To get on the top players list , don needs to have a minimum average score of 225 after playing four games. His scores on his fi

Black_prince [1.1K]

Average must be 225 or more
4 games so
$\frac{score1+score2+score3+score4}{4} \geq 225$
score1=192
score2=214
score3=250
score4=?
so
$\frac{192+214+250+?}{4} \geq 225$
$\frac{656+?}{4} \geq 225$
times both sides by 4 to clear fraction
656+?≥900
minus 656 from both sides
?≥244

min score is 244

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
