Since an isosceles triangle has two angles that are the same, and one different, the 120 degrees would be the different one. 180-120= 60 degrees 60/2=30 degrees
The answer would be D, she went from 0 to 20, then lost 10 points which would bring her 10 points, and then she lost an additional 25 points, bringing her to negative 15 (-15)
Cost = 300 x + 750 , where x is the number of the scooters;
Price = 900 - x
Profit = x ( 900 - x ) - ( 300 x + 750 ) =
= 900 x - x² - 300 x - 750 = - x² + 600 x - 750
d (Profit) = - 2 x + 600
- 2 x + 600 = 0
x = 600 : 2
x = 300
The company must produce 300 scooters to maximize the profit.
The maximum profit is:
- 300² + 600 · 300 - 750 = $89,250
Answer:
1) 130°
2) 130°
Step-by-step explanation:
Assuming SR, TU, and PQ are parallel, they would both be 130. (180-50)
Answer:
y=4 mm
Step-by-step explanation:
All angles in a triangle add up to 180: 180=∠M+∠P+∠N, ∠M=180-60-90=30
<u>Use sine rule</u>
a/sinA=b/sinB
PN/sin∠M=PM/sin∠N
y/sin30=8/sin90
y=8/1 *sin30
y=8*0.5
y=4 mm
