How to find the fraction of the bouncing ballGiven data
A ball is dropped from a height of 180 inches
After the second bounce it is still 5 inches
the height the ball bounces is always the same fraction of the height reached on the previous bounce
Let the first height be x, this the initial drop height = 180
Let the second height be, the first bounce y
Let the third height be w, the second bounce = 5
the fraction is said to be:
height of y / height of x = height of w / height of y
y / x = w / y
y / 180 = 5 / y
y^2 = 180 * 5
y^2 = 900
y = √900
y = 30
the fraction is then 30 / 180 = 1 / 6

What is the ratio of blue paint to total paint in the mixture?
The ratio of blue paint to the total paint in the mixture is 5:8.
How is a ratio calculated?Ratios contrast two figures by ordinarily dividing them. The term "antecedent" refers to the dividend and "consequent" to the divisor. A ratio in mathematics demonstrates how many times one number is present in another.It is a comparison or relationship between two amounts of the same quantity to determine how much larger one number is than the other. Where b is not equal to zero, it is expressed as a/b or a: b.Given:
In the figure, there are 10 blocks of blue paint and 6 blocks of red paint.
Total paint in the mixture = 10+6 = 16
Ratio of blue paint to total paint = 10/16 = 5/8

Group of answer choices
1/2 cup of broccoli per beef
1 and ½ cup of broccoli per beef
2/3 pound of broccoli per beef
5/4 cup of broccoli per beef
Proportionately, the number of cups of broccoli needed for a pound of beef is B. 1 and ½ cups of broccoli per beef.
What is proportion?Proportion refers to the numerical quantity or relationship of one variable to another, which are set equal to each other.
Proportions, like ratios, use fractional values because they show the quantity of one variable in another.
We state proportions in fractions, decimals, or percentages.
The proportion of 3/4 pound of beef to broccoli = 9/8 cups of broccoli
3/4 pound = 0.75 pound
9/8 cups = 1.125 cups
The number of cups of broccoli for a pound of beef = 1.5 cups (1.125/0.75)
1.5 cups = 1½ cups
Thus, given the proportional relationship presented, for a pound of beef, Tyler would need 1½ cups of broccoli.

In the diagram below ∠1≅∠2 and m∠CFB=124°. Find each of the following.m∠1=___m∠2=___ m∠3=___m∠4=___m∠CFB= 124°
Angles and lines
We are given the following information
Angle 1 is congruent with angle 2. They have equal measures
Angle CFB measures 124°
Note that angles 4 and F are linear because they are formed by the intersection of two lines.
Linear angles add up to 180°
This means that the measure of angle 4 is:
m angle 4 = 180° - m CFB
m angle 4 = 180° - 124°
m angle 4 = 56°
now note angle 4, 1, and 2 form a straight angle of 180°. This means that
m angle 4 + m angle 1 + m angle 2 = 180°
Since angles 1 and 2 are congruent:
m angle 4 + 2* m angle 1 = 180°
Knowing that m angle 4 = 56°:
56° + 2* m angle 1 = 180°
Subtracting 56°:
2* m angle 1 = 124°
Solving:
m angle 1 = 124° / 2 = 62°
Thus, both angles 1 and 2 measure 62°
Finally, being angles 3 and 4 vertical angles (opposed by a vertex), they are congruent, thus
m angle 3 = m angle 4 = 56°

The line y=kx+4 goes through the point (2,-2)
K=-3
Sketch the graph of the line (need ASAP!!)
We can see that the value of k is -3, then the line is:
y = -3*x + 4
By finding two points of the line, we can graph the line like in the image you can see below.
How to sketch a graph of the line?
Here we have the following linear equation:
y = k*x + 4
We know that this line goes through the point (2, -2), then we can replace these values in the above equation so we get the value of k.
-2 = k*2 + 4
Solving this, we can find the value of k.
-2 - 4 = k*2
-6 = k*2
-6/2 = k = -3
So the value of k, the slope of the line, is k = -3.
Then the line is:
y = -3*x + 4
If we evaluate in x = 1, we get:
y = -3*1 + 4 = 1
So, at this point we know that the line passes through points (1, 1) and (2, -2).
Now we can draw these two points on a coordinate axis, and then connect them with a line. That will be the graph of the linear equation.

Find the coefficient of the x^2 term in the expansion of (5x-2)^6 //Series and sequences precalculus
We need to expand the term:
[tex](5x-2)^6[/tex]This seems like a colossal task, we would need to multiply (5x-2) 6 times. However, we can use a useful tool that is called the 'Pascal's triangle'
I'll paste an image of it above
We will use it in this way:
Each one of the rows, represent the n in the term:
[tex](x+y)^n[/tex]So, if we have the expression (x+y) we will pay attention to the upper row, if we have (x+y)^2 we will need the second row, and so on.
In our case, we need the 6th row.
Now, usually a term of the form
[tex](x+y)^6=ax^6+bx^5y+cx^4y^2+dx^3y^3+ex^2y^4+fxy^5+gy^6[/tex]As we say, look at the 6th row of the triangle, the numbers a, b, c,..., and g are given there!
[tex]\begin{gathered} a=1 \\ b=5 \\ c=10 \\ d=10 \\ e=5 \\ f=1 \end{gathered}[/tex]And we need the term that corresponds to x^2, we need the number e=5!

You want a system of inequalities that will define the area within the triangle with vertices (-2, 1), (1, 7), and (4, -2), including only the left side.
Linear equationsAn equation through points (x1, y1) and (x2, y2) can be written as ...
(y2 -y1)x -(x2 -x1)y = x1·y2 -x2·y1
Removing any common factor from the coefficients, and making sure the leading coefficient is positive will put this in standard form.
For points (-2, 1) and (1, 7), the equation of the line can be ...
(7 -1)x -(1 -(-2))y = (-2)(7) -(1)(1)
6x -3y = -15 . . . simplify
2x -y = -5 . . . . . divide by 3 (shading is right of the solid line)
For points (1, 7) and (4, -2), the equation of the line can be ...
(-2 -7)x -(4 -1)y = (1)(-2) -(7)(4)
-9x -3y = -30 . . . simplify
3x +y = 10 . . . . . . divide by -3 (shading is left of the dashed line)
For points (4, -2) and (-2, 1), the equation of the line can be ...
(1 -(-2))x -(-2 -4)y = (4)(1) -(-2)(-2)
3x +6y = 0 . . . simplify
x +2y = 0 . . . . divide by 3 (shading is right of the dashed line)
InequalitiesIn each of the above equations, the x-coefficient is positive. This means the equal sign can be replaced with > when shading is right of the line, and with < when shading is left of the line.
There will be an "or equal to" symbol when the line is solid.
This means our inequalities are ...

The area of triangle ABC is 17.5 or 35/2
To solve this, we need to know the base and height of the triangle.
In this case, the base is the side AB, and the height is the side BC

AB is 7 units long
BC is 5 units long.
Now we can use the formula for the area of a triangle:
[tex]A=\frac{bh}{2}[/tex]Where A is the area, b is the base and h is the height.
Putting the values of b and h:

he writes down his mileage before and after he has made his journey. this journey takes 2h and 45minutes.
how much does he charge to deliver these goods?
Answer:

Step-by-step explanation:
Time charge = 2.75 hr * £7.00/hr = £ 1`9.25
Mileage charge = ( 25423 - 25263) mi * 40p / mile = 6400 p

what we were not told is, if he charges a full hour for a fraction of an hour, or only a corresponding fraction of his hourly rate.
I assume the first : charging a full hour for any fraction of an hour spent.
it took him 2h and 45 minutes, so that is 3 hours charged.
and he was driving

For the linear function y = 2/3x + 1 given in this problem, we have that:
a) The slope is of 2/3 and the intercept is of 1.
b) The y-intercept is marked at y = 1 on the y-axis.
c) Using the slope and the intercept, point (3,3) is the second point used to graph the function.
d) The graph of the linear function y = 2/3x + 1 is given at the end of the answer.
How to we graph the linear function?In slope-intercept format, a linear function is defined as follows:
y = mx + b.
For this problem, the function is:
y = 2/3x + b.
Hence:
The slope is of m = 2/3, meaning that when the input x increases by 3, the output y increases by 2.The intercept is of b = 1, meaning that the graph of the function crosses the y-axis(vertical axis), at y = 1.From the intercept, we know that point (0,1), which has x = 0 and y = 1, is part of the graph of the function.
Considering the concept of the slope, of change in y divided by change in x, we have that:
y + 2 = 1 + 2 = 3.x + 3 = 0 + 3 = 3.Hence point (3,3) also belongs to the graph of the given function. Given two points, we can graph a line passing through them, hence the graph is given at the end of the answer, and represents the function y = 2/3x + 1.

The Royal Fruit Company produces two types of fruit drinks. The first type is 65% pure fruit juice, and the second type is 90% pure fruit juice. The company is attempting to produce a fruit drink that contains 70% pure fruit juice. How many pints of each of the two existing types of drink must be used to make 30 pints of a mixture that is 70% pure fruit juice?
20 of the 65 percent pure fruit juice, 10 of the 90 percent pure fruit juice.
What is percentage ?A fraction that is parts out of 100 is referred to as a percentage.100% is the totality. The percentages that make up a whole add up to 100%.When representing a percentage as a number, the % symbol is used. A decimal, fraction, mixed number, integer, or other type of number can be used.In a grid of 100 squares, shading can be used to represent a percentage.
First, we define our variables: let x be the number of pints of the first fruit drink (65% pure fruit juice), and y be the number of pints of the second fruit drink (90%pure fruit juice).
We know that there are 30 total pints of the mixture. Thus:
x+y=30
We also know that 90%of those 30 pints will be pure fruit juice, and all of the pure fruit juice will come from xor y.
For x pints of the first juice, there is .65x pure fruit juice. Similarly, for ypints of the first juice, there is .90y pure fruit juice. Thus, we get:
.65x+.90y=30 ×0.7
Now we solve. First I'll get rid of the decimals in the second equation by multiplying by 100:
65x+90y=2100
Multiply the first equation by 65 on both sides to be able to cancel out one of the terms:
65x+65y=1950
Subtract the second equation from the first equation:
25y=250
y=10
Thus, we need 10 pints of the second fruit juice (90%pure fruit juice). This means that we need 30−10=20 pints of the first fruit juice (65% pure fruit juice).
