Show how to add 2 1/2+ 4/5 using the number line below
Answer:
Start at 2 1/2 plot that. Then go to 3 3/10 which is 3 right of the whole number 3 and plot it. Lastly, draw lines or bumps to represent going from 2 1/2 to 3 3/10.
Step-by-step explanation:
The Simplest way (This includes the graphing part but I advise you to use the addition steps first)
I always like to convert mixed numbers into decimals.
2 1/2 is 2.5 and 4/5 is 0.8.
2.5 + 0.8 = 3.3 which is 3 3/10
Graph:
2 1/2 should be in the middle of the whole numbers 2 and 3.
That is your starting point.
Now to add 4/5 which is 0.8 you could do 2.5 + 0.8 = 3.3
You need to find your ending point.
Your ending point should be 3 tickmarks to the right of 3.
Now, you could draw hop marks or arrows starting from 2 1/2 to 4/5
Addition Steps:
First, convert 2 1/2 to an improper fraction.
2x2 + 1 = numerator.
4+1 = 5
5/2 is 2 1/2.
Now you need to find a common denominator for 2 and 5.
This should be 10.
Multiply 5/2 by 5/5
Multiply 4/5 by 2/2
25/10 and 8/10 should be the answers
Now do 25+8 but keep the denominator 10.
25+8 is 33/10.
You could convert it to 3.3 which is 3 3/10
3 3/10 is on your number line.

Mrs. Ruiz bought 5 bags of balloons for a party. Each bag contained 70 balloons. Andy said Mrs. Ruiz bought a total of 75 balloons. Andy is incorrect. What error did Andy make when calculating the total number of balloons? And What is the total number of balloons Mrs. Ruiz bought?
Answer:
Andy made the error of adding the values of the bags and the ballons, when instead they should be multiplied. The total number of baloons Mrs. Ruiz bought is 350 because 70*5 is 350. You multiple because there are five bags and in each of the five bags, there are 70 balloons.
What is the slope of the line passing through the points (0, 4) and (6, 13)
Answer:
The slope is [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Hi there!
We are given the points (0, 4) and (6, 13)
We want to find the slope of the line containing these two points
Slope (m) is the steepness of the line. When calculating from two points, you use the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
Although we have what we need to find the slope, let's label the values of the points to avoid confusion and mistakes.
[tex]x_1=0\\y_1=4\\x_2=6\\y_2=13[/tex]
Substitute these values into the equation
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{13-4}{6-0}[/tex]
Subtract
m=[tex]\frac{9}{6}[/tex]
Simplify
m=[tex]\frac{3}{2}[/tex]
The slope of the line is 3/2
Hope this helps!

A weight attached to a spring is at its lowest point, 9 inches below equilibrium, at time t = 0 seconds. when the weight it released, it oscillates and returns to its original position at t = 3 seconds. which of the following equations models the distance, d, of the weight from its equilibrium after t seconds? d = negative 9 cosine (startfraction pi over 3 endfraction t) d = negative 9 cosine (startfraction 2 pi over 3 endfraction t) d = negative 3 cosine (startfraction pi over 9 endfraction t) d = negative 3 cosine (startfraction 2 pi over 9 endfraction t)
The equation which models the distance (d) of the weight from its equilibrium after time (t) is equal to d = -9cos(2π/3)t.
What is the period of a cosine function?The period of a cosine function simply means the total length (distance) of the interval of values on the x-axis over which a graph lies and it's repeated.
Since the weight attached is at its lowest point at time (t = 0), therefore, the amplitude of equation will be negative nine (-9)
For the angular velocity at time period (t = 3s), we have:
ω = 2π/T
ω = 2π/3
Mathematically, the standard equation of a cosine function is given by:
y = Acos(ω)t
Substituting the given parameters into the formula, we have;

The probability of picking two baseballs is 3/20.
The probability of picking a baseball then a football is 1/12.
The probability of picking two footballs is 1/30
What is the probability?Probability is used to calculate the likelihood of an event happening. The odds the event occurs is 1 and the probability that the event does not occur is 0.
The probability of picking a golfball then a basketball = 7/25 x 3/24 = 7/200
The probability of picking two baseballs = 10/25 x 9/24 =18/120 = 3/20
The probability of picking a baseball then a football = 10/25 x 5/24 = 1/12

Quadratic functions g (x) and h (2) are graphed on the same coordinate gri
The vertex of the graph of h (2) is 12 units above the vertex of the graph
of g (2).
Which pair of functions could have been used to create the graphs
The derivative of h(x) in A is 2x+24
h'(x)=0 g'(x)=0
2x+24=0 2x=0
x=-12 x=0
Similarly the derivative of h(x) in D is 2x-24
h'(x)=0 g'(x)=0
x=12 x=0
Knowing that B & C give the same x-value when solving for the derivative=0We know that the only difference comes down to the y-value when substituting x=0 in h(x).
The y-value of the vertex of h(x) must be +12 the y-value of the vertex of g(x).
We have to add 12 to get to the x-value, which means that the third option or C is your answer.
Prove or disprove that the point (√5, 12) is on the circle centered at the origin and containing the point (-13, 0). Show your work.
Using the equation of the circle, it is found that since it reaches an identity, the point (√5, 12) is on the circle.
What is the equation of a circle?
The equation of a circle of center [tex](x_0, y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
In this problem, the circle is centered at the origin, hence [tex](x_0, y_0) = (0,0)[/tex].
The circle contains the point (-13,0), hence the radius is found as follows:
[tex]x^2 + y^2 = r^2[/tex]
[tex](-13)^2 + 0^2 = t^2[/tex]
[tex]r^2 = 169[/tex]
Hence the equation is:
[tex]x^2 + y^2 = 169[/tex]
Then, we test if point (√5, 12) is on the circle:
[tex]x^2 + y^2 = 169[/tex]
[tex](\sqrt{5})^2 + 12^2 = 169[/tex]
25 + 144 = 169
Which is an identity, hence point (√5, 12) is on the circle.

What is equation?A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical. For examples, in the equation 3x + 5 = 14, because equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another. The emblem and the particular piece of software are usually identical. like, for instance, 2x - 4 = 2.
The two lines' equations are y = 1/4 (x - 4) and y = 1/4 (x - 1)
By equating them, we obtain: 1/4(x - 4) = 1/4x - 1.
To get rid of the fractions, multiply both sides by 4 as follows: x - 4 = x - 4
This equation may be written as 0 = 0, which is a constant.
The two lines coincide and have an endless number of solutions as a result.

The period of the cosine function is The equation of the midline of the cosine function is y = 20 The amplitude of the cosine function is
Answer:
The period is the change in x required for the function to return to the same value, changing in the same direction. The first two table entries are v(x) = 41.7 and 35.7. The next time that sequence appears is when x=44, so the period is ...
period = 44 -4 = 40 . . . seconds
__
The minimum table value is 20; the maximum is 44, so the midline of the function is their average:
midline = (20 +44)/2 = 32
__
The amplitude is the maximum deviation from the midline, so is ...
amplitude = 44 -32 = 12
