To find what number of DNA samples were not bacteria we have to find what was 47% of the 15,152 samples first.
We can do this by multiplying 0.47 x 15,152 = 7,121.44
Now 7,121.44 is 47% of the samples that DOES have bacteria. To find out how many do not we must subtract.
15,152 - 7,121.44 = 8,030.56
So the number of DNA samples that were not bacteria were 8,030.56.
GOOD LUCK! :)

Solve For in P in the scientific formula PV=nRT
To solve this problem you must apply the proccedure shown below:
1. You have the following formula given in the problem above:
[tex]PV=nRT[/tex]
3. Then, to solve for P you only need to move V from the left member to the right member. V is multiplying P, therefore, it will divide [tex]nRT[/tex], as you can see below:
[tex]PV=nRT\\P=\frac{nRT}{V}[/tex]
Therefore, the answer is: [tex]P=\frac{nRT}{V}[/tex]

Eva sees a dolphin 3.2 meters below sea level and a bird 47/10 meters above sea level. Which of the following expressions represents the vertical distance between the dolphin and the bird?
Answer:
Vertical distance between dolphin and the bird is 7.9 meters.
Step-by-step explanation:
Eva sees a Dolphin at the distance 3.2 meters below the sea level.
At the same time she sees a bird [tex]\frac{47}{10}[/tex] meters above the sea level.
Therefore, vertical distance between the dolphin and the bird = Distance of dolphin below the sea level + Distance of the bird above the sea level
= 3.2 + [tex]\frac{47}{10}[/tex]
= 3.2 + 4.7
= 7.9 meters
Answer is 7.9 meters.

The Yu family and the Sainz family went on vacation together and each family leased a car. The leasing company charged a flat rental fee for the week, plus a charge for each mile driven. The Yu's drove 222 miles; their car cost $110.30 for the week. The Sainz's drove 147 miles; their car cost $99.05. What is the linear equation that represents the cost of a rental car? Round to the nearest hundredth
Answer:
y = 0.15x+77 is the equation linear connecting total cost y and miles driven x
Step-by-step explanation:
Given that the leasing company charged a flat rental fee for the week, plus a charge for each mile driven.
Let flat rental fee be c and cost per mile driven = m and miles driven = x
Total cost =y
Then y = mx+C is the linear equation.
to find m and c, we use the fact that y =110.30 when x = 222
i.e. 110.30 = c+222x
and similarly 99.05 = c+147x
Subtract to eliminate c
11.25 = 75 x
0.15 =x
Substitute in I equation
110.30 = c+222(0.15)
c = 77
Hence y = 0.15x+77 is the equation linear connecting total cost y and miles driven x
Answer:
y = 0.15x+77
Step-by-step explanation:
C is directly proportional to d such that c=1.5d.
find c when D=12: First you have to plug in the number so if d=12 the you do c=12(1.5) which equals 18. C=18
Find d if C=15: you now have to do the inverse operation. if c=d1.5 then d= c/1.5 Then plug in the numbers again, d=15/1.5 it equals 10, so d=10

In August Emily’s clothing store sold 460 shirts with the ration of short sleeve to long sleeve being 3:7. How many short sleeve shirts where sold?
Emily's clothing store sold 138 short sleeve shirts, calculated by dividing the total shirts by the sum of the ratio parts (10) and multiplying the result by the short sleeve part of the ratio (3).
The question asks how many short sleeve shirts were sold if the ratio of short sleeve to long sleeve shirts is 3:7 and a total of 460 shirts were sold. To find the answer, first calculate the total parts of the ratio by adding both parts of the ratio together, which is 3+7=10.
Then, divide the total number of shirts by the total parts of the ratio to find out how many shirts each part of the ratio represents: 460/10=46. Since the ratio of short sleeve shirts is 3 parts, multiply the number each part represents by 3 to get the number of short sleeve shirts: 46*3=138. Therefore, Emily's clothing store sold 138 short sleeve shirts.

An apparel company uses a trucking service to deliver products from its warehouse to its retail outlets. For a one-way trip, the trucking company charges a flat rate of $250 per truck, plus $1.25 for every mile driven. The apparel company has a budget of less than $950 per trip. The apparel company’s owner wants to find out which retail outlets can be serviced with the given requirements.
Represent this situation in an inequality.
Answer:
The inequality will be: [tex]x<560[/tex] , where [tex]x[/tex] is the distance of the retail outlets from the warehouse.
Step-by-step explanation:
For a one-way trip, the trucking company charges a flat rate of $250 per truck, plus $1.25 for every mile driven.
Suppose, the number of miles driven is [tex]x[/tex]
So, the charge for [tex]x[/tex] miles will be: [tex]\$1.25x[/tex]
and the total charge for a one-way trip will be: [tex]\$250+\$1.25x[/tex]
Given that, the apparel company has a budget of less than $950 per trip.
So, the inequality will be.........
[tex]250+1.25x<950\\ \\ 1.25x<950-250\\ \\ 1.25x<700\\ \\ x<\frac{700}{1.25}\\ \\ x< 560[/tex]
Thus, the retail outlets which are less than 560 miles away from warehouse can be serviced with the given requirements.

What is -4(7x+5)=-160
Answer is -23
Add 4 from both sides
Subtract 5 from both sides
Then divide 7
To get rid of the parantheses we must multiply -4 times anything inside the parantheses.
-4(7x+5)=-160
-28x-20=-160
Add 20 to both sides of the equation.
-28x-20=-160
-28x=-140
Divide both sides by -28
-28x/-28=-140/-28
x=5

Question 5(Multiple Choice Worth 4 points) The legs of a right triangle are 12 centimetres and 16 centimeters. What is the length of the hypotenuse? 15 centimeters 17 centimeters 20 centimeters 28 centimeters
For this type of question, you have to use the Pythagorean Theorem:
[tex]a^{2} +b^{2} = c^{2}[/tex]
In the theorem, a and b are the legs. To find the length of the hypotenuse, you have to square the lengths of the two legs and add it together. Then, find the square root of the sum.
First square both numbers.
[tex]a=12 \\ a^{2} = 12 \times 12 = 144[/tex]
[tex]b = 16 \\b^{2} = 16 \times 16 = 256[/tex]
Now that you have the numbers, you need to add them.
[tex]144+256=400[/tex]
Now you need to find the square root of 400 to find the length of the htypotenuse.
[tex]\sqrt{400} = 20[/tex]
The length of the hypotenuse is 20 cm, which is the 3rd choice
a. 15 cm x
b. 17 cm x
c. 20 cm ✔

The volume of a cylindrical soap dispenser is modeled by the expression below.select the true statement.a. the expression (x + 1)2 represents the height of the soap dispenser.b. the expression (x + 1)2 represents the radius of the soap dispenser.c. the factor 4x + 1 represents the height of the soap dispenser.d. the factor 4x + 1 represents the area of the base of the soap dispenser.
Answer:
The expression [tex](x+1)^2[/tex] represents the radius of the soap dispenser.
The expression [tex]4x+1[/tex] represents the height of the soap dispenser.
Step-by-step explanation:
The question says that the soap dispenser is in the form of a cylinder.
Now, we find the volume of the cylinder by using the given formula:
[tex]V= \pi r^2 h[/tex], where V represents the volume, 'r' represents the radius, and 'h' represents the height of the cylinder.
Now, the volume is the product of radius squared and the height, if they both are functions of [tex]x[/tex], then the function to represent the volume must have cubic exponents.
Since, the radius is squared in the formula and it is a function of [tex]x[/tex] that implies that the function of radius must have square as the exponent of [tex]x[/tex], therefore, the expression [tex](x+1)^2[/tex] will represent the radius of the soap dispenser and the expression [tex](4x+1)[/tex] represents the height of the soap dispenser.

You multiply by 1.12 to find your answer
Answer: 1.12
To get this answer, you would represent 12% as 0.12 (move the decimal point 2 spots to the left to go from 12.0% to 0.12) then you add on 1 to get 1+0.12 = 1.12
Another way to think about it is to have 100% + 12% = 112%, so the new price is 112% of the old price. For example, if the car was $100 and you increase the price by 12%, then it jumps to $112. Notice how 1.12*(old price) = 1.12*100 = 112 = new price

Multiplicative Inverse
EXPLANATION
If we multiply any number by its multiplicative inverse, the result is 1.
So for the given equation
[tex]3\times N=1[/tex]
[tex]N[/tex] is the multiplicative inverse of [tex]3[/tex]. That is why the result is [tex]1[/tex]
Answer:
C. Multiplicative inverse.
Step-by-step explanation:
We have been given an equation [tex]3\cdot N=1[/tex]. We are asked to find the name of N.
We can see that N is multiplied by 3 and the result is 1.
We know that a number is known as multiplicative inverse of another number, when the product of both numbers equal to 1.
Since product of 3 and N is 1, therefore, N is multiplicative inverse for our given equation.
