On the first two pairs you need to write 3 and 4, and 6 and 2.
On the second page we have:
1) 4
2) 2 and 7
3) 1
4) 1 and 3
5) 3.
What numbers go in the squares?
a) Here we just need to use scientific notation.
For the first case, the numbers that go in the exponent boxes are the same ones that go in the example, which are 4 in the first one and 2 on the second one.
Then, if we want the difference to be 29,400, then we can use 3 on the first box and 6 on the second. OR, because this is an absolute value, we can just invert those.
This is:
6 and 2 on the first two squares, and 3 and 4 on the second two squares.
b) Here we want to make perfect squares.
For example, on the first case we have:
x*2*2
We need to find the value of x such that this is a perfect square. Notice that we can rewrite this as:
x*2*2 = x*4
Then it only is a perfect square if x = 4.
For the second case:
14*x*y
This is only a perfect square if x*y = 14
Then we can use x = 2 and y = 7.
With similar reasoning, on the next box we have:
2*8*x
2*8 = 16, is already a perfect square, so x = 1.
The next one is:
x*3*y
Here we can define x = 3 and y = 1, so we get a perfect square.
Finally:
3*x
Here the only possible value of x is 3.

Answers
Answer:
$15
Step-by-step explanation:
Range is the difference of the highest and lowest data.
Based on the given $20 is the highest and $5 is the lowest.
$20 - $5 = $15
Answer:
15
Step-by-step explanation:
you can think of this table as a data set--and you could even write it out
5, 5, 5, 10, ......... 20, 20 {I did not write it out in full of course}
so, when thinking about the range, we can think of it as a range of our data set.
We find the range of a data set by finding the difference between the highest and lowest values
So, we know that our highest data value (amount) is 20, and the lowest is 5:
20 - 5 = 15
meaning that there is a range of $15 in this data set of allowance amounts

Answer:

Step-by-step explanation:
When it says "rate of change", it's really just asking for the slope. If you don't know what the slope is, essentially how much the y-value increases by whenever x increases by 1. This can be formally defined using the equation: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] which is essentially [tex]\frac{rise}{run}[/tex]. The subtraction is finding the difference between the two numbers to see how much it's changed by. Btw the order doesn't matter, I could plug in (-3, -2) as (x2, y2) or I could plug it in as (x1, y1) as long as I make sure to input it in correctly. In this example I'll just say (-3, -2) = (x1, y1) and (2, 4) = (x2, y2). Plugging these values into the equation gives you: [tex]\frac{4- (-2)}{2- (-3)} = \frac{6}{5}[/tex] that's the rate of change

We can find the graph by finding the roots of the equation.
Since the equation is already in factored form, we can use the Zero Product Property to find the roots. The roots of an equation are the value(s) of x when y is 0 (x-axis).
Find the Rootsy = (x - 2)(x - 3)0 = (x - 2)(x - 3)0 = (x - 2)x = 20 = (x - 3)
x = 3
The roots of the equation are 2 and 3. That means the graph intersects the x-axis at points 2 and 3. Looking at the graphs shown, the answer is Option A.

Line segment pq is a directed line segment beginning at p(6,-5) and ending at q(-2,4). find point r on the line segment pr that partitions it into the segments pr and pq in the ratio 3:2.
Answers
Using proportions, the coordinates of point R are given as follows: R(1.2, 0.4).
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Segments pr and pq are partitioned in the ratio 3:2, hence:
[tex]PR = \frac{3}{5}PQ[/tex]
[tex]R - P = \frac{3}{5}(Q - P)[/tex]
The points are:
R(x,y).P(6,-5).Q(-2,4).For the x-coordinate, we have that:
[tex]R - P = \frac{3}{5}(Q - P)[/tex]
[tex]x - 6 = \frac{3}{5}(-2 - 6)[/tex]
x - 6 = -4.8
x = 1.2.
For the y-coordinate, we have that:
[tex]R - P = \frac{3}{5}(Q - P)[/tex]
[tex]y + 5 = \frac{3}{5}(4 + 5)[/tex]
y + 5 = 5.4.
y = 0.4.
The coordinates are: R(1.2, 0.4).

the ratio of girl to boys is 6 2, there were 14 boys how many total members were there in the club
Answers
Answer:
The club has 56 members
Step-by-step explanation:
We can set up a ratio problem to find the total number of kids in the club. There are two ways to do this, and I will show you both. The first way is to immediately set up a ratio between the number of boys and the number of total members in the club. Since the ratio of girls to boys is 6:2, the ratio of boys to members is 2:8 (add the number of girls and boys in the ratio to get the total number of people). Now, we can set up an equation, letting x equal the number of members total, and solve using cross multiplication:
[tex]\frac{2}{8}=\frac{14}{x}\\\\ 112=2x\\\\ x=56[/tex]
The other way to solve this problem would be to figure out the number of girls in the club if there are 14 boys and then add the two quantities together. If we let y be the number of girls in the club, we get the following solution:
[tex]\frac{6}{2}=\frac{y}{14}\\\\ 2y=84\\\\ y=42\\\\x+y=56[/tex]
Either way, we get that the total number of members is 56

Answers
The experimental probability is 5/14.
What is Experimental Probability?The term "probability" refers to an event's likelihood of happening. A probability has a value between 0 and 1, therefore if an occurrence is impossible, it has a probability of 0, and if it is certain, it has a probability of 1. Experimental probability is the probability that is established based on the outcomes of an experiment. The term "empirical probability" also applies to this. A probability that has been established by a series of tests is called an experimental probability. To ascertain their possibility, a random experiment is conducted and iterated over a number of times; each iteration is referred to as a trial. The goal of the experiment is to determine the likelihood that an event will occur or not.Since, 4 appeared five times over the total, The experimental probability is 5/14.

The quadratic equation is y = 1/2x^2 - 3x + 4
How to determine the equation?A quadratic equation is represented as:
y = ax^2 +bx + c
Using the values on the table, we have:
a(0)^2 + b(0) + c = 4 ---- when x = 0
a(2)^2 + b(2) + c = 0 ---- when x = 2
a(4)^2 + b(4) + c = 0 ---- when x = 4
Evaluate these equations
c = 4
4a + 2b + c = 0
16a + 4b + c = 0
Substitute c = 4
4a + 2b + 4 = 0
16a + 4b + 4 = 0
Divide through by 2 and 4
2a + b + 2 = 0
4a + b + 1 = 0
Subtract both equations
2a -1 = 0
Solve for a
a= 1/2
Substitute a= 1/2 in 4a + b + 1 = 0
4 * 1/2 + b + 1 = 0
Evaluate
2 + b + 1 = 0
Solve for b
b = -3
So, we have:
y = ax^2 +bx + c
This gives
y = 1/2x^2 - 3x + 4
Hence, the quadratic equation is y = 1/2x^2 - 3x + 4

What is the smallest possible length of the hypotenuse for a non-degenerate
right triangle with integer side lengths given that it has at least 1 leg of length
84.
Answers
The smallest possible length of the hypotenuse is 118
How to determine the hypotenuse?The given parameters are:
Triangle type: non-degenerate right triangleLegs: Length = 84 (at least 1)The non-degenerate implies that the right triangle has a positive area.
Since at least one length is 84, then both lengths can also be 84.
The hypotenuse is then calculated using the following Pythagoras theorem.
h^2 = 84^2 + 84^2
Evaluate the sum
h^2 = 14112
Take the square root of both sides
h = 118.8
Round down
h = 118

b. The tens digit of a number is b and the units digit is twice as big. What is the value of the number in terms of b if the digits are reversed?
I hope you can help me with these questions!!
Answers
For the given sentences, the algebraic expressions are:
a) N = 110*c - 300
b) N = 12*b
How to get the algebraic expressions?
For the first statement:
A 3-digit number, where the tens digit is c, can be written as:
N = 100*a + 10*c + b
Then the hundreds digit is a, and here we know that is 3 less than the tens digit, then:
a = c - 3
The ones digit is b, here we know that it is 0, then b = 0.
Replacing that in our number we get:
N = 100*(c - 3) + 10*c = 110*c - 300
N = 110*c - 300
That is the algebraic expression.
b) A two-digit number can be written as:
N = b*10 + a
Where b is the tens digit and a is the ones digit.
Here we know that the units digit is twice as bit as the tens digit, then:
a = 2b
Replacing that we get:
N = b*10 + a = b*10 + 2b = 12*b
N = 12*b
That is the algebraic expression.
