Answer:
C. 6
Step-by-step explanation:
to divide by a fraction multiply by the recirpocal of that fraction.
8/3 ÷ 9/4
reduce the numbers with GCF 4 which equals 2/3 x 9
reduce the numbers with GCF 3 which equals 2x3= 6
Answer: Length = 15 inches
Width = 12 inches
Step-by-step explanation:
The painting is rectangular.
Let L represent the length of the painting.
Let W represent the width of the painting.
Area of a rectangle = LW
Marisol is panting on a piece of canvas that has an area of 180 square inches. It means that
LW = 180- - - - - - - - - - -1
The length of the painting is 1 and 1 fourth times the width. It means that
L = 1.25W
Substituting L = 1.25W into equation 1, it becomes
W(1.25W) = 180
1.25W² = 180
W² = 180/1.25
W² = 144
W = √144
W = 12 inches
L = 1.25W = 1.25 × 12
L = 15 inches
Answer:
B) 0.0073 mm/s
Step-by-step explanation:
The rate of change of area is the product of the circumference and the rate of change of radius:
dA/dt = C·dr/dt
dr/dt = (dA/dt)/C
Of course, C = 2πr, so ...
dr/dt = (7 mm²/s)(2π·152 mm) ≈ 7/955.04 mm/s ≈ 0.0073 mm/s
