Answer:

10

Step-by-step explanation:

okay so if he has 2 dogs and he feeds each dog 250 grams twice a day

if he buys a 10 kilo bag, how many days will it last?

so first off, convert the 250 grams into kilos. which is 0.25

0.25 × 4 = 1 kilo

4 is the amount of times he feeds the dogs.

so in reality, it should take 10 days.

The number of days will the bag last is 10 days.

Given that,

Based on the above information, the calculation is as follows:

Here first we have to convert the 250 grams into kilos so it should be 0.25

And, there is no of times the dog feed is 4

So, it should be 1 kilo

And, there is the purchase of 10 kilos

Therefore, we can conclude that The number of days will the bag last is 10 days.

The distance between the point where the cable is 1.44 inches above the roadway and the base of the nearest tower is : [tex]\[\(28 \text{ inches}}\][/tex].

To find the distance between the point where the cable is 1.44 inches above the roadway and the base of the nearest tower, we need to understand the mathematical model for the suspension bridge cable. This cable typically forms a parabolic shape.

Let's establish our coordinate system:

- Place the origin [tex]\((0, 0)\)[/tex] at the lowest point of the cable.

- The towers are at [tex]\(x = -40\)[/tex] inches and [tex]\(x = 40\)[/tex] inches since they are 80 inches apart.

- The height of the towers is 16 inches.

The equation of the parabola can be written in the vertex form [tex]\(y = ax^2\)[/tex] since the vertex is at the origin [tex]\((0, 0)\)[/tex].

At the position of the towers (x = ±40 inches), the cable is 16 inches high:

[tex]\[y(40) = 16\][/tex]

[tex]\[a(40)^2 = 16\][/tex]

[tex]\[1600a = 16\][/tex]

[tex]\[a = \frac{16}{1600} = \frac{1}{100}\][/tex]

So, the equation of the parabola is:

[tex]\[y = \frac{1}{100}x^2\][/tex]

We need to find the point where the cable is 1.44 inches above the roadway:

[tex]\[\frac{1}{100}x^2 = 1.44\][/tex]

[tex]\[x^2 = 1.44 \times 100 = 144\][/tex]

[tex]\[x = \pm\sqrt{144} = \pm 12\][/tex]

Therefore, the points where the cable is 1.44 inches above the roadway are [tex]\(x = 12\)[/tex] inches and [tex]\(x = -12\)[/tex] inches.

The distance from [tex]\(x = 12\)[/tex] inches to the nearest tower at [tex]\(x = 40\)[/tex] inches is:

[tex]\[40 - 12 = 28 \text{ inches}\][/tex]

Similarly, the distance from [tex]\(x = -12\)[/tex] inches to the nearest tower at [tex]\(x = -40\)[/tex] inches is:

[tex]\[-12 - (-40) = 28 \text{ inches}\][/tex]

Thus, the distance between the point where the cable is 1.44 inches above the roadway and the base of the nearest tower is:

[tex]\[\boxed{28 \text{ inches}}\][/tex]

She would make $573.5 in a work if she sold $4,700 worth of merchandise

Step-by-step explanation:

The given is:

We need to find how much she would make in a work week

∵ Mae Ling earns a weekly salary of $315

∵ She earns a 5.5% commission on sales

∵ She sold by $4,700 in that week

- Add $315 to the product of 5.5% and $4,700

∴ She made = 315 + (5.5% × 4,700)

∵ 5.5% = 5.5 ÷ 100 = 0.055

∴ She made = 315 + (0.055 × 4,700)

∴ She made = 315 + 258.5

∴ She made = 573.5

She would make $573.5 in a work if she sold $4,700 worth of merchandise

Answer:

Cost per ounce = $0.07 (7 cents per ounce)

Step-by-step explanation:

Each container is 7.8 ounces and there are 24 of them in a case.

Total weight in ounce of the case is:

7.8 * 24 = 187.2 ounces

It costs $12.99 for the case, which contains 187.2 ounces. We find the cost per ounce of yogurt by dividing the total cost by total ounces in the case.

12.99/187.2 = 0.0693

Rounded to nearest cent (2 decimal places), that would be:

Cost per ounce = $0.07 (7 cents per ounce)

The unit price of the Greek yogurt is $0.07 per ounce.

To calculate the unit price, we need to divide the total cost of the case by the total number of ounces in the case.

First, we determine the total number of ounces in the case by multiplying the number of containers by the ounces per container:

[tex]\[ 24 \text{ containers} \times 7.8 \text{ ounces per container} = 187.2 \text{ ounces} \][/tex]

Next, we divide the total cost of the case by the total number of ounces to find the cost per ounce:

[tex]\[ \frac{\$12.99}{187.2 \text{ ounces}} \approx \$0.0693 \text{ per ounce} \][/tex]

Finally, we round this to the nearest cent, which gives us:

[tex]\[ \$0.0693 \text{ per ounce} \approx \$0.07 \text{ per ounce} \][/tex]

Therefore, the unit price of the Greek yogurt, rounded to the nearest cent, is $0.07 per ounce.

Answer:

[tex]\$ 199[/tex]

Step-by-step explanation:

Given: Maria spent $2388 for natural gas, last year.

Maria chooses to use balance billing process to pay this year´s gas bill.

Balance billing is a billing practice, where provider bill you the difference between total cost and allowed amount. It can be paid partially or monthly. It generally in practice for medical billing as healthcare bill are generated for difference between total cost and amount which is paid through insurance.

Now, lets find out monthly bill paid by Maria.

We know there are 12 months in a year.

∴ Monthly payment= [tex]\frac{\$ 2388}{12} = \$ 199[/tex]

∴Maria will pay $199 monthly as her gas bill this year.

Maria's monthly payment for natural gas this year using balance billing will be $199.

Step 1

Balance billing is a method where a utility company estimates the annual energy usage and divides it into equal monthly payments. To find Maria's monthly payment for natural gas this year, we divide the total amount she spent last year by 12 months.

Total amount spent last year = $2,388

Step 2

Monthly payment this year = Total amount spent last year / 12 months

[tex]\[ \text{Monthly payment} = \frac{2388}{12} = 199 \][/tex]

Maria's monthly payment for natural gas this year, using balance billing, will be $199, calculated by dividing the total amount she spent last year by 12 months.

Answer:

x = 2y + 6

Step-by-step explanation:

2x - 4y = 12

2x = 4y + 12

x = 2y + 6

To solve for 'X' in the equation 2x - 4y = 12, isolate 'X' by adding 4y to both sides, resulting in the equation 2x = 4y + 12. Further, divide the entire equation by 2 to get X = 2y + 6. The final value of 'X' would depend on the value of 'Y'.

To solve for X in the equation 2x - 4y = 12, we can proceed in the following manner:

Isolate X on one side of equation. In order to do this, we add 4y to both sides of the equation, thus changing the equation to 2x = 4y + 12.

Now, to solve for X, we need to divide the entire equation by 2. Therefore, the final equation is ready: X = 2y + 6.

Thereby, you have now solved for 'X' in the equation. Kindly note that as there is a 'y' variable involved as well, the final value of 'X' would depend on the value of 'Y'.

Answer:

125 cubic inches

Step-by-step explanation:

The formula for the volume of a cube is:

[tex]V=a^3[/tex],

Where V is volume and a is edge length. Let's substitute the edge length of 5 from the problem into this formula.

[tex]V=5^3[/tex]

Now we can simplify. I will rewrite 5 cubed as 5*5*5 for simplicity.

[tex]V=5*5*5[/tex]

[tex]V=125[/tex]

So we have our volume, 125, but what does this mean? We have to figure out the units. Recall that our original unit was inches, thus the final answer is in inches. However, 125 inches does not make much sense, as we are dealing with volume, and not a line or distance. 125 cubic inches is the answer we are looking for, as cubic inches is the unit for volume deriving from inches.

The volume of a block of cheese is 125 in³.

To calculate the composite function (f ∙ g)(-1) for the functions f(x) = x² + 3 and g(x) = 4x - 3, we first find g(-1) which is -7, and then calculate f(-7) which results in 52.

To find the composite function (f ∙ g)(x), we first apply the function g to x, and then apply the function f to the result of g(x). In this case, first find g(-1) and then apply f to that result.

Initialize with g(-1), which is 4(-1) - 3. Simplifying that, we get -4 - 3, which equals -7.

Now, take the result of g(-1), which is -7, and input it into f(x) to get f(g(-1)). Thus, f(-7) = (-7)² + 3. Calculating this gives us 49 + 3, which equals 52. Therefore, (f ∙ g)(-1) = 52.

Answer:

24,393 subscribers

Step-by-step explanation:

This is exponential decay problem. The formula for exponential decay is:

[tex]F=P(1-r)^t[/tex]

Where

F is the future value (what we are looking for, in 7 years)

P is the present amount (that is 51,000)

r is the rate of decrease per year (r = 10% = 10/100 = 0.1)

t is the time, in years (t = 7)

Now substituting, we get:

[tex]F=P(1-r)^t\\F=51,000(1-0.1)^7\\F=51,000(0.9)^7\\F=24,393.14[/tex]

Rounding to nearest whole number,

Number of subscribers after 7 years = 24,393 subscribers

Using the exponential decay formula, a magazine with an initial 51,000 subscribers will have approximately 24,393 subscribers left in 7 years if subscriptions decline by 10% annually.

The question is asking to predict the number of magazine subscribers after a period of 7 years, assuming a 10% annual decline. To calculate this, we can use the formula for exponential decay, which is A = P(1 - r)^t, where A is the amount after time t, P is the initial principal amount (51,000 subscribers), r is the rate of decline (10% or 0.10), and t is the time in years (7 years). Calculating this, we get:

Now, calculate the value of A:

A = 51,000(1 - 0.10)^7

A = 51,000(0.90)^7

A = 51,000(0.4782969)

A ≈ 24,393 subscribers (after rounding to the nearest whole number).

Therefore, if the magazine subscriptions continue to decline at a rate of 10% per year, the magazine is predicted to have approximately 24,393 subscribers in 7 years.
