the perimeter of a rectangular window is 634 inches if the length of the window is 205 inches what is the width of the window

Answers

Answer 1
Answer: So you first divide 634 by 2 to get the length of one length and one width.
634/2=317
Then you subtract 205, the length, from the length and the width(317).
317-205=112 inches. Yay!

The speed limit on highways in Florida is 70 miles per hour write and solve an inequality to find how long it will take to travel 105 miles from Orlando to St Augustine if you travel at or below the speed limit

Answers

Answer:

The time is less than or equal to 1.5 hours

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x -----> the time in hours

The inequality that represent this situation is equal to

(105)/(x)\leq 70

Solve for x

Multiply by x both sides

105 \leq 70x

Divide by 70 both sides

105/70 \leq x

Rewrite the inequality

x \geq 105/70

x \geq 1.5\ hours

therefore

The time is less than or equal to 1.5 hours

Answers

Answer:

Option D - 5

Step-by-step explanation:

Given : Table

x 1 2 3 4

y 5 10 15 20

To find : The constant of variation for the relationship shown in the following table?

Solution :

The constant of variation means the relationship between variables does not change.

The constant of variation for an equation is k=(y)/(x), where k is the constant of variation.

Now, We have given the value of x and y substitute in the formula,

x=1,y=5

k=(5)/(1)=5

x=2,y=10

k=(10)/(2)=5

x=3,y=15

k=(15)/(3)=5

x=4,y=20

k=(20)/(4)=5

Therefore, The constant of variation is 5.

So, Option D is correct.

The answer is D.

Formula: k = y/x

5/1 = 5
10/2 = 5
15/3 = 5
20/4 = 5 

If we wanted to know how high a 5th-grade student could jump, how many students would be reasonable to test? 5, 12, 30, or 200.please help

Answers

200 students would be reasonable to test because you can average the score more easily.

What is average in maths?

In plain English, an average is indeed a single number chosen to represent a group of numbers; it is often the sum of the values divided by the number of numbers in the group. The average of a integers 2, 3, 4, 7, or 9 is, for instance, 5. An average could be another statistic like the median or mode depending on the situation.

here, we have,

Because the mean would be greater if the personal incomes of a few billionaires were included, the median—the amount below which 50% of personal incomes fall and over which 50% of personal incomes rise—is sometimes used to represent the average personal income.

It is advised to avoid to use the word "average" while addressing central tendency measurements because of this.

If we wanted to know how high a 5th-grade student could jump, 200 students would be reasonable to test because you can average the score more easily.

Therefore, 200 students would be reasonable to test because you can average the score more easily.
