replace x in each problem with 5 since x equals 5.
5<2 ,, false
5>9 ,, false
5<18,, true
5>42,, false
Answer:
C
Step-by-step explanation:
A isn’t correct because it says 5<2, 5 is less then 2, which isn’t correct. B isn’t correct because it says 5>9, 5 is greater then 9, which isn’t correct. C is correct because it says 5<18, 5 is less then 18, which is correct. D isn’t correct because it says 5>42, 5 is greater then 42, which isn’t correct.

Answer:
x > 10.5
Step-by-step explanation:
The point is on 10.5
The point is open which means that 10.5 is not included in the solution and we will be using < or >
The line is pointing towards numbers that are greater than 10.5 Which means that x is greater than 10.5
Hence, the answer is x > 10.5

Solve the x
3(1.5x + 9)= -9
Answer:
x = -8
Step-by-step explanation:
3(1.5x + 9) = -9
Divide both sides by 3
1.5x + 9 = -3
Subtract 9 from both sides
1.5x = -12
Divide both sides by 1.5
x = -8
Answer:
x = -8Step-by-step explanation:
3(1.5x + 9)= -9
=> 4.5x + 27 = -9
=> 4.5x = -9-27
=> 4.5x = -36
[tex] = > \frac{45x}{10} = - 36[/tex]
[tex] = > x = - 36 \times \frac{10}{45} [/tex]
[tex] = > x = - 4 \times \frac{10}{5} [/tex]
=> x = -4 × 2
=> x = -8 (Ans)
Can someone give me a small lesson on nets and surface areas??
Thank you if you can. I really don’t understand.
Hi!
Here is the definition of a net from www.icoachmath.com:
“Net is a two-dimensional pattern of a three-dimensional figure that can be folded to form the figure. In other words, net is a flattened three-dimensional figure which can be turned into the solid by folding it.”
In the photo is an example of a net of a rectangular prism.
Surface area is the measure of the total area of the surface of a 3D object. For example, if I have a cube, the surface area would be the area of the outside of the cube.
Hope this helped,

chef johnson used 4 1/2 cups of flour to make 4 fruitcake. how many cups of flour are needed for 1 fruitcake
Answer:
1 1/8 Cups of flour are needed for 1 fruitcake.

Your teacher decides to determine groups in your class by pulling names out of a hat and not replacing them. What type of even is this?
Answer:
Social Loafing
Step-by-step explanation:
In social psychology, social loafing is the phenomenon of a person exerting less effort to achieve a goal when they work in a group than when working alone. It is seen as one of the main reasons groups are sometimes less productive than the combined performance of their members working as individuals.
The event is an example of a combination.
What is a combination?It is an arrangement of a set of numbers from a total set where the order of the set is not relevant.
We have,
This event is an example of a non-replacement or non-independent event.
In probability theory, an event is said to be non-replacement or non-independent if the outcome of a previous event affects the outcome of the current event.
In this case,
Once a name is pulled out of the hat, it is not replaced, meaning that the probability of pulling out a certain name changes with each draw.
For example, if a name is pulled out of the hat, the probability of pulling out that same name again decreases because it is no longer in the hat.
Therefore,
This event is non-replacement or non-independent.

Answer:
[tex]\sqrt{18.04}[/tex]
Step-by-step explanation:
The wording is a bit confusing, but i beleive it basically means that we're trying to find the length on a leg of a triangle with a leg length of 3 and a hypotenuse of 5.2
if we write this out as an equation, it gives us:
[tex]5.2^{2}-3^{2}[/tex]
If we then simplify this, we get 27.04 - 9, which then simplifies to 18.04.
We then need to get the square root of this number to get the answer, thus the answer is [tex]\sqrt{18.04}[/tex]
Betsy started a business 2 years ago. She had 8 customers in the first year. She added 18 customers in the second year. Betsy's goal is that in each of the next 4 years, she will have three times ad many customers as the year before. Betsy shows her calculations in the TABLE below that if she meets this goal each year, she will have 312 customers 4 years from now. is Betsy correct? Use the drop-down menus to explain your reasoning.
Expression: (8 + 18) * 3^4
Step 1: 26 * 3^4 <<< TABLE
Step 2: 26 * 12
Answer: 312
Pick the correct answer in parentheses:
Betsy's calculations in Step 1 are ( is she Correct or Incorrect) because... ( .She added incorrectly .She has 26 customers at the end of her second year .She should have multiplied 18 * 3^4 before adding 8)
Besty's calculations in Step 2 are ( is she Correct or Incorrect) Because.... ( .She did not find the correct value of 3^4 .26 * 3^4 = 26 * 12 .She did not apply the order of operations correctly)
If Betsy reaches her goal each year, she will have.. ( .2,106 .312 .1,466) customers 4 years from now.
Answer: step one is correct and the second step is incorrect
Step-by-step explanation:
Answer:
Betsy isn't correct. Betsy's calculations are wrong as she made her calculations by multiplying the base number of customers by 3 and then summing it all up for the 4 years under review instead of a continuous multiplication by 3.
Step-by-step explanation:
26 × 3 × 4 is different from 26 × 3⁴
- If Betsy meets her target for the next 4 years, she will have 2106 customers in 4 years time.
- Betsy started her business 2 years ago.
- In the first year, Betsy has 8 customers.
- In the second year, Betsy added 18 customers,
- So, her customers are now 8+18 = 26
- Betsy's goal is that in each of the next 4 years, she will have three times as many customers as the year before.
If the base number of customers is truly 26 this year,
Next year, Betsy would have 26 × 3 = 78 customers.
In 2 years, she would have 78 × 3 = 234
Thus indicating that in t years from now, the number of her customers will be
N(t) = N₀ × 3ᵗ
where
N(t) = number of customers t time from now
N₀ = number of customers at the moment = 26
t = number of years from now.
N(t) = 26 × 3ᵗ
In 4 years from now, Betsy will have
N(t=4) = 26 × 3⁴ = 2,106
So, it is evident that Betsy's calculations are wrong as she made her calculations by multiplying the base number of customers by 3 and then summing it all up for the 4 years under review instead of a continuous multiplication by 3.
26 × 3 × 4 is different from 26 × 3⁴
- If Betsy meets her target for the next 4 years, she will have 2106 customers in 4 years time.

Ophelia keeps flour in a cylindrical canister. The capacity of the full canister is 75.36 in^3..When it is filled halfway the flour reaches a height of 3 in. What is the diameter of the canister?
Answer:
4 (rounded to the nearest whole number)
Step-by-step explanation:
total height = 3 x 2 = 6
Volume = radius^2 * pi * height
75.36= radius^2 * pi * 6
75.36/pi = radius^2 * 6
23,987833 = radius^2 * 6
23,987833/6 = radius^2
3,997972 = radius^2
radius = 1,999493
diameter = radius x 2 = 1,999493 x 2 = 3,998986

One–third of the product of −8 and 9
Half the sum of 8 and −6
Three times the sum of 12 and −6
One-fifth the product of 1 and −5
Five times the sum of −8 and 4
Answers:
-24
-20
-1
1
18
Answer:
down below.
Step-by-step explanation:
One–third of the product of −8 and 9 = -24
-8(9) = -72
-72 / 3 OR -72(1/3) = -24
Half the sum of 8 and −6 = 1
8 + (-6) =2
2 / 2 = 1
Three times the sum of 12 and −6 = 18
12 + (-6) = 6
6 * 3 = 18
One-fifth the product of 1 and −5 = -1
1(-5) = -5
-5/5 = -1
Five times the sum of −8 and 4 = -20
-8 + 4 = -4
-4 * 5 = -20

KING OF QUESTIONS!!!
Step-by-step explanation:
Each player starts out with 10 tokens ( tokens can be anything I recommend spare change or coins. ) the tokens will be used as point tallies at the end of the game. But to determine who goes first the question master asks a question from the starting deck( The easiest questions) and starting with player one the players answer and whoever answers with the correct answer will go first, the other players will form an orderly line from closest to the correct answer to farthest. ( If there are more than 1 successful answers you pull another card from the next deck. This is an increase in difficulty. And it will keep increasing until there is one person with the correct or closest answer or until they reach the end of the final deck. Remember that this event is highly unlikely) After this is done the game begins. The question master asks a question the players will answer. The players that get it correct will receive 2 token. The players that do not but are close get 1 and the player to get the farthest from the correct answer loses 1 token. ( Tokens are worth 1 point.)
Roles:
Player 1 ( Answers the questions.)
Player 2 ( Answers the questions.)
Player 3 ( Answers the questions.)
Player 4 ( Answers the questions.)
Question Master & Token Master ( Asks the questions and gives the token to the correct answer. )
How to Win:
Quick Match- Play until a player reaches 30 tokens.
Long Match- Play until all but one player is eliminated.
Ways to Lose- If a player loses all of there tokens or is cheating they are eliminated, this happens only when the player is caught cheating or stealing tokens from other players or when the player loses all of these tokens due to incorrect answers.
