The answer is 525
2/3 of residential = 350 customers. so you divide 350 by 2. Which is 175. 175•3= 525
Answer:
<h2>a. The system of linear inequalities is
and
.</h2><h2>b. The solution is given in the figure.</h2><h2>c. The given scenario can happen.</h2>
Step-by-step explanation:
Let, I will buy x pounds Blueberries and y pounds Strawberries.
I need to collect at least 3 pounds of fruits.
Hence, .
It also given that I can not spend more than $21, that is .
If I will buy 4 pound Blueberries and 1 pound Strawberry, then x = 4 and y = 1.
Now, 4 + 1 = 5 > 3. First inequality is satisfied.
, Second inequality is also satisfied.
Given that the plane is at altitude of 1200m and the angle of depression is 28°, to calculate the distance between the the plane and the rock we assume that we a have right triangle whereby the distance of the plane form the ground is the height, the distance from plane to the rock is the hypotenuse and the remaining distance is the base:
thus
sin θ=opposite/hypotenuse
θ=28°
opposite=1200m
hypotenuse=h
thus
sin 28=1200/h
h=1200/sin 28
h=2556.065 m
