Answer:
The size of the angle formed at the top of the sail is 35.
Step-by-step explanation:
We know that the sum of all angles inside a triangle must be 180. This is a rule.
So we know that a right triangle is called like that because one angle is a 90-degree angle.
Then we have that:
180 = right angle + lower edge angle + angle top of the sail
180 = 90 + 55 + angle top of the sail
Solving for 'angle top of the sail' we have:
angle top of the sail = 180 - 90 - 55 = 35
The size of the angle formed at the top of the sail is 35.
Answer:
Part A: 90; Part B: 24.
Step-by-step explanation:
The number of blueberry muffins is 40% of the total number of muffins.
Part A: There are 36 blueberry muffins. This is 40% of the unknown number of muffins, x; this gives us
36 = 0.4x
Divide both sides by 0.4:
36/0.4 = 0.4x/0.4
90 = x
There were 90 total muffins.
Part B: 40% of the total number of muffins, 60, gives us the unknown number of blueberry muffins:
0.4(60) = x
24 = x
There were 24 blueberry muffins.
8,425 ÷ 10.25 = 821.95
You would round up so to earn $8,425 you would need to work 822 hours
Answer: D) P(x) = -23
Step-by-step explanation:
Substitute 2 for x:
1 - 2(2)^2-3(2)^2+4(2)
Exponent
1-2(4)-3(8)+4(2)
Multiply
1-8-24+8
Combine like terms
-23
