Answer:
$9,450.00
Step-by-step explanation:
to take sales tax, you convert the % into a decimal ( in this case 5% is equal to 0.05) and multiply that by the cost of the product:
9,000 x 0.05 = 450
that is the amount that you pay in tax. In order to get the entire total add that amount to the original price:
9,000 + 450 = 9,450
2 step equations that equal 18
Answer:
(2x6)+6
2x6=12
12+6=18
Final answer:
Two-step equations that equal 18 can be solved by performing two operations to isolate the variable, such as subtracting and then dividing, or adding and then dividing.
Explanation:
A student is asking for examples of two-step equations that result in an answer of 18. Two-step equations involve performing two operations to solve for the unknown variable. For instance, a simple two-step equation could be x/2 + 5 = 14, where you would first subtract 5 from both sides to get x/2 = 9, and then multiply both sides by 2 to find x = 18.
Another example could be 2x - 4 = 32. To solve this equation, you would first add 4 to both sides, resulting in 2x = 36, and then divide both sides by 2 to get x = 18.
These examples help students understand how to manipulate equations using addition, subtraction, multiplication, or division to isolate the variable and solve the equation.
If f(n) = n2 - 2n, which of the following options are correct? Select all that apply. f(2) = 0 f(1) = 3 f(-4) = 24 f(5) = 35 f(-2) = 0
Answer:
f(2)=0
f(-4)=24
Step-by-step explanation:
We are given
f(n)=n^2-2n
We are asked which of the following are true?
f(2)=0
f(1)=3
f(-4)=24
f(5)=35
f(-2)=0
Let's start with f(2)=0.
f(2)=2^2-2(2)
f(2)=4-4
f(2)=0
So f(2)=0 is true.
Moving on to f(1)=3.
f(1)=1^2-2(1)
f(1)=1-2
f(1)=-1
So f(1)=3 is false.
Now for f(-4)=24.
f(-4)=(-4)^2-2(-4)
f(-4)=16+8
f(-4)=24
So f(-4)=24 is true.
f(5)=35?
f(5)=5^2-2(5)
f(5)=25-10
f(5)=15
So f(5)=35 is false.
Finally f(-2)=0.
f(-2)=(-2)^2-2(-2)
f(-2)=4+4
f(-2)=8
So f(-2)=0 is false.
Answer:
The correct option are,
f(2) = 0, and f(-4) = 24
Step-by-step explanation:
Given function,
[tex]f(n) = n^2 - 2n[/tex]
By substituting n = 2,
[tex]f(2) = 2^2 - 2(2) = 4 - 4 = 0[/tex]
By substituting n = 1,
[tex]f(1) = 1^2 - 2(1) = 1 - 2 = -1[/tex]
By substituting n = -4,
[tex]f(-4) = (-4)^2 - 2(-4) = 16 + 8 = 24[/tex]
By substituting n = 5,
[tex]f(5) = (5)^2 - 2(5) = 25 - 10 = 15[/tex]
By substituting n = -2,
[tex]f(-2) = (-2)^2 - 2(-2) = 4 + 4= 8[/tex]
This year a small business had a total revenue of $26,00 if this is 33% more than their total revenue the previous year. what was their total revenue of the previous year
Answer:
19,549
Step-by-step explanation:
If 26,000 ( I'll assume you missed a 0) is 33% more than their total the previous year.
If the previous year is supposed to be 100%, this year is 100% + 33% = 133%
Using rule of three:
26,000 -> 133%
x -> 100%
x = 100/133 * 26,000 = 19,549
0.9333 as a fraction
Answer:
0.9333 as a fraction equals 9333/10000
Step-by-step explanation:
0.9333 = 0.9333/1 = 9.333/10 = 93.33/100 = 933.3/1000 = 9333/10000

Tom has been a customer of the same bank foe two years and his income can change frommonth to month after paying bills. Tom places 250.00 a month in a two year CD. He notices that last year twice he withdrew 250.00 from his CD early to pay monthly bills. His bank charges a penalty for a early CD withdraw. His bank requires a minimum of 150.00 for regular savings accounts 750.00 for money markets, and 1,000 for CDs what would be the best strategy
Tom's best strategy would be to keep a minimum balance of $1,000 in his CD to meet his bank minimum requirement.
What is Tom's best strategy?From the given information, Tom's income can change from month to month and he needs to withdraw money from his CD to pay monthly bills, he should plan ahead and withdraw the necessary amount in one go to minimize the number of early withdrawals.
Withdrawing $250.00 from his CD every month for bills would result in multiple early withdrawals, incurring multiple penalties.
Thus, Tom's best strategy would be to keep a minimum balance of $1,000 in a separate CD for longer-term savings and avoid multiple early withdrawals.
Also he should keep the majority of his funds in a regular savings account or money market account for more flexibility in managing his irregular income and monthly expenses.

A. -4
B. -3
C. 4
D. 6
E. -6
F. 18
Answer:
D
Step-by-step explanation:
Given
6x² - 2x + 36 = 5x² + 10x ( subtract 5x² + 10x from both sides )
x² - 12x + 36 = 0 ← in standard form
(x - 6)² = 0 ← in factored form, thus

The lengths of the sides of a triangle are 3, 3, 3 square root 2 Can the triangle be a right triangle?
The triangle can be a right triangle according to the Pythagorean theorem.
Explanation:To determine if a triangle is a right triangle, we can use the Pythagorean theorem. According to the Pythagorean theorem, in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (hypotenuse).
In this case, the lengths of the sides are 3, 3, and 3√2. Let's calculate: (3)² + (3)² = 18 and (3√2)² = 18. Since the two values are equal, the triangle satisfies the Pythagorean theorem and can be a right triangle.

[tex][/tex]An ice cream sundae costs $1.75 plus an additional $0.35 for each topping. If the total
cost is $2.80, how many toppings did the sundae have?
Answer:
3
Step-by-step explanation:
$1.75 (ice cream) + $0.35 (topping) * x (some toppings) = $2.80, so I can rewrite it like that: 1.75+0.35x=2.80
1) Move the constant to the right side and change its sign: 0.35x=2.8-1.75
2) Substract the numbers: 0.35x=1.05
3) Divide the both sides of the equation by 0.35
4) x=3
"The correct number of toppings on the sundae is 3.
To solve the problem, we first establish the cost of the ice cream sundae without any toppings, which is given as $1.75. We also know that each topping costs an additional $0.35. The total cost of the sundae with toppings is $2.80.
Let's denote the number of toppings as \( t \). The total cost of the sundae with toppings can be represented by the equation:
[tex]\[ \text{Total cost} = \text{Cost of sundae} + (\text{Cost per topping} \times t) \][/tex]
Substituting the known values into the equation, we get:
[tex]\[ 2.80 = 1.75 + (0.35 \times t) \][/tex]
To find the number of toppings [tex]\( t \)[/tex], we need to isolate [tex]\( t \)[/tex] on one side of the equation. We do this by subtracting the cost of the sundae from both sides of the equation:
[tex]\[ 2.80 - 1.75 = 0.35 \times t \][/tex]
[tex]\[ 1.05 = 0.35 \times t \][/tex]
Now, we divide both sides of the equation by the cost per topping to solve for [tex]\( t \)[/tex]:
[tex]\[ \frac{1.05}{0.35} = t \][/tex]
[tex]\[ t = 3 \][/tex]

To make orange paint, Roger next 5/8 cup of red paint to his cup of yellow paint. He really likes of the resulting color and wants to make a large batch of the orange paint. How much yellow paint is needed to mix with one cup of red paint?
Answer:
It is needed [tex]\frac{8}{5}[/tex] cups of yellow paint to mix with one cup
of red paint
Step-by-step explanation:
* Lets explain how to solve the problem
- To make the orange pint, Roger mixed 5/8 cup of red paint to one
cup of yellow paint
∴ The ratio of red paint to yellow paint is 5/8 : 1
- Lets simplify it by multiplying the two terms of the ratio by 8
∵ [tex]\frac{5}{8}(8):1(8)[/tex]
∴ The ratio of red paint : yellow paint = 5 : 8
∴ For every 5 cups of red paint we need 8 cups of yellow paint to
make the orange paint
- We need to know how many yellow paint is needed to mix with
one cup of red paint
∵ red paint : yellow paint
5 : 8
1 : ?
- By using cross multiplication we can find the number of yellow cups
∴ The number of the yellow cups = [tex]\frac{1*8}{5}=\frac{8}{5}[/tex]
∴ It is needed [tex]\frac{8}{5}[/tex] cups of yellow paint to mix with one
