The slope of the line passes through (10,3) and (1,2) is  \frac{1}{9}

Step-by-step explanation:

Given:

Two points are (10,3) and (1,2)

To find:

The slope of the line passes through (10,3) and (1,2)

Formula to be used:

Slope m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Solution:

Let "m" be the slope of the given points (x_{1} y_{1}) and (x_{2} y_{2})

Here,

x_{1} = 10, y_{1} = 3, x_{2} = 1 and y_{2} = 2

Substituting all the above vales we get,

m = \frac{2-3}{1-10} = \frac{-1}{-9} = \frac{1}{9}

Hence, the slope of the line passes through (10,3) and (1,2) is  \frac{1}{9}

Find the surface area of the triangular prism (above) using its net (below).
r-ruslan [8.4K]

Answer:

96 square units

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo.

My answer:

  • The length of the large rectangle is: 5
  • The width of the large rectangle is: 7

=> Area of the large rectangle = length × width  = 7*5 = 35 square units

  • The length of the middle rectangle is: 7
  • The width of the middle rectangle is: 4

=> Area of the middle rectangle = length × width  = 7*4 = 28 square units

  • The length of the small rectangle is: 7
  • The width of the small rectangle is: 3            

=> Area of the small rectangle = length × width  = 7*3 = 21 square units

Area of top and the bottom triangles =2* \frac{1}{2}bh  = 4*3 =12  

Total surface area = 35 + 28 + 21 + 12 = 96 square units

pashok25 [27]

Answer:

0.105 = 10.5% probability that an accident results in a death.

Step-by-step explanation:

What is the probability that an accident results in a death?

5% of 60%(sunny)

25% of 20%(foggy)

12.5% of 20%(rainy)

So

p = 0.05*0.6 + 0.25*0.2 + 0.125*0.2 = 0.105

0.105 = 10.5% probability that an accident results in a death.

A factory adds three red drops and two blue drops of coloring to white paint to make each pint purple The factory will make 50 g
Radda [10]

30 gallons of red paint  &  20 gallons of blue paint

Step-by-step explanation:

The ratio of red to blue paint drops to make purple paint is 3 : 2

Therefore the total number of gallon, in this case, fifty (50) is equivalent to the total of two ratios (which is 3 + 2 5)

If 5 in the ratio = 50; what about 2  & 3

5 = 50

2 = x

After cross multiplication;

5x = 50 * 2

X = 100/5

X = 20

The same for ratio 3

5 = 50

3 = y

5y = 50 * 3

y = 150/5

y = 30

The answer is therefore; 30 gallons of red paint to 20 gallons of blue paint
