Answer:

137 [tex]ft^2[/tex]

Step-by-step explanation:

1. Approach

Break up the given figure into smaller figures. One can break up this figure into a rectangle, and a triangle. After doing so, one can calculate the area of each of the smaller figures, and then add up the values.

2. Calculate the area of the triangle

If one were to cut the top figure off, one would get a triangle with a base of (3ft), and a height of (6ft). One can calculate the area of the figure using the formula;

[tex]\frac{base*height}{2}[/tex]

Substitute;

[tex]\frac{6*3}{2}\\\\= \frac{18}{2}\\\\\ 9[/tex]

3. Calculate the area of the rectangle;

Now, one is left with a rectangle with dimensions (16ft), and (8ft). To find the area of this figure, use the formula;

[tex]base * height[/tex]

Substitute;

[tex]16 * 8\\\\= 128[/tex]

4. Find the area of the whole figure

Now add the area of the triangle, and the area of the rectangle together.

(Rectangle) + (Triangle)

= 128 + 9

= 137

Answer:

10 apples

Step-by-step explanation:

We can write a ratio to solve

3 oranges     15 oranges

--------------- = -----------------

2 apples           x apples

Using cross products

3x = 2 * 15

3x = 30

Divide by 3 on each side

3x/3 = 30/3

x = 10

Answer:

He can expect to sell 10 apples

Answer:

pretty sure.

Answer:

x=125

Step-by-step explanation:

First identify what the varible means,

x = the cost of the labor per hour.

Next, write out an equation

3x + 66 = 441

Solve,

3x+66=441

Step 1: Subtract 66 from both sides.

3x+66−66=441−66

3x=375

Step 2: Divide both sides by 3.

3x/3 = 375/3

x=125

Step-by-step explanation:

Answer:

8m

Step-by-step explanation:

We can convert the trapezium into a rectangle to make finding the area easier.

Say that the top side is 9m, and that the bottom side is 12m.

12 - 9 = 3

3/2* = 1.5

*Note that we are dividing by two to get the "overhang" of the bottom side.

Now that we have our overhang, we can find the length of the "t-rect"**.

**"T-rect" refers to a rectangle that has been formed by changing a trapezium into a rectangle.

12 - 1.5 = 10.5

9 + 1.5 = 10.5

The length of the t-rect is 10.5.

84/10.5 = 8

The height of the t-rect is 8m.

Since the height of the original trapezium is equal to the height of the t-rect***,

***Since we have only adjusted the length

this also means that 8m would also be the height of the original trapezium.

Now, there is a second way of doing this.

Find the median of 12 and 9.

9, 10, 11, 12

10, 11

The median is 10.5.

84/10.5 = 8

You get the same answer. These methods could be used as a solve-then-check method to another problem like these.

Hope this helps. Have a nice day.

Answer:

slope= 1/10x and the slope represents the increase of the rental cost after x miles driven.

Step-by-step explanation:

i hope this helps :)

Answer:

so, for each of the questions you have to change the expression into slope intercept form, then use that equation to graph a line on the graph.

i'll help you out:

11. y= 3/2x+5 (0,5) (-4,2 )

12.y= -2x-5 (0,-5) (-1,-3)

13. y= -2x-3 (0,-3) (-1,-1)

14. y= x-4 (0,-4) (4,0)

Step-by-step explanation:

the first expression is the slope intercept form and the parenthesis are the points.

i hope this helps :)

Answer:

y = -2/3x + 5 1/3

Step-by-step explanation:

Find the slope:

4 - 6 / 2 - (-1) = -2/3

Put it in point-slope form:

y - 6 = -2/3(x + 1)

rearrange:

y - 6 = -2/3x - 2/3

y = -2/3x + 5 1/3

Answer:

x=12

Step-by-step explanation:

pythagreom thereom, since the figure on the left is a square all of its sides are equal so that one side that shares a side with the triangle is 9cm

9^2+b^2=15^2

b^2=144 square it

b= 12
