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
<em><u>Let us solve eqn 1 and eqn 2</u></em>
<em><u>Substitute eqn 1 in eqn 2</u></em>
Thus 84 pounds of Type B coffee is used
Answer:
the slope of gx is undefined
Step-by-step explanation:
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
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 ( 
.
Plugging the values
Arc length = 2 *3.14 * 6 ( 
.
Arc length =37.68 ( 
.
Arc length =37.68 * 0.75
Arc length XPY =28.26 m.
Therefore, Arc length XPY =28.26 m.
