All Vocabulary words learned in 2020
A base is the number being used as a factor in an exponential expression.
An exponent is the number that shows how many times a base is used as a factor.
An equation is a statement that tells you two expressions are equivalent.
A cube root is any number that is multiplied together three times to get the original number.
A perfect cube is the product of an integer multiplied together three times.
A repeating decimal is a decimal that never ends but instead repeats the same digit or group of digits over and over.
A terminating decimal is a decimal that ends, or terminates.
An irrational number is a number that cannot be expressed as the quotient of two integers. The decimal never terminates or repeats.
A rational number is a number that can be expressed as the quotient of two integers.
A power of ten is a number that can be written as a product of tens.
Scientific Notation is a way to express a number as the product of a number greater than or equal to 1 but less than 10 and a power of ten.

The slope is negative and the line intersects the y-intercept at positive 2.
Solve for X showing every step
Answer:
x = 1
Step-by-step explanation:
3(x + 6) -5 = 16
You want to first add the 5 (*flipping the sign) over to the 16
making your equation ...
3(x +6) = 21
Then you want to distribute the 3 to x and 6
making you equation
3x + 18 = 21
Then you want to subtract the 18 (*flipping the sign) to the right side
making the equation....
3x = 3
Lastly, divide the 3 on the left to the 3 on the right making the answer 1
x = 1

Answer:
1/6
Step-by-step explanation:
Add all the toys together: 6 + 5 + 4 + 3 = 11 + 7 = 18
There's 18 toys in total, 3 out of 18 of the toys are teddy bears so it's 3/18 but u have to check if u can simplify it, which u can. 3/18 simplified is 1/6, we can't simplified it anymore so 1/6 is ur answer
Answer: Probability of teddy = 1/6
Step-by-step explanation:
6 + 5+ 4 + 3 = 18

Slope formula: y2-y1/x2-x1
Step-by-step explanation:
8-6/9-6= 2/0
Answer:
Step-by-step explanation:
Alright we need to prove that both the triangles are similar so lets get started
The slope formula is:
Slope = Change in y / Change in x
m = Δy / Δx
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\[/tex]
Where, m is the slope and [tex](x_1,y_1) , (x_2,y_2)\\[/tex] are any points on the line
In this graph we are given three points which are
(0 , 2) , ( 6 , 6) and (9 , 8)
So for our first triangle we use the 2 points (0 , 2) and (6 ,6) and calculate the slope,
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{6-2}{6-0}\\\\m=4/6\\\\m=2/3\\[/tex]
So the slope turns out to be 2/3 , Now for our second triangle use the 2 points (6 , 6) and (9 , 8)
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{8-6}{9-6}\\\\m=2/3\\[/tex]
So we can see the the slope's are equal that's the answer to your first part.
Second part
Yes they are similar due to the property of corresponding angles where angle x of the first triangle equals angle x for the second triangle and angle y for the first triangle equals angle y for the second triangle and both the triangles have 90° se they are similar because all three angles are similar. (AAA = angle angle angle property) I have attached a to make you understand it better.
Which number is equal to the expression 7 x 104 + 3 x 103 + 0 x 102 + 8 x 101 + 5 ?
Answer:
1
Step-by-step explanation:
Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work?
We can think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term).
Here are some examples of scientific notation

A saleswoman is paid $80 a day plus $6 for each sale she makes. She wants to earn more than $150 today. Write an inequality that represents the number of sales, x, the saleswoman must make today to earn more than $150. What is the least number of sales she must make to reach her sales goal
Answer:
12
Step-by-step explanation:
Given that:
Daily wages paid to a saleswoman = $80
Wages paid for each sale made by her = $6
Target of today's earnings = more than $150
To find:
Least number of sales to be made so that the total earnings today is more than $150.
Solution:
Number of sales for today = [tex]x[/tex]
Wages for one sale = $6
Wages for [tex]x[/tex] number of sales = $6[tex]x[/tex]
Total earnings = Per day sales + Wages for [tex]x[/tex] number of sales > $150
[tex]80 + 6x > 150[/tex]
we need to solve for above inequality to find the least number of sales to be made to meet the goal.
Subtracting 80 from both sides:
[tex]\Rightarrow 6x>70\\[/tex]
Dividing both sides by 6:
[tex]\Rightarrow x > 11[/tex]
Therefore, at least 12 sales must be made.
Convert 34,121 to Scientific Notation
Answer:
3.4121 * 10 ^4
Step-by-step explanation:
34,121 is same as
3.4121 * 10 ^4
because the first number has to be between 0 and 10 and if you move the decimal 4 places to the right you got the initial number
Sean is getting balloons for his grandfather's birthday party. He wants each balloon string to be 9 feet long. At the party store, string is sold by the yard. If Sean wants to get 66 balloons, how many yards of string will he need?
Answer:
198 yards
Step-by-step explanation:
Sean wants the sting of each balloon to be 9 feet, and he wants to get a total of 66 balloons.
The total length of stings required for 66 balloons would be;
total length of balloon strings = 66 x 9 feet
= 594 feet
But the string is sold by the yard at the store.
So that,
1 yard = 36 inches = 3 feet
x yard = 594 feet
Thus,
x = [tex]\frac{594}{3}[/tex]
= 198 yards
x = 198 yards
Therefore, the total length of string that Sean would need is 198 yards.

A line is perpendicular to the line given by the equation - 8 = 2y + 3x. What is the slope of the perpendicular line? 3
Answer:
2/3 is the slope of the perpendicular line
Step-by-step explanation:
1) put into slope-intercept form (y=mx+b)
-8=2y+3x
-2y=3x+8
y=-3/2x-4
2) the line is perpendicular so the slope will be opposite and the reciprical of the original slope.
so, because the original was -3/2, the new one is 2/3
