Answer:
I believe the volume would be 3.75 or 3 and 3/4
Step-by-step explanation:
To get the volume you have to multiply Length×width×height
The length is 5/2 (2.5)

The height is 3/2 (1.5)
2.5×1= 2.5
2.5×1.5=3.75 or 3 3/4

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?
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

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!
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 ∠ 7.770We can conclude that Matthew's number is less than Amelie's number.

Express 2x2 – 3x – 5 as the product of two binomial factors.
Answer:
(2x-5) (x+1)Step-by-step explanation:
Express 2x2 – 3x – 5 as the product of two binomial factors.
factorize the given expression
2x^2 – 3x – 5
2x^2 – 5x+2x – 5
x(2x-5)+ 1 (2x-5)
(2x-5) (x+1)
Hence the expression as the product of two binomial is (2x-5) (x+1)
