A car rental agency charges $33 per day to rent a car and $11.95 per day for a global positioning system (GPS). Customers are

harkovskaia [24]

(a) b = (33+11.95)d + 55.5

(b) The bill for a 5 day rental is $280.25

Step-by-step explanation:

Given,

Rent of car per day = $33

Rent of GPS per day = $11.95

Cost of gas = $3.70 per gallon

Cost of 15 gallons = 3.70*15 = $55.5 per tank

a) Write a function rule for the total bill b as a function of the days d the car is rented.

Let,

d be the number of days.

Total bill = (Rent of car per day + Rent of GPS per day )* Number of days + Cost of tank

b = (33+11.95)d + 55.5

b) What is the bill for a 5 day rental?

Putting d=5 in above function

$b = (33+11.95)*5+55.5\\b=(44.95)*5+55.5\\b=224.75+55.5\\b=280.25$

The bill for a 5 day rental is $280.25

in a given classroom the number of girls is 10 greater than number of boys if the ratio of the number of girls to the number of

Xelga [282]

Answer:

a) 35, b) 25, c) 60

Step-by-step explanation:

The number of girls is 10 more than the number of boys, so it's a good thing to choose a variable to represent the number of boys.

Number of boys: b

Number of girls: b + 10

Ratio of girls:boys is 7:5, so

$\frac{b+10}{b}=\frac{7}{5}$

"Cross multiply" to get

$7b=5(b+10)\\7b=5b+50\\2b=50\\b=25$

There are 25 boys. There are 10 more girls, so the number of girls is 35, and the total number of students is 60.

That's a packed classroom!

What conclusions can you draw from the distances that you recorded in question 7

mezya [45]

Answer:

If corresponding vertices on an image and a preimage are connected with line segments, the line segments are divided equally by the line of reflection. That is, the perpendicular distance from the line of reflection to either of the corresponding vertices is the same. Line is a perpendicular bisector of the connecting line segments.
