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

b.

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

It takes Dwight 1 1/3 hours to run the sunshine trail. Mike 3 1/5 hours to walk the same trail. How many times as long does it t
Anit [1.1K]

For this case we convert the mixed numbers to fractions:

Dwight:1 \frac {1} {3} = \frac {3 * 1 + 1} {3} = \frac {4} {3} = 1.33

Mike:3 \frac {1} {5} = \frac {5 * 3 + 1} {5} = \frac {16} {5} = 3.2

It is observed, that in fact, Mike takes more time to travel the road.

We subtract to know how much more time it takes Mike:

\frac {16} {5} - \frac {4} {3} = \frac {48-20} {15} = \frac {28} {15}

So, Mike takes \frac {28} {15} hours more than Dwight to walk the road.

Answer:

Mike takes\frac {28} {15}hours longer than Dwight to walk the road.

Can someone explain positive and negatives to me
Alex777 [14]

(I will do my best to entirely explain the subject) To understand Positives and Negatives you need to have a number line.

<u>-3 -2 -1 0 1 2 3</u>

Your whole life you have been using positives and negatives when you subtract or add a number. 9 - 2 is really just 9 + -2

With the number line it should be easier to understand that for every single time you add or take away you change the value. The more you take away (Negative numbers, 5 + -6) the farther down the value goes to the left, more towards the negative side (5 + -6 = -1). The same goes for addition (-6 + 9 = 3).

To multiply all you need to do is count how many times you see a negative number. If you see an even number of negatives then the answer will be positive because on the number line you went from one side to the other multiple times, left right left right and all that jazz. Hopefully i made this make more sense to you, if there is anything i need to clarify on please make it known so i can edit my answer.
