Calculate the work done. A tractor pulls a heavy log with a force of 100 pounds. The log moves 3 feet.

f = m*a (force equals mass and acceleration)

And since we don't know the actual mass then it's- 100=(m)*3

So when the tractor pulled the log that is, 100 pounds and it only moved 3 feet.

But calculating it (by multiplication) equals to 300 ft-lbs, so therefore it can't be 130 ft-lbs.

So by my guess, it's 300 ft-lbs, since it's impossible and strange to even reach some number as the first and second one.

You deposit $2000 into a savings account to pay 5% interest compounded annually if you make no more deposit or any withdrawal is

Bond [772]

Answer: A = 2000(1.05)^5

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = $2000

r = 5% = 5/100 = 0.05

n = 1 because it was compounded once in a year.

t = 5 years

Therefore, the equation that shows how much money will be in the account after five years is

A = 2000(1 + 0.05/1)^1 × 5

A = 2000(1.05)^5

SSS congruence theorem
SAS congruence theorem
ASA congruence theorem
AAS congruence theorem
HL congruence theorem

================================

Explanation:

SSS stands for "Side side side" indicating there are 3 pairs of sides that are same length. Visually we use tickmarks to show how the sides pair up. Eg: sides that have 1 tickmark only are the same length. If we know that all 3 pairs of sides are congruent, then we have enough info to conclude the triangles are congruent.
SAS means "side angle side". The angle is between the two sides. The sides in question are the ones with tickmarks to indicate how they pair up.
We have two angles and a side between them. So we use ASA this time. It stands for "Angle side angle". This is slightly different from AAS.
We'll use AAS here. The side is not between the two angles. So this is why AAS is different from ASA. Some books may call "AAS" as "SAA", but they're the same thing.
HL stands for hypotenuse leg. This only applies to right triangles (since the hypotenuse is a special term for the longest side of a right triangle). The hypotenuse is always opposite the 90 degree angle. This is the only time when SSA will work. Otherwise, SSA is ambiguous and it is not a valid congruence theorem.

Mrs ndlovu finds the perfect fridge online with the following dimensions: 70inches ×1.7 yards ×2.4 feet will the fridge fit ? sh

Orlov [11]

The dimensions of the fridge are the length, width and the height of the fridge

The volume of the fridge is 123379.2 cubic inches

<h3>How to determine the volume of the fridge</h3>

The dimensions are given as:

70 inches ×1.7 yards ×2.4 feet

Convert the dimensions to inches

70 inches × 61.2 inches × 28.8 inches

So, the volume is:

Volume = 123379.2 cubic inches

Hence, the volume of the fridge is 123379.2 cubic inches
