2 pie r (m/360)

Answer:

25

Step-by-step explanation:

If you divide by eight, it is equivalent to five cords per minutes.

Now you know that she plays five cords per minute, right?

So you want to multiply five by five, because she plays a total of five minutes.

Answer: b+95+34=180, b+129=180, 51

Step-by-step explanation:

b+95+34=180 works because the angles add to form a straight angle.

From this, we can obtain b+129=180 by adding the two constants.

Subtracting 129 from both sides, we get b=51.

Answer:

[tex]\text Explicit \ Formula :\ a_{n}= 1000\times (\frac{1}{5}) ^{n-1}[/tex]

Step-by-step explanation:

Let [tex]\left( a_{n}\right)[/tex]  be our geometric sequence

The explicit formula for [tex]\left( a_{n}\right)[/tex] is :

 [tex]a_{n}= a_1\times r^{n-1}[/tex]

where r is the common ratio

          a1 is the first term

We notice that :

200/1000 = 1/5

40/200 = 1/5

⇒ r = 1/5

[tex]a_1 = 1000\ \ (given)[/tex]

Conclusion:

[tex]a_{n}= 1000\times (\frac{1}{5}) ^{n-1}[/tex]

Using a system of equations, it is found that she attempted two questions incorrectly.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this question, the variables are:

Sreya scored 30 marks, with 16 correct questions, hence, considering the amount of points for each question, we have that:

2x - y = 30.

Since x = 16:

32 - y = 30

y = 2.

She attempted two questions incorrectly.

Answer:

=> 24m²

Step-by-step explanation:

Area of small rectangle = l×b

=> 2m× 3m

=> 6m²

Area of large rectangle = L×B

=> 9m × 2m

=> 18 m²

Area of figure = area of small rectangle + area of large rectangle

=> 18 m² + 6m ²

=> 24m²

Answer:

Answer:

500 calories an hour are burnt.

Step-by-step explanation:

45 is 3/4 of 60, so 375 is 3/4 of an hour of jogging. If we divide 375 by 3 we will get how many calories are burnt every 1/4 of an hour.

375 / 3 = 125

Now that we know what 1/4 of an hour equals we can add 125, 4 times to find the number of burnt calories in an hour of running.

125 + 125 + 125 + 125 = 500

that means jogging burns 500 calories an hour.

Answer:

x = 23.5

Step-by-step explanation:

By inscribed angle theorem:

[tex](2x + 1) \degree = \frac{1}{2} \times 96 \degree \\ \\ \implies \: (2x + 1) \degree = 48 \degree \\ \\ \implies \: 2x + 1 = 48 \\ \\ \implies \: 2x = 48 - 1\\ \\ \implies \: 2x = 47\\ \\ \implies \: x = \frac{47}{2} \\ \\ \implies \: x = 23.5[/tex]

The percentage of the total cost of 23 separate tickets that George saves by buying a season ticket is 23%.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

As the cost of the separate ticket is £24, and there are a total of 23 games, therefore, the total cost of the 23 games separate ticket can be written as,

=  £24 × 23

=  £552

Now, the cost of the season ticket is £425, therefore, the percentage of the total cost of 23 separate tickets that George saves by buying a season ticket can be written as,

[tex]\rm Percentage = \dfrac{\text{Total cost of 23 seperate ticket}-\text{Cost of season ticket}}{\text{Total cost of 23 seperate ticket}} \times 100\%[/tex]

[tex]\rm Percentage = \dfrac{552-425}{552} \times 100\% = \dfrac{127}{552} \times 100\% = 23\%[/tex]

Hence, the percentage of the total cost of 23 separate tickets that George saves by buying a season ticket is 23%.

Answer:

  $33 per hour

Step-by-step explanation:

"Time and a half" means the overtime rate is 1 1/2 times the base rate.

  overtime rate = (1 1/2) × $22/hour = $(22 +1/2(22))/hour = $33/hour

The correct overtime rate is $33 per hour.

Using it's concept, it is found that there is a 0.183 = 18.3% probability that the person has completed a bachelor's degree and no more.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Researching this problem on the internet, it is found that 529 + 1054 = 1583 out of 1911 + 6730 = 8641 people aged 40 or older have completed a bachelor's degree and no more, hence the probability is given by:

They are asking for a number bigger than zero. But 1 does not work because the answer has to be less than one. Pick any fraction between zero and one.

Answer:

94.1 cm^3 to nearest tenth.

Step-by-step explanation:

Each hour 100 - 10 = 90% of the gas remains.

90% = 0.90.

At 0 hours the volume = 300 cm^3

The equation is

Amount (V) after x hours = 300(0.90)^x.

The amount after 11 hours:

V = 300(0.90)^11

= 94.14

Answer:

y = 300(0.9)^x

94.1 cm³

Step-by-step explanation:

This is an exponential decay.

y = 300(0.9)^x

where x is the number of hours, and y is the amount after x hours.

y = 300(0.9)^11

y = 94.1

As a fraction, it is equal to exactly 792/(2,598,960)

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

Explanation:

The king of spades must be in the hand, and we can pick any other king. There are 3 ways to pick the other king. Then there are 4 C 2 = 6 ways to pick the two queens. The 4C2 refers to the nCr notation. Or you could use Pascal's Triangle.

Overall, there are 3*6 = 18 ways to pick the king of spades, another king, and exactly 2 queens.

Then we have one more card to pick that isn't a king nor a queen. There are 4+4 = 8 cards that are either a king or queen, leaving 52-8 = 44 cards that are neither.

So there are 18*44 = 792 ways to pick a king of spades, another king, exactly 2 queens, and some other card that isn't a king nor queen.

This is out of 52C5 = 2,598,960 possible five card hands.

The probability we're after is roughly 792/(2,598,960) = 0.0003047

Side note: order does not matter with card hands.
