A 6-pack of beaded necklaces costs $12.78. What is the unit price?

Answers

$12.78/6= $2.13 you take the over all price and divide it by the number of units! brainliest is always appreciated. :)

The unit price for 1 pack of beaded necklaces is $2.13.

What is unit price?

The unit price refers to the price per unit of measures, such as price per pound, quart, ounce, or other units of weight or volume of the food package.

Given that a 6-pack of beaded necklaces costs $12.78.

We need to find the unit price, for the same.

So the unit price will be calculated by dividing the total cost by number of packets,

= 12.78/6 = 2.13

Hence the unit price for 1 pack of beaded necklaces is $2.13.

If the population of an ant hill doubles every 10 days and there are currently 100 ants living in the ant hill, what will the ant hill population be in 20 days?

Answers

Answer:

400

Step-by-step explanation:

The current number is 100, it doubles every ten days, and you're asking what the size will be in twenty days.

Beginning:

100 ants (ten days pass)

100 x 2 = 200

Middle:

10 of the 20 days have passed

Your new number is 200 ants

End:

200 ants (ten days pass)

Since every ten days the size doubles: 200 x 2 = 400

400 ants after 20 days

there would be 400 ants in the hill

During a period of extreme cold, the average daily temperature dropped decreased by 112°F day. How many days did it take for the temperature to decrease by 9°F? Which equation would you use to find the solution?

A x + 112 = 9x + 112 = 9

B x − 112 =−9x − 112 =−9

C −112x = −9−112x = −9

D 112x = 9

Answers

It takes about 4 days for the temperature to decrease by 9°F.

An equation is an expression that shows the relationship between two or more variables or numbers.

Let x represent the number of days. Given that the temperature drop decreased by 1 1/2°F each day (- 1 1/2), for it to decrease by 9°F (-9):

-1 1/2 * x = -9

-1.5x = - 9

x = 4 days

It takes about 4 days for the temperature to decrease by 9°F.

1. 270

2. 277

Step-by-step explanation:

I'm not too sure which answer you're looking for but I'll try to answer all of them :).

First of all, we can consider them in percentage form first.

If the first sale price is marked down by 30%, it is now 70%.

For the second, the price is marked down by 20% first, so 80%.

And then another 10% on top of the 80%. 10% of 80 is 8, so the second one is marked down 80-8, or 72%.

As we can clearly see, 72% is greater than 70% so the first deal( 30% off ) would give you a cheaper price

Now we move on to the actual prices.

First one is 70% of the original price, 70% of $385 is $269.5.

Second one is 72% of original price, 72% of $385 is $277.2

Don't forget to round to the nearest dollar!

Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?

Answers

112.5 seconds

First convert minutes to seconds so 7 x 60 + 30, that will get you the total seconds and should equal 450 secs. Divide that by 4: 450 / 4, equals 112.5 seconds

Answer:

112.5 seconds

Step-by-step explanation:

Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?

You need to do convert 7 minutes in to seconds because you cannot do anything to this unless you convert it.

Remember

1 minute = 60 seconds.

So do 7 times 60.

7 × 60

Which is 420 seconds.

Now add the 30 seconds to that.

420 + 30.

Which is 450 seconds.

Now divided 450 by 4.

450 ÷ 4.

Which is 112.5 seconds per lap.
