A drawing of the Eiffel Tower in Paris used the scale of 2 cm = 5 m. If the height of the tower in the drawing measures 120.4 cm, what is the actual height of the Eiffel Tower?

Answer Choices
48.16 meters
310 meters
301 meters
602 meters

Answers

301 meters

Since 2cm=5m you would have to divide 120.4 by 2 to get 60.2 and times it by 5 to get 301

Answer:301m

Step-by-step explanation:120.4/2=60.2 60.2*5=301

it’s asking for the square root, meaning what number can multiply by itself to equal 49.

for this I would just start guessing and then you’ll eventually get it.

a guess could be 6*6, which is 36

meaning that it is higher, so let’s check 7.

7*7 equals 49

so, the answer is 7

I know another person already answered but I hope this explanation helps :)
7•7=49 so the answer is 7

What is the GCF?

Answers

Answer:

GCF is 18 and Factor is: 18(x-2)

Step-by-step explanation:

To Factor 18x-36, you want to find the GCF. So the GCF here is 18. So let's spilt 18 out of each term.

18x+18(-2)

18(x-2)

So the factoring answer is 18(x-2)

The GCF is 18.

Answer:18

If the surface area of the rectangular prism is 224 cm 2, what is the height?

Answers

Answer:

12 cm

Step-by-step explanation:

hope this helps!

We have to work backwards,

so 4*4*x = 224
(* is times, x is the variable for height)

first we can simplify 4*4 =16
then,

16*x = 224

then we solve

we divide both sides by 16

16x/16 = 224/16

16 cancels out while 224/16 is 14

x= 14

Do 5.8 and 5.08 have the same value? In a complete sentence, explain why or why not?

please help I can't figure it out

Answers

Answer:
no they do not
Step-by-step explanation:
5.8 is different than 5.08 because when you do 5.8 eight is in the tens place and the eight in 5.08 is in the hundreds place

Answer:

No, they don't have the same value.

Step-by-step explanation:

5.8 has no zero but 5.08 has one zero.

5.8 is more significant than 5.08 because when a 0 is added in the front, it makes the number smaller than before. The more zeros you put in front of the number, the smaller it will get.

Ryan’s gas tank is 1/2 full. After he buys 6 gallons of gas, it is 7/10 full. How many gallons can the gas tank hold

Answers

Answer:

30 gallons

Step-by-step explanation:

1/2 + 2/10 = 7/10

2/10 = 6 gallons

2/10 divided by 2 = 1/10

1/10 = 3 gallons

3 gallons x 10 = 30 gallons on 10/10 tank full

Answer: 30 gallons. If it’s half way full (5/10) and it goes up 2/10 with 6 gallons, that means every 1/10 is 3 gallons and 3•10= 30

*-7
07/1

Answers

answer: 1/7

the formula for slope is rise over run, or y1-y2 divided by x1-x2. we can choose either number as y1 or y2 but it needs to stay consistent with x

so let’s plug in from your table.

0-1 divided by -7 -0
(you could also do 1-0 divided by 0-(-7))

-1/-7 which equals 1/7

so, your slope is 1/7

216 Divided by 31 (Please include the remainder) :D

Answers

6 but the remaining is 39
216 divided by 31 (long division explanation)


2 divided 31 you can’t do so 0

21 divided 31 you cant do so 0


216 divided 31 is 6
6 times 31 is 186
So 216-186=30

You can’t do 30 times 31 so 0
Then bring down a 0 to 30 so it’s 300
Then 300 divided by 31 is 9
So 31 times 9 is 217

300-217= 83
83 divided by 31 is 2
31 times 2 is 62
83-62=21


21 divided by 31 you can’t do so add a 0
210 divided by is 6
31 times 6 was 189
210-189=21

what is the product of -16 x -5 x -11?
please give an answer and explanation

Answers

Answer: -880

Step-by-step explanation:

This is based on the fact that 2 negatives equals a positive and 1 negative + 1 positive equals a negative.

First, you would multiply two of the three numbers, I did -5 * -11 as it seemed like the easiest. Two negatives makes a Positive so that's: -5 * -11 = 55. Now you can do 55 * -16. One Negative and One Positive makes a Negative so the answer is -880. You can use column method or whatever method you use to multiply two digit numbers but I would always think of it as two different equations.

Hope this is an okay explanation!

P.S. This is a video explanation of the product of three negatives if you need it: https://youtu.be/vxWlFF__nT0 credit goes to the creator of this video.
