Answer:
<u>Secant</u>: a straight line that intersects a circle at two points.
<u>Intersecting Secants Theorem</u>
If two secant segments are drawn to the circle from one exterior point, the product of the measures of one secant segment and its external part is equal to the product of the measures of the other secant segment and its external part.
From inspection of the given diagram:
- M = Exterior point
- MK = secant segment and ML is its external part
- MS = secant segment and MN is its external part
Therefore:
⇒ ML · MK = MN · MS
Given:
- MK = (x + 15) + 6 = x + 21
- ML = 6
- MS = 7 + 11 = 18
- MN = 7
Substituting the given values into the formula and solving for x:
⇒ ML · MK = MN · MS
⇒ 6(x + 21) = 7 · 18
⇒ 6x + 126 = 126
⇒ 6x = 0
⇒ x = 0
Substituting the found value of x into the expression for KL:
⇒ KL = x + 15
⇒ KL = 0 + 15
⇒ KL = 15
Answer:
The dimensions of the pool on the blueprint would be 3 in wide by 4.5 in long.
Step-by-step explanation:
First I turned 3/4 into a decimal, which would be 0.75. The I divided the dimensions of the pool by two. This way I could multiply the .75 by how many sets of two feet there were in the dimensions. Finally I multiplied 4 by .75 and I multiplied 6 by .75. That is how I found my answer.
Well, first you need to decide what place you want to round it TO.
Example: Round it to the nearest hundredth:
The next larger hundredth is 186.29 .
The next smaller hundredth is 186.28 .
Now look at it.
186.282 is closer to 186.28 than it is to 186.29 .
So the nearest hundredth is 186.28 .
-- When 186.282 is rounded to the nearest hundredth, it becomes 186.28 .
Similarly . . .
-- When 186.282 is rounded to the nearest tenth, it becomes 186.3 .
-- When 186.282 is rounded to the nearest whole number, it becomes 186 .
-- When 186.282 is rounded to the nearest ten, it becomes 190 .
-- When 186.282 is rounded to the nearest hundred, it becomes 200 .
-- When 186.282 is rounded to the nearest thousand or anything larger,
it becomes zero.
I'm curious . . . where did this number come from ?
It happens to be one thousandth of the speed of light, in miles per hour.
Did it come up in science class, or did a science geek use it for
one of the problems in math ?
Answer:
<h3>Rational number</h3>
Step-by-step explanation:
A rational number are number that can be written as the ratio of two integers. Integers are whole numbers and they can be positive or negative including zero.
Looking at the value 5.371, we can write it in fraction form as shown;
5.371 = 5371/1000
Since 5.371 is equivalent to 5371/1000 and <em>5371/1000 is a ratio of two integers 5371 and 1000 therefore we can conclude that 5.731 is a rational number</em>
<u>Note that decimal numbers are not integers and are not whole numbers.</u>
