Answer:
a = 12cm
Third option
Step-by-step explanation:
Use the pythagorean theorem because this is a right triangle and you are looking for a missing side.
The formula is:
a² + b² = c², where "a" and "b" are sides, but "c" is the hypotenuse (longest side).
We know the hypotenuse and one other side.
Substitute side "b" and "c".
a² + 5² = 13²
a² + 25 = 169 Isolate "a"
a² = 169 - 25 Subtract 25 from both sides
a² = 144 Find the square root of both sides
a = √144
a = 12
The mssing side, "a", is 12 cm long.
Answer:
12 square cm correct to 2 significant figures
Step-by-step explanation:
Area of a Rectangle = L X B = 2.1 X 5.6 = 11.76 square cm
To round your result to 2 significant figure, we start counting from the left from the first non-zero digit.
The first two digits are 11 but because the number after is 7 (greater than 4), we round up to 12.
11.76 square cm = 12 square cm correct to 2 significant figures
The probability that the result is green - tail is 1/6.
Spinner has three colors that are red, green and yellow and coin has two sides that are head or tail.
<h3>What is the formula for probability?</h3>
Divide the number of events by the number of possible outcomes
The sample space is,
In total there are 6 ways to combine different colors with coin sides.
Therefore ,the probability that the result is green - tail is 1/6.

What I did was turn ¾ in to a fraction (which is 75%) then turned it into a decimal (.75)
then I multiplied .75 by 1.20 and .9
