jen uses 8.2 of blue paint and white paint to paint her bedroom walls. 4/5ths of this amount is blue paint, and the rest is whit
lara31 [8.8K]

Answer:

The amount of white paint Jen used to paint the walls in her room is:

  • <u>1.64 pints.</u>

Step-by-step explanation:

To solve the exercise you only have to pay attention to the statement, in the section that says that 4/5 parts of the total painting is blue, therefore, if 1 is the total painting, you must do a subtraction:

  • 1 - 4/5 = 1/5

Since the remaining white paint is 1/5 of the total, you have two ways to solve the exercise: multiply the total paint (8.2 pints) by 1/5 or divide the number by 5, as shown below:

  • <u>Amount of white paint = 8.2 pints * (1/5) = 1.64 pints. </u>
  • <u>Amount of white paint = 8.2 pints / 5 = 1.64 pints. </u>

As you can see, the two methods provide a <u>value of 1.64 pints, which corresponds to 1/5 of the total paint and is the amount of white paint used</u>.

Tpy6a [65]

Answer:

30,240 ways,  if I am restricted to using A, B, and C for letters

Step-by-step explanation:

This uses Combinatorics from Discrete Math.

so.

3 letters  and 4 digits.

26 letters from alphabet, but you want to choose first letters.  no repeats...

Does this mean only letters A, B, and C ?

digits from 10 digits...

I imagine  7 empty slots , and the number of ways they occur together is by the product of the number of choices each box has.

3*2*1  *  10*9*8*7 = 6  * 5040  = 30,240 ways

PLEASE HELP ASAP PYTHAGOREAN THEOREM
kramer

11.66 or 12

Step-by-step explanation:

c^2 = a^2 + b^2

19^2 = 15^2 + b^2

361 = 225 + b^2

361 - 225 = b^2

136 = b^2

(square root of both sides)

b = 11.66or 12
