Answer:
75 students
Step-by-step explanation:
first write a ratio of the students asked to students dislike
40:30, 40 to 30, or 40/30
now simplify the ratio
4/3
now she asked 40 students, so we have to find out the unit rate
so we have to flip the fraction to 3/4 and then divided the top and bottom by 4
0.75/1
now multiply the top and bottom by 100
75/100
75 students
As Tina only has 1/4 of a cake. For simplicity sake we can do the calculation with a whole cake and then multiply by four!
First it is stated that cake is divided into six pieces, giving us our first number.
So,
6 x 4 = 24
This means that each friend will get 1/24th of the whole cake.
ANSWER
EXPLANATION
We use the sine rule for solving triangles.
This is given by the formula,
From the triangle,
We multiply both sides of the equation by 60 to get,
We solve for x to obtain,
To the nearest tenth, we round to one decimal place to get,
Since the triangle has equal sides it will carry onto it self at 120, since it can rotate 360 grades only and it has 3 sides so it will rotate in one third of 360 so 120
