This is the same as the slope because this is a linear equation
y = 5x is the same as y = 5x+0 which compares to y = mx+b
m = 5 is the slope = rate of change
b = 0 is the y intercept = starting amount
Emma conducted an experiment in which she rolled a
six-sided, fair number cube 300 times. How many times
would you predict she rolled a 6?
Answer:
50
Step-by-step explanation:
A six-sided fair number cube has numbers 1, 2, 3, 4, 5, and 6 on each side.
so, 300/6= 50
For each number it is predicted that it will roll 50 times.
Answer:
Sample Response: A number cube has six sides. The probability of landing on any of the numbers is equal. The theoretical probability of rolling a 6 is 1/6. I expect a 6 to be rolled (1/6)(300), or 50 of 300 times.

Answer:
Option D or 3
Step-by-step explanation:
It says so on edge 2020. I thought it was option c, but it is D. Can anyone tell me whyyyyyy.
The solution is, the scale factor of this dilation is option D. 3.
What is scale factor?A scale factor is when you enlarge a shape and each side is multiplied by the same number. This number is called the scale factor. Maps use scale factors to represent the distance between two places accurately.
here, we have,
given that,
Line segments X Y and X prime Y prime.
From the point of dilation, the distance to point Y is 3 and the distance to point X is 2.
The distance from point Y to Y prime is 6, and the distance from X to X prime is 4.
Hence, The solution is, the scale factor of this dilation is option D. 3.

if the 897 step stairwell has 50 landings, how many steps would be between landings
Answer:
17.94
I think you would do 897 divided by 50. Tell me if im wrong.
To find the number of steps between each landing in an 897-step stairwell with 50 landings, divide the total steps by the number of segments, resulting in approximately 17 to 18 steps per segment.
Step by Step Solution:
To determine how many steps are between each landing in an 897-step stairwell with 50 landings, follow these steps:
First, note that there are 50 landings, which divide the stairwell into 51 segments (since the top step is considered the last segment).Then, divide the total number of steps by the number of segments: 897 steps / 51 segments = 17.588 steps per segment.Since you can't have a fraction of a step, you may need to adjust for some rounding. Usually, some segments may have 17 steps and others may have 18 steps to total correctly.Therefore, each segment will have approximately 17 or 18 steps.

Identify given.
[Ralph's Walking Distance Function]: d = -6t + 10
[Joan's Bicycle Distance Function]: d = 14t
Step 2: Find Meeting Point
To find where Joan and Ralph will meet, we need to find where they intersect. Therefore, we need to find the time which they both meet up at. To do this, we can use the process of substitution to find our value of t:
[Equation 1] Substitute in d:From here, we can simply use techniques listed under "Algebra I" to solve for t:
[tex]\displaystyle\begin{aligned}14t & = -6t + 10 \\20t & = 10 \\t & = \boxed{ \frac{1}{2} } \\\end{aligned}[/tex]
∴ both Joan and Ralph will meet up in half an hour, or 0.5 hours.
Step 3: Find Mileage
To find how many miles they will meet up at, we substitute the number of hours elapsed (found in Step 2) and substitute it into any of the equations given:
[tex]\displaystyle\begin{aligned}d & = 14t \\& = 14 \bigg( \frac{1}{2} \bigg) \\& = \boxed{7} \\\end{aligned}[/tex]
∴ Joan will meet Ralph after 7 miles.

Topic: Algebra I
The answer is B. 7 miles. Joan and Ralph meet when their distances are equal. By solving the distance equations, we find they meet after 7 miles.
To establish where Joan will meet Ralph, we must find the time when their distances are equal. We equate their distance equations: d = -6t + 10 (Ralph) and d = 14t (Joan).
Set the equations equal to each other:
-6t + 10 = 14tCombine like terms:
10 = 14t + 6t10 = 20tDivide both sides by 20:
t = 0.5Next, we substitute t = 0.5 into either of the original equations to find the distance:
Using Joan's equation: d = 14t
d = 14(0.5)d = 7So, the distance at which Joan meets Ralph is 7 miles.
Therefore, the correct answer is B. 7 miles.

Over what interval is the graph of
y = |x + 2] increasing?
Over (-2, ∞) the graph of function y = | x + 2| is increasing.
Given that,
To determine over what interval the graph of y = |x + 2] increases.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
y = | x + 2|
Since from (∞, -2), the graph is decreasing, but at -2 the graph has zero ordinate and afterward, the graph starts increasing. So, over (-2, ∞) the graph of function y = | x + 2| is increasing.
Thus, over (-2, ∞) the graph of function y = | x + 2| is increasing.

A rectangular picture frame has a perimeter of 54 inches. The height of the frame is 14 inches. What is the width of the frame?

What is perimeter of rectangle?The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.
Perimeter of the rectangle = 2(length+width)
Given the parameters are;
Rectangular picture frame has a perimeter of 54 inches. The height of the frame is 14 inches.
Perimeter of the rectangle = 2(length+width)
Perimeter = 2( 14 + w )
2( 14 + w ) = 54
Solving;
28 + 2w = 54
2w = 54 - 28
2w = 26
w = 13
To know more about perimeter of rectangle refer to :

#SPJ6
The width of the frame is 13 inches.
To find the width of a rectangular picture frame when the perimeter is 54 inches and the height is 14 inches, we start by understanding the formula for perimeter of a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length (or height), and w is the width. In this case, we are given that the perimeter (P) is 54 inches and one dimension (the height/length, l) is 14 inches.
Substitute the known values into the perimeter formula to get 54 = 2(14) + 2w. Simplify the equation by first multiplying 2 by 14, which gives 54 = 28 + 2w. To isolate w, subtract 28 from both sides of the equation: 26 = 2w. Finally, divide both sides by 2 to find the width: w = 13 inches.
The solution is 54 = 2(14) + 2w = 28 + 2w. The width of the frame is 13 inches.
You take out a loan for $523 at an interest rate of 9% for five years. What is the total amount
that you will have at the end of the five years?
Final answer:
To find the total amount due after five years on a loan of $523 with a 9% interest rate, first calculate the simple interest ($235.35) and then add it to the principal to get a total of $758.35.
Explanation:
To calculate the total amount you will have at the end of five years after taking out a loan for $523 at an interest rate of 9%, you need to use the formula for calculating the future value with simple interest: Principal + (principal × rate × time). The principal in this case is $523, the rate is 0.09 (9% expressed as a decimal), and the time is 5 years.
First, we calculate the simple interest: Interest = Principal × rate × time = $523 × 0.09 × 5. This gives us the total interest that will be charged over the five years.
Step 2. Calculate the simple interest: $523 × 0.09 × 5 = $235.35.
Step 3. Calculate the total future amount using the formula: Principal + Interest = $523 + $235.35 = $758.35.
Therefore, the total amount that you will have to pay at the end of the five years is $758.35.
