Answer:
The original price was $312.50
Step-by-step explanation:
If the vacuum was marked down by 20%, that means it was sold for 80% of the full price. It was sold for $250, so 80% of the original price is $250.
Let's set up an equation.
80/100 of x = 250
0.8 • x = 250
Divide both sides by 0.8.
x = 312.50
The original price was $312.50
Hope this helps!
Answer:
I think the answer is 250.00
Step-by-step explanation:
Let the original price = x
Original Price - Markdown = Sales Price
x - (20%)x = $250
Note: 20% may be 0.20 or 20/100 as needed by the problem.
x - 0.20x = $250
0.80x = $250
x = $312.50
Check:
Is 312.50 - (0.20)312.50 = 250.00 ?
(0.80)(312.50) = 250.00 ?
250.00 = 250.00 ?yes

An aircraft flies at an average speed of 600 miles per hour. The expression 600t gives the distance traveled by the aircraft in t hours. Find the distance traveled by the aircraft in 6 hours. The distance traveled by the aircraft in 5 hours is:
Answer:
So, we know that the speed of the aircraft is 600 miles /per hour/. The question is, how many miles does it travel over 6 hours?
Since “per hour” means it travels that far in 1 hour, we need to take that speed (600mph) and multiply it by 6, since we were asked about the distance in 6 hours.
So:
600*6=3600
And we get a total of 3600 miles traveled in 6 hours, as opposed to 600 miles in 1 hour.

Alan rented a truck for one day. There was a base fee of $18.99, and there was an additional charge of 80 cents for each mile driven. Alan had to pay $239.79 when he returned the truck. For how many miles did he drive the truck?
Answer:
the number of miles did he drive the truck is 276 miles
Step-by-step explanation:
The computation of the number of miles did he drive the truck is as follows
Let us assume the mileage be m
Now according to the question
0.8m + 18.99 = 239.79
0.8m = 239.79 - 18.99
0.8m = 220.8
m = 276
Hence, the number of miles did he drive the truck is 276 miles
The above represent the linear equation

Answer:
208m²
Step-by-step explanation:
Okay, so you can split this abomination into a rectangle, another rectangle, and a square, so we're going to start with the rectangle to the far left:
The formula for the area of a rectangle or square is length x width, so we just have to plug:
4 x 8 = 32
Now we do the next rectangle, but we have to figure out the length first, so:
4 + 4 = 8
Now we plug:
8 x 4 = 32 (I now realize that the rectangles are even and we could've just multiplied the first one by two, but it's always good to check)
Now we do the square:
12 x 12 = 144
Now we add it all together:
32 + 32 + 144 = 208
So the area of the figure is 208m²
if this is wrong, let me know so I can fix it

The first term of an arithmetic sequence is 10 and its
common difference is -3. What is the sum of the first
10 terms of this sequence?
Please hurry! ill give brainliest
Answer:
The sum of the first ten terms is -35.
Step-by-step explanation:
The first term of an arithmetic sequence is 10, and its common difference is -3.
We want to find the sum of the first 10 terms of this sequence.
Remember that the sum for an arithmetic sequence is given by:
[tex]\displaystyle S=\frac{k}{2}\left(a+x_k\right)[/tex]
Where k is the number of terms, a is the initial/first term, and x_k is the last term.
Since our initial term is 10, a = 10.
And since we want to find the sum of the first ten terms, k = 10.
So, we will need to find the last or tenth term. We can write an explicit formula. The standard explicit formula for an arithmetic sequence is:
[tex]x_n=a+d(n-1)[/tex]
Where a is the initial term and d is the common difference.
So, by substituting, we acquire:
[tex]x_n=10-3(n-1)[/tex]
Then the tenth or last term is:
[tex]x_{10}=10-3(10-1)=10-3(9)=10-27= -17[/tex]
Then the sum of the first ten terms will be:
[tex]\displaystyle S_{10}=\frac{10}{2}(10+(-17))=5(-7)=-35[/tex]
Answer:
-35
Step-by-step explanation:
[tex]a_{1}[/tex] = 10+(-3)(0) = 10
[tex]a_{10}[/tex] = 10+(-3)(9) = -17
[tex]S_{10}[/tex] = 10[(10 -17)/2] = 10(-7/2) = -70/2

64th term of arithmetic sequence 29,38,47
Answer:
596
Step-by-step explanation:
Each term of the arithmetic sequence is 9 greater than the previous term.
Since the first term is 29, then 29+9 = 38, the second term in the sequence. Likewise, the third term, 47, is 9 greater than the previous term, 38. 47 is also 2(9) greater than the first term, 29.
Therefore, finding the 64th term in the sequence would be the same thing as adding 9 to the first term (29) a total of n-1, or 64-1 times. Instead of adding, one can simply multiply 29 by 63, since 64-1 = 63.
29 + 63(9)
= 29 + 567
= 596
So, the 64th term of the arithmetic sequence is 596.

Step-by-step explanation:
let 'x' = one number
let 'y' = other number
System of Equations:
x + y = 65
x - y = 41
Substitution Method:
x = 41 + y
41 + y + y = 65
2y = 24
y = 12
x + 12 = 65
x = 53
