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
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)

A line passes through the point (-8,7) and has a slope of 5/4 write equation in slope intercept form
Answer:
[tex]y=\frac{5}{4} x[/tex]+17
Step-by-step explanation:
Okay for this you take the point (-8+7) and plug it into the equation getting you this 7=[tex]\frac{5}{4}[/tex](-8)+b
If you multiple [tex]\frac{5}{4\\}[/tex] by -8 you get -10
You then add -10 to the other side to get 17
that means 17=b
meaning you get [tex]y=\frac{5}{4} x[/tex]+17 by plugging in 17 to b

Round 9,99975 to the nearest thousand.
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.
2. There are 12 high schools competing in a basketball tournament. In how many ways can the teams be placed
(1º, 2nd, .., 12th) at the end of the tournament?
Answer:
The teams can be placed in 479,001,600 ways.
Step-by-step explanation:
To solve this question, we want to know in how many ways 12 elements can be arranged.
Number of possible arrangements of x elements:
The number of possible arrangments of x elements is given by:
[tex]A_{x} = x![/tex]
In this question:
12 teams, so arrangment of 12 elements.
[tex]A_{12} = 12! = 479001600[/tex]
The teams can be placed in 479,001,600 ways.
