Answer:
the answer is B.
Step-by-step explanation:
100*20 + 1/2*(60-20)*(100 - 12)
=2000 + 1/2*40*88
=3760
Answer:
Step-by-step explanation:
8y + 11 = 4(y - 2)
8y + 11 = 4y -8
subtract 4y from both sides
4y + 11 = - 8
subtract 11 from both sides
4y = -11
divide by 4 on both sides
y = -2.75 or - y = 2.75
if you need a fraction it would be 2 3/4
Answer: D
Step-by-step explanation:
It passes through the points and is horizontal
Part 1. Imagine a clock without the hour hand, When clock strikes 3:35, the minute hand is at 7. When it strikes 3:55, the minute hand is in 11. Each gap between two adjacent digits in the clock measures 30°. This is because a revolution divided by 12 is 360/12 = 30. Then, the angle between the minute hands in the picture is equal to 4(30°) = 120°. Know that π radians is equal to 180°. Converting 120° to radians,
120°(π radians/180°) =
(2/3)π or 2.09 radians
Part 2. For this part, we determine the arc length intercepted by the angle 120° because this is the total distance travelled by the tip of the minute hand.
S = rθ, where θ is the angle in radians and r is the radius of the circle represented by the minute hand.
S = (4)(2.09)
S = 8.36 inches
Hence, the tip of the minute hand travelled a total distance of
8.36 inches.
Answer:
no because 2(6-3x)+x equals 12-5x and 2(3x)+x equals 7x
