Four identical rectangles form the square. What is the perimeter of the square, if the perimeter of each rectangle is 40 inches?

Answers

Answer 1

Answer:

64

Step-by-step explanation:

so basically first I wanted to find the width, if you draw a model, it would be easy, so

I make 4 rectangles, one on top of the other for all of them.

so if you turn it clockwise 90 degrees, the rectangles are the same so if you draw them together then they over lap you can see that you can make a x:y for the lengths. If the width of the rectangle is 1 then the length of the rectangle is 4, 1:4 ,  so now we use the perimeter of 40 so now if the width is w and the length is l then wl is 20 (40/2) si niw 20/(1+4) which is 20/5 which is 4, so now we know that the width of the rectangle is 4 and the length is 4x4 which is 16 so now we can calculate the perimeter of the square, we know that the side length of the square is 16, so all we have to do is 16x4 which is 64.

Me up rich goes to the skate park and tents a skateboard for 4.00 per hour they make him rent a helmet for one time 6.00 fee if he only has $30 to spend at the park then select the equation that can be used to calculate h the number of hours he can rent the skateboard

Answers

Let, x be the maximum hours he can rent skate board and helmet.

So, total price :

T = 4x + 6x

Now, it is given that he has only $30.

Therefore,

Total price should be less than or equal to $30.

4x + 6x ≤ 30

10x ≤ 30

x ≤ 3

Therefore, the maximum number of hours he can rent the skateboard is 3 hours.

Hence, this is the required solution.

Hello.

The answer is choice A. angle 1 = 118, angle 2 = 118

Explanation:

The four angles above are congruent (meaning the same) to the ones beneath.

Angles 1 and 2 are also congruent, so they will measure the same.

Lets label the angles above A, B, C, D.    B being the known angle, which is 118°. The angles beneath can be labelled E, F, G, H.

∠B ≅ ∠D

∠ABCD ≅ ∠EFGH

∠BD ≅ ∠FH

FH (or 1 and 2) equal 118.

Step-by-step explanation:

In a function the x values cannot repeat. Look at each answer choice and see if an x repeats:

The first choice (top left) has the x value, -6, repeating. It cannot be a function.

The second choice (top right) does not have an x value repeat. This makes it a function!

The third choice, (bottom left) does not have an x value repeat. This makes it a function!

The fourth choice, (bottom right) does not have an x value repeat. This makes it a function!

How much is it | -7.9|?
Plllzzzzzz help mark you brainliest

Answers

Answer:

7.9

Step-by-step explanation:

When a number (or multiple numbers) is placed between two lines like this | |, that is the absolute value grouping symbol. Absolute value is the distance between the grouped number(s) and another defined number. In this case there are no other given numbers so 0 is assumed.

Now, say a friend is driving to your house and you call them to ask how far away they are from arriving (in distance), and they say "Around negative 5 miles away." That doesn't make sense! Distance can never be negative, and because absolute value is the distance between a number and another, a number within that grouping symbol can never be negative if there is a solution. Therefore, |-7.9| would be 7.9, because -7.9 is that exact amount away from 0.

Answers

Answer:

0.0390cm/min

Step-by-step explanation:

We are expected to do a unit conversion here.

let us convert days to minutes first

6.5days to minutes

1 day has 1440miuntes

6.5 days has x minute

cross multiply we have

x=6.5x1440

x=9360minute

let us convert yards to cm

1 yard to 91.44 cm

4 yards has xcm

cross multiply we have

x=4x91.44

x=365.76cm

the speed in cm per mins is

speed=365.76/9360m

speed=0.0390cm/min

In △FGH, FH ≅ FG. Which angles are congruent? Select both angles that are congruent

Answers

angles FGH and FHG

Step-by-step explanation:

Since this is a triangle, and the question states that FH=FG, you know that the triangle is an isosceles triangle. If you use an isosceles triangle, you know that the bottom two angles are the same degrees. Since the F is the same for both lines, you can determine that F is the top point of the triangle. As such, is you draw the triangle out, you will find the answer is  angles FGH and FHG

Let's see what to do buddy...

_________________________________

Step (1)

We know that the sum of the interior angles of any n-sided figure is obtained from the following equation :

[tex](n - 2) \times 180[/tex]

Our figure has 5 sides ;

So , sume the interior angles of it equals :

[tex](5 - 2) \times 180 = 3 \times 180 = 540 \\ [/tex]

_________________________________

Step (2)

First look at the photo which I post.

According it we have :

[tex](180 - x) + 120 + 85 + (2x - 10) + 90 = 540 \\ [/tex]

[tex]2x - x + 475 - 10 = 540[/tex]

[tex]x + 465 = 540[/tex]

Subtract the sides of the equation minus 465 :

[tex]x = 540 - 465[/tex]

[tex]x = 75[/tex]

why is math hard and important​

Answers

Answer: Math seems difficult because it takes time and energy. Many people don't experience sufficient time to "get" math lessons, and they fall behind as the teacher moves on. Many move on to study more complex concepts with a shaky foundation. And then often end up with a weak structure that is doomed to collapse at some point.

Step-by-step explanation: math is important because some things in math are gonna be used in your daily life for example adding, subtracting, division Etc and also because Math helps us think analytically and have better reasoning abilities. Analytical thinking refers to the ability to think critically about the world around us. Analytical and reasoning skills are essential because they help us solve problems and look for solutions.

List the following in order from least steep to most steep.
f(x)= -3/4x
g(x)= -5x
h(x)= 5/7x
j(x)= 11/3x

Answers

Answer:

h(x), f(x), j(x), g(x)

Step-by-step explanation:

Given functions

f(x)= -3/4x g(x)= -5x h(x)= 5/7x j(x)= 11/3x

To compare steepness we'll compare absolute values of slopes

The steepness increases as the slope increases

The slopes are

3/4, 5, 5/7, 11/3

Comparing the fractions

3/4 = 21/28, 5/7 = 20/28, so 3/4 > 5/7

And

11/3 < 4  

So the order is

5/7 < 3/4 < 11/3 < 5

As functions, the order is

h(x), f(x), j(x), g(x)
