Answer:
The difference in the amounts of carbon powder and ammonium carbonate is [tex]88.3\times 10^{-6}[/tex] grams.
Step-by-step explanation:
According to this statement, we have a mixture with [tex]3.7\times 10^{-6}[/tex] grams of carbon powder and [tex]92\times 10^{-6}[/tex] grams of ammonium carbonate. The difference between those amounts consist in subtracting the latter quantity for the former one. That is:
[tex]\Delta m = 92\times 10^{-6}\,g \,-\,3.7\times 10^{-6}\,g[/tex]
[tex]\Delta m = 88.3\times 10^{-6}\,g[/tex]
The difference in the amounts of carbon powder and ammonium carbonate is [tex]88.3\times 10^{-6}[/tex] grams.

The scatter plot shows the average movie ticket prices since 1995.
write an equation in slope intercept form for the line that is drawn
use your equation to make a conjecture about the average cost of a movie ticket in 2020
Answer:
The average movie ticket prices in 2020 was $ 10.25.
Step-by-step explanation:
If (0 , 4) and ( 8, 6) are two points on a line, the slope of the line is:
m= y2 - y1/ x2 - x1
m= (6 - 4) / (8 - 0)
m= 1 / 4
The y-intercept is $ 4, meaning it is the average movie ticket price in 1995.
Therefore,
Y = mx + b
Y = 1/4 x + b
It is m= 1/4, interpreting the slope we have that for every additional 4 years the average movie ticket price will increase by $ 1.
The year 2020 is 25 years after 1995, then
Y= 1/4 (25) + 4
Y = $ 10.25
The average movie ticket price was $10.25 in 2020.

A cylindrical candle has a volume of approximately 400cm^3 and is 8 cm tall. What is the radius of the candle?
Answer:
Solution :-We know that
V = πr²h
400 = 22/7 × r² × 8
400 × 7 = 22 × 7r²
2800 = 154r²
2800/154 = r²
18 ≈ r²
4.2 = r
Michelle and Natasha each had to repair their new iPhones. The initial cost of each repair is $ 100. Michelle and Natasha each have two discount coupons. Each of them uses both coupons toward the cost of the repair. One coupon is for $25 off the repair cost and the other coupon is for 20% off the repair cost. Michelle and Natasha use their coupons in a different order, as shown below. Michelle uses the 20% off the repair cost coupon first. She then uses the $25 off the repair cost coupon on the remaining balance. Natasha uses the $25 off the repair cost coupon first. She then uses the %20% off the repair cost coupon on the remaining balance.

Step-by-step explanation:
Which of the following statements represents a correct relationship?
a.) 345 > 354
b.) 400 < 40
c.) 4,008 < 4,080
d.) 23,090 = 23,009
Answer:
I think C
so it's kind of a process of elimination you have to see the order of the numbers and what order each number is in so for A you can see that it's 345 is greater than 354 which is inspect cuz 354 is greater than 345 for B that's an obvious answer is is 400 is less than 40 which is obviously wrong because 400 is greater has two zeros and 40 only has one 0 for C it has 4008 is less than 4080which is actually correct if you look at the way that the numbers are written you could see that 80 is greater than 8 D it's obviously not correct because it says 20090 is equal to 23009 which is incorrect because 90 is greater than 9

5+2x = -27/8
How explain
Answer:
x = -4 3/16.
Step-by-step explanation:
First, convert -27/8 to a mixed number. -3 3/8.
So we can take 5 + 2x = -3 3/8 and subtract 5 from both sides (to get rid of the 5 on the left)
The equation turns into this: 2x = -8 3/8.
Now we can divide by 2 on both sides.
The equation becomes x = -4 3/16.

A teacher wants to choose a student at random. The teacher decides to choose the first person to walk through the classroom door at the start of the lesson.
a. Explain why this is not a good method.
2. Suggest a better method.
Answer:
The first person to arrive is not random. The person that mostly arrives first every time is the person who lives closest to the school, or is a teacher's pet.
The odds of the person who lives 20km away from the school being first are way lower than anyone else.
A better method, would be everyone writes their name on a paper, and the teacher picks one at random from a hat.

What is the slope of the line that passes through the points (-6,8) and (-16,33)
Answer:
-5/2 or -2.5
Step-by-step explanation:
Find the slope using rise over run (y2 - y1) / (x2 - x1)
(y2 - y1) / (x2 - x1)
(33 - 8) / (-16 + 6)
25 / -10
= -5/2
So, the slope is -5/2 or -2.5
Answer:
Solution :-We know that
Slope
[tex] \bf \: \dfrac{y_2 - y_1}{x_2 - x_1} [/tex]
Where
y2 = 33
y1 = 8
x2 = -16
x1 = -6
33 - 8/-16 - 8
25/-24
Sodas cost $1.50 and a cup of coffee costs $1.25 at a football game. Sally
bought 8 drinks total for all of her friends and her total cost was $11.50. How
many of each drink did she buy?
Answer:
the answer 4
Step-by-step explanation:
4 of each because (1.25x4) + (1.50x4) = 11.50
Answer:
Sally bought 6 sodas and 2 cups of coffee.
Step-by-step explanation:
Variable x = number of sodas
Variable y = number of coffees
$1.50x + $1.25y = $11.50
x + y = 8 drinks
$1.50(6) + $1.25(2) = $11.50
$9.00 + $2.50 = $11.50
I simply plugged in numbers that totalled to 8 drinks until I reached $11.50 as the total.
For example:
$1.50(5) + $1.25(3) = $11.50
$7.50 + $3.75 = $11.50
$11.25 = $11.50
This is not correct as they do not equal so this cannot be the answer.

∠A and ∠B form linear pair. If m∠A =(6x-19)° and m∠B=(11x-22)°, find m∠B.
Answer: 121°
Step-by-step explanation:
The measure of angle B will be [tex]121^0[/tex] .
What is angle?Angle is formed by two rays lie in the plane that contains the rays.
We have,
[tex]m \angle A =(6x-19)^0[/tex]
Now,
Linear pair angles are those angles whose sum is [tex]180^0[/tex] .
i.e.
[tex]m \angle A + m \angle B=180^0[/tex]
So,
[tex](6x-19)^0 +(11x-22)^0 =180^0[/tex]
Now,
[tex]17x-41=180[/tex]
[tex]17x=221[/tex]
[tex]x=13[/tex]
So,
[tex]m\angle B=(11x-22)^0[/tex]
Putting value of x;
[tex]m\angle B=(11*13-22)^0[/tex]
[tex]m\angle B=(121)^0[/tex]
So, measure of angle B is [tex]121^0[/tex].
Hence, we can say that the measure of angle B will be [tex]121^0[/tex] .

Answer:
B, C, D
Step-by-step explanation:
7x + 1 + 105 = 180
7x = 74
x = 74/7
4y + 14 + 7y + 1 = 180
11y = 165
y = 15
m<A = 4y + 14 = 4(15) + 14 = 74°

Answer:
tan ∅ = 16/12
Step-by-step explanation:
Once again here are the trigonometric ratios
Sin = Opposite over Hypotenuse
Cos = Adjacent over Hypotenuse
Tan = Opposite over Tangent
We are asked to find tan ∅
Looking at the trigonometric ratios we see that tan = opposite over adjacent
So we find the side length opposite of the indicated angle (∅) which would be 16 then we find the angle adjacent angle ( the side that is not the hypotenuse nor the opposite ) so the adjacent of angle ∅ is 12
so tan ∅ = opposite (16) over adjacent (12)
tan ∅ = 16/12
