Answer:
first option
Step-by-step explanation:
divide each side by 'wh' to get:
l = V/wh
Answer:
12
Step-by-step explanation:
49 - 37 = 12
or
It takes 12 jumps to get from 37 (a) to 49 (c)
Answer:
<h2><u><em>
5</em></u></h2>
Step-by-step explanation:
X * 3^2 +2 = 47
X * 9 + 2 = 47
9X = 47 - 2
9x = 45
x = 45 : 9
X = 5
Answer: 130.8 degrees
Explanation:
The problem can be solved by using the cosine theorem:
(1)
where
a,b,c are the lengths of the three sides of the triangle
is the angle between b and c
In this problem, we can identify a,b,c, with:
a = XZ = 11.05
b = XY = 6.32
c = YZ = 5.83
So, the angle corresponds to the angle m∠Y. Re-arranging eq.(1), we find
So, the angle is
Answer:
The numbers are 42 and 49
Step-by-step explanation:
Let's make it into a simple equation. Make the ratios into a single variable like this: 6x+7x=91. If you simplify it more you would get 13x=91. From here divide both sides by 13. This will result with x being 7. But the problem wants you to find 6x and 7x. If you multiply 7 with 6 you would have an answer of 42. If you multiply 7 with 7 you get 49. If you want to check add 42 and 49. If you get 91, this means that the answer is correct
