The probability that Jason has blue socks is \frac{5}{51}

<u>Solution:</u>

Given, there are 12 brown socks and 6 blue socks in a drawer.  

So, total number socks = 12 + 6 = 18 socks

In the dark, Jason pulls out a sock and puts it on his right foot.  

Now, let the probability of pulled sock to be blue sock

=\frac{\text {number of blue socks}}{\text {total number of socks}}=\frac{6}{18}=\frac{1}{3}

Then, available socks = 18 – 1 picked sock = 17 socks and number of blue socks = 6 – 1 = 5

Then he pulls out another sock and puts it on his left foot

Now, the probability that second picked sock will also be blue = \text { probability of } 1 \text { sock } \times \frac{\text { blue socks count }}{\text { socks count }}

=\frac{1}{3} \times \frac{5}{17}=\frac{5}{51}

Hence, the probability that Jason has blue socks is \frac{5}{51}

When angles are complementary, the sum of their measures is 90 degrees.Two complementary angles have measures of 2x-10 degrees a
Mariana [72]

Complementary angles are those angles whose sum is 90 degree.

The measurement of two complementary angles are

(2x-10), (3x-10)

There sum have to be 90 degree. That is

2x-10+3x-10 = 90

Combining like terms ,

5x - 20 = 90

Moving 20 to right side

5x=110

Dividing both sides by 5

x =22

So the measurement of the angles are

2*22-10 , 3*22-10  \\&#10;34 degree,  56 degree

13. Find the surface area of each figure to the nearest tenth. Show your work.
stiv31 [10]
A. The figure is a triangular pyramid. You can findits surface area by adding up the area of the three faces of the triangle and the area of the base. A derived formula also is used where the SA is equal to 12 times the perimeter of base times the slant height, added to that is the area of the base. The area of the square base is s^2. Its perimeter is 4s.

SA of Pyramid = 12*P*l + s^2
SA of Pyramid = 12*4s*l + 16^2
SA of Pyramid = 12*4(16)*(17) + (16)^2
SA of Pyramid = 11,008 square inches

b.) The formula for the SA of a cone is: 

SA of cone = πr[r+√(h^2+r^2)]
SA of cone = π(3)[(3+√(8^2+3^2)]
SA of cone = 108.8 square inches

If a rectangular prism was 5 feet long, 5 feet high and 6 feet deep, how much would it weigh if one cubic foot weighed 0.1 tons?
padilas [110]

Answer:

Total weight = 1,500 tons

Step-by-step explanation:

Given:

l = 5 ft

b = 5 ft

h = 6 ft

One cubic foot weighed = 0.1 tons

Find:

Total weight

Computation:

Volume = lbh

Volume = (5)(5)(6)

Volume = 150 ft³

Total weight = Volume / 0.1

Total weight = 150 / 0.1

Total weight = 1,500 tons
