Answer:

The perimeter is multiplied by 5.

Step-by-step explanation:

Perimeter of a rectangle:

The perimeter of a rectangle with sides l and w is given by:

P = 2(l + w)

The side lengths of a rectangle are all multiplied by 5.

This means that l = 5l, w = 5w. So

P_M = 2(5l + 5w) = 2*5(l+w) = 10(l + w)

What happens to its perimeter?

The rate is:

\frac{P_M}{P} = \frac{10(l+w)}{2(l+w)} = 5

The perimeter is multiplied by 5.

Thirty more than one half of the students at at canyon middle school are in band.Five less than three fifths of the students are
Fed [463]

Answer:

Students at canyon middle school = 350

Step-by-step explanation:

Students at canyon middle school = x

Band = 1/2x + 30

Athletics = 3/5x - 5

athletics.If the number of students who are in band is equal to the number of students in athletics

1/2x + 30 = 3/5x - 5

1/2x - 3/5x = -5 - 30

5x-6x/10 = -35

-x/10 = -35

= -x(1/10)= -35

x = -35 ÷ -1/10

= -35 × -10/1

= 350

x = 350

Students at canyon middle school = 350

Tanner has 200 baseball cards. Of those, 42% are in mint condition. How many of the cars are in mint condition?
Thepotemich [5.8K]

The number of cars that are in mint condition are = 84

<h3>Number of cars in mint condition</h3>

The number of baseball cards owned by Tanner = 200

The percentage of baseball cards that are in mint condition = 42%

Therefore the number of cars in mint condition

=

\frac{42}{100}  \times  \frac{200}{1}

\frac{8400}{100}

= 84

Therefore, the number of cars that are in mint condition are = 84
