Answer:

Ram bought that motorcycle for Rs. 36000

Step-by-step explanation:

Given that:

Amount gained = 25%

Selling price of motorcycle = Rs. 45000

As 100% will be the original price, then 25% will be added into it.

125% will be the new percentage.

Let,

x be the original price of motorcycle.

125% of x = 45000

[tex]\frac{125}{100}x=45000[/tex]

1.25x=45000

Dividing both sides by 1.25

[tex]\frac{1.25x}{1.25}=\frac{45000}{1.25}\\[/tex]

x=36000

Hence,

Ram bought that motorcycle for Rs. 36000

Answer:

7/12

Step-by-step explanation:

Step 1: So we multiply 11 by 3, and get 33.

Then we multiply 1 by 12, and get 12.

Next we give both terms new denominators -- 12 × 3 = 36.

So now our fractions look like this:

33/36 -  12/36

Step 2: Since our denominators match, we can subtract the numerators.

33 − 12 = 2

So the answer is:

21/36

Step 3: Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Nope! So now we try the next greatest prime number, 3...

Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:

21/36 ÷ 3 =7/12

so your answer should be 7/12

The fractional expression 11/12 – 1/3 is simplified, as 7 / 12.

A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.

The expression is given below.

⇒ 11/12 – 1/3

On simplifying the expression, we have

⇒ 11/12 – 1/3

⇒ 11/12 – 4/12

⇒ (11 – 4) / 12

⇒ 7 / 12

Answer:

2.958

Step-by-step explanation:

Sample mean (x) = 38.2 MPG

Population mean (μ) = 37.9 MPG

Sample size (n) = 140

Standard deviation (σ) = 1.2

The test statistic (Tstat) can be obtained thus :

(x - μ) / σ/sqrt(n)

Tstat = (38.2 - 37.9) / 1.2/sqrt(140)

Tstat = 0.3 / 0.1014185

Tstat = 2.9580401

Test statistic = 2.958

Answer:

21,200

Step-by-step explanation:

Votes casted = 53000

Votes received = 3/5

Votes did not receive = 1- 3/5 = (5-3)/5 = 2/5

Total votes not received by winner

= 53000 *2/5

= 10,600 * 2

= 21,200

Step-by-step explanation:

39.8/4=9.95, rounds to 10

Answer:

Step-by-step explanation:

(4a - 3)/(3b + 1) = 39/(a + 1) You are not going to get a numerical answer for this. Cross multiply

(4a - 3)(a + 1) = 39(3b + 1)

4a^2 + a - 3 = 117b + 39

4a^2 + a - 42 = 117b

b = [tex]\frac{a^2 +a - 42}{117}[/tex]

Answer:

b = 3

Step-by-step explanation:

I think that the relations are the following

[tex]\frac{QP}{XY}=\frac{RS}{VZ}=\frac{PT}{XW}\\\\\frac{39}{13}=\frac{4a-3}{a+1}=\frac{5a+6b}{5b+1}\\\\3=\frac{4a+3}{a-1}=\frac{5a+6b}{5b+1}[/tex]

so we first solve for a and then for b

[tex]3=\frac{4a-3}{a+1}\\\\3(a+1)=4a-3\\\\3a+3=4a-3\\\\4a-3a=3+3\\\\a=6[/tex]

and now for b

[tex]3=\frac{5a+6b}{5b+1}\\\\3(5b+1)=5a+6b\\\\15b+3=5a+6b\\\\15b=5a+6b-3\\\\15b-6b=5a-3\\\\9b=5a-3\\\\b=\frac{5a-3}{9}\\\\b=\frac{5(6)-3}{9}\\\\b=\frac{30-3}{9}\\\\b=\frac{27}{9}\\\\b=3[/tex]

Answer:

The supplier is less accurate than they have claimed

Step-by-step explanation:

Given that:

95% confidence interval of supplier's claim :

(20.45, 21.05)

Mean = (20.45 + 21.05) /2 = 41.5 / 2 = 20.75

Error margin = (upper bound - mean) = 21.05 - 20.75 = 0.30

95% confidence interval of your sample :

(20.48, 21.02)

Mean : (20.48 + 21.02) /2 = 41.05 / 2 = 20.75

Error margin = (upper bound - mean) = 21.02 - 20.75 = 0.27

0.3 > 0.27

From the calculations made, the mean are the same, but the error margin of supplier is higher, thus it could be concluded that the supplier is less accurate than they have claimed

Step-by-step explanation:

Answer:

There is enough evidence to prove they are congruent. AAS would be what's used in this case.

Step-by-step explanation:

(< = angle)

<B = <Z, <A = <Y, line AC and line XY are equal.

Edit: So it appears that each of the photos are congruent. They have enough labels on them to tell you that their last unidentified angle would have to be congruent as well, meaning that each picture is congruent.

Answer:

x=2, y=1

Step-by-step explanation:

since they are both congruent, the corresponding sides are also congruent

Thus:

2x+1=x+3

x+y=3x-3y

First, solve 2x+1=x+3

[tex]2x+1=x+3[/tex]

Subtract both sides by x

[tex]2x-x+1=x-x+3\\[/tex]

[tex]x+1=x+3[/tex]

Subtract both sides by 1

[tex]x+1-1=x+3-1[/tex]

[tex]x=2[/tex]

Thus x=2

Next, solve for x+y=3x-3y

[tex]x+y=3x-3y[/tex]

Substitute x with 2 (from the first part)

[tex]2+y=3(2)-3y[/tex]

[tex]2+y-y=6-3y-y[/tex]

[tex]2=6-4y[/tex]

[tex]2-6=6-4y-6[/tex]

[tex]\frac{-4=-4y}{-4}[/tex]

[tex]y=1[/tex]

Thus y=1

Answer: m<5 is 71 degrees, m<8 is 109 degrees

Step-by-step explanation: M<5 and m<1 are corresponding angles, so they have the same angle measurement.

M<5 and M<8 are angles on a line, meaning they must add up to 180 degrees, so you subtract m<5's angle measure from 180 to find that m<8 is 109 degrees.

Answer:

20% of 250 is 50

Answer:

The equation is;

y = -1/4x + 607.5

Step-by-step explanation:

Let us have the number of drops as y axis while the number of minutes is x axis

The points to use are;

(30,600) and (130,575)

The slope can be calculated using;

m = (y2-y1)/(x2-x1)

= (575-600)/(130-30) = -25/100 = -1/4

So the equation as we model using the normal equation of a straight line (y = mx + c, m is slope and c is the intercept)

y = -1/4x + c

To get c, we simply substitute one point

Let us use (30,600)

We have

600 = -1/4(30) + c

600 + 7.5 = c

c = 607.5

So the equation is ;

y = -1/4x + 607.5
