c. Bradley's dad used a light bulb that consumed 5000 joules in 50 seconds. What is the
unit rate at which this light bulb used energy?

Answers

Answer:

100 joules/ second

Step-by-step explanation:

5,000/50 seconds = 100 joules/ second

If a light bulb that consumed 5000 joules in 50 seconds, then the unit rate at which this light bulb used energy is, 100 joules/seconds or 100 watts.

What is the rate?

Rate is a ratio of change in one quantity w.r.t. change in another quantity. The net change in one quantity is written as, Δy and the net change in another quantity is written as, Δx.

So formula for the rate is,

m = change in one quantity/change in another quantity = Δy/Δx

Given that,

A light bulb that consumed 5000 joules in 50 seconds,

The unit rate at which this light bulb used energy = ?

To find the unit rate,

we can divide the energy consumed (in joules) by the time it took to consume that energy (in seconds):

Unit rate = 5000/50 joules/seconds

              = 100 Watts

Note: 1 Watt = 1 Joule/second,

so the unit rate can also be expressed as joules per second.

Hence, the unit rate at which the light bulb used energy is 100 Watts.

Meghan has her own business. When she makes money, it is called income. When she spends money, it is called expenses. Choose the phrases below to explain how to use positive or negative integers to represent income and expenses. You would use positive integers to represent income because it is a Choose... amount. You would use negative integers to represent expenses because they are opposites of income.

Answers

Answer and explanation:

When you use positive interger to represent income, it shows that there has been an addition instead of a subtraction in money value to the business. In other words money is coming in instead of going out. Example when there is profit on goods sold say $10, it is indicated with a positive integer 10 to indicate addition in terms of operating income

When you use a negative value to represent expense, it indicates there has been a subtraction instead of an addition in money value. In other words money is going out of the business and not coming in. Example when there is a transportation expense to convey goods to the buyer, it is recorded as expenses subtracted from say revenue sales of the business. expenses are usually indicated in brackets in accounting to show negative value, although not a requirement since they are already named and recognized as expenses and subtracted regardless

Answer:

1. C. The managers used a cluster sample

2.  B)The managers used a systematic sample.

3. The managers used a stratified sample.

Step-by-step explanation:

1. In a cluster sampling method, the population would be divided into several small units called cluster by the researcher. Within these clusters we randomly pick one or more to observe.

2. In systematic sampling we select elements from an ordered sampling frame.

3. In stratified sampling, the population is divided into several stratas and the researcher then selects randomly to complete the sampling process

x = -9

A. addition property of equality
B. subtraction property of equality
C. multiplication property of equality
D. division property of equality

Answers

The answer would be B

The addition property of equality was used to solve this equation. option A is correct.

A solution is given we have to determine the solution contains which property of equality.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
x − 5 = -14

x − 5 + 5 = -14 + 5

x = -9

We can see, in step 2 5 is added to both sides of an equality, which implies the property of additions.

Thus, the addition property of equality was used to solve this equation. option A is correct.
