If I understand your question correctly, you want to know how many pounds of vegetables the zoo feeds the animals a month if its a 30 day month?

In that case it would be 23 pounds times 30 days which is 690 pounds of vegetables. SO the zoo feeds the animals 690 pounds of vegetables to the animals each month.

Is that what your asking for?

To calculate the total monthly vegetable supply for the zoo animals, you multiply the daily feed amount by the average number of days in a month (23 pounds/day * 30 days/month = 690 pounds/month).

The student's question involves calculating the total amount of vegetables fed to the animals at the zoo over a month. To find this, we can set up a simple multiplication equation, where we multiply the daily food requirement by the number of days in a month. According to the question, the zoo feeds the tortoise, rhinoceros, and zebra a total of 23 pounds of vegetables a day. We are given that an average month is considered to have 30 days. So, the equation to find the total monthly vegetable supply for the animals would be:

23 pounds/day × 30 days/month = Total pounds/month

By multiplying these two numbers together, we get:

23 pounds/day × 30 days/month = 690 pounds/month

So, the zoo feeds the animals a total of 690 pounds of vegetables in an average 30 day month. If we want to express how the supply changes each month, we can write the equation as S = 23 × D, where S represents the total monthly supply and D represents the number of days in the month.

Step-by-step explanation:

Mitchel Unit rate is 15 hotdogs per minute we know this because it show 45 hotdogs in 3 minutes and 45 divided by 3 is 15 so the unit rate is 15.

Answer:

1 and 4 are correct. 2 and 3 are not.

Step-by-step explanation:

1.

When x = 0 where does the horse start?

y = 1.5*sin(0 + 0.5)*2*pi + 1.5

y = 1.5*sin(0.5*2pi) + 1.5

y = 1.5*sin(pi) + 1.5 But sin pi = 0

y = 0 + 1.5 So the horse is starting at the midpoint of it's travel.

2.

This one is a trick question. You can reason it without exact answers. At some point the sin(x + 0.5)*2pi will equal 1. When it does 1.5 * 1 + 1.5 = 3.0 At some other point sin(x + 0.5)*2pi = -1. When that happens the whole thing goes to 0. So the total of the distance traveled is 6 not three.

3.

You can figure this one out by letting x = 0.01 When it does then the value of the function is

y = 1.5*sin [(0.01 + 0.5)*2pi] + 1.5

y = 1.5*sin(0.51*2*pi) + 1.5

y = 1.5*sin(3.204424) + 1.5

y = 1.5*(- .0623) + 1.5

y = -0.9418 + 1.5

y = 1.4058 so it is going downward The value is getting smaller.

4.

The horse starts out in the middle of the pole. What  does x need to equal so that x + 0.5 = 1 ? And why 1. The answer to why 1 is that then the sine function will equal sin(2*pi)

That happens when x = 0.5 which is 1/2 a minute. If it takes 1/2 a minute to execute 1 complete cycle, then in 5 minutes the cycle will be executed 10 times. This one is correct.

Final answer:

A student who drinks 64 ounces of coffee each day consumes 182.5 gallons per year, after converting ounces to gallons (64 ounces/day × 365 days/year, then divided by 128 ounces/gallon).

Explanation:

To calculate the amount of coffee a student drinks per year in gallons, we first need to understand the relationship between ounces and gallons. We know that 1 gallon is equivalent to 128 fluid ounces. So, to find out how many gallons 64 ounces represent, we divide 64 by 128.

64 ounces per day × 365 days per year = 23,360 ounces per year.

Next, divide the total annual ounces by the number of ounces in a gallon:

23,360 ounces per year ÷ 128 ounces per gallon = 182.5 gallons per year.

Therefore, rounded to the nearest tenth, a student drinks 182.5 gallons of coffee each year.

Step-by-step explanation:

The reason it is called an "identity matrix" is that it doesn't change anything. The result is what you started with.

When the matrix A = [ [2, 3], [4, 5] ] is multiplied by the 2x2 identity matrix, the resulting matrix is still A itself: [ [2, 3], [4, 5] ].

When you multiply a matrix by the identity matrix, the result is the original matrix itself. In this case, matrix A is given as A = [ [2, 3], [4, 5] ], and you want to find A * I, where I represents the identity matrix.

The identity matrix is a square matrix with ones on the main diagonal and zeros everywhere else. In this case, since A is a 2x2 matrix, you would use a 2x2 identity matrix, which looks like:

I = [ [1, 0], [0, 1] ]

Now, when you multiply A by I:

A * I = [ [2, 3], [4, 5] ] * [ [1, 0], [0, 1] ]

You can perform matrix multiplication as follows:

[ (2*1 + 3*0), (2*0 + 3*1) ]

[ (4*1 + 5*0), (4*0 + 5*1) ]

Simplifying the calculations:

[ 2, 3 ]

[ 4, 5 ]

The resulting matrix is exactly the same as matrix A. So, A * I equals the original matrix A: [ [2, 3], [4, 5] ].

Step-by-step explanation:

28 games won

we require to calculate 80% of 35

80% = [tex]\frac{80}{100}[/tex] = 0.8

games won = 0.8 × 35 = 28

The equation is r(x) = 10x - 0.025x² where x is measured in thousands of toys produced, and r(x) is measured in thousands of dollars.

For maximum r, r'(x) = 0

It becomes: r'(x) = [tex]10-0.025\times2x=0[/tex]

= [tex]10-0.5x=0[/tex]

[tex]x=\frac{10}{0.05}[/tex]

x= 200

Hence, r(200) = [tex]10\times200-0.025\times200^{2}[/tex]

Solving it we get,

r(200) = 1000

Hence, maximum revenue the company can earn with this toy is $1000.

Answer:

Krista's have more amount by $14.05

Step-by-step explanation:

Nick's Case

Principal = $3500

Rate of interest = 11% = 0.11

Time = 2 years

Formula : [tex]A=P(1+R)^t[/tex]

[tex]A=3500(1+0.11)^2[/tex]

[tex]A=4312.35[/tex]

Krista's case

Principal = $4000

Rate of interest = 4% = 0.04

Time = 2 years

Formula : [tex]A=P(1+R)^t[/tex]

[tex]A=4000(1+0.04)^2[/tex]

[tex]A=4326.4[/tex]

Nick's amount = $4312.35

Krista's amount = $4326.4

So, Krista's have more amount

Difference =  $4326.4-$4312.35=$14.05

Hence Krista's have more amount by $14.05

If you start with 1 cheerleader in row A, then you'll have 3 cheerleaders in row B (add on 2), and then 5 cheerleaders for row C (add on another 2), etc etc.

Note how: 1+3+5 = 4+5 = 9 which is a perfect square. Also note that 36 is a perfect square.

Rule: The sum of the first positive n odd numbers is going to be equal to n^2. In the example of adding the first three odd numbers (1,3,5), we have n^2 = 3^2 = 9 as the sum

So as you can see, we'll have n = 6 rows because n^2 = 6^2 = 36 and

1+3+5+7+9+11 = 36

which is the sum of the first six positive odd numbers. So we'll have 1 cheerleader in row A, 3 in row B, 5 in row C, 7 in row D, 9 in row E, 11 in row F to have 6 rows total.

To determine the number of rows in the triangular formation, set up an equation and solve for x. The number of rows is 6.

To determine the number of rows in the triangular formation, we can set up a series of equations.

Let x be the number of rows.

The first row will have 1 cheerleader, the second row will have 3 cheerleaders, the third row will have 5 cheerleaders, and so on.

We can set up the equation: 1 + 3 + 5 + ... + (2x-1) = 36.

This is the sum of an arithmetic sequence with a common difference of 2. Solving for x, we get x = 6.

Therefore, there will be 6 rows in the formation.
