Answer:
p = -0.05x+22
Step-by-step explanation:
The general linear equation of price-demand is
(1) <em>p = mx + b
</em>
<em>
</em>
where x is the demand of cards in units when they are sold at x dollars.
If for every additional card they wish to sell they need to drop the price by $0.05, then
(2) p-0.05 = m(x+1)+b
To sell 360 cards they need to set the price at $4, so
(3) 4 = m.360+b
We need to find m and b.
Operating on eq. (2) we have
p-0.05 = mx+m+b
mx+b-0.05 = mx+m+b
m = -0.05
Replacing this value in (3)
4 = (-0.05)360 +b
4 = -18+b
b = 22
So, the linear equation relating price p to demand x is
p = -0.05x+22

Answer:
The angle between the two sides of the right triangle is aproximately 31.003º.
Step-by-step explanation:
From image attached on question we infer that we need to find the angle between sides of lengths 6 (adjacent leg) and 7 (hypotenuse) in the right triangle. The angle can be found by means of this trigonometric ratio:



The angle between the two sides of the right triangle is aproximately 31.003º.
Answer:
It would be {10, 16, 27}, {12, 27, 39}, {8, 22, 31} that DO NOT represent 3 sides of a triangle
Step-by-step explanation:
Since the only answer where the first 2 numbers is greater than the 3rd/last number is {14, 28, 39} (which makes it the only traingle), the others would ALL NOT be triangles.
Answer:
256
Step-by-step explanation:
so the basic problem is 192 divided by 3/4, so you flip the second fraction around. So the problem is now 192*4/3.
SIMPLIFY
192/3 is 64, and then you times 64 to 4, which equals 256
Hope it helped!
