last year austin texas received 23.5 inches of rainfall. this year , austin recieved 21.2 inches of rainfall find the percent of decrease in the number of inches of rainfall. round your answer to the nearest tenth of a percent, if necessary

Answers

Answer 1

Answer:

9.8 percent decrease

Step-by-step explanation:

To find the percent decrease, we take the original value and subtract the new value and divide by the original value.

percent decrease = (original - new)/ original

                                = (23.5 - 21.2)/ 23.5

                                =2.3/23.5

                                =.09787234


This is in decimal form.  Multiply by 100 to put it in percent form

9.787234 percent

Round to the nearest tenth so we look at the 8 and round up.

9.8 percent decrease

What is the eighth term in the arithmetic sequence defined by the explicit formula an=2n+7? Enter your answer in the box.

Answers

Answer:

The 8th term is 23

Step-by-step explanation:

If we are given the formula for the sequence

an=2n+7,

then to find the 8th term we substitute n=8 into the formula.

a8 = 2(8) +7

a8 = 16+7

a8 = 23

The 8th term is 23

five more then -8 times a number is 29. What is the number? Let the mystery number be represented by n.

Answers

Answer:

The mystery number is -3

Step-by-step explanation:

five more then -8 times a number is 29.

-8n +5 = 29

Subtract 5 from both sides

-8n +5-5 = 29-5

-8n = 24

Divide by -8 on each side

-8n/-8 = 24/-8

n= -3

The mystery number is -3

The mystery number in the equation is -3, determined by solving the algebraic equation 5 + (-8 × n) = 29.

The equation given in the problem statement translates to the mathematical expression 5 + (-8 × n) = 29, where n is the mystery number. To find the value of n, we can perform the following steps:

Subtract 5 from both sides to get -8n = 24.

Divide both sides by -8 to isolate n, giving us n = 24 / -8.

Calculate the result to find that n = -3.

Therefore, the mystery number is -3.

Find the x-intercepts (solve for x) for the following AND PLEASE SHOW YOUR WORK! y=−2x^2−9x+5

Answers

Answer:

see explanation

Step-by-step explanation:

To find the x- intercepts set y = 0, that is

- 2x² - 9x + 5 = 0

To factorise the quadratic consider the factors of the product of the coefficient of the x² term and the constant term that sum to give the coefficient of the x- term.

product = - 2 × 5 = - 10 and sum = - 9

The factors are - 10 and + 1

Use these factors to split the middle term

- 2x² - 10x + x + 5 = 0 ( factor the first/second and third/fourth terms )

- 2x(x + 5) + 1(x + 5) ( factor out (x + 5) )

(x + 5)(- 2x + 1) = 0

equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

- 2x + 1 = 0 ⇒ x = [tex]\frac{1}{2}[/tex]

x-intercepts are x = - 5 and x = [tex]\frac{1}{2}[/tex]

Find the area of this trapezoid. Be sure to include the correct unit in your answer.

Answers

Answer:

the area of this trapezoid= 81 square inches

Step-by-step explanation:

To find area of trapezoid , we use formula

[tex]Area = \frac{a+b}{2} * h[/tex]

Where a,b are the base of the trapezoid

h is the height of the trapezoid

Here a= 3 in

b = 15 in

h = 9 in

Plug in all the values in the formula

[tex]Area = \frac{a+b}{2} * h[/tex]

[tex]Area = \frac{3+15}{2} * 9[/tex]

[tex]Area = \frac{18}{2} * 9[/tex]

Area = 9 * 9 = 81

the area of this trapezoid= 81 square inches

If the points P (7, 12), Q (-3, -12) and R (14, 5) lie on a circle with the center C (0, 2), then the distance OP, OQ and OR are the same.

The formula of a distance between two points:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute:

[tex]OP=\sqrt{(2-7)^2+(0-12)^2}=\sqrt{(-5)^2+(-12)^2}=\sqrt{25+144}=\sqrt{169}\\\\\boxed{OP=13}\\\\OQ=\sqrt{(2-(-3))^2+(0-(-12))^2}=\sqrt{5^2+12^2}=\sqrt{25+144}=\sqrt{169}\\\\\boxed{OQ=13}\\\\OR=\sqrt{(2-14)^2+(0-5)^2}=\sqrt{(-12)^2+(-5)^2}=\sqrt{144+25}=\sqrt{169}\\\\\boxed{OR=13}[/tex]

OP = OQ = OR, therefore the points P, Q and R lie on one circle.

Step-by-step explanation:

4 x 4 x 4 = 64

100/5 = 20

20 x 4= 80

80 + 64 =144

Answer:

100 /( 5 x 4 + 4³) = 1 4/21  

100 / 5 x 4 + 4³ = 144

Step-by-step explanation:

100 /( 5 x 4 + 4³)

PEMDAS tells us to do what is inside the parenthses

We will do the power in side the parentheses first  4^3 = 64

100 /( 5 x 4 + 64)

Now we will multiply

100/(20+64)

Now we add inside the parentheses

100/84

Divide the top and bottom by 4

25/21

Changing from an improper fraction to a mixed number

1 4/21

OR  

100 / 5 x 4 + 4³

If the quantity is not in parentheses

We will do the power  first  4^3 = 64

100 / 5 x 4 + 64

Then we do the multiplication and division from left to right

20 *4+64

80+64

a used automobile dealership recently reduced the price of a used compact car by 10 % if the price of the car before discount was $33500 find the discount and the new price

Answers

Answer: The new price is $3350.


Answer:

$3350; $30 150  

Step-by-step explanation:

Original price = $33 500

Discount = 33 500 × 10 %

Discount = 33 500 × 0.10

Discount = $3350

New price = Original price - Discount

New price = 33 500 - 3350

New price = $30 150

a student phototcopies a drawing without realizing tht the copier is set to enlarge the image by 15%. if the height of the actual drawing is 4.25 inches, approximately how tall is the phototcopied drawing?

Answers

If an image is being enlarged by 15% you would take the base number multiply it by the percent in decimal form and add the result to the base number.

4.25*0.15=0.6275

0.6375+4.25=4.8875

Answer: 4.8875

Final answer:

To find out the height of the photocopied drawing, we first calculate 15% of the original height (4.25 inches) and add this to the original height. The photocopied drawing is approximately 4.89 inches tall.

Explanation:

The student photocopied a drawing with the copier set to enlarge the image by 15%. If the original drawing is 4.25 inches tall, the enlarged photocopied drawing would be larger by 15% of 4.25 inches.

Firstly, to find 15% of 4.25 inches, you multiply 4.25 by 0.15 (the decimal equivalent of 15%), which equals 0.6375 inches.

 

Adding this to the original height of the drawing, we get 4.25 inches + 0.6375 inches = 4.8875 inches, which is approximately 4.89 inches when rounded to two decimal places.

So, the photocopied drawing is approximately 4.89 inches tall.

17+6=23. Its true that it is B, as B is 12.17.23.

Final answer:

The next three terms in the sequence are 13, 21, and 34.

Explanation:

The given sequence is 2, 3, 5, 8.

To find the next three terms in the sequence, we need to determine the pattern.

By observing the sequence, we can see that each term is obtained by adding the two previous terms.

For example,

3 = 2 + 1,

5 = 3 + 2, and

8 = 5 + 3.

Using this pattern, the next term would be obtained by adding 8 + 5, -

8 + 5 = 13

The two terms after that would be

13 + 8 = 21 and

21 + 13 = 34.

Therefore, the next three terms in the sequence are 13, 21, and 34.

please mark brainliest


Final answer:

The two numbers are 35 and 18. We found these by solving the simultaneous equations x + y = 53 and x - y = 17, representing their sum and difference.

Explanation:

Finding Two Numbers Given Their Sum and Difference

Let's denote the two unknown numbers as x and y. According to the conditions given:

x + y = 53 (Equation 1: The sum of the two numbers)

x - y = 17 (Equation 2: The difference of the two numbers)

We can solve these two simultaneous equations to find the values of x and y.

Add the two equations:

(x + y) + (x - y) = 53 + 17

2x = 70

x = 35

Substitute x in Equation 1:

35 + y = 53

y = 53 - 35

y = 18

Therefore, the two numbers are 35 and 18.

What is the equation of the line, in standard form, that passes through (4, -3) and is parallel to the line whose equation is 4x + y - 2 = 0?

answers:
4x - y = 13
4x + y = 13
4x + y = -13

Answers

Answer:

The equation of this line would be 4x + y = 13

Step-by-step explanation:

In order to find this equation we must first find the slope of the original line. To do this, we solve the original equation for y.

4x + y - 2 = 0

4x + y = 2

y = -4x + 2

The original slope (the coefficient of x) is -4, which means the new slope will also be -4 because parallel lines have the same slope. Now, we can use this slope along with the point in point-slope form to find the equation of the line. Just plug in the numbers and solve for the coefficient.

y - y1 = m(x - x1)

y + 3 = -4(x - 4)

y + 3 = -4x + 16

4x + y + 3 = 16

4x + y = 13
