Step-by-step explanation:

draw 3 groups of 9 somethings or 9 groups of 3 somethings

In the 3x9 array representation there are 3 rows and 9 columns, each initialized with the value 0

Since we know that,

A set of components of the same data type are stored collectively in contiguous memory regions in an array, which is a form of data structure. To organise data sets in a way that is simple to sort and search, computer programmers employ arrays in their programmes. They can make a programme operate more quickly and are more effective at storing data than individual variables.

Sure, here's a simple array that represents a 3x9 grid:

[tex]\left[\begin{array}{ccccccccc}0&0&0&0&0&0&0&0&0\\0&0&0&0&0&0&0&0&0\\0&0&0&0&0&0&0&0&0\end{array}\right][/tex]

Answer:

6.6 stone

Step-by-step explanation:

We will use conversions to change kilograms to stones

1 kilogram= 2.2 pounds,

1 stone= 14 pounds

42 kilogram          2.2 lbs           1 stone

---------------       * -------------   * ---------------

                           1 kg                 14 lbs

All the units cancel except stone

(42*2.2)/14  stone

6.6 stone

Answer:

42 kilograms is equal to 6.6 stones.

Step-by-step explanation:

Using the given conversion factors:

1 kilogram = 2.2 pounds

1 stone = 14 pounds

To Find: 42 kilograms into stones  =  ? stones

Solution:

42 kilograms = [tex]42\times 2.2 pounds=92.4 pounds[/tex]

Another conversion factor used:

1 stone = 14 pounds

[tex]1 pound = \frac{1}{14} stones[/tex]

[tex]92.4 pounds=92.4\times \frac{1}{14} stones=6.6 stones[/tex]

So, 42 kilograms is equal to 6.6 stones.

Answer:

[tex]\frac{21}{25}[/tex]

Step-by-step explanation:

If 84% are fiction, then the fraction of these are simply the percentage over 100:

[tex]\frac{84}{100}[/tex]

Simplified down by dividing by 4:

[tex]\frac{21}{25}[/tex]

Final answer:

To convert 84% to a fraction, divide 84 and 100 by their greatest common divisor, which is 4, resulting in the simplified fraction 21/25 representing the part of Astrid's books that are fiction.

Explanation:

To convert the percentage of Astrid's books that are fiction into a fraction, we simply write the percentage as a ratio out of 100 and then simplify it. Since 84% of her books are fiction, we start with the fraction 84/100. This fraction can be simplified by dividing both the numerator and the denominator by the greatest common divisor, which is 4 in this case.

84 ÷4 = 21
100 ÷ 4 = 25

Therefore, the simplified fraction of Astrid's books that are fiction is 21/25.

Answer:

exact form=-65/4

decimal form=-16.25

Step-by-step explanation: solve for y by simplifying both sides of the equation, then isolating the variable

The solution of expression is,

⇒ y = - 16.25

We have to give that,

An expression to simplify is,

⇒ 26 = - 8/5y

Now, We can simplify the expression as,

⇒ 26 = - 8/5y

Multiply by 5 on both sides,

⇒ 26 × 5 = - 8y

⇒ 130 = - 8y

⇒ - 8y = 130

Divide both sides by - 8,

⇒ y = - 130/8

⇒ y = - 16.25

Hence, the Solution is, y = - 16.25

Answer: (-2-2i)(-4+6i) = 20 - 4i

Step-by-step explanation:

We have the expression:

(-2 - 2i)*(-4 + 6i)

the rule we need to know here is that i*i = -1

now, the first step is distribute the parentheses.

(-2 - 2i)*(-4 + 6i) = -2*-4 -2*6i - 2i*-4 - 2i*6i = 8 -12i + 8i -12*(i*i)

= 8 + (8 - 12)i +12 = 20 - 4i

300J=PM

300J/300=PM/300

J=PM/300

Answer:

J=MP/300

Step-by-step explanation:

M=300J/P

now take p to the left hand side of the equation

MP= 300J

J= PM/300

Total money Marcus has = $28

Money spent to buy a notebook = $3.75

Money left now = [tex]28-3.75=24.25[/tex]

Money needed to be saved = $11.25

So, the amount of money Marcus can spend = [tex]24.25-11.25=13[/tex]

Cost of a packet of chips = $1.30

The inequality to determine the maximum number of chips he can buy is:

Let the number of chips Marcus can buy = x

As he cannot spend more than $13 to buy chips so equation becomes:

[tex]1.30x\leq 13[/tex]

Solving this we get

[tex]x\leq 10[/tex]

Hence, Marcus can buy a maximum of 10 packs of chips and  save $11.25

It is given that,

there are 8 balls in the bag numbered 1 to 8

Only one ball color is gray and all others are white

P(X) = probability of getting white ball

P(not X) = Probability of getting gray ball

a)  To find Probabilities P(X) and P(not X)

For event X, 1,3,4,5,6,7,8 are checked and P(X) = 7/8

for event 'not X' only 2 is checked and P(not X ) = 1/8

b) To find 1 - P(X)

1 - P(X) = 1 - 7/8 = (8 - 7)/8 = 1/8  

c)1 - P(X) is same as P(not X)

If C is the cost and x the amount of cans.

Answer:

4 - π

Step-by-step explanation:

(a) Radius of circle

  A = πr²      Substitute value of A

4π = πr²      Divide each side by π

 r² = 4         Take the square root of each side

  r = 2

(b) Area of MON

A = ¼ × area of circle

A = ¼ × 4π

A = π

(c) Area of MONP

 l = r      Substitute the value of r

 l = 2

A = l²      Substitute the value of l

A = 2²

A = 4

(d) Area of MPN

A(MPN) = A(MONP) – A(MON)  

Area(MPN) = 4 - π

Answer:

The areas are equal.

Step-by-step explanation:

Let the first rectangle be R and

Answer:

Coordinate of Q (3,4)

Step-by-step explanation:

Let to points S(-2,-6) and T(5,8)  

Le Q(x,y) be the point in which it divide the ST in the ratio 5:2

If a point (x,y)cut the line in the ratio a : b where the end coordinate are( x1,y1) and (x2,y2)

x = x1 + p/w(x2 - x1) and y = y1 + p/w(y2 - y1)  

where p = a and w = a+b

To find the coordinate of Q

x  = x1 + p/w(x2 - x1 )

x = -2 + 5/7(5 - -2) = -2 + 5=3

y = y1 + p/w(y2 - y1)  

y = -6 + 5/7(8 - -6) = -6 + 10 = 4

Therefore the coordinate of Q is (3,4)

All of the following except a trapezoid

Answer:

A and B.

Step-by-step explanation:

To get to know the graph with least slope, we have to write all equations in the form y=mx + c.

where m is the slope and c is the the y-intercept.

A. y = x + 6

For this equation m = 1

B. y = -x - 9

For equation B, m = -1

C. y = 2x + 1

In this equation, m = 2

D. y = -7x - 2

In equation D, m = -7

The equation with the highest slope is D while the one with the least slope/steep is A and B.

Answer:

Percent increase is 17.6%

We still have to pay 7.50 with the coupon

Step-by-step explanation:

Percent increase = (new- original)/original *100%

                             = (10-8.5)/8.5 * 100%

                             = 1.5/8.5 * 100%

                             = 17.6470588%

Round to the nearest tenth

                                 17.6%

This is an increase since the cost went up.

If we have 25% off, we still have to pay (100%-25%) = 75%

10 *.75 = 7.50

We still have to pay 7.50 with the coupon
