Answer:
Step-by-step explanation:
x =(-7+√-7)/-2=(7-i√ 7 )/2= 3.5000+1.3229i
or:
x =(-7-√-7)/-2=(7+i√ 7 )/2= 3.5000-1.3229i
Answer:
20 % of the original price
Step-by-step explanation:
1). 50 - 40 = 10 $
2). 10 / 50 = 20 %
Given:
monthly budget = 155.60
cost of movies = x
cost of video games = 2.5x
movies + vidgames < budget
x + 2.5x < 155.60
3.5x < 155.60 *expression of inequality
3.5x < 155.60
<u>÷3.5 ÷3.5</u>
x < 44.46
Travis should spend less than 44.46 on movies.
Assuming movie cost 44.
x + 2.5x < 155.60
44 + 2.5(44) < 155.60
44 + 110 < 155.60
154 < 155.60
The answer is 283 1/3 pi because you have to find the volumes of each and then divide the hemisphere by 2 because its only half of a sphere and then add them together
