Answer:
The answer is 
Step-by-step explanation:
The triangle isosceles has two equal angles and two equal sides
The triangle ABC is an isosceles triangle -----> see the attached figure
-----> radius of the circle
------> angles of the base of the isosceles triangle ABC
------> by central angle ( vertex angle of the isosceles triangle ABC)
Remember that
the sum of the internal angles of a triangle is equal to 
so
Given:
Roses: 22
Daisies: 12
Carnation: 16
22 + 12 + 16 = 50 flowers in one bouquet
The ratio of the roses to the total number of flowers in the bouquet is 22/50 or simplified to 11/25
Ratio of daisies to carnations is 12:16 or 3:4.
Number of carnations to add to make the ratio into 1:3
12:x = 1:3
12*3 = x
36 = x
36 - 16 = 20 additional carnations.
There must be an additional 20 carnations to make the ratio of daisies to carnation 1:3.
12:36 = 1:3
Answer:
There are 40 total questions on his text.
Step-by-step explanation:
To find this, divide the number of questions he got right by the percentage of the total they represent.
32/80% = 40
