Answer:

Slope of line (i) = 1.5

Step-by-step explanation:

Line (i) is perpendicular to;

Line (ii) whose equation is y = $-\frac{2}{3} x + 12$

The slope of line (ii) = $-\frac{2}{3}$

* <u>Mathematics rule</u>: <em>The product of slopes of two perpendicular lines = -1</em>

∴ The slope of line (i) = -1 ÷ $-\frac{2}{3}$ = 3/2 = 1.5

Louise bought 1 1/4 pounds of roast beef at $2.00 per pound and 2 1/2 pounds of turkey at $1.50 per pound. What was her total

Travka [436]

To do this you would have to do $2.00 times 1 1/4 to get the price of roast beef and $1.50 times 2 1/2.
1)To make it easier change the fractions to decimals.
(1.25)&(2.5)
2) Then do $2.00(1.25) to get
$2.50 for roast beef
3) Then do $1.50(2.50) to get
$3.75 for turkey
4)then add them together
5)3.75+2.50=$6.25

Find the area of the following circles. a. A circle with a 8-inch radius b. A circle with a 10-kilometer radius c. A circle with

Thepotemich [5.8K]

Area of a circle is $A= \pi r^2$ . The first one, a, the radius squared is 8*8=64. So $A=64 \pi$ . If you multiply in pi as 3.14, you'll have 200.96 square inches. The second one, b, the radius squared is 10*10=100. So $A=100 \pi$ square kilometers. If you multiply in pi as 3.14 you'll have 314 square kilometers. The third one, c, the radius squared is 14*14=196. So $A=196 \pi yd^2$ . Or you could multiply in pi as 3.14 to get 615.44 yd squared. For the last one, d, the radius squared is 22*22=484 cm. Therefore, $A=484 \pi cm^2$ , or multiply in 3.14 for pi to get 1519.76 cm squared. There you go!
