The length of a rectangle is 4 times its width and the perimeter is 150

Mathematics

Stels [109]3 years ago

Answer: A. 15 feet

Step-by-step explanation:

The formula used to calculate the perimeter of a rectangle is:

P=2l+2w

Where "l" is the lenght of the rectangle and "w" is the width.

You know that the length of this rectangle is 4 times its width. This means that:

l=4w

And you know that the perimeter is 150 feet.

Then, you need to substitute  l=4w and the value of the perimeter into the formula and solve for "w":

150=2(4w)+2w\\\\150=10w\\\\w=\frac{150}{10}\\\\w=15feet

Answer:

Y = W = 15 ft.

X= L = 60 ft.

So width is 15 and the length is 60.

a round swimming pool has a circumference of 66 feet. Carlos wants to buy a rope to put across the diameter of the pool. the rop
xxMikexx [17]

Answer:

  • $11.25
  • 21 ft

Step-by-step explanation:

The formula for the circumference of a circle in terms of diameter is ...

  C = πd

Then the diameter is ...

  d = C/π

If we use π ≈ 22/7 and C = 66 ft, then we find the diameter to be ...

  d = (66 ft)/(22/7) = (66 ft)(7/22) = 21 ft

The diameter of the pool is about 21 feet.

__

Since Carlos needs 4 more feet of rope, he will want to buy 25 feet of rope for a cost of ...

  (25 ft)($0.45 /ft) = $11.25

Carlos will pay $11.25 for the rope.

A meuseum had x visitors on friday. On Saturday it had 150 more visitors than it did on friday. The total number of visitors on
ANTONII [103]

Answer:

75 people.

Step-by-step explanation:

If Friday is x, then Saturday is 150 + x. The number of people on Sunday then is (Friday + Saturday)/2, thus (x + (150 + x))/2. This then simplifies to (x + 150 + x)/2 ---> (2x + 150)/2 ---> 2x/2 + 150/2 ---> x + 75. So, Friday is x and Sunday is x + 75, to find out how many more visitors the museum have on Sunday than Friday, you subtract the two numbers. (x + 75) - x = 75.

Which expression is equivalent to StartFraction (3 m Superscript negative 2 Baseline n) Superscript negative 3 Baseline Over 6 m
Dovator [93]

Option a: \frac{m^{5} }{162n} is the equivalent expression.

Explanation:

The expression is \frac{(3m^{-2} n)^{-3}}{6mn^{-2} } where m\neq 0, n\neq 0

Let us simplify the expression, to determine which expression is equivalent from the four options.

Multiplying the powers, we get,

\frac{3^{-3}m^{6} n^{-3}}{6mn^{-2} }

Cancelling the like terms, we have,

\frac{3^{-3}m^{5} n^{-1}}{6 }

This equation can also be written as,

\frac{m^{5}}{3^{3}6 n^{1} }

Multiplying the terms in denominator, we have,

\frac{m^{5} }{162n}

Thus, the expression which is equivalent to \frac{(3m^{-2} n)^{-3}}{6mn^{-2} } is \frac{m^{5} }{162n}

Hence, Option a is the correct answer.
