Answer:
2[(1 + 5x) (1 - 5x)]
Step-by-step explanation:
Given:
Expression
2 - 50x²
Find:
Factorization of the given expression
Computation:
2 - 50x²
By taking 2 as common
⇒ 2[1 - 25x²]
⇒ 2[(1)² - (5x)²]
We know that;
⇒ a² - b² = (a + b)(a - b)
In given expression;
⇒ a = 1
⇒ b = 5x
⇒ 2[(1)² - (5x)²]
2[(1 + 5x) (1 - 5x)]
Factorization of the given expression
2[(1 + 5x) (1 - 5x)]

Answer:
x = 36 degrees
Step-by-step explanation:
Every Triangle adds up to 180 degrees so in order to solve this we must add together the two angle we know which is
97 + 47 = 144
Then we take this number and we subtract is from 180 to find the third angle
180 - 144 = 36
Darla needs to be at her babysitting job at 6:00 pm. It takes her 15 minutes to ride her bike to the job, 25 minutes to eat dinner, and 40 minutes to do her homework. Use the number line to find the time Darla needs to start her homework.
Answer:
Assuming she has to do all of that before she leaves she needs to start at 4:40pm
Step-by-step explanation:
All of the things needed to do before she leaves equals 80 min and that is 1 hour and 20 min. Subtract that from 6:00pm and you get 4:40pm.

You are road tripping down the California coast and you notice you need to fill up your gas tank. In CA, sales tax is 2.25%. You spend $56.00 to fill up your tank. How much are you paying in sales tax?
Answer:
$1.26
Step-by-step explanation:
So you just have to find 2.25% of 56.
To find a certain percentage of something, you multiply it. Let's write out a sentence explaining what you need to do. You have to find:
2.25% of 56
Whenever you've got a sentence like this, all you've got to do is change the word "of" to a multiplication symbol. And now you've got an expression:
2.25% × 56
Let's convert the percentage to a decimal. To do this, you simply remove the percent symbol, then move the decimal point 2 places to the left.
2.25% = 0.0225
And now you have:
0.0225 × 56
Then you just do the math! I am assuming you already know how to do decimal multiplication so I'm not going to explain the process here.
But once you multiply 0.0225 × 56, you get an answer: 1.26

Roll the number cube to find the observed frequency. Which statements are true? Check all that apply
Answer:
(a) and (c)
Step-by-step explanation:
Given
See attachment for complete question
Required
Select all true statements
First, calculate the total observed frequency;
[tex]Total = 11 + 16 + 14 + 20 + 12 + 17[/tex]
[tex]Total = 90[/tex]
(a): Relative frequency of 4 is 2/9
Relative frequency is calculated by:
[tex]RF= \frac{Observed\ Frequency}{Total}[/tex]
For roll 4
[tex]Observed\ frequency = 20[/tex]
So, the relative frequency is:
[tex]RF = \frac{20}{90}[/tex]
Simplify
[tex]RF = \frac{2}{9}[/tex]
(a) is true
(b): Experimental probability of 3 greater than its theoretical probability
The experimental probability is its relative frequency;
For roll 3
[tex]Observed\ frequency = 14[/tex]
The experimental probability is:
[tex]Pr = \frac{14}{90}[/tex]
Simplify
[tex]Pr = \frac{7}{45} = 0.156[/tex]
To calculate the theoretical probability, w have:
[tex]S = \{1,2,3,4,5,6\}[/tex] ---- sample space
[tex]n(S)= 6[/tex]
[tex]n(3) = 1[/tex] --- number of times 3 occur
The theoretical probability is:
[tex]Pr = \frac{1}{6} = 0.167[/tex]
The theoretical probability is [tex]greater\ than\ the[/tex] experimental probability.
(b) is false
(c): Experimental probability of 2 greater than its theoretical probability
Using the explanations in (b), we have:
For roll 2
[tex]Observed\ frequency = 16[/tex]
The experimental probability is:
[tex]Pr = \frac{16}{90}[/tex]
Simplify
[tex]Pr = \frac{8}{45} = 0.178[/tex]
To calculate the theoretical probability, we have:
[tex]n(S)= 6[/tex]
[tex]n(2) = 1[/tex]
The theoretical probability is:
[tex]Pr = \frac{1}{6} = 0.167[/tex]
The experimental probability is [tex]greater\ than\ the[/tex] theoretical probability.
(c) is true
(d): Relative frequency of 5 is 2/13
For roll 5
[tex]Observed\ frequency = 12[/tex]
The relative frequency is:
[tex]RF = \frac{12}{90}[/tex]
Simplify
[tex]RF = \frac{2}{15}[/tex]
(d) is true

The equation of the red graph is,
⇒ y = x² + 4
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The equation of blue graph is,
⇒ y = x²
Since, We have;
The red graph is 4 unit up from the blue graph.
Hence, The equation of the red graph is,
⇒ y - 4 = x²
⇒ y = x² + 4
Therefore, The equation of the red graph is,
⇒ y = x² + 4

Part B If the percentages are the same throughout the grade, how many girls are in the whole seventh grade if there are 150 seventh graders? Please help me answer ;)
Part B: 65
Step-by-step explanation:Part A: Since there are 30 students of the class and 17 are boys, there are 13 girls. 13/30 = 43.33 = 43%.
Part B: Since 43% of the class are girls, we do 150*0.43 for the whole 7th grade which is 64.5 which I rounded to 65.

The probability of the complement of event A P(Ac), which is the event of a place to not be a city, is 4/7. Option C is correct.
How to find the probability of an event?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
A place from this table is chosen at random. Let event A= the place is a city.
The total number of places are 7 given in the table.There are total three places which are city. Thus, the probability of a country to be a city is,
[tex]P(A)=\dfrac{3}{7}[/tex]
Now, for its complement, the probability of a place not be a city is,
[tex]P(A^c)=1-\dfrac{3}{7}\\P(A^c)=\dfrac{7-3}{7}\\P(A^c)=\dfrac{4}{7}[/tex]
Thus, the probability of the complement of event A P(Ac), which is the event of a place to not be a city, is 4/7. Option C is correct.

Tony has 75 dollars to spend on a game controller that costs $35 and used video games
costing 8 dollars each. How many video games can he buy?
Answer:5 I think
Step-by-step explanation:
75-35=40 40 divided by 8 is 5
Answer:
The answer is 5=x (he is able to buy 5 videogames)
Step-by-step explanation:
First, you need to put this into an equation format with a variable (x) for the videogames. Here is what the equation should look like: 75 = 35 + 8x
75 being the total amount of money he has to spend, 35 being what he had to spend or knows he will spend on the controller, and the 8 is for each videogame. We put an 'x' behind the 8 to signal that we don't know how many games he can buy. So, then we need to solve the equation.
75=35+8x
-35 on both sides
So, 40=8x, then you divide by 8 to get x by itself
5=x
The 'x' in this equation is how many videogames he is able to buy. The way you could check your work is if you plugged 5 back into x. What I mean is this: 35+8(5) needs to equal 75, and it does, so you're good!
