Since there only 3 colors you add 12/20(Red) + 6/12(Blue) and get 18/20(Combined Red and Blue)

Then you take out the Combined red and blue from the total percentage or 20/20(All 3 Combined/Full spinner)-18/20(Combined red+blue)=2/20

The answer is A.2/20

Bill's chocolate bar is 69% cocoa. If the weight of the chocolate bar is 83 grams, how many grams of cocoa does it contain? Roun
Maurinko [17]

Answer:

Bill's bar has 57.3 grams of cocoa.

Step-by-step explanation:

The math part that your question is asking is: What is 69% of 83?

In order to use the percent 69% in a calculation, you need to change it to a decimal.

69% is 0.69

You move the decimal to the left, two places.

69% is 69.% If you don't see a decimal to start with and it is a whole number, then the decimal is starting on the right.

Move it two places to the left, you get

.69

Now MULTIPLY.

.69 × 83

= 57.27

ROUND your answer to the nearest tenth. That means only one digit to the right of the decimal.

57.27 rounds to 57.3

Bill's bar has 57.3 grams of cocoa.

Temka [501]

Given:

Jason buys three shirts with a listed price of $20 each.

He uses a coupon that provides "Buy Two, Get One Free".

To find:

The total final price Jason pays.

Solution:

Total number of shirts he buys = 3

Since he uses a coupon that provides "Buy Two, Get One Free", therefore he need to pay for 2 shirts and 1 he will get free.

Cost of 1 shirt = $20

Cost of 2 shirts = 2 × $20

                        = $40

Therefore, total final price Jason pays is $40.

Differentiate Functions of Other Bases In Exercise, find the derivative of the function.
Maslowich

Answer:

\frac{dy}{dx}=3x^{3x}(lnx+1)

Step-by-step explanation:

We are given that a function

y=x^{3x}+1

We have to find the derivative of the function

Let u=x^{3x}

y=u+1

Taking ln on both sides

lnu=3xln x

By using lna^b=blna

Differentiate w.r.t x

\frac{1}{u}\frac{du}{dx}=3(lnx+x\times \frac{1}{x})=3(lnx+1)

\frac{d(lnx)}{dx}=\frac{1}{x}

\frac{d(u\cdot v)}{dx}=u'v+v'u

\frac{du}{dx}=3u(lnx+1)=3x^{3x}(lnx+1)

Differentiate  y w.r.t x

\frac{dy}{dx}=\frac{du}{dx}

Using the value of du/dx

\frac{dy}{dx}=3x^{3x}(lnx+1)

45.7 kilometers =<br> meters
VashaNatasha [74]

Answer:

45.7 kilometers = 45,700 meters

Explanation:

Hi!
Okay, so basically, in one kilometer, there are 1000 meters.
Using this problem, all you have to do is <u>multiply 45.7 by 1000</u>, which is 45,700.

Whatever value is used for kilometers (ex. 2), just multiply by 1000, and you’ll get the value as meters (ex. 2 x 1000 = 2000 meters).


Hope this helps!
