A triangle with a height of 12in.²has an area of 36 in.² how long is the base of the triangle
Answer: 6
Step-by-step explanation:
Area = ½base × height
36 = ½b × 12
½b = 36/12 =3
Base = 3× 2
Answer:
[tex]6in.^{2}[/tex]Step-by-step explanation:
To find the area we need to multiply length*height.
Because a triangle is half of a square we need to divide the area by two.
12*6=72
72/2= 36

The function
p(w)=230(1.1)
represents the number of specialty items produced at the old factory w
weeks after a change in management. The graph represents the number of specialty items produced at the
new factory during the same time period.
(a) During Week 0, how many more specialty items were produced at the old factory than at the new
factory? Explain.
(b) Find and compare the growth rates in the weekly number of specialty items produced at each factory.
Show your work.
Answer: Is In The Explanation
Step-by-step explanation: For the answer to the question above,
A) You just fill in 0 for w in the problem and anything raised to the power of 0 is 1, so 230(1) is 230, and that is the old factory and at 0 for the new, it is at 190. Subtract then explain why you did what you did.
B) I believe what they are asking for you to do, is you can take each week from the new factory and subtract it and find the equation for the new factory, you already know the growth rate for the old factory= 230(1.1)^w.
C) You take your old factory's equation and plug in numbers until one of them is greater at the new factory.
A circle has a diameter of 12 inches what is the best approximation of its area use 3. 14 to approximate for pie
Answer:
113.04 square inches
Step-by-step explanation:
The diameter of the circle is 12 inches, so the radius is (1/2) * 12 = 6 inches. The area of this circle is approximately 3.14(6^2) = 3.14 * 36 = 113.04 square inches.
What is worse Precalculus or AP Computer Science Principles?? I have to decide which class i want.
Answer:
This question kind of illogical, if it's a one before the other kind.
Explanation:
Computer scince priniples, especially AP, will most likely involve some equations and potential coding. Most of the numbers and coding will most likely involve some level of calc. Even if they didn't, this class indicates that you most likely wish to get into a form of computer science as a career, perhaps computer animation or engineering. Regardless of the path, some understanding of calculus would be immensly helpful in the future if not now. At the end of the day, it really is your call and not some people on a homework helping site, but I would choose precalc.
Note: Im not you, I don't know what you want in life, i'm just guessing here. Regardless, I believe you'll make the best descision my friend :).
5. List three numbers that have square roots that are whole numbers greater than 12.

if the sum of a number and seven is doubled, the result is eight less than the number. Find the number
Answer: -18
Step-by-step explanation:
Let the number be represented by x.
If the sum of a number and seven is doubled, the result is four less than the number. The expression would be
2(x + 7) = x - 4
We would open the bracket on the left hand side of the equation by multiplying each term inside the bracket by 2. It becomes
2x + 14 = x - 4
Subtracting 14 and x from the left hand side and the right hand side of the equation, it becomes
2x + 14 - 14 - x =x - x - 4 - 14
x = - 18
Answer:
-22
Step-by-step explanation:
The result is eight less than the number means that
the result = number - 8
( x + 7 ) * 2 = x - 8
=> 2x + 14 = x - 8
=> x = -22

2. The population of a school is 800 students and is increasing at a rate of 2% per year. Write an
exponential growth function, then find the population of the school after 9 years.
Answer:
1.) y=800e^(0.02t)
2.) 957.76 (or 958 if rounding up is required)
Step-by-step explanation:
1.) Since the increase is in years and our time is in years, we can use the function y=Pe^(rt) where P is our beginning value, r is rate (as a decimal) and t is time. Substitute the values P=800, r=0.02 to get y=800e^(0.02)t.
2.) Solving the equation above, we substitute t for 9, we get:
Y=800e^(0.02*9)
Y=800e^(0.18)
Y=800*(1.1972)
Y=957.76
Since it asks for population, you may or may not need to round to 958.

John is w years old. His sister is 16 years old and his brother is twice johns age all three siblings have a total age of 31
Answer:
Step-by-step explanation:
John's age = w
His brother's age = 2*w = 2w
His sister's age = 16 years
Total age of all siblings = 31
w + 16 + 2w = 31
w + 2w + 16 = 31
Combine like terms
3w + 16 = 31
Subtract 16 from both sides
3w = 31 - 16
3w = 15
w = 15/3
w = 5
[tex]\boxed{\text{John's age = 5 years }}[/tex]
His brother's age = 2w
= 2*5
= 10
[tex]\boxed{\text{John's brother's age = 10 years}}[/tex]

What is the solution to the system of equations below?
y = negative 3 x + 5 and y = 4 x minus 2
Answer:
(1, 2)
Step-by-step explanation:
Since we are finding a solution that matches both equations, y = -3x + 5 is equal to y = 4x - 2.
So -3x + 5 = 4x - 2
Then group terms like so by moving them to the other side:
5 + 2 = 4x + 3x
7 = 7x.
Therefore x = 1.
Now to find y we substitue the value of x into an equation that contains y:
Y = 4x - 2
{x = 1}
Y = 4 - 2
Y = 2
Therefore the solution is (1, 2)
