Anne has a 10 3/4 pounds bag of flour.each time she bakes a batch of rolls she uses 2 1/6 pounds of flour.how many pounds of flo

BaLLatris [955]

If you would like to know how many pounds of flour remain after Anne bakes 3 batches of rolls and Anne has a 10 3/4 pounds bag of flour and each time she bakes one batch of rolls, she uses 2 1/6 pounds of flour, you can calculate this using the following steps:

for 3 batches of rolls, she needs:
3 * 2 1/6 = 3 * 13/6 = 13/2 = 6 1/2 pounds of flour

now, you have to subtract 10 3/4 and 6 1/2:
10 3/4 - 6 1/2 = 43/4 - 13/2 = 43/4 - 26/4 = 17/4 = 4 1/4 pounds of flour

Result: 4 1/4 pounds of flour remain after Anne bakes 3 batches of rolls.

The perimeter of a quadrant of a circle is 71.4cm. Find its area

Karolina [17]

Answer:

circle: 6490.9 cm², quadrant: 1622.7 cm²

Step-by-step explanation:

The circumference of the entire circle is known as 2πr and it is 4 times the given value, since a circle has 4 quadrants:

2πr = 4·71.4 = 285.6, so r = 285.6 / 2π ≈ 45.45

The area of a circle is πr², filling in the value for r we just found:

πr² = π 45.45² ≈ 6490.9 cm²

So the area of a quadrant is one fourth of that:

6490.9/4 = 1622.7 cm²

The question about "its area" can denote the entire circle, or just the quadrant, so two answers are provided.

Oduvanchick [21]

Answer:

1. cost per chair: $86.40

2. selling price per chair: $146.88

Step-by-step explanation:

1. The total cost per chair will be the sum of the cost of materials and the overhead cost (equipment, energy, labor, marketing). The cost of materials is ...

$500/(16 chairs) = $31.25/chair

So, the total cost is ...

cost of each chair = material cost + overhead cost

= $31.25 +55.15

cost of each chair = $86.40

2. We assume the markup is 70% of the cost, so will be ...

0.70 · $86.40 = $60.48

Then the selling price of the chair will be ...

selling price = cost + markup

selling price = $86.40 +60.48

selling price = $146.88
