The number of people living on a remote island decreases by 9% every 10 years. In 1950 there were 18000 living on the island. Calculate how many less people will be living on the island in 2020.

Answers

Answer 1

Answer: 9,301 people

Step-by-step explanation:

First find the number of years that have passed:

= 2020 - 1950

= 70 years

Population decreases every 10 years so in 7 years it would have increased:

= 70/10

= 7 times

In 2020 therefore:

= 18,000 * (1 - 9%)⁷

= 9,301 people

A recipe for sparkling water calls for 1 1/2 quarts of sparkling water and 3/4 quarts of grape juice how much sparkling water will you need to mix 9 quarts of grape juice

Answers

Answer: 18 quarts

Step-by-step explanation:

Quantity of sparkling water and gape juice are used in proportion in  the recipe.

Let x=  quantity of sparkling water when 9 quarts of grape juice is used.

Then,

[tex]\dfrac{x}{9}=\dfrac{1\dfrac12}{\dfrac34}\\\\\Rightarrow\ =\dfrac{x}{9}=\dfrac{\dfrac32}{\dfrac34}\\\\\Rightarrow\ \dfrac{x}{9}=\dfrac{4}{2}\\\\\Rightarrow\ x= 2\times9\\\\\Rightarrow\ x=18[/tex]

Hence, 18 quarts of sparkling water is required to mix with 9 quarts of grape juice.

You estimate that a puppy weighs 12 pounds. The actual weight of the puppy is 14 pounds. Find the percent error. Round your answer to the nearest hundredth of a percent.

Answers

Answer:

The Estimated weight of the puppy = 12 pounds

Actual weight of the puppy = 14 pounds

Difference in estimated weight and actual weight = 14 - 12

= 2 pounds  

⇒ [(14 - 12)*100]/14

⇒ (2*100)/14

Answers

Answer:

B

Step-by-step explanation:

Which of the following can be done by using conditional formatting?

Calculate quarterly sales.

Highlight all “no” responses.

Count the number of students in high school.

Calculate average scores on a math test.

Conditional formatting applies formatting to cells if specific conditions are met. For example, conditional formatting can be used to apply background color to “no” responses in a customer satisfaction survey. This will allow the business owner to quickly locate and read customer complaints and identify areas for improvement.

Conditional formatting involves applying cell formats to certain cells, if and only if they meet certain criteria.

Highlighting all "no" responses can be done using conditional formatting.

Options (a), (c) and (d) are all direct calculations that can be executed using Microsoft Excel functions and formulas such as:

SUM; to calculate quarterly sales (a)COUNT, to count number of students (c)AVERAGE, to calculate the average score (d)

However, option (b) indicates that;

The cell is to be highlighted

And the condition for highlighting the cell is that:

The content of the cell is "no"

By comparing the above analysis to the meaning of conditional formatting, we can conclude that, conditional formatting can only be applies to option (b).

Write an equation of the line that passes through (-3,3) and is perpendicular to the line 2y = 8x - 6.

Answers

Answer:

y = -0.25x + 2.25

Step-by-step explanation:

First, you can simplify the equation of the line it's perpendicular to (2y = 8x - 6) by dividing both sides by 2. This means you would get y = 4x - 3. From that you can conclude that the slope of that line is 4.

Lines always have a slope that is the negative reciprocal of the slope of the line they are perpendicular to, so you know the slope of the line is going to be -1/4.

So far, you have the equation y = -1/4x + b and you have to find b.

You can substitute in the point (-3, 3) so you would have 3= -1/4 * -3 + b

Solving,

3 = 3/4 + b

b = 2 and 1/4

Therefore the equation is y = -1/4x + 2 1/4 or y = -0.25x + 2.25

Answer:

Piece A: 42 inches

Step-by-step explanation:

If the pipe is 56 inches long and divided into 2 parts with a 3;1 ratio, then you would divide 56 by 4 (3;1->3+1) to get 14. 14 would be the smaller piece, then you'd multiply 14 by 3 to get 42 inches because theres 3 parts for the larger piece in the ratio of 3;1. :) the explanation is probably really weird but the answer should be correct anyways

EQUATIONS

We'll solve this equation:

5x + 17 = 4(3x - 1)

First, let's apply the distributive property:

‎      ‏‏‎5x + 17 = 4(3x - 1)

‎      ‏‏‎5x + 17 = 12x - 4

Now, add 4 to both sides of the equation:

‎      ‏‏‎5x + 17 = 12x - 4

5x + 17 + 4 = 12x - 4 + 4

‎      ‏‏‎5x + 21 = 12x

Substract 5x from both sides:

‎  ‎     ‏‏‎5x + 21 = 12x

5x - 5x + 21 = 12x - 5x

‎      ‏‏‎‎      ‏‏‎‎   21 = 12x - 5x

‎      ‏‏‎‎      ‏‏‎‎   21 = 7x

Now, divide both sides by 7

‎      ‏‏‎‎   21 ÷ 7 = 7x ÷ 7

‎      ‏‏‎‎   ‎    ‏‏‎‎ 3 = x

Therefore, x = 3.

‎      ‏‏‎‎    

B. The equation has one solution.

Answer:

Option B. One Solution

Step-by-step explanation:

5x+17= 4(3x-1)

5x+17 = 12x-4

17+4 = 12x-5x

21. = 7x

thus, x=3 (one solution)
