Therefore he took 40 gram of $1^(st)$ type solution and 10 gram of $2^(nd)$ type solution.

Step-by-step explanation:

Giventhat , A pharmacist 13% alcohol solution another 18% alcohol solution .

Let he took x gram solution of $1^(st)$ type solution

and he took (50-x) gram of $2^(nd)$ type solution.

Total amount of alcohol = $[x*(13)/(100)] +[(50 -x) *(18)/(100) ]$ gram

Total amount of solution = 50 gram

According to problem

⇔ $( [x*(13)/(100)] +[(50 -x) *(18)/(100) ])/(50)= (14)/(100)$

⇔ $(13x +900-18x)/(100*50) =(14)/(100)$

⇔- 5x= 700 - 900

⇔5x = 200

⇔x = 40 gram

Therefore he took 40 gram of $1^(st)$ type solution and (50 -40)gram = 10 gram of $2^(nd)$ type solution.

Jason ordered 239,021 pounds of flour to be used in 25 bakeries. The company delivering the flour showed up with 451,202 pounds. How many extra pounds of flour were delivered

Answers

Answer: 212181 pounds of flour were extra delivered.

Step-by-step explanation:

Since we have given that

Quantity of pounds of flour to be used in 25 bakeries ordered by Jason = 239021

Quantity of pounds of flour showed up =$451202

Extra pounds of flour were delivered is given by

$451,202-239,021=212,181\ pounds$

Hence, 212181 pounds of flour were extra delivered.

There were 212,181 extra pounds of flour delivered.

How to solve for the extra pounds of flour

To find out how many extra pounds of flour were delivered, you can subtract the quantity Jason ordered from the quantity delivered:

Extra pounds of flour = Quantity delivered - Quantity ordered

Extra pounds of flour = 451,202 pounds - 239,021 pounds

Extra pounds of flour = 212,181 pounds

So, there were 212,181 extra pounds of flour delivered.

Dave rented a limousine for his wife's birthday. The hourly rate is $60. They used the limousine for 5 hours, plus Dave gave the driver a 10% tip. How much did he spend in total for the hourly charges plus tip?

Answers

Given:
hourly rate $60
used for 5 hours
tip is 10%

Total rent= $60 * 5 hrs = $300
Total tip = $300 x 10% = $30
Total cost = $300 + 30 = $330

Dave spent a total of $330 for his wife's birthday.

$60*5 =
300*.10=
300+30=
330 divided by 5 is $66.00 an hour
66*5=$330

Kim and Courtney share a 16-ounce of box of cereal. By the end of the week, Kim has eaten 3/8 of the box, and Courtney has eaten 1/4 of the box of cereal. What fraction of the box is left?

Answers

³/₈

Further explanation

We will solve the problem of subtraction between fractions.

Given:

Kim and Courtney share a 16-ounce of the box of cereal.

By the end of the week:

Kim has eaten ³/₈ of the box, and
Courtney has eaten ¹/₄ of the box of cereal.

Question:

What fraction of the box is left?

The Process:

Kim has eaten ³/₈ of the box of cereal. Let's calculate how many fractions of the box are left after Kim has eaten them.

$\boxed{ \ 1 - (3)/(8) = \ ? \ }$

$\boxed{ \ (8)/(8) - (3)/(8) = (5)/(8) \ }$

Hence, the rest of the box after Kim has eaten ³/₈ of the box is

$\boxed{\boxed{ \ (5)/(8) \ }}$

Furthermore, Courtney has eaten ¹/₄ of the box of cereal. Let's calculate how many fractions of the box are left again after Courtney ate the remaining part since Kim had eaten it before.

$\boxed{ \ (5)/(8) - (1)/(4) = \ ? \ }$

Before we subtract, the denominator must be equated. Prepare ¹/₄ to be ²/₈. The numerator and denominator are multiplied by two.

$\boxed{ \ (5)/(8) - (2)/(8) = (3)/(8) \ }$

Thus, the fraction of the box left after Kim and Courtney have eaten is $\boxed{\boxed{ \ (3)/(8) \ }}.$ $\boxed{ \ The \ Answer \ }$

- - - - - - - - - -

Quick Steps:

$\boxed{ \ 1 - (3)/(8) - (1)/(4) = \ ? \ }$

$\boxed{ \ (8)/(8) - (3)/(8) - (2)/(8) = \boxed{ \ (3)/(8) \ } \ }$

The summary scheme is as follows:

Initial conditions

$\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot} \rightarrow \boxed{ \ one \ part = (8)/(8) \ }$

Kim has eaten ³/₈ of the box: $\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}$ $\rightarrow \boxed{ \ (3)/(8) \ }$

Courtney has eaten ¹/₄ (or ²/₈) of the box: $\boxed{\cdot}\boxed{\cdot}$ $\rightarrow \boxed{ \ (2)/(8) \ }$

Final conditions

$\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}$ is subtracted by $\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}$ and is subtracted by $\boxed{\cdot}\boxed{\cdot}$ equal $\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}$ as the remaining part $\rightarrow \boxed{\boxed{ \ (3)/(8) \ }}$

D.

infinitely many

Answers

This may be one of those questions that could take
more paper to ask than to answer.

Line-1 goes through (-4, 8) and (4,6) .

Its slope is (difference in 'y') / (difference in 'x')

Dif in 'y' = (6 - 8) = 2
Dif in 'x' = (4 - -4) = 8
Slope of Line-1 = 2/8 or 1/4

Line-2 goes through (-1, 1) and (3, 5)

Its slope is (difference in 'y') / (difference in 'x')

Dif in 'y' = (5 - 1) = 4
Dif in 'x' = (3 - -1) = 4
Slope of Line-2 = 4/4 = 1

Slope of Line-1 = 1/4
Slope of Line-2 = 4

The slopes of the lines are different.
They can't be parallel, and they can't be the same line.
They must intersect in one point, and only one point.

That means the pair of equations has exactly one (1) solution.
