Answer:
[tex]\frac{85}{800}[/tex] or [tex]\frac{17}{160}[/tex] simplified
Step-by-step explanation:
In order to find the probability of this sequence of events happening we first need to find the probability of each event happening seperately and then multiply them together.
If there are 40 slip-joint pliers and only 5 are 6-inch then the probability of picking a 6-inch plier is 5/40. If there are a total of 20 rubber malets and only 3 are small then the probability of picking a non-small rubber mallet would be 17/20... Now we simply multiply these two probabilities together...
[tex]\frac{5 *17}{40 * 20}[/tex] = [tex]\frac{85}{800}[/tex] or [tex]\frac{17}{160}[/tex] simplified

An amusement park has a two merry-go-rounds. The first merry-go-round has a circular platform with a diameter of 13 meters. The second merry-go-round has a circular platform with a diameter of 19 meters. What is the difference between the areas of the larger and smaller merry-go-round’s platform?
Answer:
150.72
Step-by-step explanation:
Area of circle formula is r²π
Do find radius you do d/2, diameter/2. 13/2= 6.5
6.5 * 6.5 = 42.25
π is also known as 3.14
42.25 * 3.14 = 132.665
That is the area of the smaller one.
For the larger one, 19/2 = 9.5
9.5 * 9.5 = 90.25
90.25 * 3.14= 283.385
Now you subtract both of them and the difference is 150.72.
Hope this helps !!

Answer
150.72 m2
Step-by-step explanation:
Find the radius of the larger
merry-go-round.
19^2 = 9.5
Substitute 9.5 for r in the formula for the
area of a circle.
A-n • 9.52
= 71 -90.25
- 283.385
Find the radius of the smaller
merry-go-round.
13-^-2-6.5
Substitute 6.5 for r in the formula for the
area of a circle.
A~n • 6.52
= n - 42.25
-132.665
Subtract the area of the smaller merry go-round from the area of the larger
merry-go-round.
283.385 - 132.665 = 150.72

Where would I start when rewriting polynomials in standard form? I have my notes but they’re still unclear to me.
Answer:
Step-by-step explanation:
standard form = combine like therms and degrees drop from left to right
In this there aren’t like therms, so:
6x^3+x^2-9x+5
therms = each therm is seprated by a plus or a minus
in this case there are 4 therms
degree = look at the monomial with the highest degree
in this case is 3
Name = in this case there are four therms so it is a quadrinomial
Standard form denotes to arranging according to degrees or exponents
Standard form
6x³+x²-9x+5Number of terms=4
Degree=3
Name Quadrinomial or Biquadratic

Answer:
result = 0 + 2 - 4
Step-by-step explanation:
The leftmost arrow starts at 0 and goes 2 units in the + direction. The right arrow starts from there and goes 4 units in the - direction.
The left arrow represents adding 2 units to 0. The right arrow represents adding -4 units to +2, or subtracting 4 units from +2. The equation could be written as ...
result = 0 +2 -4
result = 0 +2 +(-4)
__
Additional comment
There are additional ways to write this in consideration of the fact that +2 = -(-2). The 0 doesn't need to be part of the equation. It is put here to indicate the fact that we start from 0. Without it, the "starting from 0" is implied.

When a child flying a kite has let out 60 meters of string, the string makes an angle of 60 degrees. How high is the kite?
Answer:
The height is: [tex]h = 51.96cm[/tex]
Step-by-step explanation:
Given
[tex]L = 60m[/tex]
[tex]\theta = 60[/tex]
Required
The height of the kite
See attachment for illustration.
To calculate height (h), we have:
[tex]\sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]
This gives
[tex]\sin(60) = \frac{h}{60}[/tex]
Make h the subject
[tex]h = 60 * \sin(60)[/tex]
[tex]h = 60 * 0.8660[/tex]
[tex]h = 51.96cm[/tex]

Are you against animal testing? If so, why?
Answer:
I am against testing on animals.
Step-by-step explanation:
Personally based on my faith humans are told to make the earth their dominion. To dominate doesn't only mean to use to one's advantage but to also take care of and replenish any loss caused by unintentioned damage. Animals do have feelings, both emotional and physical, and though those feelings may not be quite as developed as those of humans, they are undoubtedly existent. With how far technology has come when it comes to predictability and how calculated and concise science experiments have become, if as the most advanced species on earth we are still unable to determine how long a deodorant or lipstick or eyeliner would last without torturing other species, then what exactly have we achieved, and are we truly any more advanced than we were 10000 years ago? And for things that quite necessarily do need testing like vaccines and medicines it is to some extent understandable, but then again if the death sentence still exists for offenders of heinous crimes , why don't we instead of killing those criminals dedicate them to science and research for testing of vaccines and medicines. That way we all benefit from it. They don't have to die and neither do the animals and neither do we. It's a far stretch of a solution but alternatives can be made. Where there's a will there's a way.

The longer base of a trapezoid is 8 ft. The longer base of a similar trapezoid is 13 ft. The area of the smaller trapezoid is 240 ft2. What is the area of the larger trapezoid?
Answer:
390 ft²
Step-by-step explanation:
The longer base of a trapezoid is 8 ft. The longer base of a similar trapezoid is 13 ft. The area of the smaller trapezoid is 240 ft² What is the area of the larger trapezoid?
We solve the above question using proportion
(Longer base/Area of trapezoid) smaller trapezoid = (Longer base/Area of trapezoid) bigger trapezoid
Let the the Area of the bigger trapezoid = x
Hence,
= 8ft/240ft = 13ft/x ft
Cross Multiply
8ft × x = 240ft × 13ft
x = 240ft² × 12 ft/8 ft
x = 390 ft²
60% of the animals at a pet shop are dogs. If there are 42 dogs at the shop, then how many animals are there altogether?
25
70
45
50
Answer:
70
Step-by-step explanation:
The formula for this question is
60/100 * x = 42
Look carefully at how this is written. You have so many pets (x) in the shop.
60 % of them are dogs. But that 60% we are told is also how many animals are dogs and that is 42.
So you have two facts meaning the same thing.
Multiply the equation by 100
100 * 60/100 *x = 42 * 100
60x = 4200
Divide by 60
x = 4200/60
x = 70
The total number of animals was 70
