Answer:

The answer is the option B

The number of lawns mowed

Step-by-step explanation:

we have

y=\$15x-\$95

In this linear equation

y-----> is the total profit (in dollars)

x---->  is the number of lawns mowed

\$15 -----> Earn per lawn

\$95 -----> Cost of the supplies

Use the data to create a scatter plot\<br> forks: 2,4,6,8,10,12<br> spoons: 10,6,4,1,0,2
Len [333]

Answer:

The resulting scatter plot is attached below :

To plot the required scatter plot :

We first take forks on the x - axis and the spoons on the y - axis

Now we arrange the given data in the form of x and y coordinates

Hence, the data becomes :

(2, 10)

(4, 6)

(6, 4)

(8, 1)

(10, 0)

(12, 2)

Now, We plot these points on the graph and get the required scatter plot for the given data.

[Systems of equations] (/20) 1. Suppose the coefficient matrix of a system of linear equations has a pivot position in every row
Marina86 [1]

Answer:

The system is consistent because the rightmost column of the augmented matrix is not a pivot column.

Step-by-step explanation:

It is given that the coefficient of the matrix of a linear equation has a pivot position in every row.

It is provided by the Existence and Uniqueness theorem that linear system is said to be consistent when only  the column in the rightmost of the matrix which is augmented is not a pivot column.

When the linear system is considered consistent, then every solution set consists of either unique solution where there will be no any variables which are free or infinitely many solutions, when there is at least one free variable. This explains why the system is consistent.

For any m x n augmented matrix of any system, if its co-efficient matrix has a pivot position in every row, then there will never be a row of the form [0 .... 0 b].

A cylinder fits inside a square prism as shown. For every cross section, the ratio of the area of the circle to the area of the
kolbaska11 [484]

Answer:

Volume of cylinder = \pi r^2h

Step-by-step explanation:

Given : A cylinder fits inside a square prism.

To find : The volume of cylinder

Solution : Refer the attached graph.

Area of circle = \pi r^2

Area of square = s^2

Side of square = diameter of circle= D^2

Diameter = 2r

∴ Area of square=  2r^2=4r^2

\frac{Area of circle}{Area of Square}=\frac{\pi r^2}{4r^2}=\frac{\pi}{4}

Area of circle is \frac{\pi }{4}  of area of square.

Volume is always = area × height

Volume of prism = Area of square × h = 4r^2h

Volume of cylinder = Area of circle × h = \pi r^2h

Now, rate

\frac{Volume of cylinder}{Volume of prism}=\frac{\pi r^2h}{4r^2h}=\frac{\pi}{4}

⇒Volume of cylinder is  \frac{\pi }{4}  of Volume of prism.

Volume of Cylinder =\frac{\pi }{4}\times Volume of prism

Volume of cylinder = \frac{\pi }{4}\times 4r^2h

Volume of cylinder = \pi r^2h

B. A square has a side length of 5 feet. <br> What is the length of each side of the square
densk [106]

Answer:

5 ft.

Step-by-step explanation:

A square is a shape comprised of all equal side lengths. Therefore, if we are given that the square has a side length of 5 feet, then every side's length would also be 5 feet.

3. A recipe calls for 2 cups of sugar to make 2 dozen cookies. Use the proportion to calculate how much sugar is needed to make
vova2212 [387]

Answer:

c. 6 cups

Step-by-step explanation:

The proportion is 1 cup of sugar for 1 dozen cookies (1/1). So if you multiply the denominator by 6 you must multiply the numerator by 6, and 6*1=6. Therefore you need 6 cups of sugar to make 6 dozen cookies.
