PLEASE HELP GEOMETRY
Taya2010 [7]
The distance formula is sqrt((x1-x2)^2 + (y1-y2)^2), therefore (3-(-6))^2 = 9^2 and (5 -(-6))^2 = 11^2 so 121 + 81 = sqrt(202), this converted to decimal is ~14.21, so D.

The probability of spinning an odd number, flipping heads and then spinning a 3 is?
Olenka [21]
<h3>Answer:  5/162</h3>

===================================================

Work Shown:

A = probability of landing on an odd number

A = 5/9 because there are 5 odd numbers out of 9 total

B = probability of getting heads

B = 1/2

C = landing on 3 on the spinner

C = 1/9

Multiply the values of A,B,C

A*B*C = (5/9)*(1/2)*(1/9) = (5*1*1)/(9*2*9) = 5/162

Note: The fraction 5/162 converts to the approximate decimal 0.03086 which then converts to 3.086%, when rounding to the nearest tenth of a percent we get 3.1%

The length of a rectangle is (x plus 3) inches long, and the width is 3 2/5 inches. If the area is 15 3/10 square inches, write
IgorC [24]

Answer: Explained in the step-by-step


Step-by-step explanation:

We want to isolate x, and remember, what we do to one side we do to the other:

(x+3) * 3  2/5 = 15  3/10

(x+3) * 3  2/5 divided by 3  2/5 = 15  3/10  divided by 3  2/5

x + 3 = 153/10 * 5/17

x + 3 = 765/170

x + 3 = 153/34

x + 3 = 4.5

x + 3 - 3 = 4.5 - 3

x = 1.5

Check:

(1.5+3) * 3  2/5 = 15  3/10

4.5 * 3  2/5 = 15  3/10

(3  2/5 = 3.4 and 15  3/10 = 15.3)

4.5 * 3.4 = 15.3

15.3 = 15.3
