Matthew wrote the number 7.707.

Amelie wrote the number 7.77.

To help compare their numbers, Amelie will write her number to three decimal places. What is Amelie's number written to three decimal places?

5th grader question

help asap

30 points!
​

Answers

Answer:

7.770

Step-by-step explanation:

Amelie originally wrote her number with only two decimal places, 7.77. This only includes the tenths and hundredths places. In order to have one more decimal place, she needs to add a zero after the last digit. Therefore, her number should be written as "7.770" because this consists of a thousandths place. With this number, she can then compare her number to Matthew's 7.707.

7.707 ∠ 7.770

We can conclude that Matthew's number is less than Amelie's number.

Maeve has 45 coins, all nickels and dimes. The total value of her coins is $3,60. How many nickels and
dimes does she have?

Answers

Answer: they have

et n = number of nickels

Let d = number of dimes

given:

(1) +n+%2B+d+=+45+

(2) +5n+%2B+10d+=+360+

-------------------

Multiply both sides of (1) by 5

and subtract (1) from (2)

(2) +5n+%2B+10d+=+360+

(1) +-5n+-+5d+=+-225+

+5d+=+135+

+d+=+27+

and, since

(1) +n+%2B+d+=+45+

(1) +n+%2B+27+=+45+

(1) +n+=+45+-+27+

(1) +n+=+18+

She had 18 nickels and 27 dimes

check:

(2) +5%2A18+%2B+10%2A27+=+360+

(2) +90+%2B+270+=+360+

(2) +360+=+360+

Step-by-step explanation:

Answer:18 nickels 27 dimes

Answer:

I believe the volume would be 3.75 or 3 and 3/4

To get the volume you have to multiply Length×width×height

The length is 5/2 (2.5)

The width is 1

The height is 3/2 (1.5)

2.5×1= 2.5

2.5×1.5=3.75 or 3 3/4
