The perimeter of a regulation singles tennis court is 210 feet and the length is 57 feet less than five times the width.
Marianna [84]

Answer:

Length = 24 and Width = 81

Step-by-step explanation:

Let Width be W

then Length = W-57

Perimeter of rectangle = 2(Length + Width)

=2 (W-57+W)= 210

4W- 114= 210

4W= 324

W= 81

Then Length = 81-57 = 24

What can you conclude from a box plot where the length of the left box and whisker is the same as the length of the right box an
Norma-Jean [14]

Answer/Step-by-step explanation:

The length of the boxes and whiskers of a box plot tells us more about the spread the data being represented is and as well as the shape of the spread.

Invariably, if the length of the left box and left whiskers is of the same length as the right box and right whiskers, this implies that the distribution of the data point is close to being symmetric, or approximately symmetrical.

Nia and Trey both had sore throats, so their mom told them to gargle with warm salt water. Nia mixed 1 teaspoon salt with 3 cups
Harrizon [31]

Answer:

Each mixture has the same amount of salt for every 1 cup of water.

Step-by-step explanation:

It is provided that:

  • Nia mixed 1 teaspoon salt with 3 cups warm water.
  • Trey mixes 1 /2 teaspoon salt with one and 1/2 cups warm water.

The ratio of the number of teaspoons of salt to the number of cups of water is 1 : 3 in Nia's solution.

On dividing the amount of salt and the amount of water by 3, the ratio will be the same.

\text{Salt}: 1\div3=\frac{1}{3}\\\\\text{Water}:3\div3=1\\

Thus 1 : 3 is equivalent to the ratio \frac{1}{3}:1, which means that Nia's solution has \frac{1}{3}teaspoon of salt for every cup of water.

The ratio of the number of teaspoons of salt to the number of cups of water is \frac{1}{2}:1\frac{1}{2} in Trey’s solution.

On dividing the amount of salt and the amount of water by 1\frac{1}{2}, the ratio will be the same.

\text{salt}:\frac{1}{2}\div 1\frac{1}{2}=\frac{1}{3}\\\\\text{Water}:1\frac{1}{2}\div1\frac{1}{2}=1

So Trey’s ratio is also equal to the ratio \frac{1}{3}:1.

Since each mixture has the same amount of salt for every 1 cup of water, they are equally salty and taste the same.
