The question means that when the number is 1 more than a multiple of 4 and two more than a multiple of 5. Write out multiples of 4 with one added on to them.
5,9,13,17,21,
Then write out multiples of 5 with one added on to them
7,12,17,22,
The smallest number that both lists share is 17, so that is the answer

Need help please its my last question
Nesterboy [21]

Given:

Radius of circle = 12 units

Area of sector = 24π sq. units.

Central angle = x

To find:

The value of x.

Solution:

We have,

r=12

A=24\pi

\theta = x

We know that, area of a sector is

A=\dfrac{\theta }{360^\circ}\pi r^2

Where, \theta is central angle, r is radius.

24\pi=\dfrac{x}{360^\circ}\pi (12)^2

24\pi=\dfrac{x}{360^\circ}\pi (144)

\dfrac{24\pi}{144\pi}=\dfrac{x}{360^\circ}

\dfrac{1}{6}=\dfrac{x}{360^\circ}

Multiply both sides by 360 degrees.

\dfrac{1}{6}\times 360^\circ=x

60^\circ=x

The value of x is 60 degrees.

Therefore, the correct option is A.

Steve can jog 14 miles in 2 hours. At this rate, how many miles can he jog in 1/4 hour?
Assoli18 [71]

Answer:

1  3/4 miles in 1/4 hour.

Step-by-step explanation:

Write and solve an equation of ratios:

 x           (1/4) hr

--------- = ------------

14 mi       2 hr

Cross multiplying, we get 2x = (1/4)(14), or

                                              x = (1/4)(7), or x = 7/4

Steve can jog 7/4 miles in 1/4 hour.  That's 1  3/4 miles in 1/4 hour.
