We know that
<span>the rotation of a solid does not modify the values of the internal angles of the solid
</span>therefore
interior angle after 90° rotation=interior angle before 90° rotation
interior angle after 90° rotation=108°
the answer is the option D 108 °
Answer:
D, 150 Seniors out of 250
Step-by-step explanation:
Multiply 3*150, and 5*150.
150 over 250 is the same as 3 out of 5.
<span>If there has to be 2 men and 2 women, we know
that we must take a group of 2 men out of the group of 15 men and a group of 2
women out of the group of 20 women. Therefore, we have:
(15 choose 2) x (20 choose 2)
(15 choose 2) = 105
(20 choose 2) = 190
190*105 = 19950
Therefore, there are 19950 ways to have a group of 4 with 2 men and 2women.</span>
<span>If there has to be 1 man and 3 women, we know
that we must take a group of 1 man out of the group of 15 men and a group of 3
women out of the group of 20 women. Therefore, we have:
(15 choose 1) x (20 choose 3)
(15 choose 1) = 15
(20 choose 3) = 1140
15*1140 = 17100
Therefore, there are 17100 ways to have a group of 4 with 3 women and 1 man.</span>
<span>We now find the total outcomes of having a group
with 4 women.
We know this is the same as saying (20 choose 4) = 4845</span>
Therefore, there are 4845 ways to have a group of
4 with 4 women.
We now add the outcomes of 2 women, 3 women, and
4 women and get the total ways that a committee can have at least 2 women.
19950 + 17100 + 4845 = 41895 ways that there will
be at least 2 women in the committee
Answer:
80
Step-by-step explanation:
ramans ratio is 2:3
so in 150ml there are 2 parts of juice and 3 parts of water
2x + 3x = 150
x = 30
so, juice in 150 ml of raman's mixture = 2x = 2* 30 = 60ml
meera ratio is 1:4
similarly,
1y + 4y = 100
y = 20
so, juice in 100 ml of meera's mixture is y = 20ml
so, quanitity of juice in final mixture is 60 + 20 = 80
