Answer:
-2.14 or -15/7
Step-by-step explanation:
5.9x - 4.2 = 9.4x + 3.3
[combine like terms]
[when going across the equation, + becomes -, vice versa]
-4.2 - 3.3 = 9.4x - 5.9x
-7.5 = 3.5x
[isolate x]
[when going across the equation, * becomes /, vice versa]
-7.5 / 3.5 = x
-2.14 = x [decimal]
-15/7 = x [fractional]
growth of a particular type of plant. He is testing the effects of four growth factors: lighting, age, temperature, and humidity. Here are the levels he's testing for each
The level of each growth factor is an illustration of a combination
There are 90 ways of combining one level from each growth factors
How to determine the number of combinations?From the complete question (see attachment), we have the number of levels in each growth factor is:
Lighting = 3
Age = 5
Temperature = 2
Humidity = 3
So, the number of combination (n) is:
n = 3 * 5 * 2 * 3
n = 90
Hence, there are 90 ways of combining one level from each growth factor.

Answer:
TWO CRACKERS
Step-by-step explanation:
I'm assuming they want to find x. Here we see that these two are similar triangles, so the sides are reflective. 5x/5 should be equal to 4/x, so 5x/5 = 4/x. If we use cross multiplying we get 5x^2 = 20. divide both sides by 5 and we get x^2 = 4 or x = 2.

The average rate of growth for human hair is about 0.3 millimeters per day. How many days will it take a hair that is 12 millimeters long to grow to be 16.5 millimeters?
It will take 15 days for the hair to grow from 12mm to 16.5mm
What do you mean by average rate?By "average rate" in this context, we mean the typical or usual amount of hair growth per unit of time, which is often measured in millimeters per day. This rate can vary slightly depending on factors such as age, gender, genetics, diet, and overall health.
Let's first find out how much the hair needs to grow by subtracting its initial length (12mm) from its target length (16.5mm):
16.5mm - 12mm = 4.5mm
Now we can divide this growth by the average rate of hair growth to find the number of days it will take to grow this much:
4.5mm ÷ 0.3mm/day = 15 days
Therefore, it will take 15 days for the hair to grow from 12mm to 16.5mm.

one third of a number algebraic expression; one third of a number n; one third of a number is 12; one third of x; one third of a number calculator; one third of a number m; how to write one-third of x; how to calculate 1/3 of a number
One-third of the number 12 is 36.
Let x be the number. Then, (1/3)x=12. x=36.
Algebraic Expression: The expression which is made up of variables and constants, with some algebraic operations like addition, and subtraction...is called Algebraic Expression.
Any of the following:
x÷3,x/3,1/3x.
Let the number be x
To find one-third of a number, divide the number by 3 x÷3
This can be also written as x/3
or it can also be expressed as 1/3x
One-third is equivalent to the fraction: 1/3. Therefore, it is a third of the amount. Thirds must be calculated by dividing by 3.For example:
One-third of 24 is 1/3 of 24 = 24/3 = 8.
Five thirds of 15 = 5/3 of 15 = 5 x 15/3 = 5 x 5 = 25.

Find the value of X.
Answer:
X = 5
Step-by-step explanation:
Angles on a straight line=180°
180-151=29°
sum of angles in a triangle= 180°
11x-1+20-3+29=180
11x+20x-3-1+29=180
31x+25=180
31x=180-25
31x=155
divide both sides by 31
X=5
(11x-1)°= 55-1= 54°
(20x-3)°= 100-3= 97°
54°+97°+29°=180°

Dylan hit the ball 48 out of the 60 times he was up to bat. The rest of the time, he snuck out. Approximately what percent did dylan strike out?
Answer:
20 percent
Step-by-step explanation:
(I had such a good explanation and accidentally refreshed the page)
So basics
48/60 is in
12/60 is out
Now we focus on out
we know this 12/60 becuase 48 is in and there are 60 tries so 60-48=12
So now 12/60 into a percent
A percent is basically x/100
So we gotta make 12/60 into a fraction with a denominator of 100
SO simplify fto make it easier (try to get it to 4,2,5,10,50,25 anything that goes into 100)
1/5
1/5 is 20 percent

Harold and Maude plan to take a cruise together, but they live in separate cities. The cruise departs from Miami, and they each book a flight to arrive in Miami an hour before they need to be on the ship. Their travel planner explains that Harold's flight has an 80% chance of making it on time for him to get o the ship and that Maude's flight has a 90% chance of making it on time. Assume that the event of Harold making it on time is independent of the event of Maude making it on time. What is the probability that at least one of Harold and Maude will make it to the cruise
Answer:
98% probability that at least one of Harold and Maude will make it to the cruise
Step-by-step explanation:
Independent probabilities:
When two events are independent, the probability of the two events happening simultaneously is the multiplication of each probability.
Probability that none makes it to the cruise:
Harold's flight has an 80% chance of making it, so 100 - 80 = 20% probability of missing.
Maude's flight has a 90% chance of making it on time, so 100 - 90 = 10% probability of missing.
Both missing: 0.2*0.1 = 0.02.
2% probability of both missing.
Probability that at least one makes it to the cruise:
Either both miss, or at least one makes it. The sum of the probabilities of these events is 100%. So
2 + p = 100
p = 98%
98% probability that at least one of Harold and Maude will make it to the cruise

Solve the equation. -5(-4+2n)=-10(n-2)
Answer:
0 = 0 means that there are infinite solutions.
Step-by-step explanation:
Equation is -5(-4+2n)=-10(n-2)
1. Distribute the -5 and -10
20 -10n = -10n + 20
2. Subtract 20 from one side to the other to get only 1 variable on 1 side.
-10n = -10n
3. divide -10 to separate the variable from the constant.
n = n
This means there are infinite solutions.

Step-by-step explanation:
Simplifying all terms in 1, we get 1, 2, -2, 1/16. So the correct order is -2, 1/16, 1, 2. So the answer is C
Simplifying all terms in 2, we get 6, sqrt30, 1, and 4. While we can't completely simplify sqrt30 easily, we know that 5 squared equals 25 and 6 squared equals 36. 30 is in between, so we can assume sqrt30 is in between 5 and 6. So the answer is d.
Simplifying all terms in 3, we get 1/125, sqrt3, 1, and 0. Again, we can assume sqrt3 is between 1 and 2. So the answer is e.
Simplifying all terms in 4, we get 32, sqrt101, 25, sqrt399. We can assume sqrt101 is close to sqrt100, which is 10. We can also assume that sqrt399 is close to sqrt400, which is 20. So the answer is a.
