4 m
12 m
5m
60 m ²
120 m 2
106 m ²
68 m 2
Answer:
68 square meters
Step-by-step explanation:
The hexagon is made up of two trapezoids. Use the formula to find the area of each trapezoid then add those two areas together.
Area of a trapezoid (add the two bases together, multiply by the height then divide by 2):
[tex]A = \frac{1}{2} (b_{1}+b_{2})h[/tex]
Top trapezoid:
[tex]A = \frac{1}{2} (5 + 12)4\\A = \frac{1}{2} (17)4\\A= \frac{1}{2} (68)\\A = 34[/tex]
Bottom trapezoid (identical to the top trapezoid):
[tex]A = \frac{1}{2} (5 + 12)4\\A = \frac{1}{2} (17)4\\A= \frac{1}{2} (68)\\A = 34[/tex]
Add the areas together:
34 + 34 = 68
A Pythagorean triple is a set of three positive integers a, b, and c that satisfy the equation a² + b² = c².
The numbers 3, 4, and 5 are a Pythagorean triple because 3² + 4² = 5². Pythagorean triples are usually written in parentheses, such as (3, 4, 5) .
You can determine other Pythagorean triples by multiplying every number in (3, 4, 5) by the same positive integer. This creates similar triangles where the number you multiplied every triple by is the scale factor.
To create Pythagorean triples that are not similar to a triangle with side lengths of 3, 4, and 5, follow these steps.
Choose two positive integers, m and n, where m>n .
Determine a using a=m2−n2 .
Determine b using b=2mn .
Determine c using c=m2+n2

The probability of rain on the last day of July is 95 % . If the probability remains constant for the first seven days of August , what is the probability that it will rain at most two of those seven days in August ? Find the Mean , Standard Deviation , and Variance .
The probability that it rains at most 2 days is 0.00005995233 and the variance is 0.516
The probability that it rains at most 2 daysThe given parameters are:
Number of days, n = 7Probability that it rains, p = 95%Number of days it rains, x = 2 (at most)The probability that it rains at most 2 days is represented as:
P(x ≤ 2) = P(0) + P(1) + P(2)
Each probability is calculated as:
[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]
So, we have:
[tex]P(0) = ^7C_0 * (92\%)^0 * (1 - 92\%)^{7 - 0} = 0.00000002097[/tex]
[tex]P(1) = ^7C_1 * (92\%)^1 * (1 - 92\%)^{7 - 1} = 0.00000168821[/tex]
[tex]P(2) = ^7C_2 * (92\%)^2 * (1 - 92\%)^{7 - 2} = 0.00005824315[/tex]
So, we have:
P(x ≤ 2) =0.00000002097 + 0.00000168821 + 0.00005824315
P(x ≤ 2) = 0.00005995233
Hence, the probability that it rains at most 2 days is 0.00005995233
The meanThis is calculated as:
Mean = np
So, we have:
Mean = 7 * 92%
Evaluate
Mean = 6.44
Hence, the mean is 6.44
The standard deviationThis is calculated as:
σ = √np(1 - p)
So, we have:
σ = √7 * 92%(1 - 92%)
Evaluate
σ = 0.718
Hence, the standard deviation is 0.718
The varianceWe have:
σ = 0.718
Square both sides
σ² = 0.718²
Evaluate
σ² = 0.516
This represents the variance
Hence, the variance is 0.516

Answer:
1) Area of frame: [tex]140cm^2[/tex] ; Area of picture: [tex]40cm^2[/tex] ; Total Area: [tex]180cm^2[/tex].
2) Area 1 = [tex]48cm^2[/tex] ; Area 2 = [tex]12cm^2[/tex] ; total area = [tex]60cm^2[/tex] [first answer line : [tex]60cm^2[/tex]]
Step-by-step explanation:
1. So to answer this question, you have to find the inner photo area first (which you will then subtract from the overall rectangle area to get the photo frame area).
To find area, you multiply length x width. For this question, there are not enough measurements given to initially multiply length and width. So, assuming that the photo is centered on the frame and the frame width is consistent along all sides, you find the difference between the overall length (12) and the picture length (5).
12 - 5 = 7
The leftover area (outside of the picture) is 7 cm (half of seven on both sides), so one side can be assumed to be : 3.5 cm
this means that 15 cm - 3.5 cm of both sides lengths (difference between the two lengths given) is the height of the photo, 15 - 3.5(2) = 8
So, the dimensions/measurements of the photo are 5 cm by 8 cm.
This means that the inner photo area is 40 (5 x 8) cm
The area of the frame will be the area of the total rectangle [12 x 15] - the inner photo area [40]. [ (12)(15) - 40 ]
[180 - 40] = 140 cm
(area is measured in squared units, so the area of the frame should be written as [tex]140cm^{2}[/tex] ; and the area of the photo should be written as [tex]40cm^{2}[/tex])
The total area is the entire area of the rectangle: (12)(15) = 180. (This should be written as [tex]180cm^2[/tex])
--------------------------------------
2) Finding the area of a shape that isn't a simple rectangle is easier if you separate the shape into smaller rectangles. I will separate the two rectangles into 4 x 12 and 2 x 6 [6 cm would be the remaining side length if you remove the length of 4].
{you can separate the shape in multiple ways, so my answer is only one answer to this problem out of other splits.}
as mentioned, the area is length x width.
4 x 12 = 48.
2 x 6 = 12. Once again, you should write area in squared units.
(the area 1 should be written as [tex]48cm^{2}[/tex] ; the area 2 should be written as [tex]12cm^2[/tex])
you can combine the separated areas (add them) to find the total area. 48 + 12 = 60.
(the total area should be written in squared units also, so the total area should be written as: [tex]60cm^2[/tex])
The area of the figure is [tex]60cm^2[/tex]

Problem 13
x = central angle = 360-105 = 255 degrees
r = 8 = radius
A = sector area
A = (x/360)*pi*r^2
A = (255/360)*pi*8^2
A = 142.41887
I used the calculator's stored value of pi to get the most accuracy possible.
Round that decimal value however you need to. The same applies to the other questions as well.

Answer: Approximately 259.41176 square metersAnswer:
13) 142.4 in²
14) 6.0 cm
15) 259.4 m²
Step-by-step explanation:
Formula
[tex]\textsf{Area of a sector of a circle}=\left(\dfrac{\theta}{360^{\circ}}\right) \pi r^2[/tex]
(where r is the radius and [tex]\theta[/tex] is in degrees)
Question 13Given:
r = 8 in[tex]\theta[/tex] = 360° - 105° = 255°Substitute the given values into the formula and solve for A:
[tex]\implies \textsf{Area}=\left(\dfrac{255^{\circ}}{360^{\circ}}\right) \pi 8^2[/tex]
[tex]\implies \textsf{Area}=\dfrac{136}{3} \pi[/tex]
[tex]\implies \boxed{\textsf{Area}=142.4\: \sf in^2 \:(nearest\:tenth)}[/tex]
Question 14Given:
Area = 36 cm²[tex]\theta[/tex] = 114°Substitute the given values into the formula and solve for r:
[tex]\implies 36=\left(\dfrac{114^{\circ}}{360^{\circ}}\right) \pi r^2[/tex]
[tex]\implies \dfrac{36 \cdot 360}{114 \pi}=r^2[/tex]
[tex]\implies r^2=\dfrac{2160}{19 \pi}[/tex]
[tex]\implies r=\sqrt{\dfrac{2160}{19 \pi}}[/tex]
[tex]\implies \boxed{r=6.0\: \sf cm\:(nearest\:tenth)}[/tex]
Question 15Given:
Area = 49 m²[tex]\theta[/tex] = 68°Substitute the given values into the formula and solve for r²:
[tex]\implies 49=\left(\dfrac{68^{\circ}}{360^{\circ}}\right) \pi r^2[/tex]
[tex]\implies \dfrac{49 \cdot 360}{68 \pi}= r^2[/tex]
[tex]\implies r^2=\dfrac{4410}{17 \pi}[/tex]
[tex]\textsf{Area of a circle} = \pi r^2[/tex]
[tex]\implies \textsf{Area of a circle N} =\dfrac{4410}{17 \pi} \cdot \pi[/tex]

Solve √x-1= x-3. Check for extraneous solutions.
A.No solution
B.x=2,5
C.x=5
D.x=2
Answer is C x=5
Step-by-step explanation:
so, "- 1" is also part of the square root ?
sqrt(x - 1) = x - 3
it is clear that for any value x < 1 we have no solution in R (as this makes the argument of the square root negative, and there is so real number solution for the square root of negative numbers).
now square the whole equation.
x - 1 = (x - 3)² = x² - 6x + 9
x² - 7x + 10 = 0
the general solution for quadratic equations is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = -7
c = 10
x = (7 ± sqrt(49 - 4×1×10))/(2×1) =
= (7 ± sqrt(49 - 40))/2 = (7 ± sqrt(9))/2
x1 = (7 + 3)/2 = 10/2 = 5
x2 = (7 - 3)/2 = 4/2 = 2
x2 is probably (given the answer options) not a valid solution for the original problem, as it represents the negative solution of sqrt(x - 1).
sqrt(2 - 1) = 2 - 3
± 1 = -1
remember, every square root has always 2 solutions : a positive and a negative one.
your teacher clearly only wanted the positive solution, which is x1 = 5.
so, yes,
C. x = 5
is the correct answer.
but please send your teacher my regards and comments. he/she has to state that only the positive solution to the square root is required/allowed.
because, formally, also x = 2 is a valid solution.
and therefore, C. AND D. are correct answers !!!!

3. The diagonal of a rectangular field is 169 m. Ifthe ratio of the length to the width is 12:5, find the: (a) (b) dimensions; perimeter of the field.
The dimensions of the rectangle are length 156 m and a width of 65m, and a perimeter P = 442m
How to find the dimensions of the rectangle?For a rectangle of length L and width W, the diagonal is:
[tex]D = \sqrt{L^2 + W^2}[/tex]
Here we know that the diagonal is 169m.
And the ratio of the length to the width is 12:5
This means that:
W = (5/12)*L
Replacing all that in the diagonal equation:
[tex]169 = \sqrt{((5/12)^2*L^2 + L^2} \\\\169^2 = (25/144)*L^2 + L^2 = ( 25/144 + 1)*L^2\\\\\frac{169}{\sqrt{25/144 + 1} } = L = 156[/tex]
So the length is 156 meters, and the width is:
W = (5/12)*156 m = 65m
Finally, the perimeter is:
P = 2*(L + W) = 2*(156 m + 65m) = 442m

maxine earns $1250 dollars a month. whats is the maximum amount she should use for budget for housing?
show your work so I know how to do this
Answer:
The National Housing Act of 1937 established guidelines for maximum rents for low-income families. Originally the maximum rent threshold was set at 20%, however this increased to 30% in 1981 (and has remained at this level ever since). This figure is used to determine how much of your gross monthly income you should spend on rent.
The 28% Rule is used for determining how much of your gross monthly income should be used for a mortgage, however the FHA's threshold is a little higher at 31% of your gross monthly income on a mortgage.
Renting:
30% of $1,250 = 0.3 × 1250 = $375
Mortgage 28% Rule:
28% of $1,250 = 0.28 × 1250 = $350
Mortgage 31% FHA:
31% of $1,250 = 0.31 × 1250 = $387.50
Therefore, discounting the higher FHA's threshold, the maximum amount to budget for housing is:

a 2 gallon container of window cleaner costs $11.52. what is the price per cup?
Answer:
$0.36
Step-by-step explanation:
To convert between gallons, quarts, pints, and cups it can be helpful to memorize this:
2 Cups in a Pint
2 Pints in a Quart
4 Quarts in a Gallon
We can work backwards using this, finding that there are 4 quarts in a gallon, 8 pints in a gallon, and 16 cups in a gallon.
Since we have 2 gallons, we must multiply the number of cups by 2 to get 32 cups in 2 gallons.
Now we can solve for the price per cup by dividing the cost of all 2 gallons by how many cups are in it (32.)
$11.52 / 32 = $0.36
That is the answer

Can someone at lest help me with the 2nd question a) b) and c) PLEASE AND THANKYOU
What are the ages of Lilian and May?
Let May's age be represented with m
Lilian's age 2/3m
Ratio of May's age to Lilian's age = m : 2/3m
Multiply both sides by 3 : 3 : 2
Ratio of Lilian's age their total age: 2 : 5
Lilian's age = 2/5 x 25 = 10 years
May's age = 3/5 x 25 = 15 years
What is the total mass of both ingredients?Let the mass of carrots be represented with c
The mass potatoes would be represented with 5/2c
Ratio of carrots to potatoes : 2 : 5
Ratio of the mass of potatoes to the total mass : 5 : 7 = 5/7
Mass of carrots = 5/2c - c = 9
3/2c = 9
3c = 18
c = 6
Mass of potatoes = 5/2 x 6 = 15
Total mass = 15 + 6 = 21 kilograms
