42•0.15=6.3
42-6.3=35.7

That's how you calculate percents :)

First, you multiply 42 by .15 which you get $6.30
Then, you subtract $42 by $6.30 which you get the answer: $35.70

If three pies require 2 dozen apples, then four bird require ? dozen apples?

Nata [24]

Answer is 2-2/3 dozen apples, or 2.66 dozen as a repeating fraction.
Step by step
we know 2 dozen apples is 24 apples
We know 24 apples per 3 pies
To get the rate per pie, divide 24 apples per 3 pies
24/3 = 8 apples per pie
Now multiply 8 apples x 4 pies = 32 apples
Now we need to answer in how many dozen apples. Divide 32 by 12 (1 dozen)
Answer is 2.66 dozen apples or 2-2/3 dozen apples

(NEED DONE QUICK) Two angles are supplementary. One of the angles measures 4(2x+9) and the other angle measures 2(4x-8) what is

Studentka2010 [4]

Answer:

$x=10$

Step-by-step explanation:

Supplementary angles are angles equal to 180°.

Therefore:

$4(2x+9)+2(4x-8)=180$

Now that we have our equation, let's distribute the $4$ and the $2$ into the parentheses they are next to:

$8x+36+8x-16=180$

Combine like terms:

$16x+20=180$

Subtract $20$ from both sides of the equation:

$16x=160$

Divide by the coefficient of $x$ , which is $16$ :

$x=10$

~

Check your work by substituting $10$ into one of the equations above:

$8(10)+36+8(10)-16=180$

$80+36+80-16=180$

$180=180$

It's correct!

A maritime flag is shown. What is the area of the shaded part of the flag? Explain

Rom4ik [11]

Answer:

<em></em> $Area = 72in^2$ <em></em>

<em></em>

Step-by-step explanation:

<em>Your question is incomplete without an attachment (See attachment)</em>

Required

Determine the area of the shaded part

From the attachment;

<em>Assume that the shaded portion is closed to the right;</em>

<em>Calculate the Area:</em>

<em></em> $Area_1 = Length * Width$ <em></em>

<em></em> $Area_2 = 8in * (6in + 6in)$ <em></em>

<em></em> $Area_2 = 8in * 12in$ <em></em>

<em></em> $Area_1 = 96in^2$ <em></em>

<em></em>

<em>Next;</em>

<em>Calculate the Area of the imaginary triangle (on the right)</em>

<em></em> $Area_2 = \frac{1}{2} * base * height$ <em></em>

<em></em> $Area_2 = \frac{1}{2} * (6in + 6in) * 4in$ <em></em>

<em></em> $Area_2 = \frac{1}{2} * 12in * 4in$ <em></em>

<em></em> $Area_2 = \frac{1}{2} * 48in^2$ <em></em>

<em></em> $Area_2 = 24in^2$ <em></em>

<em></em>

<em>Lastly, calculate the Area of the Shaded Part</em>

<em></em> $Area = Area_1 - Area_2$ <em></em>

<em></em> $Area = 96in^2 - 24in^2$ <em></em>

<em></em> $Area = 72in^2$ <em></em>

<em></em>

<em>Hence,</em>

<em>The area of the shaded part is 72in²</em>
