<h2>$13 </h2>
Step-by-step explanation:
Step one:
given
amount of pound= 2 1/2 in decimal notation= 2.5 pounds
cost of 2.5 pounds= $32.5
Step two:
Required
we want to find the charge per pound
if 2.5 pounds cost $32.5
1pound will cost x
cross multiply we have
x= 32.5/2.5
x=$13
The cost per pound is $13
Answer:
x=3
Step-by-step explanation:
Secant-Secant Formula:
(whole secant) x (external part) = (whole secant) x (external part)
9*4 = 12*x
36 = 12x
Divide each side by 12
36/12 = 12x/12
3 =x
Answer is 26+15i
(2-7i) x (-1+4i)
-2+2x4i-7i ( -1) -7i+4i
-2+8i+7i-28i^2
-2+8i+7i-28(-1)
-2+8i+7i+28
26+ 15i
Answer:
<em> The distance from your eyes to the stage is 8.85 ft</em>
Step-by-step explanation:
Your distance to the stage is 6 feet
Your eyes are 6.5 feet tall
You need to find the distance of your eyes towards the stage.
This situation can be modeled using a rectangle triangle, where the adjacent side x is the horizontal distance to the stage and the opposite side h is the vertical distance of your eyes to the stage.
<u>Observe the attached image.</u>
Then, we look for the distance z from your eyes to the stage. This distance is the hypotenuse of the right triangle.
So, using the Pythagorean theorem we have:

Where

therefore:
