09 - 31 = 0
0 +5=6
2x + 4 = 10
09-1=4
51 - 7 = 1
3x + 1 = 9
Answer:
2x + 4 = 10 = x =3
Step-by-step explanation:
09 - 31 = 0 (the variable x is not present in the given system)
0 +5=6 (the variable x is not present in the given system)
2x + 4 = 10 = x = 3
09-1=4 (the variable x is not present in the given system)
51 - 7 = 1 (the variable x is not present in the given system)
3x + 1 = 9 = x = 8/3

While running for class president, Amanda handed out a campaign button. The catalog from which the button was ordered states that it has a circumference of 12.56 inches. What is the button's area?
Answer:
A = 12.554 square inches
Step-by-step explanation:
Let's start with the formulas:
Circumference = [tex]2\pi r[/tex]; Area = [tex]\pi r^{2}[/tex]
We can use the circumference to find the radius, r, which we need for the area
12.56 = [tex]2\pi r[/tex]
Isolating r gives us [tex]\frac{12.56}{2\pi } = r[/tex]
A = [tex]\pi (\frac{12.56}{2\pi })^{2}[/tex]
Solving gives us 12.554, which you can further round if necessary.

What is an equation of the line that passes through the points (-1, 4) and (1, -6)?
Answer: y=-5x-1
Step-by-step explanation:
The two given points are (-1,4) and (1.-6)
We can then use the slope formula (Y2-Y1)/(X2-X1) to find the slope
4-(-6)/ -1-1 = 10/-2 = -5
Slope is -5
We then plug the slope in a set of points to find the y intercept
-5*-1+x = 4
5+x=4
x=-1
Then just add these two together to form the equation of y=mx+b
y=-5x-1

Kym plans to deposit $100 in an account at the end of each month for the next five years so that she can take a trip. (a) If Kym's opportunity cost rate is 6 percent compounded monthly, how much will she have in the account in five years? (b) How much will be in the account if the deposits are made at the beginning of each month?
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Monthly deposit= $100
Interest rate= 0.06/12= 0.005
Number of periods= 12*5= 60 months
a)
To calculate the future value, we need to use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit
FV= {100*[(1.005^60) - 1]} / 0.005
FV= $6,977
b) If the deposit is at the beginning of the month, the interest is compounded one more period. We need to use the following formula:
FV= {A*[(1+i)^n-1]}/i + {[A*(1+i)^n]-A}
FV= 6,977 + {[100*(1.005^60)] - 100}
FV= 6,977 + 35
FV= $7,012

Claire flips a coin 4 times. Using the table, what is the probability that the coin will show tails at least once?
A 2-column table with 5 rows. Column 1 is labeled number of tails with entries 0, 1, 2, 3, 4. Column 2 is labeled probability with entries 0. 06, 0. 25, question mark, 0. 25, 0. 6.
0. 06
0. 25
0. 69
0. 94
Answer: 0.94
Step-by-step explanation:
The required probability of getting at least one tail is given as 0.94. Option D is correct.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
The probability of getting tails at least one time is given as,
P(T) = 1 - P(T)'
From the given table.
P(T) = 1 - 0.06
P(T) = 0.94
Thus, the required probability of getting at least one tail is given as 0.94. Option D is correct.

Answer: They report paying an average of about $87 per night for lodging on their domestic trips, and just a dollar or two more per night when traveling abroad. Overall, Americans spend an average of $33 per day on food when on a vacation within the U.S. In aggregate, more than 80% of that amount is spent in restaurants.
Step-by-step explanation: An estimate of what the average person spends on vacation is approximately $205-$305 per day plus transportation costs. This is based on spending $150-$250 a night on your accommodations and $60 a day on meals.
Dan buys a car for £2700.
It depreciates at a rate of 1.4% per year.
How much will it be worth in 5 years?
Answer:
The car will be worth £2516.22 in 5 years
Step-by-step explanation:
The rule of depreciating is
[tex]A=P(1-r)^{t}[/tex], where
A is the new valueP is the original valuer is the rate in decimalt is the time in years∵ Dan buys a car for £2700
∴ P = 2700
∵ It depreciates at a rate of 1.4% per year
∴ r = 1.4% = 1.4/100 = 0.014
∵ We need to find how much it will be worth in 5 years
∴ t = 5
→ Substitute all of these values in the rule above to find A
∵ [tex]A=2700(1-0.014)^{5}[/tex]
→ Use your calculator to find the answer
∴ A = 2516.22
∴ The car will be worth £2516.22 in 5 years

You're planning to place an order from an online boutique. Leggings cost $12 each and shipping is a flat rate of $5. If your total was $41, how many pairs of leggings did you buy?
The pairs of legging purchased is 3
How to determine the number of leggings?Let the number of leggings be x.
The cost per legging is given as:
$12
So, the total amount is:
Total = 12x
The flat rate is given as:
Flat rate = 5
So, we have:
Total = 12x + 5
Your total is $41
So, we have:
12x + 5 = 41
Subtract 5 from both sides
12x = 36
Divide through by 12
x = 3
Hence, the pairs of legging purchased is 3

Often, there is more than one set of sequences that will take a preimage to an image. Determine one or two other sequences to create FGHIJ from ABCDE.
Hello.
The minimum number of rigid transformations required to show that polygon ABCDE is congruent to polygon FGHIJ is 2 (translation and rotation).
A rotation translation must be used to make the two polygons coincide.
A sequence of transformations of polygon ABCDE such that ABCDE does not coincide with polygon FGHIJ is a translation 2 units down and a 90° counterclockwise rotation about point D
Have a nice day
Answer:
FGHIJ: Dilate ABCDE with respect to the origin by a scale factor of 0.5, and then rotate the image 180° clockwise about point (0, 2). Translate the image 1 unit down and 7 units to the right.
FGHIJ: Reflect ABCDE across the x-axis, and then reflect the image across the y-axis (or vice versa). Dilate the image with respect to the origin by a scale factor of 0.5. Translate the image 3 units up and 7 units to the right.
Two similar triangles have a pair of
corresponding sides of length 12 meters and 8
meters. The larger triangle has an area of 180
square meters. Find the area of the smaller triangle.
Answer:
The area of the smaller triangle is 80m²
Step-by-step explanation:
Find the scale factor to get the dimensions of the smaller triangle from the larger triangle using the given information:
[tex]\frac{\text{Large Triangle Length}}{\text{Small Triangle Length}}=\frac{12}{8}=\frac{3}{2}[/tex]
When scaling the area of similar shapes, we will square the scale factor for the lengths. We do this because area is a 2-dimensional measurement.
[tex](\frac{3}{2})^2=\frac{9}{4}[/tex]
Let x represent the area of the smaller triangle. So, we have:
[tex]\frac{9}{4}=\frac{180}{x}[/tex]
Cross multiply:
[tex]9x=4(180)[/tex]
[tex]9x=270[/tex]
Divide by 9:
[tex]x=\frac{720}{9}[/tex]
[tex]x=80[/tex]
Therefore, the area of the smaller triangle is [tex]80m^2[/tex].

At an arcade, there is a machine that accepts game tokens and returns tickets
that can be redeemed for prizes. Inserting 5 tokens returns 3 tickets and
inserting 10 tokens returns 8 tickets. You must insert tokens in multiples of 5 or
10, and you have a total of 20 tokens. Identify the domain in this situation?
*
Answer: 5, 10, 15, 20
Step-by-step explanation:
Domain is all possible values that can be used as inputs in a function.
The arcade machine accepts multiples of 5 game tokens. You have 20 tokens. As the machine accepts 5 game tokens, the minimum is 5. Since you have 20, the maximum is 20.
The multiples of 5 are:
5 x 1 = 5
5 x 2 = 10
5 x 3 = 15
5 x 4 = 20
