Answer:

0.973

Step-by-step explanation:

Solution

I'm going to discuss one way to do it, and then show a much better way.

If you attack the problem directly, there are 3 ways of placing just 1 day not being late

0.7 * 0.3 * 0.3  = .063

0.3 * 0.7 * 0.3 =  .063

0.3 * 0.3 * 0.7  = 0.63

Making it on on time on two days gives you 3 equations as well

0.7* 0.7 * 0.3 = .147

0.7* 0.3 * 0.7 = .147

0.3 * 0.7 * 0.7 = .147

Making it on time all three days

0.7 * 0.7 * 0.7 = .343

If you add add these up, you should get 0.973

There is a better way. First calculate what happens if he is late all three days.

0.3 * 0.3 * 0.3 = 0.027     No on times (.7) anywhere.

If you take 0.027 away from 1, you get 0.973 That takes care of all the times he was on time. Much neater and easier, no?

Step-by-step explanation:

The label on the cone that represents the diameter of the cone is the letter C

From the figure in the complete question, the line C divides the base circle into two equal segments

The above is the same as the definition of the diameter

Hence, the label that represents the diameter of the cone is the letter C

C is the correct Answer

Step-by-step explanation:

The value of the a and b will be 6 and 9 feet. Every 2 inches on the scale drawing represents 1.5 feet of the original house.

The process of converting the unit form is known as the unit conversion. For example, in the SI unit system, mass is in kg. While in CGS, it is represented in grams.

The given conversion is ;

[tex]\rm 2 \ inch = 1.5 \ feet \\\\ 1 inch = \frac{1.5}{2} \ feet[/tex]

For 8, 12 inches, the values in feet is;

[tex]\rm 8 \times \frac{1.5}{2} = 6 \ feet[/tex]

[tex]\rm 12 \times \frac{1.5}{2} = 9 \ feet[/tex]

Hence, the value of the a and b will be 6 and 9 feet.

The value a= 6 and b=9.

The process of converting the unit form is known as the unit conversion.

For example, in the SI unit system, distance is in meter while in CGS, it is represented in cm.

Given that:

2 inch = 1.5 feet

1 inch = [tex]\frac{1.5}{2}[/tex]

then, 8 inches =[tex]\frac{1.5}{2} *8[/tex]

                        = 1.5*4

                        = 6 feet

again, 12 inches= [tex]\frac{1.5}{2} *12[/tex]

                          = 1.5*6

                         = 9 feet

and, 16 inches =[tex]\frac{1.5}{2} *16[/tex]

                          = 1.5*8

                          = 12 feet

The volume of a cylinder with a height of 12 millimeters and diameter of 18mm is 972π mm^3

The formula for calculating the volume of a cylinder is expressed as:

V = πr²h where:

r is the radius

h is the height

Given the following parameters

h = 12mm

r = 18/2 = 9mm

Substitute

V = π(9)²(12)
V = 972π mm^3

Hence the volume of a cylinder with a height of 12 millimeters and diameter of 18mm is 972π mm^3

Answer:

C

Step-by-step explanation:

Answer:

1) yes--common difference is 3.

Considering the circumference of the circle, it is found that the length of arc AB is of 3.1 meters.

The circumference of a circle of radius r is given by:

[tex]C = 2\pi r[/tex].

This measure is equivalent to the length of an arc of 360º.

In this problem, we have that the radius is of r = 3m, hence the circumference is given by:

C = 6 pi m.

Arc AB has an angle of 60º, hence it's length is 1/6 of the circumference, which will then be of pi m = 3.1 meters.

Step-by-step explanation:

Answer:

Jeff, 4.5 hours; Julia 9 hours.

Step-by-step explanation:

To solve the problem, we need to write two equations using the given information.

So, writing the first equation we have:

We know that Jeff can weed the garden twice as fas as his sister Julia, so:

Also, from the statement we know that they can weed the garden in 3 hours, so, writing the second equation we have:

Then, we need to substitute the first equation into the second equation in order to isolate Julia's rate, so, solving we have:

We have that Julia could weed the garden by herself in 9 hours.

So, calculating how long will it take to Jeff, we have:

We have that Jeff could weed the same garden by himself in 4.5 hours.

If the height of a right triangular prism is 1 5/6 inches. The surface area of the solid formed is: 598.33 in².

First step

Right triangular prism=1 5/6 inches= 11/6 inches

Height of the base=8 2/3 inches = 26/3 inches

Second step

Surface area = 5(10× 10) + (0.5÷ 10 × 26/3) + 3(10× 11/6)

Surface area = 5(100) +43.33+ 3(18.33)

Surface area = 500) +43.33 + 55

Surface area = 598.33 in²
