A rabbit weighs 4 pounds and 6 ounces how many ounces does the rabbit weigh

Answers

There are 16 ounces in a pound. If there are 4 pounds, then you take 16 and multiply it by 4 and then add 6.

The answer is: 70.

1lb is equal to 16oz. Multiply 16x4= 64oz. Then add 6oz on to that. 70oz is your answer.

A music school charges a registration fee in addition to a fee per lesson. Music lessons last 0.5 hour. The equation y = 40x + 30 represents the total cost y of x lessons. Find and interpret the slope and y-intercept of the line that represents this situation. Then find four points on the line.

Answers

y=mx+b M is the slope.Therefore, 40 is slope.

To find Y intercept, you substitute X for 0
So it becomes, y=40(0)+30
Solve it, y=0+30
y=30
If Y=30 x=0
Y intercept is (0,30)
x y
To find four points, you use the slope.

Final answer:

The slope of the line in the provided equation represents the cost of each music lesson, while the y-intercept represents the registration fee. These two components are used to calculate the total cost of taking 'x' number of music lessons. Examples of four points on this line include: (0,30), (1,70), (2,110) and (3,150).

Explanation:

In the equation y = 40x + 30, 'y' represents the total cost of music lessons, 'x' represents the number of lessons, 40 is the slope, and 30 is the y-intercept.

The slope, 40, means that each music lesson costs $40. This is a constant rate and doesn't change no matter how many lessons a student takes.

The y-intercept, 30, represents the registration fee that is charged in addition to the cost per lesson. This is a one-time fee that's added to the total cost of the lessons.

For example, four points on the line could be (0,30) when no classes are taken, (1,70) for one class, (2,110) for two classes, and (3,150) for three classes.

The surface area doesn't depend on the unit you use to describe it,
but the number in the description does.

Definition: 1 cm = 10 mm

Square each side: (1 cm)² = (10 mm)²

(1)² · (cm)² = (10)² · (mm)²

1 cm² = 100 mm²

So if the area is 100 cm² but you want to describe it in mm² instead,
the number will become bigger.

Answer:

C. 22

Step-by-step explanation:

Inverse Alternate Interior Angles Theorem sttes that if two lines a and b are cut by transversal f so that the alternate interior angles are congruent, then a║b.

To prove that lines a and b are parallel, equate the measures of angles 96° and (6x-36)°:

$6x-36=96\n \n6x=96+36\n \n6x=132\n \nx=22$
