The amount and the concentration of a salt solution.
Answer:
28 g
3.4 g
Explanation:
These problems only make sense if the percentage is by weight. To find the amount of salt, multiply the amount of solution by the percentage that is salt:
a) (80 g)(35%) = 28 g . . . . weight of salt
__
b) (20 g)(17%) = 3.4 g . . . . weight of salt
_____
Comment on percent
You know that % means /100, so 35% = 35/100 = 0.35.

The fifth term of a geometric sequence is 781. 25. Each term of the sequence is of the value of the following term. Which recursive formula represents the situation?.
Answer: an = 5an-1
Explanation: Given fifth term of a geometric sequence is 781.25.
a5 = 781
Also, each previous term is 1/5 of the value of the current term.
Therefore, common ratio would be 5.
But we just need to find the recursive formula .
Recursive formula of a geometric sequence is given by
Plugging value of r in above formula, we get
Therefore, recursive formula would be represents the situation.
The recursive formula that represents the situation is: [tex]t_n = a^{(3/4)} * 781.25^{(1/4)} * n^{(1/4)}[/tex].
What is recursive formula?A recursive formula is one that defines any term in a sequence in terms of the term(s) before it.
Let the first term of the geometric sequence be 'a' and the common ratio be 'r'.
We are given that the fifth term is 781.25, so we can write:
a * [tex]r^4[/tex] = 781.25
We also know that each term is the value of the following term, so we can write the recursive formula:
t_n = r * t_(n-1)
Where t_n is the nth term of the sequence and t_(n-1) is the previous term.
To express the recursive formula in terms of 'a' and 'r', we can use the formula for the nth term of a geometric sequence:
[tex]t_n = a * r^{(n-1)[/tex]
Substituting the recursive formula, we get:
[tex]r * t_{(n-1)} = a * r^{(n-1)[/tex]
Dividing both sides by r^(n-1), we get:
[tex]t_{(n-1)} = a * r^{(n-2)[/tex]
So the recursive formula in terms of 'a' and 'r' is:
t_n = r * t_(n-1)
[tex]= r * (a * r^{(n-2)})\\\\= a * r^{(n-1)[/tex]
Now we can substitute the value of the fifth term (781.25) to solve for 'a' and 'r':
a * [tex]r^4[/tex] = 781.25
Dividing both sides by a, we get:
[tex]r^4[/tex]= 781.25/a
Taking the fourth root of both sides, we get:
r = [tex](781.25/a)^{(1/4)[/tex]
Substituting this value of 'r' into the recursive formula, we get:
[tex]t_n = a * ((781.25/a)^{(1/4)}){^(n-1)}\\\\= a^{(3/4)} * 781.25^{(1/4)} * n^{(1/4)}[/tex]
Therefore, the recursive formula that represents the situation is:
t_n = a^(3/4) * 781.25^(1/4) * n^(1/4)

I am thinking of two positive numbers in the ratio $5:3$. The difference between the two numbers is $90$. What is the sum of the two numbers?.
The sum of the two numbers is $ 360
Let the bigger number be x
Let the smaller number be y
From the question given above, we were told that two numbers exist in ratio $ 5 : $ 3
Thus,
x : y = 5 : 3
x/y = 5/3
Cross multiply
x = 5y/3 ............ (1)
Also, we were told from the question that difference between the two numbers is $ 90 i.e
x – y = 90 ........... (2)
Substitute the value of x in equation (1) into equation (2). We have:
x = 5y/3 ............ (1)
x – y = 90 ........... (2)
5y/3 – y = 90
Multiply through by 3
5y – 3y = 270
2y = 270
Divide both side by 2
y = 270 / 2
y = $ 135
Substitute the value of y into equation 1 to obtain the value of x.
x = 5y/3 ............ (1)
y = $ 135
x = (5 × 135)/3
x = 675 / 3
x = $ 225
Finally, we shall determine the sum of the two numbers.
x = $ 225y = $ 135Sum =?Sum = x + y

How much heat must be removed from 456 g of water at 25.
The chemical equation below shows the combustion of methane (ch4). Ch4 + 2o2 right arrow. Co2 + 2h2o the molar mass of oxygen gas (o2) is 32. 00 g/mol. The molar mass of carbon dioxide (co2) is 44. 01 g/mol. What mass of co2, in grams, will form when 8. 94 g o2 completely react?.
Taking into account the reaction stoichiometry, 6.15 grams of CO₂ are formed when 8.94 grams of O₂ reacts completely.
In first place, the balanced reaction is:
CH₄ + 2 O₂ → CO₂ + 2 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
CH₄: 1 mole O₂: 2 moles CO₂: 1 mole H₂O: 2 molesThe molar mass of the compounds is:
CH₄: 16.04 g/mole O₂: 32 g/moleCO₂: 44.01 g/moleH₂O: 18 g/mole
Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
CH₄: 1 mole× 16.04 g/mole= 16.04 gramsO₂: 2 moles× 32 g/mole= 64 gramsCO₂: 1 mole× 44.01 g/mole= 44.01 gramsH₂O: 2 moles× 18 g/mole= 36 grams
Then the following rule of three can be applied: if by reaction stoichiometry 64 grams of O₂ form 44.01 grams of CO₂, 8.94 grams of O₂ form how much mass of CO₂?
[tex]mass of CO_{2} =\frac{8.94 grams of O_{2} x44.01 grams of CO_{2} }{64 grams of O_{2}}[/tex]
mass of CO₂= 6.15 grams
Finally, 6.15 grams of CO₂ are formed when 8.94 grams of O₂ reacts completely.

An 85-foot wire is tied from the top of a utility pole to the top of the building as shown below. Find d, the distance from the pole to the building.
The distance from the pole to the building is 79 feet
The relationship between the utility pole and the 85-foot wire, can be adjusted to fit in the description of a right-angled triangle.
So, the distance (d) can be calculated using the following sine function.
[tex]\sin(68) = \frac{d}{85}[/tex]
Multiply both sides of the equation by 85
[tex]85 \times \sin(68) = \frac{d}{85} \times 85[/tex]
Cancel out the common factors
[tex]85 \times \sin(68) = d[/tex]
Evaluate sin(68)
[tex]85 \times 0.9272 = d[/tex]
Evaluate the product
[tex]78.812 = d[/tex]
Approximate
[tex]79= d[/tex]
