JulsSmile [24]3 years ago
6 0
Given:
15 miles
10 hours

unit rate = 15 miles ÷ 10 hours = 1.5 miles per hour

This means that the distance traveled per hour is 1.5 miles. 

distance = 1.5 miles/hr * 10 hours = 15 miles
assume: 15 hours
distance = 1.5 mph * 15 hrs = 22.5 miles

Write a recursive rule for the sequence –17.-11, -5, 1, ...<br>show complete working format please ​
kogti [31]

Answer:

a_{n} = a_{n-1} + 6

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

- 11 - (- 17) = - 5 - (- 11) = 1 - (- 5) = 6

A recursive rule allows a term to be found by adding d to the previous term, thus

a_{n} = a_{n-1} + 6 with a₁ = - 17

iragen [17]

Given that,

Alonzo is $120 in debt. He makes $15 per hour. He wants to have at least $75 left over after he has paid off his debt.

To find,

The inequality and the solution.

Solution,

Let he make $x per hour. Here, $120 is fixed. $15 is added per hour.

ATQ,

120 + 15x\ge 75

For atleast, we use \ge.

Subtract 120 from both sides.

120 + 15x-120\ge 75-120\\\\15x\ge -45\\\\x\ge -3

So, the required answer is greater than -3.

A self-service car wash has 3 individual car wash stalls. Customers wait in a single line before choosing the next available sta
jeka94

Answer:

single-channel, multi -phase

Step-by-step explanation:

The concept known as '' Queuing'' is not only important in the mathematical aspect alone but it is also useful in economic matters as signifies the abundance of resources that is when we have queues it means the reason for it is that the available resources is not enough.

From the question above we have that there are 3 individual car wash stalls, it is also given that the customers wait in a single line before choosing the next available stall. This means that there is only a single-channel.

Then, we have that from the single line initially, the queues then moves to multi -phase that is to  3 individual car wash stalls.

What is the image point of (-8,9)(−8,9) after a translation right 3 units and down 1 unit?
8_murik_8 [283]

Answer:

(-5,8)

Step-by-step explanation:

The left number represents the x-axis, the right one the y-axis. A translation to the right means in the positive direction on the x-axis, which is why we add 3 to -8 which gives us -5. Down on the y-axis is in the negative direction, which means we have to subtract 1 from 9, giving us 8.
