A square has an area of 49 square inches. Explain how to find the perimeter of the square.

1 answer:

3 0

It is a square, so you know the sides are equal. You also know that 49 is a squared number. so you do 49 square rooted and you get 7. the perimeter is adding all the side lengths. So you take 7 and multiply it by 4 since a square has 4 sides. and u have your perimeter. 28!

If you place a 17 foot ladder against the top of a 8 foot building how many feet will be bottom of the ladder be from the bottom

Marat540 [252]

Answer:

The distance of the bottom of the ladder be from the bottom of the building is = 15 feet

Step-by-step explanation:

Given:

Length of the ladder =17 ft

Height of the building = 8 ft

To find the length between the bottom of the ladder and the bottom of the building.

Solution:

On drawing out the situation, we find out that a right triangle is formed with the ladder being the hypotenuse and the building being a leg of the right triangle.

We need to find the length of the other leg of the triangle which is the distance from the bottom of the ladder to the bottom of the building.

Applying Pythagorean theorem:

$Hypotenuse^2=Leg1^2+Leg2^2$

Plugging in values in feet from the given data.

$17^2=Leg1^2+8^2$

Simplifying.

$289=Leg1^2+64$

Subtracting both sides by 64.

$289-64=Leg1^2+64-64$

$225=Leg1^2$

Taking square root both sides.

$\sqrt{225}=\sqrt{Leg1^2}$

$15=Leg1$

∴ $Leg1=15\ ft$

Thus, distance of the bottom of the ladder be from the bottom of the building is = 15 feet

Answer:

7.04*4=x

x/3=how much the tickets cost

Step-by-step explanation:

If each of the four friends pays $7.04, the equation would be set up like this: 7.04*4=28.16. This means the total cost for tickets is 28.16. If the total cost for three tickets is 28.16, just divide the total cost by how many tickets were purchased. 28.16/3=9.39. This means one ticket cost 9.39.

If you talk of a scatter plot, regularly the x-axis is used to plot the explanatory variable, this is the possible cause; while the y-axis is used to plot the varibale that is being explained, the result, the efffect.

If you are dealing with a function or model, you the convention is to use the x-axis for the independent variable, this is the input, while the y-axis is for the output or dependent varibale (which is determined by the independent variable).

Honestly this makes no logical sense but you should take 43,118+6,549=49,667
