Answer:

A. 2⅓ and D.1

Step-by-step explanation:

We are required to select the values of x that makes the inequality x>½ true.

A. 2⅓

B. 0

C.-1½

D. 1

E.-¾

Options C and E are negative numbers and are therefore less than the positive number ½.

Option B(i.e. 0) is also less than ½ or 0.5 and therefore do not satisfy the inequality given.

Options A and D are greater than ½ and therefore satisfies the inequality given.

Answer:

A) 60 Degrees

B) 550 Feet

C) 2.5 minutes

Step-by-step explanation:

a) So the wheel has completed one revolution in 10 minutes so lets first divide 100 secs with 10 minutes to calculate the the fraction of revolution

1 min = 60 secs

10 min = 600 secs

100/600 = 1/6

One complete revolution is 360 degrees and 1/6 of 360 degrees will be 60 degrees .

360/6 = 60°

b)  It takes 10 minutes to complete one revolution so if the person is on it for 7 minutes it would be 7/10 of a revolution . The ferris wheel has a diameter of 250 feet so the radius will be 125 feet because it is the half of the diameter and the circumference will be 250 π . To calculate the distance lets multiple the fraction of the revolution which is 7/10 into the circumference \frac{7}{10} * (250 pi) = 550 Feet.

C)It took 10 minutes to travel 250 π now we will use this relation to calculate 200 feet . lets suppose t is for time .

\frac{250pi}{10} =\frac{200}{t}.

After solving this equation as there is only one unknown which is "<em>t</em> "the answer will be 2.5 minutes.

A cylindrical jar's lid has a radius of 4 inches. If the volume is 351.68 in , approximately what is the height of the jar?
balu736 [363]

Answer:

7 inches

Step-by-step explanation:

The volume of a cylinder is calculated using

V = \pi {r}^{2}h

where r =4 inches is the radius and V=351.68 is the volume.

To find the height of the jar, we substitute these values and solve for h.

351.68 = 3.14 \times  {4}^{2}  \times h

351.68 = 50.24h

Divide both sides by 50.24 to get:

h =  \frac{351.68}{50.24}

h=7 inches

Therefore the height of the jar is 7 inches
