The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.

Answers

Answer 1

Answers:

team one = 162team two = 108

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

Explanation:

The ratio 3:2 scales up to 3x:2x for some positive whole number x.

This tells us that the first team has 3x people and the second team has 2x people. We'll subtract 12 from the first team and add 12 to the second team to represent 12 people moving.

3x becomes 3x-122x becomes 2x+12

The new team counts 3x-12 and 2x+12 represent team 1 and team 2. Those expressions are in the new proportion 5:4.

This means....

(team 1 new count)/(team 2 new count) = 5/4

(3x-12)/(2x+12) = 5/4

4(3x-12) = 5(2x+12)

12x-48 = 10x+60

12x-10x = 60+48

2x = 108

x = 108/2

x = 54

From this, we then can say:

team 1 original count = 3x = 3*54 = 162team 2 original count = 2x = 2*54 = 108

The two subtotals add to 162+108 = 270 players overall.

If we were to subtract 12 from team 1, and add 12 to team 2, then,

team 1 new count = 162-12 = 150team 2 new count = 108+12 = 120

The ratio 150:120 then reduces to 5:4 when we divide both parts by the GCF 30. This helps confirm we have the correct answer.

Answer 2

Answer:

162 athletes108 athletes

Step-by-step explanation:

Each ratio can be expressed using two numbers that have the same sum. The sum in the first given ratio is 3+2 = 5, and in the second ratio, it is 5+4 = 9. The least common multiple of 5 and 9 is 45, so we can express both ratios so they have a sum of 45:

  3 : 2 = 3(9) : 2(9) = 27 : 18

  5 : 4 = 5(4) : 4(5) = 25 : 20

Here, we observe that the second ratio has numbers that look like 2 was moved from the numerator to the denominator. (27 -2 = 25; 18 +2 = 20) The problem statement tells us 12 athletes were moved, so multiplying the first ratio by 12/2 = 6 will tell us the numbers of players on each original team:

  first team = 27×6 = 162 athletes

  second team = 18×6 = 108 athletes

A middle school has an oval track with the dimensions shown. What is the distance around the track? use 3.14 for π. show your work.

Answers

I think the asnwear is 10859.94
I’m sorry if I’m wrong :{

The distance around the oval track would be 556.9 m which is the sum of the perimeter of the square and the circumference of the semi-circles.

What is the Circumference of a circle?

The Circumference of a circle is defined as the product of the diameter of the circle and pi.

C = πd

where 'd' is the diameter of the circle

We have to determine the distance around the track

The required distance is equal to the sum of the perimeter of the square and the circumference of the semi-circles.

A middle school has an oval track with the dimensions shown.

Here the length of a side of the square = 78 m

And the diameter of the circle = 78 m

the distance around the track = perimeter of  square + circumference of the circle

the distance around the track = 4 × 78 + π × 78 / 2 + π × 78 / 2

the distance around the track = 4 × 78 + π × 78

the distance around the track = (4 + π) × 78

the distance around the track = (4 + 3.14) × 78

the distance around the track = 7.14 × 78

the distance around the track = 556.9 m

Therefore, the distance around the oval track would be 556.9 m.

Carl bought 19 apples of 2 different varieties to make a pie. The total cost of the apples was $5.10. Granny Smith apples cost $0.25 each and Gala apples cost $0.30 each. How many of each type of apple did Carl buy?

Answers

Answer:

Step-by-step explanation:

Split 19 into 2, since Carl bought two types of apples.

19/2 = 9.5

0.25 x 9 = 2.25

0.3 x 9 = 2.7

2.25 + 2.7 = 4.95

5.10 - 4.95 = 0.15

0.3 x 8 = 2.4

2.25 + 2.4 = 4.65

5.1 - 4.65 = 0.45

I think the answer is 7. 5 miles

Answer:

7.5mph (1 d.p)

Step-by-step explanation:

First, I worked out what a third of an hour was to match the unit mph.

60 minutes / 3 = 20 mins

A third of an hour is 20minutes so two thirds of an hour is 40 minutes.

But as we know, one third as a decimal is 0.33(reccuring) so therefore two thirds as a decimal is 0.66, which we need to use.

Now, we need to remember the equation. Speed = distance / time

Place the facts we already know in place.

speed = 5miles / 0.66 (using a calculator.)

speed = 7.5mph (1 d.p)
