The original price of the shorts is $35. They are on sale for 25% off. What is the sale price?
Answer:
$26.25
Step-by-step explanation:
So what you do is divide 25 by 100 so its a decimal .25 then multiply that by 35 and you get 35/4 or 8.75 you take that number and subtract it from 35 and you get 26.25.
For future reference what ever percentage you have like if says it went up 80% you divide that by a hundred also and you get .80 you multiply that by 35 you get 28 you don't subtract it from the original price but you add it so you get 35+28=63 and that's your final answer.
Remember you divide the percentage for example 25 by 100 multiply by the price it gives for example 35 if the question says off you subtract what you got from the original price if it went up you add it to the original price and that's your final answer. Hope this help :)

A: The absolute value of a number gives its distance from zero on the number line.
B: when you multiply either number by -1, you get the other.
C: The absolute value of a number always gives the opposite of a negative number in the square of a positive number.
D: when the numbers are squared, they give the same answer.
Answer:
The answer A. "The absolute value of a number gives its distance from zero on the number line."
Step-by-step explanation:
An absolute number has these in it '| |'. An absolute number always is positive, because it represents a difference.
For example, the difference of 0 and -30 is |30|.
Though 0 - 30 is -30, the DIFFERENCE is |30|.
As the answer says, "its distance from zero on the number line".
Final answer:
The absolute value of -9 equals the absolute value of 9, which is 9, because absolute value represents the distance from zero on the number line, and both -9 and 9 are 9 units away from zero, regardless of their direction.
Explanation:
The reason why |-9| = |9| is because the absolute value of a number refers to its distance from zero on the number line. This distance is always a non-negative number since it does not refer to direction, just the magnitude of separation from zero. Therefore, both -9 and 9 are 9 units away from zero, and their absolute values are equal.
In mathematical terms, the absolute value function, denoted by | |, strips away the sign of a number, turning any negative number into its positive counterpart. So, |9| is already positive, and |-9| transforms -9 into 9 because you remove the negative sign, rendering both absolute values equivalent.

Quinn has 6 bottles of water that each weigh 3/5 pound. What is the total weight of the water bottles? Use the number line to help
Answer:
The weight of 6 bottles = [tex]3\frac{3}{5}\ pounds[/tex] or [tex]3.6\ pounds[/tex]
Step-by-step explanation:
Given:
Total number of bottles = 6
Weight of each bottle = [tex]\frac{3}{5}[/tex] pound
To find the total weight of 6 bottles.
Solution:
We can plot the number line for six bottles.
We can the plot the weights in another number line.
Each unit represents [tex]\frac{3}{5}[/tex] pound of weight.
As the number of bottles increase the number of pounds of weight increase by [tex]\frac{3}{5}[/tex] .
Thus, weight of 6 bottles = [tex]\frac{3}{5}+\frac{3}{5}+\frac{3}{5}+\frac{3}{5}+\frac{3}{5}+\frac{3}{5}[/tex] [tex]=\frac{18}{5}[/tex] pounds
Converting fraction to mixed number.
[tex]\frac{18}{5}=3\frac{3}{5}[/tex] pounds
Or in decimals [tex]\frac{18}{5}=3.6\ pounds[/tex]
Thus weight of 6 bottles = [tex]3\frac{3}{5}\ pounds[/tex] or [tex]3.6\ pounds[/tex]

Answer:
The initial value of 600 is larger and larger by 24.
Step-by-step explanation:
First of all a 20% decreased of 600.
So, the new value will be [tex]600(1 - \frac{20}{100}) = 600 \times 0.8 = 480[/tex].
Now, then it is increased by 20% i.e. 480 will be increased by 20%.
So, the new value will be [tex]480(1 + \frac{20}{100}) = 480 \times 1.2 = 576[/tex].

If the difference between the 7th and 9th terms
of an arithmetic sequence is 25. Find the
Common difference.
The common difference is [tex]d=-\frac{25}{2}[/tex]
Explanation:
The difference between the 7th and 9th terms of an arithmetic sequence is 25
Since, we know the general form of an AP is [tex]a_{n}=a_{1}+(n-1) d[/tex]
For [tex]n=7[/tex], we have,
[tex]a_{7}=a_{1}+(7-1) d[/tex]
[tex]a_{7}=a_{1}+6 d[/tex] ---------(1)
For [tex]n=9[/tex], we have,
[tex]a_{9}=a_{1}+(9-1) d[/tex]
[tex]a_{9}=a_{1}+8 d[/tex] ----------(2)
Subtracting (1) and (2), we get,
[tex]a_7-a_9=6d-8d[/tex]
Since, it is given that the difference between 7th and 9th term is 25.
Hence, we have,
[tex]25=-2d[/tex]
Dividing both sides by -2, we have,
[tex]d=-\frac{25}{2}[/tex]
Hence, the common difference is [tex]d=-\frac{25}{2}[/tex]

Step-by-step explanation:
Hello! This is the answer.
Volume of a square pyramid:
V = (1/3)a2h
Slant Height of a square pyramid:
By the pythagorean theorem we know that
s2 = r2 + h2
since r = a/2
s2 = (1/4)a2 + h2, and
s = √(h2 + (1/4)a2)
This is also the height of a triangle side
Lateral Surface Area of a square pyramid (4 isosceles triangles):
For the isosceles triangle Area = (1/2)Base x Height. Our base is side length a and for this calculation our height for the triangle is slant height s. With 4 sides we need to multiply by 4.
L = 4 x (1/2)as = 2as = 2a√(h2 + (1/4)a2)
Squaring the 2 to get it back inside the radical,
L = a√(a2 + 4h2)
Base Surface Area of a square pyramid (square):
B = a2
Total Surface Area of a square pyramid:
A = L + B = a2 + a√(a2 + 4h2))
A = a(a + √(a2 + 4h2))
Therefore your answer is B 384.
