Which ratio is equivalent to the unit rate 30miles/1gallon? Explain how the unit rate is transformed into the equivalent ratio.
Responses
A 3gallons/10miles; by dividing the numerator and denominator of the unit rate by 10.3 gallons 10 miles ; by dividing the numerator and denominator of the unit rate by 10.
B 90miles/5gallons; by multiplying the numerator and denominator of the unit rate by 3.90 miles 5 gallons ; by multiplying the numerator and denominator of the unit rate by 3.
C 180miles/6gallons; by multiplying the numerator and denominator of the unit rate by 6.180 miles 6 gallons ; by multiplying the numerator and denominator of the unit rate by 6.
D 6gallons/180miles; by multiplying the numerator and denominator of the unit rate by 2.
Answer:
C
Step-by-step explanation:
If you divide 180 divided by 30, it will be 6, and 6 divided by 1 is 6.
30 x 6 = 180
1 x 6 = 180
30/1 = 180/6

The Whittman family took a car trip. They traveled 1/5 the distance from San Antonio to Austin on Monday and 2/9 the distance on Tuesday. What fraction of the distance between San Antonio and Austin did the Whittman family travel on Monday and Tuesday?
Answer: 19/45
Step-by-step explanation:
1/5 + 2/9 = ?
Find the least common denominator.
which in this case is 45
5 times 9 = 45
Multiply 1/5 by 9/9
Multiply 2/9 by 5/5
9/45 + 10/45= 19/45

The purchase price of a camcorder is $588. What is the total price if the sales tax rate is 4.5%?
Hello,
The sales tax for a camcorder that costs $588 would be $588 * 0.045 = $26.46. Therefore, the total price would be $588 + $26.46 = $614.46.
The answer is: $614.46

A. Draw a ray
B. Connect the arrows with a straight line
C. Line up the baseline on the protractor with the ray
D. Draw arrows on both ends to make them rays
Answer:

What is the asymptote of the graph of an exponential growth or exponential decay function? Explain your reasoning.
Let's consider an exponential decay function.
As an example, let's look at [tex]f(\text{x}) = 100(0.5)^{\text{x}}[/tex]
Here is a table of selected values:
[tex]\begin{array}{|c|c|} \cline{1-2}\text{x} & \text{f(x)}\\\cline{1-2}0 & 100\\\cline{1-2}1 & 50\\\cline{1-2}2 & 25\\\cline{1-2}3 & 12.5\\\cline{1-2}4 & 6.25\\\cline{1-2}5 & 3.125\\\cline{1-2}6 & 1.5625\\\cline{1-2}\end{array}[/tex]
As x gets bigger, y = f(x) is slowly approaching y = 0. It will never get to this exact value because we keep taking half of the previous y value (eg: we go from y = 25 to y = 12.5); there's no way to arrive at zero through this continuous halving process. If x/2 = 0, then x itself must be 0. But we started off with a nonzero value.
Visually, the curve is slowly approaching the x-axis. We say that the horizontal asymptote is y = 0 which is directly overlapping the x-axis. Think of the asymptote as an electric fence you can get closer to but not actually touch.
See the graph below. I used Desmos to create the graph.
7/9 multiplied by 4/7 in simplest form
4/9 or it would be 0.444444 and so on but the answer is 4/9
Can someone help, please
Answer:
y = 2x + 4/5
Step-by-step explanation:
Slope-intercept form is written as:
y = mx + b, where (x,y) is a point on the line, m is the slope, and b is the y-intercept.
To get 10x - 5y = -4 into the form y = mx + b, you'll first want to get y by itself. You can start by subtracting 10x from both sides.
10x - 5y = -4
-5y = -10x - 4
As you can see, y still has a coefficient of -5 in front of it, so we'll have to divide the entire equation by -5 (you have to divide each term individually).
-5y = -10x - 4
y = 2x + 4/5

Describe how you could use a graphing calculator to estimate the value of x when f(x) = 8(1.25)^x equals 15.
Answer: here
Step-by-step explanation:
8 (1.25) x = 15 8(1.25)^x=15 8 (1.25) x = 15. There are two ways: by using a graph or by using a table. Here, I will use a graph since using a table was already discussed
Using a graphing calculator the value of x is sought by tracing from point 15 up to the curve, at the point of intersection with the curve then trace to the corresponding y direction. At 15 the f(x) is about 227
What is exponential graph?A curve that depicts an exponential function is known as an exponential graph.
The curve have a horizontal asymptote and either an increasing slope or a decreasing slope. this is to say that the curve begins as a horizontal line, increases or drops gradually, and then the growth or decay accelerates. It may or may not cut the x-axis, but it always cuts the y-axis at some point.
An exponential graph will almost always have a y-intercept but not necessarily an x-intercept.
How to read graph of exponential functionsThe corresponding value of each point is located by tracing it using imaginary line
From the x axis at 15 draw an imaginary line up to the curve. the point of intersection of the line and the curve is traced to the y axis. The value at that point gives the required the solution
The graph is attached
