Answer:
35triangles
Step-by-step explanation:
Given
Total distinct points = 7
If we are to form triangles using the dots,
Total points in a triangle = 3
Using the combination rule;
number of triangles formed = 7C3
7C3 = 7!/(7-3)!3!
7C3 = 7!/4!3!
7C3 = 7*6*5*4!/4!3!
7C3 = 7*6*5/6
7C3 = 7*5
7C3 = 35
Hence the amount of triangles that can be formed is 35triangles
Answer:
3/10
Step-by-step explanation:
Answer:
log1/8
Step-by-step explanation:
Answer:
Given expression is,
9(x+3) = 108
In solving the equation the steps are as follows,
Step 1 : 9x + 27 = 108 ( By distributive property )
Step 2 : 9x = 81 ( Subtracting 108 on both sides )
Step 3 : x = 9 ( Divide both sides by 9)
Hence, by the above explanation we can drag the steps of solution in correct order.
Answer:
chocolate= 180 students
vanilla= 120
strawberry= 210
mango= 210
Step-by-step explanation:
The chocolate section of the pie chart is at a right angle (90 degrees), which means a quarter of the students prefer chocolate
720/4= 180
The vanilla section is 60 degrees which is 2/3 of 90
180/3=60
60x2=120
the mango and strawberry sections represent whats left which is 420 students. The sections are equal to each other so they're each 210 students
