--- Strep throat is caused by Streptococcus bacteria. The amount of bacteria multiplies at a rate of 10^13 per 10^2 hrs. What is the average growth of bacteria per hour?
The average growth of the bacteria per hour is [tex]10^{11}[/tex].
To find the average growth of bacteria per hour, we need to determine the rate at which the bacteria multiply per hour.
Given:
The amount of bacteria multiplies at a rate of [tex]\(10^{13}\)[/tex] per [tex]\(10^2\)[/tex] hour.
We want to find the growth rate per hour.
First, let's find out how much the bacteria multiplies per hour:
If the bacteria multiply by [tex]\(10^{13}\)[/tex] in [tex]\(10^2\)[/tex] hours, then the average growth per hour can be found by dividing the total growth in [tex]10^{13[/tex] hours by [tex]10^2[/tex].
So, the growth per hour is:
Growth per hour} = [tex]\frac{10^{13}}{10^2}[/tex]
Growth per hour} = [tex]10^{13 - 2}[/tex]
Growth per hour} = [tex]10^{11}[/tex]
Therefore, the average growth of bacteria per hour is [tex]10^{11}[/tex].

the product of two consecutive even integers is 48 find the integers
The required integers are -8 and -6, or 6 and 8 whose the product of two consecutive even integers is 48
What are Integers?Integers are defined as the collection of Whole Numbers and the negative values of Natural Numbers make up an integer.
Let the two consecutive even integers be 2n and 2(n+1), where n = any integer.
As per the given condition, The product of the two integers is 48
2n × 2(n+1) = 48
Multiply out, and subtract 48 from both sides
4n2+4n-48=0
Divide both sides by 4
n²+n-12=0
Factor the quadratic
(n+4)(n-3)=0
n= -4 and +3
For n= -4, 2n = -8 and 2(n+1) = -6. (-8)(-6) = 48
For n=3, 2n = 6 and 2(n+1) = 8. (8)(6) = 48
Thus, the required integers are -8 and -6, or 6 and 8.

What is the equation in point slope form of a line that passes through the points (-8,2) and had a slope of 1/2
Answer:
[tex]y-2=\dfrac{1}{2}(x+8)[/tex]
Step-by-step explanation:
It a line passes through the point [tex](x_1,y_1)[/tex] with slope m, then the point slope form of the line is
[tex](y-y_1)=m(x-x_1)[/tex] ....(i)
It is given that line passes through the point (-8,2) and had a slope of 1/2.
We neeed to find the equation in point slope form of the line.
Substitute [tex]x_1=-8,y_1=2\text{ and }m=\dfrac{1}{2}[/tex] in equation (i).
[tex](y-(2))=\dfrac{1}{2}(x-(-8))[/tex]
[tex]y-2=\dfrac{1}{2}(x+8)[/tex]
Therefore, the point slope form of the line is [tex]y-2=\dfrac{1}{2}(x+8)[/tex].
Miss Marcus Bulletin Board is 7 ft long and 4 feet High she has 26 ft of board to use Miss Marcus pool supplies 7 time 4 equals 28 to find the exact amount of the board she needs she concludes that she does not have enough border board for the bulletin board do you agree
Final answer:
Yes, I agree that Miss Marcus does have enough board for the bulletin board for the given information
Explanation:
The student is trying to determine if Miss Marcus has enough board to use for her bulletin board. The student calculates the area of the bulletin board as 7 ft x 4 ft = 28 ft². However, the student concludes that Miss Marcus does not have enough board because she only has 26 feet of board to use. This is incorrect, as 26 ft is greater than 28 ft². Therefore, Miss Marcus does have enough board for the bulletin board.
Deepak is a landscaper who charges $30 for each job he does plus an additional $15 for each hour he works. He only accepts jobs if he will earn at least $90 the job. He writes this inequality to determine x, the number of hours he must work during each job in order to accomplish this.
Answer:
A.) Deepak can only accept jobs that last 4 or more hours.
Step-by-step explanation:
Hope this helps :)
add a thanks...
Deepak must work 4 or fewer hours to earn at least $90 per job.
Explanation:The question is asking about the inequality that Deepak, a landscaper, writes to determine the number of hours he must work during each job in order to earn at least $90 the job. We can break down the equation as follows:
Let x be the number of hours Deepak works.
The equation can be written as: $30 + $15x ≤ $90.
To solve for x, we subtract $30 from both sides: $15x ≤ $60.
Then, we divide both sides by $15: x ≤ 4.
Therefore, Deepak must work 4 or fewer hours to earn at least $90 per job.

i need to solve this equation: x= r-h/ y
for h and then for r
Answer:
[tex]h=r-xy[/tex]
[tex]r=xy+h[/tex]
Step-by-step explanation:
[tex]x=\frac{r-h}{y}[/tex]
Solve the equation for h
We need to get 'h' alone
[tex]x=\frac{r-h}{y}[/tex]
multiply y on both sides
[tex]xy=r-h[/tex]
Now add h on both sides
[tex]xy+h=r[/tex]
Subtract xy from both sides
[tex]h=r-xy[/tex]
Now solve the equation for 'r'
[tex]x=\frac{r-h}{y}[/tex]
multiply y on both sides
[tex]xy=r-h[/tex]
Now add h on both sides
[tex]xy+h=r[/tex]
[tex]r=xy+h[/tex]
A plumber charges $55 for a service call plus $35 per hour. If the plumber's bill was $160, how many hours was he there?
Answer:
Plumber worked for 3 hours.
Step-by-step explanation:
A plumber charges $55 for a service call plus $35 per hour.
Let he works for x hours.
Then for x hours of work charges = $35x
Since plumber charges $55 as a fixed charge so the total charges will be = 55 + 35x
This total amount charged by the plumber equals to $160
and the equation representing this situation will be
55 + 35x = 160
35x = 160 - 55
35x = 105
x = [tex]\frac{105}{35}[/tex]
x = 3 hours
Therefore, he worked for 3 hours.

9514 1404 393
Explanation:
Each is a reflection of the other over the x-axis. Their x-coordinates are the same, so they lie on the same vertical line. Their y-coordinates are opposites, so they are equal and opposite distances from the x-axis.
In the talent show, 6 students plan to sing, 7 students plan to dance, and 2 students plan to tell jokes. Rick said that the ratio of singers to joke-tellers is 6 to 2. Leah said that the ratio of joke-tellers to singers is 1 to 3. Who is correct? Explain why.
Leah is correct because the ratio of 6 singers to 2 joke-tellers simplifies to 3 to 1. When we reverse this ratio to represent joke-tellers to singers, it becomes 1 to 3, which is what Leah stated
The question is asking us to compare two different ratios and decide which one is correct. Rick stated the ratio of singers to joke-tellers is 6 to 2. In its simplest form, this ratio can be reduced to 3 to 1 when we divide both numbers by 2. On the other hand, Leah stated the ratio of joke-tellers to singers is 1 to 3, which is the inverse of the first ratio.
Since the ratio of singers to joke-tellers is indeed 6 to 2, which simplifies to 3 to 1, that means for every 3 singers, there is 1 joke-teller. Therefore, Leah's statement of the ratio is correct, as it provides the simplified form while Rick gives the unsimplified form. The order of terms in a ratio is important, and Leah's presentation maintains the correct order while also presenting the simplest form of the ratio

1.56 x 10 to the 4th power in Standard notation
To write 1.56 × [tex]10^{4}[/tex] in standard notation, we will first begin with
1.56. Next, we look at the exponent. The exponent is 4 so this tells us we need to move the decimal point 4 places to the right.
1.56 → 15600.
Therefore, 1.56 × [tex]10^{4}[/tex] is written in standard notation as 15,600.
