Hayden drives a taxi cab and receives $200 a day plue $0.25 for every mile he drives. He is saving up for a new laptop that costs about $1800. If Hayden drives an average of 300 miles per day, how many days will he have to drive to save enough money to buy the laptop?

Answers

Hayden will have to drive for approximately 7 days to save enough money to buy the laptop.

Given:

Daily base pay = $200

Earnings per mile driven = $0.25

Cost of the laptop = $1800

Average miles driven per day = 300

The basic arithmetic operations have been used to solve this question

1. Calculating the total earnings per day.

Total earnings per day = Daily base pay + (Earnings per mile driven × Average miles driven per day)

Total earnings per day = $200 + ($0.25 × 300)

Total earnings per day = $200 + $75

Total earnings per day = $275

2. Determining the number of days required to save enough money for the laptop.

Number of days = Cost of the laptop ÷ Total earnings per day

Number of days = $1800 ÷ $275

Number of days ≈ 6.545 (rounded to the nearest whole number)

Therefore, Hayden will have to drive for approximately 7 days to save enough money to buy the laptop.

How many cuts do you need to cut a stick into:

6 parts?
11 parts?
x parts?

Answers

Answer:

5,10,1.

Step-by-step explanation:

I'm not sure about the last one but I tried. hope this helped.

Answer:

5 cuts, 10 cuts, and for the last one it is an equation.

x parts - 1 = amount of cuts for x parts.

Step-by-step explanation:

I cannot upload an image but I can represent a half image/text to show how to find out the number of cuts.

Here is a "stick" that has been cut into 6 parts.

_ _ _ _ _ _

If you count the number of cuts in the "stick", you can tell it is 5 cuts, which is one less than 6. Let's try cutting a stick into 11 parts now.

_ _ _ _ _ _ _ _ _ _ _

As you can see, there are 10 cuts in the "stick". Therefore, you can use the equation, x-1 = amount of cuts, where x represents the number of parts the stick has been cut into.

The final answer:

5 cuts

10 cuts

x-1

Which expression represents the area of triangle ABC in square meters?
A. 1/2 x 14 x 57
B. 1/2 x 14 x 64
C. 1/2 x 24 x 40
D. 1/2 x 24 x 57

Answers

Answer:

A. 1/2 x 14 x 57

Step-by-step explanation:

The formula for the area of a triangle is base x height x 1/2

To calculate the base you would need to add the two numbers on the bottom of the triangle: 20 + 37 = 57

The photo shows that the height is 14 so it would be

1/2 x 14 x 57

Formula of area of triangle-1/2

The base is 20+37 =57

so the answer is 1/2*57*14
