Find the value of X and Y
Answer:
y=60 degrees ; x=120 degrees.
Step-by-step explanation:
All triangles' angles must add up to 180 degrees. An equilateral triangle has 3 equal sides and degrees. If it gives the angle of one all the other angles are the same. For x you see the parallel line below it with the line to the left going through with the same angle as the one below. The angles are the same and if it is labeled in one then it is the same in the other.

Answer:
The mean is 19.
Step-by-step explanation:
To find the mean, you add up all of the numbers then divide by how many numbers there are. So you would do 3+8+10+11+14+17+22+24+25+35+40, then divide it by 9 since there are 9 numbers shown, which gets you to 19.

A book contains the following recommend weight for kangaroos:" Give the kangaroo 120 pounds for the first 5 feet plus 5 pounds for every inch over 5 feet tall." Using this description, what height corresponds to the recommended weight of 180 pounds?
Answer:
A 180-pound kangaroo's recommended height is 6 feet.
Step-by-step explanation:
Since 120-pound kangaroo is 5 feet tall and for every inch over this height we add 5 pounds to the total weight, we can make this formula. [tex]120+x=180[/tex]. Using this we can figure out the weight difference between a 120-pound kangaroo and a 180-pound kangaroo. After solving for x we get [tex]x=60[/tex].
Now that we know the 180-pound kangaroo weighs 60 more pounds than a 120-pound kangaroo we can divide that weight difference by 5 to figure out the height difference. [tex]60/5=12[/tex]
After getting the height difference from the weight difference we can conclude that a 180-pound kangaroo's recommended height is 5 feet and 12 inches. Since 12 inches = 1 foot we can easily convert 5' 12" to 6'. This means that a 180-pound kangaroo is 6 feet tall.

Answer:

Step-by-step explanation:
$187 for 11 hrs
$119 for x hrs
write a proportion.
187/11 = 119/x since Reuben is making money at the same rate.
solve for x:
187x = 1309
x=7
7 hours
Answer:
7 hours
Step-by-step explanation:
Reuben works for 11 hours to earn $187
This means, his earnings rate is $187 per 11 hours of work
In 1 hour he would earn = 187/ 11 = $17
Therefore, he earns $17 in 1 hour
To find out how many hours he has to work to make $119, we multiply this by the rate.
He will earn $119 in = $119 x (1 hour/ $17) = 7 hours
Reuben has to work 7 hours to make $119

What is the exact value of cos 3pi/4
Answer:
cos(3π/4) = -√2/2
Step-by-step explanation:
According to the unit circle, the exact value of cos(3π/4) is -√2/2.
The exact value of cos 3π/4 is - 1/√2
Here we have to find the exact value of
cos 3π/4
Since we know that,
The values of all trigonometric functions depending on the ratio of sides of a right-angled triangle are defined as trigonometric ratios. The trigonometric ratios of any acute angle are the ratios of the sides of a right-angled triangle with respect to that acute angle.
We can write,
cos 3π/4 = cos(π/2 + π/4)
Since we know that,
cos(π/2 + θ) = - sin θ
Therefore,
⇒ cos(π/2 + π/4) = - sin π/4
= - 1/√2
Hence,
⇒ cos 3π/4 = - 1/√2

The number of surface flaws in plastic panels used in the interior of automobiles has a Poisson distribution with a mean of 0.03 flaws per square foot of plastic panel. Assume an automobile interior contains 10 square feet of plastic panel. (a) What is the probability that there are no surface flaws in an auto's interior
Answer:
0.7408 = 74.08% probability that there are no surface flaws in an auto's interior.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
In which
x is the number of successes
e = 2.71828 is the Euler number
[tex]\mu[/tex] is the mean in the given interval.
Mean of 0.03 flaws per square foot of plastic panel.
This means that [tex]\mu = 0.03n[/tex], in which n is the number of square feet.
Assume an automobile interior contains 10 square feet of plastic panel.
This means that [tex]n = 10[/tex], so [tex]\mu = 0.03(10) = 0.3[/tex]
What is the probability that there are no surface flaws in an auto's interior?
This is [tex]P(X = 0)[/tex]. So
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
[tex]P(X = x) = \frac{e^{-0.3}*(0.3)^{0}}{(0)!} = 0.7408[/tex]
0.7408 = 74.08% probability that there are no surface flaws in an auto's interior.

[tex](x,y) = (1,5)[/tex] --- pass through
Required
The radius (r)
The equation of circle is:
[tex](x - h)^2 + (y - k)^2 = r^2[/tex]
So, we have:
[tex](1 - -3)^2 + (5 - 2)^2 = r^2[/tex]
[tex](4)^2 + (3)^2 = r^2[/tex]
[tex]16+9 = r^2[/tex]
[tex]25 = r^2[/tex]

there are 13 cards per 4 suits, totalling 52 cards in an entire deck
13 represents an entire 1 suit out of 52 cards
13/52 = 0.25

A farmer wants to make a rectangular field with a total area of 3200^2. It is surrounded by a fence. It is divided into 3 equal areas by fences. What is the shortest total length of fence with which this can be done?
Answer:
18133.333... units
Step-by-step explanation:
the shortest circumference for a given area based on rectangles is a square (all sides of equal length).
we cannot split a square completely into 3 equal area squares (only 4).
the best approach is then to split this main square into 3 equal area rectangles (not equal rectangles).
area of square 3200² = 10240000
a third of that area is 3413333.333...
now, splitting the main square into 3 equal "strips" of land creates 3 narrow and long rectangles, which is bad for minimizing the circumference. the best solution is to get as closely as possible to a square shape.
that we get by splitting one side in half and go in as far as the land area allows, which would be
half a side = 1600
3413333.33.../1600 = 2133.33...
so, we get 2 areas of 1600 × 2133.33...
and one area of (3200-2133.33...)×3200 = 1066.66...×3200
the length of fence needed is then
around the main square = 4×3200 = 12800
plus one length of fence between the first 2 parts : 2133.33...
plus one intensive long side between the first 2 parts and the remaining third part : 3200
in total : 18133.33...
to check : the three slices would require the 12800 plus 2 long lines inside between the 3 slices : 2×3200
in total : 19200
and an attempt to simply build one long strip of 3 equal area squares next to each other :
the side length of one such square is
sqrt(341333.33...) = 1847.520861...
as fence we would need 6 times that side length for the top and the bottom of the long strip, 2 times that side length for the sides left and right if the strip, and 2 times inside as additional delimiters between the 3 squares.
in total : (6+2+2) × 1847.520861... = 10×1847.520861...
= 18475.20861...
this is all larger than the original solution.
