Answer:

c)1200

Step-by-step explanation:

Given: Students were packed shoulder to shoulder in a gym for a pep rally. The students were in a rectangular shaped area of [tex]7500[/tex] ft.

To Find: If each student on average took up a circular space with a diameter of [tex]2.5[/tex] ft what is the best estimate for the number of  students at the pep rally.

Solution:

Consider the figures attached

A student took up a circular space, if they were packed in rows each student acquired a circular space of [tex]2.5[/tex] ft and left some unused area as given in figures

Now,

Area acquired by a student is a square of side [tex]2.5[/tex] ft as given in figure

Area acquired by single student[tex]=(\text{length of square})^2[/tex]

                                                     [tex]=2.5\times2.5[/tex]

                                                     [tex]6.25\text{sq.ft}[/tex]

Total number of students            [tex]=\frac{\text{total area of rectangular gym}}{\text{area acquired by single student}}[/tex]

                                                     [tex]\frac{7500}{6.25}[/tex]

                                                     [tex]1200[/tex]

there are approximately [tex]1200[/tex] students in gym hence option b is correct.

Answer:

The cost of the shirts are $40 and $24

Step-by-step explanation:

Let

x ----> the cost of one shirt

y ----> the cost of the other shirt

we know that

[tex]x+y=64[/tex] ----> equation A

I assume that the cost x is greater than the cost y

so

[tex]x-y=16[/tex] ----> [tex]x=y+16[/tex] ---> equation B

solve the system by substitution

substitute equation B in equation A

[tex]y+16+y=64[/tex]

solve for y

[tex]2y=64-16[/tex]

[tex]2y=48[/tex]

[tex]y=\$24[/tex]

Find the value of x

[tex]x=y+16[/tex] ---->  [tex]x=24+16=\$40[/tex]

therefore

The cost of the shirts are $40 and $24

Answer:

Infinitely many solutions.

Step-by-step explanation:

10+x=5(1/5x+2)

10+x=x+10

infinitely many solutions

The equation 10+x=5(1/5x+2) has an infinite number of solutions.

To solve the equation 10+x=5(1/5x+2), we need to simplify both sides and then isolate the variable x. Let's start by distributing the 5 to the terms inside the parentheses.

10+x = 5(1/5x+2) becomes:

10+x = 1x+10

Next, we can combine like terms on each side of the equation. Subtracting x from both sides:

10 = x+10-x

The x terms cancel out, leaving us with:

10 = 10

This equation is always true, which means that there are an infinite number of solutions.

Answer:

a) $13588.08

b) $688.08

Step-by-step explanation:

Melissa had to purchase $12,900 worth of machinery for her business.

She made a down payment of $2100 and after that made monthly payments of $478.67 for the business loan for the rest.

Given that after years of paying monthly payments of $478.67, she finally paid off the loan.

Assume that she took 2 years to repay the loan.

a) Therefore, the total amount Melissa ended up paying for the machinery was $[2100 + (478.67 × 24)] = $13588.08 (Answer)

b) Therefore, the amount of interest that Melissa pay on the loan is $(13588.08 - 12900) =$688.08. (Answer)

[tex]m=\frac{-9-6}{-4-2}[/tex]

[tex]m=\frac{-15}{-6}[/tex]

simplify

[tex]m=\frac{5}{2}[/tex]

Answer:

A) 1/4 min

Step-by-step explanation:

Find the equation for the graph:

y = mx + b

Find the slope using two random points (0, 360) and (5, 0)

m = (y2 - y1) / (x2 - x1)

m = (0-360) / (5-0)

m = -360/5

m = -72

b is 360, the y-intercept.

Substitute m= -72 and b=360 into slope-intercept form.

y = -72x + 360

x represents time and y represents the total amount of water at the time.

We are looking for when only 18 liters were drained.

360 - 18 = 342  <= Total amount of water when 18 liters are drained

Substitute 342 for y in the equation and isolate x.

342 = -72x + 360

-18 = -72x

x = 18/72

x = 1/4

Therefore, it will take 1/4 of a minute to drain 18 liters.

Step-by-step explanation:

Answer: 14

Step-by-step explanation:

Answer:

Simple interest = PRT/100

1380 = P x 12 x 2/100

138000 = 24P

Therefore P = 5750 Rs.

Hope this helps!

To find the principal amount given the simple interest, rate, and time, use the formula P = SI / (R × T). Substituting the values, the principal amount is 5750 rupees.

To find the sum of money (principal) using the given simple interest, we can use the simple interest formula:

Simple Interest (SI) = Principal (P) × Rate (R) × Time (T)

Here, we know that:

Rearranging the formula to solve for the principal (P):

[tex]P = \frac{SI }{(R * T)}[/tex]

Substitute the known values:

P = 1380 / (0.12 × 2)

Solving the equation:

P = 1380 / 0.24

P = 5750 rupees

Therefore, the sum of money is 5750 rupees.

Answer:

6x - 3

Step-by-step explanation:

Distribute first.

4x + 6x - 3 - 4x = 10x - 4x - 3 = 6x - 3

The equivalent expression for 4x + 3(2x - 1) - 4x is 6x - 3, achieved by distributing the multiplier in the parenthese and then combining like terms.

The expression 4x + 3(2x - 1) - 4x can be simplified by first distributing the 3 in the term 3(2x - 1), then combining like terms.

1. Distribute the 3 to get : 4x + 6x - 3 - 4x

2. Combine like terms: 6x - 3

So, the equivalent expression of 4x + 3(2x - 1) - 4x is 6x - 3

Step-by-step explanation:

100 divided by 7 is 14.2857142857 km per litres. Then 590 divded by 14.2857142857 is 41.2876137159 or 41.29 rounded

Independent. Two events are dependent if knowing the result of the first one influences what you'd expect from the second.

Consider this example: if I have a sack with 3 black marble and 1 white marble, I have probability 75% of picking a blakc marble, and 25% of picking the white one.

If I pick the white one, and don't replace, the second pick will be dependent on the first one, because now I'm sure that I'll pick one of the black marbles, since they are the only ones left in the sack.

In your example, though, Wendy replaces the marble she picks first. This means that the second pick will take place in the exact same conditions of the first one, and knowing which marble she picked at first doesn't affect in any way the result of the second pick.

As another example, consider rolling two dice. Suppose that the first die lands showing 4. Does this affect in any way what you'd expect from the second die? Well, no: the numbers 1-6 are still equally probable to show up.

Step-by-step explanation:

A = P (1 + k)^t

where A is the final amount,

P is the initial amount,

k is the monthly growth rate,

and t is the number of months.

70 = 50 (1 + k)^3

1.4 = (1 + k)^3

∛1.4 = 1 + k

k = -1 + ∛1.4

k = 0.1187

Answer:

12 and 8

Step-by-step explanation:

12 + 8= 20

12 x 8= 96

The two numbers are 12 and 8. They have a sum of 20 and a product of 96, satisfying the given conditions.

To find two numbers whose sum is 20 and whose product is 96, we can set up a system of equations. Let's call the two numbers x and y.

1. The first equation represents their sum:

  x + y = 20

2. The second equation represents their product:

  xy = 96

Now, we need to solve this system of equations. One way to do it is by substitution. From the first equation, we can express y in terms of x: y = 20 - x.

Now, we substitute this expression for y into the second equation:

x(20 - x) = 96

Expanding and simplifying this equation:

20x - x^2 = 96

Rearranging terms:

x^2 - 20x + 96 = 0

Now, we factor the quadratic equation:

(x - 12)(x - 8) = 0

This gives us two possible solutions for x: x = 12 and x = 8.

So, the two pairs of numbers that satisfy the conditions are (12, 8) and (8, 12). In both cases, the sum of the numbers is indeed 20, and their product is 96, as required.

In summary, the two numbers are 12 and 8, and they meet the criteria of having a sum of 20 and a product of 96. These solutions demonstrate how algebraic techniques can be used to solve real-world problems involving unknown values.

Answer:

The rate of change for each reader is :

For J K Rowling :  17 and a half pages per hour

For R L Stone :  15   pages  per hour

Step-by-step explanation:

Here the reading rate of each reader is given as:

J.K. Reads 35 pages every 2 hours.

So, the number of pages read by J K  in 2 hours  = 35 pages

⇒ The number of pages read per hour  =  35 / 2  = 17 . 5 pages

So, the pages read by J K Rowling in 1 hour is 17 and a half pages.

R L Stone reads 45 pages every 3 hours.

So, the number of pages read by R L  in 3 hours  = 45 pages

⇒ The number of pages read per hour  =  45 / 3  = 15 pages

So, the pages read by R L Stone in 1 hour is 15 pages.

Hence, the rate of change for each reader is :

For J K Rowling :  17 and a half pages  per hour

For R L Stone :  15   pages  per hour

Final answer:

The projectile takes 1.22 seconds to reach its maximum height.

Explanation:

To find the time it takes for the projectile to reach its maximum height, we can use the equation:

where t is the time, v_f is the final velocity, v_i is the initial velocity, and a is the acceleration.

In this case, the initial velocity is 12.0 m/s and the acceleration is -9.8 m/s² (negative because the projectile is moving upward). Since the final velocity at the maximum height is 0 m/s, we can substitute the values into the equation:

t = (0 - 12.0) / -9.8 = 1.22 seconds

Therefore, it takes 1.22 seconds for the projectile to reach its maximum height.
