14 days = 2 weeks so
14 times 3 = 42
I'll assume that what was meant was
.
The exponent in the funny place is just an abbreviation:
.
I hope that's what you meant. Let me know if I'm wrong.
Let's start from the old saw
Squaring both sides,
So now the original question
becomes
Now we use the sine double angle formula
We square it to see
Taking the square root,
Not sure how you want it; we'll do it in degrees.
When we know the sine of an angle, there's usually two angles on the unit circle that have that sine. They're supplementary angles which add to
. But when the sine is 1 or -1 like it is here, we're looking at
and
, which are essentially their own supplements, slightly less messy.
That means we have two equations:
integer
or
We can combine those for a final answer,
integer
Check. Let's just check one, how about
The answer is 240.
25% =
Instead of multiplying the % with the number, we will be dividing.
Multiply the reciprocal of the % with 60 and that would be your answer.
Answer:
The length of longest side is 25 cm.
Step-by-step explanation:
Given that the perimeter of rectangle is, P = 2(l+w) where l represents length and w is width.
In this question let length be the shorter side and width be the longer side. Given that the length of this rectangle is 10 cm and the perimeter is 70 cm, so you have to substitute it into the formula :
Let p = 70 cm,
Let l = 10 cm,
Let w = w cm,
Answer:
j = 17.32 sq rt 3 or 30
Step-by-step explanation:
sin 60 = j/20sq rt 3
0.8660 = j/20sq rt 3
j = 17.32 sq rt 3
