Mr Rai sale a watch for Rs 2035 a profit of 10% how much money has he paid to buy the also find his profit amount
Answer:
He paid Rs 1,850 to buy the watch
Profit = Rs 185
Step-by-step explanation:
Cost price = x
Profit = 10% of x
Selling price = Rs 2035
Profit = Selling price - cost price
10% of x = 2035 - x
0.1x = 2035 - x
0.1x + x = 2035
1.1x = 2035
x = 2035 / 1.1
x = 1,850
Cost price = x = Rs 1,850
Profit = 10% of x
= 10% of 1,850
= 0.1 × 1850
= 185
Profit = Rs 185
Maria's luggage travels 36 m in 3 minutes. What is the speed of the conveyer belt in kilometers per hour?
Answer:
0.72 km per hour
Step-by-step explanation:
First, find the speed in meters per hour. Create a proportion where x is this speed:
[tex]\frac{36}{3}[/tex] = [tex]\frac{x}{60}[/tex]
3x = 2160
x = 720
So, the speed is 720 meters per hour. Convert this to kilometers per hour by dividing 720 by 1000, since there are 1000 meters in a kilometer:
720/1000
= 0.72
So, the speed of the conveyer belt is 0.72 km per hour

complete the equation: x^2-14x + __ = (__)^2
a. -14; x+14
b. -14; x-14
c. 49; x-7
d. 49; x+7
Answer:
C. 49, x-7
Step-by-step explanation:
(A+B)^2 = A^2 + 2AB + B^2
-14x = 2*A*B
where A=x
Therefore B=-7
and (x-7)^2=x^2-14x+49

Y=3/4x - 6 find the x-intercept of the line
Answer:
The x intercept is (8,0)
Step-by-step explanation:
To find the x intercept set y = 0 and solve for x
Y=3/4x - 6
0 =3/4x - 6
6 = 3/4x
4/3 *6 = 4/3*3/4x
8 =x
The x intercept is (8,0)
Answer:
8
Step-by-step explanation:
0 =3/4x - 6
6 = 3/4x
24 = 3x
x = 24/3 = 8

Identify the segments that are parallel, if any, if ∠DCB and ∠CDA are supplementary.
Answer:
C
Step-by-step explanation:
We are given that
[tex]\angle[/tex]DCB and [tex]\angle[/tex]CDA are supplementary.
We have to identify the parallel segments if [tex]\angle[/tex]DCB and [tex]\angle[/tex]CDA are supplementary.
Supplementary angles: If the angles are supplementary then the sum of two angles is 180 degrees.
Therefore,
[tex]\angle DCB+\angle CDA=180^{\circ}[/tex]
Therefore, angle DCB and angle CDA are interior angles .
Because CA is a transversal line and sum of interior angles is 180 degrees.
When the sum of interior angles formed between two lines and on same side of transversal line is 180 degrees. Then the lines are parallel.
Therefore, angle DCB and angle CDA are formed between line AD and BC.
Hence, AD is parallel to BC.
Option C is correct.

Answer:
Step-by-step explanation:
All these amount of money are based on Dan's initial amount, which is x. Ben had 7 more than Dan, so Ben's amount of money is x + 7. Kaden has 4 more than Ben, so Kaden's amount of money is 4 + (x + 7) which is x + 11. So here's the breakdown so far:
Dan: x
Ben: x + 7
Kaden: x + 11
Now it looks like Kaden is the favorite and got another 20 from his mom, so his amount became x + 31. After Dan spends a dollar, making his amount x - 1, Kaden had 9 times what Dan had. Now we have finally:
x + 31 = 9(x - 1) and
x + 31 = 9x - 9 and
40 = 8x so
x = 5.
Dan originally had $5, Ben originally had $12, and Kaden originally had $16
For the function f(x) = -4^-x + 5, if x→∞, then y → ____.

Answer:
the first choice
Step-by-step explanation:
Events A and B are independent if the equation P(A∩B) = P(A) · P(B) holds true.
then it means if the events are independent then the probability is multiplying the probability of each event.
Lyon walked 3/4 mile from school to the soccer field.
He then walked 1/6 mile home.
About how many miles did Lyon walk?
Answer:
11/12 miles Lyon walk.
Step-by-step explanation:
3/4 -> 9/12
1/6 -> 2/12
9 + 2 = 11
The solution is :about 11/12 miles Lyon walk.
What is addition?Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.
here, we have,
given that,
Lyon walked 3/4 mile from school to the soccer field.
He then walked 1/6 mile home.
now, we have to find that,
About how many miles did Lyon walk
so, we need to add the both distance
i.e. 3/4 + 1/6
so, we have,
3/4 -> 9/12
1/6 -> 2/12
so, we get,
9 + 2 = 11
i.e. 3/4 + 1/6
= 9/12 + 2/12
=11/12
Hence, about 11/12 miles Lyon walk.

You have just used the network planning model for a county road resurfacing project and found the critical path length is 40 days and the standard deviation of the critical path is 10 days. Suppose you want to pick a time (in days) within which you will complete the project with 90% confidence level. What should be that time (in days and round to the nearest whole number)
Answer:
The answer is "53 days"
Step-by-step explanation:
The form for the due date is given below from the above information.
[tex]\text{DUE DATE = Expected Completion Time} + (Z \times \text{Standard Deviation)}[/tex]
The level of confidence relates to the percentage of all samples which can contain a true population variable. It is calculated by a random sampling of the population and is often linked with a certain level of confidence, which would be a probability, usually a percent. The 90% say that the true mean will be 90%, but 10% won't.
The Z-score needs to be measured, measured from percentage points away from the mean in statistics of a value related to the mean (which is to say, the average) of one sequence of items.
[tex]Expected\ time = 40 \\\\Confidence \ interval = 90 = Z-VALUE \ of\ 1.282\\\\Standard \ Deviation= 10\\\\DUE \ DATE = 40 + (1.282 \times 10) = 53 \ days\\\\= 40+ 12.82 =52.82 \approx 53\\\\\therefore[/tex]
The time in days is 53 days.
Would this be 20? I'm confused on what the problem is asking here.
Answer:
This would not be 20
Step-by-step explanation:
This question can be thought as a Pythagoras question.
By subtracting 2cm from both the left side ZW, and the right side YX, you will have a right angled triangle WYX (or ZYX, since after subtracting 2cm Z and W are essentially the same point)
I have attached a crude drawing of what the triangle is looking like, we are looking for the unknown value marked with the ?
Pythagoras states that [tex]a^{2} +b^{2} =c^{2}[/tex]
We are given the lengths 2cm and 20cm, which can be thought of as a (or b) and c. Substitute in the values 2 and 20 and solve for the unknown

Find the measure of the indicated angle to the nearest degree.
?
Answer:
18
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp /adj
tan ? = 11/34
Taking the inverse tan of each side
tan ^-1 (tan ?) = tan ^-1 (11/34)
? =17.92791
To the nearest degrees
? = 18
Answer:
Set the measure of the indicated angle as x:
[tex]tan(x)=\frac{11}{34}\\\\x=tan^{-1}(\frac{11}{34})\\\\x=17.9279...[/tex]
Therefore, the measure of the indicated angle is around 18°

Answer:
Solution: means we replace 'x' with 'x+1' and we get g (x). Let us put x = 0 and then y = 0 to find two points on coordinate axis to easily plot the graph of g (x). Now, let us put y = 0 and find out x. So, second point is . Now, let us plot A and B then extend the line joining AB.
