A Picture Shows The Net Of The Lateral Surface Of The Cone. Which Statement About This Cone Is NOT True?

Answers

Answer 1

Answer:

Area of the Net is incorrect

Step-by-step explanation:

Base Surface Area =  π×12^2

=  452.38934211693 inches^2

Lateral Surface Area =  π×12×√12^2 + 15^2

=  724.1762903163 inches^2

Total Surface Area = 1176.5656324332 inches^2

An insector found 24 defective cameras during an inspection. If this is 0.016% of the total numbers of cameras inspected. How many cameras were inspected? ​

Answers

Answer:

150,000.

Step-by-step explanation:

Given that an insector found 24 defective cameras during an inspection and this is 0.016% of the total numbers of cameras inspected, to determine how many cameras were inspected the following calculation must be performed:

0.016 = 24

100 = X

100 x 24 / 0.016 = X

2,400 / 0.016 = X

150,000 = X

Thus, the total number of cameras that were inspected is 150,000.

The following problem describes procedures that are to be applied to numbers. Repeat the procedure for four numbers of your choice. Write a conjecture that relates the result of the process to the original number selected. Select a number. Multiply the number by 88. Add 88 to the product. Divide this sum by 44. Subtract 2 from the quotient.

Answers

Answer:

Conjecture: For every number x, the result of the is 2x

Step-by-step explanation:

First Number: 8

Multiply by 88: [tex]88 * 8 = 704[/tex]

Add 88: [tex]704 + 88 = 792[/tex]

Divide by 44: [tex]792/44 = 18[/tex]

Subtract 2: [tex]18 - 2 = 16[/tex]

Second: 10

Multiply by 88: [tex]88 * 10 = 880[/tex]

Add 88: [tex]880+88=968[/tex]

Divide by 44: [tex]968/44=22[/tex]

Subtract 2: [tex]22-2=20[/tex]

Third: 5

Multiply by 88: [tex]88*5 = 440[/tex]

Add 88: [tex]440+88=528[/tex]

Divide by 44: [tex]528/44=12[/tex]

Subtract 2: [tex]12-2=10[/tex]

Fourth: 2

Multiply by 88: [tex]88*2=176[/tex]

Add 88: [tex]176+88=264[/tex]

Divide by 44: [tex]264/44=6[/tex]

Subtract 2: [tex]6-2=4[/tex]

On a general terms:

Let the number be x.

Multiply by 88: [tex]88x[/tex]

Add 88: [tex]88x + 88[/tex]

Divide by 44: [tex]\frac{88x + 88}{44} = \frac{88x}{44} + \frac{88}{44} = 2x+2[/tex]

Subtract 2: [tex]2x + 2 - 2 = 2x[/tex]

Notice that for every input x, the result is 2x

An airline company does not charge an extra fee if the weight of a passenger's luggage is less than 55 pounds.

Part A
On the number line, represent the values when the airline company does not charge an extra fee.

Part B
Create an inequality that represents this situation. Let p represent the weight of a passenger's luggage

Answers

Answer:

Let's solve first the part B.

We know that the company does not charge an extra fee is the luggage is less than 55 pounds.

Then if p represents the weight of the passenger's luggage, we need to have:

p is smaller than 55 lb

We also can write this as:

p < 55lb

where the symbol "<"

means that the left side is strictly smaller than the right side.

If we want to be more precise in the notation, we also should have a lower limit.

0lb < p < 55lb

Where the lower limit is because the weight of the luggage can not be zero or smaller than zero.

This is the inequality we wanted.

Now, how we represent this on a number line?

when we have:

x > a

We represent this with a open circle at x = a (this means that x = a is not a solution) and we draw an arrow to the right of a.

and for:

x < a

we represent this with an open circle at a, and we draw an arrow to the left of a.

And if we have:

a < x < b

we draw an open circle at x = a and another at x = b, and all the points between these circles will be solutions.

You can see the graph of the inequality below.

Part A)

(where the point of the arrow should not be there, and both circles should be white)

Answers

Answer: 7x+28=119

x=13

Step-by-step explanation:

Answer:

119= 7x + 28

x=13

Step-by-step explanation:

This problem requires an equation. y= mx+ b, where y is your total, mx is your slope, and b is your y intercept. Your total is 119, your yearly fee is 28 ( which is b since it only happens ones), and 7 is x (since x represents each time) So 119=7x+28. Now to solve this we would subtract 28 from both sides and then divide that number by 7. So 119-28 is 91. 91/7 is 13. He used the racketball court 13 times. You can plug 13 to make sure.

119= 7(13) + 28.
