Answer:
45 degree or 25%
Step-by-step explanation:
sum of angles of triangle= 180 so
-----> angle 1
(note: 30% is equal to 
)
------> angle 2
lets add angle 1 and 2 together
54+81=135
now lets subtract it from 180 to get the remained angle
180-135=45 and if you want it in % so you just get 100%-(30%+45%)= 25%
Answer:
(5x − 4)(x + 2)
Step-by-step explanation:
For the purpose, it is sufficient to make sure the middle terms match.
The middle term in the product of each of the answer choices is ...
-1+40 ≠ 6
-8+5 ≠ 6
-4+10 = 6 . . . . . the third selection is the one you want
-2+20 ≠ 6
The ratio of Red Apples to Green Apples is 5:2. The proportion of red apple is 5/7.
The store sold 45 red apples.
So the combined amount of red and green apples sold = No of red apples sold divided by the proportion of red apples = 45/ (5/7) = 63
The combined amount of red and green apples sold is 63 apples.
Answer:
Those who were able to keep 12 fishes
Step-by-step explanation:
Given
Total = 20 (each)
Required
Which was able to keep 3/5
First, we need to calculate 3/5 of the total number of fishes
Fish = 3/5 * 20
Fish = (3 * 20)/5
Fish = 60/5
Fish = 12
From the calculation above, only those who keep 12 of the 20 fishes were able to keep 3/5 of their fishes
