Answer:
10 meters²
Step-by-step explanation:
Method 1 ~
This method adds the triangle with the two rectangles.
----------------------------------------------------------------------------------------------------------
First find the area of the largest rectangle ~
Width = 4 meters - 2 meters = 2 meters
Length = 3 meters
Area = Width × Length = 2 meters × 3 meters = 6 meters²
Then find the area of the second rectangle ~
Width = 1 meter
Length = 2 meters
Area = Width × Length = 1 meter × 2 meters = 2 meters²
Then find the area of the triangle ~
Base = 3 meters - 1 meter = 2 meters
Height = 2 meters
Area = [tex]\frac{bh}{2}[/tex] = [tex]\frac{2*2}{2}[/tex] = [tex]\frac{4}{2}[/tex] = 2 meters²
Finally, add the triangle and the two rectangles together ~
6 meters² + 2 meters² + 2 meters² = 10 meters²
Method 2 ~
This method subtracts the triangle from the whole rectangle.
----------------------------------------------------------------------------------------------------------
First find the area of the rectangle ~
Width = 3 meters
Length = 4 meters
Area = Width × Length = 3 meters × 4 meters = 12 meters²
Then find the area of the triangle ~
Base = 3 meters - 1 meter = 2 meters
Height = 2 meters
Area = [tex]\frac{bh}{2}[/tex] = [tex]\frac{2*2}{2}[/tex] = [tex]\frac{4}{2}[/tex] = 2 meters²
Lastly, subtract the triangle with the rectangle ~
12 meters² - 2 meters² = 10 meters²

Solve for the value of r.
Answers
Answer:
r=14
Step-by-step explanation:
7r+6=8r-8
14=r
r=14
Answer:
r = 14
Step-by-step explanation:
Since both angles are equivalent to each other solve for r:
7r + 6 = 8r - 8 (subtract 6 from -8)
7r = 8r - 14 (subtract 8r from 7r)
-r = -14 (divide each side by -1)
r = 14
Then plug the value of r (14) back into both parentheses:
7 * 14 + 6 = 104°
8 * 14 - 8 = 104°
The final answer is r = 14, and both angles equal to 104°
Which shows the zeros of f(x) = x^2 – x – 2?
A. –1 and –2
B. 1 and –2
C. 1 and 2
D. 2 and –1
Answers
Explanation: To find the zeros of this quadratic function, we can factor or use the quadratic formula.
FACTORING: We need to find 2 numbers that add up to -1 (the coefficient for -x in this function) and multiply to -2 (the constant in this function). -2+1 = -1 and -2•1 = -2. Therefore x^2-x-2 can be factored into f(x)=(x-2)(x+1). To find the zeros, set each factor to zero (x-2=0 and x+1=0) and solve for x. You get 2 and -1.
QUADRATIC FORMULA: The coefficient in x^2 is 1 (a in the quadratic formula), the coefficient of -x is -1 (b in the quadratic formula), and -2 is c in the quadratic formula. Plug all of this into the formula and you get the following: -(-1) plus or minus the square root of (-1)^2 - 4(1)(-2) all over 2(1). Simplify this and you get 1 plus or minus the square root of 9 all over 2. (1+3)/2 is your first zero, 2. (1-3)/2 is your second zero, -1.
Factor the difference of two perfect squares using the X method. An x-method chart shows the product a c at the top of x and b at the bottom of x. What are the two binomial factors for x2 – 25? (x – 5)(x – 5) (x 5)(x 5) (x – 20)(x 5) (x – 5)(x 5).
Answers
By using x-method we got that factorization [tex]x^2-25[/tex] is (x+5)(x-5)
What is factorization ?factorization is writing a expression as a product of several factors.
So Given polynomial is
[tex]x^2-25[/tex]
Now we will factorise this using x method
Here a=1 b=0 and c= -25
so ac=-25
Now We will write -25 at the top.
and 0 at the bottom.
No we will find two numbers that multiply to the top number -25 and add to the bottom number 0. Hence those numbers are -5 and 5.
Now we can write equation as
[tex]x^2-5x+5x-25\\\\x(x-5)+5(x-5)\\\\(x+5)(x-5)[/tex]
By using x-method we got that factorization [tex]x^2-25[/tex] is (x+5)(x-5)

The 90% confidence interval would be given by (63.330;81.070)
Step-by-step explanation:
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Let put some notation
x=left arm , y = right arm
x: 175 169 182 146 144
y: 102 101 94 79 79
Since the Confidence is 0.90 or 90%, the value of a = 0.1 and a/2= 0.05we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.05,4)".And we see that ta/2= 2.13

Explanation: add 5 and 4, you get 9. divide 54 by 9, and you get 6.
Answer:
$30 and $24
Step-by-step explanation:
Hello! We can rewrite ratios as 5x:4x because essentially we can put x in for any value and it would still be the same ratio (10:8, 15:12). So we will put x there just to make it easier to understand.
You know that the ratio of 5x:4x adds up to 54. And, now that we have the x, we can do a nifty trick. We can add 5x and 4x to get 9x. Now we have 9x = 54. If we simplify this, we get x = 6.
Now that we have x = 6, we can plug in that value in the ratio 5x:4x. 5 * 6 = 30 and 4 * 6 is 24
And that is exactly your answer: 30 and 24 dollars respectively
If you want to test it, you can add the two numbers to see if it adds to the number you want it to. After that, you can put it in a ratio and simplify it to see if it simplifies down to the same ratio. In this case, the two numbers satisfy both conditions.

What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
Blue laser light with a wavelength of 450 nm illuminates two 50-m-wide slits positioned 0.25 mm apart. On a screen 2.0 m behind the slits, the interference pattern is visible.
For dark fringe, the equation as:
yp = p λ L / d
for p =1
yp = λ× L/a
For bright fringe, the equation as:
ym = m λL / d
from (i) and (ii)
For missing order, the equation as:
ym = yp
m λL / d = λ× L/a
m=d/a
m = 0.25×10⁻³/ (50×10⁻⁶)
m=5
The number of bright fringes, the equation as:
N-1=2(m-1)
N-1 = 2×4
N = 8 + 1
N=9
