Answer:
4. 8(10x-8)
Step-by-step explanation:
An "equivalent expression" has the same value to that of the original expression.
8(10x-8) is an equivalent expression of 80x-64 because both have the same value.Let's solve.
8(10x-8) = 80x-64
8x10x-(8x8) = 80x-64
80x-64 = 80x-64
This makes the answer correct.
Choice 1 is just the same expression, so it's not an equivalent expression.Choice 2 and 3 are not equivalent expressions as well.1 2/5 as a improper friction

  hurry please! 20 points. Find the measure of angle θ. Round your answer to the nearest tenth place.
Answer:
Angle θ would be about 17.1 degrees.
Step-by-step explanation:
To figure out what Angle θ is, first we have to find the hypotenuse. You can easily do that by find the square root of BC² + AC².
c = √4² + 13²
Square 4 and 13 to get 16 and 169 respectively.
c = √16 + 169
Add 16 and 169 to get 185.
c = √185
Find the square root of 185 (I'll round to the nearest tenth.)
c = 13.60147 ≈ 13.6 units
To find angle β, divide AC by AB and find the inverse sine of that.
β = arcsin(13/13.6)
Divide 13 by 13.6. Round to the nearest thousandth.
β = arcsin(0.955)
β ≈ 1.2723 rad
To convert radians to degrees, multiply the radians by 57.2957795 for an approximate amount.
β ≈ (1.2723 * 57.2957795)°
β ≈ 72.8974203 ≈ 72.9 degrees
Now subtract 72.9 from 90 to get angle θ's measure of 17.1 degrees.

Find the slope of the line that passes
through the points (-6, -8) and (-6, 12).
Answer:
there isn't a slope, because this line isn't even a function, because it is a vertical line... so it doesn't pass the vertical line test...
Step-by-step explanation:
Answer:
undefined
Step-by-step explanation:
the equation for the slope of the line is (y2-y1)/(x2-x1)
here are the given points: (-6,-8) and (-6,12)
label the points:
x1=-6
y1=-8
x2=-6
y2=12
now substitute into the equation (m is slope)
m=(12--8)/(-6--6)
m=(12+8)/(-6+6)
m=20/0

There are two bags containing only yellow and orange marbles. Bag A has 9 yellow marbles and 3 orange marbles. Bag B has 7 yellow marbles and 13 orange marbles. A marble is randomly chosen from each bag. List these events from least likely to most likely. Event 1 : choosing a yellow or orange marble from Bag B. Event 2 : choosing a red marble from Bag A. Event 3 : choosing an orange marble from Bag B. Event 4 : choosing a yellow marble from Bag A.
Answer:
Event 2, Event 3, Event 4, Event 1
Step-by-step explanation:
The probability of Event 2 occurring is 0/12(0%) as there are no red marbles in the bag.
The probability of Event 3 occurring is 13/20(65%) as you will get an orange marble from Bag B 13 out of 20 times.
The probability of Event 4 occurring is 9/12(75%) as you will get a yellow marble from Bag A 9 out of 12 times.
The probability of Event 1 occurring is 20/20(100%); therefore you will always get either a yellow or an orange marble from Bag B.

answers: 2n + 3, 3+ 2n
Answer:
2n+3
Step-by-step explanation:
Since the question is asking for "a number" times 2, the first thing that is necessary in any expression is 2n. Next, since there is "3 more", 3 must be added to the 2n. Combining this gives the translation 2n+3.

Answer:
0.53=53/100=53%
Step-by-step explanation:
The decimal equivalent of the unknown percentage is evaluated by moving the decimal 2 places to the left from its current position.

The volume of a conical flask is V cubic centimeters. The height of the flask is the same as its radius. Which function can be used to find the radius of the flask given its volume, the table for f(x) or the graph of g(x)? Explain your answer. If needed, use the graphing tool to arrive at your conclusion.
Answer:
Table for [tex]f(x)[/tex].
Step-by-step explanation:
The table offers a greater accuracy in comparison with graph, since any measure in the latter is subject to a margin of error associated with limitations of human sight, whereas any value can be either used directly from table, or estimated by linear interpolation on the assumption that curve is smooth, guaranteeing lower margins of error.
Answer:
Use an equation to determine whether f(x) or g(x) is the correct model. Create an equation for the radius of the flask in terms of its volume.
Because the height is the same as the radius, write this formula for the volume of the flask:
V= [tex]\frac{1}{3}[/tex][tex]\pi r^{3}[/tex]
Rewrite the formula, solving for r:
[tex]\frac{3V}{\pi } =r^{3}[/tex]
[tex]\sqrt[3]{\frac{3V}{\pi } } =r[/tex]
Now, graph the function and try to identify the values that are in the table.
The graph of the function does match the table of values. So, the table for f(x) can be used to find the radius of the flask. Notice that the graph for g(x) doesn’t match the graph of the formula, so exclude it as the answer.
