the students in mr. juarez's homeroom collected more cans than students in ms. wade's homeroom. write an expression that represents how many more cans were collected.

The four possible times that car B could take to complete one lap are: 120 seconds, 90 seconds, 60 seconds, and 30 seconds.

The equation used to solve this problem is (150 - 30) = N * B, where N is the number of laps and B is the total number of seconds for car B to complete one lap. Therefore, the four possible times for car B to complete one lap are 120 seconds, 90 seconds, 60 seconds, and 30 seconds.

When solving for the total time, it is important to remember that the two cars start the race together and that their speeds remain constant. This means that the time it takes for car B to complete one lap must be a factor of 150 seconds. If car B takes a time that is not a factor of 150, then it will not be able to finish the race in 150 seconds.

Answer:

The volume of one marble can be calculated as follows:

V = (4/3) * π * (r^3)

where r = 1.25 cm (diameter of 2.5 cm divided by 2)

V = (4/3) * 3.14 * (1.25^3) = 5.20 cm^3

The mass of one marble is then:

m = V * 2.6 g/cm^3 = 13.52 g

And the total mass of 66 marbles is:

m = 66 * 13.52 g = 888.32 g

Rounding to the nearest gram, the total mass of the marbles in Keisha's pouch is 888 g.

The rectangular blocks with the measure of 7 cm by 8 cm by 9 cm will not fit in the smallest cylindrical cup with the radius of 5cm.

Rectangular block with the least dimensions, 7cm by 8cm side.

Circle with radius r is x² + y² = r²

∴ x² + y² = 5² or x² + y² = 25

Draw the area of the block using the coordinates (3.5,4) ; (-3.5,4) ; (-3.5,-4) and (3.5,-4)

Its observed that the block cannot fit inside the cup. We can confirm this if

y >4 when x = 3.5

3.5² + y² = 25

12.25 + y² = 25

y² = 12.75

taking positive square root, y≈3.57

Since this is <4, the block cannot fit the 5 cm radius cup.

equation for the cup with r = 6cm,

x² + y² = 6² or x² + y² = 36

Draw the area of the block using the coordinates (3.5,4) ; (-3.5,4) ; (-3.5,-4) and (3.5,-4)

it is observed the block will fit inside the cup as y>4 when x = 3.5

3.5² + y² = 36

12.25 + y² = 36

y² = 23.75

taking positive square roots, y≈4.87

Since this is >4, the block can fit the 6 cm radius cup.

equation for the cup with r = 7cm,

x² + y² = 7² or x² + y² = 49

Draw the area of the block using the coordinates (3.5,4) ; (-3.5,4) ; (-3.5,-4) and (3.5,-4)

it is observed the block will fit inside the cup as y>4 when x = 3.5

3.5² + y² = 49

12.25 + y² = 49

y² = 36.75

taking positive square roots, y≈6.06

Since this is >4, the block can fit the 7 cm radius cup.

∴ the block will not fit the smallest cup

Answer:

Genesis has 126 different outfits to choose from.

Step-by-step explanation:

To calculate the total number of different outfits Genesis can choose, we need to multiply the number of choices available for each article of clothing. So we have:

7 choices for pants

2 choices for t-shirts

3 choices for sweaters or hoodies

3 choices for shoes

To find the total number of outfits, we multiply the number of choices for each category:

7 x 2 x 3 x 3 = 126

Therefore, Genesis has 126 different outfits to choose from.

126 different combination does Genesis have to choose.

We have,

Pants = 7

T shirts = 2

Sweaters or Hoodies = 3

Shoes = 3

So, the number of different combination is

= C(7, 1) x C( 2, 1) x C(3, 1) x C(3, 1)

= 7 x 2 x 3 x 3

= 126 ways

sin70 = x/3.6

x = 3.6sin70

x = 3.4

Answer:

x = 3.4

Step-by-step explanation:

As the given triangle is a right triangle we can use trigonometric ratios to solve for x.

[tex]\boxed{\begin{minipage}{9.4 cm}\underline{Trigonometric ratios} \\\\$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]

From inspection of the triangle:

As we know the angle and the hypotenuse, and wish to find the side opposite the angle, substitute the values into the sine ratio and solve for x:

[tex]\implies \sin(70^{\circ})=\dfrac{x}{3.6}[/tex]

[tex]\implies x=3.6\sin(70^{\circ})[/tex]

[tex]\implies x=3.382893...[/tex]

[tex]\implies x=3.4\; \sf (nearest\;tenth)[/tex]

Therefore, x = 3.4 to the nearest tenth.

The Z score associated with our observation is 2.45. This means that our observed value is 2.45 standard deviations away from the expected value.

2.45

Z score = (Observed value - Expected value) / Standard Deviation

Z score = (95 - 85) / √(85*(1-85)/30)

Z score = 2.45

We can calculate the Z score associated with our observation by taking the observed value, 95%, and subtracting the expected value, 85%, and dividing this by the standard deviation. To calculate the standard deviation, we use the formula: √(expected value*(1-expected value)/sample size). In this case, 85*(1-85)/30. The Z score associated with our observation is 2.45. This means that our observed value is 2.45 standard deviations away from the expected value.

The possible value for the original number is 30

Represent the number with n

So, we have

Lacey = 10 * (n/10 + 1/2)

Euan = 100 * (n/100 + 1/2).

Also, Lacey's new number is 3/4 of Euan's new number, so we have:

10 * (n/10 + 1/2) = (3/4) * (100 * (n/100 + 1/2))

Solving for n, we have:

100 * (n/100 + 1/2) = (4/3) * (10 * (n/10 + 1/2))

Divide through by 100

n/100 + 1/2 = (4/30) * (n/10 + 1/2)

Evaluate

(n + 50)/100 = 4n/300 + 2/30

So, we have

n + 50 = 4n/3 + 20/3

There would be 600 fish after 12 months.

Step-by-step explanation:

The number of fish on the farm increases by 10% each month, so the formula to calculate the number of fish after n months is:

F = 350 * (1 + 0.1)^n

where,

F is the number of fish after n months

We want to find the number of fish after 12 months, so:

The game with 8 minutes of time-outs is 98 minutes long.

What is an algebraic expression?

An algebraic expression is a mathematical phrase that can contain numbers, variables, and operations such as addition, subtraction, multiplication, and division.

In this case, the algebraic expression that represents the length of the soccer game would be:

m = 90 + x

where m represents the total length of the game in minutes, 90 represents the fixed length of the game, and x represents the variable length of time-outs in minutes.

To find the length of the game with 8 minutes of time-outs, we substitute x = 8 into the expression:

m = 90 + 8 = 98

Therefore, the game with 8 minutes of time-outs is 98 minutes long.

To find the probability of randomly withdrawing 5 jellybeans such that at least 2 are red, we need to find the total number of ways to select 5 jellybeans from the bag and then find the number of ways to select 2 or more red jellybeans.

Let's first find the total number of ways to select 5 jellybeans from the bag:

Total number of jellybeans = 4 red + 7 green = 11 jellybeans

Number of ways to select 5 jellybeans from 11 = 11 choose 5 = 462

Next, we need to find the number of ways to select 2 or more red jellybeans:

Number of ways to select 2 red jellybeans = 4 choose 2 = 6

Number of ways to select 3 red jellybeans = 4 choose 3 = 4

Number of ways to select 4 red jellybeans = 4 choose 4 = 1

Total number of ways to select 2 or more red jellybeans = 6 + 4 + 1 = 11

The desired probability is the ratio of the number of favorable outcomes (selecting 2 or more red jellybeans) to the total number of possible outcomes (selecting 5 jellybeans):

P(at least 2 red) = 11/462 = 11/462 = 0.0239 or 2.39%

So, the probability of randomly withdrawing 5 jellybeans such that at least 2 are red is 2.39%.
