A) In this case, the constant of proportionality is $0.59, as this remains the same, regardless of the different quantities.
B) For this, you simply have to multiply $0.59 by 25, giving you $14.75.
If you are looking at this equation, it will be in the form of y=kx, where k and x are constants.<span />

a rectangular sheet is 62cm long and 42cm wide from each of its corners a square of side 6cm is cut out and an open box is made

Alla [95]

Answer:

The volume of rectangular box is 9,000 cubic centimeters

Step-by-step explanation:

Given as :

The length of the rectangular sheet = L = 62 cm

The width of the rectangular sheet = B = 42 cm

Let The volume of rectangular box = v cubic centimeters

From each corner of sheet a square of 6 cm is cut out and an open box made

So, The length of box = L' = (L - 6 - 6)

i.e L' = (62 - 6 - 6)

Or, L' = 50 cm

Or, Length of the box = 50 cm

And The width of the box = B' = (B - 6 - 6)

i.e B' = (42 - 6 - 6)

Or, B' = 30 cm

Or width of the box = 30 cm

And,

The height of the box = H = 6 cm

∴ volume of rectangular box = Length of box × Breadth of box × Height of box

i.e v = L' × B' × H

Or, v = 50 cm × 30 cm × 6 cm

Or, v = 9,000 cm³

So, The volume of rectangular box = v = 9,000 cm³

Hence, The volume of rectangular box is 9,000 cubic centimeters Answer

The volume of a cube is 27 cubic meters. what is its surface area in square meters?

erma4kov [3.2K]

To find the answer, take the measurement of an edge of the cube, multiply it by 6, and then square that number.

Ex:

Edge = 16

Faces in 1 cube = 6

6 * 16 = 96

96^2 (which is just 96 * 96)= 9,216

I hope this helps! :)

Based on one of the Triangle Congruence Postulates, the two triangles are shown are congruent

tankabanditka [31]

Answer:

true

Step-by-step explanation:

all the sides match up. One side (the base) is shared which means they are the same length. The triangle at the top has a single hash on a side and so does the bottom one. This means they are the same length. The same thing occurs with the last remaining sides, they are congruent because they both have two hash lines. Since all three sides of both triangle add up, the triangles ARE CONGRUENT.
