3 large pizzas because usually it would be more like 30$ or something
Use law of sines:
Cos(x) = adjacent/ hypotenuse
cos(x) = 8.8/13
X = arcsin(8.8/13)
X = 47.396 degrees
Rounded to the nearest tenth = 37.4 degrees
Answer:
1. 1/18
2.1/18
Step-by-step explanation:
In order to multiply fractions, you just multiply it straight out. Numerator to numerator, denominator to denominator.
1*1=1
6*3=18
So, the answer is 1/18.
To divide fractions, you flip the second number. If the number is 3, you flip the 3 to the denominator to make 1/3. Then, you multiply using the rule above.
Answer:
Problem 4: x = -11
Problem 5: x = -7
Step-by-step explanation:
<u>Problem 4:</u>
x + 51 + 60 + 80 = 180
x + 51 + 60 + 80 - 51 - 60 - 80 = 180 - 51 - 60 - 80
x = -11
Answer: x = -11
<u>Problem 5: </u>
45 + 52 + x + 90 - 90 - 52 - 45 = 180 - 90 - 52 - 45
x = -7
Answer: x = -7
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 )
