Answer:
D is the right answer for this question
Answer:
29/100 (Every 100 students, 29 more students like cats than dogs)
Step-by-step explanation:
First we need to put these numbers in fractions
The fraction that represents students that like dogs is 9/25
The fraction that represents students that like cats is 13/20
Now, we just need to subtract the fraction of cats by the fraction of dogs:
13/20 - 9/25
To do that, we need to make the denominators equal. We do that making multiplying the first fraction by 5 and the second by 4, so we have:
13/20 = 65/100
9/25 = 36/100
Then, subtracting then, we have:
65/100 - 36/100 = 29/100
So every 100 students, 29 more students like cats than dogs.
Answer:
m<3 = 80
Step-by-step explanation:
We know that the sum of all the angles in a triangle is 180.
Thus, we can find the m<3 using the equation 180 - (70 + 30) = m<3
Simplifying gives us m<3 = 80
