what is the perimeter, in feet (ft), of a right triangle which has an area of 12 ft^2 and one leg that has a length of 4 ft?
Answers
Answer:
P = (10 + 2√13) ft ≈ 17.21 ftStep-by-step explanation:
A = 12 ft² - area of triangle
a = 4 ft, b - legs of right triangle
c - hypotenuse (third side of triangle)
A = ¹/₂ ab
12 = ¹/₂•4•b
12 = 2b
b = 6 ft
from Pythagorean theorem:
a² + b² = c²
4² + 6² = c²
c² = 16 + 36
c = √52 = 2√13 ft
The perimeter: P = a + b + c
P = 4 + 6 + 2√13 = (10 + 2√13) ft ≈ 10 + 7.21 = 17.21 ft

Answers
Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16

Answers
Before we write 3 paragraphs, we need to solve the equation ourselves using the order of operations.
Order of Operations: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. (PEMDAS)
3 · (10 - 2) + 4²
3 · (8) + 4²
3 · (8) + 16
24 + 16
40
Finally, here's the prompt:
The requirements of the prompt are to show step-by-step how to solve the problem and to explain the order of operations in 3 paragraphs.In order to solve the equation, we have to understand the order of operations, which is the order used in solving expressions. The order of operations are parenthesis, exponents, multiplication, division, adding, and finally subtracting. It's usually abbreviated to 'PEMDAS'.
The first step of solving the equation is solving what's in the parenthesis, which is 10 - 2. By subtracting, you should get 8. The second step is solving the exponents, which is 4 to the second power. to do that, we multiply 4 by itself, so we should get 16. Now, for the third step, we have to multiply 3 x 8 before we add 16 so we follow the order of operations. After multiplying 8 x 3, you should get 24.
Now, all that's left is to add 24 and 16. Our answer should be 40. That's how you solve the equation using order of operations. In this equation, we only used parenthesis, exponents, multiplication, and addition. Even though there was no division or subtracting (besides subtracting in parenthesis), we still follow the order of operations.
Answer: I did Parenthesis, I subtracted 10-2, that gave me 8. Next I did exponents, I multiplied 4 twice or to the 2nd power. That gave me 16. Then I multiplied 3 and 8 and that equals 24. After that the only thing left to do is add 16 and 24 which equals to 40. That's how I got my answer by using PEMDAS. I followed the order of operations even though I didn't have to use division.
Write the equation for the following table:
X. Y.

Answers
Answer:
\( y = 4x + 3 \)
Step-by-step explanation:
The equation of the table of values given can be written as \( y = 4x + 3 \) .
When x = 0,
\( y = 4(0) + 3 \)
\( y = 0 + 3 = 3\) this corresponds with what we have in the table above.
Let's try another.
When x = 2,
\( y = 4(2) + 3 \)
\( y = 8 + 3 \)
\( y = 11 \)
This also corresponds with what we have in the table.
Therefore, the equation of the table given is \( y = 4x + 3 \) .

Tim, because each point is fraction 3 over 8 unit away from 0

Joe, because the points are at different locations

13.14cm²
Step-by-step explanation:
First we find the area of the rectangle, based on the diagram, this rectangle measures 10cm by 1cm, or 10cm².
After that we find the area of the half circles, In this case I'm going to assume the half circles have the same diameter. The diameter in 2cm, and the radius is half of the diameter. Sine you need the radius to find the area of the circle we will divide the diameter by 2. So 2 ÷ 2 is 1. Then with this radius we will use the formula for the area of a circle, πr².
3.14(1)²
3.14cm²
In most half circles you would divide by two cince this formula calculates the area of a full circle, but two identical half circles is the same as one full circle.
Add the area of the half circles to the area of the rectangle and you get your answer!
10cm²+3.14cm²=

How did you decide where to place your line of best fit? Describe your reasoning.

Answers
Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.
So basically the units are counting up by 5.
The x axis is age in years and y axis is the number of US states named in 60 seconds.
Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.
(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5
