Answer:
a) 16 [tex]\frac{2}{3}[/tex] =[tex]\frac{50}{3}[/tex]
b) 1 [tex]\frac{2}{3}[/tex] = [tex]\frac{5}{3}[/tex]
c) [tex]\frac{1}{3}[/tex]
d) 3 [tex]\frac{5}{9}[/tex] = [tex]\frac{32}{9}[/tex]
e) 2 [tex]\frac{1}{9}[/tex] = [tex]\frac{19}{9}[/tex]
Step-by-step explanation:
16.666666 = 16 [tex]\frac{2}{3}[/tex] = (16 * 3) + 2 = [tex]\frac{50}{3}[/tex]
1.6666666 = 1 [tex]\frac{2}{3}[/tex] = (1 * 3) + 2 = [tex]\frac{5}{3}[/tex]
.333333 = [tex]\frac{1}{3}[/tex]
3.55555 = 3 [tex]\frac{5}{9}[/tex] = (3 * 9) + 5 = [tex]\frac{32}{9}[/tex]
2.111111 = 2 [tex]\frac{1}{9}[/tex] = (2 * 9) + 1 = [tex]\frac{19}{9}[/tex]
A common fraction is a numeral which represents a rational number. That same number can also be represented as a decimal, a percent, or with a negative exponent. For example, 0.01, 1%, and 10−2 are all equal to the fraction 1/100. An integer can be thought of as having an implicit denominator of one (for example, 7 equals 7/1).
Other uses for fractions are to represent ratios and division. Thus the fraction 3/4 can also be used to represent the ratio 3:4 (the ratio of the part to the whole), and the division 3÷4 (three divided by four). The non-zero denominator rule, which applies when representing a division as a fraction, is an example of the rule that division by zero is undefined.

The cost y (in dollars) to rent a lane at the bowling alley is proportional to the number x of hours that you rent the lane. It costs $18 to rent the lane for 2 hours.
a) Write an equation that represents the situation
b) Interpret the slope
c)How much does it cost to rent the lane for 3 hours?
Answer:
a) y = 9x
b) For every increase of 1 hour the price to rent the lane increases by $9.
c) $27
Step-by-step explanation:
a) Since it costs $18 for 2 hours we can infer that for every 1 hour it costs $9.
So, the equation would look like this:
y = 9x
b) In this context, for every increase of 1 hour the price to rent the lane increases by $9. Like the question gave us, the price for 2 hours cost $18.
c) Plug 3 into the equation:
y = 9(3)
y = 27
Therefore, it costs $27 to rent the lane for 3 hours.
I hope this helps!!

Consider the lengths of the sides of a triangle as listed. Triangle A: 3, 4, 5 Triangle B: 5, 12, 13 Triangle C: 10, 12, 15 Triangle D: 3, 6, 145 Triangle E: 8, 15, 17 Which of the triangles are NOT right triangles? Select all that apply. Show your work!
Answer:
Triangle E or D
Step-by-step explanation:
Is not the right one
Triangle C and Triangle D are not right angle triangles.
What is right angle triangles?
Right Angle Triangle is a triangle in which one angle is right angle or 90 angle , means in which two sides are perpendicular.
Following length of the sides of triangles are given
Triangle A=3,4,5 , Triangle B=5,12,13 Triangle C= 10,12,15
Triangle D= 3,6,145 and Triangle E=8,15,17
According to Pythagoras theorem , in right angle triangle the square of biggest side is equal to the sum of square of remaining two sides.
So,
The solution for triangle A,
5²=4²+3²
25 = 16 + 9= 25
Triangle A is right angle triangle.
The solution for triangle B,
13²= 5² + 12²
169= 25+144=169
Triangle B is a right angle triangle.
The solution for triangle C,
15²=12²+10²
225= 144+100
225=244
Triangle C is not right angle triangle.
The solution for triangle D,
145²=6²+3²
21025=36+9=45
Triangle D is not a right angle triangle.
The solution for triangle E,
17²=15²+8²
289=225+64=289
Triangle E is right angle triangle.
Therefore, Triangle C and Triangle D are not right angle triangle.

Dan builds identical model cars and sells them online. He records the number of models he completes every couple of hours. The graph shows Dan’s data. Choose two pairs of points on the line and calculate the slopes between them. Is Dan’s productivity constant? Explain.
I'm sorry, I don't know how to put the graph in. BTW, This was on Iready
Answer: you can add the image below this and send the pic then I will anwser it for you.
Step-by-step explanation:
Dan’s productivity is constant as slope of the straight line remains constant.
What is the general equation of a Straight line?The general equation of a straight line is -y = mx + c
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
Other possible equations of line are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have a graph as shown in the image that depicts how many identical cars Dan builds and sells them online.
Let the two points be (2, 3) and (4, 6). Then, the slope will be -
m = (6 - 3)/(4 - 2) = 3/2 = 1.5
Yes, Dan’s productivity is constant as the graph is a straight line and its slope remains constant which depicts Dan's productivity.
Therefore, Dan’s productivity is constant as slope of the straight line remains constant.

F The graph of g(x) is steeper than the graph of f(x).
G The graph of g(x) is less steep than the graph of f(x).
H The graph of g(x) represents a translation of the parent function shifted 2 units up.
J The graph of g(x) represents a translation of the parent function shifted 2 units down
Answer: a
Step-by-step explanation:
The graph of the function g(x) had a horizontal compression of 2 units.
What are some rules for function transformations?Suppose we have a function f(x).
f(x) ± d = Vertical upshift/downshift by d units (x, y ±d).
f(x ± c) = Horizontal left/right shift by c units (x - + c, y).
(a)f(x) = Vertical stretch for a > 0, vertical shrink a < 0. (x, ay).
f(bx) = Horizonatal compression b > 0, horizontal stretch for b < 0. (bx , y).
f(-x) = Reflection over y-axis, (-x, y).
-f(x) = Reflection over x-axis, (x, -y).
Given, A parent function f(x) = x.
Now, The transformed function g(x) = 2x is a horizontal compression of 2 units.
If it was a periodic function it would make the cycle half of the previous cycle or its frequency would have increased.
