What percent of the pencils in the pack are black?
What fraction of the pencils in the pack is black?

Answers

Answer 1

Answer:

Fraction: 24/30 Percentage: 80%

Step-by-step explanation:

It might want a simplified version of the fraction, so the answer for that one could be 4/5. I hope this helps :)

Answer 2

The percent of the pencils in the pack are black is,

⇒ 80%

And, The fraction of the pencils in the pack is black is,

⇒ 24 / 30

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

Ms. Cathy bought a package of pencils.

And, Out of every 10 pencils, 8 are black. .

Since, There are 30 pencils in the pack,

Hence, The percent of the pencils in the pack are black is,

⇒ 24 / 30 x 100

⇒ 2400 / 30

⇒ 80%

And, The fraction of the pencils in the pack is black is,

⇒ 8 / 10 = x / 30

⇒ 240 = 10x

⇒ x = 24

Thus, The fraction of the pencils in the pack is black is,

⇒ 24 / 30

Thus, The percent of the pencils in the pack are black is,

⇒ 80%

And, The fraction of the pencils in the pack is black is,

⇒ 24 / 30

Answer:

Well on my end i got 47.12, with pi included

Step-by-step explanation:

The surface area of the cylinder with the diameter 2cm and height 15cm  is [tex]100.48 \; cm^2[/tex]

Calculation to find Surface area of cylinder:

Given the diameter of the cylinder is 2cm and height  15cm

Formula :

The surface area of the cylinder =[tex]2\pi r^2+2\pi rh[/tex]

where 'r' is the radius and 'h' is the height of the cylinder

Diameter = 2cm

[tex]radius =\frac{diameter }{2} =\frac{2}{2} =1[/tex]

radius = 1cm and height is 15 cm

the value of pi is 3.14

Substiute all the values

[tex]SA = 2\pi r^2+2\pi rh\\SA=2(3.14)(1)^2+2(3.14)(1)(15)\\SA=6.28+94.2\\SA=100.48 cm^2[/tex]

The surface area of the cylinder with the diameter 2cm and height 15cm  is [tex]100.48 \; cm^2[/tex]

Simplify the expression to lowest terms. 4x^2 - 9/2x^2+11x+12

Answers

Answer:

(2x - 3)/(x +4)

Step-by-step explanation:

Given the expression 4x^2 - 9/2x^2+11x+12

Simplify the numerator

4x^2 - 9 = (2x)^2 - 3^2

Recall that a^2 - b^2 = (a-b)(a+b)

Hence 4x^2 - 9 = (2x - 3)(2x + 3)

The denominator

2x^2+11x+12

Factorize

2x^2+11x+12 = 2x^2+8x + 3x+12

=2x(x + 4) + 3(x + 4)

= (2x + 3)(x + 4)

Hence

4x^2 - 9/2x^2+11x+12 =  (2x - 3)(2x + 3)/(2x + 3)(x + 4)

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

Round 9,99975 to the nearest thousand.

Answers

Answer:

10.00000

Step-by-step explanation:

Answer:

its gonna be 1,000,000

Step-by-step explanation:

When you "round to the nearest thousand regardless of what goes in the blank the steps are nearly always the same:

Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.

Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.

If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.

If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.

MarathonTraining for a marathon takes work and perseverance. It is not something you can do on the spur of the moment. Preparing for a marathon takes months, particularly if you have never run a marathon before. The official distance of a full marathon is 26.2 miles. In 2005, the average time to complete a marathon in the United States was 4 hours 32 minutes 8 seconds for men and 5 hours 6 minutes 8 seconds for women. Most people who run marathons are not trying to win. Many runners try to beat their own best time. Some compare their time to other runners in the same gender and age group. Some people set time-oriented goals, such as finishing under four hours, while others try to complete the race without slowing to a walk. Many beginners simply hope to finish the marathon.Trainers recommend that beginners maintain a consistent running schedule for six weeks prior to even starting a marathon training program. The purpose of this is to allow the body to adapt to the various physical demands of long-distance running. First-time marathon runners should train by running four days a week for at least four months, increasing distance by no more than ten percent weekly. As race day approaches, runners should taper their runs, reducing the strain on their bodies and resting before the marathon. It is important not to overexert yourself during training because that can lead to a lot of injuries. Most common injuries are spraining of the knees and ankles. These sprains can hinder the training.Before the race, it is important to stretch in order to keep muscles limber. Staying hydrating is also important, but there is a danger in drinking too much water. If a runner drinks too much water, he/she may experience a dangerous condition called hyponatremia, a drop of sodium levels in the blood. During the race, trainers recommend maintaining a steady pace. It is normal to feel sore after a marathon. Light exercise will help sore muscles heal faster.Some people run marathons in pairs or groups. Training for and running with another person or group of people can make the experience more enjoyable and more rewarding. A running partner might be just the motivation you need to show up for an early morning run instead of rolling over to hit the snooze button. And, when you cross the finish line together, you can share the satisfaction of reaching your common goal.Usually, thousands of people sign up and run a marathon. Most people finish the race. The thrill of running a marathon for the first time is unbelievable. The training sessions are harder if you have never run before. But it is unbelievable what ones body can do when one puts their mind to it. Having a good coach to support you makes all the difference in training for a marathon.The health benefits you gain from training are tremendous. Your core muscles grow stronger and you will have tighter thighs and gluts. Your heart will be much stronger and you can maintain lower cholesterol and blood sugar levels. Overall you will look better and healthier.Nothing can explain how people feel when they reach that finish line at the end of the race. All the hard work and months of training feel worthwhile. The feeling of accomplishing something great overtakes you. It is great to run a marathon but it is even greater to finish it.Write a sentence summary of the first paragraph in the text. 90% Attempt 1245678910cIf a criminal sentence is commuted it is doubled.Please select the best answer from the choices providedAnswer is F False Read each sentence below.
