The scale on a map is 1 :50000.
The area of a field on the map
is 1.2square centimetres.
Calculate the actual area of the field in square kilometres.
Answer:
The actual area of the field in square kilometers is [tex]30000000 km^2[/tex]
Step-by-step explanation:
Scale : 1 cm = 50000 km
Area of field on map = [tex]1.2 cm^2[/tex]
Now , 1 cm = 5000 km
[tex]1 cm^2 = (5000 km)^2[/tex]
We are supposed to find the actual area of the field in square kilometers.
So, the actual area of the field in sq. km =[tex]1.2 \times (5000)^2[/tex]
Actual area of the field in sq. km [tex]=30000000 km^2[/tex]
Hence the actual area of the field in square kilometers is [tex]30000000 km^2[/tex]
Is 40 cm equal to 4 m?
Answer:
There are 100 centimetres in one metre. Therefore, 4 metres is equal to 4 x 100 = 400 centimetres. This is longer than 40 centimetres.
7. Sociologists can get three possible answers to a typical survey question such as "Do you believe in the tooth fairy?" - namely, yes, no and no opinion. With this in mind, the Sociomagnetic Computer Company has decided to build a computer to process survey data. This computer has a trinary memory - that is, each byte (tryte?)consists of 8 trits, with a trit holding a 0, 1, or 2. How many trits are needed to hold a 6-bit number? Give an expression for the number of trits needed to hold n bits.
Answer:
1. n ≥ 4
2. N ≥ nlog(2)÷log3
Step-by-step explanation:
1
1 byte = 8 bits
each byte = 8 trits
a 6 bit number = [tex]2^{6} = 64[/tex]
3n ≥ 64
divide through by3
n ≥ 64/3
we take the logarithm
n ≥ [tex]\frac{log64}{log3}[/tex]
n ≥ 1.8062 ÷ 0.4771
n≥3.785
when approximated, n ≥ 4. So the number of trits needed in the storage of 6 bit is atleast 4
2.
to hold n bits, we can do something similar.
3N ≥ 2n
we take log of both sides
such that;
N ≥ [tex]\frac{nlog(2)}{log(3)}[/tex]
Each costume needs 46 centimeters of red ribbon and 3 times as much yellow ribbon. What is the total length of the ribbon needed for 64 costumes? Express your answer in meters.
Answer:
I think its 117.76 meters
Step-by-step explanation:
you multiply the 46 x 3 then you get 138 yellow ribbon then 138 + 46 then its 184 then 184 x 6 = 11776
Answer:
117.76 meters
Step-by-step explanation:
46x64=2,944 (red ribbon)
46x3=138x64=8,832 (yellow ribbon)
8,832+2,944=11,776 (all ribbon)
11,776 centimeters converted into meters is 117.76 meters

Suppose the manager of your local McDonalds tracks the
monthly sales of their new McBurger, Mini McBurger, and
Choco-Latte Shake. The data is listed below.
For January through December, the sales are as follows.
McBurger: 46, 63, 58, 77, 81, 102, 183, 197, 125, 111, 83, 218.
Mini McBurger: 23, 41, 35, 44, 62, 88, 95, 99, 108, 111, 98, 63.
Choco-Latte Shake: 88, 46, 39, 52, 67, 99, 189, 238, 188, 97,
51, 12
Create a matrix to display the data.
Answer:
Step-by-step explanation:
The question says "Create a matrix to display the data".
The are 3 products:
- McBurger - Mini McBurger - ChocoLatte Shake
The figures represent monthly sales for each product, in a given year. This means 12 figures for each product - represent the 12 months of the year.
These figures will appear on the matrix, with the horizontal arrangement representing each month of the year and the vertical arrangement representing each product's sales.
In that light, you'll have a 12 by 3 matrix.

The first column represents sale of McBurger, the second column represents sale of Mini McBurger, the third column represents sale of Choco-Latte Shake.
You own 16 CDs. You want to randomly arrange 5 of them in a CD rack. What is the probability that the rack ends up in alphabetical order?
Answer:
[tex]\frac{1}{524160} or 1.910^{-6}[/tex]
Step-by-step explanation:
In order to solve this, you would need to multiply the probability of you choosing the one that goes first, so 1 in 16 discs, then the next one so 1 in 15, and so on untill the fifth disc.
So you would have to do this:
[tex](\frac{1}{16})(\frac{1}{15})(\frac{1}{14})(\frac{1}{13})(\frac{1}{12})\\\frac{1}{524160}[/tex]
That is the probability that the rack ends up in alphabetical order, if you pull discs randomly, 1 in 524160 chances.
Probabilities are used to determine the chances of an event.
The probability that the rack ends up in alphabetical order is [tex]\mathbf{ \frac{1}{524160}}[/tex]
The given parameters are:
[tex]\mathbf{CD = 16}[/tex]
[tex]\mathbf{r = 5}[/tex] -- CDs to arrange
So, the total number of arrangements of 5 CDs from the 16, is:
[tex]\mathbf{Total = ^{16}P_5}[/tex]
Apply permutation formula
[tex]\mathbf{Total = \frac{16!}{(16 - 5)!}}[/tex]
This gives
[tex]\mathbf{Total = \frac{16!}{11!}}[/tex]
Expand
[tex]\mathbf{Total = \frac{16 \times 15 \times 14 \times 13 \times 12 \times 11!}{11!}}[/tex]
[tex]\mathbf{Total = 16 \times 15 \times 14 \times 13 \times 12 }[/tex]
[tex]\mathbf{Total = 524160}[/tex]
There is only one possibility of the CDs being in alphabetical order.
So, the probability is:
[tex]\mathbf{Pr = \frac{1}{524160}}[/tex]
Hence, the probability that the rack ends up in alphabetical order is [tex]\mathbf{ \frac{1}{524160}}[/tex]

The percentage increase for flight tickets to fly from orlando to hartford would be = 67.5% and 92.5% when there is an additional $50 to the new price.
What is percentage Increase?Percentage increase is defined as the rise in the quantity or amount for an object which is converted into percentage.
The formula for percentage increase would be = increase ÷ original amount × 100
The increase of the cost = 335 - 200 = $135
The original amount = $200
The percentage increase = 135/200 × 100
= 13500/200 = 67.5%
But if the increase in cost is 135 + 50 = $185
The percentage increase of the new cost would be;

(st

22 - 50 - 10
I2 – 50 + 10
2 – 100 - 25
22 - 10x + 25
Answer:
D.) x²-10x+25 sq. units
Step-by-step explanation:
The question is not properly written. The question should have been:
If each side of a square is (x-5) units, which expression can be used to represent the area of the square.
Area of a square = L² where:
L is the length of the square
Given
L = x-5
Required
Area of the square
Substitute the given function into the formula to get the required as shown:
Area of the square = (x-5)²
Expand
A(x) = (x-5)(x-5)
A(x) = x(x)-5x-5x-5(-5)
A(x) = x²-10x-25
Hence the area of the square is (x²-10x+25)sq. units. Option D is correct.

Pieces of Mail. The number of pieces of mail
handled by the U.S. Postal Service decreased from
212 billion in 2007 to 168 billion in 2011. What is the
percent decrease?
Answer:
20.8%
Step-by-step explanation:
The number of the pieces of mail handled by the U.S postal service decreased from 212,000,000,000 to 168,000,000
Therefore the percentage decrease can be calculated as follows
= 212,000,000,000-168,000,000,000
= 44,000,000,000/212,000,000,000 × 100
= 0.2075 × 100
= 20.8 %
Hence the percentage decrease is 20.8%
