Find the area of the square first
Area = Length x Width
Area = 12 x 9
Area = 108
Find the area of the right triangles
Area = 1/2(Length x Base)
Area = 1/2(9 x 2)
Area = 1/2(18)
Area = 9
Since there is 2 triangles multiply by 2
9 x 2 = 18
Now add
108 + 18 = 126
126 is your area
I'm ASSUMING this is a 45-45-90 right triangle and that DF is the hypotenuse.
With that said. Angle F = 45 means that angle = 45 and angle E = 90 degrees.
There is only one rule for 45-45-90 right triangles:
hypotenuse = √(2) * leg
Given the hyp = 16
16 = √(2) * leg
divide both sides by √(2)
16/√(2) = leg
Rationalize the denominator
16√(2)/(√(2)*√(2) =
(16√(2)) / 2 =
8√2
Answer:
Step-by-step explanation:
We have the two points: (0, 11) and (3, 50).
And we want to find the rate of change in y relative to x, where x is the gallons and y is the miles.
In simple terms, we want to find the slope between the two points.
So, let's use the slope formula:
Let (0, 11) be (x₁, y₁) and let (3, 50) be (x₂, y₂). Substitute. Let's also put "miles" in the numerator with the Ys and "gallons" in the denominator with the Xs. This yields:
Subtract and reduce:
And we're done!
Answer:
1. 10%
2. 49.1%
Step-by-step explanation:
1. The percent of voters who are other is the number of other divided by the total number of voters.
The number of "other" votes is 222. The number of total votes is 2,222.
The percent is 222/2222 = 0.0999. Times the decimal by 100 for the percent.
0.0999*100 = 9.99% rounds to 10%.
2. The probability is found by finding the number of male and registered as democrat, which is 600, and dividing it by the number of males, which is 1,222.
600/1,222 = 0.4909
Multiply by the decimal by 100 to find the percent.
0.4909*100 = 49.09 which rounds to 49.1%.
