Answer:

There were 12 cookies at the start

Step-by-step explanation:

Since Maximo likes to eat 2 cookies per day, after three days, he would have eaten 6 cookies. There are 6 cookies left after 3 days, so 6(amount he ate) + 6(amount of cookies left) is 12.

Answer:

[tex]y-6=-\frac3{13}(x-5)[/tex]

Step-by-step explanation:

Get the slope of the line between the two points. As usual, [tex]m= \frac{\Delta y}{\Delta x}= \frac{8-(-18)}{4-(-2)}=\frac{8+18}{4+2}=\frac{26}{6}=\frac{13}3[/tex]

You want the perpendicular to it, so take it's inverse and change its sign:

[tex]m_p=-\frac3{13}[/tex]

At this point, it's just using the point-slope form, and you're done - unless you're required to provide the line in a specific way, which usually means just crunching numbers and rewriting the equation

[tex]y-y_0=m_p(x-x_0)\\y-6=-\frac3{13}(x-5)[/tex]

Answer:

y=-3/13x+7.15384615385

Step-by-step explanation:

y=mx+b

We want to find the slope first so will find the slope of the line that is perpendicular to our line.

y2-y1/x2-x1

-18-8/-2-4=

-26/-6=

13/3

The slope of the other line is 13/3

To find the slope of our line we can do the opposite reciprocal of 13/3 which is -3/13.

Let's plug that in with the other values to find y-intercept

6=-3/13*5+b

6=-1.15384615385+b

b=7.15384615385

The linear equation that represents the table is (a) y = 7x +4

How to determine the linear equation

Start by calculating the slope (m) using:

Answer:

11.2

Step-by-step explanation:

15×15-10×10=125

Square root of 125 to the nearest tenth is 11.2

Answer:

1. 35 minutes

2. 12:15 p.m.

3. 110 minutes

4. 6:05 p.m.

5. 9:21 a.m.

Step-by-step explanation:

1. Subtract 2:55 from 3:30 = 35

2. Subtract 25 minutes from 12:40 = 12:15

3. Subtract 7:20 from 9:10 = 110

4. Add 35 minutes to 5:30 = 6:05

5. Subtract 33 from 9:54 = 9:21

x + 75 + x + 125 = 180

2x = 180-75-125

2x = -20

x = -10

Answer:

A/Q

X+75+x+125=180

=>2x+200=180

=>2x=180-200

=>x=-20/2

Hence,the value of x=-10

    Huckabee                        0.19                                     118

    Guiliani                              0.12                                    75

    John McCain                     0.10                                    62

       Ron Paul                         0.04                                    25

  Tom Tancredo                         0.01                                    6

    Undecided votes                   0.28                                 174

Step-by-step explanation:

From the question we are told that

   The  number of voters is  n  =  621

   The  voter  election aspirants  and their relative frequency are

Romney , 0.21

Huckabee , 0.19

Guiliani  ,  0.12

John McCain ,0.10

 Ron Paul , 0.04

Fred Thompson 0.04,

Duncan Hunter 0.01

Tom Tancredo 0.01

Undecided votes 0.28

This undecided vote is used to represent votes that did not count and it is obtained by subtracting the other relative frequencies  from  1 (i.e 100%)

Generally the frequency is mathematically represented as

 Romney ,  621 *  0.21  =  130      

Huckabee ,  621 *  0.19    =  118

Guiliani  ,   621 * 0.12 =  75

John McCain      621 * 0.10 = 62

 Ron Paul , 621 * 0.04  =  25

Fred Thompson 621 * 0.04 =  25

Duncan Hunter 621 *  0.01  = 6

Tom Tancredo 621 * 0.01 =  6

Undecided votes 621 * 0.28 =  174

So the table is  

    Voters                 Relative Frequency                Frequency

   Romney                            0.21                                     130      

    Huckabee                        0.19                                     118

    Guiliani                              0.12                                    75

    John McCain                     0.10                                    62

       Ron Paul                         0.04                                    25

 Fred Thompson                    0.04                                     25

  Duncan Hunter                      0.01                                      6

  Tom Tancredo                         0.01                                    6

    Undecided votes                   0.28                                 174

Answer:

x=12

Step-by-step explanation:

Let's solve your equation step-by-step.

2x+8+5x−2=90

Step 1: Simplify both sides of the equation.

2x+8+5x−2=90

2x+8+5x+−2=90

(2x+5x)+(8+−2)=90(Combine Like Terms)

7x+6=90

7x+6=90

Step 2: Subtract 6 from both sides.

7x+6−6=90−6

7x=84

Step 3: Divide both sides by 7.

7x7=847

x=12

Answer:

  12

Step-by-step explanation:

The constant of proportionality is the slope of the line, the ratio of the y-coordinate to the x-coordinate.

  k = 36/3 = 12 . . . . . from the lower left point (not the origin)

__

Additional comment

This comes from the equation for a proportion:

  y = kx

Solving for k, we get ...

  k = y/x

A proportion always graphs as a line through the origin. The slope of it is k, the constant of proportionality.

Answer: 6042.23

Step-by-step explanation:

P0=d(1−(1+rk)−Nk)(rk).

We have P0=$1,200,000,r=0.0195,k=12,N=20, so substituting in the numbers into the formula gives

$1,200,000=d(1−(1+0.019512)−20⋅12)(0.019512),

that is,

$1,200,000=198.602327d⟹d=

The total interest payable is $4,68,000.

Given,

An executive wishes to take out a $1,200,000 mortgage.

The yearly interest rate on the loan is 1.95% and the loan is for 20 years.

Payments will be made monthly.

Calculate the total interest payable.

Round your answer to the nearest thousand dollars.

It is given by:

SI = (P x R x T) / 100

P = principal amount

R = rate

T = time

We have,

P = $1,200,000

R = 1.95%

T = 20 years

SI = (P x R x T) / 100

SI = (1200000 x 1.95 x 20) / 100

SI = (1,200,000 x 195 x 20) / 100 x 100

SI = 120 x 195 x 20

SI = $4,68,000

Thus the total interest payable is $4,68,000.

Answer:

36 square units

Step-by-step explanation:

A 2x2 square has sides that are 2 units long.

When you dilate by a factor of 3, each side has a length 3 times the original length. 2 * 3 = 6. Each side is now 6 units long.

area = side * side = 6 units * 6 units = 36 units^2

Answer:

Before solving these, we must know;

· A 90° angle forms a right angle.

· A 180° angle forms a straight angle.

· Any angle greater than a 90° angle is considered an obtuse angle (x > 90 = obtuse).

· Any angle less than a 90° angle is considered an acute angle (x < 90 = acute).

Now just eyeing these, I can tell that;

1. Is acute, because it looks like it is smaller than a 90° angle(right angle).

2. Is straight, because it looks fairly like a straight line(which measures 180°).

3. Is obtuse, because it looks greater than a 90° angle(right angle).

4. Is right, because it looks exactly like a 90° angle(right angle).
