Given: triangle NOP is similar to triangle WXY
We know that NOP has a base length of 4 while triangle WXY has a base length of 10
10 / 4 = 2.5
The scale factor = 2.5
We also know that all similar triangles have congruent angles
The measure of angle X on triangle WXY = 58 degrees because its corresponding angle on triangle NOP = 58 degrees.
We know that all the angles of a triangle add up to 180.
The measure of angle P for triangle NOP is:
180 - (49 + 58) = 73 degrees. This means that the measure of angle Y for triangle WXY is also 73 degrees.
We know that the scale factor = 2.5 so 12 / 2.5 = 4.8
NP / WY = 12 / 4.8 = 2.5
The length of WX = 6 * 2.5 = 15
The length of NP = WY / 2.5 = 12 / 2.5 = 4.8
The scale factor of triangle NOP to triangle WXY is 2/5 =0.4.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
Given that, ΔNOP∼ΔWXY
NO/WX =OP/XY =NP/WY
6/WX =4/10 =NP/12
a) The scale factor is 4/10 =2/5
b) m∠X=58
c) m∠Y=
m∠N+m∠O+m∠P
=49°+58°+m∠P=180°
107°+m∠P=180°
m∠P=73°
So, m∠Y=73°
d. 6/WX =4/10 =NP/12
4/10 =NP/12
2/5=NP/12
NP=24/5
NP=4.8
So, NP/WY =4.8/12
e) WX
6/WX =4/10
60=4WX
WX=60/4
WX=15
f) NP
4/10 =NP/12
2/5=NP/12
NP=24/5
NP=4.8
Therefore, the scale factor of triangle NOP to triangle WXY is 2/5 =0.4.

The graph which represent the function f ( x ) = 4 [ x ] is graph B
What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = 4 [ x ]
And , function f(x) = 4[x] represents the greatest integer function, which returns the largest integer less than or equal to x
The graph of the greatest integer function consists of horizontal segments, with jumps at the integers. Since the function is multiplied by 4 in this case, the distance between the jumps will be 1/4 of the original distance.
Hence , the graph is Option B

If Thor's hammer can travel 4.95 km per second, how far can it travel in 12 seconds?
Answer:
59.4 km
Step-by-step explanation:
use the formula distance = velocity x time
where velocity = 4.95 km/sec
time = 12 sec
plugin values into the formula
distance = 4.95 km/sec x 12 sec
distance = 59.4 km
therefore,
thor's hammer travelled 59.4 km

6) Order the fractions and decimals from least to greatest 0.75, 1/2, 04, 1/5
Answer:
Order from least to greatest: 1/5, 0.75, 1/2, 04.
Explanation:
1/5 is the least because 0.75 is equivalent to 1/4 and 1/2 is greater than both of those. 04 is a whole number because the 0 doesn't matter if there's no decimal point, which there isn't. So take away the 0 and you get the whole number 4! Hope this helped :)
Twin brothers, Billy and Bobby, can mow their grandparent’s lawn together in 63 minutes. Billy could mow the lawn by himself in 25 minutes less time that it would take Bobby. How long would it take Bobby to mow the lawn by himself? I’ve tried multiple problems like this but I keep getting them wrong, please help.
Answer:
140 minutesStep-by-step explanation:
this problem focuses on the combined work rate
both can finish the work under 63 minute
let bobby mow the lawn in x minute
Billy will then mow the lawn in x-25 minutes
Let the completed job = 1 (a mowed lawn)
we can now apply the combined work formula for the two boys as
[tex]\frac{63}{x}+\frac{63}{x-25}=1[/tex]
multiplying through by x(x-25 )we have
[tex]63(x-25)+63x= x(x-25)[/tex]
open bracket we have
[tex]63x-1575+63x= x^2-25x[/tex]
rearranging and collecting like terms we have
[tex]0=x^2-25x-63x-63x+1575 \\\\0=x^2-151x+1575 \\\\x^2-151x+1575=0[/tex]
we can now use the quadractic formula
[tex]x=\frac{-b\frac{+}{} \sqrt{b^2-4ac} }{2a}[/tex]
a= 1
b= -151
c= 1575
[tex]x=\frac{-(-151)\frac{+}{} \sqrt{151^2-4*1*1575} }{2*1}[/tex]
[tex]x=\frac{-(-151)\frac{+}{} \sqrt{22801-6300} }{2} \\\\x=\frac{-(-151)\frac{+}{} \sqrt{16501} }{2} \\\\x=\frac{-(-151)\frac{+}{} 128.45}{2} \\\\[/tex]
[tex]x=\frac{-(-151)+128.45}{2} \\\\\x=\frac{279.45}{2} \\\\x=139.72 \\\\\\x=\frac{-(-151)-128.45}{2}\\\\x=\frac{151-128.45}{2}\\\\x=\frac{22.55}{2}\\\\x=11.27[/tex]
the first answer x= 139.72 approximately 140 minutes mins is correct for Bobby's time
let us check
[tex]\frac{63}{140}+\frac{63}{140-25}=1\\\\\\0.45+\frac{63}{115} =1\\\\0.45+0.5478=1\\0.997 =1[/tex]
we can see that the solution approximates to 1

Answer:
1. Statisticians and operations research analysts.
2. 167,582.3 persons.
3. 40%.
4. Pharmacist
Step-by-step explanation:
1. According to data from the U.S. Bureau of Labor Statistics, Statisticians and Operations Research analysts are among the fastest-growing occupations in terms of their percent growth, having high projected growth rates of 33.8 percent and 30.2 percent.
2. People who are expected to work as Mathematicians by 2026 are projected to grow up to 27.9 percent (167,582.3 persons).
3. About 40% of the fastest-growing careers are in the health & human services industry. This is the case because as the human population continues to increase, the need for healthcare providers will increase rapidly.
4. Considering the lower projection of 22% for this career, it gives better prospects for getting employment due to the limited supply of Pharmacists.
