Simplify the following expression. Write the resulting polynomial in descending order.
–2x(1–3x) + (2x + 3)(3x – 2)
Answers
Answer: 4x² + x - 2
Step-by-step explanation: First distribute the -2x into (1-3x) which = -2x + 6x²
Now let's work on the second part:
Distributing (2x + 3) to (3x - 2) = 6x² - 4x + 9x - 6. Combining like terms: 6x² - 4x + 9x - 6 --> 6x² + 5x - 6. Now let's combine the like factors of our two equations which equals
12x² + 3x - 6. Now reduce by dividing by 3 which gives us the final answer of:
4x² + x - 2.

Elias bought 7 new shirts for school.
Five shirts cost $60.90. He also bought
a pair of pants for $14.99. Without tax,
what is the total amount Elias spent?
Answers
Answer:
$100.25
Step-by-step explanation:
This question says that 5 shirts cost $60.90, so you would divide the two numbers to find out the price of 1 shirt
$60.90÷5=$12.18
Then you would just solve this equation
T=$12.18x+$14.99
T= Total Money Spent
x= Number of Shirts
Plug in the 7 shirts and solve
T=$12.18(7)+$14.99
T=$85.26+$14.99
T=$100.25
Keith Hernandez has asked Jerry and Kramer to help him move into a new apartment on Sunday morning. He has asked them both in case one of them does not show up. From past experience, Keith knows that there is a 41% chance that Jerry will not show up and a 31% chance that Kramer will not show up. Even though Jerry and Kramer know each other, their decisions can be assumed to be independent.
a. What is the probability that both Jerry and Kramer will show up? (Round your answer to 2 decimal places.)
Probability
b. What is the probability that at least one of them will show up? (Round your answer to 2 decimal places.)
Probability
c. What is the probability that neither Jerry nor Kramer will show up? (Round your answer to 2 decimal places.)
Probability
Answers
Answer:
a. 0.41
b. 0.87
c. 0.13
Step-by-step explanation:
From the above question:
We are told that:
Probability that Jerry will not show up = 41% = 0.41
Probability that Jerry will show up =
100 - 41 = 59 = 0.59
Probability that Kramer will not show up = 31% = 0.31
Probability that Kramer will show up
= 100 - 31 = 69% = 0.69
Even though Jerry and Kramer know each other, their decisions can be assumed to be independent.
a. What is the probability that both Jerry and Kramer will show up? (Round your answer to 2 decimal places.)
= P(A) × P(B)
= Probability the Jerry will show up × Probability that Kramer will show up
= 0.69 × 0.59
= 0.4071
≈ 2 decimal places = 0.41
b. What is the probability that at least one of them will show up? (Round your answer to 2 decimal places.)
Probability = 1 - the probability that both Jerry and Kramer will not show up
= 1 - (0.41 × 0.31)
= 1 - 0.1271
= 0.8729
Approximately to 2 decimal places = 0.87
c. What is the probability that neither Jerry nor Kramer will show up? (Round your answer to 2 decimal places.)
Probability = Probability the Jerry will not show up × Probability that Kramer will not show up
= 0.41 × 0.31
= 0.1271
To 2 decimal places = 0.13
The Cooking Club made some pies to sell at a basketball game to raise money for the new math books. The cafeteria contributed four pies to the sale. Each pie was then cut into five pieces and sold. There was a total of 60 pieces to sell How many pies did the club make?
Answers
Answer:
the cooking club made 8 pies
Step-by-step explanation:
first do 60 divided by 5 to find the total number of pies you get 12
then since the cafetria donates four pies and the cooking club makes the rest, you do 12-4=8
There were 11 pies cooked in all by the club to earn money for the basketball game.
What is Function?
A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.
Given, The Cooking Club made some pies to sell at a basketball game to raise money for the new math books. The cafeteria contributed four pies to the sale.
Each Pie cut into four pieces
Since there were 60 pieces of pie
The total number of pies sell at a basketball game = 60/4
The total number of pies sell at a basketball game = 15
Also, given there were four pies donated by Cafeteria
Thus,
Total pie basketball team made = 15 - 4
Total pie basketball team made = 11
Therefore, the Total number of pies made by the club to raise funds for the basketball game is 11.

Find the mass of the object if it has a volume of 20 mL and a density of 3 g/mL.
Answers
Answer:
60 g
Step-by-step explanation:
Use the density formula, D = m/v, where m is the mass and v is volume
Plug in the volume and density, then solve for the mass:
D = m/v
3 = m/20
60 = m
So, the mass is 60 g
Volume of object = 20 mL
Density of object = 3 g/mL
To Find :We have to find mass of the object[tex].[/tex]
Solution :★ Density is defined as the mass of object per unit volume.
It is a scar quantity having only magnitude.
Mathematically, ρ = M/V
ρ denotes densityM denotes massV denotes volumeBy substituting the values, we get
⭆ 3 = M/20
⭆ M = 3 × 20
⭆ M = 60 g
∴ Mass of the object is 60g.

Answers
Answer:
each ticket is $8.75
Step-by-step explanation:

The equation that can be used to determine the cost of each movie ticket is C = $48.50 / 6.
What is the equation that can be used to determine the cost of each movie ticket?Total cost of the 6 movie tickets = (6 x cost of each ticket) - value of one coupon
50.50 = 6C - $2
Combine similar terms
$50.50 - $2 = 6C
$48.50 = 6C
Divide both sides of the equawtion by 6
C = $48.50 / 6

Answer: C.
Step-by-step explanation: You add all the numbers in A, B, C. Then look at which one has the lowest value.
A. is .97
B. is 1.01
C. . is .91
D. is .94
So C. has the lowest value
The number which has the lowest value is 0.23 +0.23 +0.45, the correct option is C.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Given;
A 0.30 +0.54 +0.13
B 0.10 +0.66 +0.25
C 0.23 +0.23 +0.45

A 0.30 +0.54 +0.13=0.97
B 0.10 +0.66 +0.25=1.01
C 0.23 +0.23 +0.45=0.91
0.30+ 0.41 +0.23=0.94

Answers
Answer:
Explained below.
Step-by-step explanation:
Denote the events as follows:
C = chess
V = volleyball
B = basketball
The data provided is as follows:
n (C) = 30
n (V) = 19
n (B) = 25
n (C ∩ V) = 14
n (B ∩ V) = 8
n (B ∩ C) = 15
n (C ∩ V ∩ B) = 5
Consider the Venn diagram below.
The number of students who played only chess is marked in pink:
n (Only C) = 6
The number of students who played only volleyball is marked in blue:
n (Only V) = 2
The number of students who played only basketball is marked in orange:
n (Only B) = 7
The number of students who played all three is marked in grey:
