Answer:
13.8
Step-by-step explanation:
16 - 2.2 is the question.
WE can split this problem up into 2.
16 - 2 and 1 - 0.2.
16 -2 = 14
1 - 0.2 = 0.8
14 - 1 = 13 ( we subtract by 1 because we added one to 16.)
13 + 0.8 = 13.8

(or the other way)
16 - 2.2
16 - 2 = 14
14 - 0.2 = 13.8

Ive been having this question for a while "what do you use first PEMDAS or Order of Operations". Well you might say it doesn't matter because a problem like this 5(3+8)=x if you use PEMDAS u first add the eight and the three and you would get eleven then you times the eleven with the five to get fifty five. So x=55. If you use Order of Operations you would multiply the three and eight by five to get 15+40=x you would add the fifteen and the forty to get fifty five making x=55. But if you took the problem {3(525/4π)}^1/3=R
then its a different situation heres the problem solved with PEMDAS.
{3(525/4π)}^1/3
{3(525/12.57)}^1/3
{3•41.77}^1/3
125.30^1/3=4.90
R=4.90
Now this is a step by step explanation on how to do order of operations.
{3(525/4π)}^1/3
(1575/12•9.40)^1/3
(1575/112.80)^1/3
13.90^1/3=2.30
R=2.30
So as you see these two equations have different answers. Now agin which of the two of them do i use Order of Operations or PEMDAS.
Please give a step by step explanation why i should use either or. All these problems were rounded to the nearest hundredth.
Answer:
Order of Operations was aught at a younger age for those just grasping the idea of multiplication and division. Exposing PEMDAS at a young age would confuse them too much, hence the order of operation groups, addition/subtraction and multiplication/division. So for the second example problem, PEMDAS would be correct because it does involve you to use parentheses as well as exponents to solve for. Very easy to mix up between order of operations and PEMDAS, but just look at it as if Order of operations is a beginner level of PEMDAS.

Find the total surface area of the pyramid with base length and height be 10 cm and 12 cm respectively.
Answer:
Hence, total surface area of the pyramid is 360 cm².
Step-by-step explanation:
We first calculate slant height L of the pyramid with base s=10 cm and height 12 cm:
L²=H²+(s/2)²=122+(10/2)²=122+5²
=144+25=169⇒
L=(169)^1/2=13
The perimeter of the base is P=4s, since it is a square, therefore,
P=4×10=40 cm
The general formula for the lateral surface area of a regular pyramid is LSA=1/2Pl where P represents the perimeter of the base and l is the slant height.
Since the perimeter of the pyramid is P=40 cm and the slant height is l=13 cm, therefore, the lateral surface area is:
LSA=1/2Pl=1/2×40×13=260 cm²
Now, the area of the base B=s² with s=10 cm is:
B=s²=10²=100 cm²
The general formula for the total surface area of a regular pyramid is TSA=1/2Pl+B where P represents the perimeter of the base, l is the slant height and B is the area of the base.
Since LSA=1/2Pl=260 cm² and area of the base is B=100 cm², therefore, the total surface area is:
TSA=1/2Pl+B=260+100=360 cm²
Hence, total surface area of the pyramid is 360 cm².
Jessica Rabbit is the manager of shipping and receiving and has been working at the Leanup Company for thirty years. She rarely calls in sick and gets good performance reviews every year. In the past year, her wife’s company has been in serious financial trouble; they likely will not be able to make the payroll for next month and may have to close down.

A recipe calls for 4 cups of pecans for every 5 cups of walnuts. How many cups of pecans should be added to 8 cups of walnuts?
Answer:
5 walnuts = 4 cups of pecans
8 walnuts = 9 cups of pecans
Answer:
10 cups of pecans.
Step-by-step explanation:
The ratio between pecans and walnuts are: [tex]\frac{4}{5}[/tex]×8
So if we make a smaller batch with 1 cup of walnuts, we will need [tex]\frac{4}{5}[/tex] cup of pecans.
So for 8 cups of walnuts, we will need [tex]\frac{4}{5}[/tex] x 8 = 6,4 cups or [tex]6 \frac{2}{5}[/tex] cups of pecans.

Mary takes 8 days to do a full check of the

4 days.
Answer:
Step-by-step explanation:
[tex]\begin{array}{|c|c|c|c|c}day&1&2&3&4\\----&-----&-----&-----&-----\\Mary&\frac{1}{8} &\frac{2}{8} &\frac{3}{8} &\frac{4}{8} \\Assis&\frac{1}{12} &\frac{2}{12} &\frac{3}{12} &\frac{4}{12} \\Sum&\frac{1}{8}+\frac{1}{12}&\frac{2}{8}+\frac{2}{12}&\frac{3}{8}+\frac{3}{12}&\frac{4}{8}+\frac{4}{12}\\part&\frac{5}{24}&\frac{10}{24}&\frac{15}{24}&\frac{20}{24}=\boxed{\frac{5}{6}}\\----&-----&-----&-----&-----\\\end{array}[/tex]
The fraction of the catalog that is checked after 4 days is 5/6
If Mary takes 8 days to do a full check and her assistant takes 12 days then if they work together then the fraction of the catalog that is checked after 4 days is 1000/12.
What is fraction?Fraction is a combination of numerator and denominator. The number above division sign is known as numerator and the number below the division sign is known as denominator. It is in p/q form in which q cannot be equal to 0.
How to find fraction?let the catalog contains 100 things.So in this way ,
In 1 day Mary does 100/8 things completed and her assistant does 100/12 things completed in 1 day.
So in four days they will complete =100*4/8+100*4/12
=400/8+400/12
=(4800+3200)/96
=8000/96
=1000/12
Hence if Mary takes 8 days to do a full check and her assistant takes 12 days then if they work together then the fraction of the catalog that is checked after 4 days is 1000/12.

Solve quadratic equation by factoring.
Answer:
x = -5 and x = -9.
Step-by-step explanation:
To factor this, we need to find two numbers that add to 14 and multiply to 45. These are 5 and 9. Therefore, this equation factors to (x + 5)(x + 9) = 0. The two x values that would make this true are -5 and -9 because they would make (x + 5) and (x + 9) equal to 0 respectively.
Identify the equation of the circle that has its center at (9, 12) and passes through the origin.
Answer: [tex](x-9)^2 + (y-12)^2 = 225\\\\[/tex]
This is the same as writing (x-9)^2 + (x-12)^2 = 225
========================================================
Explanation:
Any circle equation fits the template of [tex](x-h)^2 + (y-k)^2 = r^2\\\\[/tex]
The center is (9,12) which tells us the values of h and k in that exact order.
h = 9
k = 12
To find the radius r, we need to find the distance from the center (9,12) to a point on the circle. The only point we know on the circle is the origin (0,0).
Apply the distance formula to find the distance from (9,12) to (0,0)
[tex]d = \sqrt{ (x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{ (9-0)^2+(12-0)^2}\\\\d = \sqrt{ (9)^2+(12)^2}\\\\d = \sqrt{ 81+144}\\\\d = \sqrt{ 225}\\\\d = 15\\\\[/tex]
The distance from (9,12) to (0,0) is 15 units. Therefore, r = 15
An alternative to finding this r value is to apply the pythagorean theorem. The distance formula is effectively a modified version of the pythagorean theorem.
---------------------
Since h = 9, k = 12 and r = 15, we can then say:
[tex](x-h)^2 + (y-k)^2 = r^2\\\\(x-9)^2 + (y-12)^2 = 15^2\\\\(x-9)^2 + (y-12)^2 = 225\\\\[/tex]
which is the equation of this circle.
