What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

The diameter of a circle is 15 m. Find the circumference \textit{to the nearest tenth}to the nearest tenth.

Answers

Given that, the diameter of the circle 15 m. The circumference of a circle is 2πr. Then the circumference of the circle with the given diameter is 47.1  m.

What is circumference of a circle?

Circumference of a circle is also called its perimeter and it describes the overall area of the surrounding circular path. The distance round a circle is its circumference, but this cannot be used as a definition if, as in many elementary treatments, distance is defined in terms of straight lines.

In these conditions, the limit of the perimeters of inscribed regular polygons may be described as the circumference of a circle as the number of sides increases without constraint.  When describing abstract geometric forms as well as measuring real-world things, the term circumference is frequently used.

It is given that, the diameter of the circle = 15 m

radius r  = diameter/ 2 = 15 m/ 2 = 7.5 m

circumference of circle = 2 π r

                                       = 2 × 3.14 × 7.5 m

                                       = 47.1 m

Jerome bought 2 postcards and received $1.50 in change in quarters,dimes. And nickels.The nickels, were worth $0.15.If he got 9 coins, back how many of each coin did he get

Answers

Answer:

Jerome got 5 quarters, 1 dime and, and 3 nickels.

Step-by-step explanation:

Let's define the variables:

N = number of nickels he got

D = number of dimes he got

Q = number of quarters he got

We know that the nickels were worth $0.15

And each nickel is whort $0.05

Then:

N*$0.05 = $0.15

N = $0.15/$0.05 = 3

N = 3

Now we also know that there is a total of 9 coins, then:

N + D + Q = 9

3 + D + Q = 9

D + Q = 9 - 3 = 6

D + Q = 6

And we also know that the total change received is $1.50, then:

D*$0.10 + Q*$0.25 + N*$0.05 = $1.50

We know that N = 3, then we can replace that and get:

D*$0.10 + Q*$0.25 + 3*$0.05 = $1.50

D*$0.10 + Q*$0.25 = $1.50 - $0.15 = $1.35

D*$0.10 + Q*$0.25 = $1.35

Then we have two equations:

D + Q = 6

D*$0.10 + Q*$0.25 = $1.35

To solve this, we can isolate one of the variables in one of the equations, i will isolate D in the first one:

D = 6 - Q

Now we can replace this in the other equation:

(6 - Q)*$0.10 + Q*$0.25 = $1.35

Now we need to solve this for Q.

$0.60 - Q*$0.10 + Q*$0.25 = $1.35

Q*$0.15 = $1.35 - $0.60 = $0.75

Q = ($0.75)/($0.15) = 5

Q = 5

Then Jerome has 5 quarters.

Now we can return to the equation:

N + Q + D = 9

We already know that:

N = 3

Q = 5

Then if we replace those in the equation, we get:

3 + 5 + D = 9

8 + D = 9

D = 9 - 8 = 1

D = 1

When melissa is born her parents invested 2,000 in a fund that paid an annual interest of 6%. How old will melissa be when the investment is worth at least $5,000?

Answers

Answer:

25 years

Step-by-step explanation:

Given data

Principal P=  $2000

Interest rate r=  6%

FInal amount A=$5,000

The simple interest formula is given as

A=P(1+rt)

substitute and solve for t

5000=2000(1+0.06*t)

5000=2000+120t

5000-2000=120t

3000=120t

t= 3000/120

t= 25 years

Hence, for a simple interest investment, she will be 25 years

Algebra - Question related to graphs?

A plane that carries mail makes a round trip each day from Chicago to New York. It makes 3 intermediate stops on the way to New York and 1 intermediate stop on the way back to Chicago. Suppose you make a graph of the altitude of the plane for one day, with time on the horizontal axis and altitude on the vertical axis. How many times will the graph touch the horizontal axis?

Well, the only time the graph would touch the x-axis (horizontal axis) would be at 0 altitude so, counting the 3 stops on the way to NY then the 1 stop back to Chicago would be four. But if you think about it when the planes are at it's destination it's also at 0 altitude. So you'd add another 3 (Chicago to New York then back to Chicago)...right? Then the graph would touch x-axis approximently 7 times?  

Dose that make sense?

1:    Yes

Way out.

The Ch is the same therefore total is 7.

How many times will the graph touch the horizontal axis?        

i guess it would be 7 as the answer because: Well, the only time the graph would touch the x-axis (horizontal axis) would be at 0 altitude so, counting the 3 stops on the way to NY then the 1 stop back to Chicago would be four. But if you think about it when the planes are at it's destination it's also at 0 altitude. So you'd add another 3 (Chicago to New York then back to Chicago)...right?

Step-by-step explanation: Different Brainly's

1:    Answer:     7

Step-by-step explanation:     The graph that is drawn here shows the altitude as a function of time. When the plane takes off from Chicago, the graph will start from the horizontal axis.

Next, when the plane takes 3 intermediate stops, altitude will touch the horizontal axis 3 times.

Next, when the plane lands in New York the altitude will touch the horizontal axis.

Next, when plane takes off from New York and takes an intermediate stop, altitude will touch horizontal axis.

Lastly the altitude will touch the axis when plane lands back in Chicago.  

So, cumulatively the altitude will touch the horizontal axis seven times.

2:    I Don't Know

3:    Answer:

5 is the right answer

Step-by-step explanation:

The graph will touch the horizontal x each time the altitude is zero.

The ordered pair works for the first equation on the top, but not the second equation on the bottom.

Step-by-step explanation:

You have to plug in the x and y values into the equations:

x - 2y = -6

2 - 2(4) = -6  

That equation works.

...now for the next one...

3x + 2y = 12

3(2) + 2(4) = 12

That equation doesn't work.

Hope this helps!

It is not because when you plug x=2 and y=4 into the second equation, it is not a true statement. In order for the ordered pair to apply to the system, there needs to be a true statement for BOTH equations not just the first one.

Observe:

2-2(4)=-6
-6=-6 this is a true statement

3(2)-2(4)=12
6-8=12
-2≠12 this is a false statement

Therefore the solution 2,4 doesn’t apply to the system since it only applies to one of the equations
