Answer:
base of 3 --> 3^4 (three to the fourth); base of 9 --> 9^2 (nine squared)
Step-by-step explanation:
<u>3 x 3</u> = 9 x <u>3</u> = 27 x <u>3</u> = 81 = 3^4
You multiply 3 by itself 4 times.
<u>9 x 9</u> = 81 = 9^2
You multiply 9 by itself 2 times.
Answer:
3:4
Step-by-step explanation:
find the GCD of both numbers (30) and divide both sides to get 3:4
Answer:
Step-by-step explanation:
in the first one 2,4,6,and 8 are equal meaning they all equal to 75. the other angles 1,3,5,and 7 equal 105 because 180 - 75 = 105
for the other ones i'm not sure srry
The height is 1943.8 feet. easiest way to do this is draw a little diagram. Draw the building and the unknown height can be "x". We know a 1000 feet away from the base of the building, the angle between the ground and top of the building is 11 degrees. If you draw this, you can see that you can use the tan function to find the missing "x". tan (angle) = opposite side/adjacent side. So tan(11) = x/1000. Isolate for x and you get 1943.8 feet
Answer:
1,000 cc = 1 liter
Volume of a cylinder = PI * radius^2 * height
(the "cylinder volume" is for one second of "flow")
Volume of a cylinder per sec = 3.14159 * 3.5^2 cm * 5 meters
Volume of a cylinder per sec = 3.14159 * 3.5^2 cm * 500 cm
Volume per second = 19,242 cubic cm which equals
19.242 liters
There are 60 seconds in a minute, so that means the volume per minute =
(19.242 * 60) = 1,154.52 liters / minute
