The question lacks the appropriate diagram. Find the diagram attached.
The triangle is a right angled triangle that is made of of three sides namely the opposite, the adjacent and the hypotenuse (the longest side). According to the diagram, the longest side is the side with length x. To get the side length x, we will use the Pythagoras theorem as shown;
hyp² = opp²+adj²
hyp² = 33²+56²
x² = 1089+3136
x² = 4225
take the square root of both sides
√x² = √4225
x = 65
Hence the unknown side length x is 65
Find the LCM and HCF.
(a) p3 + 8 and p2 - 4
Answer:
In bold below.
Step-by-step explanation:
p^2 - 4 = (p - 2)(p + 2)
Note that 8 = 2^3 so
p^3 + 8 = ( p + 2)(p^2 + 4 - 2p)
So The HCF is p + 2.
The LCM = (p + 2)(p - 2)(p^2 + 4 - 2p)

During its first year in business, Alice's restaurant shows a loss of $12,000. During its second year, the restaurant makes a profit of $23,200, and during its third year, the restaurant shows a loss of $1,200. What is the net profit of the restaurant during its first three years in business?
Answer:
$10,000
Step-by-step explanation:
-12,000+23,200-1,200= 10,000
The profit of the restaurant during it's first 3 years is 9800 dollars.
What is profit and loss ?When the amount of money we get is more than what we have invested is more we have profit and when the amount of money we get is less than what we have invested we have loss.
Let us assume Alice start with a net profit or or of 0 dollars.
During its first year in business, Alice's restaurant shows a loss of 12,000 dollars.
∴ He is in loss of (0 - 12000) dollars which is
= - 12000 dollars.
During its second year, the restaurant makes a profit of 23200 dollars.
∴ His net profit is
= ( -12000 + 23000 ) dollars.
= 11000 dollars.
During its third year, the restaurant shows a loss of 1200 dollars so his ne profit is
= ( 11000 - 1200 ) dollars
= 9800 dollars.

Jamie invests part of $10,000 at 9% annual interest and the rest at 8%. If his annual income from
these investments is $860, how much does he invest at 8%?
Answer:
$4000
Step-by-step explanation:
Assuming a = money invested at 9%
Assuming b = money invested at 8%
then we can form am equation from the question given
1) a + b = $10000, also
0.09a + 0.08b = $860 -> multiply by 100
2) 9a + 8b = $86000
Next we try to solve both equations simultaneously. We multiply both the left hand side and the right hand side of the first equation by 8. We have
3) 8a + 8b = $80000, now we subtract 3 from 2
9a + 8b = $86000
-8a - 8b = -$80000
a = $6000.
Then, we plug this in any of the first 2 equations, to get b
9 * $6000 + 8b = $86000
$54000 + 8b = $86000
8b = $86000 - $54000
8b = $32000
b = $32000/8
b = $4000.
Therefore, he invested $4000 at 8%
Consider the composite function (g (x) ) = StartRoot StartFraction 1 Over x squared minus 3 EndFraction EndRoot. If g(x) = x2 – 3, what is f(x)?
Answer:
C ON EDGE 2020
The function f(x) = [tex]\sqrt{1/x}[/tex] if, F[g(x)] = [tex]\sqrt{(1/x^2 - 3)}[/tex], g(x) = x² - 3, so option C is correct.
What is a function?
The function is a relationship between a set of potential outputs and a set of possible inputs, where each input has a single relationship with each output. This means that if an object x is present in the set of inputs (also known as the domain), then a function f will map that object to exactly one object f(x) in the set of potential outputs (called the co-domain).
Given:
F[g(x)] = [tex]\sqrt{(1/x^2 - 3)}[/tex]
g(x) = x² - 3
Put the value of g(x) in all the options and check whether it is equal to F[g(x)] as shown below,
Put it in option 3,
f{g(x)} = [tex]\sqrt{(1/x^2-3)}[/tex]
Thus, f(x) = [tex]\sqrt{1/x}[/tex]

3. Two fair dice are thrown once, find the probability of getting a total score greater than 5
Answer:
26/36
Step-by-step explanation:
The probability of something = the amount of favourable outcomes/total possible outcomes.
The total number of dice combinations is 36 (6x6).
In this case there are more outcomes more than 5 than less than 5 so for the sake of simplicity we are going to find the number of outcomes less than 5 and then find the inverse.
There are only 10 possible dice combos which add to totals 5 or under:
1,1 1,2 2,1 1,3 3,1 1,4 4,1 2,2 2,3 and 3,2
That means there is a 10/36 probability of getting a total score less than 5 so to get the probability of getting more than 5, we just do 36/36 - 10/36 (because all probabilities add to 1)
Therefore there is a 26/36 probability that the toatals will add to greater than 5.
Alternatively you could also draw up a possibilities table and count the favourable outcomes.
Hope this helped!
Answer:
13/18.
Step-by-step explanation:
The favourable outcomes are (1,5) (1,6) (2,4) (2,5) (2,6) (3,3) (3,4) (3,5) (3,6) (4,2)(4,3) (4,4) 4,5) (4,6) 5,1) (5,2) 5,3) (5,4) (5,5) (5,6 )(6,1) to (6,6).
= total of 26.
As the total of all possible outcomes is 36 the answer is 26/36
= 13/18.

The average cost of an item is defined as the total cost to produce divided by the number produced.A shoe company that pays $240,000 in rent and employee salaries per year figures it also must pay $3.50 in materials per shoe set it produces Write the equation needed to solve the problem. Use the equation to find the number of shoe sets the company would need to produce for the average cost of each set to be $7.50. Work out the problem, show all of your steps, and provide explanations.
Answer:
Step-by-step explanation:
Average cost = Total cost to produce / number of items produced
Fixed cost per year = $240,000
Variable cost = $3.50s
Where s = number of shoes produced
Total cost= fixed cost + variable cost
Total cost = $240,000 + $3.50s
When average cost = $7.50
Average cost = Total cost to produce / number of items produced
7.50 = $240,000 + $3.50s / s
Cross product
7.50s = $240,000 + $3.50s
Collect like terms
7.50s - 3.50s = 240,000
4s = 240,000
divide both sides by 4
s = 240,000 / 4
= 80,000
s = 80,000

If the ratio of boys to girls at the school is 2:5 and there are 40 boys how many girls are there?
Answer:
100 girls
Step-by-step explanation:
The ratio of boys : girls is 2 : 5.
In other words, boys are 2 parts of the school while girls are 5 parts of the school.
Since there are 40 boys, 2 parts of the school is 40. Thus:
[tex]2p = 40\\p = 20[/tex]
1 part is 20.
Since there are 5 parts girls, there are
[tex]5p = 5*20 = 100[/tex]
100 girls.
Answer: 100 girls
The total number of students in school is 140 and number of girls at the school is equal to 100.
What do you mean by ratio ?
Ratio is the quantitative relationship between two values indicating how frequently one value contains or is contained within the other.
It is given that the ratio of boys to girls at the school is 2:5.
Let's assume the total number of students in school is x.
We now need to find the number of girls in the school but before that we must try to find the total number of students in the school.
Sum of ratios = 2 + 5 = 7
It is given that there are 40 boys in students.
2/7 of the total number of students are boys.
i.e., the expression can be written as :
2x / 7 = 40
2x = 40 × 7
2x = 280
x = 140
The total number of students in school is 140.
So , the number of girls in school is :
= 140 - 40
= 100
There are 100 girls in the school.
Therefore , the total number of students in school is 140 and number of girls at the school is equal to 100.

Sally hopes to buy a 10 - kayak for $15,000. Describe all the numbers that when round to the nearest hundred are 15,000
Answer:
All the numbers ranging from 14,500 to 15444 would be rounded to 15000
Step-by-step explanation:
All the numbers ranging from 14,500 to 15444 would be rounded to 15000.
How this is possible.
1) all the numbers from 0-4 are not counted as the next number when rounded off.
2) all the numbers from 5-9 are counted as the next number when rounded off.
Example Suppose we have numbers from 15- 19.
These numbers can be rounded off to 20
But numbers from 10-14 would never be rounded off to 20 instead they are rounded as 10.
Same happens in the hundreds case.
If we have numbers from 450 - 499 they can be rounded as 500
And numbers from 400 - 444 cannot be rounded as 500 but the number 445 may be rounded as 450 . When we carry 5 from units place and replace it as 450 then again 450 can be rounded to 500.
Same happens with 15000 but when are rounding nearest hundred not ten.
Thus all the numbers ranging from 14,500 to 15444 would be rounded to 15000.
You are trying to estimate the average amount a family spends on food during a year. In the past the standard deviation of the amount a family has spent on food during a year has been approximately $900. If you want to be 99% sure that you have estimated average family food expenditures within $50, how many families do you need to survey? Round your answer up to the nearest whole number, if necessary.
Answer:
the number of families needed for the survey is 2,157
Step-by-step explanation:
The computation of the number of families needed for the survey is shown below:
Given that
The Standard deviation is $900
Service level = 99%
z value at 99% = 2.58
Expenditures = $50
Based on the above information
The number of families needed for the survey is
[tex]n = (\frac{zs}{E})^2\\\\= (\frac{2.58\times 900}{50})^2[/tex]
= 2,157
Hence, the number of families needed for the survey is 2,157
