5 2/3 × 2 3/5 = 5 6/15 answer

Just add 5 2/3 to 2 3/5!
the answer is 8 4/15
workings: you can convert the fractions to an improper fraction and add them, it would be easier!
5 2/3 > 17/3 (eq 1)
2 3/5 > 13/5 (eq 2)
after conversion, you must make the denominator the same, the common multiple is 15
take eq 1 multiply by 5 > 85/15
take eq 2 multiply by 3 > 39/15
85/15 + 39/15 = 124/15!!
124/15 convert back to mixed fraction > 8 4/15
hope it helped :D

What is the angles mSRW?
Scilla [17]

Answer:

126°

Step-by-step explanation:

(2x +18)° = (3x)°

2x + 18 = 3x

18 = 3x - 2x

18 = x

therefore, (3x)° = (3*18)°= (54)°

m\angle SRW + (3x)\degree = 180\degree \\m\angle SRW + 54\degree  = 180\degree \\m\angle SRW = 180\degree  - 54\degree  \\\huge\red{\boxed{m\angle SRW = 126\degree}}

I'm trying to rearange this equation so that t is the subject and i need help
gregori [183]
Work backwards.

s=ut+(at^2)/2

Subtract ut.

s-ut=(at^2)/2

Multiply by 2.

2(s-ut)=at^2

Divide by a.

2(s-ut)/a=t^2

Find the square root:

\sqrt{2(s-ut)/a}=t

A,B,C, and D are all answer choices
ruslelena [56]

Answer:

Empirical formula

0.34

0.33

0.33

A^c = event B or event C

Step-by-step explanation:

A = roommate A wins the game

P(A) = (Rock A and Scissors B) + (Scissors A and paper B) + (paper A and rock B)

P(A) = (0.36*0.53) + (0.32*0.25) + (0.32*0.22) = 0.3412

C = game ends in a tie :

P(C) = (RockA and rockB) + (ScissorsA and ScissorsB) + (ScissorsA and ScissorsB)

P(C) = (0.36*0.22) + (0.32*0.53) + (0.32*0.25) = 0.3288

P(B) = 1 - P(A) - P(C)

P(B) = 1 - 0.3412 - 0.3288

P(B) = 0.33

Complement of event A =event B or event C
