In order to answer this, first convert every percentage into decimal value.
The decimal value of 32% is 0.32. We just move two decimal places to the left.
Next move is to multiply the converted percent to the whole or total.
So,
= 0.32 * 35
= 11.2
Take note, there are no decimal pages. So the final answer is 11.
There are 11 pages.
Substitute 51/5x into
Substitute that into
Hope this helps. Answer should be correct. Unless your quadratic equation is wrongly stated.
Answer: Question not very clear
Step-by-step explanation:
I will like to see the original question, then I will attempt to help you. Surely.
Given: sin theta = 2/5. This tells us that the lengths of the opp side and the hyp are 2 and 5 respectively. The adj side is found using the Pyth. Thm.: 5^2-2^2= 25-4 = 21, so that the adj side is sqrt(21).
The double angle formula for the sine is sin 2theta = 2 sin theta *cos theta.
In this particular problem, the sine of 2theta is 2*(2/5)*[sqrt(21) / 5], or:
(4/25)*sqrt(21).
