Set up a proportion.
8/127=15/x
Cross multiply
8x=1,905
Divide both sides by 8
x=238.125
The longest of the real-life distances is 238.125 km.
Hope this helps :)
Because v1 x v2 + v2 x (-v1) = v1 x v2 - v2 x v1 = v1 x v2 - v1 x v2 = 0, vector (v1,v2) is orthogonal to (v2,-v1);
Let (a,b) be an unit vector orthogonal to (9,40);
So, a^2 + b^2 = 1 and a x 9 + b x 40 = 0;
Then, a = - 40 x b / 9;
Finally, 160 x b^2 / 81 + b^2 = 1;
160 x b^2 + 81 x b^2 = 81;
241 x b^2 = 81;
b^2 = 81 / 241;
b = + or - 9/

a = + or - 40/

We have (+40/

;9/

) and (-40/

;-9/

);
The unknown value there is 1500.
It is increasing by 250
Answer:
$3.74
Step-by-step explanation:
we already know the cost of the banana's and it gives us the total price including apples. So $5.24 - $1.50 = $3.74, and the 3.74 is the cost of apples
