Answer:

11. D

12. $7,000

Step-by-step explanation:

For the first one, $.10 is added for every mile over 50. So if someone drives 51 miles, $.10 will be added. If they drive 52 miles, $.20 will be added. In the last of the options, the initial $100 is added to the $.10 multiplied by x - 50. x represents the number of miles that he drove. x - 50 is the number of 0.10 dollars that are added to the $100.

For the second question, her sales were over $3,500, so we're looking at the second slot in the table.

The equation E = $2,500 + 0.1s + 0.2(s - 3500) tells us that her total earnings are $2,500 plus 10% of her sales plus 20% of her sales minus 20% of 3500.

To solve for s:

E = $2,500 + 0.1s + 0.2(s - 3500)

Distribute 0.2 over the terms in parentheses.

E = 2,500 + 0.1s + 0.2s - 700

Then, combine like terms.

E = 1800 + 0.3s

We know her earnings were $3,900 so we can substitute that into the equation.

3900 = 1800 + 0.3s

Subtract 1800 from both sides.

2100 = 0.3s

Divide both sides by 0.3

7000 = s

So s, the value of her total monthly sales, is $7,000

I need help I don't understand at all.

Shalnov [3]

Let's solve your equation step-by-step.

1/4x - 2 = -6 + 5/12x

Step 1: Subtract 5/12x from both sides.

So now the problem is: -1/6x - 2 = -6

Step 2: Add 2 to both sides

So now the problem is -1/6x = -4

Step 3: Multiply -6 to both sides

Now you have x alone and 24

Answer: x = 24

Estimate the perimeter of the figure to the nearest tenth.

pantera1 [17]

Answer:

The Perimeter of the Figure to the nearest tenth is 18.7 units

Step-by-step explanation:

Please note I have attached an edited version of your sketch to aid my solution. Now this question can be solved in multiple ways. Here, we shall see one of them.

Looking at the original sketch, we can see that the figure is actually a combination of a Triangle (Figure 1 in my sketch) and a rectangle (Figure 2 in my sketch). So we can simply find the sides of a Triangle and the sides of a Rectangle and add them.

Perimeter on Figure 1:

The Perimeter of a Triangle is given by the Sum of the three sides as:

$A_{T}=a+b+c$

Perimeter on Figure 2:

The Perimeter of the Rectangle is given by:

$A_{R}=2(w+l)$

where here $w$ is the width and $l$ is the length of the rectangle.

Perimeter on Sketched Figure:

The perimeter of the total figure will be two sides of the triangle and the three sides of the rectangle (as the one adjacent between Fig. 1 and 2 can not be taken into account). Thus we need to find 5 different sides and add them together.

Now since the figure is on a graph paper, we can read of the size of some sides, thus the left side of the triangle is $a=3$ units and the base of the triangle is also $b=3$ units. Now to find the last unknown side we can take Pythagorian theorem, since our triangle is a Right triangle, (i.e. one angle is 90°).

Pythagoras states that the squared of the hypotenuse of a right triangle is equal to the sum of the squares of the other two legs of the triangle (where the hypotenuse side is always across the 90° angle. So here we can say that:

$h^2=a^2+b^2\\$

where $h$ is the hypotenuse and our unknown side. So plugging in values and solving for $h$ we have:

$h=\sqrt{a^2+b^2}\\ h=\sqrt{3^2+3^2}\\\\h=\sqrt{9+9}\\ h=\sqrt{18}\\ h=3\sqrt{2}$ units.

So from figure 1 we now have two known sides:

$a=3\\h=3\sqrt{2}$

Now lets find the other three sides from Figure 2. So here similarly we can read from the graph paper that the base of the rectangle (i.e. the width $w$ ) is $w=3$ and the lengths of the rectangle, are equal and also of the same length as the hypotenuse on the triangle steps. Thus from Figure 2 we have the three remaining sides as:
