Choose the number in which the digit 2 is ten times greater than the digit 2 in 426.
Answer: 237
Step-by-step explanation:
Ok we can write 426 as:
400 + 20 + 6
Then the 2 in 426 is in the place of the tens and represents a 20.
If we want a number with a 2 that is 10 times greater than 20, we have that:
10*20 = 200.
Then we should find a number with a 2 in the hundreds place, an example can be:
237
where we can write this number as:
237 = 200 + 30 + 7
and the 2 is in the hundreds place.

Answer:
bro i dont get this but i bet the guy in top of me it is right in deed
Step-by-step explanation:
An item has a listed price of $80. If the sales tax rate is 7%, how much is the sales tax (in dollars)
Multiplying a listed price by the percent can get you the sales tax, and then you can add.
[tex]80*0.07=5.6[/tex]
(0.07 is 7% converted into a decimal)
[tex]80+5.6=85.60[/tex]
So the item is $85.60 after sales tax.
You may also notice that multiplying the listed price by 1.07 will get you the same answer, without the need to add the sales tax.
[tex]80*1.07=85.60[/tex]
Hope this helps.

Benito embroiders and sells T-shirts. The graph shows his profit as a function of the number of shirts sold. After selling a certain number of shirts, Benito uses some earnings to buy more materials and then increases the price of the shirts. Which of the following correctly compares the two parts of the function in Part A, over the intervals [0, 7] and [8, 11]? . . Benito made an extra $25 after selling 7 shirts. The price of one shirt increases from $10 to $15. Benito spent $1 after selling 50 shirts Benito's profit per shirt increases from $10 to $15.
Answer:
The correct option is;
Benito's profit per shirt increased from $10 to $15
Step-by-step explanation:
Over the interval [0, 7] from 0 to 7 on the x axis, we have;
At x = 0, y = -20, therefore the y-intercept = -20
At y = 0, x = 2 which is the x-intercept
The slope, m₁ of the straight line plotted dots on the interval from 0 to 7 on the x axis is found as follows;
m = (y₂ - y₁)/(x₂ - x₁)
m₁ = (0 - (-20))/(2 - 0) = 10
The equation of the interval is therefore;
y - 0 = 10×(x - 2)
y = 10·x - 20
Therefore, the profit, y increases by $10, for each shirt, x, sold over the interval from 0 to 7 on the x axis
Over the interval [8, 11] from 8 to 11 on the x axis, we have;
At x = 9, y = 40,
At x = 11, y = 70
The slope, m₂ of the straight line plotted dots on the interval from 8 to 11 on the x axis is found as follows;
m = (y₂ - y₁)/(x₂ - x₁)
m₂ = (70 - 40)/(11 - 2) = 15
The equation of the interval is therefore;
y - 70 = 15×(x - 11)
y = 15·x - 165
Therefore, the profit, y increases by $15, for each shirt, x, sold over the interval from 8 to 11 on the x axis.

pLEASE HELP ME I DONT UNderstande this at all
Answer:
Use this trick. PEMDAS.
P- parenthises. if there is something in the parenthises, you know you need to start with that first. Do the equatoin in the () parenthisis.
E- Exponents. If there is exponents in your equation, make sure you do them afteryou have done the steps in the parenthesis.
M- Multiply. Always multiply left to right. Always multiply after you have done the first two steps.
D- Divide. Divide the numbers left to right. Very simular to the multiplication.
A- Add. Always add left to right.
S- Subtract. Always subtract left to right.
------
Always do these steps in this order. If there is no addition, skip to subtraction.
Answer:
it's all about Order of Operations (lots of caveats here)
Step-by-step explanation:
These are exercises in the use of the Order of Operations.
The Order of Operations is a set of rules for how to evaluate an arithmetic expression. It tells you which operations to perform first, so that expressions like 1+2×3 are properly evaluated to 1+6 = 7, rather than incorrectly to 3×3 = 9, for example.
(Please be aware that some calculators do this incorrectly.)
__
In most cases involving numerical expressions, such as the ones shown, the rules are summarized by the mnemonics BEDMAS or BIDMAS or PEMDAS. The first two are more often used where British English is spoken. The meaning of these mnemonics is as follows:
B/P -- "brackets" or "parentheses". Expressions inside parentheses are evaluated first. Innermost parentheses are evaluated before enclosing parentheses. Your first expression shows an example of this:
4 ÷2 +5(10 -6)
has the expression (10 -6) evaluated first. The result is then the expression ...
4÷2 + 5×4
Note that in your last expression, the fraction bar effectively serves as parentheses for both the numerator and denominator. If this were written in plain text, it would be written as ...
(2^3 -5)/(15 +9)
__
E/I -- "exponents" or "indices". Anything with an exponent (index) is evaluated after parentheses are eliminated. Your second expression is an example of this:
(2+3)² first has the parentheses removed so you have
5²
Then the exponent is evaluated. Of course the exponent, or index, tells you how many times 5 is a factor in the product:
5·5 = 25
As with fraction bars, the typography of a typeset expression can imply grouping (parentheses). If the expression ...
[tex]2^{x+5}[/tex]
were written in plain text, it would have to be written with parentheses around the exponent:
2^(x+5)
__
D/M and M/D -- "division" and "multiplication". Here is where confusion may arise. Multiplication and division have the same priority, so are evaluated in the order they are found, left to right. The sequence of letters D or M in the mnemonic does not mean that one is performed before the other. Your first expression is an example of this:
4÷2 + 5×4 = 2 + 5×4 = 2 + 20
Here, the division happens to be first, so it is evaluated first. The multiplication is then evaluated second, because it appears to the right of the division.
__
AS -- "addition" and "subtraction". Again, confusion sometimes arises because the A appears before the S in the mnemonic. The operations of addition and subtraction have the same priority, so are evaluated in the order they are found, left to right.
_____
These are the rules. They can be modified somewhat by the properties of multiplication and addition when you actually perform the math.
For example, the expression 2×3×5 evaluated according to the rules would be = 6×5 = 30. However, we know that multiplication has associative and commutative properties, so we could evaluate this as 2×5×3 = 10×3 = 30. Similarly, we know that multiplication and division are inverse operations, so division by 2 is the same as multiplication by (1/2). Then we could evaluate ...
4÷2 = 4×0.5 = 2
This knowledge can let us rearrange an expression such as ...
5÷2×6 = 5×(1/2)×6 = 6×(1/2)×5 = 3×5 = 15
While this is a correct evaluation of the expression, you need to be careful. If your work is supposed to show an understanding of Order of Operations, you may be required to show your work as 5÷2×6 = 2.5×6 = 15.
_____
Additional comment on plain-text expressions
When in doubt, add parentheses around anything you want to consider to be a unit: numerators, denominators, exponents, fractions. Here's an example where grouping can be troublesome:
[tex]\boxed{9-3\div\dfrac{1}{3}+1} = 9-3\times3+1=9-9+1=0+1=1[/tex]
(division by 1/3 is the same as multiplication by 3/1)
When written in plain text, this is often written as ...
9 - 3 ÷ 1/3 + 1
which must be evaluated as ...
9 - 3/3 +1 = 9 -1 +1 = 9 . . . . . . the division 3÷1 is performed first
The key here is that 1/3 is intended to be treated as a fraction, so it needs to be in parentheses in plain text:
9 - 3 ÷ (1/3) + 1
This last example also shows that the order of operations treats ÷ and / and "over" and "divided by" as meaning the exact same thing: whatever is on the immediate left is divided by whatever is on the immediate right.* If that "whatever" is intended to be more than a single number or variable, it must be in parentheses.
__
* Yet another caveat: some authors consider "/" to always be a fraction bar, and ÷ to have the more conventional interpretation. Some authors consider ÷ to mean (everything to the left) divided by (everything to the right). The reason for the Order of Operations is to specify a standard interpretation of these symbols and their use.

Find the sum of 2x^2 - 6x - 2 and x^2 + 4x
Answer:
3x^2-2x-2
Step-by-step explanation:
2x^2 - 6x - 2 and x^2 + 4x
2x^2 - 6x - 2 +x^2 + 4x
Combine like terms
2x^2 +x^2- 6x + 4x- 2
3x^2 -2x -2
Based on the calculations, the sum of 2x² - 6x - 2 and x² + 4x is equal to 3x² - 2x - 2.
How to solve a quadratic equation?In Mathematics, the standard form of a quadratic equation is given by this mathematical expression:
ax² + bx + c = 0.
In this exercise, you're required to determine the sum of the given quadratic equations. Thus, we would add the equations together as follows:
2x² - 6x - 2 + x² + 4x
Combining like terms, we have:
2x² + x² + 4x - 6x - 2
3x² - 2x - 2

Answer:
Miss Meod lost $88 from Adams' first week of services.
Step-by-step explanation:
Assuming the first sentence stand
As Adams received $125 of wages the break-point is at $250 dollars
which is double of Adams' wage. Below this point the employe cannot realize a gain.
The services performed were $162 we subtract the break even point:
162 - 250 = -88
Durign the first week Miss Adams services generate a variable loss for $88
What is the equation of a line that is perpendicular to y = -1/5x + 1 and passes through point (0, -2)?
Answer:
y = 5x - 2
Step-by-step explanation:
The slope will be 5, because that is the opposite reciprocal of the original slope, -1/5
Then, plug the slope and the given point into y = mx + b to find b:
y = mx + b
-2 = 5(0) + b
-2 = 0 + b
-2 = b
Then, plug the y-intercept and the slope into the equation:
y = 5x - 2 will be the equation

Answer:
[tex]\dfrac{17}{30}[/tex] minutes.
Step-by-step explanation:
It is given that Sally takes [tex]2\dfrac{5}{6}[/tex] minutes to drive from her home to the local shopping center.
[tex]2\dfrac{5}{6}=\dfrac{2(6)+5}{6}[/tex]
[tex]2\dfrac{5}{6}=\dfrac{12+5}{6}[/tex]
[tex]2\dfrac{5}{6}=\dfrac{17}{6}[/tex]
She spends 1/5 of this time waiting at traffic lights.
Waiting time in traffic [tex]=\dfrac{17}{6}\times \dfrac{1}{5}[/tex]
[tex]=\dfrac{17}{30}[/tex]
Therefore, waiting time is [tex]\dfrac{17}{30}[/tex] minutes.
