Answer:

Area = 131.9167322

Step-by-step explanation:

I'm not sure what 2 DP means so you will need to do that part.

area=pi*radius^2

area=3.14*42 (approx)

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

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

Answer:

2x^2 + 8xy - 2y^2

Step-by-step explanation:

2X(X+y) + 2y(3X-y)

2x^2 + 2xy + 6yx - 2y^2

2x^2 + 8xy - 2y^2

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°

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

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!

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.

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

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.

Answer:

B & C

Step-by-step explanation:

Mixture B:

4 white 2 red

Mixture C:

Divide the whole paint combinations by 2:

2 white 1 red

In that case, you are simply making less, but still have the same ratios. They are proportionate.

Happy learning!
