Answer 1
Answer: Hey,

ok so the area of a rectangle is the product of the two sides. One side is the height of the can, the other side is the perimeter of the circle, since the label wraps once around the can. So the area of the rectangle is (2 pi r)* h. Add those two parts together and you have the formula for the surface area of a cylinder.

so To find the surface area, first multiply the length by the width to find the area. Since a cube is made up of six perfect squares, multiply the are aby six. That each measure four. Plug four into the formula to find the surface area

So the formula would be SA=2(LW+LH+WH

so area a^2+4=98^

So it is C 

h
Answer 2
Answer: ok
prism so 3 pairs of congruent sides thtat are oposite of each other
areas of each are
LW, WH, LH
(L=legnth,W=width,H=height and LW means L times W)

come in pairs
SA=2LW+2WH+2LH
undsitribue for ease
SA=2(LW+WH+LH)

L=4
W=3
H=5
sub
SA=2(4*3+3*5+4*5(
SA=2(12+15+20)
SA=2(47)
SA=94 cm^2

answer is C

Yasmine is serving ice cream with the birthday cake at her party.She has perchased 19 1/2 pints of ice cream.She will serve 3/4 of a pint to each guest. How many guests can be served ice cream? Will there be any ice cream left?Justify your thinking

Answers

The number of guests that will be served ice cream is 26 guests and there will be no ice cream left.

The total number of ice cream purchased by Yasmine at her party is:

\mathbf{=19 (1)/(12) \ pints}

If each guest gets served with 3/4 pints, then the number of guests that will receive the shared amount of pints is:

\mathbf{= (3)/(4) \ pints}

∴

The number of guests that can be served ice cream now is:

\mathbf{= (19 (1)/(12) \ pints)/( (3)/(4) \ pints)}

\mathbf{= ( (39)/(2) \ pints)/( (3)/(4) \ pints)}

\mathbf{= { (39)/(2) }* { (4)/(3)}}

\mathbf{= { (13)/(1) }* { (2)/(1)}}

= 26 guests

Therefore, we can conclude that the number of guests that will be served ice cream is 26 guests and there will be no ice cream left.

HELP ME PLEASE!!!!!!!!!!!!!!!!!!!!Which of these shows the result of using the first equation to substitute for y in the second equation, then combining like terms? y = 2x 2x + 3y = 16
A. 8x = 16
B. 4x = 16
C. 5x = 16
D. 5y = 16

Answers

I got (A)
This is my answer

Final answer:

By substituting y = 2x into the second equation and combining like terms, we get the equation 8x = 16.

Explanation:

This question is from the field of Algebra. You are asked to substitute the first equation into the second equation, then simplify by combining like terms. Substituting y = 2x from the first equation into the second equation 2x + 3y = 16, we replace y with 2x, thus transforming the second equation into 2x + 3(2x) = 16. Distributing the 3 to the 2x within the parentheses gives us 2x + 6x = 16. By combining the like terms on the left side, we get 8x = 16 which is option A.

These cuboids are made from small cubes. Write how many small cubes there are in each cuboid

Answers

The number of small cubes in each cuboid is:

(a) 3, b) 6, c) 27, and d) 16.

Given are four cuboids.

It is required to find the number of small cubes that are used to make these cuboids.

a) There are only 3 small cubes.

b) There is only one step of cubes.

Number of cubes = 3 + 3 = 6

c) There are 3 cubes arranged horizontally and 3 cubes arranged vertically through each surface.

Number of cubes in one step = 3 × 3 = 9

There are 3 steps like that.

So, total number of cubes = 3 × 9 = 27

d) There are 4 cubes in the horizontal position.

And there are 4 cubes going down.

Total number of cubes = 4 × 4 = 16

Which equation can pair with 3x + 4y = 8 to create a consistent and independent system?

Answers

There isn't any choices given in this problem but I can give you a tip to answer these kinds of problem. When you say independent, it means that the equation cannot be algebraically altered to result to 3x + 4y = 8. So the equation 6x + 8y = 16 is not an independent equation since when you divide each side by 2 it will result to 3x + 4y =8. You get the idea. 

Answer:

6x - 3y = 2
