The perimeter of a rectangle is 202. The length is 26 more than 4 times the width. Find the dimensions
jek_recluse [69]

Answer:

P = 2*(26+4y) + 4y

And if we solve for y we got:

202= 52 +8y +4y

202= 52 +12 y

And replacing we got:

150 = 12y

And we got:

y = \frac{150}{12}= 12.5

And for x we got:

x = 26 +4*12.5 = 76

So then the length would be 76 and the width we got 12.5

Step-by-step explanation:

For this case we have a rectangle. The perimeter is given by:

P= 2x+2y

Where x represent the length and y the the width. We can set the following conditions:

x = 26 +4y

And if we replace the conditions we got:

P = 2*(26+4y) + 4y

And if we solve for y we got:

202= 52 +8y +4y

202= 52 +12 y

And replacing we got:

150 = 12y

And we got:

y = \frac{150}{12}= 12.5

And for x we got:

x = 26 +4*12.5 = 76

So then the length would be 76 and the width we got 12.5

The hour hand of a clock moves −30° every hour. How many degrees does it move in 2 1/5 hours? The hour hand of a clock moves ___
never [62]

The number of degrees does it move in 2 1/5 hours is -66°.

<h3>How to calculate the number of degrees?</h3>

From the information given, it was illustrated that the hour hand of a clock moves −30° every hour.

Therefore, to calculate the degree for a number of hours, we simply have to multiply.

In this case, to get the degree for 2 1/5 hours will be:

= Degree every hour × Number of hours

= -30° × 2 1/5

= -30° × 2.2

= -66°
