The factory will put 441 cans of soda in 7 cases.

If each case of soda contains 7 cans of each flavor, and the factory is putting 7 cases, we can calculate the total number of cans by multiplying the number of flavors, cans per flavor, and cases.

Given:

Number of flavors = 9

Cans per flavor = 7

Number of cases = 7

To calculate the total number of cans, we can multiply these values:

Total cans = Number of flavors × Cans per flavor × Number of cases

Total cans = 9 × 7 × 7

Total cans = 441

To arrive at this answer, we multiplied the number of flavors (9) by the number of cans per flavor (7) to get the number of cans per case (63). Then, we multiplied the cans per case (63) by the number of cases (7) to obtain the total number of cans (441).

Hence, the factory will put 441 cans of soda in 7 cases.

There will be 12 slices of pizza left over, which can be expressed as 3/2 or 1 1/2 slices in fraction form.

To find out how much pizza will be left over, we need to calculate the total number of slices available and subtract the number of slices consumed by the players.

Given that there are six pizzas and each pizza has eight slices, the total number of slices available is 6 pizzas * 8 slices/pizza = 48 slices.

Since there are 36 players on the team, and each player has one slice, the total number of slices consumed is 36 slices.

To determine the remaining slices, we subtract the consumed slices from the total available slices: 48 slices - 36 slices = 12 slices.

Therefore, there will be 12 slices of pizza left over.

To express this as a fraction, we can write it as 12/1, which simplifies to 12. This means there will be 12 whole slices of pizza left over.

If you would like to express it as a fraction in its simplest form, you can write it as 12/8. By dividing both the numerator and denominator by their greatest common divisor, which is 4, we get 3/2. So, in fraction form, there will be 3/2 or 1 1/2 slices of pizza left over.

Answer:

The value of m is 0.2.

Step-by-step explanation:

Using linear regression on the given data points [(1, 4), (2, 3), (3, 5), (4, 4), (5, 5)], we obtain the following line of best fit equation:

y = 0.2x + 3.4

From this equation, we can see that the value of m (the slope of the line) is 0.2.

Therefore, the value of m in the equation y = mx + b, for the line of best fit for the given data, is 0.2.

Answer:

x=21

Step-by-step explanation:

Since the angle is the same size it is equal to 130 degrees.

First notice that

x ² + 5x + 6 = (x + 3) (x + 2)

so you can rewrite everything with a common denominator:

5 / (x ² + 5x + 6) + 7 / (x + 2) = 6 / (x + 3)

5 / (x ² + 5x + 6) + 7 (x + 3) / ((x + 2) (x + 3)) = 6 (x + 2) / ((x + 3) (x + 2))

5 / (x ² + 5x + 6) + 7 (x + 3) / (x ² + 5x + 6) = 6 (x + 2) / (x ² + 5x + 6)

(5 + 7 (x + 3)) / (x ² + 5x + 6) = 6 (x + 2) / (x ² + 5x + 6)

As long as x ≠ -3 or x ≠ -2, the denominators are never zero, so we can cancel them and be left with

5 + 7 (x + 3) = 6 (x + 2)

Solving for x is easy from here:

5 + 7x + 21 = 6x + 12

7x - 6x = 12 - 5 - 21

x = -14

ANSWER

x = 3, y = -11

EXPLANATION

We want to find the solution to the system of equations by finding when they are equal to one another.

The equations are:

y = -6x + 7

y = 13 - 8x

Now, we equate both of them:

-6x + 7 = 13 - 8x

Collect like terms:

-6x + 8x = 13 - 7

2x = 6

Divide through by 2:

x = 6 / 2

x = 3

From the first equation:

y = -6x + 7

Put the known value of x into the equation:

y = -6(3) + 7

y = -18 + 7

y = -11

Therefore, the equations are equal to each other when x = 3 and y = -11.

Answer:

To find the effective annual rate (EAR) of an account that pays interest at the nominal rate of 7% per year, compounded daily, we can use the following formula:

EAR = (1 + r/n)^n - 1

where r is the nominal annual interest rate (expressed as a decimal), and n is the number of times the interest is compounded in a year.

For daily compounding, n = 365 (since there are 365 days in a year), so we have:

EAR = (1 + 0.07/365)^365 - 1 = 0.0725 or 7.25%

To find the effective annual rate for hourly compounding, we need to adjust the value of n to account for the fact that interest is compounded more frequently. There are 365 days * 24 hours = 8,760 hours in a year, so we can use n = 8,760:

EAR = (1 + 0.07/8760)^8760 - 1 ≈ 0.0727 or 7.27%

Therefore, the effective annual rate for hourly compounding is approximately 7.27%.

Answer:

Answer:

The answer is A.

Step-by-step explanation:

The required present value needed now to get $700 after 4 years at 11% compounded monthly is $451.73.

To find the present value of $600 after 4 years at 7% compounded monthly, we can use the formula for compound interest:

Compound Interest =P(1+r/n)^rt

Substituting the given values, we get:

Compound Interest =600 (1+7/n)^4

Simplifying this equation, we get

P = 600 / 1.487

P = 451.73

Therefore, the present value needed now to get $600 after 4 years at 7% compounded monthly is $451.73.

1/4 is the fraction of the water rides

A fraction represents the parts of a whole or collection of objects e.g 3/4 shows that out of 4 equal parts, we are referring to 3 parts.

Given: the diagram shown in the image

Examining the image, you will notice that the Family ride(cyan color) divides the circle into two equal parts. That implies the Family takes half (1/2) of the whole thing.

Also, the combined total of Thrill and Water rides take the remaining half (1/2). Also, notice that the Thrill and Water rides further divide the total into two equal parts. That is:

(1/2) / 2 = 1/4

Therefore, the fraction of the water rides is 1/4
