Using the concept of volume, 700 milliliters of Solution B was used.
What is volume?Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
When dealing with unknowns, the first step is to represent the unknowns using variables, draw up equations based on the available data, and then solve those equations to account for the unknowns.
Volumes of solutions A and B are here which is unknown.
Put these factors in place for us
Let x = the amount of solution A that was mixed in milliliters.
Let y= the amount of solution B that was mixed in milliliters.
The amount of volume utilized for A is 400 ml less than the amount used
for B.
This can be expressed mathematically as y - x = 400.
Or,
- x + y = 400 [1]
The ratios of alcohol in A and B are provided to us.
A contains 12% alcohol, hence its real alcohol content is 12% of x ml.
= 0.12x (12% = 12/100 = 0.12)
Similar to A, B has an alcohol content of 0.20x.
If x of A and y of B are combined, the total alcohol by volume is 0.12x + 0.20y.
and it is said that this amount is 176 ml.
Our second equation is therefore set up as 0.12x + 0.20y = 176 [2].
We create an equation containing only the other term by using both equations and removing either the x or y terms.
We should remove the x term from both equations to create a single equation that just contains the y term because the question only asks us to compute the volume of Solution B that was used.
Review the equations now:
- x + y = 400 [1]
0.12x + 0.20y = 176 [2]
x's coefficients should all be the same:
Increase [1] by 0.12
=> -0.12x + 0.12y =
= 0.12 x 400
=> 0.12x + 0.12y = 48 [3]
By adding [2] and [3], the x word is removed.
0.12x + 0.20y = 176+( -0.12x) + 0.12y = 48
0x + 0.32 y = 224
=> 0,32y = 224
Subtract 0.32 from both sides to get[tex]\frac{0.32y}{0.32}[/tex] = [tex]\frac{224}{0.32}[/tex]
==> y = 700
Therefore, 700 cc of Solution B was utilized.

The company with the common equity accounts shown here has declared a stock dividend of 20 percent at a time when the market value of its stock is $30 per share. Common stock ($1 par value) $ 460,000 Capital surplus 861,000 Retained earnings 3,870,800 Total owners' equity $ 5,191,800 What would be the number of shares outstanding, after the distribution of the stock dividend? (Do not round intermediate calculations.)
1110800. Equity Account will be after stock dividends
What is stock dividend ?Similar to a cash dividend, however instead of cash, stocks are given out. A stock dividend will increase the number of shares outstanding while lowering the stock price.
In this issue, there are 460000 shares outstanding at a price of $30, which equals 13800000
Equity's total market value is $13800000.
Each shareholder will get a 20% increase in stock, and the number of existing shares will increase as a result of the 20% stock dividend.
Shares outstanding after dividend announcement total 460000 + 46000 ×20% =552000.
The number of outstanding common shares will rise to 552000 as a result of the issuance of 92000 more shares.
Common stock only contains the par value; for example, if the market price of a share is $30 and the par value is $1, the excess amount of $29×92000:2668000 is added to the capital surplus account. It will total 861000 + 2668000=3529000.
Due to the absence of any monetary transactions, the total owners' equity is unaltered.
The retained earnings will be decreased by 92000 × 30 = 2760000, resulting in 3870800 – 2760000=1110800.
Equity Account will be after stock dividends.

[tex]a=-4[/tex]the cost of 12 hot dogs and 8 fry portions is £52. The cost of 8 hot dogs and 12 fry portions is £48. What is the total cost of a hot dog and a portion of fries?
Answer:
Hot dogs cost £3 and fry's cost £2.
Total cost £5.
Step-by-step explanation:
Let a hot dog cost £x and a portion of fry's cost £y.
Then:
12x + 8y = 52
8x + 12y = 48
Simplifying these 2 equations we get:
3x + 2y = 13 ---------- (A)
2x + 3y = 12...............(B)
multiply the first equation by 2 and the second by 3:
6x + 4y = 26
6x + 9y = 36
Subtracting:
0 - 5y = -10
y = -10/-5 = 2.
Now, substituting in equation (A):
3x + 2(2) = 13
3x = 9
x = 3.

a woman can hike 2mph faster down a trail to Archuletta Lake then she can on the return trip uphill. it takes her 2 hours to get to the lake and 4 hours to return. what is her speed hacking down to the late?
Answer:
4 mph
Explanation :
Let us call x, the woman speed as she goes uphill
Now, we know that it took the woman 2 hours to go uphill; therefore, the distance covered is
4* (x)
shortly afterwards, when the woman returns she is walking at x + 2 mph; therefore, the distance she covers is
D = 4 (x +2 )
Since the uphill and the downhill distances ar the same, we have
4x = 2 (x +2 )
4x = 2x + 4
x = 2
Hence, going to the hill, the woman speed is 2 miles per goo
angela spends $95 to buy 7 cakes for the office party. she cuts each cake into quarters, then cuts each quarter into 3 pieces. if kevin eats 5 pieces of cake during the party, how much did engela spend on just kevins share of the cake
If Angela spent $95 to buy 7 cakes for her office party, and she then cut each cake into quarters and each quarter into further 3 pieces, of which Kevin ate 5 pieces, then Angela had spent $5.65 on just the share of the cake that Kevin had.
As per the question statement, Angela spends $95 to buy 7 cakes for her office party, and she then cuts each cake into quarters and each quarter into further 3 pieces, of which Kevin ate 5 pieces.
We are required to calculate the amount Angela had spent on just the share of the cake that Kevin had.
To solve this question, first let us calculate the total number of pieces, did Angela cut all the 7 pieces of the cake into.
Considering one piece, that it was first cut into a quarter and then each quarter into further 3 pieces, one single piece out of original 7 pieces was cut into a total of [(4 * 3) = 12] pieces.
Therefore, all the 7 original pieces were altogether cut into a total of
[(7 * 12) = 84] pieces.
Now, since Angela spent $95 to buy the original 7 pieces,
Or, Angela actually spent $95 to buy 84 pieces of cake,
Then, 1 piece of the 84 costs $(95/84) = $1.13.
Now, since Kevin ate 5 such pieces of the 84, those 5 pieces cost
$(1.13 * 5) = $5.65.
Therefore, Angela had spent $5.65 on just the share of the cake that Kevin had.

g(x) = x2 − 5x
h(x)= 4x + 4
Find (g ◦ h) (x)
Answer:
(g ◦ h) (x) = 16x² + 12x -4
Step-by-step explanation:
We have
g(x) = x² − 5x
h(x)= 4x + 4
(g ◦ h) (x) = g(h(x))
h(x) = 4x + 4
g(h(x)) = g(4x + 4)
= (4x + 4)² - 5(4x+4) //substitute 4x + 4 wherever there is an s-term in
(4x + 4)² = 16x² + 32x + 16
5(4x + 4) = 20x + 20
(4x + 4)² - 5(4x+4) = 16x² + 32x + 16 -(20x + 20)
= 16x² + 32x + 16 - 20x - 20
= 16x² +(32x - 20x) + (16-20)
= 16x² + 12x -4

What is a compound interest?Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit. It occurs when interest is reinvested, or added to the loaned capital rather than paid out, or when the borrower is required to pay it so that interest is earned the following period on the principal amount plus any accumulated interest. In finance and economics, compound interest is common.So, the principal amount is $640 and the obtained amount is $760.
Compounded annually for 5 years.Then the interest rate will be:
