A= sides2
98=sides2
√98 = √(〖sides〗^2 )
Side= 9.8994
Now the Pythagorean theorem
a2 + b2 = c2
9.89942 + 9.89942 = c2
97.99812036+ 97.99812036 = c2
c2 = 195.99624072
c= 13.99
Rounded to the nearest whole number is 14
A. 14 m

Answer:

3rd option.

Step-by-step explanation:

$\frac{2|k|}{5}$ = 4

move 5 to the other side of the equation.

2|k| = 5(4)

2|k| = 20

move 2 to the other side of the equation.

|k| = $\frac{20}{2}$

k = 10

You roll a pair of six-sided number cubes, numbered 1 through 6. What is the probability of rolling two odd numbers? (Enter your

lbvjy [14]

Answer:

1/4 or 25%

Step-by-step explanation:

The probability for rolling an odd number is 50% or $\frac{1}{2}$ because there are 3 odd numbers, (1, 3, 5) and 6 total outcomes (1, 2, 3, 4, 5, 6). $\frac{3}{6} =\frac{1}{2}$

The probability for rolling two odd numbers in a row is

$\frac{1}{2} *\frac{1}{2} =\frac{1}{4}$

So, the probability of rolling an odd number twice is 25% or $\frac{1}{4}$ .
