Answer:

1 m/s2

Step-by-step explanation:

Olive Oyl's weight = 10 × 9.81 = 98.1 N

This weight is a force acting downward because it is due to gravity.

Popeye pulls Olive Oyl up with a force of 108.1 N. Both forces act vertically but in opposite directions. Hence their resultant, R, is their difference and is in the direction of the larger force.

R = 108.1 N - 98.1 N = 10 N

This force causes an acceleration, a, on the mass, m, of Popeye.

R = ma

a = R/m = 10 N/10 kg = 1 m/s2

Answer:

1.01 m/s²

Step-by-step explanation:

From Newton's law of motion,

ma = F-W................ Equation 1

Where m = mass of Olive Oyl, a = acceleration, F = Upward force, W = weight of Olive Oyl.

Also,

W = mg .................. Equation 2

Where g = acceleration due to gravity.

Substitute equation 2 into equation 1

ma = F-mg

make a the subject of the equation

a = (F-mg)/m............. Equation 3

Given: F = 108.1 N, m = 10 kg

Constant: g = 9.8 m/s²

Substitute into equation 3

a = [108.1-(10×9.8)]/10

a = (108.1-98)/10

a = 10.1/10

a = 1.01 m/s²

Hence, Olive Oyl's acceleration = 1.01 m/s²

Answer:

551.8 feet

Step-by-step explanation:

We are given

Adjacent = 1300 feet

Opposite = x

Angle = 23°

We solve using the trigonometric function Tangent

tan θ = Opposite/Adjacent

tan 23 = x/1300 feet

Cross Multiply

x = tan 23 × 1300 feet

x = 551.81726107 feet

Approximately = 551.8 feet

The Length of the building = 551.8 feet

Answer:

The correct answer is 31x + 0.5

Step-by-step explanation:

∵ 13x + 5 + 17x - 4.5 + x

To solve this correctly you must to add the coefficients of the like terms (terms who has same variables or constant terms)

∵ 13x , 17x , x are like terms ⇒ terms with same variable

  (same letters and same power)

∵ 5 , 4.5 are like terms ⇒ constant terms (numbers only)

∴ (13x + 17x + x) + (5 - 4.5) = 31x + 0.5

* <u>The error of first answer:</u>

- 18x + 17x - 4.5 + x

- She add 13x + 5 = 18x ⇒ she add unlike terms

* <u>The error of second answer:</u>

- 35x - 4.5 + x

- She add 13x + 5 + 17x  = 35x ⇒ she add 2 like terms with 1 unlike term

* <u>The error of third answer:</u>

- 30.5x + x

- She add 13x + 5 + 17x - 4.5 = (13x + 17x) + (5 - 4.5) =

  30x + 0.5 ⇒ she add 2 like terms and 2 constant terms

  and then add the 2 unlike answers

* <u>The error of fourth answer:</u>

- 31.5x

- She add 13x + 5 + 17x - 4.5 + x = (13x + 17x + x) + (5 - 4.5) =

  31x + 0.5 ⇒ she add 3 like terms and 2 constant terms

  and then add the 2 unlike answers
