your team wins 18 medals at a track meet the medals are gold silver and bronze in ratio of 2;2;5. how many of each medal were wo

WITCHER [35]

The team won 4 gold medals, 4 silver medals and 10 bronze medals.

Step-by-step explanation:

Given,

Total medals won = 18

Ratio of gold, silver and bronze = 2:2:5

Let,

x be the original number.

Therefore,

Gold medals = 2x

Silver medals = 2x

Bronze medals = 5x

According to given statement;

$2x+2x+5x=18\\9x=18$

Dividing both sides by 9

$\frac{9x}{9}=\frac{18}{9}\\x=2$

Gold medals = 2x = 2(2) = 4

Silver medals = 2x = 2(2) = 4

Bronze medals = 5x = 5(2) = 10

The team won 4 gold medals, 4 silver medals and 10 bronze medals.

Jerry plays tennis once every 6 days.Sam plays tennis every 10 days and Leo comes once every 12 days.Thus Monday all of them pla

drek231 [11]

Answer:

Friday

Step-by-step explanation:

Given

Jerry = Every 6 days.

Sam = Every 10 days

Leo = Every 12 days.

Required.

If they meet on Monday, when next (day) will they meet

First, we need to get the multiple of 6, 10 and 12.

6 => 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72......

10 => 10, 20, 30, 40, 50, 60, 70, 80.....

12=> 12, 24, 36, 48, 6o, 72, 84, 96......

The common factor between the multiples of 6, 10 and 12 is 60.

This represents the LCM.

It implies that they'll meet on the 60th day after their last meeting on Monday.

To get the day, follow the steps below.

Since there are 7 days a week

So, there are 60/7 weeks in 60 days

60/7 = 8 weeks 4 days

Recall that the last day they met was a Monday.

Hence, there next meeting will be 4 days after Monday.

4 days after Monday = Friday

The table shows the charges for using an internet service. Nicholas use the internet service for 16 hours and 40 Minutes last mo

yanalaym [24]

Answer:

A. Nicholas will have to pay less using plan A

B. He will pay US$ 4 less than plan B

Step-by-step explanation:

Let's compare how much Nicholas will pay on internet service in Plan A and plan B, after using it 16 hours and 40 minutes.

Plan A

Up to 10 hours = US$ 6

Every subsequent 1/2 hour: $1

10 hours + 14 (1/2 hour)

Nicholas will pay 6 + 14 * 1 = US$ 20

Plan B

Up to 12 hours = US$ 4

Every subsequent 1/2 hour: $2

12 hours + 10 (1/2 hour)

Nicholas will pay 4 + 2 * 10 = 24

If sin square theta = 0.75, then cos =

sergeinik [125]

Answer:

$\cos\theta=\pm0.5$

Step-by-step explanation:

Given:

$\sin^2\theta=0.75$

To find $\cos\theta$

Using trigonometric relations for sums and differences of squares of the ratios.

We know:

$\sin^2\theta+\cos^2\theta =1$

Plugging in $\sin^2\theta=0.75$ in the above relation.

$0.75+\cos^2\theta =1$

Subtracting both sides by 0.75.

$0.75+\cos^2\theta-0.75 =1-0.75$

$\cos^2\theta =0.25$

Taking square root both sides.

$\sqrt{\cos^2\theta} =\sqrt{0.25}$

∴ $\cos\theta=\pm0.5$ (Answer)
