The cost of 3 loaves of bread and 3 gallons of milk is $19.35. The cost of 4
loaves of bread and 2 gallons of milk is $17.90. How much does one loaf
of bread cost?

Answers

Answer 1

Answer:

bread $2.5   milk  $3.95

Step-by-step explanation:

b=bread    m= milk

3b +3m = 19.35

4b+2m= 17.90

 Multiply the first by  (-2)

 Multiply the second  by 3

    Then add both

              -6b -6m = -38.7

               12b+6m=53.7

     (when you add both  6m is cancelled)

           6b = 15

         b=  2.5     (BREAD $2.5)

4(2.5) = 10

 10+ 2m = 17.90

2m = 7.90

m= 3.95   (MILK $3.95)

Diego predicts that his basketball team has two third probability of winning each of their next seven games select two ways Diego could accurately simulate the number of games his team will win
A , put the number 0 through 7 in a bag pick a number from the back
B, will a standard number cube 7 times count the number of twos
C, roll a standard number cube 7 times count how many of ones to threes and fours
D, Marcus spinner with 12 equally sized sections right when on four of the sections spin the spinner seven times and count the number of times it ends on the win
E, put 10 white chips and fiber chips in a bag draw a chip from the bag record its results and put it back in the bag do the seven times and count the total number of white chips drawn

Answers

Answer:

C and D

Step-by-step explanation:

Both have a 2/3 chance of success, and are completed 7 times :)

let me know if you need more explanation

Options (C) and (D) are same as Diego predictions.

What is probability?

Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.

For the given situation,

Diego predicts that his basketball team has two third probability of winning each of their next seven games.

The probability of winning = [tex]\frac{2}{3}[/tex]

We need to choose from the option, which has the same probability as above.

Option A:

Put the number 0 through 7 in a bag pick a number from the back.

Here, the probability = [tex]\frac{1}{8}[/tex] and the process is done for one time only.

So, this option is not same as above.

Option B:

Will a standard number cube 7 times count the number of twos.

Here, the probability = [tex]\frac{1}{6}[/tex]

So, the option is not same as above.

Option C:

Roll a standard number cube 7 times count how many of ones to threes and fours.

Here, the probability = [tex]\frac{4}{6}[/tex]

⇒ [tex]\frac{2}{3}[/tex]

So the option is same as above.

Option D:

Marcus spinner with 12 equally sized sections right when on four of the sections spin the spinner seven times and count the number of times it ends on the win.

Here, the probability = [tex]\frac{8}{12}[/tex]

⇒ [tex]\frac{2}{3}[/tex]

So the option is same as above.

Option E:

Put 10 white chips and fiber chips in a bag draw a chip from the bag record its results and put it back in the bag do the seven times and count the total number of white chips drawn.

Here, number of fiber chips is not given.

So, we could not predict the probability for this option.

Hence we can conclude that options (C) and (D) are same as Diego predictions.

Pretty simple honestly.

But school ends!

Each side and each area were calculated using the Pythagoras theorem.

What is the Pythagoras theorem?

The Pythagoras theorem states that, in a right triangle, the sum of squares of shorter sides is equal to the square of the hypotenuse.

So, using the Pythagoras theorem

[tex]TU^2=175^2-79^2[/tex]

[tex]TU^2=24384[/tex]

[tex]TU=156.15[/tex]

So, the corresponding area of the rectangle = 156.15*79 =12335.85 square units.

Similarly, [tex]GH = \sqrt{207^{2}-98^2 }[/tex]

[tex]GH=182.33[/tex]

So, the corresponding area of the triangle = 0.5*182.33*98 = 8934.27 square units.

Thus, each side and each area were calculated using the Pythagoras theorem.

G = (-5,-5)

Step-by-step explanation:

d = sqrt (x^2 - x^1)^2 + (y^2 - y^1)^2

Let's use the coordinate pairs: (6,4) and (6,-5).

Input.

d = sqrt (6 - 6)^2 + (-5 - 4)^2

Solve.

d = sqrt 0 + (-9)^2

d = sqrt 0 + 81

d = sqrt 81

d = 9

Count 9 places back from (6, -5) , then you will arrive at (-5,-5).

Thus, the fourth vertex of the rectangle "EFGH" is (-5,-5) for G.
