Step-by-step explanation:
Radius of the circle = Diameter / 2 = 2cm.
Area = pi * (Radius)² = 4pi cm².
Answer:
4[tex]\pi[/tex]
Step-by-step explanation:
Radius is always half of the diameter.
So, 4/2=2
Now that we know the radius, we find the are.
The equation for area is [tex]\pi r^2[/tex]. When you insert everything, you get....
[tex]\pi[/tex][tex]*[/tex][tex]2^{2}[/tex]
When you put it all together, we get... 4[tex]\pi[/tex]

The Alvarado family went out for supper last week. The meal cost $65.92.
.
The sales tax is 7% of the meal.
The tip was 20% of the meal.
There are 4 people in the family.
What was the cost per person for the meal, including sales tax and tip?
A. $84.64
B. $21.16
C. $14.11
D. $16.48
The correct answer is $21.16
Explanation:
The first step to solve this mathematical problem and find the correct answer is to calculate the cost of the sales tax and the tip by using the cost of the meal. The process is shown below:
1. Calculate the sales tax (7%)
7% of $65.92
65.92 / 100 = 0.6592
0.6592 x 7 = 4.6144 (Money on the sales tax)
2. Now, add the initial cost of the meal to the taxes and calculate the tip (20%)
$65.92 + $4.6144 = $70.5344
20% of $70.5344
70.5344 / 100 = 0.705344
0.705344 x 20 = 14.10688 (Money on tip)
Now, let's add the three values to calculate the total cost of the meal
$65.92 + $4.6144 + $14.10688 = $84.64128
Finally, divide the price into 4 because 4 people will pay
$84.64128 / 4 = $21.16032 which can be simplified as $21.16

Answer:
200.96 ft^2
Step-by-step explanation:
A= πr^2. So the radius is 8, because it's half the diameter. That means A=64π. Then you multiply that to get 200.96, given that pi is estimated to 3.14.

Which conflict reaction involves a choice of whether or not to do something when part of the situation is attractive but the other is not? approach avoidance multiple approach approach approach avoidance avoidance
Answer:
Approach-avoidance
Step-by-step explanation:
The term that is being described in this question is known as Approach-avoidance. This occurs in many real-life scenarios where individuals really want something until they are met with the negative side of that goal and ultimately turn away because of those negative traits. One example that is widely used for this term is marriage. Marriage in itself is a very positive goal that many individuals strive for, but ultimately push away from it when they begin to see the negative aspects of it, even if the positive values overshadow the negative ones.
Kimberly is deciding between two cell phone plans. The first plan has a $50 sign-up
fee and costs $20 per month. The second plan has a $30 sign-up fee and costs $25 per
month. After how many months will the costs be the same for the two phone plans?
Answer:
2month and 2 weeks
Step-by-step explanation:
We are told that the first plan has a $50 sign-up
fee and costs $20 per month.
let the number of months be x, and the total cost be y
y=20x+50---------1
The second plan has a $30 sign-up fee and costs $25 per
let the number of months be x, and the total cost be y
y=30x+25---------2
Equate the two equations we have
20x+50=30x+25
solve for x, collect like terms
50-25=30x-20x
25=10x
divide both sides by 10
x= 25/10
x=2.5 months
x= 2month and 2 weeks

How many solutions does 8p + 1 = 4p +2 have?
Step-by-step explanation:
8p + 1 = 4p + 2
8p - 4p = 2 - 1
4p=1
4p/4p=1/4p
p=0.25
The equation 8p + 1 = 4p + 2 have one solution which is p = 0.25.
What is an Equation?Equations are mathematical statements where we write two expressions which is equal to each other. There will be a left hand side and a right hand side on either sides of an equation.
The main classes of equations in algebra are linear equations and polynomial equations. On these include quadratic equations, cubic equations, differential equations and so on.
We have the expressions 8p + 1 and 4p + 1 equal to each other.
8p + 1 = 4p + 2
Subtracting the term 4p on both sides, we get,
8p + 1 - 4p = 4p + 2 - 4p
4p + 1 = 2
Subtracting both sides with 1,we get,
4p + 1 - 1 = 2 - 1
4p = 1
Dividing both sides by 4, we get,
p = 1/4
p = 0.25
Hence there is one solution to the equation 8p + 1 = 4p + 2 which is p = 0.25.

Which of the following is true about the graph shown below?
A. The graph is not a function because it does not
start at (0,0).
B. The graph is a function because it passes the
vertical line test.
C. It is not a function because it is not linear.
D. It is a function because it has a constant rate of
change.
Answer:
B
Step-by-step explanation
A - the graph is a function and whether or not the graph starts at (0,0) does not say if it is a function
B - the graph is a function and the vertical line test does determine if a graph is a function
C the graph is a function and non-linear graphes can be functions
D - the graph is a function but the graph does not have a constant rate of change and a function can have a variable rate of change
Dilate the figure by a scale factor of 3.5. What are the verticals of the image?
Answer:
The vertices of the image are
J' (3.5, 14), K' (21, 14),
L' (21, 3.5), M' (3.5, 3.5) ⇒ D
Step-by-step explanation:
If the point (x, y) dilated by scale factor k and center the origin, then its image is the point (kx, ky)
In rectangle JKLM
∵ J = (1, 4), k = (6, 4), L = (6, 1) and M = (1, 1)
∵ The rectangle JKLM is dilated by a scale factor of 3.5
→ By using the rule above multiply each coordinate by 3.5
∴ J' = (1 × 3.5, 4 × 3.5) = (3.5, 14)
∴ K' = (6 × 3.5, 4 × 3.5) = (21, 14)
∴ L' = (6 × 3.5, 1 × 3.5) = (21, 3.5)
∴ M' = (1 × 3.5, 1 × 3.5) = (3.5, 3.5)
The vertices of the image are
J' (3.5, 14), K' (21, 14),
L' (21, 3.5), M' (3.5, 3.5)

After his initial reaction, Mr. Evil has some time to think. He calls you on the phone with a new plan. “OK,” he says. “I don’t need to be able to tunnel to the bank today, but I need to be able to do it within the next 30 years. I have access to a house that is much closer. I need to know if it will be close enough.” What do you need to know in order to answer him? Under what conditions would this new property be close enough to the bank????????? HELPPPPPPPPPPPPPPPPP
Answer:
um.
Step-by-step explanation:
So he is asking, abstractly, from lack of context, if his house is close enough to the bank?
This makes little sense, abstractly. I mean, does he live in a post-apocalyptic Mad Max setting where he needs explosives and men or perhaps a frozen-over world where he needs large steam-powered engines to drill through the permafrost? It makes little substantiated sense.
So you need to know how much money he has, his charisma level, and the setting of the plot.
If the property is next to the bank, then it would be, by far, close enough to the bank.

T= BA-9, for B
What does b=
9514 1404 393
Answer:
[tex]B=\dfrac{T+9}{A}[/tex]
Step-by-step explanation:
Add 9 to both sides of the equation, and divide by the coefficient of B.
T = BA -9
T +9 = BA
(T +9)/A = B
We can rewrite that with B on the left:
B = (T +9)/A
