Ronnie, Mack, Kim, and Ada together stacked a total of 40 pizzas in a pan. Ronnie stacked 0.25 of the pizzas, Mack stacked 9 of the 40 pizzas, Kim stacked 35% of the pizzas, and Ada stacked the remaining pizzas. Who stacked the most pizzas?

Answers

Hello!

Here's how much each person stacked:

Ronnie -- 0.25 of the 40 pizzas.

Mack -- 9/40

Kim -- 35% of the 40 pizzas.

Ada -- rest of the pizzas.

Now, the questions asks for who stacked the most pizzas.

First, find our how many pizzas they stacked out of 40.

40 × 0.25 = 10

40 × 35% = 14

10 + 9 + 14 = 33

40 - 33 = 7

This means that Ronnie stacked 10 pizzas, Mack stacked 9 pizzas, Kim stacked 14 pizzas, and Ada stacked 7 pizzas.

ANSWER:

Kim stacked the most pizzas since she stacked 14 of them.

Answer:

Kim stacked the most pizzas since she stacked 14 of them.

The acceleration due to gravity is the constant of variation. What is the acceleration due to gravity of a falling object? 4.9 9.8 10.2 19.6

Answers

Final answer:

The acceleration due to gravity on Earth is approximately 9.80 m/s² and is symbolized as g, which represents a constant rate of acceleration for free-falling objects in the absence of air resistance.

Explanation:

The acceleration due to gravity is a constant that plays a fundamental role in physics, particularly when discussing free-fall motion. On Earth, the acceleration due to gravity of a falling object, when air resistance is negligible, is approximately 9.80 m/s². This value, denoted by the symbol g, is used to calculate various parameters in the kinematic equations of motion for an object subject only to the force of gravity.

There are 19.6.grams of protein in 4 ounces of cashews. About how many gram of protein are in one ounce of cashews?

Answers

19.6 / 4 will give you 1 ounce. It's about 5 if you round 19.4 to 20
If you use a calculator, it is 4.9 grams.

Final answer:

To find the protein content in one ounce of cashews, divide 19.6 grams by 4 ounces, resulting in approximately 4.9 grams of protein per ounce.

Explanation:

To find out how many grams of protein are in one ounce of cashews, we need to divide the total amount of protein by the number of ounces. Given that there are 19.6 grams of protein in 4 ounces of cashews, we can calculate the amount of protein in one ounce by performing the following calculation:

Amount of protein in one ounce = Total grams of protein / Number of ounces

Amount of protein in one ounce = 19.6 grams / 4 ounces

Amount of protein in one ounce = 4.9 grams

Therefore, there are approximately 4.9 grams of protein in one ounce of cashews.

Joint-Serve Prosthetics spends 43% of its total expenses for payroll. It increased its total expenses when it spent $250,000 for robotic assemblers. This changed the allocation for payroll to 38% of total expenses. What were its total expenses after purchasing the robotic assemblers? Hint: First find the total expense before the purchase of robotic assemblers.

Answers

Answer: $2,150,000

Explanation: Let

T = Total expenses of Joint-Serve

Then, before the company acquired robotic assemblers, the expenses allocated for payroll is given by

Expenses for Payroll = 43% of Total Expenses
Expenses for Payroll = 0.43T (1)
(Because 43% = 0.43)

Because the total expenses increased by $250,000 after spending for robotic assemblers, the total expenses = T + 250,000

So, the payroll expense is now calculated as

Expenses for Payroll = 38% of Total Expenses
Expenses for Payroll = 0.38(T + 250,000) (2)
(Because 38% = 0.38 and total expenses = T + 250,000)

By comparing equations (1) and (2),

[tex]0.43T = 0.38(T + 250,000) \\ 0.43T = 0.38T + 0.38(250,000) \\ 0.43T = 0.38T + 95,000 \\ 0.43T - 0.38T = 95,000 \\ \frac{0.05T}{0.05} = \frac{95,000}{0.05} \\ \boxed{T = \$ 1,900,000}[/tex]

Thus, the total expense before the purchase of robotic assemblers is T = $ 1,900,000. Therefore, the total expense after purchasing the robotic assemblers is T + 250,000 = 1,900,000 + 250,000 = $2,150,000

Which equation is the inverse of y = 9x^2 - 4?

Answers

keep in mind that, to get the inverse expression of any relation, we start off by doing a quick switcharoo on the variables, and then solve for "y", so let's do so,

[tex]\bf y=9x^2-4\qquad \stackrel{inverse}{\boxed{x}=9\boxed{y}^2-4}\implies x+4=9y^2 \\\\\\ \cfrac{x+4}{9}=y^2\implies \sqrt{\cfrac{x+4}{9}}=\stackrel{f^{-1}(x)}{y}[/tex]

Final answer:

The inverse of

[tex]y = 9x^2 - 4[/tex]

can be mathematically given by y = +/- sqrt((x + 4) / 9), yet it is not considered a function because it does not pass the horizontal line test.

Explanation:

The inverse of a function flips the x and y values such that each x becomes a y and vice versa. However, it's important to mention that not all functions have an inverse that is also a function. Your provided function,

[tex]y = 9x^2 - 4[/tex]

, is a quadratic function (a type of polynomial function), and it does not have an inverse that can also be called a function because it does not pass the horizontal line test.

Yet, mathematically it can be found by swapping x and y and solving for y. If we do that, we have:

Switch the roles of y and x, we get: x = [tex]9y^2 - 4[/tex].Solving for y, we have: y = +/- sqrt((x + 4) / 9), where "sqrt" denotes the square root.

Again, this is not a function due to the presence of the plus/minus symbol.

The mass in a pendulum clock completes one complete swing in 1.00 s . what is the length of the rod?

Answers

The period of oscillation of a pendulum is
[tex]T=2 \pi \sqrt{ \frac{L}{g} } [/tex]
Where L is the length of the pendulum and [tex]g=9.81 m/s^2[/tex] the gravitational acceleration.
Re-arranging the formula and using T=1.0 s, we find the length of the pendulum:
[tex]L= \frac{T^2g}{4 \pi^2}=0.25 m [/tex]

Final answer:

The length of the pendulum or rod in a pendulum clock that completes one swing in 1.00 seconds is approximately 0.25 meters, or 25 centimeters.

Explanation:

The time taken by the pendulum to complete one full swing is also known as its period, denoted by T. You indicated that in this case the pendulum completes one swing in 1.00 seconds. To determine the length of the pendulum, or rod, we use the formula for the period of a simple pendulum, T=2π√(L/g), where L is the length of the pendulum and g is the acceleration due to gravity (approximately 9.8 m/s² on Earth).

Setting T to 1.00 seconds and g to 9.8 m/s², we can solve this equation for L:

L = (T² * g) / 4π²

Substituting the given values:

L = (1.00² * 9.80) / 4π²

This gives us a pendulum length of approximately 0.25 meters, or 25 centimeters.

In preparation for the Senior Prom, 8 seniors got together and decided to travel in style and rent a limousine. They investigated and found a company that would rent the limousine for a minimum charge of $180 for the first 3 hours and $30 per hour thereafter. They estimated that they needed to be picked up at 8:00 p.m. and be back by 1:00 a.m. How much money would each student have to pay if they planned to leave the limousine driver a $20.00 tip?

Each student would have to pay__________.

Answers

First we need to calculate the total cost.

The seniors will rent limousine from 8:00 pm till 1:00 am. So total time of rent = 5 hours

Total charges = Charges of first 3 hours + Charges of next 2 hours + Tip
So,
Total charges = $180 + 2($30) +$20 = $260

Thus the total amount the 8 seniors will have to pay is $260. The amount each senior will have to pay is $260/8 = $32.5

Therefore, each student will have to pay $32.5

Final answer:

Manny's available credit is $2,749.00.

Explanation:

To find Manny's available credit, we need to subtract the total of his purchases from his line of credit. Manny's purchases total $425.36 + $358.33 + $377.11 + $90.20 = $1,251.00. So, to find his available credit, we subtract $1,251.00 from his line of credit of $4,000.00. The available credit is $4,000.00 - $1,251.00 = $2,749.00.
