Answer:
B, C, A, B
Step-by-step explanation:
i. 60+ 10 +110 = 180 ( so it can be scalene)
ii. 60 +120 =180 ( they have to, to make a triangle)
iii. Obtuse is 90 degrees or more
iv. 90 +60+30=180 (so it can be)
Answer:
2 people ordered salah
Step-by-step explanation:
#Total number of people in the class = 40
#Number of people who ordered chicken= 1/5 of the total number of people;
that is, ⅕×40=8
therefore 8 people ordered chicken.
#Number of people who ordered hamburgers= ¾of the total number of people.
that is; ¾×40=30
therefore 30 people ordered hamburgers.
#Number of people who ordered salad= total number of people - the sum of people who ordered chicken and hamburgers.
that is,
40 - ( 30 + 8 ),.
40 - 38 = 2
Answer:
x ≈ -7.73 , - 4.27
Step-by-step explanation:
x² + 12x + 33 = 0 ( subtract 33 from both sides )
x² + 12x = - 33
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = - 33 + 36
(x + 6)² = 3 ← take square root of both sides )
x + 6 = ± ( subtract 6 from both sides )
x = - 6 ±
Then
x = - 6 - ≈ - 7.73 ( to the nearest hundredth )
x = - 6 + ≈ - 4.27 ( to the nearest hundredth )

Answer:
Step-by-step explanation:
Given
On first day bag contained 1 kernels
on second bag contained 2 kernels of corn
on third day bag contained 4 kernels of corn
on n th day bag contains kernels of corn
thus on 26 th day bag contains kernel
Each kernel weigh 0.07 gm
Therefore kernels weighs
Therefore on 26 th day kernel weighs 23,488.1024 kg
