Answer:

15 feet of water spread

Step-by-step explanation:

Area of the circular pattern is 706.50 sq. feet

Area = A = π r^2 = (3.14)* r^2

706.50 = (3.14)* r^2

r^2 =  706.50 / 3.14

r^2 =  706.50 / 3.14

r = root  (225)

r = 15 feet

Answer:

15 feet

Step-by-step explanation:

The area of a circle is pi*r^2, and we're using 3.14 as pi, so we get: area= 3.14 r^2

We plug 706.50 into the equation and get:

706.50 = 3.14 r^2

Divide both sides by 3.14:

225 = r^2

Square root both sides:

15 = r

Answer:

3x(x+4)

Step-by-step explanation:

3x^2+12x

3x^2 = 3*x*x

12x = 2*2*3*x

We can factor out 3x

3x (x+2*2)

3x(x+4)

Answer:

(-2y+5x) / (3x - 2y)

Step-by-step explanation:

If we write this sentence, we have:

((-2/x) + (5/y)) / ((3/y) - (2/x))

If we do LCM in the denominators of each fraction, we have:

((-2y+5x)/xy) / ((3x - 2y)/xy)

We can cut the 'xy' in the numerator and denominator of the whole fraction:

(-2y+5x) / (3x - 2y)

The final expression we have is (-2y+5x) / (3x - 2y)

Answer:

Answer:

Expression:

[tex]\frac{9}{8}+(-\frac{1}{2})=\frac{5}{8}[/tex]

Step-by-step explanation:

We are given that

Bryce traveled distance from his home=[tex]\frac{9}{8}miles[/tex]

Bryce traveled distance back=[tex]\frac{1}{2}miles[/tex]

We have to find the expression and then simplify.

According to question

Total distance traveled by Bryce

=[tex]\frac{9}{8}+(-\frac{1}{2})[/tex]

This is required expression.

Total distance traveled by Bryce=[tex]\frac{9-4}{8}=\frac{5}{8}miles[/tex]

Hence, the total distance traveled by Bryce from his home=[tex]\frac{5}{8}miles[/tex]

Final answer:

To find the total distance Bryce walked, we add 9/8 miles to 1/2 mile, which equals 13/8 miles or simplified to 1 5/8 miles.

Explanation:

Bryce initially walks 9/8 miles from home. On his way back, he walks 1/2 mile before meeting up with his friend Mya. To describe this situation with an expression and simplify it, we add these distances together:

Total distance walked = 9/8 miles + 1/2 mile

To simplify, find a common denominator (which in this case is 8), and then add the numerators:

Total distance walked = (9/8) + (4/8)

Total distance walked = (9 + 4) / 8

Total distance walked = 13/8

Total distance walked = 1 5/8 miles

This is the sum describing the distance Bryce walked before meeting Mya, which simplifies to 1 and 5/8 miles.

Answer:

64 single-shot espressos

Step-by-step explanation:

Let's say that the cafe sold x single-shot espressos. The total number of espressos sold was 80, and 80% of that total 80 were single-shot. So, we have the equation:

x = 80% * 80

Remember that % just means "out of 100". So, 80% = 80/100:

x = (80/100) * 80 = 6400/100 = 64 single-shot espressos

Answer: the distribution is symmetrical.

Step-by-step explanation:

Answer:

The original number was 54.5.

Step-by-step explanation:

If a number is increased by 2.8%, then it is 102.8% of it's original number.

In mathematics, "of" in virtually all cases means "multiplied by".

Therefore, we do the opposite:

1. Convert to a decimal.

102.8% = 1.028

2. Divide by the decimal.

[tex]56 \div 1.028 = 54.47[/tex]

3. Round it to the nearest tenth.

54.47 rounds to 54.5.

To find the original number when increased by 2.8%, we set up and solve an equation. The original number to the nearest tenth is approximately 54.4.

To find the original number, we can set up the equation:

x + 0.028x = 56

Simplifying gives:

1.028x = 56

Dividing both sides by 1.028 gives:

x = 56 / 1.028 ≈ 54.41

So, the original number to the nearest tenth is approximately 54.4.

Answer:

Her Original PRICE WAS $117.375

Step-by-step explanation:

If the sale price is 55% of the original price of the sweatshirt, the sale price is $78.25.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

Given that, Mariah is shopping at the mall for a sweatshirt. She finds a sweatshirt that is marked down 55% off the original price of the sweatshirt is $78.25.

The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

The sale price of the sweatshirt is,

sale price = 55% of the current price

sale price =(55/100)× $78.25

sale price = $43.03

Thus, if the sale price is 55% of the original price of the sweatshirt, the sale price is $78.25.

Answer:

The correct answer is 10%.

Step-by-step explanation:

The middle school's baseball team the badgers won 20 games last year.

This year they won 22 games.

Increase in the number of wins = 22 - 20 = 2.

We need to find the percentage increase of games as compared to the last year. That is given by dividing the increase in wins divided by the wins last year multiplied by 100.

Percentage increase as compared to the last years is given by [tex]\frac{2}{20}[/tex] × 100 = 10%

There is an increase of 10% in the number of wins in this year as compared to the last year.

Answer:

95% confidence interval for the population mean weight of adult female golden retrievers is [53.01 pounds , 56.78 pounds].

Step-by-step explanation:

We are given that the weights, in pounds, of a sample of 13 adult female golden retriever dogs :

59.0, 54.1, 53.7, 51.6, 57.5, 58.7, 58.0, 53.8, 48.9, 53.9, 51.6, 55.9, and 57.4.

Firstly, the pivotal quantity for 95% confidence interval for the population mean is given by;

                         P.Q. = [tex]\frac{\bar X -\mu}{\frac{s}{\sqrt{n} } }[/tex]  ~ [tex]t_n_-_1[/tex]

where, [tex]\bar X[/tex] = sample mean weight =  [tex]\frac{\sum X }{n}[/tex]  = 54.9 pounds

            s = sample standard deviation =  [tex]\frac{\sum (X-\bar X)^{2} }{n-1}[/tex]  = 3.12 pounds

           n = sample of female = 13

           [tex]\mu[/tex] = population mean weight

Here for constructing 95% confidence interval we have used One-sample t test statistics because we don't know about population standard deviation.

So, 95% confidence interval for the population mean, [tex]\mu[/tex] is ;

P(-2.179 < [tex]t_1_2[/tex] < 2.179) = 0.95  {As the critical value of t at 12 degree

                                          of freedom are -2.179 & 2.179 with P = 2.5%}  

P(-2.179 < [tex]\frac{\bar X -\mu}{\frac{s}{\sqrt{n} } }[/tex] < 2.179) = 0.95

P( [tex]-2.179 \times {\frac{s}{\sqrt{n} } }[/tex] < [tex]{\bar X -\mu}[/tex] < [tex]2.179 \times {\frac{s}{\sqrt{n} } }[/tex] ) = 0.95

P( [tex]\bar X-2.179 \times {\frac{s}{\sqrt{n} } }[/tex] < [tex]\mu[/tex] < [tex]\bar X +2.179 \times {\frac{s}{\sqrt{n} } }[/tex] ) = 0.95

95% confidence interval for [tex]\mu[/tex] =  [tex]\bar X \pm 2.179 \times {\frac{s}{\sqrt{n} } }[/tex]

                                             = [ [tex]54.9 - 2.179 \times {\frac{3.12}{\sqrt{13} } }[/tex] , [tex]54.9 +2.179 \times {\frac{3.12}{\sqrt{13} } }[/tex] ]

                                             = [53.01 pounds , 56.78 pounds]

Therefore, 95% confidence interval for the population mean weight of adult female golden retrievers is [53.01 pounds , 56.78 pounds].
