In a particular country, the coins come in the denominations 1, 15 and 50 schillings. Whilst visiting this country, Peter bought a book for his wife, Rachel, paying with several (more than 2) coins. He paid with the minimum number of coins needed to make that amount.

His change contained one more coin than the handful of coins with which he paid, but again it was the minimum number of coins needed to make that amount.

What are the eight lowest possible prices for the book?

What is the lowest price of the book where the coins Peter pays with is a sensible set of coins to have handed over?

Answers

Answer:

Step-by-step explanation:

Depending on the tools available to your 11y.o., it's a typical question for linear inequalities.

Where a,b,c are the # of 1,15,50 coins given by the buyer, and d,e,f the # of coins given back by the seller.

1×a + 15×b + 50×c > 1×d + 15×e + 50×f

a+b+c+1>=d+e+f

a+b+c >=2

Now, there are other clues in the text :

If the seller gives back money, then you didn't pay with 1's, otherwise, it means you overpay and you could have given fewer coins. So a=0.

Similarly, the seller cannot give you back a coin of 50, otherwise, you could have given fewer coins as the buyer. So f=0.

So that gives :

15×b + 50×c > 1×d + 15×e

b+c+1>=d+e

b+c >=2

From that point on, there is only a handful of scenarios to test.

Solve using a matrix

Answers

Solution of the system of equation 3x + y = 5 , 5x + 2y = 9 using matrix is x =1 and y =2.

As given in the question,

System of equation:

3x + y = 5 ,

5x + 2y = 9

In matrix form :

[tex]\left[\begin{array}{ccc}3&1\\5&2\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}5\\9\end{array}\right][/tex]

[tex]D = \left[\begin{array}{ccc}3&1\\5&2\end{array}\right][/tex]

   = (3)(2) -(5)(1)

   =1

[tex]D_{x} = \left[\begin{array}{ccc}5&1\\9&2\end{array}\right][/tex]

     = 10 -9

     = 1

[tex]D_{y} = \left[\begin{array}{ccc}3&5\\5&9\end{array}\right][/tex]

    = 27 -25

    = 2

[tex]x= \frac{D_{x}}{D}[/tex]

  = 1

[tex]y =\frac{D_{y}}{D}[/tex]

  =2

Therefore, solution of the system of equation 3x + y = 5 , 5x + 2y = 9 using matrix is x =1 and y =2.

#SPJ1

what is the height of this cone?

Answers

Answer:

height is = 3/2 ft

Step-by-step explanation:

a cones volume can be represented by 1/3(h)(pi)(r^2)

we must go backwards to find this question out

if the diameter is 2/3 then the radius is 1/3

then you must square that

that is 1/3 * 1/3 which is 1/9

1/9(1/3)(pi)(h) is 1/18(pi)

we can remove pi from both sides and multiply the 1/9 and the 1/3

1/27(h) = 1/18

we must find the lcm or least common multiple to figure this out

the lcm is 54

1/27 is essentially 2/54 and 1/18 is 3/54

2/54(h) = 3/54

we can multiply each side by 54

2h = 3

divide 2 on both sides

h is 3/2

A triangle has an area of 156 square millimeters and a base of 16 millimeters. What is the
height?

Answers

Answer: Height = 19.5mm

Step-by-step explanation:

The area of a triangle is the base*height/2.

We can plug in the values given for the base and area.

Therefore, 156 mm^2 = 16mm*height/2

Multiply both sides by 2:

312 mm^2 = 16mm*height

Divide both sides by 16mm:

Height = 19.5mm

Write the percent as a fraction and decimal:
72%, 25%, 500%, 5%

Answers

Answer:

Decimals:

0.72, 0.25, 5.0, 0.05

Fractions in simplest forms:

18/25, 1/4, 5/1, 1/20

Step-by-step explanation:

To convert percentages into decimals:

You divide the percentage by 100.

To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.

To convert a percent to a fraction, we have to remove the percent sign and divide the given number by 100. And, then we express the fractional form of the percentage in the simplest form. For example, 1% is 1/100, 2% is 2/100 which can be reduced to 1/50.

Jaden says that two triangles are congruent if their interior angles are congruent. Is Jaden correct, and why?
Yes. Congruent triangles have congruent interior angles.
Yes. If the angles of two triangles are congruent, then the triangles are similar.
No. Congruent triangles should also have corresponding congruent side lengths.

Answers

Answer:

No

Step-by-step explanation:

No. Congruent triangles should also have corresponding congruent side lengths.

Jaden is incorrect. two triangles are not congruent if their interior angles are congruent.

The correct option is C.

What are congruent triangles?

Two triangles are said to be congruent if the three sides and the three angles of both the triangles are equal in any orientation.

Given, statement

two triangles are congruent if their interior angles are congruent.

Even when two triangles have all angles same,

they can still have sides of different lengths.

However, the ratio of lengths of corresponding sides will be same.

But in this case, they will be called 'similar' triangles, not congruent.

For example, in the image below, both triangles are equilateral and have all angles equal but they are not congruent.

Hence,  two triangles with congruent angles are not congruent, Jaden is incorrect.
