8. Kane has 4 pieces of wood available to build a triangle-shaped garden.
Which pieces of wood can he use? Select all that apply*
2ft, 3ft, 4ft
2ft, 3ft, 5ft
2ft, 4ft, 5ft
3ft, 4ft, 5ft
Answers
Using the Triangle Inequality Theorem, we can conclude that the pieces of wood measuring 2ft, 3ft, 4ft, and 3ft, 4ft, 5ft can be used to build a triangle-shaped garden.
To determine which pieces of wood can be used to build a triangle-shaped garden, we need to apply the Triangle Inequality Theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. We will check each set of wood pieces to see if they fit this criterion.
2ft, 3ft, 4ft: Do these lengths satisfy the Triangle Inequality Theorem? Yes, because 2 + 3 > 4, 2 + 4 > 3, and 3 + 4 > 2.2ft, 3ft, 5ft: Do these lengths satisfy the theorem? No, because 2 + 3 is not greater than 5. Therefore, these cannot form a triangle.2ft, 4ft, 5ft: Do these lengths satisfy the theorem? No, because 2 + 4 is not greater than 5. Therefore, these cannot form a triangle.3ft, 4ft, 5ft: Do these lengths satisfy the theorem? Yes, because 3 + 4 > 5, 3 + 5 > 4, and 4 + 5 > 3.Therefore, the pieces of wood that can be used to build a triangle-shaped garden are the ones measuring 2ft, 3ft, 4ft and 3ft, 4ft, 5ft.

An adult takes 800 mg of ibuprofen. Each hour, the amount of ibuprofen in the person's
system decreases by about 32%. How much ibuprofen is left after 5 hours?
Answers
Answer:
116.31468544 mg ibuprofen left
Step-by-step explanation:
Since there are 800 mg at the beginning and the system decreases by about 32% of the ibuprofen
After 1 hour
→ 800 - (800x32/100) = 800 - 256 = 544 mg ibuprofen left
After 2 hours
→ 544 - (544x32/100) = 544 - 174.08 = 369.92 mg ibuprofen left
After 3 hours
→ 369.92 - (369.92x32/100) = 369.92 - 118.3744 = 251.5456 mg ibuprofen left
After 4 hours
→ 251.5456 - (251.5456x32/100) = 251.5456 - 80.494592 = 171.051008 mg ibuprofen left
After 5 hours
→ 171.051008 - (171.051008x32/100) = 171.051008 - 54.73632256 = 116.31468544 mg ibuprofen left
To find the amount of ibuprofen left after 5 hours, the initial 800 mg is multiplied by 0.68 raised to the 5th power, resulting in approximately 115.28 mg remaining.
To calculate the amount of ibuprofen left after 5 hours, we can use the exponential decay formula. Since the amount decreases by 32% each hour, we can represent this as a decay rate of 68% (100% - 32%) remaining each hour. Therefore, the amount of ibuprofen after one hour is 68% of the initial amount, and we can represent this as a multiplication by 0.68 for each passing hour.
The formula to find the amount of ibuprofen left after 5 hours is:
Final amount = initial amount × (0.68)⁵
Using the initial amount of 800 mg and raising 0.68 to the 5th power:
Final amount = 800 mg × 0.68⁵
Final amount = 800 mg × 0.1441
Final amount ≈ 115.28 mg
So, approximately 115.28 mg of ibuprofen is left in the adult's system after 5 hours.

To determine the weight for each animal and their total combined weight, you would need to know the weight of each individual animal. Let's say we have three animals: a lion weighing 200 pounds, a zebra weighing 300 pounds, and a giraffe weighing 500 pounds. To find their total combined weight, you simply add up their weights: 200 + 300 + 500 = 1000 pounds.

Step-by-step explanation:
The expression -2a²b⁴÷4ab⁻⁸ is -1/2ab¹² and expression 5w⁴y⁻²÷-15w⁻⁶y² is w¹⁰/3y⁴
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is -2a²b⁴÷4ab⁻⁸, a≠0, b≠0
We have from properties of exponents that the denominator is multiplied with numerator by changing the sign.
1/aⁿ=a⁻ⁿ
-2a²b⁴/4ab⁻⁸
-1/2a²⁻¹b⁴⁺⁸
-1/2ab¹²
Now the expression is -5w⁴y⁻²÷-15w⁻⁶y²
-5w⁴y⁻²/-15w⁻⁶y²
5w⁴y⁻²/15w⁻⁶y²
1/3w⁴⁺⁶y⁻²⁻²
1/3w¹⁰y⁻⁴
w¹⁰/3y⁴
Hence, the expression -2a²b⁴÷4ab⁻⁸ is -1/2ab¹² and expression 5w⁴y⁻²÷-15w⁻⁶y² is w¹⁰/3y⁴

Mr.Samuel planted 40 pepper plants when he began his garden in 2005. Each year the number of pepper plants doubled. The number of plants,f(x),after x years is modeled with an exponential function
Answers
Answer:
[tex]f(x)=40*2^x[/tex]
Step-by-step explanation:
Mr Samuel Planted 40 pepper plants in 2005.
Therefore:
f(0)=40
Each year the number of pepper plants doubled.
In 2006, f(1)=40*2
In 2007, f(2)=40*2*2[tex]=40*2^2[/tex]
In 2008, f(3)=40*2*2*2[tex]=40*2^3[/tex]
If we continue in like manner. The number of pepper plants after x years will be given by the exponential function:
[tex]f(x)=40*2^x[/tex]
where 40 is the initial number and 2 is the growth factor.

Answer:
942 cm³.
Step-by-step explanation:
To find the volume of the cone, we will need to use the formula: [tex]\frac{1}{3}[/tex]bh.
To find the base, we simply need to find the area of the circle. This is done by using: [tex]\pi r[/tex]².
From this, we get a base area of ≈314 cm².
Now, to find the volume of the cone, we, multiply by the height giving us:
314×9= 2826.
Finally, the last step is to multiply this by [tex]\frac{1}{3}[/tex], resulting in:
2826×[tex]\frac{1}{3}[/tex]= 942.
Therefore, 942 cm³ is the correct answer.
