There is a difference of actual and approximations 9.46 dollars.

Unitary method is a mathematical way of first deriving the value of a single unit then multiplying the given unit to obtain the required result.

According to the given question we have to compare the results where in first case we put actual values and on the second case we round the values.

In the first case

You're going on a 1211 mile trip, and your car gets about 29 miles per gallon.

So, the total fuel consumption will be (1211/29) gallons which is

= 41.76 gallons.

Given 1 gallon of gas costs 3.10 dollars.

∴ 41.76 gallons of gas will cost ( 41.76×3.10) dollars which is

= 129.456 dollars.

= 129.46 dollars.

In the second case

It is a 1200 mile trip and the fuel economy of the car is 30 miles per gallon.

So, the total fuel consumption will be

= 1200/30

= 40 gallons.

Given 1 gallon of gas costs 3 dollars.

∴ 40 gallons of gas costs (40×3) dollars which is

= 120 dollars.

The four sides of the quadrilateral are 9 m,10 m, 11 m and 12 m.

What is a quadrilateral?

A quadrilateral is a four-sided polygon with four angles and four vertices. The term "quadrilateral" comes from the Latin words "quadri," which means "four," and "latus," which means "side."

Let the four sides of the quadrilateral be (x-2), (x-1), x, (x+1).

Then, perimeter = (x-2) + (x-1) + x + (x+1)

i.e., x - 2 + x - 1 + x + x + 1 = 42

i.e., 4x - 2 = 42

i.e., 4x = 42 + 2

i.e., 4x = 44

i.e., x = 11

Hence, the four sides of the quadrilateral are 9 meters, 10 meters, 11 meters and 12 meters.

The lengths of the candlesticks for September 8 and 11 are approximately the same because this physical object stands in for the price range between the opening and closing prices for that trading day.

The close was lower than the open if the true body is filled in or is completely black. Real bodies that are empty indicate that the close was higher than the open.

Let's consider a case study over a longer time frame, say a week. In this example, the candle records prices from Monday through Friday of the work week. The price at which the market starts on Monday at 9:15 a.m., the first business day of the week, will be the opening price. The highest and lowest prices ever recorded will be set during that particular week.

Over a century before the West created the bar and point-and-figure charts, candlestick charts were invented in Japan. While there was a correlation between rice price and supply and demand in the 1700s, a Japanese man by the name of Homma found that traders' emotions had a significant impact on the markets.

Accordingly the Venn diagram The required values of x = 12 , y = 13 , z = 24 and t = 13.

A Venn diagram uses overlapping circles or other shapes to illustrate the logical relationships between two or more sets of items.

In Venn diagram, if two sets A and B do not intersect, then n(A∩B)=0 and n(A∪B) = n(A) + n(B).

Given: n(U) = 50, n(A) = 25, n(B) = 13 and n(A'∩B')=12

We have to determine the values of x, y, z, and t.

According to the given figure,

n(A') = n(U) - n(A)

n(A')=  50 - 25

n(A') = 25

n(B') = n(U) - n(B)

n(B') = 50 - 13

n(B') = 37

n(A∩B) = n(A') - n(A'∩B')

n(A∩B) = 25 - 12

n(A∩B) = 13

So, y = n(A∩B) = 13

As  in the Venn diagram, we know that,

x + y = n(A')

x = n(A') - y

x = 25 - 13

x = 12

y + z = n(B')

13 + z = 37

z = 37 - 13

z = 24

t = n(U) - [n(A) + n(B)]

t = 50 - [25+13]

t = 50 - 37

t = 13

Therefore, the values of x, y, z and t are 12, 13, 24, and 13.

Answer:

Step-by-step explanation:

SP is part of a line and line is 180°

so:

m∠PQR + m∠RQS= 180°

(3x-5)  + ( x+1) = 4x-4=180

4x = 184

x= 46

m∠PQR = 3X-5 = 3(46)-5 =133

Answer:

133

Step-by-step explanation:

Supplementary angles are angles that sum to 180°, meaning they form a straight line.

Solving for x

Since we know that these 2 angles will sum to 180 (remember they are supplementary) we can add their expression together and set it equal to 180.

Next, combine like terms.

Add 4 to both sides

Divide by 4

Solve for m∠PQR

Now that we know the value of x, we can find the measure of PQR. Simply plug 46 in for x and solve.

This means that m∠PQR = 133°.

Answer:

-3

Step-by-step explanation:

1) -x-y = 9

2) -3x+y = 3

By adding 3x to each side on equation #2, you get that y = 3+3x.

Now, we can substitute the value of y into the second equation. If you do this, you will get that [tex]-x-(3+3x)=9[/tex].

Simplifying gives you: [tex]-4x-3=9[/tex]

Adding three to both sides: [tex]-4x=12[/tex]

And finally dividing by negative four: [tex]x=-3[/tex]

You will get x = -3

The value of x for a given logarithm is 49.9.

Log10(x²+4)=2+Log10x-Log10 20​=

x = 49.9

2 = log10( 100)

so we have

log10( x [tex]\times[/tex]2 4) = log10( 100) log10( x)- log10( 20).

factor out log10 from RHS.

also log10( [tex]x[/tex] x  2 4) = log10( 100x/ 20).

log10 cancel log10.so, break the quadratic equation after simplification to have x = 49.9 or0.080

That is, the logarithm of a given integer x is the exponent to which another set number, the base b, must be increased in order to produce x. In the most the logarithm counts the number of times the same factor appears in repeated addition; for illustration, since 1000 = 10 10 10 = 103, the" logarithm base 10" of 1000 is 3, or log10( 1000) = 3. When no mistake is conceivable, or when the base does not important, the logarithm of x to base b is expressed as logb( x), without logb x, or indeed without the base, logx.
