A baseball team has won 8 out of the first 20 games and has 40 games remaining. The team needs a winning percentage of 62.5% make the playoffs. How many more wins does the team need in order to get into the playoffs? If the team wins the number of games to get into the playoffs, what is the final win percentage if the team wins 2 and loses 3 games in the playoff?

Answers

Answer:

30 More Games for Playoffs | Win Percentage of 40% in Playoffs

Step-by-step explanation:

We find the total amount of games by adding first 20 and 40 remaining

This will leave us with 60 games

In order to calculate the playoff, we would have to calculate 62.50% in those 60 games.

62.50% is 5/8, we divide 60 by 8 and get 7.50

We multiply both sides by 7.50 and get 37.50/60

We subtract 8 from 37.50 and get 29.50

We round it to the nearest ones and get 30

In order to win the game they would need to win 30 more games

To calculate the final win percentage, we would add 2 and 3, which would give us 5.

After winning 2 and losing 3,

it would give us 2/5,

which in percentage is 40%

Step-by-step explanation:

Step 1: Define

f(x) = 4x + 7

g(x) = f⁻¹(x)

g(15) is x = 15

Step 2: Find inverse

Rewrite: y = 4x + 7Swap: x = 4y + 7Isolate y term: x - 7 = 4yIsolate y: (x - 7)/4 = yRewrite: y = (x - 7)/4Back-substitute: g(x) = (x - 7)/4

Step 3: Evaluate

Substitute: g(15) = (15 - 7)/4Subtract: g(15) = 8/4Divide: g(15) = 2

I hope this helps!

Answer:

14 girls in the class

Step-by-step explanation:

use percentage equation, p = nw or part of the question = the percentage times the total amount.

So in this case our p, or girls in the class (which is part of the total), is unknown. We have the percentage and we have the total. So all we need to do is multipy them. However how do you multiply percentage . . . well 40 percent also equalts to 0.40. So all you have to do is multiply .40 by 35 and you have your answer.

Graph the solution to the following linear equality in the coordinate plane 2x+y>4

Answers

9514 1404 393

Answer:

see below

Step-by-step explanation:

Setting x=0, you can find the y-intercept:

y = 4

Setting y = 0, you can find the x-intercept:

2x = 4

x = 2

The boundary line can be drawn through these intercept points, (0,4) and (2,0). Because the "equal to" case is not included, the boundary line will be dashed.

The y variable is on the open side of the comparison symbol (y>), so the shading is above the boundary line. That is where y-values are greater than those on the line.

What is 35% of 80? use the if/of formula

Answers

Answer:28

Step-by-step explanation:

10%= 8

35%/10%= 3.5

8 x 3.5 = 28

Answer:

Step-by-step explanation:

80/x=100/35

(80/x)*x=(100/35)*x - we multiply both sides of the equation by x

80=2.85714285714*x - we divide both sides of the equation by (2.85714285714) to get x

80/2.85714285714=x

28=x

x=28

now we have:

35% of 80=28

The Extreme Rock Climbing Club planned a climbing expedition. The total cost was $4600, which was to be divided equally among the members going. Prior to the trip,
10 members decided not to go. If the cost per person increased by $230, how many people went on the expedition?

Answers

If you divide the previous cost with the price per person, you would get the number of people who was previously planned to be going, which is 20. That said, with 10 people not going, there would be 10 people left with the price of 2300 to continue the expedition

Let x = number of people that were supposed to go to the trip, where x is greater than or equal to 0.

Let y = price per person initially with x people going on the trip.

xy = 4600

Solve for y.

y = 4600/x

(x - 10)(y + 230) = 4600

Replace y with the fraction 4600/x.

(x - 10)[(4600/x) + 230)] = 4600

What you need to do:

1. Solve (x - 10)[(4600/x) + 230)] = 4600 for x.

2. When you find x, subtract 10 from the value of x to find the number of people that went on the expedition.

You finish.

102 loafs of bread

1232 ÷ 12 = 102.6666666666

102 is the answer

Given that for all values of x,
f(x) = 4x + p
g(x) = px + 1
and fg(x) = 12x + q
where p and q are constants.
Work out the values of p and q.

Answers

Answer:

Step-by-step explanation:

p = 3

M also looking for q.

If f(x) = 4x + p, g(x) = px + 1 and fg(x) = 12x + q. The value of p and q are 4 and 7.

What is Function?

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)

f(x) = 4x + p

g(x) = px + 1

and fg(x) = 12x + q...(1)

So f(g(x)=4(px+1)+p

=4px+4+p...*

Comparing * with (1).

4p=12

P=3

q=4+p

q=4+3

q=7

Therefore p is 3 and q is 7.

a² + b² = c²

Here, a = 4 and c = 7, so plug thes in to find b:

a² + b² = c²

4² + b² = 7²

b² = 49 - 16 = 33
