[tex] \frac{8}{ - 4} \div \frac{ - 3}{9} = 6[/tex]
Explanation:
[tex] = \frac{8}{ - 4} \div \frac{ - 3}{9} [/tex]
[tex] = \frac{2}{ - 1} \div \frac{ - 1}{3} [/tex]
[tex] = \frac{2}{ - 1} \times \frac{3}{ - 1} [/tex]
[tex] = \frac{2 \times 3}{ - 1 \times - 1} [/tex]
[tex] = \frac{6}{1} [/tex]
[tex] = 6[/tex]

Sharon buys four salmon steaks for $22.95 at her local supermarket. The weights of the steaks, in pounds, are 0.68, 0.74, 0.77, and 0.81. To the nearest cent, what is the price of salmon steak per pound?
Answer:
$7.65
Step-by-step explanation:
Given that:
Money used for buying the four salmon steaks = $22.95
Weights of steaks in pounds = 0.68, 0.74, 0.77, and 0.81
To find:
Price of salmon steak per pound, to the nearest cent = ?
Solution:
Total weight of all 4 steaks = 0.68 + 0.74 + 0.77 + 0.81 = 3
Here, to find the price of salmon steak per pound we need to divide the total money used to buy salmon steaks with the total weight of salmon steaks in pounds.
Price of salmon steak per pound = [tex]\frac{22.95}{3} = \$7.65[/tex]

A circle has a diameter with the endpoints at (–7, –7) and (–1, 1). What is the equation of the circle?
Answer:
8.4
Step-by-step explanation:
d=√(x2-x1)+(y2-y1)
d-√ (-1-(-7))^2+(-1-(-7))^2
d=√ (-1+7)^2+(-1+7)^2
d=√ (6)^2+6^2
d=√ 36+36
d=√ 72
d=6√ 2=8.4852
d=8.4
