We can solve this by multiplying those two numbers but we place them in improper fraction.

2 1/2 x 2 1/4
becomes
5/2 x 9/4

for fraction multiplication, just multiply numerator by numerator and denominator by denominator

5/2 x 9/4 = 45/8

we can simplify this into mixed fraction while numbers in whole numbers and remainder in numerator

5 5/8 is the answer

A cube that has a volume of 1.00 m3 contains N distinguishable particles. Part A Determine the probability that all the particle
Sav [38]

Answer:

0.5

Step-by-step explanation:

Data provided:

Smaller Volume, V = 0.500 m³

Distinguishable particles, N = 1

Now,

the relation between the Probability of the particles, the volume and the number of distinguishable particles is given as:

P=V^N

where,

P is the probability

On substituting the respective values, we get

P = (0.500)¹

or

P = 0.5

Find q so that the lines y = (1 - 2q)x - 1 and (2 - q)y = x + 5 are perpendicular.
Stolb23 [73]

Answer:

q = 1.

Step-by-step explanation:

y = (1 - 2q)x - 1

The slope of this line is 1 - 2q.

(2 - q)y = x + 5

y = x / (2 - q) + 5/(2 - q)

The slope of this line is 1/ (2 - q).

When lines are perpendicular  the slopes m1 and m2 have the relation

m1 .m2 = -1, so

(1 - 2q) * 1/ (2 - q) = -1

1 - 2q = -2 + q

-3q = -3

q = 1.
