Do the ratios 3 8 and 4 7 form a proportion?
Answers
The ratios 3:8 and 4:7 are not proportion. You can tell this easily by how in the second ratio, the first number is one larger, but the second number is 1 lower. If this was proportional, then both numbers would go either up or down depending on the circumstance.

Hooke’s Law of Elasticity states that the force applied, y, varies directly with the distance a spring stretches, x (assuming the spring is not stretched past its elastic limit). If a force of 160 newtons stretches a spring 800 cm, how far will a force of 368 newtons stretch the same spring? Justify your answer.
Group of answer choices
F. It will stretch the same spring 73.6 cm because the equation is y equals 5x.
G. It will stretch the same spring 73.6 cm because the equation is y equals one fifth x..
H. It will stretch the same spring 1,840 cm because the equation is y equals 5x.
J. It will stretch the same spring 1,840 cm because the equation is y equals one fifth x..
Answers
Answer:
H: It will stretch the same spring 1,840 cm because the equation is y equals 5x.
Step-by-step explanation:
800=y
160and368=x
You find the answer by dividing,
⁸⁰⁰⁄₁₆₀= ʸ⁄₃₆₈800 divided by 160 equals 5 which means the equation is y equals 5x
and 368x5=1,840

Rationalize the denominator and simplify. √a+1 - 2 / √a+1 + 2
Answers
Answer:
5+a-4√a+1 / a-3
The rationalization of given expression is a+5-4√(a+1)/(a+5).
What is Rationalization?Rationalization can be considered as the process used to eliminate a radical or an imaginary number from the denominator of an algebraic fraction. That is, remove the radicals in a fraction so that the denominator only contains a rational number.
The given expression is √(a+1)-2/√(a+1)+2.
Multiply both numerator and denominator by (a+1)-2, we get
√(a+1)-2×(a+1)-2/√(a+1)+2×(a+1)-2
= (√(a+1)-2)²/(√(a+1))²+2²
= (√(a+1))²-2×√(a+1)×2+2²/a+1+4
= a+1-4√(a+1)+4/(a+5)
= a+5-4√(a+1)/(a+5)
Therefore, the rationalization of given expression is a+5-4√(a+1)/(a+5).

The formula for the area of a trapezold with altitude k and bases m and n is A=k/2(m+n)
Solve for m.
Answers
Answer:
[tex]m=\frac{2A-kn}{k}[/tex]
Hence, option C is true.
Step-by-step explanation:
Given the expression
[tex]A=\frac{k}{2}\left(m+n\right)[/tex]
Solving for 'm'
[tex]A=\frac{k}{2}\left(m+n\right)[/tex]
Flip the equation
[tex]\frac{k}{2}\left(m+n\right)=A[/tex]
Expanding by applying the distributive law: [tex]a\left(b+c\right)=ab+ac[/tex]
[tex]\frac{1}{2}km+\frac{1}{2}kn=A[/tex]
Add (-1)/2 × kn to both sides
[tex]\frac{1}{2}km+\frac{1}{2}kn+\left(-\frac{1}{2}kn\right)=\left(-\frac{1}{2}kn\right)+A[/tex]
simplify
[tex]\frac{1}{2}km=-\frac{1}{2}kn+A[/tex]
Divide both sides by k/2
[tex]\frac{\frac{1}{2}km}{\frac{k}{2}}=\frac{-\frac{1}{2}kn+A}{\frac{k}{2}}[/tex]
[tex]m=\frac{2A-kn}{k}[/tex]
Therefore,
[tex]m=\frac{2A-kn}{k}[/tex]
Hence, option C is true.

Answer:
blue point value is -10
Step-by-step explanation:
First lets find the difference between each point on the line,
The gap between 10 and 2 has 2 points
So 10 - 2 = 8 is the difference in value between point A(10) and point C(2), but we need to find difference between each point,
So 8/2 = 4 is the difference between each point from top to bottom.
There is 3 points after 2 to reach blue,
So 4 x 3 = 12, is the difference in value between point C(2) and point blue,
So, subtracting 12 from 2 will get us the value of blue, 2 - 12 = -10
Therefore the value of blue point is -10

Which list of fractions is in order from smallest to largest? 1/6,1/3 ,1/2 ,1/2 ,1/3 ,1/6 ,1/6 ,1/2 ,1/3, 1/2, 1/6, 1/3
Answers
Answer:
The smallest order of fractions in that order would be,
Step-by-step explanation:
1/6, 1/3, 1/2
because the bigger the denominater, the larger the whole is, and in 1/2, it would be equivalent to half, but 1/6 would be smaller. Let's say if it were 3/6, it would be equivalent to 1/2 because its half right? so thats another way you can tell how one fraction is smaller than another.
1/6,1/3,1/2 is the list of fractions is in order from smallest to largest.
What is Fraction?A fraction represents a part of a whole.
The given three fractions are 1/6, 1/3 and 1/2.
We need to order them smallest to largest.
Let us make the denominator same for all the three fractions to compare which is larger and smaller.
1/6×2/2=2/12
1/3×4/4=4/12
1/2×6/6=6/12
So 1/6 is smaller, 1/2 is bigger.
We know Arranging numbers in increasing order, that is, from smallest to largest is known as ascending order.
by using ascending order we can order the fractions like 1/6,1/3,1/2.
Hence, 1/6,1/3,1/2 is the list of fractions is in order from smallest to largest.

Answers
Answer:
5
Step-by-step explanation:
The constant of proportionality (r) in the equation y=rx is 3
How to determine the constant of proportionality?The equation of the function is given as:
y = rx
Make r the subject
r = y/x
From the table, we have:
y = 36 when x = 12
So, the equation becomes
r = 36/12
Divide
r = 3
Hence, the constant of proportionality (r) in the equation y=rx is 3
