Answer: $8.97
Step-by-step explanation:
he bought three jars and lowered the price by 75 cents for each, so multiply $0.75 by three
$0.75 * 3 = $2.25
so henri saved $2.25 in total
we can add that to what he paid to find the original cost
$6.72 + $2.25 = $8.97
so the original price was $8.97 :)

Rose and her twin brother decided to carry their juice in the lunch bags. Rose choose the tin juice that holds 472ml. Her brother took the bottled juice that contains 1/2 litre. Which of the two had more juice and by how much?
Answer:
Her brother had more juice by 28 mL
Step-by-step explanation:
Convert the 1/2 liter bottle to mL.
In 1 liter, there are 1000 mL. So, in 1/2 liters, there are 500 mL.
Since Rose's tin juice only holds 472 mL, her brother had more juice.
Find how much more he had by finding the difference:
500 - 472
= 28
So, her brother had more juice by 28 mL

The 3 real roots of the given equation.
To find the real roots.
What is quadratic equation?Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power. The quadratic formula to solve a quadratic equation ax2 + bx + c = 0 is x = [-b ± √(b2 - 4ac)]/2a.
Given that:
The equation are

The area of a rectangular painting is 5049 cm. If the width of the painting is 51 cm, what is its
length?
Answer:
The length is 99 centimeters.
Step-by-step explanation:
The area of a rectangle is found by multiplying:
A = Length • width
We also know that the area of the rectangular painting is 5,049 cm^2
An equation to represent this is:
51w = 5049
To find w, divide:
5049/51 = 99
CHECK YOUR ANSWER:
Formula tor area of a rectangle:
Length x width
Use formula with the measurements:
99 x 52 = 5049
So the length is 99 centimeters.

The salesman has observed that many students are looking for cars that cost less than $5,000. If he decides to also deal in cars that cost less than $5,000 and projects selling 200 of them over the next 10 years, how will the distribution be affected? A. The mean will shift to the right. B. The mean and the median will be the same. C. The median will shift to the right. D. The mean will shift to the left.
Answer:
D. The mean will shift to the left.
Step-by-step explanation:
Given that the price range of the car is between $5000 and $45000 ;
Hence, if the demand for cars that cost less than $5000 is in high demand, such that about 200 cars was sold ; This will lead to a shift in the mean price of car, $5000 towards the $5000 value. Since $5000 is to the left, then the mean price will shift to the left of the distribution.

find the area of 72 by 108 inches in square yards? pls show work
Step-by-step explanation:
72 times 108 = 7776 sq inches
to convert inches to yds divide by 36
7776/ 36 = 216 sq yds
Answer: 6 yards^2
Step-by-step explanation:
first lets find the area of the space in inches and then convert the total to square yards :)
area = length * width
A = 108 * 72 = 7776 inches^2
now lets convert it
there are 1296 inches in a yard, so we divide 7776 by 1296 to find the number of square yards
7776 / 1296 = 6
so the area of the space is 6 yards^2
What are the solutions to the equation (2x+1)^2-(x+13)=3x^2-2x+2
The second term in a sequence is 13. The term to term rule is "add 6"
Write an expression, in terms of n, for the nth term of the sequence.
Answer:
[tex]a_{n}[/tex] = 6n + 1
Step-by-step explanation:
This is an arithmetic sequence with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 13 - 6 = 7 and d = 6 , then
[tex]a_{n}[/tex] = 7 + 6(n - 1) = 7 + 6n - 6 = 6n + 1
Answer:
the first few terms would be
7, 13, 19, 25, 31
nth term = 7 + 6(n+1)
nth term = 7+ 6n + 6
nth term = 6n + 13
