Robert sketches two rectangular prisms, A and B. Prism A's side lengths are 5 centimeters, 6 centimeters, and 7 centimeters. Prism B's side lengths were twice those of prism A's: 10 centimeters, 12 centimeters, and 14 centimeters. Robert says the surface area of prism B is twice the surface area of prism A. Is he correct? If he is not, how many times as great as prism A's surface area is prism B's surface area? Show your work.​

Answers

Answer 1

Answer:

Robert is wrong, the correct answer is 4 times greater

Step-by-step explanation:

Area is the product of two dimensions.

If each dimension is doubled, then the area becomes 2*2 = 4 times greater.

If each face is 4 times greater, then their sum will be 4 times greater.

The sum of the faces is the total surface area, therefore the B's surface area is 4 times as great as A's surface area.

A piece on a game board moves forward 8 spaces on its first turn and moves backward 3 spaces on its second turn. If the pattern continues, how many turns will it take for the piece to move at least 30 spaces? Please help me!!!

Answers

Answer:

It will take 8 turns

Step-by-step explanation:

Answer:

11 turns

Step-by-step explanation:

A piece on a game board moves forward 8 spaces on its first turn and moves backward 3 spaces on its second turn. How many space it moves for each 2 turns?

Space it moves for each 2 turns = 8-3 = 5

The question is asking for how many turns will it take to move 30 spaces, since we know that the piece will move for 5 space each 2 turns(let's call this a cycle).  

Cycle required for 30 spaces = 30/5 = 6

At this point, many will think that the no. of turns required is 6x2 = 12, but that's not the answer! Do you still remember how the cycle works? 1st up 5, 2nd down 3! On the 11th turn, the piece actually moved for 5x5 + 8 space = 33 spaces, which is greater than 30!

∴The answer is 11 turns

If q is the centroid of JKL, LN=72,JP=93, and MK=78, find each missing measure

Answers

*diagram is in the attachment below

Answer:

Step-by-step explanation:

Given:

LN = 72

JP = 93

MK = 78

Required:

LQ, QN, QP, JQ MQ, and KQ.

Solution:

Apply the centroid theorem to find each missing measure.

✔️LQ = ⅔(LN)

LQ = ⅔(72)

LQ = 48

✔️QN = ⅓(LN)

QN = ⅓(72)

QN = 24

✔️QP = ⅓(JP)

QP = ⅓(93)

QP = 31

✔️JQ = ⅔(JP)

JQ = ⅔(93)

JQ = 62

✔️MQ = ⅓(MK)

MQ = ⅓(78)

MQ = 26

✔️KQ = ⅔(MK)

KQ = ⅔(78)

KQ = 52

Which area model represents 0.4 x 0.7 = 0.28?​

Answers

Answer:

the one with pink and white at the top, and the same one with purple and blue on the bottom

Step-by-step explanation:

The area model that represents 0.4 x 0.7 = 0.28 is the first graph, with pink color, purple colour, white colour and blue color.

Which area model represents 0.4 x 0.7 = 0.28?​

The area model that represents 0.4 x 0.7 = 0.28 is determined by observing the graph with 0.4 row or column times row or column with 0.7.

The solution of the expression is calculated as follows;

0.4 x 0.7 = 0.28

So we can see that the first graph has 0.4 column and 0.7 row, creating the desired result need for the product of 0.4 and 0.7.

Thus, the area model that represents 0.4 x 0.7 = 0.28 is determined as the first graph with pink color, purple colour, white colour and blue color.

Steve bought used and new video games from a website. The new games cost $54 each and the used games cost $9 each. He spent no more than $243 on the video games and he bought no more than 7 video games. Let x represent the number of new video games, and let y represent the number of used video games. Identify an ordered pair that is a solution to the system of inequalities. Interpret the meaning of the ordered pair within the context of the problem by selecting the appropriate explanation.

Answers

Answer:

y = 3 used games

x = 4 new games

Step-by-step explanation:

54x + 9y = 243

x + y = 7   then x = 7 - y

substitute for x:

54(7 - y) + 9y = 243

378 - 54y + 9y = 243

reduce:

378 - 45y = 243

subtract 243 from each side:

135 - 45y = 0

add 45y to each side:

45y = 135

divide both sides by 45:

y = 3

x = 7 - 3 = 4

check:

3+4 = 7

7 = 7

54(4) + 9(3) = 243

243 = 243

the first one is 240

the second one is 280

the third one is 200

The answers that would be discarded would be 220, 360 and 500

Step-by-step explanation:

Hey There!

So for this problem all we have to do is plug in the hours worked and drones sold into the expression 10h+40d

For the first one we just plug in 8 for hours (because he worked 8 hours) and 4 for drones ( because he sold 4 drones )

so we would have 10(8) + 40(4)

10x8=80

40x4=160

160+80=240 So 240 would go with the first one

For the second one we plug in 4 for hours ( because he worked 4 hours) and 6 for drones ( because he sold 6 drones)

so we would have 10(4)+40(6)

10x4=40

40x6=240

240+40=280

So 280 would go with the second one

For the third one we plug in 12 for hours ( because he worked 12 hours) and 2 for drones ( because he sold 2 drones)

so we would have

12(10)+2(40)

12x10=120

2x40=80

120+80=200

so 200 would go with the third one

hope this helps :)
