The volume of a cone, V(cone), is given by the following formula:

V(cone) = (1/3)Bh, where B is the area of the circular base and h is the height of the cone. The area B of the base is given by the formula B = πr², where r is the radius of the circular base; Therefore, substituting for B, the volume of a cone becomes:

The ratio of the length to the breadth to the length of a tin is 5:4:3. The bottom area of the tin is 80 square inches. What is
Vladimir [108]

Answer:

480 Cubic inches

Step-by-step explanation:

Length:Breadth:Height = 5:4:3.

Let the Length of the Tin =5x

Breadth of the Tin =4x

Since the bottom area of the tin is 80 square inches.

5x \times 4x=80\\20x^2=80\\x^2=4\\x=2

Therefore:

Length of the Tin =5 X 2 =10 inches

Breadth of the Tin =4 X 2 =8 Inches

Height of the Tin =3 X 2=6 Inches

Volume of the Tin = Length X Breadth X Height

=10 X 8 X 6

=480 Cubic inches

Her mother did not gave her enough money.
each pound of bananas costs 80 cents. 5 pounds of that is $0.8 x 5 = $4.00
each pound of apples costs $1.40. 5 pounds of that is $1.40 x 5 = $7.00
$4.00 + $7.00 = $11.00
Therefore, she needs 11 dollars to buy 5 pounds of each bananas and apples. She needs to ask her mother for 1 more dollar.

Plz help me and plz show work
Flauer [41]

Answer:

21. The slope is 50.

22. 0

23. y=50x

24. $2600

Step-by-step explanation:

21. The slope of the line is 50. Slope is defined as "rise over run". As the line increases, each segment moves up the y-axis by $50, and to the right on the x-axis 1 segment. (Work: 50 divided by 1)

22. The y-intercept is (0, 0), or simply 0. If you look at the graph you can see that the line crosses the y-axis at the origin. This makes the y-intercept equal to 0.

23. The slope tells you that the student makes $50 every week. The y-intercept is 0. Using the formula y=mx+b, an appropriate equation would be y=50x.

24. The equation found in problem 23 can me used to determine how much a student makes (y) after "x" weeks. Substitute 52 for x to solve for y. This becomes y=50(52). This can be simplified to y=2600. This means that after 52 weeks, the student will have made $2,600.
