Chau's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Chau $5.50 per pound, and type B
Anettt [7]

84 pounds of Type B coffee is used

<em><u>Solution:</u></em>

Let "x" be the pounds of type A coffee

Let "y" be the pounds of type B coffee

Cost per pound of type A = $ 5.50

Cost per pound of Type B = $ 4.20

<em><u>This month, Chau made 143 pounds of the blend</u></em>

x + y = 143

x = 143 - y -------- eqn 1

<em><u>For a total cost of $677.30. Thus we frame a equation as:</u></em>

pounds of type A coffee x Cost per pound of type A + pounds of type B coffee x Cost per pound of Type B = 677.30

x \times 5.50 + y \times 4.20 = 677.30\\\\5.5x + 4.2y = 677.30 -------- eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

<em><u>Substitute eqn 1 in eqn 2</u></em>

5.5(143-y) +4.2y = 677.30\\\\786.5 -5.5y + 4.2y = 677.30\\\\5.5y - 4.2y = 786.5 - 677.30\\\\1.3y = 109.2\\\\Divide\ both\ sides\ by\ 1.3\\\\y = 84

Thus 84 pounds of Type B coffee is used

Find the values of the ratios
OleMash [197]

Answer:

  • perimeter: 5/8
  • area: 25/64

Step-by-step explanation:

You want the ratios (red to blue), of perimeter and area, given that corresponding sides have the ratio red to blue = 5 to 8.

<h3>Perimeter ratio</h3>

The ratio of perimeters is the ratio of corresponding side lengths:

  red to blue = 5 / 8

<h3>Area ratio</h3>

The ratio of areas is the square of the ratio of corresponding side lengths:

  red to blue = (5 to 8)² = 25 / 64

__

<em>Additional comment</em>

Ratios are customarily expressed in any of three equivalent forms:

  • 5 to 8
  • 5:8
  • 5/8   "fraction" form

Find the length of arc XPY.
KiRa [710]

Answer:

Arc length XPY =28.26 m.

Step-by-step explanation:

Given : A circle with two arc XY and XPY and radius 6 m.

To find  : Arc length XPY.

Solution : We have given that arc XY and XPY .

Radius = 6 m.

Central angle formed by arc XPY = 360 - 90 = 270.

Arc length = 2 *pi* r ( \frac{central\ angle}{360}.

Plugging the values

Arc length = 2 *3.14 * 6 ( \frac{270}{360}.

Arc length =37.68 ( \frac{3}{4}.

Arc length =37.68 * 0.75

Arc length XPY =28.26 m.

Therefore, Arc length XPY =28.26 m.
