∠A= 60°
Step-by-step explanation:
Answer:
0.189
4.525
Step-by-step explanation:
v/1 + 2/v + 4v/3 = 11
we can eliminate denominators if we distribute 3v to each term:
3v(v/1 + 2/v + 4v/3) = 3v(11)
3v² + 6 + 4v² = 33v
7v² - 33v + 6 = 0
factor this trinomial:
there are no factors of 6 that would add to -33 so we can use the quadratic formula to solve: (-b ± √b²-4ac) / 2a
a = 7
b = -33
c = 6
[33 ± √(-33)² - 4(7)(6)] / 2(7)
(33 ± √1089 - 168) / 14
(33 ± √921) / 14
(33 ± 30.35) / 14
(33+30.35) / 14 = 4.525
(33-30.35) / 14 = 0.189
Answer: 1/5 a foot taller
Step-by-step explanation: Basically you just subtract 2/5 from 3/5. That gives you 1/5.
Answer:
okay so the lines on the side of the triangle show that sides AB and AC are congruent so angle C would also be 40 degrees. angle A on the other hand would be 90*
Step-by-step explanation:
Answer:
6(10)+5x=180
Step-by-step explanation:
The grocery store received a crate of 180 pound...
So, the whole amount is 180..
The crate contains six 10 pound bag of potato plus an unknown number of 5pound bag of potato....
So if we think, that the unknown number is x the equation would be
6(10)+5x=180
Hope ya find this helpful..
