PLEASE HELP HELP. I don’t get the 8 and 9

Answer: C.  [tex]\dfrac{1}{3}[/tex]

Step-by-step explanation:

Given: Box contains 8 green balls and 4 purple balls.

Total balls = 8+4 = 12

event 1 = first picking green ball

event 2 = second picking purple balls.

As first ball was replaced, that means both events are independent.

Probability that you have selected a green ball and then a purple ball = P(purple ball )

Formula for probability = [tex]\dfrac{\text{favorable outcomes}}{\text{total outcomes}}[/tex]

Probability of selecting a purple ball (second pick)= [tex]\dfrac{4}{12}[/tex]

[tex]=\dfrac{1}{3}[/tex]

The required probability [tex]=\dfrac{1}{3}[/tex], so C is correct option.

Answer:

x > -22/7

Step-by-step explanation:

To find out which inequality is is equivalent, you solve for x.

-4(x+7) < 3(x-2): distribute variables

-4x-28 < 3x-6: Add 6 to both sided

-4x-22 < 3x: add 4x to both sides

-22 < 7x: divide by 7

-22/7 < x: you can switch sides if prefered but you have to switch sign too

x > -22/7

Answer:

308m

Step-by-step explanation:

11+22+33+44+55+66+77=308

Total price after 6 years in Account I is :

[tex]P _1=P_o+\dfrac{P_ort}{100}\\\\P_1=200+\dfrac{200\times 4.5 \times 6}{100}\\\\P_1=\$254[/tex]

Total price after 6 years in Account II is :

[tex]P_2=P_o(1+\dfrac{r}{n})^{nt}\\\\P_2=150(1+\dfrac{3.34}{1})^{1\times 6}\\\\P_2=\$1002373.64[/tex]

Total balance, [tex]T=P_1+P_2=1002373.64+254=\$1002627.64[/tex]

Hence, this is the required solution.

Answer:

36.16 miles

Step-by-step explanation:

A recycling truck begins its weekly route at the recycling plant at point A, as pictured on the coordinate plane below. It travels from point A to point B, then points C, D, and E, respectively, before returning to the recycling plant at point A at the end of the day. The truck’s route is illustrated on the coordinate plane below. If each unit on the coordinate plane represents one mile, what is the total distance the truck travels on its route?

Answer:

The distance between two points X([tex]x_1,y_1[/tex]) and Y[tex](x_2,y_2)[/tex] is given as:

[tex]|XY|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

From the image attached, the coordinates of the plane are:

A(-1, -1), B(1, -1), C(5, 2), D(0,  13), E(-5, 2).

The lengths are:

[tex]|AB|=\sqrt{(1-(-1))^2+(-1-(-1))^2}=2\ units\\ \\|BC|=\sqrt{(5-1)^2+(2-(-1))^2}=5\ units\\\\|CD|=\sqrt{(0-5)^2+(13-2)^2}=12.08\ units\\\\|DE|=\sqrt{(-5-0)^2+(2-13)^2}=12.08\ units\\\\|AE|=\sqrt{(-5-(-1))^2+(2-(-1))^2}=5\ units[/tex]

But 1 mile = 1 unit

Total distance = |AB| + |BC| + |CD| + |DE| + |AE| = 2 + 5 + 12.08 + 12.08 + 5 = 36.16 miles

Answer:

s² - 225 = 0

Step-by-step explanation:

The product in scientific notation is 1.32 × 10²⁵.

Scientific notation is a method for expressing numbers that are too large or too small to be easily written in decimal form (usually resulting in a long string of digits). It is known as standard form, scientific form, or standard index form. Scientists, mathematicians, and engineers all use this base ten notation because it can simplify some arithmetic operations. It is typically referred to as "SCI" display mode on scientific calculators.

Non-zero numbers are written in the form (m x n¹⁰) in scientific notation.

Given (11 x 10¹¹)(12 x 10¹²)

11 x 10¹¹ x 12 x 10¹²

132 x 10¹¹⁺¹² (base same add powers)

132 x 10²³ (132 can be written as 1.32 x 100)

1.32 x 100 x 10²³

1.32 x  10²³⁺²

1.32 x 10²⁵

Therefore the scientific notation is 1.32 x 10²⁵.

Answer:

42

Step-by-step explanation:

So are is length times width,

since we are dealing with a square, then the length and the width are congruent

so we can say that, for this case:

a = length * length

hence

196 = length^2

14 = length

and

14 = width

since only 3 sides of this square are needed, one only has to multiply the length by 3

14 * 3

=42

so only 42 meters of fencing are needed

Answer: Joseph could use C), D), and E) to make kebabs without any leftovers:

C) 30 pieces of meat and 40 pieces of vegetables

D) 45 pieces of meat and 60 pieces of vegetables

E) 72 pieces of meat and 96 pieces of vegetables

How were the answers determined? To solve for the answer, here are some pointers:

   Consider the given which states that each kebab has 3 pieces of meat and 4 pieces of vegetables, and Joseph wanted to make kebabs without any leftovers - meaning, there should be no extra piece of meat or no extra piece of vegetable.

   In choosing which is the answer, make sure that the number of pieces of meat must be divisible by 3 (pieces of meat), and the number of pieces of vegetables must be divisible by 4 (pieces of vegetables). This was also based on the given.

   Moreover, the quotient for meat and the quotient for vegetables must be equal to each other so that there will be no leftovers.

   Therefore, the answers are C), D), and E) because these three answers satisfy the conditions abo

Answer:

[tex]\boxed {x = -4}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]9(5 - x) = 81[/tex]

-Use Distributive Property:

[tex]9(5 - x) = 81[/tex]

[tex]45 - 9x = 81[/tex]

-Subtract [tex]45[/tex] to both sides:

[tex]45 - 45 - 9x = 81 - 45[/tex]

[tex]-9x = 36[/tex]

-Divide both sides by:

[tex]\frac{-9x}{-9} = \frac{36}{-9}[/tex]

[tex]\boxed {x = -4}[/tex]

So, the value of [tex]x[/tex] is [tex]-4[/tex].
