Answer:
D
Step-by-step explanation:
the center is (0,8)
(to solve this just flip the signs on the constants being added to x and y (there is an invisible constant of 0 being added to the x))
the radius is 7 (or √49)
Answer: 4.95 inches
Subtract: 36 - 31.05 = 4.95
Step-by-step explanation:
<em>Whoever created this question hasn't done much real electrical work! </em>
<em>An outlet (also known as a receptacle) usually requires about 4 to 6 inches of wire within the </em><u><em>junction box</em></u><em> to make the connections, depending on what else may be connected in the box. We don't have to measure to 0.05 of an inch. The insulation may have to be stripped precisely to 3/8, 1/2 or 5/8 inch for connections. </em>
The electrician used 3 feet of cable between junction boxes, and had 8 ¹/₂ inches pulled through the junction box. She needed 4 inches to connect the receptacle. How much the excess did she have to cut off?
Math questions should be realistic.
5 to be honest I just guess
First you substitute into the equation is/of=%/100. By that, I mean, 119/x=70/100. Cross multiply to get 119(100)=70x. Solve for x=170
60%
If you take the 30% and divide from the 50% you get .6 multiply that by a 100 you get 60.
30/50=.60
.60x100=60
60%
