Answer:
3
Step-by-step explanation:
12*0.75=9
To find this do 9/12.
4*0.75=y
y=3

Given:
Two vectors (u) and (w) and the angle between them θ
the sketch of the vectors will be as shown in the following figure:
As shown, the resultant vector is the blue line segment
The vector R has a magnitude = 60.22
And the angle between u and R = 5.56°
Answer:
lol number 8 is x= i, -i , 
, -4 so u are correct.
and number 7 is x=
or ![\sqrt[5-i]\sqr\frac{23}{8}](https://tex.z-dn.net/?f=%5Csqrt%5B5-i%5D%5Csqr%5Cfrac%7B23%7D%7B8%7D)

Answer:
5.714 liters of the 5% solution and 4.286 of the 40%.
Step-by-step explanation:
Let x be the volume of 40% solution and y = volume of the 5% solution.
x + y = 10
0.40x + 0.05y = 0.20(x + y)
From the first equation x = 10 -y so we have:
0.40(10 - y) + 0.05y = 0.20( 10 - y + y)
4 - 0.40y + 0.05y = 2
-0.35y = -2
y = 5.714 liters of the 5%.
and x = 10 - 5.714 = 4.286 liters of the 40% solution.
