Suppose that you spin the double wheel pictured to the right. Assuming that the wheels are independent and each outcome is equal

ly​ likely, determine the probability that you get red on both wheels.
A spinner consists of two concentric unequal circular wheels with the smaller one placed on the larger. The smaller wheel is divided into 8 equal sectors. The number of sectors for each color is as follows, where the label is listed first and the number of sectors is listed second: red, 3; blue, 2; yellow, 1; grey, 2. The larger wheel is divided into 12 equal sectors. The number of sectors for each color is as follows, where the label is listed first and the number of sectors is listed second: red, 4; blue, 2; yellow, 2; grey, 2; green, 2.

B=blue
G=green
Y=yellow
R=red
g=grey

The probability is:_________

Answer:

0.125

Step-by-step explanation:

<u>Smaller Wheel</u>

Total Number of Equal Sectors = 8

The number of Red sectors =3

The probability of obtaining red on the smaller wheel =\dfrac38

<u>Larger Wheel</u>

Total Number of Equal Sectors = 12

The number of Red sectors =4

The probability of obtaining red on the larger wheel =\dfrac{4}{12}

Assuming that the wheels are independent and each outcome is equally​ likely, the probability that we get red on both wheels

=\dfrac38 \times \dfrac{4}{12}\\\\=\dfrac18\\\\=0.125

The probability is: 0.125

Given 3 sides of a triangle - how to tell it right, acute, or obtuse 8,11, 16
user100 [1]
Using Pythagorean theorem, we can justify our answer.
if c^2 = a^2 + b^2 then triangle is right one,
if c^2 > a^2 + b^2 then triangle is obtuse and
if c^2 < a^2 + b^2 then triangle is acute triangle.

Here a=8, b=11 and c=16
Put these values in the equation
16^2 = 8 ^2 + 11^2
256 = 64 +121
256> 185
So here c^2 > a^2 + b^2  Which means triangle is obtuse triangle.

Answer: Obtuse Triangle

Take all the zero's away and multiply the numbers that are left.

which is 1*1=1 now add all of the zeros to that one which will turn it into

Hi everyone! I have a question!
Tju [1.3M]

Answer:

7π

Step-by-step explanation:

SO first find the area of the whole circle

which has a radius of 3

a=πr^2

So 3^2=9

9π

Now the two circles which are the same in area due to having the same radius

so if you plug in the 1 for radius the answer would just be π or 1π

now multiply that by 2 becuase there are 2 identical circles

π*2=2π

Now subtract

9π-2π=7π
