(-2.3)*4.7 would be equal to -10.81
Answer:
16
Step-by-step explanation:
We can use the Pythagorean theorem to find the height
a^2 + b^2 = c^2 with a and b legs and c the hypotenuse
The triangle is a right triangle with legs GH and FG and hypotenuse FH
FG^2 + GH^2 = FH^2
FG ^2 + 12^2 = 20^2
FG^2 +144 = 400
Subtract 144 from each side
FG^2 +144-144 = 400-144
FG^2 =256
Take the square root of each side
sqrt(FG^2) =sqrt(256)
FG = 16
-17/6 is the unequal fraction answer. To put it as a mixed number, you simply divide it like it's set up and put the remaining 'leftovers' as the fraction. 12 divided by six equals two, leaving us with five left over, so the answer is 12 5/6
Answer:
Yes
Step-by-step explanation:
The definition of a rational number is a number that can be represented as a fraction. Since 56/7 is a fraction it must be a rational number. An irrational number is a number that cannot be represented as a fraction because it never ends and repeats without a pattern forever. An example of this is pi because pi can never exactly be represented as a fraction.
-2.1 - (5.9 + 3.7)
Both equal -11.7 so that is the correct option.
