Liam has a bag of b beads. He gives 20 beads to his sister. He then makes 4 necklaces with the same number of beads on each necklace using all of the remaining beads. Write an expression that represents the number of beads on each necklace. Show your work.

Answers

Answer 1
Answer:

The expression in one variable b that shows the number of beads on each necklace is (b-20)/4

What is an expression in one variable?

An expression in one variable is a statement formed by the using constants and an unknown variables and mathematical operators but sign is equal to is not used. Expression in one variable is linear if the power of the unknown variable is equal to one .

Standard form of linear expression in one variable x is  ax +b , where a and b are constants .

Given that Liam has a bag of b beads

He gave 20 beads to his sister

Then, remaining beads = b -20

Remaining beads are used to make 4 necklaces

Let the beads on each necklace be x

Then beads in four necklaces = 4x

As, Remaining beads = beads in four necklaces

⇒4  x = b - 20

Dividing the equation by 4 on both sides

⇒ x = (b-20)/4

∴ The expression that shows the number of beads on each necklace is (b-20)/4

devin began running a month ago to get back in shape.the first day he ran .5 miles. each day after that he ran 10% more than the previous day for a total of 30 days. use the formula for the sum of a finite geometric series to calculate the total distance devin ran over the 30 days.

Answers

The formula for the sum of the a finite geometric series is this:
Sn = a((1-r^n) / (1-r))

The given values are:
n = 30
a = 0.5 mi
r = 1.10 (10% more each day)

S30 = 0.5 ((1-1.10^30) / (1-1.10))
S30 = 82.25 mi

After 30 days, he will have traveled 82.25 miles.

4 is 50% of 8 

If you divide the mass of a substance by its volume, can you can find its density?

Answers

So the question is is it true or false that when you divide the mass of a substance by it's volume you will get its density. So from the definition of density we know that density=mass/volume or: D=m/V. So the answer is true, when you divide a mass of a sbstance by its volume, you get it's density.
