17.5 litres of must be added to 14 litres of a 90% acid solution to obtain a 40% acid solution.

A percentage is a number or ratio expressed as a fraction of 100.

Given that, there are 14 litres of a solution which is 90% acidic,

Let water added be x, then according to question,

0.90*14 = 0.40(x+14)

12.6 = 0.40x + 5.6

0.40x = 7

x = 17.5

The probability that they will run out of raw material is 0.78 or 78% if the order quantity is 150 gallons.

We have following information,

the demand for the polymer is distributed normally .

Mean (μ) = 250 gallons and Standard deviations (σ) = 125 gallons

Selling price of poymer = $25 per gallons

cost price of raw material for polymer= $ 10 per gallons

Salvage value = $(-5)/ gallon

Now, Using the formula for normally distributed sample,

Z = ( X - μ ) /σ

where , X---> sample mean

μ ----> population mean

σ----> standard deviations

Z -----> Z-value

from question it is clear X = 150

putting all the values of variables in above formula we get, Z = ( 150-250)/125 = -100/125

= - 0.8

(-0.8) value of z = 0.21 = 21% , the value of z is measure from normal distribution table.

They will run out of raw material if demands exceds this quantity or

Probability ( out of stock ) = 1 - 0.21 = 0.79 = 79%

Goop's purchases raw material for $10 per gallon and Goop mrust spend $5 per gallon to dispose off all unused raw material due to government regulations. (One gallon of raw material yields one gallon of polymer.) That is to say, the salvage value is $(-5)/gallon.

There will be 16 teaspoons of salt is needed for the 4 tablespoons of sugar.

Given, In a recipe, for every tablespoons of sugar there are four teaspoons of salt.

If a batch use four tablespoons of sugar then we have to find the number of tablespoons of salt needed.

as, 1 sugar = 4 salt

4 sugar = 4×4 salt

4 sugar = 16 salt

So, the number of tablespoons of salt needed is 16 for the use of 4 tablespoons of sugar.

Hence, there will be 16 teaspoons of salt is needed for the 4 tablespoons of sugar.

The required equation to determine the number of red sheets, r, required for each card is 8r + 20 = 30.

Let the required number of red paper be r. For one card, the 2.5 sheets of yellow paper are required. So, for 8 thank-you cards, the yellow papers required will be = 8×2.5

Number of yellow papers = 20

Total number of sheets required = Number of yellow sheets for 8 cards + Number of red sheets for 8 cards

Keep the values in formula to form the equation

30 = 20 + 8r

8r = 10

r = 10/8

r = 1.25

Answer:

y = 119

30 =x

Step-by-step explanation:

61 and y are same side interior angles and they add to 180

61+y = 180

y = 180-61

y = 119

y and 6x-61 are vertical angles and they are equal

y = 6x-61

119 = 6x-61

Add 61 to each side

119 + 61 = 6x

180 = 6x

Divide each side by 6

180/6 = x

30 =x

Answer:

y = 119°

x = 30°

Step-by-step explanation:

We know that if two lines are parallel, the co - interior angles are added up to 180°°.

Accordingly,

y + 61 = 180

y = 180 - 61

y = 119°

Also, we know that, vertically opposite angles are equal to each other.

y = 6x - 61

119 = 6x - 61

Now, we have to make x the subject.

For that, first, add 61 for both sides.

119 + 61 = 6x

180 = 6x

Now, divide both sides by 6.

30° = x

The equation of line parallel to the given line is found as y = -6x + 13.

The equation of the line is-

y = -6x + 1

The second line is parallel to the above line, thus the slopes of both the line are equal.

m1 = m2 = -6

The new line also passes from the point (1, 7)

(x1, y1) = (1,7)

Thus, the equation of the line will be calculated as-

y - y 1 = m2(x - x1)

y - 7 = -6(x - 1)

y - 7 = -6x + 6

y = -6x + 13

Thus, the equation of line parallel to the given line is found as y = -6x + 13.

We deduce that g(x) = f(x - 2) + 3 denotes a 2-unit right and 3-unit up in the graph of g(x). The best choice is C.

A diagram that shows how a variable varies in relation to one or more other variables, such as a collection of points, lines, line segments, curves, or regions.

Right-shift a function

Inside the function's argument, subtract. For instance, is essentially moved b units to the right.

You go to the right while subtracting from the parameter of the function.

Accordingly, f(x) is moved two units to the right in g(x) = f(x - 2).

also to advance a function

Outside of the function, add. For instance, is essentially shifted up units.

G(x) = f(x - 2) + 3 hence says that f(x) is shifted up by 3 units.

Overall, then, using two transformations, we deduce that g(x) = f(x - 2) + 3 denotes a 2-unit right and 3-unit upswing in the graph of g(x).

Therefore, choice C is right.

The probability that a person gets there in less than 3 minutes on at least 4 of the next 6 days is 0.3969.

A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities. By dividing the number of positive outcomes by the entire number of possible outcomes, probability—the likelihood that an event will occur—is determined. The most basic illustration is a coin toss. There are only two outcomes when you flip a coin: either it comes up heads or tails.

Given,

Mean = 4 minutes

= 1/4

= 0.25

The probability that someone will be attended to in less than three minutes on any given day is:

P( X ≤3)

= 1- e⁻⁰²⁵⁽³⁾

The probability is:

P( X ≥ 4)
