Answer:

The probability of the spinner landing on A is 0.1111.

Step-by-step explanation:

The possible outcomes of a board game is that it can lead on any three of the regions, A, B and C.

The probability of all the outcomes of an event sums up to be 1.

P(E) = P(E_{1})+P(E_{2})+...+P(E_{n})=1

According to the provided information:

P (B) = 3 P (A)

P (C) = 5 P (A)

Compute the probability of the spinner landing on A as follows:

P(A)+P(B)+P(C)=1\\P(A)+3P(A)+5P(A)=1\\9P(A)=1\\P(A)=\frac{1}{9}\\=0.111111\\\approx0.1111

Thus, the probability of the spinner landing on A is 0.1111.

2.5(t - 2) - 6 = 9 (solve for the unknown variable)
Elis [28]

2.5(t - 2) - 6 = 9

2.5(t - 2) = 9 + 6 = 15

t - 2 = 15/2.5 = 150/25 = 6

t = 6 + 2 = 8

Answer: 8

Check: 2.5(8 - 2) - 6 = 2.5(6) - 6 = 1.5(6) = 9  good

klio [65]

Answer: 40.5 square feet

Step-by-step explanation:

Given : Zhi needs new flooring for her two laundry rooms.each room is 4.5 feet long and 4.5 feet wide .

We assume that the room is rectangular in shape .

Area of rectangle = Length x width

Then area of one laundry room = 4.5  feet x 4.5 feet = 20.25 square feet

Area of two laundry room = 2 x 20.25 = 40.5 square feet.

Hence, The flooring need to cover a total of <u>40.5 square feet</u> of area.
