Answer:
188.24 (rounded)--- 188.2
Step-by-step explanation:
You want to first find the area of all the the different shapes you have...
you have 2 semicircles A= πr²/2 (because it is /2 you don't really need that because in the end you are going to *2 so just make the equation A= πr²)
you have a rectangle A= b*h
you have a triangle A = b*h/2
Semicircles: A= πr² = (3.14) 4² = (3.14*16) = 50.24
rectangle: A = b*h = 12*8 = 96
Triangle: A = b*h/2 = 12 * 7/2 = 84/2 = 42
then you add them up
50.24 + 96 + 42
= 188.24

a business owner pays $500 a week for rent.He also pays an employee $16 an hour.If his total weekly expenses are $1,172 ,how many hours did his employee work?
Answers
EXPLANATION:
To find the answer, we should start with the total and get rid of the amounts that we know.
So we know the total is 1,172 in a week, and that 500 dollars of it is for rent.
1,172 - 500 =672.
Now we have 672 left.
We know that it was all spent on employees.
we know it is $16 for each hour.
672 divided by 16 is 42 total hours.

Which is an example of a quadratic function whose graph opens downward and has its vertex at (0, 1)?
A. y = −x^2 + 1
B. y = x^2 + x − 1
C. y = x^2 + 4x + 1
D. y = x^2 − 1
Answers
Given:
The graph of a quadratic function opens downward and has its vertex at (0, 1).
To find:
The quadratic function.
Solution:
The vertex form of a quadratic function is:
[tex]y=a(x-h)^2+k[/tex] ...(i)
Where, a is a constant and (h,k) is the vertex.
If a<0, then graph opens downward and if a>0, then graph opens upward.
It is given that the quadratic function opens downward and has its vertex at (0, 1). It means a must be negative.
Putting h=0 and k=1 in (i), we get
[tex]y=a(x-0)^2+1[/tex]
[tex]y=ax^2+1[/tex]
For [tex]a=-1[/tex],
[tex]y=(-1)x^2+1[/tex]
[tex]y=x^2+1[/tex]
So, option A is correct.
In other options the leading coefficient is positive it means their graphs open upward. So, options B, C and D are incorrect.
Therefore, the correct option is A.

Nancy changes $759.80 and €342 into pounds sterling.
The Post Office deducts their commission and gives Nancy £827.20
What is the percentage commission?
Answers
Answer:
6% commission
Step-by-step explanation:
Exchange Rates
£1:$1.31
£1 : €1.14
$759.80 to pounds sterling :
£1 = $1.31
x = $759.80
Cross multiply :
x = 759.80 / 1.31
x = £580
£1 = €1.14
x = €342
Cross multiply :
x = 342 /1.14
x = £300
Total = £(580 + 300) = £880
Amount deducted = commision = £880 - £827.20 = £52.80
Percentage commission :
(52.80 / 880) * 100%
0.06 * 100%
= 6% commission

−4.5◯−4.49
Group of answer choices
Answers
Answer:
<
Step-by-step explanation:
-4.49 is greater than -4.5 because it is closer to a positive number.
=====================================================
Explanation:
Think of -4.5 as -4.50, then you would be able to see that -4.50 is further left compared to -4.49 and this makes -4.50 to be smaller than -4.49; therefore, -4.50 < -4.49
Keep in mind that these values are negative, so the more leftward you go, the larger the magnitude of the values will get. For example, -10 is even more to the left so it makes -10 even smaller compared to the other values mentioned. We would be able to say -10 < -4.5 and also -10 < -4.49
Side note: if the values were positive, then 4.50 > 4.49 because 50 > 49. The inequality sign flips when we change everything from positive to negative.

how do you write 3,901.25 as a scientific notation?
Answers
Answer: 3.90125×10⁻³
Step-by-step explanation:
The scientific notation consists of two parts
the number based: a, where 0<a<10the exponent based: 10ˣ, which is determined by how we change the number based "a"So the final version should be: a×10ˣ
-------------------------------------------------------------------
STEP ONE. Number based
We are given 3,901.25
In order to make it within the range of a, we should move the decimal to the left three places, or divide the number by 10³, which is times 10⁻³
We get 3.90125
STEP TWO: Exponent based
Since we changed the number by 10⁻³, this will be our exponent-based.
Therefore, it is 3.90125×10⁻³
