Need help with this final question.
$200 in the ratio 1:2:2 working out
Answer: 40:80:80
Step-by-step explanation:
The ratio is 1:2:2. This means, for every 5, the money is split in a ratio of 1:2:2. Let’s calculate how many 5s there are in 200. 200 / 5 = 40. So, the money will be split in 1:2:2 every 5 dollars 40 times.
Excellent. So, we can easily find out the ratio by multiplying the ratio 1:2:2 by 40. 1*40:2*40:2*40 = 40:80:80. Let’s add these up, and see if they result in 200. 40 + 80 + 80 = 200. So, our answer is correct.
Hope this helps!

help please! make sure to tell me the answer and an explanation!
Answer: 10
Step-by-step explanation:
So since this is all about perimeter you just got to add the values together. So lets use 12 as the denominator for every fraction. 1/4 is equal to 3/12 and 2/3 is equal to 8/12. So in conclusion 3/12 plus 8/12 and 1/12 will equal 1 in total. and then add up all the whole numbers 4 + 2 + 3 + 1 will get you 10. So 10 is your answer.

Solve the following quadratic function
by utilizing the square root method.
y = 100 – x2
Answer:
x = ± 10
Step-by-step explanation:
To solve the equation let y = 0 , that is
0 = 100 - x²( add x² to both sides )
x² = 100 (I take the square root of both sides )
x = ± [tex]\sqrt{100}[/tex] = ± 10
Then solution is x = - 10, x = 10

Please help urgent!!! Find the value of x in the triangle shown below!
Answer:
Step-by-step explanation:
so we know a few things about t his triangle, it's a special one :P , it's called isosceles because two of the legs are the same length, which also mean that the angle x is the same at the other unknown angle sooo there are 2 x's if that makes sense? and then we can solve this , b/c we also know that the interior angles of a triangle add up to 180°
180 = 32 + 2x
148 = 2x
74 =x
∠x = 74°

N Level 2017 1 Bryan is using a ladder which is 4.5 m long. He puts it against a wall so that the bottom of the ladder is 1.2 m from the wall. 4.5 1.2 The safe working angle for a ladder is between 74º and 76° to the horizontal. Is the ladder in a safe position for Bryan to use? Show the working on which you base your decision.
Answer:
133
Step-by-step explanation:
I am added all the degrees
Given:
Length of ladder = 4.5 meters
Length between ladder and wall = 1.2 meter
To find:
If the angle of the ladder is between 74° - 76°
Steps:
We know,
cos(x) = [tex]\frac{adjacent}{hypotenuse}[/tex]
Here 'x' is the angle of the ladder. Substituting the values,
[tex]cos(x) = \frac{1.2}{4.5}[/tex]
[tex]x = cos^{-1}(\frac{1.2}{4.5} )[/tex]
[tex]x = cos^{-1}(0.2666)[/tex]
Now we can either use natural cos table or use aa calculator, i am going to use the calculator but if you want to know how to do it with the table, pls comment to this answer.
x = 74.533°
Since x > 74° and x < 76°, it is safe for work
Therefore, the angle is in the safe position for Bryan to use

The table below shows some inputs and outputs of the invertible function f with domain all real numbers.
PLEASE HELP ME!!!!! ( photo given )
Answer:
-6, 0
Step-by-step explanation:
since the first question is a inverse function, the -15 isn't an x value anymore so it is a y.
the second question is the same thing for the 4 because it is an inverse function. so that would be -11, and the function of 9 you would look at the x value of 9 and find the corresponding y, which 11. so -11+11 =0
Solve the system of equations below by graphing both equations with a

A laptop computer has a regular price of $1,750. Today, people can purchase it with a 10% discount. What is the amount of the discount and the sale price of the laptop?
Discount:$
Sale price:$
Answer:
Sales price: $1,575 Discount: $175
Step-by-step explanation:
To find the sales price, you either multiply the percent(indecimals, so 10% would be .1) by the discount price, but be careful to subtract original by new.
To get the anwser right away, multiply the price you have to pay, 90%, so .9 by 1,750. You get $1,575.
To get the discount, subtract original by new, $1750-$1575=$175

Decide if the following scenario involves a permutation or combination. Then find the number of possibilities.
You are setting the combination on a five-digit lock. You want to use the numbers 12345 but you don't care what order they are in.
Answer:
It's a combination, BUT...
Step-by-step explanation:
Definition: A combination is a grouping of outcomes in which the order does not matter. That's the difference between combination and permutation.
Combination Formula: nCr = (n!)/[r!(n-r)!)] where n stands for number of things and r the pair chosen
Applied to this case: We have n=5 (12345) and r=5 for the 5-digit lock combination.
5C5 = (5!)/[5!(5-5)] = 1
But!! As you can see, we cannot have 1 possible combinations so.. We have to assume that this is a permutation!!! Conceptually, this looks pretty much like a combination, but being the same range as number of items, we conclude that it's a permutation.
Permutation Formula: nPr = (n!)/(n-r)!
nPr = (5!)/(5-5)! = 120
Well, this looks way more accurate now, right?
Final Answer: The scenario involves a permutation, and there's 120 possible combinations of those 5 numbers in a 5-digit lock.
