Answer:
$100.70
Step-by-step explanation:
The difference between the total price ($434.50) and the sales price ($415) is the tax ($19.50). To find the sales tax as a percentage of the sales price, divide the sales tax by the sales price and then multiply by 100:

Step-by-step explanation:
Let's go through each answer choice.
The formula for Area of a rectangle is [tex]A=l*w[/tex]
a.
[tex]A=l*w=19*20=380\ ft^2[/tex]
b.
[tex]A=l*w=17*22=374\ ft^2[/tex]
c.
[tex]A=l*w=21*18=378\ ft^2[/tex]
d.
[tex]A=l*w=23*16=368\ ft^2[/tex]
Upon evaluation of each answer choice, we can conclude:
[tex]380 > 378 > 374 > 368[/tex]

Find the sum, if it exists, of the infinite geometric series = 102+112. 2+123. 42+…
Answer:
it does not exist
Step-by-step explanation:
if it is a geometric sequence, there must be a common ratio or multiplication factor between neighboring terms :
102 × r = 112.2
r = 112.2/102 = 1.1
is 112.2 × 1.1 = 123.42 ?
yes.
so, it is a geometric sequence with the common ratio of 1.1.
the problem is now : the ratio is > 1.
that means the sequence tends are growing, and growing, and the sum is therefore rather "exploding" than converging.
for the sum to converge to a specific number the individual terms need to get smaller and smaller in absolute numbers.
with r > 1 this is impossible, so there is no sum for this sequence (with n going to infinity, so does the sum, and as "infinity" is not a value per se, the sum does not exist).
Solve the following system of equations.
Answer:
n= -6, a= 5
Step-by-step explanation:
Label the two equations:
a= -2n -7 -----(1)
-3a +n= -21 -----(2)
Substitute (1) into (2):
-3(-2n -7) +n= -21
Expand:
-3(-2n) -3(-7) +n= -21
6n +21 +n= -21
Simplify, minus 21 on both sides:
7n= -21 -21
7n= -42
Divide both sides by 7:
n= -42 ÷7
n= -6
Substitute n= -6 into (1):
a= -2(-6) -7
a= 12 -7
a= 5

Write down the next two terms of this pattern :8,18,30,44,......
Answer:
60, 78
Step-by-step explanation:
To find a pattern, try experimenting.
Going from 8 to 18 is + 10
Going from 18 to 30 is + 12
Going from 30 to 44 is + 14
We see that we add 2 more extra than the term before (+10, +12, +14)
So, we just add 2 for the next 2 terms which will be +16 and + 18
which are 44 + 16 = 60
and 60 + 18 = 78
Answer:
im not sure but the pattern im seeing is adding by even numbers i could be wrong but I think the next two numbers are 60, and 78
Step-by-step explanation:
8 + 10 is 18
18+ 12 is 30
30 +14 is 44
so i did
44+16 and got 60
and 60 + 18 is 78.

Answer:
two situations in which a person or business might use probability to make a decision
1. Weather Forecasting
2. Sales Forecasting
explanation
Weather Forecasting : the individual might question themselves about what the weather is gonna look like the day . is it gonna rain ? should I bring an umbrella ? should i take the car to work just incase it starts raining , or should I walk on foot and enjoy the hot sun?
Many retailers use probability to forecast the possibility of selling a specific amount of products on a given day, week, or month. This allows companies to forecast how much stock they will require in the future. A company, for example, may use a forecast model that claims it has a 90% chance of selling at least 100 items on a given day. To avoid running out of items to sell, keep at least 100 (preferably more) on hand at all times.

Explanation:
Divide the horizontal sides to get
image/preimage = B'C'/BC = 15/10 = 1.5 = 1 & 1/2
This says that the larger image's side lengths are 1.5 = 1 & 1/2 times that of the corresponding preimage side lengths.

Two sides of the rectangle differ by 3. 5 cm find the dimension of the rectangle if its perimetre is 67cm
Answer:
Step-by-step explanation:
Two sides of the rectangle differ by 3.5 cm means that one side is 3.5 cm more than the other side.
If width = x cm, then length = x + 3.5
Perimeter = 67 m
2*(length +width) = 67
2*(x + 3.5 + x) = 67
2*(2x + 3.5) = 67
2*2x + 2*3.5 = 67
4x + 7 = 67
4x = 67 - 7
4x = 60
x = 60/4
x = 15 cm
Width = 15 cm
Length = 15 + 3.5
= 18.5 cm

mr castle shares out 56 marbles between emily and asif in the ratio of 7:1 how many does each child get?
Answer:
Emily = 49
Asif = 7
Step-by-step explanation:
Let's take the number of marbles given to asif = x
Then, the marbles got by Emily will be 7 times that of asif 7x
Then,
7x + 1x = 56
8x = 56
x = 56/8
x = 7
So, number of marble asif got = x = 7
And number of marbles Emily got = 7x = 7 * 7 = 49

How would you explain the differences between graphing x > 4 and x ≥ 4 to a peer who missed this lesson?
Answer:
x > 4 you would graph with an open circle and x ≥ 4 you would graph with a closed circle. The question x is greater than or equal to 4 you would have the line going to the right, the same thing with x > 4. Hope this helped.

HELP ITS MAKING ME DO ANOTHER ONE
Answer:
Since we know that each of the three triplets are the same age we can put next to n, 3.
And given that another child is 14 years old we can put that next to the "+" sign.
In total, it would equal 32, so put the 32 after the equal sign.
It should look like this:
3n + 14 = 32
But now they want us to solve for the triplet's ages, so we just solve for n;
3n + 14 = 32
-14 -14
3n = 18
/3 /3
n = 6, the triplet's ages are 6 years old each.
Oliver completed his project in no more than twice the amount of time it took Karissa to complete her project. Oliver spent 4 and one-fourth hours on his project. If k represents the amount of time that it took Karissa to complete her project, which inequality can be used to represent the situation? 4 and one-fourth less-than 2 k 4 and one-fourth less-than-or-equal-to 2 k 4 and one-fourth greater-than 2 k 4 and one-fourth greater-than-or-equal-to 2 k.
The time taken by Oliver to complete the work is less than or equal to twice the work done by Karissa.
Option B shows the correct equation of inequality to write the time taken to complete the work.
What is inequality?Inequality can be defined as a relation that makes a non-equal comparison between two numbers or other mathematical expressions.
Given that Oliver completed his project in no more than twice the amount of time it took Karissa to complete her project. Also, the time taken to complete the project is,
Oliver = 4 and one-fourth hours
Karissa = K hours
As per the given condition, the work done by Oliver should not be more than twice the work done by Karissa. It can be equal or less. So we can write this in equation form as,
Oliver [tex]\leq[/tex] 2 Karissa
[tex]4\dfrac {1}{4} \leq 2K[/tex]
Hence Option B shows the correct equation of inequality to write the time taken to complete the work.

Your sock drawer has two white socks, six brown socks, and six black
socks. You randomly pick a sock and put it on your left foot and then pick
another sock and put it on your right foot. You leave the house with a white
sock on your left foot and a brown sock on your right foot. *
Answer
The probability of this occurring is 1/7
Step-by-step explanation:
Okay, here is a probability question.
From the question, we can identify the following;
Total number of socks = 2 + 4 + 2 = 8 socks
Since we are not given the order in which the socks was worn, we can assume any order.
Let’s say the right leg socks was worn first.
From the question, the socks on the right leg is a brown one.
So now let’s calculate the probability of selecting a brown socks out of the mix
That would be ;
number of brown socks/ total number of socks = 4/8 = 1/2
Now, for the left foot, we are having white sock here.
Kindly recall that since we already have a sock on the right foot, we have 7 socks left to pick from.
Now we need the probability of picking a white sock from the total 7. That would be ; 2/7
So the probability of both action occurring is simply the product of both probabilities and that is ;
1/2 * 2/7 = 1/7
Find the circumference of the circle. You must show all work to get full credit. Don't forget to label your answer. Round to the nearest hundredth.
Answer:
The circumference is 26.38 yards
Step-by-step explanation:
The formula for finding the circumference of a circle is 2π(r). 2 times pi times the radius. We see that the radius is 4.2 yards, so we plug 4.2 into the variable labeled "r"
2 (3.14) (4.2) = 26.376
26.376 rounded to the hundredths place is 26.38
