The length of the diagonal of a square is 30square root 2 find the perimeter of the square

Answers

Answer 1

Answer:

120.

Step-by-step explanation:

Using the Pythagoras theorem:

(30√2)^2 = x^2 + x^2         where x =length of each side of the square

1800 = 2x^2

x^2 = 900

x = 30.

So the perimeter = 4*30 = 120.

use cross products property to solve the proportion a/6=15/2

Answers

Answer:

a = 45

Step-by-step explanation:

[tex]\frac{a}{6} = \frac{15}{2}[/tex] Original equation.

[tex]a = 6(\frac{15}{2})[/tex] To solve for a, multiply both sides by 6 to isolate a.

[tex]a = 3(15)[/tex] 6 reduces to 3 when divided by 2.

What is a Proportional Relationship?

If m is the slope or unit rate, a proportional relationship between two variables, x and y, can be represented with an equation as, y = mx.

Let's find the equation that represents the relationship represented by the graph and the table. Let's use the graph.

m = y/x

Using the point, (2, 4),

m = 4/2 = 2

Substitute m = 2 into y = mx

y = 2x

Therefore, the equation of the proportional relationship represented by the table and the graph is: y = 2x.

Answers

Answer:

Step-by-step explanation:

find 10% = 4

quadruple it = 16

half 10% = 2

half it again = 1

2.5% = 1

40% = 16

1 + 16 = 17

take 17 off of 40 = 23

100% - 42.5% = 57.5%

Answer:

See step-by-step explanation.

Step-by-step explanation:

When dividing a fraction it is not actually dividing, it is more multiplying.

Our sum looks like this:

3/5 ÷ 1/3

The method here is to flip the second fraction and change the divide sign into a multiplication sign. Here is what is looks like step-by-step.

3/5 ÷ 1/3

3/5 ÷ 3/1

3/5 × 3/1

Now we can finish the sum off by multiplying across.

3 × 3 = 9

5 × 1 = 5

9/5, this is a top-heavy fraction.

If we want it as a mixed fraction then here it is:

1. x≤5 Work: 2x+9≤19 move the constant to the right then its 2x≤19-9, then subtract the numbers and it would be 2x≤10, then divide both sides of the inequality by 2 which gives you the final answer of x≤5

2. x≥19 Work: x-7≥12 move the constant to the right then its x≥12+7, then add the numbers and get your final answer of x≥19

3. x≤4 Work: Divide both sides of the inequality by -3 and flip the inequality sign and that gives you -3÷(-3)≤-12÷(-3) and divide that which gives you x≤4

4. x<-3 Work: move the constant to the right which gives you -5x>16-1, then subtract to get -5x>15 and divide both sides of the inequality by -5 and flip the inequality sign to get x<-3

Note: This Took Forever LOL

A volleyball camp chargers $150 per camper for 10 campers. When a team brings 15 campers, the rate is reduced to $125 per camper. What is the rate of change in cost per camper ?

Answers

Answer: $6.67

Step-by-step explanation:

A volleyball camp chargers $150 per camper for 10 campers. The cost for each camper will be:

= $150/10

= $15

When a team brings 15 campers, the rate is reduced to $125 per camper. The cost for each camper will be:

= $125/15

= $8.33

The rate of change in cost per camper will be:

= $15 - $8.33

= $6.67

Yes it is true. Sum of two integers is always an integer

Step-by-step explanation:

Rule: The sum of any integer and its opposite is equal to zero. Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.
