Answer:
210 1/8 ft²
Step-by-step explanation:
The length of the living room is 20 1/2
the width is half as long as the length
(20 1/2)/2=10 1/4
so the width is 10 1/4
A=LW so
A=(10 1/4)(20 1/2)
So A=
210 1/8 ft²
Answer: E) 1/5
Step-by-step explanation:
The probability of any member being selected for each of the 3 posts is 1/10 that is they have equal probabilities of being selected for any of the posts.
The probability that harry would be selected for;
Secretary Ps= 1/10
Treasurer Pt = 1/10
So the probability of being selected for either secretary or treasurer is
P = Ps + Pt
P = 1/10 + 1/10
P = 2/10
P = 1/5
Note: ignore the sequence of selection
If Car A's speed is x, then Car B's speed is x-22. Using the formula, we get that the distance is the same in both, so 4*(x-22)=D and 2.4*x=D due to that we plug 2.4 and 4 in for T and x-22 and x for R. Since they both equal D, we can write it as 2.4*x=4*(x-22). Using the distributive property, we get 4*(x-22)=4x-88=2.4*x. Subtracting 2.4*x from both sides as well as adding 88, we get 1.6*x=88. Dividing both sides by 1.6, we get 88/1.6=55= x=Car A's speed
