Answer:
136 m2 Option c
Step-by-step explanation:
136 m2
1 base = 6 × 7 = 42
2 sides = 2(7 × 5) = 70
2 triangles = 2(6 × 4
2
) = 24
SA = 42 + 70 + 24 = 136 m2
Answer:
of the 4 people that have a sister, 2 of them have a brother
Step-by-step explanation:
probability of B given A
given that the person has a sister, what is the probability they have a brother
P (B/A) = 1/2
with this venn diagram
of the 4 people that have a sister, 2 of them have a brother
Tgα = tan(α) = sqrt(2)/1 = opposite/ adjacent
opposite = sqrt(2)
adjacent = 1
hypotenuse = sqrt(opposite^2 + adjacent^2)
= sqrt(sqrt(2)^2 + 1^2) = sqrt(3)
sin(α) = opposite/hypotenuse
= sqrt(2)/sqrt(3)
cos(α) = adjacent/hypotenuse
= 1/sqrt(3)
now we can calculate the value of
5sin²α+3cos²α / 3sin²α-5cos²α
... do the math
Your answer is E. $25.
First let under 12 = u, over 12 = o, and adults = a.
We can now write the equations:
2u + 3a + 3o = 174
4u + 2a = 122
a + o = 46
Because we know that a + o = 46, and 3a + 3o is in the first equation, we can multiply 46 by 3 to get what 3a + 3o equals. This makes 138.
Now we can substitute 138 into the first equation to get 2u + 138 = 174
2u = 36
u = 18
Now that we know what u equals, we can substitute it in to the second equation to get:
4(18) + 2a = 122
72 + 2a = 122
2a = 50
a = $25
I hope this helps! Let me know if you have any questions :)
Answer:
x = - 9
Step-by-step explanation:
Given g(x) = - x - 3 and g(x) = 6, then equate, that is
- x - 3 = 6 ( add 3 to both sides )
- x = 9 ( multiply both sides by - 1 )
x = - 9
