Answer:
70%
Step-by-step explanation:
First find the ones that still need to be installed
270-81
189
Percent to be done = number to be installed / total
=189/270 =.7
Change to percent form = .7 *100% = 70%
Answer:
$54.25
Step-by-step explanation:
4/5 yards of lace = $5.60
Price per yard = 5.60 ÷ 4/5
= 5.60 × 5/4
= 28 /4
= $7 per yard
The class decided to buy another 7 3/4 yd
Cost of 7 3/4 yd = cost per yard × number of yards
= $7 × 7 3/4
= $7 × 31/4
= 217 / 4
= $54.26
Cost of 7 3/4 yd = $54.25
Answer:
y-2=2/3(x+1) OR y=2/3x+8/3
Step-by-step explanation:
y=2/3x-2 (2/3 represents your slope)
plug into this equation y-y1=m(x-x1) (m represents your slope, y1 and x1 are you points)
so y-2=2/3(x+1) OR y=2/3x+8/3 (move the -2 over, distribute the 2/3 to (x+1) and then add 2/3 to the 2 you moved over)
Step-by-step explanation:
Part A:
In math, the word "of" means "multiplied by".
So if the elevation of city D is 1/4 of the elevation of city C, then our equation is 1/4*C, or C/4
Part B:
But we already know that C = 24, so we can just plug in 24 for C in our equation:
24/4 = 6 feet
Explanation: The answer is positive because when you're dividing two positive integers, there's no possible way to get a negative number.
