Answer:
C
Step-by-step explanation:
80 is less than 81, but more than 68.
Answer:
x = 40°
Step-by-step explanation:
using the cofunction identity
cos(90 - x) = sin x , so
90 - x = 50 , then
x = 40
that is sin40° = cos50°
Answer:
1. y = -10x + 6
2. y = -x - 6
3. y = 13x + 110
4. y = -5x + 47
5. y = 7/4 x -7
Step-by-step explanation:
2. m = - 1 and Y-intercept: -20 - (- 1)(14) = -6
3. m = 13 and Y-intercept: -7 - (13)(- 9) = 110
4. (10,-3) and (7,12)
Slope = (12 - - 3)(7- 10) = 15/-3 = -5
y- intercept = 12 - (-5)(7) = 47
5. (4,0) and (0, -7)
Slope: (-7-0)/(0-4) = -7/-4 = 7/4
y-intercept: -7 - 7/4)(0) = -7

Explanation
Answer:
A. ¹/₁₄ lb
Step-by-step explanation:
¹/₁₆ lb sand goes with ⅞ lb compost.
For 1 lb compost, the mass of sand needed is:
1 lb compost × (¹/₁₆ lb sand)/(⅞ lb compost).
We must evaluate the fraction (¹/₁₆)/(⅞).
Invert the denominator and multiply
(¹/₁₆)/(⅞) = ¹/₁₆ × ⁸/₇ Cancel the 8s
= ½ × ⅐ Multiply numerators and denominators
= ¹/₁₄
For 1 lb of compost, the mass of sand needed is ¹/₁₄ lb.
