176.3- 15.75
Answer:
I have that same question on my extra credit!
Step-by-step explanation:
I know the answer its 160.55 but I don't know what i should do for the problem. This is my questions:
Mina asked four friends to explain how each one solved the expression . Here are their explanations Please comment if these are the same:
Ivy’s explanation: I lined up the numbers to subtract.
176.3
- 15.75
18.8
Hannah’s explanation: I lined up the two decimals according to place value. I put a 0 in the hundredths place to make it easier for me to subtract.
176.30
- 15.75_
161.45
Jose’s explanation: I lined up the two decimals according to place value.
176.3
- 15.75
161.45
An’s explanation: I counted up from 15.75 to 176.3 to find the difference. I underlined each number I added on each line.
15.75 + 0.25 = 16
16 + 4 = 20
20 + 150 = 170
170 + 6 = 176
176 + 0.3 = 176.3
I rearranged the underlined numbers to make them easier to add: .
150 + 6 + 3 + 0.25 = 163.25
Explain each student’s mistake and solve the problem correctly.

Answer:
Step-by-step explanation:
A local park currently has 150.04 square meters of grassy area. The members of a community group have proposed the following
changes to the way the park land is used
• Clearing dead trees and shrubs would allow for 37 51 square meters of additional grassy area.
• Removing an unused picnic pavilion would allow for 82.70 square meters of additional grassy area.
• Updating and expanding the playground would reduce the grassy area by 54 19 square meters
How many square meters of grassy area would the park have if all of the community group's proposals were applied?
Answer: they would have 216.06 square meters of grassy area left in the park
Step-by-step explanation: if you start with 150.04 and add 37.51 by removing trees and shrubs you would have 187.55 and then if you added 82.70 more square feet by removing the unused Picnic pavilion you would have 270.25 square meters of grassy area. Then lastly is you update the playground by reducing 54.19 square meters ( 270.25-54.19) you would get left with 216.06 square meters of grassy area :)

Problem 16-05 To generate leads for new business, Gustin Investment Services offers free financial planning seminars at major hotels in Southwest Florida. Gustin conducts seminars for groups of 25 individuals. Each seminar costs Gustin $3300, and the average first-year commission for each new account opened is $5100. Gustin estimates that for each individual attending the seminar, there is a 0.01 probability that he/she will open a new account. Determine the equation for computing Gustin’s profit per seminar, given values of the relevant parameters. Round your answers to the nearest dollar. Profit = (New Accounts Opened × $ 5100 ) – $ 3300 What type of random variable is the number of new accounts opened
Answer:
1) The equation for computing Gustin's profit per seminar is given as follows;
The profit = (The number of Newly Opened Accounts) × Commission - Seminar cost
2) The number of new accounts is a continuous random variable
Step-by-step explanation:
1) The number of individuals that attend each of Gustin's seminar = 25 individuals
The cost of each seminar = $3,300
On average the commission on the first-year for each opened account = $5,100
The probability of opening an account by an attendee of each seminar = 0.01
The profit = Revenue - The cost of each seminar
The revenue = (The number of Newly Opened Accounts) × (Commission on each account)
∴ The revenue = (The number of Newly Opened Accounts) × $5100
Therefore, the equation for finding Gustin's profit per seminar is given as follows;
The profit = (The number of Newly Opened Accounts) × Commission - Seminar cost
The profit = (The number of Newly Opened Accounts) × $5100 - $3,300
The number of Newly Opened Accounts = (The number of attendee) × (The probability of an attendee opening an account)
The number of Newly Opened Accounts = 25 × 0.01 = 0.25
The number of Newly Opened Accounts = 0.25
The profit = 0.25 × $5100 - $3,300
The revenue = 0.25 × $5100 = $1,275
The profit = $1,275 - $5,100 = -$3,825 = ($3,825)
2) The number of Newly Opened Accounts = 0.25 which gives, that Gustin has to conduct 4 seminars to be sure of 1 new account, which represents a probabilistic variable which is the definition of a continuous random variable.
Therefore, the number of new accounts is a continuous random variable.

Can you please help me solve this and show the solution 4y⁴+6y?
Answer:
4y^4 + 6y = 256y + 6 = 262y
Step-by-step explanation:
Remove the variables for a second and think of the problem as a normal expression; 4^4 + 6
Simplify the first term; 4^4 = 256
Now, add 6; 256 + 6 = 262
Add back in the variable; 262y
Answer:
2y(2y+3)
Step-by-step explanation:
2y(2y) +6y factor 2y out of 4y^2
2y(2y)+2y(3) factor 2y out of 6y
2y(2y + 3) factor 2y out of 2y(2y)+2y(3)
Barbara, Becky and Beth dressed up as princesses for
Halloween. One was Snow White. One was Sleeping
Beauty. One was Cinderella. Becky is not Sleeping
Beauty and she went trick-or-treating with Snow White.
Beth and Sleeping Beauty are sisters. Who is Snow
White?
Answer:
The answer is Beth.
Step-by-step explanation:
It states "Becky is not Sleeping Beauty and went trick-or-treating with Snow White" so we know that its not Becky. It also states "Beth and Sleeping Beauty are sisters" so we know that Beth is not Sleeping Beauty and we know that Becky is not Sleeping Beauty or Snow White. So it means that Barbara is Sleeping Beauty, Becky is Cinderella and Beth is Snow White.

Answer:
p=9 m=21 x= - 30
Step-by-step explanation:
p=9
m=21
x= - 30
Step-by-step explanation:
1) 3p + 5 = 14
3p = 14 - 5
3p = 9
p = 9/3
⇢ p = 3
2)
m/7 - 3 = 0
m/7 = 3
m = 3 × 7
⇢ m = 21
3) 8 + x/2 = -7
x/2 = -7 - 8
x/2 = - 15
⇢ x = -30
A coordinate grid with 2 lines. The first line is labeled f(x) and passes through (negative 4, 3), (0, 3) and (4, 3). The second line is labeled g(x) and passes through the points (negative 2, negative 5), (0, negative 2), and (2, 1)
Determine the input value for which the statement
f(x) = g(x) is true.
From the graph, the input value is approximately (2) (2.5) (3.5) or (4)

I know this is hard I'm sorry ;-;
Answer:
A
Step-by-step explanation:
hi! this is modus ponens. modus ponens is a form of assumption, and modus tollens denies the initial statement. modus ponens is like saying if A, then B occurs as well. if A is proven to be true, B must also be true. this makes sense in this situation because it says if an animal is a dog, then it barks (if A, then B). the animal barks, so it is a dog (A is true, so B must also be true).

Answer:
3x + 2 = 14
3x + 2 - 2 = 14 - 2
3x = 12
3x/3 = 12/3
x = 4
Step-by-step explanation:
3x + 2 = 14
subtract 2 from both sides
3x + 2 - 2 = 14 - 2
combine like terms.
3x = 12
divide both sides by 3
3x/3 = 12/3
x = 4
The value of w varies directly with z. If z = 4, then w = 12. What is the value
of w when z = 6? (TEKS: A2D)
Answer:
18
Step-by-step explanation:
w varies directly with z, let k be the constant of proportionality, hence this can be represented by the equation:
w = kz
When z = 4, w = 12, hence we need to find the value of the constant of proportionality, substituting:
12 = 4k
Dividing both sides by 4:
12/4 = 4k/4
k = 3
Therefore the equation becomes:
w = 3z
The value of w when z = 6 is given as:
w = 3(6)
w = 18

Help asappp , What is the slope of a line perpendicular to the line whose equation is
3x + 6y = –18. Fully reduced
Answer:
2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + 6y = - 18 ( subtract 3x from both sides )
6y = - 3x - 18 ( divide all terms by 6 )
y = - [tex]\frac{1}{2}[/tex] x - 3 ← in slope- intercept form
with slope m = - [tex]\frac{1}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2
Slope of the line perpendicular to given line 3x + 6y = –18 is 2
What is slope intercept form and relation between slopes of two perpendicular lines ?The slope intercept of a line is given : y = m x+ c
y is y coordinate, x is x coordinate, m is the slope of the line
c is y- intercept of the line
If given that the slope of two lines are m₁ and m₂ then these lines are perpendicular, if the product of their slopes is -1 or m₁ *m₂ = -1
Given line is 3x + 6y = –18
Subtract 3x from both sides
⇒ 3x +6y -3x = -3x-18
⇒ 6y = -3x-18
⇒ y =(-3/6)x -18 /6 = (-1/2) x -3
comparing it with slope intercept , slope = -1/2
let the slope of line perpendicular to given line is m
then m.(-1/2) = -1
⇒ m = 2
∴Slope of the line perpendicular to given line is 2
