Answer:
x = 20.4
Step-by-step explanation:
x/0.6 = 17/0.5
0.5x = 17 (0.6)
0.5x = 10.2
0.5x/0.5 = 10.2/0.5
x = 20.4
CHECKING MY WORK:
20.4/0.6 = 34
17/0.5 = 34
34 = 34
You would want to make the 6 2/3 an improper fraction, so it's 20/3
2/3 × 10 = 20/3
so 10 of (2/3) cup servings
1 1/6 hrs.....1 hr = 60 minutes......1/6 hr = 1/6(60) = 60/6 = 10 minutes....therefore, 1 1/6 hrs = 70 minutes
(7/8) / 70 = x / 1....7/8 of the wall to 70 minutes = x wall in 1 minute
cross multiply
(70)(x) = (7/8)(1)
70x = 7/8
x = (7/8) / 70
x = 7/8 * 1/70
x = 7 / 560 reduces to 1/80 <== she paints 1/80 of the wall in 1 minute
Hello! When it comes to mark up, you would add 1 to the percentage in decimal form, because the price is going up. After you do that, you multiply that number by the original price. In this case, 37.5% is 0.375 in decimal form. 1 + 0.375 is 1.375. 80 * 1.375 is 110. There. The retail price of the shoes is $110.
Answer:
C. 31.64
Step-by-step explanation:
23 = sin(36) × Hypotenuse
Hypotenuse is the baseline between the angles 36° and 54°.
Hypotenuse = 23/sin(36)
x = cos(36) × Hypotenuse
x = cos(36) × 23/sin(36) = cos(36)/sin(36) × 23 =
= 1/tan(36) × 23 = 23/tan(36) = 31.63686382... ≈
≈ 31.64
