How do you put 27% ,miles per hour , 42% and 45 in a sentence
Serjik [45]
  There are a number of possible combinations for this open-ended question, so here's an example question and answer, in which the two are non-related:
 James' car is going at 45 miles per hour, and that is 42% of his maximum speed. How much slower does James have to go to be 27% of his maximum speed?
 Amy's car used to be able to go at 45 miles per hour as 42% of her maximum speed, but due to the new upgrade, 45 miles per hour is now only 27% of her maximum speed.

Find the exact value:<br> tan40/cot50<br><br> sec55/csc35<br><br> SHOW ALL WORK!
serious [3.7K]
These are the important trigonometric relations to base on:

cot (x) = 1/tan(x)
sec(x) = 1/cos(x)
csc(x) = 1/sin(x)

Following these properties, we could simplify the equation and input into the calculator to determine the exact value.

<span>tan40/cot50 = tan40/(1/tan50) = tan40tan50 = 1

</span><span>sec55/csc35 = (1/cos 55)/(1/sin 35) = sin35/cos55 = 1</span>

a boat salesperson earns a 2.5% commission on the sale of each boat Find the commision earned on a boat that sells for 18,500
marin [14]
100% = 1.0
2.5% = 0.025

So now we know the decimal that corresponds to 2.5%, so all we have to do is multiply the price of the boat by this value in order to find the commission earned:

18 500 x 0.025 = $462.50
