Find the product for the following expressions:
(8c + 2)(5c-7)
Answer:40c^2-46c -14
Step-by-step explanation:
(8c+2)*(5c-7)
8c*(5c-7)+2(5c-7)
40c^2-56c+10c-14
40c^2-46c-14
Answer:
(8c + 2)(5c-7) = 40c²-46c-14Explanation:
(8c + 2)(5c-7) = 40c²-56c+10c-14
(8c + 2)(5c-7) = 40c²-46c-14

What is the median
Answer:
72 or 75
Step-by-step explanation:
If we are going in order then the median would be 72.
If we are going by what you posted, then it would be 75.
You were asking about the mean, so I though I would just add it in here.
So basically, the mean is just where you add up all the numbers, and then divide them by how many numbers you have.
For your problem, this is 39+87+72+88+75+87+15+53+53. This equals 569.
Now, lets count how many numbers we added: 1...2...3...4...5...6...7...8...9.
Ok, so lets divide the 569 by 9. This should get you 63.222...
That is your mean.

A painter sets a ladder
against a wall 9 ft above
the ground. If the ladder is
3 feet from the base of the
wall, how long is the ladder?
Round your answer
to the nearest tenth.
Answer: About 10 ft.
Use Pythagorean's Theorem!
c=[tex]\sqrt{9^2+3^2}[/tex]
9 * 9 = 81
3 * 3 = 9
81 + 9 = 90
[tex]\sqrt{90\\}[/tex] = 3[tex]\sqrt{10}[/tex] ≈ 10 ft.
Many places in Louisiana have a 10% sales tax. Talal buys a coat for $45 and has a 10% coupon that he uses. After that, he pays
the 10% sales tax. Calculate how much Talal pays for his coat after discount and tax.
Answer: $44.55
Step-by-step explanation:
$45 times the 10% sales tax equals $49.50
$49.50 minus the 10% discount equals $44.55
Discount 75%, Sale Price $74.75, Original Price-?
Answer:
You will pay $18.69 for a item
Step-by-step explanation:
if you buy an item at $74.75 with 75% discount, you will pay 74.75 - 56.0625 = 18.69 dollars.
Answer:
$299
Step-by-step explanation:
The discount is 75%, so the sale price represents 25% of the original price.
25% : $74.75
(multiply both sides by 4 to get 100%)
100% : $299

The first sequence rule is add 5 starting from 20. The second sequence rule is subtract 7 starting from 56. What is the first number that appears in both sequences?
25
28
42
35
Answer:
35
Step-by-step explanation:
The first number that appears in both sequences is 35.
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Now, The first sequence starts with 20 and adds 5 each time, so the first few terms are:
20, 25, 30, 35, 40, 45, 50, 55, 60, ...
And, The second sequence starts with 56 and subtracts 7 each time, so the first few terms are:
56, 49, 42, 35, 28, 21, 14, 7, 0, ...
Hence, Looking at these lists, we can see that the first number that appears in both sequences is 35.
This is the fifth term in the first sequence as,
⇒ 20 + 5 + 5 + 5 + 5 = 35
And, the fourth term in the second sequence is,
⇒ 56 - 7 - 7 - 7 - 7 = 35
Hence, the first number that appears in both sequences is 35.

A dress that is size x in France is equaivalent to size d(x) in the United States, where d(x)x32.
(a). Find a function that will convert U.S. dress size to French dress size.
(b) Use the inverse function to find the French size of a dress if it is U.S. size .
Answer:
[tex](a)\ d'(x) = x + 32[/tex] i.e. The inverse function
[tex](b)\ d'(10) = 42[/tex] i.e. The French size of a dress if it is U.S. size 10 is 42.
Step-by-step explanation:
Given
[tex]d(x) = x - 32[/tex]
Solving (a): The inverse function
[tex]d(x) = x - 32[/tex]
Replace d(x) with y
[tex]y = x - 32[/tex]
Swap y and x
[tex]x = y - 32[/tex]
Make y the subject
[tex]y = x + 32[/tex]
Replace y with d'(x)
[tex]d'(x) = x + 32[/tex]
Hence, the inverse function is: [tex]d'(x) = x + 32[/tex]
Solving (b): US size of 10
[tex]d'(x) = x + 32[/tex]
Substitute [tex]x =10[/tex]
[tex]d'(10) = 10 + 32[/tex]
[tex]d'(10) = 42[/tex]

Enter your answer, as an exact value, in the box.
Answer:
y=2√3, or 3.46410161513
Step-by-step explanation:
The smaller triangle is a right isosceles triangle, so the other side is also √2. To figure out it’s hypotenuse, you can use the Pythagorean theorem.
√2²+√2²=c²
2+2=c²
4=c²
√4=c
c=2
Now that we know that value, we can look at the bigger triangle. It is a 30-60-90 triangle, which has special properties.
Y would equal the two of the base times the square root of three.
y=2√3, or 3.46410161513
The value of the y is 2√3 if the value of hypotenuse in the triangle with 60-degree angles is 2
What is a right-angle triangle?It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
From the sin ratio in the triangle with angle 45 degree
Sin45 = √2/x
x = 2
From the triangle with angle 60 degree
y/2 = tan60
y = 2√3
Thus, the value of the y is 2√3 if the value of hypotenuse in the triangle with 60-degree angles is 2
