There are 35 boys in band and 49 girls in band. Ryan says that the ratio of 10 poi boys to girls is 5 to 7. Which statement is true?
A He is right because 5 x 7 = 35 and 7 x 7 = 49. Since they are both multiplied by 7, they are equal.
B. He is wrong because the ratio of 5 to 7 is smaller than the ratio 35 to 49.
C. He is right because 35 and 49 are larger numbers than 5 and 7.
D. He is wrong because 35 and 49 are larger numbers than 5 and 7.
Answer:

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 :)

HELP PLEASE ASAPPP !!!!!
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.

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

Hamid has gained weight. He now weights 88kg, which is 10% higher than his normal weight. What is Hamids normal weight
Let his normal weight = 100%
He is 10% more so he is 110%
Divide his weight now by 110% to find his normal weight.
88/1.1 = 80
His normal weight is 80 kg

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]
