - 70y = -554 ⇒ (3)
∵ 7(12x) + 7(10y) = 7(61.7)
∴ 84x + 70y = 431.9 ⇒ (4)
Add equations (3) and (4)
∵ (-150x + 84x) + (-70y + 70y) = (-554 + 431.9)
∴ -66x = -122.1
- Divide both sides by -66
∴ x = 1.85
Substitute the value of x in equation (1) or (2) to find y
∵ 12(1.85) + 10y = 61.7
∴ 22.2 + 10y = 61.7
- Subtract 22.2 from both sides
∴ 10y = 39.5
- Divide both sides by 10
∴ y = 3.95
The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95

A custodian can clean 2 classrooms in 15 minutes. At this rate, how many classrooms can a custodian clean in 76 minutes?
Answer:
10 Classroom
Step-by-step explanation:
Since,
Custodian clean 2 classrooms in 15 minutes
Then ,
Let's see how many minutes does it takes for a custodian to clean for 1 classroom
To Find that we have to divide the given minutes by the given classroom.
15/2 = 7.5
Hence, in 7.5 minutes a custodian clean 1 classroom
Therefore:
Classroom to minutes:
1 = 7.5
2 = 15
3 = 22.5
4 = 30
5 = 37.5
6 = 45
7 = 52.5
8 = 60
9 = 67.5
10 = 75
11 = 82.5
Hence, we round to the nearest number:
which is 10 classroom in 75 minutes.
For this reason, the answer is about 10 classroom

Answer:
The answer is 192.33
Step-by-step explanation:
A coaster measures 7 cm in diameter. The total area of five roller coasters must be determined.
The diameter of the coaster is d = 7 cm
The radius is:
[tex]r =[/tex] [tex]\frac{d}{2}[/tex]
[tex]=[/tex] [tex]\frac{7}{2}[/tex] [tex]cm[/tex]
[tex]= 3.5[/tex] [tex]cm[/tex]
The area of the circle is:
[tex]A =[/tex] [tex]\pi r^{2}[/tex]
= (3.14 x 3.5^2) [tex]cm^{2}[/tex]
[tex]= 38.465[/tex] [tex]cm^{2}[/tex]
We now know that the area required for five coasters is 5 x 38.465 [tex]cm^{2}[/tex]
[tex]= 192.325[/tex] [tex]cm^{2}[/tex]
Round 192.325 to the nearest hundredth and you'll get 192.33 as the correct answer.

The number of purple T shirts that the Trenton's scouting group made is 15.
What is a Pie Chart?A pie chart is a type of graph where a circle is divided into certain sectors where each sector shows a proportion of the whole.
Given is a pie chart or circle graph.
This shows the number of different colored T shirts that the Trenton's scouting group made.
Total number of T shirts = 100
Total degree of a circle = 360°
The circle is divided in to various sections with each section of different degree.
Angle measure for the purple section = 54°
Proportion of purple T shirts to the full T shirts = 54 / 360
= 0.15
Number of purple T shirts in total of 100 T shirts = 0.15 × 100
= 15
Hence the number of purple T shirts made is 15.

Answer:
Initially, as x increases, y is constant.
Afterward, the slope of the graph of the function equals 2 for all x between x = 3 and x = 5.
The slope of the graph equals -1 for x between x = 5 and x = 9.
The greatest value of y is y = 4, and it occurs when x = 5.
Step-by-step explanation:
Initially, the graph of the function is flat. The quantity y remains constant as x increases from x = 0 to x = 3. The linear equation that corresponds to the function in that region is y = 0. The slope is m = 0 because the graph is a horizontal line. The graph of the function starts to increase starting at x = 3. The slope, rise/run, once we solve it, is equal to 2 for when x is between 3 and 5. After x = 5, y starts to decrease as x increases. The slope of the graph between x = 5 and x = 9 is -1. The maximum value of y occurs at the top of the bump in the graph. The coordinates of the top of the bump are (5,4). Therefore, the maximum value is y = 4, and it occurs when x = 5.

Help with the math question please
Answer:
a) Infinite solutions = intersect at every point (2 of the same line)
m = rise/run = 3/2
b = y-intercept = (0, -3)
y = 3/2x - 3
b) No solutions = no point of intersection (parallel lines)
m = 3/2 (same slope b/c parallel)
b = (0, 2)
y = 3/2x + 2
c) One solution = one point of intersection
Solution = (4, 3)
y - y₁ = m (x - x₁)
y - 2 = m (x - 2)
m = [tex]\frac{y2-y1}{x2-x1}=\frac{3-2}{4-2} =\frac{1}{2}[/tex]
y - 2 = 1/2 (x - 2)
y = 1/2x + 1
Check to see if (4, 3) is the solution to the system:
y = 1/2x + 1
y = 3/2x - 3
1/2x + 1 = 3/2x - 3
1 = 2/2x - 3
x = 4 ✅
y = 1/2(4) + 1 = 3 ✅

Find the area of the rug. DO NOT ROUND.
Answer:
28.26 ft²
Step-by-step explanation:
Formula
Area = πr²Given :
Diameter = 6 ft⇒ Radius = 3 ft [Diameter = 2 x Radius]Solving :
Area = 3.14 x 3 x 3Area = 3.14 x 9Area = 28.26 ft²Answer:
28.26 feet²
Step-by-step explanation:
Substitute the radius in the formula:
⇒ Area of circular rug = πr²
⇒ Area of circular rug = π(6/2)² [Diameter/2 = Radius]
Simplify the R.H.S:
⇒ Area of circular rug = π(3)²
⇒ Area of circular rug = π(9) [(3)² = 3 × 3 = 9]
Take π as 3.14 and simplify:
⇒ Area of circular rug = (3.14)(9)
⇒ Area of circular rug = 28.26 feet² (Using calculator)
