New Orleans averages 77% humidity in the mornings, but it decreases by 20% in the afternoon. What is the average relative humidity in the afternoon in New Orleans? (enter a percent rounded to the tenths place)

Answers

Answer 1

Answer: 61.6%

Step-by-step explanation:

The afternoon humidity average is 20% of the morning average.

The morning average is 77% so the afternoon average must be:

= Morning average * ( 1 - percentage decrease)

= 77% * (1 - 20%)

= 77% * 80%

= 61.6%

Jason goes to the movies and purchases candy for $4.55. If he buys a total of 5 movie tickets and spends a total of $20.35, how much was each ticket?

Answers

3.16 per movie ticket

First you want to subtract the candy amount 4.55 from the total 20.35 that way we can get the total for the 5 tickets by themselves

20.35-4.55= 15.80

Then you want to divide the total for all five tickets by 5 which will get us the total for one ticket

15.80/5=3.16

Answers

Answer:

200 duckings (350:200)

Step-by-step explanation:

7:4 and 350:x

350/7 = 50

40 times 50 = 200

350:200

        200/50 = 7

The solution is, 200 ducklings (350:200) ducklings are there​.

What is ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

here, we have,

given that,

The ratio of ducks to ducklings at a park is 7:4.

If there are 350 ducks,

let , x ducklings are there​

so, we get,

7:4 and 350:x

now,

350/7 = 50

A graph titled Monthly Sales and Advertising Costs has Advertising Costs (1,000 dollars) on the x-axis and sales (1,000 dollars) on the y-axis. A line goes through points (6.4, 117) and (6.6, 120). The slope of the trend line is 15. What does that mean in regard to the data of the scatterplot? Check all that apply. The slope represents the rate of change of the data. Advertising costs increase $15,000 as sales increase by $1,000. Sales increase $15,000 as ads increase by $1,000. A positive slope infers a negative correlation. A positive slope infers a positive correlation.

Answers

The data in the scatterplot on monthly sales and advertising costs, show that:

The slope represents the rate of change of the data. Sales increase $15,000 as ads increase by $1,000.A positive slope infers a positive correlation.

What can be inferred from the graph on Monthly sales?

In a linear model, the slope is used to depict the change in the value of y as a result of a change in x. If this slope is positive, then there is a positive relationship between the y and x values.

In this scenario, the slope is positive which shows that there is a positive relationship between sales and advertisements such that they both increase together.

Solve this system of equations:
2x + 10y= 24
X = y-6

Answers

Answer:

(-3,3)

Step-by-step explanation:

Substitute x for the first equation

2(y-6) + 10y= 24

2y-12+10y=24

12y=36

y=3

Now solve for x by plugging in 3

x = 3-6

x=-3

Answer:

x = -3

y = 3

Step-by-step explanation:

2x + 10y = 24

x = y - 6

plugin x = y - 6 into the first equation

2(y - 6) + 10y = 24

solve for y

2y - 12 + 10y = 24

12y = 36

y = 3

plug y back into x = y - 6

x = 3 - 6

x = -3
