Answer:

Cherry Pink has not been made (25:17\neq 4:3)

Step-by-step explanation:

Given that she already has 60litres of Rose Pink paint, we use the ratios to determine the volumes of red/white used:

Rose Pink=60l\\\\Red=\frac{1}{3}\times 60\\\\=20l\\\\White=\frac{2}{3}\times 60\\\\=40l

#Add these proportions to the additional red and white paints to determine if Cherry Pink has been made:

V_r=20l+80l\\\\=100l\\\\V_w=40l+28l\\\\=68l\\\\\therefore r:w=100l:68l     \ \ \ \ \  \ \ \ \  \ \# simplify\\\\r:w=25:17

We equate this proportion to the Cherry Pink proportion to verify if Cherry pink has been made:

25:17\neq 4:3

Hence, Cherry pink has not been made.

Henry takes a math test that had 20 questions.
dezoksy [38]

The percentage of correct answers is 85% and the percentage of incorrect answers is 15% and this can be determined by using the unitary method.

Given :

  • Henry takes a math test that had 20 questions.
  • He answered 17 questions correctly and 3 questions incorrectly.

The following steps can be used in order to determine the percentage of correct and incorrect questions Henry answered:

Step 1 - The unitary method can be used in order to determine the percentage of correct and incorrect questions Henry answered.

Step 2 - The total number of questions in a math test is 20. The total number of correct answers is 17 and the total number of incorrect answers is 3.

Step 3 - If the 20 is the 100% questions then the percentage of 17 correct answers is:

=\dfrac{17}{20}\times 100

= 85%

Step 4 - If the 20 is the 100% questions then the percentage of 3 incorrect answers is:

=\dfrac{3}{20}\times 100

= 15%

Simplify by using the distributive property 3-2(2x+2)-(4x+2)
OleMash [197]

3-2(2x+2)-(4x+2)

Pretend that there is a -1 in front of the second bracket

3-2(2x+2)-1(4x+2)

Multiply the first bracket by 2

Multiply the second bracket by -1

(-2)(2x)(-2)(2)=-4x-4

(-1)(4x)(-1)(2)= -4x-2

3-4x-4-4x-2

-4x-4x+3-4-2

Do 3-4-2 first

3-4-2

-1-2

=-3

-4x-4x-3

-8x-3

Answer: -8x-3
