Hi there!
To solve this problem, we need to multiply each number by 4 ft.
8×4=32
5×4=20
Now, we films the area.
32×20 = 640
The area of the room is 640 feet squared.
Hope this helps!
A = (1/2)base*height
Since this is an equilateral triangle each side is 34 inches, the altitude bisects the base into two 17 inch segments
There is now a right triangle with a base of 17 inches and a hypotenuse of 34 inches, so the pythagorean theorem (a^2 + b^2 = c^2) can be used
17^2 + b^2 = 34^2
or b^2 = 34^2 - 17^2
b^2 = 867 (take the square root of both sides)
b = 17
so the height of the equilateral triangle is 17
A = (1/2)(34)(17
)
A = 500.56 square inches
Answer :
C
Explanation:
It is C because it simplifies down to 5x+5x.
Answer: a = 150
b = 30
Remember: supplementary angles always add up to 180 degrees. Therefore, using this information, you can easily form your equation.
Form your equation. Since a is five times b, a = 5b.
5b + b = 180 Combine like terms
6b = 180 Divide by 6 to both sides
b = 30 Answer!
Substitute (30) for b in a = 5b to find a.
a = 5(30) Simplify
a = 150 Answer!
Answer: Let E be the event that the first marble selected is green. Let F be the event that the second marble selected is green. A box contains 20 blue marbles, 16 green marbles and 14 red marbles P(F/E)=15/49 because if the first marble selected is green there are 49 in total and 15 are green. I think this is it.
