A.) x = # of bottles
Fill It Up, Inc.: y = 4x
Bottles by Bob, Co.: y = 3x + 25

b.) x is the independent variable, and y is the dependent variable because it depends on the value of x. See picture below for graphs.

c.) Not sure if the class size is given, but if there are less than 25 students then Fill It Up, Inc. would be cheapest. However, if there are more than 25 students then Bottles by Bob, Co. would be cheapest. This is shown in the graph. The class size influenced the decision.

d.) The intersection in the graphs at point (25, 100) shows that for 25 bottles the price will be the same ($100).

1 hour = 3,600 seconds and 1 mile = 5,280 feet. Make a conjecture about how you could convert a speed of 15 miles per hour to fe

MrRissso [65]

Answer:

multiply by feet per mile and divide by seconds per hour

Step-by-step explanation:

To get the desired units, multiply by a factor that is equal to 1, but has the desired units in the numerator and the units you're converting from in the denominator.

For units in the denominator that you want to change, use the inverse of the above multiplier.

We have miles/hour, which has miles in the numerator. We want feet/second, which has feet in the numerator, so we need to multiply by the ratio of feet per mile: 5280 ft/mi.

We also have hours in the denominator, where we want seconds. So, we divide by the factor 3600 s/h.

$\dfrac{15\,\text{mi}}{\text{h}}\cdot\dfrac{5280\,\text{ft}}{\text{mi}}\cdot\dfrac{\text{h}}{3600\,\text{s}}=22\,\text{ft/s}$

A pair of vertical angles has measures (3x+4)° and (7x-9)°<br> What is the value of x?

Andrei [34K]

Since they are vertical they are equal to each other.

3x + 4 = 7x - 9
4 = 4x - 9
13 = 4x
3.25 = x

So the value of x is 3.25.

Hope this helps :)
