Answer:
52.5
Step-by-step explanation:
You would use the Pythagorean theorem to solve this. Using the formula,
a^2 + b^2 = ^2
You would have an equation of 50^2 + 16^2 = c ^2.
50^2 is 2500, and 16^2 is 256.
There, you have 2500+256 = c^2
add those together, and you have 2756.
Now, you have to find the square root of 2756 (to solve 2756 = c^2)
which leaves you with 52.4976189936 . Rounded to the nearest tenth, you end up with 52.5.

Answer:
A
Step-by-step explanation:
the bottom ones don't make sense, and b says if she heals then she WONT play
through (2, -4) and parallel to y= 9/2x+3
Answer:
y=[tex]\frac{9}{2\\}[/tex] x-13
Step-by-step explanation:
first, since it's parallel the slope has to be the same and the y-intercept has to be different.
you will have y=9/2x+b
find b, by using the points you are given so you will get
-4=(9/2) times (2)+b.
then when sloving you will get b=-13 and so the full equation will be
y=9/2x-13

The scatter plot shows the relationship between years of experience and hourly pay at one factory.
describe the relationship between experience and pay years of work
Answer:
I'm pretty sure it's B.
Step-by-step explanation:
The more experience you have, the better you are at your job. If your doing better at your job, you get better pay.
Good luck on the test BTW. =)
The correct answer is option B which is the hourly pay usually increases with the work experience.
What is a scatter plot?Scatter plots are graphs that show how two variables in a data collection relate to one another. On a two-dimensional plane or in a Cartesian system, it represents data points.
In the given graph horizontal axis contains the years of experience and the vertical axis consists of the hourly pay of an employee. We can see that the employees with higher experience are paid a higher hourly amount.
Therefore the correct answer is option B which is the hourly pay usually increases with the work experience.

Answer:
wouldn't they both be 88
I'm not sure if that's correct though
Answer:
x = 88
y = 88
Step-by-step explanation:
66 + 26 + x = 180 (collect like terms)
92 + x = 180 (subtract 92 on both sides)
x = 88
y = x
y = 88
They are vertical so their measures are the same.

work out the area of this semi circle
Answer:
39.27
Step-by-step explanation:
The area of a semi-circle is pi times the radius squared divided by 2. So basically standard area of a circle formula (pi times the radius squared) but then you add in the extra step of dividing it by 2.
The formula looks like this:
π × r² ÷ 2
The radius is half the diameter of the circle. So basically think of it as a line to the middle of the circle. Our diameter is 10, (the diameter is the entire length of the circle. It gives us this already. If you need diameter and only have the radius add the radius together twice or multiply it by 2 to get the diameter. Fun fact..?)
and it tells us to substitute pi for 3.142.
So, plugging our numbers in we get:
3.142 x 5^2 ÷ 2 = 39.275.
Cut out the 3rd decimal place (5) as it tells us to only include the first 2 decimal places, and we finally end up with 39.27.
Hope this helps and have a nice day!
in a bag there are 10 balls numbered 1 to 10 A ball is picked at random find the probability of picking the following
(a) number 7
(b) an odd number
(c) an even number
(d) an prime number
Answer:
a) 1/10
b) 1/2
c) 1/2
d) 2/5
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = Total event/Total sample space
Since there are ten ball in the bag numbered 1 to 10
S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
n(S) = 10
Total sample space = 10
a) If we are to get the probability of picking the number 7.
(E) = {7}
n(E) = 1
Event = 1
Pr(picking 7) = 1/10
b) a) If we are to get the probability of picking an odd number
(E) = {1, 3, 5, 7 , 9}
n(E) = 5
Event = 5
Pr(an odd number) = 5/10 = 1/2
c) a) If we are to get the probability of picking an even number
(E) = {2, 4, 6, 8,10}
n(E) = 5
Event = 5
Pr(an even number) = 5/10 = 1/2
d) a) If we are to get the probability of picking prime
(E) = {2, 3, 5, 7}
n(E) = 4
Event = 4
Pr(prime) = 4/10 = 2/5

Which function has an inverse that is a function?
b(x) = x2 + 3
d(x) = –9
m(x) = –7x
p(x) = |x|
Answer:
All but the second one
Step-by-step explanation:
Find the inverse of each function:
b(x)=x^2+3
y=x^2+3
x=y^2+3
x-3=y^2
sqrt(x-3)=y
This inverse function is a function
d(x)=-9
y=-9
This doesn't have an inverse function
m(x)=-7x
y=-7x
x=-7y
-1/7x=y
This inverse function is a function
p(x)=|x|
y=|x|
x=|y|
x=y
This inverse function is a function
Therefore, all but the second function have inverses that are functions
Answer:
All but the second one have inverse functions

Ramiro se dedica a circular terrenos se le presenta un trabajo se circular un terreno cuadrado con una superficie de 470 metro cuadrados y le piden que lo circulen con 4 hilos de alambre de puas sobre postes. ¿cuantos metros lineales con alambre de puas nesecita?
Answer:
346.88 meters
Step-by-step explanation:
Given that the area of the square-shaped terrain is 470 square meters.
Let a be the side of the terrain, so
Area of the square-shaped terrain, [tex]a^2=470[/tex] square meters.
Therefore, the length of one side, [tex]a=\sqrt {470}=21.68[/tex] meters.
The length of single thread wire required in circulating the square-shaped terrain = the perimeter of the square-shaped terrain
As the perimeter of a square having side a = 4a
So, the length of single thread wire required in circulating the square-shaped terrain= 4 x 21.68 =86.72 meters
Therefore, the length of 4 thread wire required in circulating the square-shaped terrain= 4 x 86.72=346.88 meters.
