Answer:

A) which graph represents the equation x^2 + y^2 = 2.25?

First, the general equation for a circle can be written as:

(x - a)^2 + (y - b)^2 = R^2

This is a circle of radius R centered in the point (a, b).

Then we can rewrite our equation as:

(x - 0)^2 + (y - 0)^2 = (√2.25)^2 = (1.5)^2

Then we have a circle centered at the point (0, 0) and with a radius equal to 1.5

Then we can see that the correct one is graph C.

b) Now we want to solve the system:

x^2 + y^2 = 2.25

y - x = 1

graphically.

To do it we need to graph both equations and see in which points do they intersect.

We already have the first equation graphed, so we only need to also graph the linear equation:

y - x = 1

y = 1 + x

An example of this can be seen in the graph below:

There we can estimate one of the intersections as (0.4, 1.4) and the other as (-1.4, -0.4)

Answer:$9

Step-by-step explanation:Here's what we know:

2 * 24 + 3s = 75 (the pants ($24 each) and shirts all together is $75)

What we need to do is isolate s

Simplify:

48 + 3s = 75

subtract 48 from both sides:

48 + 3s - 48 = 75 - 48

3s = 27

Divide by 3:

3s / 3 = 27 / 3

s = 9

Shirts are $9 each.

Answer:

2 x 24 = 48

48 - 75 = 27

27 ➗ 3 = 9

so the cost of 1 shirt is $9

The answer should be...

[tex]117 mm^3[/tex](if your supposed to do volume)

[tex]174mm^2[/tex](if your supposed to do surface area)

Step-by-step explanation:

volume:

3 x 3 x 3 = 27

10 x 3 x 3 = 90

27 + 90 = 117

surface area:

3 x 3 x 2 = 18

3 x 3 x 2 = 18

3 x 3 = 9

3 x 10 x 2 = 60

3 x 10 x 2 = 60

3 x 3 x 2 = 18

18 + 18 + 9 + 60 + 60 + 18 - 9 = 174

Step-by-step explanation:

Since, the data has an even amount of numbers once, you put your numbers in order you place your pointer fingers from the 1st to last number & continue to move closer. There is an even amount of numbers so you would have to add the 2 numbers up & then divide them by 2.

Answer:

A. 122cm^2

Step-by-step explanation:

We can find the area of this figure by finding the area of each rectangle, then combining the areas.

The formula for area of a rectangle is simple; the formula is length x width.

The first rectangle has side lengths of 12 and 6.      

12 x 6 = 72.

The area of the first rectangle is 72 cm.

Now, for the second rectangle.

Formula: length x width

10 x 5 = 50

The area of the rectangle is 50 cm.

Now we add both areas.

50 + 72 = 122 cm.

Therefore, the area of the figure is 122 cm^2.

Answer:

200

Step-by-step explanation:

First: work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number.

Then: divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number × 100.

Answer:

200%

Step-by-step explanation:

The change (increase) is 60.

60, divided by the original value 30, comes out to 2.

Multiplying this result by 100% yields 200%

Answer:

13.7%

Step-by-step explanation:

Nominal interest rate = [tex](\sqrt[m]{1 + effective annual interest rate} - 1 \ ) m[/tex]  

where m = number of compounding = 12

([tex]\sqrt[12]{1.146}[/tex] - 1 ) x 12 = 0.137054 = 13.7%

To round to one decimal place means that there should be only one figure after the decimal place.
