7/8+3/8=10/8
10/8=5/4
The answer as an improper fraction is 5/4 and 1 and 1/4 as a mixed fraction.
Hope I didn't mess up for your sake.
Answer:
it is the 3rd one
Step-by-step explanation:
Answer: x = 480
Steps: x/2.4 + 39 = 239
Subtract 39 from both sides: x/2.4 + 39 - 39 = 239 - 39
Simplify: x/2.4 = 200
Multiply both sides by 2.4: x/2.4 × 2.4 = 200 × 2.4
Simplify: x = 480

Answer:
86.634
Step-by-step explanation:
The distance from the bottom of the wheel to a point on the ground can be modeled by a sine function. h(t)=a*sin(kt)+b. b is the height of the wheel, or 4m. a is the radius of the wheel, 50/2=25m. 2pi/k is the 5sinof thw revolution, so 2pi/k=6/3=2, k=pi. h(t)=25sin(pi*t)+4.
