A Juice Can Is 16cm Tall And Has A Diameter Of 9cm. The Ends Of The Can Are Tin And The Body Is Cardboard.

Answers

Answer 1

Answer:

a)1017.88 cm³

b)63.62 cm² (corr. to 2 d. p.)

c)452.39 cm²  (corr. to 2 d. p.)

d)579.63 cm²

Step-by-step explanation:

a) Volume = π x r x h = π x (9/2) x 16 = 1017.88 cm³

b) area of tin is used = circle = π x (9/2)² = 63.62 cm² (corr. to 2 d. p.)

c) area of cardboard is used = 2 x π x (9/2) x 16 = 452.39 cm²  (corr. to 2 d. p.)

d) total area surface = 2(63.62) + 452.39 = 579.63 cm²

The slope of the line that contains the points (2, -7) and (-2, 5) is -3. What is the y-intercept?

A. 11
B. 1
C. -1
D. -13


I trys but cant get it can i please get help?

Answers

Answer:

C. -1

Step-by-step explanation:

Find the y intercept by plugging in the slope and a given point into the equation y = mx + b. Then, solve for b:

y = mx + b

-7 = -3(2) + b

-7 = -6 + b

-1 = b

So, the y intercept is -1.

The correct answer is C. -1

Jada has time on the weekends to earn some money. A local bookstore is looking for someone to help sort books and will pay $12.20 an hour. To get to and from the bookstore on a work day, however, Jada would have to spend $7.15 on bus fare.

Which equation will represent Jada’s take-home earnings in dollars, E, if she works at the bookstore for h hours in one day.


12.20h + 7.15 = E



12.20h - 7.15 = E

7.15h + 12.20 = E


7.15h - 12.20 = E

Answers

Answer:

B

Step-by-step explanation:

Answer:

E = 12.20(h) - 7.15

h = 6.82 hours

Given:

Pay hour = $12.20 per hour

Bus fare = $7.15

1.Equation:

Assume

She has work for "h" hours

Total earning = E

So,

E = 12.20(h) - 7.15

If,

Total earning = E = $90.45

So,

E = 12.20(h) - 7.15

90.45 = 12.20(h) - 7.15

h = 6.82 hours

Please help me find the area of the triangles in the picture shown below.

Answers

Answer:

1)6

2)20

3)45

Step-by-step explanation:

a=1/2 bh

1) 4*3=12/2=6

2) 8*5=40/2=20

3)15*6=90/2=45

Answer:

1) 6

2) 20

3) 45

Step-by-step explanation:

To find the area of a triangle, use the formula [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] represents the length of the base, and [tex]h[/tex] represents the height. In the first triangle, the base length is 4 and the height is 3, so the area is 6. In the second triangle, the base length is 5 and the height is 8, so the area is 20. In the third triangle, the base length is 15 and the height is 6, so the area is 45.

1. You have a 16m by 24m rectangular area in your garden. You want to use it
to construct a swimming pool. The swimming pool will have a surrounding
foot path of 2m. If it costs $3 per square meters to tile the footpath, How
much will it cost to tile the entire footpath?
2m
2m
16 m
24 m

Answers

Answer:

Total cost of footpath = 528 m²

Step-by-step explanation:

Width of footpath is 2m.

Thus,

For longer footpath, there will be two sides. Thus; area = 2(24 + 2 + 2) × 2 = 112 m²

For shorter footpath, since the 2 longer sides have been taken care of, length remains 16m. Then area = 2(16 × 2) = 64 m²

Total area = 112 + 64 = 176 m²

cost to tile foot path is $3 per square metres.

Total cost of footpath = 176 × 3

Total cost of footpath = 528 m²
