Answer:
Step-by-step explanation:
v=d/t, t=d/v, since t=t
1225/(v+w)=1100/(v-w)
1225v-1225w=1100v+1100w
2325w=125v
w=125v/2325, given v=575
w=125(575)/2325
w=30.91 mph

You want to factor out perfect squares if they exist.
[tex]1.\ \sqrt{36}=\sqrt{6^2}=6\\ \\ 2.\ \sqrt{40}=\sqrt{2^2(10)}=2\sqrt{10}\\ \\ 3.\ \sqrt{75}=\sqrt{3(5^2)}=5\sqrt{3}\\ \\ 4.\ \sqrt{120}=\sqrt{2^2(30)}=2\sqrt{30}\\ \\ 5.\ \sqrt{84}=\sqrt{2^2(21)}=2\sqrt{21}\\ \\ 6.\ \sqrt{48}=\sqrt{4^2(3)}=4\sqrt{3}[/tex]
Combine the like terms to simplify x + 4 - 5x - 2
Answer:
-1
Step-by-step explanation:
what you would start by doing is subtract x from 5 which gives it -6x. then, you would add the 2 to the 4 which cancels out the negative 2. so it should look like 6=-6x, then you would divide 6 by -6 which gives your answer as -1

Answer:
108m²
Step-by-step explanation:
So we know to find the volume for a rectangular prism we need to multiply base * height * leght.
For this problem to make it a little easier we can seperate it into 2 rectangular prisms. and then add the volume of both after.
1st prism volume:
2 * 2 * 7 = 28cm²
2st prism volume:
5 * 2 * 8 = 80m²
Final prism volume:
28cm² + 80m² = 108m²

the graph shows the relationship between the hours rachel studied and the exam grades she earned
Plz answer
Answer:
11. This is a function because every input, the number of hours studied, has one output, the grade.
12. Looking at the graph it already has a point for 2 hours. Plotting another 2 hour point would no longer make it a function. This is because there are now two outputs for one input.
Step-by-step explanation:
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
The given relationship is a function by vertical line test and by plotting the grade for 2 hours will remove the function.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
Given the graph,
If we apply the vertical line test it means we will draw vertical lines at every plotted point.
For me, in this function, the number of points on every line must be 1.
Since in the graph for each input only one output so it is a function.
Now if we plot the grade for 2 hours the number of grades for 2 hours will be 2 so it will remove the function because it gives two outputs unless it is not the same point it's that's 70.
Hence "The given relationship is a function by vertical line test and by plotting the grade for 2 hours will remove the function".

A ceiling fan has 13-centimeter blades (so the radius of the circular fan is 13 centimeters). Suppose the fan turns at a rate of 58 revolutions per minute.
(a) Find the angular speed of the fan in radians per minute.
(b) Find the linear speed of the tip of a blade in centimeters per minute,
Do not round any intermediate computations, and round your answer to the nearest whole number
Answer:
A ceiling fan has 13-inch blades (so the radius of the circular fan is 13 inches). Suppose the linear speed of the tip of a blade is 8 feet per second
help! is this correct?
Answer:
D) 13
Step-by-step explanation:
I'm going to assume 120 is a vertical angle so:
x + 47 + 120 = 180
x + 167 = 180
x = 180 - 167
x = 13

Find DE (trigonometry)
Show work pls
Answer:
Step-by-step explanation:
tan61=FD/24
FD=24tan61
tan19=DE/FD
DE=FDtan19, since FD=24tan61
DE=(24tan61)(tan19) (exact)
DE=14.9 units (rounded to nearst tenth)
Though they might round to 15 units...

The two angles below are complementary angles. Find the value of a.
Answer: a = 43°
Step-by-step explanation: If two angles are complementary,
then the sum of their measures is 90 degrees.
So we can setup the equation 47 + a = 90.
Now subtract 47 from both sides to get a = 43°.
