I need so much help with this question

Answers

Step-by-step explanation:

Looking at the graph, we can see that

A = (3, -3)

B = (10, -5)

C = (6, -8)

Reflecting over the y axis means reflecting over the big, bold vertical line in the middle. To do this for a point (x, y) simply means changing the x value to -x. For example, to reflect (6, 7) over the y axis, we would turn it into (-6, 7)

A' = (-3, -3)

B' = (-10, -5)

C' = (-6, -8)

Plot these points on the graph and connect them to get your new triangle

A concession stand vendor counts the money in the register. After 1 h, it has $42.75. After 5 h, it has $260.75. How much money will be in the register at the end of an 8-hour shift?

Answers

A concession stand vendor counts the money in the register.
 => 1 h, it has $42.75.
=> 5 h, it has $260.75.
260.75 - 42.75 = 218 are added to the money after 4 hours
=> 218 / 4 hours = 54.5 per hour
=> 54.5 * 3 additional hours = 163.5
=> 163.5+260.75=424.25

Write the perimeter of the floor plan shown as an algebraic expression in x.

Answers

Answer:

Perimeter = 2x + 64

Step-by-step explanation:

Perimeter = Sum of the lengths of the borders

From the given figure, we need to find the missing length.

Missing length = 18 - 10 = 8

Another missing length = (x + 14) - (x + 8) = x + 14 - x - 8

= 14 -8

= 6

Now let's add all the sides.

Perimeter = x + 14 + 8 + 6 + 10 + x + 8 + 18

Now add all the x terms and constants

Perimeter = 2x + 64
I believe the answer is --> p(perimeter) = 2x + 64 in the simplest algebraic expression.

During a catered lunch, an average of 4 cups of tea are poured per minute. The lunch will last 2 hours. How many gallons of tea should the caterer bring if there are 16 cups in one gallon?

Answers

Answer:

The caterer should bring 30 gallons of tea.

Step-by-step explanation:

During a catered lunch, an average of 4 cups of tea are poured per minute.

The lunch will last 2 hours.

1 hour = 60 minutes

2 hours = 60 × 2 = 120 minutes

in 120 minutes tea are poured = 4 × 120 = 480 cups

There are 16 cups = 1 gallon

480 cups = (480)/(16)

                = 30 gallons

The caterer should bring 30 gallons of tea.
There are 16 cups in a gallon. Which means that every 4 minutes, a gallon of tea is being poured. In an hour there is 60 minutes, so in an hour 15 gallons are being poured. Multiply that by 2 for the 2 hours the lunch will last and 30 gallons are going to be poured.

Answer: 30 gallons
