Everett made 3/5 of the baskets he shot. Suppose he shot 60 baskets. How many did he make?

Answers

It's a proportion problem 1. Write 3/5 and x/60 (x means you don't know it) 2. Find the number that is multiply to get the product (which is 12) 3. Multiply it (top x top and bottom x bottom) 4. Answer is 36 baskets

Final answer:

Everett made 3/5 of his shots which is 36 made baskets out of 60 shots. We calculated this by multiplying 3/5 (the fraction of shots he made) by 60 (total number of shots) and simplified it to whole numbers.

Explanation:

The subject matter of this question is fraction multiplication, a fundamental topic in mathematics. To find out how many baskets Everett made, we must use multiplication of fractions and whole numbers. Since Everett made 3/5 of his shots and he shot 60 baskets, we need to multiply these two numbers together.

You would do this calculation: 3/5 * 60. Here's a step-by-step breakdown:

Temporarily ignore the denominator (5) and multiply the numerator (3) by 60. That's 180.
Then, divide this number by the denominator: 180 divided by 5. The result is 36.

Therefore, Everett made 36 baskets out of 60 shots.

3 sinx + 4 cosx = 5

Answers

3sinx+4cosx=5
=> 3/5 sinx +4/5 cosx = 1
let cosA=3/5 => sinA=4/5
=> cosAsinx + sinAcosx = 1
=> sin(x+A) = 1
Now,
4sinx - 3cosx
= 5(4/5sinx - 3/5 cosx) [multipying numerator and denominator by 5]
= 5(sinAsinx - cosAcosx)
= -5{cos(x+A)} = -5[root{1-(sin(x+A)^2)}] = -5 x 0 = 0 Ans 0

TRICK: if asinx+bcosx is given then multiply numerator and denominator by root(a^2 +b^2)
this method is useful in many questions
