Step-by-step explanation:

If Marco wants to set up 12 small turbines with 3 blades each. If 4 wind turbines blades cost $79.64 then $716.76 costs for all blades.

Two or more expressions connected with an equal sign is called ad equation.

Given Marco wants to set up 12 small turbines with 3 blades each. If 4 wind turbines blades cost $79.64, then we have to find the cost of all blades.

Each turbine has 3 blades, so for 12 tubines we have

3×12=36 blades.

If 4 blades cost is  $79.64, then we have to find cost of 36 blades.

Let y be the cost of 36 blades.

4 /36= 79.64/y

Use cross multiplication,

4 * y = 36 * 79.64

4y = 2,867.04

y=716.76

Therefore 36 blades cost is $ 716.76.

Answer:

The domain of the function is {0,1,2,3,4} and the range of the function is {$33, $44, $55, $66, $77}

Step-by-step explanation:

Consider the provided information.

Sarah has sold $33 worth of tickets sales to the comedy show. She has 4 tickets left to sell at $11 per hour.

First write the function as shown.

Let the number of tickets are x and she already sold $33 worth of tickets.

Therefore the function is: [tex]f(x)=11t+33[/tex]

For t=0

[tex]f(0)=11(0)+33=33[/tex]

For t=1

[tex]f(1)=11(1)+33=44[/tex]

For t=2

[tex]f(2)=11(2)+33=55[/tex]

For t=3

[tex]f(3)=11(3)+33=66[/tex]

For t=4

[tex]f(4)=11(4)+33=77[/tex]

Hence, the domain of the function is {0,1,2,3,4} and the range of the function is {$33, $44, $55, $66, $77}

Answer:

C.

Step-by-step explanation:

The ordered pair which represents the point on the line y = 2x + 1 is C. (-1, -1).

Coordinates are the set of points in a geometrical plane or space, which is used to denote the exact point in the coordinate plane or space.

Given equation is y = 2x + 1.

We have to substitute each of the points in the line if the equation holds or not.

A. (0, 3)

2x + 1 = 0 + 1 = 1 ≠ 3

B. (2, 1)

2x + 1 = 4 + 1 = 5 ≠ 1

C. (-1, -1)

2x + 1 = -2 + 1 = -1

D. (1, 2)

2x + 1 = 2 + 1 = 3 ≠ 2

Hence the point on the line is C. (-1, -1).

The number of batches you can make if you use all the sugar is 12.61 batches.

The cost of sugar used per batch is $0.28.

A 4-pound bag of sugar = 454 one-teaspoon

Sugar used for a batch of muffins = ¾ cup

If 1 cup = 48 teaspoons

3/4 cup = 3/4 × 48

= 36 teaspoons

Number of batches to make = 454 one-teaspoon / 36 teaspoons

= 12.61 batches

Cost of sugar teaspoons= 3.49/454

= $0.007687224669603 per teaspoon

Cost of sugar per batch = 0.007687224669603 × 36

= $0.276740088105726 per batch

Hence, the cost of sugar used per batch is approximately $0.28

A 4-pound bag of sugar contains 454 one-teaspoon servings and costs $3.49. A batch of muffins uses ¾ cup of sugar. How many batches can you make if you use all the sugar? What is the cost of sugar for each batch? (1 cup = 48 teaspoons)

To find out how many batches of muffins can be made and the cost per batch, convert the total servings of sugar to cups, then divide by the amount of sugar used per batch, and finally, divide the total cost by the number of batches. which results in approximately $0.29 per batch.

The subject of this question is Mathematics, and it appears to be at the High School level due to the application of ratios, conversions, and basic algebraic skills to solve real-world problems.

Calculating Batches of Muffins from a Sugar Bag

Firstly, we determine the total amount of sugar in the bag in terms of cups. Since 1 teaspoon is equivalent to 4 grams of sugar, and we have 454 servings, we multiply 454 by 4g to get 1816g of sugar in total. To convert grams to cups (given 1 cup of sugar is 200g), we divide 1816g by 200g/cup, which gives us 9.08 cups.

Since a batch of muffins uses 3/4 cup of sugar, we divide the total cups of sugar by 3/4 to find the number of batches. 9.08 cups divided by 3/4 cups per batch results in approximately 12.1 batches; however, since you can't make a partial batch with the remaining sugar, it is safe to say you can make 12 full batches. To find the cost per batch, divide the total cost of the bag ($3.49) by the number of batches (12), which results in approximately $0.29 per batch.

The product of nine and the sum of a number Z and four can be written as 9(Z + 4). For example, if Z = 5, then the expression becomes 9(5 + 4), which equals 81.

The product of nine and the sum of a number Z and four can be written as 9(Z + 4).

For example, if Z = 5, then the expression becomes 9(5 + 4), which equals 9(9) = 81.

So, the product of nine and the sum of a number Z and four is 9(Z + 4), where Z represents any number.

[tex]\texttt{Submarine's depth relative to sea level after the first minute = }-\frac{4}{15} miles[/tex]

Step-by-step explanation:

Starting at sea level, a submarine descended at a constant rate to a depth of −4/5 mile relative to sea level in 3 minutes.

Total time = 3 minutes

[tex][tex]\texttt{Total depth descended in 3 minutes = }-\frac{4}{5}miles[/tex][/tex]

We need to find what was the submarine's depth relative to sea level after the first minute,

[tex]\texttt{Depth descended in per minute = }-\frac{\frac{4}{5}}{3}=-\frac{4}{15}miles[/tex]

[tex]\texttt{Submarine's depth relative to sea level after the first minute = }-\frac{4}{15}\times 1=-\frac{4}{15} miles\\\\\texttt{Submarine's depth relative to sea level after the first minute = }-\frac{4}{15} miles[/tex]

Jessica can fill 7 glasses with water, by dividing the total amount of water ([tex]4\frac{1}{5}[/tex] cups) by the amount that each glass holds ([tex]\frac{3}{5}[/tex] cup).

The question asks us to determine how many glasses Jessica can fill with water when each glass holds [tex]\frac{3}{5}[/tex] cup of water and she has 4 1/5 cups of water in total. To solve this, we need to divide the total amount of water by the amount each glass holds.

Firstly, we need to convert the mixed number 4 1/5 cups to an improper fraction. This is done by multiplying the whole number by the denominator and adding the numerator, like this: (4 times 5) + 1 = 21, so 4 1/5 cups is the same as [tex]\frac{21}{5}[/tex]cups.

Next, we divide the total amount of water (21/5 cups) by the amount each glass holds ([tex]\frac{3}{5}[/tex] cup), which can be written as a fraction division problem:

[tex]\frac{\frac{21}{5} }{\frac{3}{5} }[/tex] = [tex]\frac{21}{5}[/tex] x [tex]\frac{5}{3}[/tex] = [tex]\frac{21}{3}[/tex] = 7

So, Jessica can fill 7 glasses with water.
