Andrew [12]

Answer:

A : $67.60

Step-by-step explanation:

Given:

Sales tax = 4%

She just bought a swimsuit whose full price was $80,

She presented the retailer with a coupon for $15,

Question asked:

What was the total amount that Elaine paid?

Cost price of  swimsuit = $80,

She presented the retailer with a coupon for = $15,

Remaining price = 80 - 15 = 65

Now, sale tax imposed = 4% of 65

                                      = \frac{4}{100} \times65 = \frac{ 260}{100}  = 2.6

Sale price = Remaining price after deducting coupon + sale tax

                 =  65 + 2.60 = 67.60

Thus , $67.60 Elaine paid to the retailer.

A girl scout leader rented a bus for a trip to the museum. The bus company charged $275 plus $.35 for each mile traveled over 35
slava [35]

Answer: The trip was 440 miles

Step-by-step explanation:

A girl scout leader rented a bus for a trip to the museum.

Let x represent the number of miles

traveled over 350 miles.

Let y represent the total cost of travelling x miles

The bus company charged $275 plus $.35 for each mile traveled over 350 miles. This means that for x miles, the cost will be

y = 275 + 0.35x

If the bus trip cost $429, it means that y = 429

To determine the number of miles,we will substitute y = 429 into the equation. It becomes

429 = 275 + 0.35x

0.35x = 429 - 275 = 154

x = 154/0.35 = 440

x = 440 miles

What is the value of x?<br> 52°<br> 93°<br> (x + 3)<br> 78°
gizmo_the_mogwai [7]

Answer:

Step-by-step explanation:

Step One

Find the exterior angle connected to the 93 degree angle. It is also a supplement to 93. Supplementary angles add to 180. Call the exterior angle y

93 + y = 180          Subtract 93 from both sides

y = 180 - 93

y = 87

Step two

Add all the exterior angles. They equal 360

x + 52 + 87 + x + 3 + 78 = 360    Combine the like terms

Step 3

Solve the equation

2x + 220 = 360                            Subtract 220 from both sides

2x  = 360 - 220

2x = 140                                        Divide by 2

x = 70

I don't see that anywhere, but I'm pretty sure I'm right.

What is the range of the function on the graph?all real numbersO all real numbers less than or equal to -1all real numbers less
Yuki888 [10]

The range of the function f(x) is the set of all values that function f takes.

The domain of the function f(x) is the set of all possible values for x.

From the given graph you can see that the domain is all real numbers, x\in (-\infty,\infty).

The maximal y-value that f takes is 3 at x=-1. For all another x from the domain, y is less than 3.

Thus, the range of the given function is y\in (-\infty,3].

Answer:  y\in (-\infty,3].
