Let's plug in the variables one by one.
6g - 2h
plug in 5 for g and 4 for h
6(5) - 2(4)
multiply
30 - 8
subtract
→ 22
20g
plug in 2 for g
20(2)
multiply
40
2(g + 1)
plug in 10 for g
2(10 + 1)
add
2(11)
multiply
→ 22
4g + 5h
plug in 1 for g and 4 for h
4(1) + 5(4)
multiply
4 + 20
add
24
Therefore, the answers that have a value of 22 are 6g - 2h and 2(g + 1)
Answer:155in^2
Step-by-step explanation:
Area of the poster board that she has left=Area of ||gm- area of ∆
Area of the poster board that she has left= 10*20-1/2*9*10
Area of the poster board that she has left=200-45=155in^2
Answer:
False
Step-by-step explanation:
We are told that there is a 33% probability that physics students belong to ethnic minorities, therefore if the sample is 10 people, the amount would be given as follows:
10 * 33% = 3.3 people would be from ethnic minorities. What means of those 10 no more than 4 (to round the number) people belong to an ethnic minority.
Therefore, this statement is false, because it does not represent exactly the probability established in the university.
It is possible to clarify that what affirmation is true part because it fulfills what it says, because the probability says that 4 or less, and the affirmation says that 6 or less, however, the affirmation mentions that it corresponds to the probability of 33% and that if it is false, to correspond it should be between 51% and 60%.
Answer:
Step-by-step explanation:
Base, b = 1/3
Height, h = 12feet = (12x 0.305)metres = 3.66m
Area of triangle= 1/2 bxh
A = 1/2 x 1/3 x 3.66
A = 0.61m^2
Or in feet's
Area of triangle = 1/2 bxh
A = 1/2 x 1/3 x 12 =2 feet^2
Answer:
-8
Step-by-step explanation:
1^2=1
-4 x -1 =-4
-4 - 1 -3 = -8
Plug in 1 where there is x
