Some triangles can have a right angle, but not all triangles are right angles. If a triangle has a right angle, it has one angle of 90°. Triangles have a total of 180°.
Hope this helps! :)
60 tables total. 25% of those seat 22 people. 60 X 25% = 15. So 15 of the tables seat 22 people.
The remaining tables (60 tables - 15 tables = 45 tables) seat 44 people.
So you have:
(15 tables X 22 seats) + (45 tables X 44 seats) = total seats.
2310 TOTAL seats.
If we take the number of Zebras to be x and that of peacocks to be y
Then x + y = 14
A zebra has 4 legs while a peacock has 2 legs,
Therefore the total number of legs will be 4x + 2y which is equal to 36 .
Therefore, we have two equations
x + y = 14
4x + 2y = 36 solving them simultaneously using elimination
4x +2y = 36
2x + 2y = 28 ( multiplying the first equation by 2 to eliminate y)
2x = 8 ( subtracting the equations)
x = 4
y = 14 -(4)
= 10
Therefore, there are 4 zebras and 10 peacocks in the zoo
Answer: A. The study compares two or more treatments (possibly including "no treatment").
C. The study involves one or more treatment groups and a control group.
Step-by-step explanation:
The slope of this line can be described as D. zero slope because there is no upward movement, so there is no slope, so it is zero.
Answer: D. zero slope
