For this case we must build a quotient that, when multiplied by the divisor, eliminates the terms of the dividend until reaching the remainder.

It must be fulfilled that:

$Dividend = Quotient * Divisor+Remainder$

Looking at the attached image we have to:

Remainder: -1

Quotient: $5x + 5$

Stacy and Neil painted 280 ft2 of their living room wall with 45 gallon of paint. How many square feet can they paint with 3 gal

Alecsey [184]

Answer:

They can paint 18. 66 sq ft with 3 gallons of paint.

Step-by-step explanation:

Total area painted = 280 sq ft

Total gallons of paint used = 45

So, 45 gallons of paint painted 280 sq ft.

⇒ By UNITARY METHOD,

1 gallon of paint paints $(\frac{280}{45} )$ sq ft

So, area painted by 1 gallon = 6.22 sq ft

⇒ area painted by 3 gallon = 6.22 sq ft x 3 = 18. 66 sq ft

So, they can paint 18. 66 sq ft with 3 gallons of paint.

5. Complete the following statement. Write your answer as a decimal or

Finger [1]

Answer:

20% or . 2

Step-by-step explanation:

To understand how to solve, you have to understand that 14 can go into 70 (X) amount of times, this is how percentages work. To find how many times 14 goes into 70, you divide 14/70 = .20

Since 14 is 20% of 70, you can multiply 14 by 5 and it equals a 100% of 70, or just 70 itself. Hope this helped

Answer:

Interquartile range => 7

Third quartile => 22

Range => 13

First quartile => 15

Step-by-step explanation:

Order your data set, from the least amount to the highest amount:

$12, $14, $15, $15, $15, $15, $16, $22, $24, $25

Interquartile range (IQR) = third quartile (Q3) - first quartile (Q1)

Q1 = the middle value of the lower part of the data set, from the median to your left.

Q3 = the middle value of the upper part of the data set, from the median to your right.

The median lies between the 5th and 6th value that is enclosed in the parenthesis below:

$12, $14, ($15), $15, $15,[Median], $15, $16, ($22), $24, $25

The median divides the data set into upper and lower part.

Median = $\frac{15 + 15}{2} = 15$

First quartile: Q1 = $15

Third quartile: Q3 = $22

IQR = $22 - $15 = $7

Range = highest amount - least amount = 25 - 12 = $13
