A store is having a clearance special and every item is 10% off. What is the sale price of a $210 suit?
Answer:
$189
Step-by-step explanation:
210 has to be multiplied by the decimal form of the percentage, 0.10, which equals to 21. This will be subtracted from 210, giving you an answer of $189.
Can you find four examples that are true or a counterexample for the following statement?For every integer n, the value of n^2 + 1 is odd
Solving the expression, it is found a counterexample that when [tex]n = 1[/tex], [tex]n^2 + 1 = 2[/tex] is even.
----------------------
The expression given is:[tex]E(n) = n^2 + 1[/tex]
We want to test for every integer n, that E(n) is odd.----------------------
For n = 0:
[tex]E(0) = 0^2 + 1 = 0 + 1 = 1[/tex]
Odd number.
----------------------
For n = 1:
[tex]E(1) = 1^2 + 1 = 1 + 1 = 2[/tex]
Even, thus, this is the counterexample.

we just need to rewrite 3x+2y+18=0 to look like that
We need to get y by itself
3x+18= -2y
we need y to be positive and to have no number in front of it (no coeficcent)
y= -3/2x-9
the slope is therefore -3/2

Step-by-step explanation:
3x + 2y + 18 = 0
Equating it with.

Given;
The figure of a right angle triangle.
To find:
The value of x.
Solution:
In a right angle triangle,
[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]
In the given right angle triangle,
[tex]\cos (45^\circ)=\dfrac{7}{x}[/tex]
[tex]\dfrac{1}{\sqrt{2}}=\dfrac{7}{x}[/tex] [tex][\because \cos (45^\circ)=\dfrac{1}{\sqrt{2}}][/tex]
On cross multiplication, we get
[tex]1\times x=7\times \sqrt{2}[/tex]
[tex]x=7\sqrt{2}[/tex]
Therefore, the value of x is [tex]7\sqrt{2}[/tex] units.

What is the value of 9 2/3 minus 4 1/5
Answer:
5 7/15 = D
Step-by-step explanation:
Find a common denominator multiply the many times you did to the denominator to the numerator then subtract.
15 is your common denominator so I would multiply 5 to 2 to get 9 10/15 then I would multiply 3 to 1 to get 4 3/15
Answer:
5 7/15
Step-by-step explanation:
Let's solve your equation step by step.
We will solve it in just 3 simple steps.
Step 1: Converting into Improper Fraction.
Converting into an Improper Fraction is the only way to subtract fractions.
We will turn 9 2/3 into 29/3
First you need to know:
What is a numerator?
What is a denominator?
What is a whole number?
If you know, you can skip this part.
A denominator is the lower number below the line in a fraction. (ex. 2/3 <-- "3" is the denominator)
A numerator is the higher number above the line in a fraction. (ex. 2/3 <---"2" is the numerator)
A whole number is a number that has no fraction or decimal. (ex. "3" or "2" or "7".)
With that said, let's solve.
In 9 2/3, "9" is the whole number. "2" is the numerator, and "3" is the denominator.
We always multiply the whole number by the denominator, then we add the numerator.
So:
(9 x 3) + 2 = 29
Then, we keep the denominator the same. "3".
We then get:
29/3. Which is what we want.
Let's repeat the same steps with 4 1/5.
(4 x 5) + 1 = 21
Keep the denominator : 21/5
Now we are on Step 2.
We currently have 29/3 - 21/5
But we don't have the denominators the same.
We need to find the LCD (Least Common Denominator of 3 and 5.
Since these numbers are less than 10, my trick is to just multiply them together. 3 x 5 = 15, simply put.
Now, let's change all the denominators to 15. Now let's change the numerators.
For the fraction that had 3 as the denominator, let's multiply 5 to it. And for the fraction that had 5 as the denominator, let's multiply 3 to it.
We then get :
145/15 - 63/15
We are now on Step 3.
This step is simple. Just subtract 145 - 63 because the denominators are the same.
145 - 63 = 82
We now have 82/15.
This is the answer, but we always need to simplify it.
How many times can 15 fit into 82? 5. But we have 7 left over.
So we now have :
5 7/15

Four friends shared 7 chocolate bars. Each of them was given an equal share of the chocolate bars. How many chocolate bars did each person get?
A: 4/7
B : 6/8
C: 1 1/4
D: 1 3/4
We are given:
There were 7 chocolate bars, evenly shared between 4 friends
Number of Bars one person will get:
Number of bars one person will get = Number of Bars / Number of Friends
Number of Bars = 7 / 4
but since this number does NOT match any of the given options, we will convert it to a mixed fraction
The number of bars one person will get will be [tex]1\frac{3}{4}[/tex], written as a mixed fraction.
Therefore, the correct answer is option D
Answer:
4 friends =7 chocolate
1 friend =7/4 chocolate =1 3/4 part of chocolate.

y= 5(x + 1)^2– 3
HELP!!!
Step-by-step explanation:
the answer is in the attachment
The graph of the function y= 5(x + 1)²– 3 is attached accordingly. See the description of the graph below.
The graph of y= 5(x + 1)²– 3The equation y = 5(x + 1)² - 3 represents a quadratic function.
The graph is a parabola with its vertex at (-1, -3). It opens upward since the coefficient of the squared term (x²) is positive.
The graph is vertically stretched by a factor of 5 compared to the standard quadratic function.
The x-coordinate of the vertex is -1, indicating a horizontal shift of 1 unit to the left from the standard quadratic.
