Answer:
4.50 i think
Step-by-step explanation:
a product that normally costs $25 with a 18 percent discount will cost you $20.50, and you saved $4.50. You can also calculate how much you save by simply moving the period in 18.00 percent two spaces to the left, and then multiply the result by $25 as follows: $25 x . 18 = $4.50 savings.
Answer:
4.5
Step-by-step explanation:
you multiply 18 and 25 to get an answer of 450 then divided it by 100 to get 4.50
The parabola has focus (–8, 0) and vertex at the origin
Answer:
x = -1/32y^2
Step-by-step explanation:
Since the focus is to the left of the vertex at a distance of 8 units, the equation can be written as ...
x -h = 1/(4p)(y -k)^2 . . . . with vertex-focus distance of p and vertex (h, k)
x = -1/32y^2
Two rental car companies are running specials this month. At Johnson's Rentals, customers will pay $50 to rent a mid-sized car for the first day, plus $2 for each additional day (x). At Martinez Rent-a-Car, the price for a mid-sized car is $30 for the first day and $4 for each additional day (x). How many additional days (x) would it cost the same to rent from either company? What is that cost?
Answer:
If we rent the same car from both companies it would take 8 days
Step-by-step explanation:
Johnson's 50+2x
Martinez 30+4x
a) [tex]10[/tex] additional days are required for both to cost the same.
b) The cost is [tex]70[/tex]$.
At Johan's Rental:
Rent[tex]=(50+2x)[/tex]$
At Martinez Rent:
Rent[tex]=(30+4x)[/tex]$
For both the cost same
[tex]50+2x=30+4x[/tex]
[tex]2x-4x=30-50[/tex]
[tex]-2x=-20[/tex]
[tex]x=10[/tex]
[tex]\therefore[/tex] [tex]10[/tex] additional days are required for both to cost the same.
Cost[tex]=(50+2x)[/tex]
[tex]=50+2\times 10[/tex]
[tex]=50+20[/tex]
[tex]=70[/tex]

What is a quadratic function?A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.
Given:
g(x) = 2x² - 4
The above function is a quadratic function.
The solution of when g(-2):
Substituting the value of x = -2
g(x) = 2x² - 4
g(x) = 2(-2)² - 4
g(x) = 8 - 4
g(x) = 4
Therefore, the value of g(-2) = 4.

Problem Ari thinks the perfect milkshake has 333 ounces of caramel for every 555 scoops of ice cream. Freeze Zone makes batches of milkshakes with 666 ounces of caramel and 888 scoops of ice cream. What will Ari think about Freeze Zone's milkshakes
Answer:
That their milkshakes need more caramel or less ice cream.
Step-by-step explanation:
We can see that Ari's numbers for a perfect milkshake gives us a caramel to ice cream ratio of 333 / 555 = 0,6.
But the Freeze Zone uses a caramel to ice cream ratio of 666 / 888 which is equal to 0,75.
Their milkshakes have less caramel and more ice cream than Ari's perfect milkshake so Ari will think that Freeze Zone's milkshakes are not sweet enough.

5/6 divided by 1/7 this is dividing fractions
Answer:
35/6
Step-by-step explanation:
The result of dividing 5/6 by 1/7 is 35/6.
Here, we have,
To divide fractions, we can use the following rule:
To divide one fraction by another, we multiply the first fraction by the reciprocal of the second fraction.
In this case, we have:
(5/6) ÷ (1/7)
To find the reciprocal of a fraction, we simply flip the fraction by swapping the numerator and denominator.
Therefore, the reciprocal of 1/7 is 7/1.
Now, we can rewrite the expression as a multiplication:
(5/6) * (7/1)
Multiplying the numerators and denominators:
(5 * 7) / (6 * 1)
Simplifying:
35/6
Therefore, the result of dividing 5/6 by 1/7 is 35/6.
