Answer:

Data: for the 10 days of practice, we have:

0.5 hours 1 time.

0.75 hours 2 times

1 hour 3 times

1.25 hours 2 times

1.5 hours 1 time

2 hours 1 time.

A) the largest amount number of times that she practiced by the same amount of time is 3 (for the 1-hour practice)

The smallest is 1 ( for the 0.5h, 1.5h, and 2h practices)

the difference is 3 - 1 = 2.

B) the time that she practiced more times is 1 hour, she practiced that amount of time in 3 different days out of the 10 days.

C) the equation can be found by multiplying the number of hours by the number of times that she practiced that amount of time, and then adding all of them:

0.5h*1 + 0.75h*2 + 1h*3 + 1.25h*2 + 1.5h*1 + 2h*1  

D) the solution for the previous equation is 11 hours. Here the correct option is A.

The diameter of a tire is 2.5 ft. Use this measurement to answer parts a and b. Show all work to receive full credit
Alla [95]

Answer:

The answer is below

Step-by-step explanation:

The diameter of a tire is 2.5 ft. a. Find the circumference of the tire. b. About how many times will the tire have to rotate to travel 1 mile?

Solution:

a) The circumference of a circle is the perimeter of the circle. The circumference of the circle is the distance around a circle, that is the arc length of the circle. The circumference of a circle is given by:

Circumference = 2π × radius; but diameter = 2 × radius. Hence:

Circumference = π * diameter.

Given that diameter of the tire = 2.5 ft:

Circumference of the tire = π * diameter = 2.5 * π = 7.85 ft

b) since the circumference of the tire is 7.85 ft, it means that 1 revolution of the tire covers a distance of 7.85 ft.

1 mile = 5280 ft

The number of rotation required to cover 1 mile (5280 ft) is:

number of rotation = \frac{5280\ ft}{7.85\ ft\ per\ rotation}=672\ rotations\\\\\\

Artyom0805 [142]

Answer: B

Step-by-step explanation:

y = azaleas

x = lilies

6y + 5x =196 total cost

y + x = 36 total number of items

y = 36 – x

6(36 -x ) +5x =196

216 – 6x + 5x = 196

-x = 196 – 216

-x = -20

Divide by -1

X = 20 lilies

Plug into y equation

Y = 36 – 20

Y= 16 azaleas

To check

6(16) + 5(20) = 196

96 + 100 = 196
