Since the ratio is 10:3 we can find the total number of children and adults by finding how many times 13 (10+3) goes into 39. 39 / 13 = 3 so we can take the original 10:3 ratio and just scale it up to fit the whole group 10:3 * 3 -> 30:9:

From here it gets a little easier we know three adults of the 30 get off at the next stop bringing us to 27. So now our ratio is 27:9 we can simplify that down to 3:1 to get our final answer. Hope that helps!

Meyer restocks on toilet paper Sunday they get 800 rolls. They are open Monday through Sunday 8am to 10pm. They sell 16 rolls pe
ohaa [14]
Remember 800 because that’s your big number / most important.

So they’re open from 8am - 10pm. They’re open for 14 hours a day and they sell 16 rolls per hour.
If one hour is 16 rolls sold , then what is 14?
16 x 14 hours (16 x 14 = 224)
In a whole day they sell 224 rolls.
Monday: 800 rolls - 224 rolls = 576 rolls
Tuesday: 576 rolls - 224 rolls = 352 rolls
Wednesday: 352 rolls - 224 rolls = 128
By Thursday they won’t be able to sell more than 224 because there is only 128 rolls left that will be sold out in 8 hours on that day.
So they will be sold out completely by THURSDAY.
The best time to go to the store is most likely on a Tuesday around 12-1pm

Explain to me the strategy that you use to order a group of numbers that may be written in different forms, for example percenta
tino4ka555 [31]

Answer:

Convert fractions, decimals, and percents to the same form to compare the values. Convert Percent to Decimal or Fraction. Convert Decimal to Percent or Fraction. Convert Fraction to Decimal or Percent. Then figure out which is greater or lesser. Use this information to write a set of numbers or quantities in order from least to greatest or from greatest to least.

Step-by-step explanation:

Ordering numbers mean plan of numbers either from little to enormous or from huge to little. At the point when the numbers are orchestrated in an expanding order, it is known as Ascending Order, and when the numbers are organized in a diminishing order, and afterward they are known as Descending Order. For ascending, check the most modest number from the given rundown and spot it first and afterward put the numbers as indicated by the expanding order. For descending check the greatest number from the given rundown and spot it first and afterward put the numbers as per the diminishing order.

A percentage is a part of an entire communicated as a number somewhere in the range of 0 and 100 instead of as a portion. All of something is 100 percent, half of it is 50%, none of something is zero percent.

A decimal is a part written in an extraordinary structure. Rather than composing 1/2, for instance, you can communicate the division as the decimal 0.5, where the zero is during the ones spot and the five is in the tenths spot.

A fraction just discloses to us what number of parts of an entire we have. You can perceive a fraction by the slice that is composed between the two numbers. We have a top number, the numerator, and a base number, the denominator. For instance, 1/2 is a fraction. You can compose it with an inclined slice like we have or you can compose the 1 on the 2 with the slice between the two numbers. The 1 is the numerator, and the 2 is the denominator.

Write quadratic equation whose roots are 1 and -3 and whose leading coefficient is 4
Mila [183]

Answer:

4x^2 + 8x - 12 = 0.

Step-by-step explanation:

We first write it in factor form.

4(x - 1)(x + 3) = 0

4(x^2 + 2x - 3) = 0

4x^2 + 8x - 12 = 0 (answer).
