USPshnik [31]

Question:

Three students were working on 630,000÷700 in math class.

a. Desiree finds the quotient is 9,000 and Micah finds the quotient is 900.

Determine which student found the correct quotient.

b. Delilah finds her answer is 90, but she copied the expression incorrectly from the board. If her reasoning and answer for the expression she copied are correct, what expression might she have written?

Answer:

a. Micah is correct

$Expression = 63000 \div 700$

$Expression = 630000 \div 7000$

Step-by-step explanation:

Given

$Expression = 630000 \div 700$

$Desiree = 9000$

$Micah = 900$

Solving (a): Who is correct?

To do this, we first calculate the quotient of the expression.

$Expression = 630000 \div 700$

Divide 630000 by 700

$Quotient = 900$

Hence:

Micah is correct

Solving (b): What Delilah must have copied?

We have:

$Delilah = 90$

There are no options to pick from. So, we just need to work out expressions that equals 0.

Possible expressions are:

$Expression = 63000 \div 700$

$Expression = 630000 \div 7000$

A cube is partially filled to the top with 4 mm3 of water. If the water is 1 mm high, what is the length of one side of the cube

iris [78.8K]

Your answer would be 2 mm. The formula for volume is v=lwh

You have the volume: 4mm. And you have the height: 1. Substituting the known values you have 4=(1)(x)(x).

Now the question is, 1 times what 2 numbers gives you 4? Well 2 does.

4=(1)(2)(2)

The rest of the numbers don't work. 1 times 1 times 1 is 1. 1 times 3 times 3 is 9. And one times 4 times 4 is 16.
