Dillon pays x dollars to get a haircut. He gives the stylist a
20% tip. The expression representing his total cost is
X + 0.2x.
Vhich expression is equivalent and why?
A. 1.02x, because adding 20% to the cost of the haircut is the same
as multiplying the cost by 1.02.
B. x(0.2), because the cost of the haircut can be factored out.
O C. 1.2x, because adding 20% to the cost of the haircut is the same as
multiplying the cost by 1.2.
D. 1.2x, because adding $20 to the haircut is the same as multiplying
the cost by 1.2
Answers
Answer:
C. 1.2x
Step-by-step explanation:
He pays 1 x for his haircut, and an additional 20% on top of that, or an additional 0.2x. If you write that as an expression, you can simplify it like this:
[tex]1x+0.2x\\1.2x[/tex]
You can also work it out by multiplying by 1.2 as stated in answer C. If his haircut costs $10, adding a 20% tip of $2 is the same as multiplying by 1.2.
[tex]10\times1.2=12[/tex]

What is the percent increase of 24 to 32?
Answers
Answer:
8%???????????????????????
I will show you how calculate the Percent Change from 24 to 32.
Basically, we are trying to find the change from 24 to 32 in terms of percent. We do this in three steps:
1) Find the difference between 24 and 32 as a number.
2) Divide the result from Step 1 by the starting number 24.
3) Multiply the result from Step 2 by 100 to get it in terms of percent.
The three steps above can be made into a formula. So, to find the percent change from 24 to 32, we use this formula:
((Y-X)/X)*100 = Percent Change
X is the starting number 24, and Y is the ending number 32 that it changed to. When we enter these numbers into the formula, we get:
((32-24)/24)*100 = 33.33%
So, the answer to the question "What is the Percent Change from 24 to 32?" is:
33.33%
Note: All percent answers are rounded to the nearest two decimals if necessary.

Step-by-step explanation:
This is Finite Math, I got this hehe :)
To find the answer, first you need to understand what R means.
It stands for "row". So R1 means "Row 1".
So: -3R1 + R3 means that you need to multiply -3 by all of the numbers in row 1 and then add all of the numbers in row 3
[0 3 1 -1 l 6]
[0 1 -1 -7 l 0]
[3 0 -2 2 l 12]
[4 1 5 3 l 7]
Then use ^^THAT^^ and apply the next set of instructions.
-4R1 + R4 means that you multiply -4 by all of the numbers in row 1 and then add all of the numbers in row 4:
[4 -11 1 7 l -17]
[0 1 -1 -7 l 0]
[3 0 -2 2 l 12]
[4 1 5 3 l 7]

23% of a snack mix is almonds. How much snack mix would you need to get 230g of almonds?
Answers
Answer:
230/p = 23/100 You would need 1,000 g of snack mix.
Step-by-step explanation:
There are 1000 snack mix would be needed to get 230g of almonds.
Given that;
23% of a snack mix is almonds.
And, there are 230g of almonds.
Let us assume that;
The number of snacks = x
Hence, it can be written as,
23% of x = 230
23/100 × x = 230
23x = 23000
x = 23000/23
x = 1000
Therefore, The number of snacks = 1000 g

If we express $3x^2 - 6x - 2$ in the form $a(x - h)^2 + k$, then what is $a + h + k$?
Answers
If we express [tex]3x^2-6x-2[/tex] in the form [tex]a(x-h)^2+k[/tex], then a + h + k = -1
The given quadratic expression is:
[tex]3x^2-6x-2[/tex]
To express [tex]3x^2-6x-2[/tex] in the form [tex]a(x-h)^2+k[/tex], follow the steps below
Rewrite [tex]3x^2-6x-2[/tex] as [tex]3x^2-6x+3-5[/tex]
Factorize common terms
[tex]3(x^2-2x+1)-5[/tex]
This can be further simplified as:
[tex]3(x-1)^2-5[/tex]
Therefore, the vertex form of the equation [tex]3x^2-6x-2[/tex] is [tex]3(x-1)^2-5[/tex]
Compare [tex]3(x-1)^2-5[/tex] with [tex]a(x-h)^2+k[/tex]
a = 3, h = 1, k = -5
a + h + k = 3 + 1 - 5
a + h + k = -1
Therefore if we express [tex]3x^2-6x-2[/tex] in the form [tex]a(x-h)^2+k[/tex], then a + h + k = -1

Step-by-step explanation:
(y - y1)/(x - x1) = (y1 - y2)/(x1 - x2)
(y - 4)/(x - (-3)) = (4 - (-1))/(-3 -2)
(y - 4)/(x + 3) = 5/-5

Darla ran 1/2 mile. Laura ran 5/8 mile. How many miles did they run altogether?
Answers
Answer:
1 1/8 mile
Step-by-step explanation:
when it says altogether most of the time you're supposed to add.
When you add fractions you need to have both denominator (number below the line) be the same. and sense 1/2 and 4/8 are equal we will replace it.
you add the numerators (top numbers) and keep the denominator (bottom number)
[tex]\frac{4}{8} + \frac{5}{8} = \frac{9}{8} =1\frac{1}{8}[/tex]
Sense the numerator is bigger you subtract the bottom number from the top number and put a 1 in front of the fraction.

there are five bells which ring at interval of 4,5,12 and 15 minutes respectively at what minute those bells ring at the same time?
Answers
=====================================================
Explanation:
Let's find the LCM of 4 and 5, which are the first two items of the list.
multiples of 4 are: 4,8,12,16,20,24,...multiples of 5 are: 5,10,15,20,25,...The smallest item in each list is 20, so the LCM of 4 and 5 is 20.
We can replace the "4,5" in the list "4,5,12,15" with "20". So our new list would be "20,12,15".
We then repeat the process of finding the LCM of the first two items
multiples of 20 are: 20,40,60,80,...multiples of 12 are: 12,24,36,48,60,72,...LCM of 20 and 12 is 60.
The list "20,12,15" condenses to "60,15".
Repeat this process of finding the LCM once more and you'll find the overall LCM is 60.
Therefore, the LCM of the entire set {4,5,12,15} is 60. This is the smallest multiple shared by all four values. Interestingly enough, the outer values pair up to multiply to 60, and so do the inner values.
4*15 = 60
5*12 = 60
The bells ring together every 60 minutes
In other words, all of the bells ring together at the same time every hour (perhaps at the top of every hour; eg at 7:00 pm and at 8:00 pm, etc).
