If a household appliance has a wattage of 7,043 and is in use for 9 hours, how much CO2 was produced? Round to 1 decimal.

Answers

Answer: = 62.8 pounds of CO₂

Step-by-step explanation:

1 kilowatt per hour produces 0.99 pounds of C02.

The total wattage in hours used was;

= 7,043 * 9 hours

= ‭63,387‬ watts

In kilowatts;

= ‭63,387‬/1000

= 63.387 kilowatts

CO2 produced;

= 63.387 * 0.99

= ‭62.75313‬

= 62.8 pounds of CO2

Laura has 160 pounds of green beans at her vegetable stand. If she sells 10 pounds of green beans every hour, what is the percent decrease in green beans after 3 hours?

A
18.75%

B
81.25%

C
23.07%

D
16%

Answers

Given:

Laura has 160 pounds of green beans at her vegetable stand.

She sells 10 pounds of green beans every hour.

To find:

The percent decrease in green beans after 3 hours.

Solution:

We have,

Beans sold in 1 hour = 10 pounds

So, Beans sold in 3 hours = 30 pounds

Decrease in green beans after 3 hours is 30 pounds.

Now,

[tex]\%\text{Decrease}=\dfrac{\text{Decrease in green beans after 3 hours }}{\text{Initial amount of green beans}}\times 100[/tex]

[tex]\%\text{Decrease in green beans after 3 hours}=\dfrac{30}{160}\times 100[/tex]

[tex]\%\text{Decrease in green beans after 3 hours}=\dfrac{300}{16}[/tex]

[tex]\%\text{Decrease in green beans after 3 hours}=18.75\%[/tex]

Therefore, the correct option is A.

Martha read 1/6of her library books on Saturday and 5/12 of her book on Sunday, how much more does Martha have left to read

Answers

Answer: She has 5/12 left of her book to read as well

Step-by-step explanation:

Martha read 1/6 books on Saturday and 5/12 books on Sunday, then the books left to read will be 5/12.

What are arithmetic Operations?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the given information in the question,

Books read by Martha on Saturday = 1/6

Books read by Martha on Sunday = 5/12

Then, the number of books left to read is,

1 - (1/6 + 5/12)

Take LCM as 12,

[12 - (2 + 5)]/12

= (12 - 7)/12

= 5 / 12

The area of a rectangular field is 6831 m If the length of the field is 99 m, what is its width?​

Answers

Answer:

The width is 69m

Step-by-step explanation:

Set it up in a equation, W x 99 = 6831. So first thing to do is get the letter by its self. So you will do the opposite of multiplication. And what you do to one side you do to the other so you divide 6831 by 99. And you get W = 69

Answer:

Step-by-step explanation:

Area of rectangular field = length × width 99×w=6831

w = 6831/99

w=69m

Answers

Answer:

Remove the variable from the Model

Step-by-step explanation:

Normally, when considering which variable to keep and which one to drop when considering testing of the contribution of an individual regressor variable to the model, generally speaking we use one explanatory variable for between 10-15 observations.

Now, before we run our regression, we would need to run correlation analysis between all explanatory variables to detect if there's any multicollinearity, and also between the dependent variable and the regressors in order to determine the most important predictors to be included in the regression.

So after the analysis, for the null hypothesis not to be rejected, we will remove the variable from the Model.

How many solutions does the equation 3x + 6 = −1 − 3 + 4x have? (5 points)

Two
None

Infinitely many

Answers

Answer:

The equation has only one solution which is:

[tex]x = 10[/tex]

Step-by-step explanation:

Given the equation

[tex]3x\:+\:6\:=\:-1\:-\:3\:+\:4x[/tex]

Let us solve the equation to determine the type of the equation

[tex]3x\:+\:6\:=\:-1\:-\:3\:+\:4x[/tex]

subtract the number: -1 - 3 = -4

[tex]3x+6=4x-4[/tex]

subtract 6 from both sides

[tex]3x+6-6=4x-4-6[/tex]

[tex]3x=4x-10[/tex]

subtract 4x from both sides

[tex]3x-4x=4x-10-4x[/tex]

[tex]-x=-10[/tex]

Divide both sides y -1

[tex]\frac{-x}{-1}=\frac{-10}{-1}[/tex]

[tex]x=10[/tex]

Therefore, the equation has only one solution which is:

−2 1/6 divided by 1 1/4
100 points

Answers

Answer:

-1 11/15

Step-by-step explanation:

−2 1/6 divided by 1 1/4:

-2 1/6 ÷ 1 1/4 = - 13/6 ÷ 5/4 = - 13/6 × 4/5 = - 26/15 =-1 11/15

1) to divide that mixed number we'll need to turn it into an improper fraction:

[tex] - 2\frac{1}{6} = - ( \frac{6 \times 2 + 1}{6} ) = - \frac{13}{6} \\ 1 \frac{1}{4} = \frac{4 \times 1 + 1}{4} = \frac{5}{4} [/tex]

2) now let's divide it, reciprocating 1 1/4 and multiplying both fractions one by another:

[tex] - \frac{13}{6} \times \frac{4}{5} = - \frac{52}{30} = - \frac{26}{15} [/tex]

3) Hence the answer is -26/15
