how much water must be added to a 9-liter solution that contains 3% extract on baneberry to get a solution that contains 2% extract of baneberry
Answer:
Amount water added = 4.5 L
Step-by-step explanation:
Given:
Amount of solution = 9 L
Amount of bane-berry = 3% of 9 L = 0.27 L
Computation:
Assume;
Amount water added = x L
Total solution = 9+x L
New percentage of bane-berry = 0.27x100/(9+x)
2 = 0.27*100/(9+x)
x = 4.5 L
Amount water added = 4.5 L

Explanation:
y = x - 4
y = 6x - 10
-----------------------
x - 4 = 6x - 10
-4 = 6x - x - 10
10 - 4 = 5x
x = 1.2
-----------------------
y = x - 4
y = 1.2 - 4
y = -2.8

Answer:
Step-by-step explanation:
x + 5y = -23
5x - 5y = 5
6x = -18
x = -3
-3 + 5y = -23

Express each ratio as a fraction in simplest form 16 feet out of 40 feet
Answer:
Step-by-step explanation:
Start by dividing top and bottom by 4
16 / 4 = 4
40/4 = 10
The result so far is 4/10
But 4/10 is not the answer. You can divide 4 and 10 by 2
4/2 = 2
10/2 = 5

What is Unitary method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary MethodFirst, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
cost of gas with tax is $3.81 per gallon
But gas should be less than 14 gallons and not more than 8 gallons.
So,
=3.81×8
=30.48
3.81×14
=53.34
Hence, the range is 30.48 to 53.34,

Anna also wants to travel after graduation but she isn’t working while in school so she won’t be able to put money aside regularly. However, her grandmother gave her the generous gift of $2500 for her birthday and suggested she invest it in a GIC because it’s low risk. She shopped around and found a 4 year GIC investment that earns 2.8% interest annually. How much will Anna have at the end of her four year investment?
Answer:
She will have $2792 at the end of her four year investment
Step-by-step explanation:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Gift of $2500:
This means that [tex]P = 2500[/tex]
She shopped around and found a 4 year GIC investment that earns 2.8% interest annually.
This means that [tex]t = 4, r = 0.028, n = 1[/tex].
How much will Anna have at the end of her four year investment?
This is A(4). So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(4) = 2500(1 + 0.028)^{4} = 2792[/tex]
She will have $2792 at the end of her four year investment

Answer:
x ≤ 2
Step-by-step explanation:
Maybe you're trying to solve ...
5x - 18 ≤ -8
As with any 2-step equation, add the opposite of the constant that is on the same sides as the variable term.
5x -18 +18 ≤ -8 +18
5x ≤ 10 . . . . . . . . . . . simplify
Now, divide both sides by the coefficient of the variable.
5x/5 ≤ 10/5
x ≤ 2 . . . . . . . . . . . . . simplify
