Write the sentence as an equation. Let the variable x represent the number.

Roco draws two shapes. one of his shapes is 4 times longer and 4 times wider than the other. he found that the perimeter of the

nikklg [1K]

If two squares have different perimeters, the one with the larger perimeter will have a larger area. If two polygons have the same perimeter, then they must have the same shape. If two polygons have the same shape but are different sizes, then they must have different perimeters.

If two squares have equal areas, they will also have sides of the same length. But although "equal areas mean equal sides" is true for squares, it is not true for most geometric figures.

In order to find the perimeter or distance around the rectangle, we need to add up all four side lengths. This can be done efficiently by simply adding the length and the width, and then multiplying this sum by two since there are two of each side length.

Create2 ratios that are equivalent to the ratios below6:10 answer

Andrews [41]

Answer:

3:5, 12:20

Step-by-step explanation:

A ratio is basically just a fraction. Therefore, 6:10 is just 6/10, or 3/5, or 3:5. It's the same thing as a fraction, just with a colon.

Thus, all you need is two equivalent fractions to 6/10. Examples are 3/5, 12/20, 30/50, etc. After you find the fractions, you just need to put them back into ratio form, so 3:5, 12:20, 30:50, etc.

A family of 3 children and 2 adults visited a health club. The club charges $y an hour for each child and $x an hour for each ad

marishachu [46]

Answer: Line joining ordered pairs (0, 10) and (15, 0) and Shade the portion of the graph below this line which lies within the first quadrant.

Step-by-step explanation:

Here, The club charges $y an hour for each child and $x an hour for each adult.

And, according to the question,

In the family 3 children and 2 adults visited a health club such that the family does not want to spend more than $30 an hour at the health club.

That is, $2x + 3y\leq 30$

Which is the required inequality.

Since at origin, $2\times 0 + 3\times \leq 30$ (true)

That is, the inequality must contains the origin.

Therefore, shaded region will occur below the line.

Also, x-intercept of the given line is (15,0)

And, y-intercept of the given line is (0,10)

Thus the line will join the order pairs (15,0) and (0,10)

Also, $x\geq 0$ and $y\geq 0$ ( because charges can not be negative)

Therefore the shaded region will only contain the first quadrant.

If m^2 = 3 then what is the value of 5m^6<br><br> a. 15<br> b. 30<br> c. 45<br> d. 135

Virty [35]

Answer:

135

Step-by-step explanation:

m^2 = 3

Cube m^2

(m^2)^3 = 3^3

m^(2*3) = 27

m^6 = 27

Now multiply by 5

5 * m^6 = 5*27

5 m^6 =135

Given IQ scores are approximately normally distributed with a mean of 100 and a standard deviation of 15, the proportion of peop

weeeeeb [17]

The proportion of people with IQs above 130 is 2.3%.

<h3>How to calculate the value?</h3>

Normal distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Here the mean is 100 and a standard deviation of 15.

µ = 100, σ = 15

P(X > 130) =

= P( (X-µ)/σ > (130-100)/15)

= P(z > 2)

= 1 - P(z < 2)

Using excel function:

= 1 - NORM.S.DIST(2, 1)

= 0.023 = 2.3%

The value is 2.3%.
