At the end of the 2nd yr his balance is $440, = I = $14.08
At the end if the 3rd yr his balance is $600, = I = $21.12
$200 is deposited at the beginning of each year
End if the 1st yr SI = PRT/100 = 220 X 3.2 X 1/100 = $7.04
Start of the 2nd yr $220 + $220 = $440
End of the 2nd yr: SI = PRT/100 = 440 X 3.2 X 1/100 = $14.08
Start of the 3rd yr $440 + $220 = $660
End of the 3rd yr: SI = PRT/100 = 660X 3.2 X 1/100 = $21.12
At the end of th2 2nd yr his balance is 440, = I = $14.08
At the end if the 3rd yr his balance is $600, = I = $21.12
HE now has $660 in his account and has earned a total of 42.24 interest over the 3 years.

Sylvia took three times in a video game she scored -120 points during her first turn 320 points in her second time and -80 point
sp2606 [1]
Her average score for the 3 turns is 40 because you have to add all of the scores so -80 and -120 is -200 so add that to 320 and you get 120 divide that by 3 because she took 3 turns and you get 40

For a moving object,When. The force acting on the object varies directly with the object's acceleration. When a force of 64 N ac
Tems11 [23]

Answer:

72 N

Step-by-step explanation:

From the question.

Force is directly proportional to acceleration, with the mass of the object constant.

F α a

F = ka

F₁/a₁ = F₂/a₂....................... Equation 1

Where F₁ = Initial force, a₁ = initial acceleration. F₂ = final force, a₂ = Final acceleration.

make F₂ the subject of the equation

F₂ = (F₁/a₁)a₂................ Equation 2

Given; F₁ = 64 N, a₁ = 8 m/s², a₂ = 9 m/s²

Substitute these values into equation 2

F₂ = (64/8)(9)

F₂ = 72 N

The admission fee at an amusement park is $2.00 for children and $6.80 for adults. On a certain day, 388 people entered the park
san4es73 [151]

Answer: 188 children and 200 adults were admitted

Step-by-step explanation:

Let x represent the number of children that were admitted.

Let y represent the number of adults that were admitted.

On a certain day, 388 people entered the park. It means that

x + y = 388

The admission fee at the amusement park is $2.00 for children and $6.80 for adults. The admission fees collected on that day totaled $1736. It means that

2x + 6.8y = 1736- - - - - - - - - - 1

Substituting x = 388 - y into equation 1, it becomes

2x + 6.8y = 1736

2(388 - y) + 6.8y = 1736

776 - 2y + 6.8y = 1736

- 2y + 6.8y = 1736 - 776

4.8y = 960

y = 960/4.8

y = 200

x = 388 - y = 388 - 200

x = 188
