Lisa and Bill made 60 magnets for a craft fair. They sold about 55% of the magnets. Lisa says they sold about 30 magnets. Bill s
koban [17]

Answer:

Step-by-step explanation:

The total number of magnets that Lisa and Bill made for the craft fair is 60.

They sold about 55% of the magnets. The number of magnets that they sold would be about

55/100 × 60 = 0.55 × 60 = 33

If Lisa says that they sold about 30 magnets, she is correct because if we round off 33 to the nearest ten, it would be 30 magnets.

If Bill says that they sold about 36 magnets, he is wrong because if we round off 36 to the nearest ten, it would be 40 magnets.

Answer:

y = 1500(0.024)^t

Step-by-step explanation:

Given

a = 1500km -- initial area

b = 2.4\% -- rate

t = time --- (years)

Required

Represent as an exponential function

An exponential function has the form:

y = ab^t

Where

a = initial\ value

b = rate and b \ne 1

t= time

Substitute values for a and b, we have:

y = 1500 * (2.4\%)^t

Convert percentage to decimal

y = 1500 * (0.024)^t

y = 1500(0.024)^t

Hence, the exponential function that represents the scenario is: y = 1500(0.024)^t

180:60 in its simplest from
kipiarov [429]

Answer:

3:1

You can easily figure out that 60 is a factor of 180 bc 6 is a factor of 18.

So you can simplify it to 18:6

Then divide both sides by 6 and you will get 3:1

Hope this helps ;)
