The potential energy of an object is jointly related with the mass of the object and the height of the object. A 40-kg object is 2 meters off the ground. The potential energy of the object is 784 joules. A 10-kg object is 3 meters off the ground. What is the potential energy of the 10-kg object?

Answers

the answer is c. 294 joules

Answer:

The potential energy of the 10-kg object is 294 joules .

Step-by-step explanation:

As given

The potential energy of an object is jointly related with the mass of the object and the height of the object.

Let the potential energy of an object is denoted by P.E .

Mass of the object = m

Height of the object = h

Than

[tex]P.E \propto mh[/tex]

P.E = mgh

Where g is the accleration due to gravity .

As given

A 40-kg object is 2 meters off the ground. The potential energy of the object is 784 joules.

Put the value in the P.E = mgh

784 = g × 2 × 40

784 = 80g

[tex]g = \frac{784}{80}[/tex]

g = 9.8 joules per kg meter .

As given

A 10-kg object is 3 meters off the ground.

Put the value in  P.E = mgh

P.E = 10 ×  9.8 × 3

P.E = 294 joules

Therefore the potential energy of the 10-kg object is 294 joules .

Read the numbers and decide what the next number should be 8,4,2,6,3,2,4.

Answers

Final answer:

The given sequence involves a two-part pattern. One part is halving the previous number and the other part alternates between 4 and 6. Considering the pattern, the next number should be 0.5.

Explanation:

The sequence 8,4,2,6,3,2,4 appears to have a pattern. It seems to be a two-part pattern that alternates. The first part, observed in the numbers 8, 2, and 2, is halving (8 divided by 2 is 4, and 2 divided by 2 is 1, and 1 by 2 is 0.5). Then, the second part, observed in 4,6,4, seems to alternate between 4 and 6. So, if the pattern continues, the next number after 4 should be 0.5 from the first part of the pattern.

#SPJ11

Final answer:

The sequence could actually be representing two series - one series is halving the number (8 to 4 to 2) and the other is multiplying each number by 2 (3 to 2 to 4 to 8). Thus, the next number could either be 1 (if we continue the halving series) or 12 (if we continue the multiplying by 2 series).

Explanation:

The number sequence provided seems to be made of two different series interwoven. One series is halving each number (8 to 4 to 2), and the other series is multiplying each number by 2 (2 to 4 to 6 to 12).

Therefore, the next number after 8, 4, 2, 6, 3, 2, 4 should be 1 (half of 2) whereas the next number in the second series after 6, 3, 2, 4 should be 12 (four times 3). So, depending on which pattern the sequence is following, the next number could be either 1 or 12.

A store is having a 10% off sale. It gives an additional 20% off for an item that is above $100 after the first 10% discount.A jacket costs $124.99
if you buy the jacket, how much will you save in total?
*SHOW WORK* ...?

Answers

Final answer:

To calculate the total amount saved when buying a jacket at a store with a 10% discount and an additional 20% discount, follow these steps: find the savings from the first discount, calculate the price after the first discount, check if the price is above $100, calculate the additional discount, and add both savings together. In this case, the total amount saved is $34.9972.

Explanation:

To calculate the total amount saved, we need to use the following steps:

Find the total savings from the first 10% discount: $124.99 * 0.10 = $12.499Find the price of the jacket after the first discount: $124.99 - $12.499 = $112.491Check if the price is above $100. If it is, calculate the additional 20% discount: $112.491 * 0.20 = $22.4982Add the savings from the additional discount to the previous savings: $12.499 + $22.4982 = $34.9972

So, the total amount saved is $34.9972.

Final answer:

To find the total amount saved, apply the discounts and add the amounts together. The total amount saved is $35.00.

Explanation:

To find the total amount saved, you need to calculate the discount for each discount percentage. First, apply the 10% discount to the original price of the jacket:
10% of $124.99 = $12.499.
Next, apply the 20% discount to the price after the first discount:
20% of ($124.99 - $12.499) = 20% of $112.491 = $22.4982.

Finally, add the two discounts together to find the total amount saved:
$12.499 + $22.4982 = $34.9972.

Rounding to the nearest cent, the total amount saved is $35.00.

what are the translation rules in geometry?

Answers

The original object and its translation have the same shape and size, and they face in the same direction. A translationcreates a figure that is congruent with the original figure and preserves distance (length) and orientation (lettering order). A translation is a direct isometry.

Final answer:

The translation rules in geometry involve moving every point in a figure the same distance and direction. For a horizontal translation, add or subtract the same value from the x-coordinate of each point. For a vertical translation, add or subtract the same value from the y-coordinate of each point.

Explanation:

In geometry, translation is a transformation that moves every point in a figure the same distance and direction. The translation rules involve determining the new coordinates of the translated figure.

The translation rules in geometry can be summarized as:

For a horizontal translation, add or subtract the same value from the x-coordinate of each point.For a vertical translation, add or subtract the same value from the y-coordinate of each point.

For example, if you have a point with coordinates (2, 3) and you want to translate it 3 units to the right and 2 units up, you would add 3 to the x-coordinate and 2 to the y-coordinate to get the new coordinates of the translated point: (5, 5).

Linda Frankell pays $50.00 a month for group health insurance. There is a $300 deductible. Her medical bills for the last year were $2,600.00. Linda's insurance company provided payment of 80% of the bills less the deductible.

What was the insurance company's payment? $

What was Linda's total cost (including the monthly premium)? $

Answers

Linda Frankell Pays $50.00 a month towards group health insurance, so for a year, that is for 12 months, her premiums would be

Linda's premiums for 12 months = $50 × 12 = $600

Deductible is the amount Linda Frankell will have to pay each year as a policy holder towards her medical expenses before the insurance company pays its share.

Amount Linda pays towards deductible = $300

Linda's medical bills = $2,600.00
The insurance company will pay 80% of the bills less the deductible, which means, the insurance company will pay 80% of the ($2,600.00 - $300 deductible = $2,300.00)

∴ Amount the insurance company pays = 80% of $2,300.00 = $1,840.00

Amount Linda has to pay towards the $2,300.00 = $2,300.00 - $1,840.00 = $460.00

Linda's total cost = Linda's 12 months premiums + $300 deductible + $460 = $600 + $300 + $460 = $1,360.00

Insurance company's payment = $1840.00
Linda's total cost = $1,360.00

Answer:

10.

Step-by-step explanation:

We are asked to find the estimation of 492.6 divided by 48.

First of all, we will round 492.6 to nearest hundreds and 48 to nearest tens.

Since tens digit of 492.6 is greater than 5, so we will round up to nearest hundred as: [tex]492.6\approx 500[/tex]

Since ones digit of 48 is greater than 5, so we will round up to nearest tens as: [tex]48\approx 50[/tex].

Now, we will find the quotient as:

Ella is 8 years old. and given that is 4 years younger. then Lian is 12

Answer:

Lian is 12 years old and Ella is 8 years old.

Step-by-step explanation:

Lian and her younger sister Ella are 4 years apart.

The sum of their ages is 20.

Let L be Lian’s age in years.

Let E be Ella’s age in years.

The system of linear equations that models the scenario is:

[tex]L-4=E[/tex] this gives [tex]L=E+4[/tex]

[tex]L+E=20[/tex]

Putting L=E+4 in the second equation

[tex]E+4+E=20[/tex]

[tex]2E=20-4[/tex]

[tex]2E=16[/tex]

So, [tex]E=8[/tex]

Now we have , L+E=20

[tex]L+8=20[/tex]

So, [tex]L=12[/tex]

Therefore, Lian is 12 years old and Ella is 8 years old.

tan inverse cos x/1-sin x
write in simplest form? ...?

Answers

tan [arccos(x) ] / [1 - sin(x) ]

1) First work the numerator, which is the confussing part

x = cos(y) =>  arccos(x) = y

tan [arccos(x) ] = tan (y) = sin (y) / cos (y)

using the fundamental identity

[cos(y)] ^2 + [sin(y)}^2 = 1 => sin (y) = √(1 - [cos(y)]^2 ) = √(1 - x^2)

=> tan (y) = sin(y) / cos(y) = √(1-x^2) / x  ... this is the numerator

2) write the complete fraction using the numerator just found

[√(1 - x^2) / x] / (1 - sin(x) ) = √(1 - x^2) / [x (1 - sin(x) ]

Answer: √(1 - x^2) / [x (1 - sin(x) ]

Express 31% as a fraction in its lowest form

Answers

31 ------ 100 that's is what I got in the lowest form x
Final answer:

To express 31% as a fraction in its lowest form, divide 31 by 100 and simplify the resulting fraction.

Explanation:

To express 31% as a fraction in its lowest form, we need to convert the percent to a decimal first. We do this by writing 31% as a fraction with a denominator of 100 and dividing the numerator by the denominator: 31/100. To reduce the fraction to its lowest form, we find the greatest common divisor (GCD) of the numerator and denominator, which is 1. Dividing both the numerator and denominator by 1, we get the fraction 31/100 in its lowest form.
