Answer: The correct option is (B) 3.
Step-by-step explanation: We are given to find the length of the leg s in the triangle shown in the figure.
From the figure, we note that
the given triangle is a right-angled one, where
length of the hypotenuse, H = √18 units,
length of one leg, P = 3 units
and
length of the other leg, s = B =?.
From Pythagoras theorem, we have
Thus, the length of the leg s is 3 units.
Option (B) is CORRECT.
Answer:
8 inches
Step-by-step explanation:
Let l represent the length of the square
The area of a square = l^2
That means,
l^2 = 24 km^2
Take the square root of both sides
l =
l =
l =
l = 2
Now lets find the perimeter
Perimeter of a square, P = 4l
P = 4* 2
P = 8 inches
For the numeric part, you'll have to find the GCD of 15 and 25, which is 5. So, we can factor a 5 and we have
As for the literal part, you can factor because it's the power of s with the smallest denominator. So, we have
Answer:
Q6. D
Q8. A
Step-by-step explanation:
Q6. In 40 trials, he flipped '2 heads and 1 tail' 16 times.
For 2 heads, probability= 16/40= 4/10
For 120 trials, number of times= 4/10 × 120= 48
Q8.
Answer is A because the inequality shows that x is equal or greater than 8 so the dot at 8 has to be coloured.
Note that we do not change the inequality sign unless we are dividing the whole thing by -1.
