Answer:

Length of A: 9

Width of A: 6

Length of B: 9

Width of B: 3

Step-by-step explanation:

If you look at the diagram, you can see that the length of rectangles A and B are the same, and are also the same as they were in the original square. We can find the length of each side by finding the square root of the area of the square to give us the length and width of the square which is 9. Now that we know that the length of both rectangles A and B, we can find the width of both rectangles by taking 9, and splitting it into 3 portions of 3. Since the ratio of area is 2:1, we could also do this with the area, but since we know the lengths are the same, we know the widths are proportional to the area. Using the ratio of 2:1, and the 3 portions of 3, you can combine 2 of these portions to get 6, and since the ratio 6:3 is proportional to 2:1, these measurements can be used as the width of each rectangle. Thus, the answer given above.

Answer:

Length of A: 9

Width of A: 6

Length of B: 9

Width of B: 3

Explanation:

We'll add up the values in the bottom row of the table.

A value like +150 is the same as simply saying 150

The negatives stick around.

Adding up the values in that row gets us

150 + (-50) + 400 + 300 + (-175) + (-250) = 375

This indicates that over the entire 6 month period, the overall change is +375

---------

In other words, the initial investment (call it x) has increased by 375 dollars over the 6 month period.

We can then say:

x + 375 = 1500

x = 1500-375

x = 1125

She initially invested $1125

Answer:

The mean would be 6, meaning Tara is correct.

Step-by-step explanation:

The reason to why this is the answer is that I had to add all the “number of hours in a school per day” to get 30. Then, you would have to divide 30 by 5 (because you have five different hours for a school day) to get 6. Your mean would be 6 because mean is adding up the amount of something, then dividing it of how many numbers you added.

Tara think correct mean i.e., 6 . The student spends a mean of 6 hours in school each day.

Tara is correct.

Arithmetic mean or mean or average is the number that is obtained by adding the values of all the items of a series and dividing it by the number of observations.

As per given that :

Time slots (in hours): 4, 5, 6, 7, 8

Sample A: 70 100 125 135 70

Sample B: 80 90 120 125 85

For Sample A, the mean will be

[tex]\frac{\sum fx}{\sum f}[/tex]= [tex]\frac{3035}{500}[/tex]

      =6.07

For Sample B, the mean will be

[tex]\frac{\sum fx}{\sum f}[/tex]= [tex]\frac{3045}{500}[/tex]

      =6.09

The average mean will be = [tex]\frac{6.07+6.09}{2}[/tex]

                                            =6.08

Tara assumed the correct mean.

Answer:

Not sure if this is correct but...

Perimeter=         3x+2+3x+2+2x-1+2x-1=   10x+2

Area=           (3x+2)(2x-1)           = 6x^2 +x-2

Step-by-step explanation:

Perimeter because you add up all the sides.

Area because you multiply length and width

Answer:

Perimeter=  10x+2

Area=  6x^2 +x-2

Step-by-step explanation:

The magnitude of the negative 5.8 will be 5.8 Then the correct option is D.

The absolute function is also known as the mode function. The value of the absolute function is always positive.

The absolute function is given as

f(x) = | x – h | + k

The magnitude of the number will always be positive.

For example - The value of time, length, mass, temperature etc will always positive.

The magnitude of the negative 5.8 will be

⇒ |-5.8|

When the value in the mode may be negative or may be positive, but when the mode is removed, then the value becomes positive.

⇒ |-5.8|

⇒ 5.8

The magnitude of the negative 5.8 will be 5.8

Then the correct option is D.

Step-by-step explanation:

calm down ...

don't let a strange problem description overwhelm you right away.

always try to work with the things you know first. and only when you run into something you really don't know, start thinking.

so, perimeter.

your know, what a perimeter is ? it is the circumference. all the side lengths added together. the answer to "how much distance would you have to go, to walk all the way around it one time".

so, what is the circumference of the square based on what we know ?

well, it has 4 equal sides, right ? otherwise it would not be a square.

so, the perimeter is 4×(x+2) = 4x + 8

that is perfectly fine.

now to the next part we know.

the perimeter of the triangle is the sum of its 3 sides (otherwise it would not be a triangle).

an isoceles triangle is a special triangle that has 2 equal sides.

so, we actually know all 3 sides (at least relatively) :

x+3

x+5

and ... another

x+3 (because of the isoceles property)

so, the perimeter is

x + 3 + x + 3 + x + 5 = 3x + 11

alright.

and now we also know that both perimeters are of equal length.

what did that mean ?

that both expressions deliver the same result.

therefore,

4x + 8 = 3x + 11

aha !

x = 3

bingo !

therefore, the side lengths of the triangle are

x+3 = 3+3 = 6 (both sides in the top)

x+5 = 3+5 = 8

and that's all there is to it.

it is really not necessary to panic don't you think ?

Answer:

p = -2/3a +6

a = -3/2 p +9

a = -1 1/2 p +9

a =  (-3p+18)/2

Step-by-step explanation:

2a + 3p = 18

Solve for a

2a +3p -3p = 18-3p

2a = 18 -3p

Divide by 2

a = 18/2 - 3p/2

a = 9 - 3/2 p

a = -3/2 p +9

a = -1 1/2 p +9

a =  (-3p+18)/2

Solve for p

2a +3p = 18

3p = 18 -2a

Divide by 3

p = 18/3 - 2/3 a

p = 6 -2/3a

p = -2/3a +6
