The amount of rain the city received in July is r = 2.5 inches

Given data ,

City received 3/4 inch of rain on July 31

Now , it represents 3/10 of the total amount of rain this to received in July

So , the equation is represented as A

Now , the value of A is

( 3/10 )r = 3/4

Multiply by 10 on both sides , we get

3r = 30/4

Divide by 3 on both sides , we get

r = 30/12

r = 2.5 inches

Hence , the city received 2.5 inches of rain

The high temperature for today using a 3-day moving average is 92 degrees.

To calculate the high temperature for today using a 3-day moving average, we take the average of the temperatures from the past three days, including today.

Given the daily high temperatures in St. Louis for the last week:

92, 92, 93, 95, 95, 86, 95 (yesterday)

To find the 3-day moving average for today's high temperature, we consider the temperatures from yesterday, the day before yesterday, and three days ago.

(95 + 86 + 95) / 3 = 92

Therefore, the high temperature for today, calculated using a 3-day moving average, is approximately 92 degrees Fahrenheit, rounded to one decimal place.

Answer:

10 - 16

Step-by-step explanation:

Answer:Let's call the two numbers we are trying to find "x" and "y".

We know that the sum of these two numbers is 16, so we can write the equation:

x + y = 16

We also know that the difference between these two numbers is 27, so we can write the equation:

x - y = 27

Now we have two equations and two unknowns. We can use substitution or elimination to solve for x and y.

Using the substitution method, we can solve for y in the first equation:

y = 16 - x

Now we can substitute this expression for y into the second equation:

x - (16 - x) = 27

Simplifying this equation, we get:

2x - 16 = 27

Adding 16 to both sides, we get:

2x = 43

Dividing both sides by 2, we get:

x = 21.5

Now we can substitute this value for x into either of the original equations to solve for y:

y = 16 - x = 16 - 21.5 = -5.5

So the two numbers are 21.5 and -5.5.

The two numbers whose sum is 52 and the product is maximum are 26 and 26.

Finding the least common multiples of the denominator expressions can help. Then using the similar method as we use in the sum of fractions would give the sum of algebraic fractions.

We need to find the two numbers whose sum is 52 and the product is maximum.

So, the multiples of 52 are

2, 26, 4, 13,

So, here we can see that the sum of 26 to itself would be equal to 52.

26 + 26 = 52

The product is also maximum compared to others.

26 x 26 = 676

Therefore, the two numbers are 26 and 26.

Answer:

23 & 13

Step-by-step explanation:

23+13=36

Answer:

x = 23

y = 13

Step-by-step explanation:

Let the number be x and y.

As given,

x + y = 36 ---(i)

x - y = 10 ---(ii)

Adding eq(i) and eq(ii) we get,

2x = 46

x = 23

Now putting the value of x in eq(ii)

23 - y = 10

y = 13

So the two numbers are 23 and 13.

The length of the third side is 9.4.

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We have,

Applying Pythagorean theorem.

Third side = x

x² = 8² + 5²

8 x 8 = 64 and 5 x 5 = 25

So,

x² = 64 + 25

x² = 89

x = √89

x = 9.433

Rounding to the nearest tenth.

x = 9.4

Step-by-step explanation:

Step 1:  Find the amount Elmer's funds decreased after purchasing the rabbits:

Let x represent Elmer's funds.

Since Elmer bought five rabbits for $10 each, he lost $10 5 times.

x - (10 * 5)

x - 50

Thus, Elmer lost (spent) $50 for the 5 rabbits.

Step 2:  Find the amount Elmer's funds decreased after purchasing the  cupboards:

Since Elmer bought four cupboards for $70 each, he lost $70 4 times:

x - (50 + (70 * 4))

x - (50 + 280)

x - 330

Thus, after purchasing the rabbits and cupboards, Elmer lost $330.

Step 3:  Find the amount Elmer's funds increased after finding the twenty-dollar bill:

Since Elmer found a twenty-dollar bill, he gained $20

x - (330 + 20)

x - 310

Step 4:  Find the amount Elmer's funds increased after returning one rabbit:

Since Elmer returned one rabbit, he gained $10:

x - (310 + 10)

x - 300

Thus, Elmer's funds changed totally by -$300.

Putting all the information together, we have:

x - 10 - 10 - 10 - 10 - 10 - 70 - 70 - 70 - 70 + 20 + 10

x - 50 - 280 + 30

x - 330 + 30

x - $300

The most appropriate choice for perimeter of rectangle will be given by

It costs $76.16 to buy enough of the border to go around the room.

What is perimeter of a rectangle?

The total length of the outline of a rectangle is called perimeter of rectangle.

If the length of a rectangle is l units and breadth of a rectangle is b units, then perimeter of rectangle will be given by

                                      \(2 \times (l+b)\) units

Here,

Length of room = 20 feet

Width of room = 12 feet

Perimeter of room = \(2 \times (20 + 12)\)

                               = \(2 \times 32\)

                               = \(64\) feet

cost of 1 foot of border = $1.19

cost of 64 foot of border = $\(1.19 \times 64\)

                                         = $\(76.16\)

At the 0.05 significance level, the hypothesis test supports the claim that the mean amount of juice in the 16-ounce bottles is less than 16.3 ounces, based on the sample data and calculations.

To test the claim that the mean amount of juice in the 16-ounce bottles is less than 16.3 ounces, we can perform a one-sample t-test.

State the null hypothesis (H₀) and the alternative hypothesis (H1):

- Null hypothesis (H₀): The mean amount of juice in the 16-ounce bottles is equal to or greater than 16.3 ounces (μ >= 16.3).

- Alternative hypothesis (H₁): The mean amount of juice in the 16-ounce bottles is less than 16.3 ounces (μ < 16.3).

Choose the significance level. In this case, the significance level is 0.05.

Calculate the test statistic. We'll use the formula for the one-sample t-test:

t = (\(\bar{x}\) - μ) / (σ / √(n))

where \(\bar{x}\) is the sample mean, μ is the hypothesized mean, σ is the population standard deviation, and n is the sample size.

Sample mean (\(\bar{x}\)) = 16.14 ounces

Hypothesized mean (μ) = 16.3 ounces

Population standard deviation (σ) = 0.9 ounces

Sample size (n) = 70

Substituting these values into the formula:

t = (16.14 - 16.3) / (0.9 / √(70))

t ≈ -1.69

Determine the critical value or p-value. Since we have a left-tailed test, we'll find the critical value using the t-distribution with (n - 1) degrees of freedom (df = 69) and a significance level of 0.05. Looking up the critical value in the t-table, we find it to be approximately -1.666.

Compare the test statistic with the critical value. Since the test statistic (-1.69) is less than the critical value (-1.666), it falls in the critical region.

Make a decision and interpret the results. Since the test statistic falls in the critical region, we reject the null hypothesis. This means that there is sufficient evidence to support the claim that the mean amount of juice in the 16-ounce bottles is less than 16.3 ounces.

Therefore, at the 0.05 significance level, the claim that the mean amount of juice for all 16-ounce bottles is less than 16.3 ounces is supported.

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

\((5x+10x)+(5x+1x)\)

Answer:

y = -2x + 6

Step-by-step explanation:

Slope-intercept form: y = mx + b

Given:

Slope(m): -2

Point: (-1, 8)

To write the equation in slope-intercept form we need to find the slope(m) and the y-intercept(b).

Since we already know the slope is -2, we can move on to finding the y-intercept. To find the y-intercept, input the values of the slope and the point into the equation format and solve for b:

y = mx + b

8 = -2(-1) + b

8 = 2 + b

6 = b

The y-intercept is 6.

Now that we know the slope and the y-intercept, we can write the equation:

y = -2x + 6
