Answer:
52%
Step-by-step explanation:
62/120 * 100%
Divide by 2 on top and bottom
31/60 * 100 %
.5166666666 * 100 %
51.66666666 %
To the nearest whole number
Rounding the 1, we look at the 6 6>=5 so we round the 1 to 2
52%
Answer:
$875.39
Step-by-step explanation:
1) Divide the tax rate (6.500%) by 100 to get a decimal rate of 0.06500.
2) Multiply the purchase price ($821.95) by the 0.06500 to get a sales tax amount of $53.43.
3) Add the $53.43 sales tax to the $821.95 price to get a total of $875.38.
4) Round $875.38

<h3>
Answer: 35 (choice C)</h3>
=============================================
Explanation:
For any triangle, the three interior angles always add to 180.
D+E+F = 180
(7b+1) + (2b+1) + (b+8) = 180
(7b+2b+b) + (1+1+8) = 180
10b+10 = 180
10b = 180-10
10b = 170
b = 170/10
b = 17
Use this value of b to find the three angle measures
- D = 7b+1 = 7*17+1 = 119+1 = 120
- E = 2b+1 = 2*17+1 = 34+1 = 35 degrees
- F = b+8 = 17+8 = 25
As a check,
D+E+F = 120+35+25 = 120+60 = 180
which helps confirm the correct answers.
14+5x=3(-x+3)-11
14+5x=-3x+9-11
14+5x=-3x-2
add 2 to both sides
16+5x=-3x
subtract 5x from both sides
16=-8x
divide both sides by -8
-2=x
Hope this helps! :)
