Step-by-step explanation:
1) Molecular weight = vapour density × 2 = 43 = 86
→ Empirical formula × n
→ n = molecular weight/vapour density = 86/43 = 2

Solve the exponential equation: 4 1/2x=256
A) x = 4
B) x = 2
C) x= 8
OD) x= 1/2
Hi there!
We are given:
[tex]4^{\frac{1}{2}x} = 256[/tex]
We can rearrange this into a logarithm:
[tex]log_4256 = \frac{1}{2}x[/tex]
Evaluate the left side:
4 = 1/2x
Multiply both sides by 2:
x = 8

Step-by-step explanation:
this mathematics is very by explanations ,
Firstly, look for the LCM of the in the denominators ,that is look for the LCM of 3,15,5 which is 15 then a straight line keep the denominators result from the LCM under the straight line then use the denominators to divide 15 and multiply with numerators and then add the results and then you divide it by 15 and the result is 17 then 17/15 then you have one whole number,two over fifteen

You know that the gas tank in your car holds 20 gallons of gas and the gauge reads 1/4 full. The price of gasoline is $3.10 per gallon. How much will it cost to fill up the car?
Answer:
$46.50
Step-by-step explanation:
20/4 =5
1/4 is already full so u only need 15 gallons
15 × $3.10 = $46.50

You know that the gas tank in your car holds 20 gallons of gas and the gauge reads 1/4 full. The price of gasoline is $3.10 per gallon. How much will it cost to fill up the car?[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Gallons the car can hold = 20Fraction of gallons that are present in the car = 1/4Fraction of gallons left to fill = 3/4 [4/4 - 1/4 = 3/4]Gallons left to fill = 15 [20 × 3/4 = 15]Cost per gallon of gasoline = $ 3.10Cost to fill up the car = ?Now, let's solve it.
First we've to form an equation ... we know from the statements given above (in bulletin points) that ⇨ 3.10 × 15 = cost to fill up the car.
Let's use it to solve the question.
[tex] \sf3.10 \times 15 \\ = \boxed{ \boxed{\bf 46.5 \: dollars}}[/tex]

given PR with P(-6, -6) and R(-2, 10), if Q lies on PR such that the ratio of PQ to PR is 5:8 find the coordinates of Q
Lines can be divided into segments using ratios. The coordinates of Q when PR is divided into 5:8 is [tex](-4.462,0.154)[/tex]
Given that:
[tex]P (x_1,y_1) = (-6,-6)[/tex]
[tex]R (x_2,y_2) = (-2,10)[/tex]
[tex]m:n = 5:8[/tex] --- the ratio
The coordinate of Q is calculated using the following line ratio formula
[tex]Q = \frac{1}{m+n}(mx_2 + nx_1,my_2 + ny_1)[/tex]
So, we have:
[tex]Q = \frac{1}{5+8}(5\times -2 + 8\times -6,5\times 10 + 8\times -6)[/tex]
[tex]Q = \frac{1}{5+8}(-58,2)[/tex]
[tex]Q = (-58/13,2/13)[/tex]
[tex]Q = (-4.462,0.154)[/tex]
Hence, the coordinates of Q is [tex](-4.462,0.154)[/tex]

a store is selling a sweater for $68. if the state adds in a 8.5% sales tax, find the total price of the sweater
Answer:
$73.78
Step-by-step explanation:
$68 + (68*8.5%)
$68 + (68*0.085)
$68 + $5.78
$73.78
The total price of the sweater will be $73.78.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
The percentage is just like the amount of that value but in between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.
Given that,
Price of sweater = $68
Percentage tax on the price of sweater = 8.5%
Now,
8.5% of 68 will be
⇒ 8.5 × 68/100 = $5.78
So, the total price will be
⇒ 68 + 5.78 = $73.78
Hence "The total price of the sweater will be $73.78".

Help with fraction. It’s been awhile and I forgot what to do with this process …
Step-by-step explanation:
[tex] \frac{ \frac{1}{5} - \frac{1}{2} }{5 - 2} [/tex]
[tex] \frac{ \frac{2}{10} - \frac{5}{10} }{3} = \frac{ \frac{2 - 5}{10} }{3} = \frac{2 - 5}{10 \times 3} [/tex]
[tex] \frac{ - 3}{30} = \frac{ - 1}{10} [/tex]
Answer:
Do the subtractions in the numerator and denominator.
1/5 - 1/2 = 2/10 -5/10 = -3/10
5 -2 = 3
that equals -3/10 / 3 which equals -.1
OR multiply top and bottom by 10 which equals
-3 / 30 which also equals -.1
