lol, just answered my own question.
How many molecules of hydrogen chloride would there be in 100. 00 grams of this gas? please help
Answer:
9.5 * 10^23 molecules of HCl
Step-by-step explanation:
just a note this might be better to put in the chem section next time since this is a stoichiometry question
the molar mass of HCL is 1.007 + 35.45 = 65.457 g/mol
to find the number of moles, divide 100 by 65.457
then multiply the number of moles by 6.22 * 10^23 to get the number of molecules
[tex]100.00g * \frac{1 mol}{65.457g} * \frac{6.22 * 10^{23} molecules }{1 mol} = 9.502 * 10^{23} molecules[/tex]

Nikita performed an experiment in which she randomly pulled a marble from a bag, recorded its color, placed it back in the bag, and then repeated. The results are shown in the following table.
Result Frequency
Red 20
Purple 24
Blue 12
Based on the experiment, what is the probability of drawing a blue marble?
Enter your answer as a fraction, like this: 42/53
The probability of drawing a blue marble is the likelihood of blue marbles
The experimental probability of drawing a blue marble is 3/14
How to determine the probability?The probability of drawing a blue marble is calculated using:
P(Blue) = Blue/Total
So, we have:
P(Blue) = 12/(20 + 24 + 12)
Evaluate the sum
P(Blue) = 12/56
Simplify
P(Blue) = 3/14
Hence, the experimental probability of drawing a blue marble is 3/14

A Diameter of a circle has endpoints P(-10, -2) and Q(4, 6)
a. Find the center of the circle.
b. find the radius. If your answer is not an integer, express in in radical form.
c. write an equation for the circle
PLS HELP FAST!
Will Give Brainiest if answered properly!
Answer:
see explanation
Step-by-step explanation:
(a)
the centre of the circle is at the midpoint of the endpoints.
using the midpoint formula
centre = ( [tex]\frac{-10+4}{2}[/tex] , [tex]\frac{-2+6}{2}[/tex] ) = ([tex]\frac{-6}{2}[/tex] , [tex]\frac{4}{2}[/tex] ) = (- 3, 2 )
(b)
the radius r is the distance from the centre to either of the endpoints
using the distance formula to find r
r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 3, 2 ) and (x₂, y₂ ) = Q (4, 6 )
r = [tex]\sqrt{(4-(-3))^2+(6-2)^2}[/tex]
= [tex]\sqrt{(4+3)^2+4^2}[/tex]
= [tex]\sqrt{7^2+16}[/tex]
= [tex]\sqrt{49+16}[/tex]
= [tex]\sqrt{65}[/tex]
(c)
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r the radius , then
(x - (- 3) )² + (y - 2)² = ([tex]\sqrt{65}[/tex] )² , that is
(x + 3)² + (y - 2)² = 65
Answer:
Step-by-step explanation:
a) Use midpoint formula to find the center.
[tex]\sf \boxed{Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)}[/tex]
P(-10 ,-2) ⇒x₁ = -10 & y₁ = -2
Q(4,6) ⇒ x₂=4 & y₂ = 6
[tex]\sf midpoint = \left(\dfrac{-10+4}{2},\dfrac{-2+6}{2}\right)[/tex]
[tex]=\left(\dfrac{-6}{2},\dfrac{4}{2}\right)\\\\=\left(-3,2\right)[/tex]
b) To find the radius, use the distance formula
[tex]\boxed{distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}[/tex]
Q(4,6) & O(-3,2)
[tex]r=\sqrt{(-3-4)^2+(2-6)^{2}}\\\\=\sqrt{(-7)^{2}+(-4)^2}\\\\=\sqrt{49+16}\\\\= \sqrt{65}[/tex]
radius = √65
c) Equation of circle : (x - h)² +(y -k)² = r²
Where (h,k) is the coordinates of the center and r is the radius
(x -[-3])² + (y - 2)²= (√65)²
(x + 3)² + (y -2)² = 65

The circumference of a circle is 15.03
m. Find the radius and round to the
nearest hundredth.
Answer:
2.39 meters
Step-by-step explanation:
Given:
Circumference = 15.03 metersCircumference:
[tex]\displaystyle \large{C=2\pi r}[/tex]
C = circumference = 15.03r = radiusTherefore:
[tex]\displaystyle \large{15.03=2\pi r}[/tex]
Divide both sides by 2π:
[tex]\displaystyle \large{\dfrac{15.03}{2\pi}=\dfrac{2\pi r}{2\pi}}\\\displaystyle \large{2.3920... = r}[/tex]
Round to nearest hundredth:
[tex]\displaystyle \large{r=2.39}[/tex]
Therefore, the radius is 2.39 meters

Answer: B
Step-by-step explanation:
The solution is : B. f(x) does not have an inverse function, because its graph fails the horizontal line test.
What is graph?In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.
here, we have,
here, we have,
In the graph, we can see two asymptotes at x = 1.
This means that the denominator is equal to 0 when x = 1, then we can write:
f(x) = A/(x - 1)
Where we can start thinking that A is a constant.
Now we also can see that when x = 2, f(2) is equal to 1, or:
f(2) = 1.
Then:
f(2) = 1 = A/(2 - 1) = A/1
Then we have A = 1.
Then our function is:
f(x) = 1/(x - 1)
Hence, The solution is : B. f(x) does not have an inverse function, because its graph fails the horizontal line test.

Taylor starts a trip to the mall with $160 cash. After 20% of it is spent, seven-eighths of the remainder is lost to a pickpocket. This leaves Taylor with how much money?
Answer: $16
r=remainder
s=spent
r'=final remainder
160
160-(160 x .20) = r OR 160 x .80 = r
160-32 = r = 128 = 160 x .80 =
Then , 7/8 is lost so:
128 - (7/8 x 128) :
7/8=.875
128-(.875 x 128)
Using PEMDAS:
128-(112):
128-112= $16

Essentially, we want to find the number of ounces of dough she used to measure:
⇒ which means that we must convert the:
⇒ grams of dough to ounces of dough
⇒ 28.6 grams = 1 oz
Essentially,we can set up a proportion:
⇒ 28.6 grams to 1 oz
⇒ is to 200.2 grams to 'x' oz
(mathematically)
[tex]\frac{28.6}{200}=\frac{1}{x} \\28.6x = 2000\\x = 6.99[/tex]
Thus 200.2 grams is to 7 oz (rounded)
Answer: 7 ounces

1,030 at 4% compounded semiannually for 2 years
Answer: $1114.91
Step-by-step explanation:
The formula for compound interest is
[tex]A= P(1+\frac{r}{n})^{nt} \\[/tex]
Where
A = final amount
P = initial principal balance (1030 for this)
r = interest rate (0.04 for this)
n = number of times interest applied per time period (2 for this)
t = number of time periods elapsed (2 for this)
[tex]A= 1030(1+\frac{.04}{2})^{(2)(2)} \\\\A= 1030(1+0.02)^{4} \\A=1030(1.02)^4\\A=1114.905125[/tex]
This rounds up to $1114.91
A line passes through (-5,2) and has a slope of -1. What is an equation of the line in slope-intercept form?
A. y+2=-(x-5)
B. y=-x-3
C. y-2=-(x+5)
D. y=-x+3
Answer:
B. y=-x-3
Step-by-step explanation:
[tex]f(x) = ax + b \\ a = - 1 \\ (x \: y) = ( - 5 \: \: 2) \\ f( - 5) = - ( - 5) + b = 2 \\ 5 + b = 2 \\ b = - 3 \\[/tex]
So,
[tex]f(x) = - x - 3 \\ y = - x - 3[/tex]

Answer:
x = 3
Step-by-step explanation:
using the rule of exponents
[tex]4^{x}[/tex] = [tex](\frac{1}{2}) ^{x-9}[/tex]
[tex](2^2)^{x}[/tex] = [tex](2^{-1}) ^{x-9}[/tex]
[tex]2^{2x}[/tex] = [tex]2^{-1(x-9)}[/tex] = [tex]2^{9-x}[/tex]
suince the bases on both sides are equal, then equate the exponents
2x = 9 - x ( add x to both sides )
3x = 9 ( divide both sides by 3 )
x = 3

Suppose you take a sample of 15 pieces of colored fruit snacks and a sample of 60 pieces of colored fruit snacks from one day's production. Which sample is more likely to give you a prediction closer to the actual number of each color? Explain
Answer:
The sample of 15 pieces of colored fruit snacks
Step-by-step explanation:
The sample of 15 pieces of colored fruit snacks. The 60 pieces are from ONE day which means it can be heavily biased. It might be like "BLUE RASPBERRY SPECIAL DAY!" or "PRESIDENTS DAY!! RED BLUE AND WHITE!!". However, 15 pieces, whilst having less of a population, is probably more spaced out.

2) False
like therms aren't always polynomials.
3)False
it's doesn't always come out as diff. of two squares.
4)True
1x+3x =4x ( imagine 1 + 3 = 4 s) ( sum means "add up").
5)False
the O in FOIL means "outer" or "outside" (tip: FOIL means "First", "Outside", "Inside", "Last").
6) True
we can't add them together, they're "unlike terms".
7)True
"Z" is missing in the first term
8) False
they're were multiplied which means they become one term now.
9)Trueeee
having a negative symbol doesn't change nothing
10)False
it's will still take the power it came with which is "2"
