Mathematics
1 answer:
Luda [366]3 years ago
4 0

Answer:

9

Step-by-step explanation:

KL + KJ = 17

2 + 3x + 5x - 1 = 17 add like terms

8x + 1 = 17 subtract 1 from both sides

8x = 16 divide both sides by 8

x = 2

KL = 5x - 1 replace x with 2

5*2 - 1 = 9

A milk bottle has radius 7cm and milk is filled upto a height
stich3 [128]

radius of bottle is 7 cm. height is 28 cm

so total milk in bottle is equal to total volum of bottle.

so volume of cylinder is = pi × r^2 × h

V = (22/7 )× 7×7×28 = 22×7×28

= 4312 cm^3

so volume of the milk before used to make tea is 4312 cm^3

now milk taken to make tea make height reduced to 20 cm.

so volume of the left milk in bottole is

= (22/7) × 7×7×20 = 22×7×20

= 3080 cm^3

so milk used for making tea = total milk before making the tea - total milk left in bottle after making the tea

= 4312 - 3080 = 1232 cm ^3

so volume of milk used

How do you find the area of a composite figure?
Orlov [11]

Answer:

See below.

Step-by-step explanation:

Top prism:

To find the volume of the top prism, multiply the area of the base by the height. This is 1/2 times width times height times length.

V =1/2 l*w*h =1/2* 3*2.8*8 = 33.6

To find the surface area of a prism, find the area of the triangular base and the area of each rectangular side.

Area of the base is A = 1/2 * b*h = 1/2 * 3 * 8 = 12. Since there are 2 bases, the area is 24.

Area of the rectangular side is A = b*h = 2.8*5 = 14. Since there are two, the area is 2*14 = 42.

The surface area of the prism is 24 + 28 = 52.

Bottom prism:

To find the volume of the bottom prism, multiply the width times the height times the length.

V = l*w*h = 8*2.8*4.8 = 107.52

To find the surface area of the bottom prism, find the area of the base and each side of the house.

A = 8*2.8 = 22.4

A = 8*4.8 = 38.4 which occurs twice so it has a total area of 76.8

A = 2.8*4.8 = 13.44 which occurs twice so it has an area of 26.88.

The total volume is 33.6 + 107.52 = 141.12

The total surface area is 52 + 22.4 + 76.8 + 26.88 = 178.08
