1/8 Divided by 4 =

Answers

Answer 1
Answer: \sf(1)/(8)/4

Find the reciprocal of 4 and multiply.

\sf(1)/(8)*(1)/(4)

Multiply the numerators and denominators together:

\boxed{\sf(1)/(32)}
Answer 2
Answer: -1/8/-5/4=the numerator of the first value will be multiplied by the denominator of the second i.e 1*4 and similarly 8 will be multiplied by 5like this -1/8 * -4/5this will give 1/10 or 0.1 which is actually the right answe

Jonathas wants to get a cell phone. The phone costs $59 and the plan costs $39 per month. Which expression represents the total cost of a cell phone after m months? 39m
59m
59 + 39m
39 + 59m

Answers

$59 is the fixed cost of the phone and that will never change. This means it won't have a variable attached and will simply be added on to the cost

$39 is how much Jonathans will pay per month. This will change based on how many months pass. This will have the variable attached.

This means the formula is:

59 + 39m

Three rational numbers between 1/4 and 1/5

Answers

Rational numbers are written as a fraction

Between 1/5 and a 1/4 is  same as between   16/80 and  20/80

So 3 rationals between these could be    17/80 ,  18/80 and 19/80

= 17/80, 9/40 and 19/80  (answer)

Write the absolute value equations in the form x−b =c (where b is a number and c can be either number or an expression) that have the following solution sets: Two solutions: x=−2, x=−32.

Answers

Answer:

  |x +17| = 15

Step-by-step explanation:

The absolute value equation ...

  |x -b| = c

can be rewritten as two equations:

  x -b = -c

  x -b = c

The solution to the first is x = b -c.

The solution to the second is x = b +c.

__

The first solution is the smaller of the two, so we have ...

  b -c = -32

  b +c = -2

Adding these two equations gives ...

  2b = -34   ⇒   b = -17

Subtracting the first equation from the second gives ...

  2c = 30   ⇒   c = 15

The the equation you seek is ...

  |x +17| = 15

10 coins have a mass of 45 grams. How many grams is one coin?

Answers

We can't tell from the information given.  We don't know how many
different types of coins there are.  All we know is that all 10 of them
on the scale at the same time have 45 grams of mass.

IF all the coins happen to be identical ... AND each one is worn down
the same amount, AND each one has the same amount of dirt and oil
on it ... then each one has (45/10) = 4.5 grams of mass. 

But those are some big IFs.
45 / 10 = 4.5

There are 4.5 grams in each coin.

Darcy, Jason and Maria share.$268. Jason has $20more than Darcy and Maria has twice as much money as Jason. How much money do Darcy and Jason have altogether?

Answers

x-Jason's\ money\nx-20-Darcy's\ money\n2x-Maria's\ money\n\nx+x-20+2x=268\nx+x+2x=268+20\n4x=288\ \ \ \ \ \ \ |:4\nx=72\n\n72-20=52\n\n72+52=124\n\nDarcy\ and\ Jason\ has\ \$124\ alltogether

Answer:

$124.

Jason- 20$ more than Darcy

Maria- Twice as much as Jason

Darcy- 20$ less than half of Maria's sum.

Step-by-step explanation:

After I had written the page below, I came back up here and realized there was a much easier way.

268/2 = 134

Since the 20 Is added after, half is subtracted and you end up with

124!!

Now for my explanation done first, typed and read as I figured it out.

First and mostly, we need to find what Darcy starts with.

Let's say that Darcy has 5 dollars, to start somewhere easy. That would mean that Jason has 25 dollars since he has 20 more than her. That would mean that Maria would have 50 dollars, and the looted sum is 80.

Since that is less than a quarter of our end goal of 268$, I raised Darcy's initial amount of money to 15 to triple her money.

Math revised here- 15+20= (35*2) 70= 120

15+35+70

Since that is too low, I'm adding it to 30$.

Math revised again here- 30+20=(50*2)=100= 180

30+50+100

  5      15      30

 80    120    180

That is a chart determining our answers so far. There is no clear pattern, so let us continue.

Darcy starts with 50 dollars for this one.

50+20=(70*2)=140

50+70+140

260.

We are close to the sum.

Darcy starts with $52

52+20(72*2)= 144

52+72+144

268!

This means we have found how much Darcy has, and since Jason's amount depends on her, we have found both of their sums!
