<span>In general, if you want x y ths of a number, you multiply it by xy . Let's seek the answer to your question step by step: One tenth of 400 is 110×400=40 1 10 × 400 =40 . One quarter of one tenth of 400 is 14×40 1 4 × 40 , since we found in step 1 thatone tenth of 400 is 40 , and this is equal to 10 .</span>plx mark brainlist
Answer:
the 2nd week is 2 miles longer than the first
Answer:
a =
and b =
Step-by-step explanation:
As we know, the radius of the unit circle is 1 unit (it is the hypotenuse in the right triangle, the blue line)
We use trigonometric formulas to find out a and b
- Sin(45) = opposite side / hypotenuse
<=> Sin(45) = b / 1
<=> b= Sin(45)*1 =
- Cos(45) = adjacent side / hypotenuse
<=> Cos(45) = a / 1
<=> a = Cos(45)*1 = ![\frac{1}{\sqrt{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Csqrt%7B2%7D%20%7D)
So: a =
and b =
Answer:
n = 35
Step-by-step explanation:
n - 13 x -2 = -44
distribute:
(n x -2) - (13 x -2) = -44
-2n - (-26) = -44
two negatives in front of a number makes it a positive number
so rewrite -2n + 26 = -44
-2n = -44 -26
-2n = -70
n = ![\frac{-70}{-2}](https://tex.z-dn.net/?f=%5Cfrac%7B-70%7D%7B-2%7D)
n = 35
calc check (35 - 13) x -2 = 22 x (-2) = -44

Step-by-step explanation:
0.34/ 0.14
0.621/ 0.512
0.536/ 0.612
0.64 - 0.12
0.12 - 0.36
0.59 - 0.25
0.5123 x 0.51232
0.593920 x 0.0591923
