Answer 1

Answer:

140.4ft^2

Step-by-step explanation:

since all four sides are equilateral triangles, you only need to find one triangle and multiply by 4.

area of triangle = 0.5×base×height = 0.5×7.8ft×9ft =35.1ft^2

surface area of pyramid= 35.2ft^2 × 4 = 140.4ft^2

A custodian can clean 2 classrooms in 15 minutes. At this rate, how many classrooms can a custodian clean in 76 minutes?

Answers

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

What happens to a 44-degree angle if you rotate it 90 degrees counterclockwise?

Answers

Answer:

We will have a new angle \theta_{new}=143^{\circ}θ

new

=143

Step-by-step explanation:

If we rotate this angle 90 degrees counterclockwise we just need to add both angles, which means:

\theta_{new}=44^{\circ} + 99^{\circ}=143^{\circ}θ

new

=44

+99

=143

Therefore, we will have a new angle \theta_{new}=143^{\circ}θ

new

=143

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.

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

Answers

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

Help with the math question please

Answers

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 ✅

Diameter = 6 ft⇒ Radius = 3 ft [Diameter = 2 x Radius]

Solving :

Area = 3.14 x 3 x 3Area = 3.14 x 9Area = 28.26 ft²

Answer:

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)
