Yo sup??

The given expression is in the form

sinAcosB+cosAsinB

we know that

sin(A+B)=sinAcosB+cosAsinB

therefore

sin40cos20+cos40sin20=sin(40+20)

=sin60

=√3/2

Hope this helps.

Course Grade You were 6 points shy of a B in yo
Oksanka [162]

The point total possible for the given course is equal to 500.

What is a Percent?

  • A ratio whose second term is 100 is known as a percent.
  • Parts per hundred are used in percentages.
  • The mathematical representation of percent is %.
  • The percent formula is given as, x=p \times b, where b is the base number, x is the number being compared to b, and p is the percent in decimal form.

In the question, it is given that you were 6 points shy of a B and the current total points you have is 394.

So, the total number of points you require for a B is calculated as,

394+6=400

So, the value of x is 400.

It is given that you need 80% of the course total for a B.

\implies p=\frac{80}{100}\\ \implies p=0.8

Here, we have to find the base number (b).

We have, x = 80% of b

\implies x=0.8 \times b\\\implies 400= 0.8 \times b\\\implies x=\frac{400}{0.8}

Simplifying, we get

x=500

Therefore, 500 points were possible in the course.

5. A baker had 2 pans of corn bread. He served 1 1/4 pans. What fraction of a pan was left?
Ugo [173]

Answer:

3/4 a pan

Step-by-step explanation:

2 - 1 1/4 = 3/4

two seperated into fourths would look like this

1/4 1/4 1/4 1/4

1/4 1/4 1/4 1/4

one seperated into fourths would look like this

1/4 1/4 1/4 1/4

so take one and one extra fourth away from two and you're left with

1/4 1/4 1/4

add that together and you have 3/4
