Answer:

Both the lines shown by above two equations have same slope = 3 i.e. the lines are parallel to each other i.e. they don't intersect each other hence the given system of linear equations has no solution .

Answer:

x = -1; y = 1

Step-by-step explanation:

3x - y = -4

x + y = 0

Since you have -y and +y in the two equations, you can add them and eliminate y.

Add the equations.

4x = -4

x = -1

Now substitute -1 for x in the second equation and solve for y.

-1 + y = 0

y = 1

In a circle of radius 10 cm, a sector has an area of 40 (pi) sq. cm. What is the degree measure of the arc of the sector?
Rashid [163]

Answer:

144°

Step-by-step explanation:

First, find the area of the circle, with the formula A = \pir²

Plug in 10 as the radius, and solve

A = \pir²

A = \pi(10²)

A = 100\pi

Using this, create a proportion that relates the area of the sector to the degree measure of the arc.

Let x represent the degree measure of the arc of the sector:

\frac{40\pi }{100\pi } = \frac{x}{360}

Cross multiply and solve for x:

100\pix = 14400\pi

x = 144

So, the degree measure of the sector arc is 144°

The video club to which Lin belongs allows her to receive one free DVD for every three DVDS she rents. If she pays $3 for each D
Nesterboy [21]

Answer:

12

Step-by-step explanation:

Given:

On every 3 DVDs she rents, 1 DVD is received for free

Rent of each DVD = $3

Total amount paid = $114

Now,

The total number of DVDs she took on rent = \frac{\textup{Total amount paid}}{\textup{Rent of each DVD}}

or

The total number of DVDs she took on rent = \frac{\textup{114}}{\textup{3}}

or

The total number of DVDs she took on rent = 38

also,

For every 3 DVDs she gets 1 Free DVD

thus,

For every 1 DVD she gets \frac{\textup{1}}{\textup{3}} free DVD

therefore,

For  38 DVD she gets \frac{\textup{38}}{\textup{3}} free DVD

or

she gets 12.67 DVDs free

Since,

the DVDs cannot be given in fraction

Hence she will get 12 free DVDs

At the car show Inez saw a truck wheel shaped like a circle with a radius of 3 ft. She wants to know the area of the truck wheel
Nadusha1986 [10]

Answer:

28.27ft^2

Step-by-step explanation:

To solve this problem, we can use the area of a circle formula:

A=\pi r^2

<em>A = area</em>

<em>r = radius</em>

Lets plug the values into the equation:

A=\pi (3^2)     Calculate 3^2

A=\pi (9)       Multiply \pi and 9 together

A=28.27

The area of the truck wheel is 28.27ft^2
