P = Aekt

Answers

Answer 1

Answer:

1350

Step-by-step explanation:

1000 to 1100 is an increase of 100 bacteria per 6 hours

100/6 = 16.67 bacteria per hour

16.67 * 15 hours = 250

Total bacteria should be 1100+250= 1350

hope this helps :D

Answer 2

Answer:

1,500 bacteria.

Step-by-step explanation:

I don't know what P=Aekt means but I understand the rest:

Hour 0: 1,000 bacteria

Hour 6: 1,300 bacteria

We can conclude from this evidence that it takes 6 hours to grow 300 new bacteria.

Let's use a ratio

new bacteria : hours

      300          :     6

        50          :      1

       500         :     10

So we get 500 new bacteria after 10 hours. Using our original population of 1,000 and our new added members, we get 1,500 bacteria at Hour 10.

twice a number decreased by 20 is 50.

Answers

Answer:

The number is 35.

Step-by-step explanation:

Let the number be x

Twice the number: 2*x = 2x

Twice the number decreased by 20: 2x - 20

2x - 20 = 50

Add 20 to both sides

2x - 20 +20 = 50 + 20

2x = 70

Divide both sides by 2

2x/2 = 70/2

x = 35

Answer:

Step-by-step explanation:

[tex]\[ \csc(\theta) = \frac{15}{12} = \frac{5}{4} \][/tex] Option C. 15/12 is the Right Choice.

In a right triangle, the cosecant ([tex]\(\csc\)[/tex]) of an angle is the ratio of the length of the hypotenuse to the length of the side opposite the angle. In this scenario, we're given an angle [tex]\( \theta \)[/tex] and the side opposite to it measures 12 units. The length of the hypotenuse is denoted as [tex]\( r \)[/tex], and the length of the other side is 9 units.

To find the length of the hypotenuse ([tex]\( r \)[/tex]), we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. So, we have:

[tex]\[ r^2 = 12^2 + 9^2 \][/tex]

[tex]\[ r^2 = 144 + 81 \][/tex]

[tex]\[ r^2 = 225 \][/tex]

Taking the square root of both sides, we get [tex]\( r = 15 \)[/tex].

Now that we have the length of the hypotenuse ([tex]\( r = 15 \)[/tex]), we can find the cosecant ([tex]\(\csc\)[/tex]) of angle [tex]\( \theta \)[/tex]. The definition of [tex]\(\csc\)[/tex] in a right triangle is:

[tex]\[ \csc(\theta) = \frac{r}{\text{opposite side}} \][/tex]

Substituting the values we have, we get:

[tex]\[ \csc(\theta) = \frac{15}{12} \][/tex]

Simplifying this expression, we find that:

[tex]\[ \csc(\theta) = \frac{5}{4} \][/tex]

Therefore, the value of [tex]\( \csc(\theta) \)[/tex] is [tex]\( \frac{5}{4} \)[/tex]. Hence, the correct answer is C. 15/12.

5 less than 18 times the number x, is less than of equal to -45. write and inequality for this statement

Answers

Answer:

18x-5≤-45

Step-by-step explanation:

Final answer:

The statement '5 less than 18 times the number x is less than or equal to -45' translates to the inequality '18x - 5 ≤ -45'. This can be solved to yield 'x ≤ -20/9'.

Explanation:

The phrase '5 less than 18 times the number x' can be written as an expression '18x - 5'. The complete inequality saying this is less than or equal to -45 can thus be written as '18x - 5 ≤ -45'.

To clarify, this means that if you were to multiply a number 'x' by 18, and then subtract 5, the resulting number should be less than or equal to -45.

This is a type of linear inequality and can be solved in a similar way to a linear equation. Subtracting 5 from both sides yields '18x ≤ -40', and then dividing by 18 gives the solution 'x ≤ -40/18' or 'x ≤ -20/9' in simplified form.

O
There are probably more blue marbles than red marbles in the bag.

Answers

Answer:

(D) There are probably more blue marbles than red marbles in the bag.

Step-by-step explanation:

There are a total of 100 marbles in the bag.

In the experiment of 50 trials, Sam had the following outcome:

Blue=35

Red=15

Relative Frequency of Blue Marbles =35/50=0.7

Relative Frequency of Red Marbles =15/50=0.3

Since the relative frequency of blue marbles is greater than the relative frequency of red marbles, there are probably more blue marbles than red marbles in the bag.

If a car can drive 62 miles on 3 gallons of gas, how many gallons of gas will it use to travel 231 miles?

Answers

Answer:

x =11.17741935 gallons

Step-by-step explanation:

We can use a ratio to solve

62 miles    231 miles

---------     = -----------

3 gallons      x gallons

Using cross products

62x = 231 *3

62x =693

Divide each side by 62

62x/62 = 693/62

x =11.17741935 gallons

Answer: 11.1774194 gallons of gas

Explanation: To solve this problem, our first step is to write down the unit ratio that is involved. In this case, it's miles traveled/gallons of gas.

Next, we set up a proportion based

on the information in the problem.

We know that a car gets 62 miles for every 3 gallons so we have 62/3 and we're asked how many gallons of gas

will it use to travel 231 miles so that's 231/x.

Notice that the 231 miles must go on top in the second ratio

because our unit ratio tells us that we put miles over gallons.

Solving from here, we use the means-extremes property which states that the product of the extremes, (62)(x) equals the product of the means, (3)(231).

So we have the equation 62x = 693.

Now, dividing both sides of the equation

by 63, we find that x = 11.1774194.

This means that the car will use 11.1774194

gallons of gas to travel 231 miles.

If ABCD is a rhombus AD=4x+2 DC=7x-13 and BD=34 find AE (E is in the middle)

Answers

Answer: Line AE equals 14 units (approximately)

Step-by-step explanation: If you have a rhombus given, it is important to begin by highlighting the properties of a rhombus. A rhombus first of all is four-sided shape with all sides congruent, then the two opposite sides are parallel and congruent. Also, the diagonals bisect each other into two equal halves each.

Therefore, we shall examine a rhombus labelled ABCD, with side AD measuring 4x + 2, and side DC measuring 7x - 13. Then BD is a diagonal from point B to point D, and it measures 34 units. Also a diagonal is drawn halfway from point A and stops at point E (E is in the middle), where it bisects diagonal BD into two halves. Remembering that all sides of a rhombus are equal, then note that AD equals DC, that is;

4x + 2 = 7x - 13

2 + 13 = 7x - 4x

15 = 3x

Divide both sides of the equation by 3

5 = x

If AD = 4x + 2, then when x  = 5

AD = 4(5) + 2

AD = 20 + 2

AD = 22

Therefore triangle ADE can now be isolated with side AD measuring 22 units and side ED measuring 17 units (midpoint between points B and D). Line AE can be calculated using the Pythagoras theorem which states as follows;

AC² = AB² + BC²

Where AC is the hypotenuse, and AB and BC are the two other sides

Substituting for values as given in the question, we now have;

AD² = ED² + AE²

22² = 17² + AE²

484 = 289 + AE²

484 - 289 = AE²

195 = AE²

Add the square root sign to both sides of the equation

√195 = √AE²

13.96 = AE

Therefore line AE ≈ 14 units (to the nearest whole number)

a. x = 6, y = 9, z = –6
b. x = 1, y = 3, z = 4
c. infinite solutions
d. no solution

Answers

Answer:

no solution

Step-by-step explanation:

–5x – 12y – 43z = –136

–4x – 14y – 52z = –146

21x + 72y + 267z = 756

Every coefficient of the second equation is a multiple of 2, so divide both sides by 2.

Every coefficient of the third equation is a multiple of 3, so divide both sides by 3.

–5x – 12y – 43z = –136

–2x – 7y – 26z = –73

 7x + 24y + 89z = 252

Let's call the above system the "simplified original system."

Using the simplified original system, multiply the first equation by -2 and the second equation by 5. Then add them.

         10x + 24y + 86z = 272

(+)      -10x - 35x - 130z = 365

------------------------------------------

                  -11y - 44z = 637

Now we have an equation with only y and z.

Now, using the simplified original system, multiply the second equation by 7 and the third equation by 2. Then add them.

       –14x – 49y – 182z = –511

(+)       14x + 48y + 178z = 504

-------------------------------------------

                    -y - 4z = -7

Now we have a system in 2 unknowns, y and z.

-11y - 44z = 637

-y - 4z = -7

Multiply the second equation by -11 and add to the first equation.

     -11y - 44z = 637

(+)     11y + 44z = 77

-----------------------------

                0 = 714

Since 0 = 714 is false, this system has no solution.

Answers

Answer:

He will make  $53,330

Step-by-step explanation:

In this question, we are tasked with calculating how much Mr Santiago will make in three years.

To calculate the future value of his earnings, we can use the formula for the future value of the salary

Mathematically, the FV = I(1 + r)^t

Where I is the initial amount of $51,000

r is the interest rate which is 1.5% = 1.5/100 = 0.015

t is the time in years which is 3 years

We plug these values into the equation above;

FV = 51,000(1+0.015)^3

FV = 51000(1.015)^3

FV = 53,329.59 which is $53,330 to the nearest whole dollars

Students are selling pies for a school fundraiser. Customers can buy cherry pies and apple pies. Jennifer sold 12 cherry pies and 3 apple pies for a total of 144. Jacob sold 2 cherry pies and 9 apple pies for a total for 126

Answers

Answer: A cherry pie costs 9 and an apple pie cost 12

Step-by-step explanation:

Let an apple pie be represented by a

Let an cherry pie be represented by c

Jennifer sold 12 cherry pies and 3 apple pies for a total of 144. This can be written as:

12c + 3a= 144

Jacob sold 2 cherry pies and 9 apple pies for a total for 126. This can be written as:

2c + 9a = 126

12c + 3a= 144 ............. i

2c + 9a = 126 ........... ii

Multiply equation i by 2

Multiply equation ii by 12

24c + 6a = 288 ........ iii

24c + 108a = 1512 ...... iv

Subtract iv from iii

-102a = -1224

a = 1224/102

a = 12

An apple pie costs 12

From equation i

12c + 3a= 144

12c + (3×12) = 144

12c + 36 = 144

12c = 144 - 36

12c = 108

c = 108/12

c = 9

A cherry pie costs 9

Final answer:

The problem is about solving a system of linear equations. By assigning C to represent the price of a cherry pie and A to represent the price of an apple pie, we created two equations to reflect Jennifer and Jacob's pie sales. Then solve the equations.

Explanation:

The subject of the school fundraiser problem is systems of linear equations. Applying the method of simultaneous equations, we can represent this problem with two equations. Let's represent the cost of a cherry pie as C and an apple pie as A.

For Jennifer's sales, we form the equation 12C + 3A = 144. For Jacob's sales, we form the equation 2C + 9A = 126. To solve this system of equations, we can use substitution or elimination. These equations are a representation of the fact that each pie type has a consistent price, irrespective of who is selling it or how many of each are sold.

Answer:

1,787.75

Step-by-step explanation:

The sum of the areas of the 10 rectangles gives the surface area of the cushion:

A  = 140 sq. in. + 80 sq. in. + 121 sq. in. + 2(605 sq. in.) + 22 sq. in. + 2(68.875) sq. in +19 sq. in. + 58 sq. in.

= 140 sq. in. + 80 sq. in. + 121 sq. in. + 1,210 sq. in. + 22 sq. in. + 137.75 sq. in +19 sq. in. + 58 sq. in.

= 1,787.75 sq. in.

The surface area of the cushion is 1,787.75 square inches.

Step-by-step explanation:

Final answer:

To find the most significant difference in Bella's budget, calculate the difference for each category and compare them. For Mary Ann, by subtracting her expenses from her net income of $2,589.10, we determine she can save more than 10% of her income, exceeding her savings goal.

Explanation:

The most significant difference between Bella's actual spending and her budget can be determined by comparing the projected expenses to the actual expenses in each category. You'll first calculate the difference for each category by subtracting the actual amount from the projected amount. These differences should be compared to determine which one is the largest. For Mary Ann's scenario, we can construct a budget table and calculate the possibility of saving 10% of her after-tax monthly income by deducting her monthly expenses from her net income. To do this, you'll start with her net monthly income and subtract each of her monthly expenses to check if there's at least 10% of her income left for savings.

If Mary Ann's net monthly income is $2,589.10, her goal is to save 10% of that amount, which would be $258.91. Once you subtract her expenses which total $2,145 (the sum of rent, cell phone, utilities, cable TV and internet, groceries, entertainment, car payment, and gasoline) from her net income, you're left with $444.10. Therefore, she can meet her savings goal since $444.10 is more than $258.91. You can use similar steps and considerations for creating and managing a budget based on the cost of living in your area.

How can I factorize the next equation?
[tex]f(x)=x^4+2x^3-9x^2+18x[/tex]

Answers

Step-by-step explanation:

Use grouping.

f(x) = x⁴ + 2x³ − 9x² + 18x

f(x) = x³ (x + 2) − 9x (x + 2)

f(x) = (x³ − 9x) (x + 2)

f(x) = x (x² − 9) (x + 2)

f(x) = x (x − 3) (x + 3) (x + 2)

STATE: Which type of fastfood chain fills orders most accurately at the drivethru window? The Quick Service Restaurant (QSR) magazine drivethru study visits restaurants in the largest fastfood chains in all 50 states. Visits occurred throughout the day, starting at 11:00 A.M and ending at 2:30 A.M . During each visit, the researcher ordered a main item, a side item, and a drink and made a minor special request such as a beverage with no ice. After receiving the order, all food and drink items were checked for complete accuracy. Any food or drink item received that was not exactly as ordered resulted in the order being classified as inaccurate. Also included in the measurement of accuracy were condiments asked for, napkins, straws, and correct change. Any errors in these resulted in the order being classified as innacurate. In 2015, the ethnic category including Del Taco, El Pollo Loco, Fazoli's, Panda Express, Taco Bell, and Taco John's had the fewest inaccuracies, with only 42 of 457 orders classified as inaccurate.
