Answer:
419ft squared
Step-by-step explanation:
Split the shape into one rectangle and one square. I would cut it off along the middle of the L right before the 23ft sign.To find the area of the rectangle, you multiply the length by the width. The length of the rectangle is 26ft, and the width is 13ft.26 • 13 = 338.The area of the square is similar. The measurements of the square are 9ft each, and 9 • 9 = 81.The last step is to add the two areas (338 + 81)If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
Answer:
Step-by-step explanation:
Split the shape into two rectangles as shown in the attachment.
Rectangle I
length = 23 ft
Width = 9 ft
Area I = length * width
= 23*9
= 207 ft²
Rectangle II:
length = 13 ft
Width = 26 -9 = 17 ft
Area II = 13 * 17
= 221 ft²
Area of the entire polygon = 207 + 221
= 428 ft²

What is inequality?
It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
We are given four number inequalities:
30 > 10
30 < 10
10 > 30
10 < 30
The first number sentence, "30 > 10", is true, since 30 is greater than 10.
The second number sentence, "30 < 10", is false, since 30 is not less than 10.
The third number sentence, "10 > 30", is false, since 10 is not greater than 30.
The fourth number sentence, "10 < 30", is true, since 10 is less than 30.
Therefore,
We would circle the first and fourth number sentences as true, and cross out the second and third number sentences as false.

Step-by-step explanation:
Testing for a disease can be made more efficient by combining samples. If the samples from people are combined and the mixture tests negative, then samples are negative. On the other hand, one positive sample will always test positive, no matter how many negative samples it is mixed with. Assuming the probability of a single sample testing positive is , find the probability of a positive result for samples combined into one mixture. Is the probability low enough so that further testing of the individual samples is rarely necessary?
Answer:
The probability of testing positive for one is 0.20.
The probability of testing negative for one sample is (1-0.2)=0.8.
We only save time when all five are negative, which has a probability of 0.8^5=0.32768.
This means that the expected number of tests is
combined sample tests negative = 1 with probability 0.32768
combined sample tests positive = 1+5 retests = 6 with probability 0.67232
Expected number of tests
=Σ nipi / n
=(1*0.32768+6*0.67232)/5 [divide by 5 because we tested 5 samples]
= 0.87232 < 1
So yes, there is a saving.
Note: In practice, all medical tests are not absolute, i.e. they give false-positives(α) and false-negatives (β). The ratios 1-α and 1-β are respectively measures of specificity and sensitivity.
These two parameters complicate the simplistic evaluation above.

Answer:
gradient = -1
Step-by-step explanation:
identify the y intercept ( the point where it meet the y- axis ) which denoted by c in the formula y =mx + c
in the graph :the y- intercept is 5 (c)
take the coordinate of any point that passes through the line :- for example (2,3)
in (2,3), the value of x is 2
the value of y is 3
using the formula y = mx + c find m with is the gradient ( unknown )
y = mx + c
3 = m2 + 5
2m + 5 = 3
we sent + 5 to the right and it changes sign to become -5
2m = 3 -5
we substract -5 from 3
2×m = -2
we send 2 to the other side so that m can be alone, it change to become divide since it was multiply
m = -2 ÷ 2
m = -1
the gradient ( unknown ) = -1

Provide a detailed description of the given transformation.
Answer:
Look below.
Step-by-step explanation:
The following shape is being reflected across the y-axis.
To confirm this, we can check the coordinates.
When something is reflected across the y-axis, its points' y-coordinate don't change. Upon evaluation of the given transformation, we can see that the y-coordinate does not change for any point.
Now, we check the x-coordinate. The x-coordinate MUST be the opposite of the original x-coordinate...
-2 --> 2
-4 --> 4
0 --> 0
-4 --> 4
-2 --> 2
All of the x-coordinates are opposites, and the y-coordinates remained the same, therefore this figure is being reflected across the y-axis.
if 176 dollars = 100 pound and 1 Pound equals to rupees 119 find what is the dollar for nrs.8925
Answer:
Answer:
NRs. 8925
Step-by-step explanation:
176 dollars = 100 pounds
132 dollars = ??? pounds
Using cross-multiplication, we get:
176 dollars x ??? pounds = 100 pounds x 132 dollars
??? pounds = (100 pounds x 132 dollars)/ 176 dollars
??? pounds = 75 pounds
Now, 1 pound = NRs. 119
So 75 pounds = NRs. ???
Using cross-multiplication again, we get:
1 pound x NRs. ??? = NRs. 119 x 75 pounds
NRs. ??? = (NRs. 119 x 75 pounds)/1 pound
NRs. ??? = NRs. 8925
So the answer is 8925 Nepali rupees

Solution:
Note that:
y = -x + 1630 = 2x + ySubstitute the value of y into the equation to find x.
30 = 2x + y=> 30 = 2x - x + 16=> 30 = x + 16=> 30 - 16 = x=> x = 14Substitute the value of x into any equation to obtain the value of y.
30 = 2x + y=> 30 = 2(14) + y=> 30 = 28 + y=> 30 - 28 = y=> y = 2Putting the values in (x,y) form.
(x,y) ⇒ (x = 14,y = 2) ⇒ (14,2)3 folders cost $2.91.

1.94 is the cost for 2 folders if 3 cost $2.91
What is the slope and y-intercept? 20 points!!
Answer:
Slope = 2
Y-intercept = -4
Step-by-step explanation:
The slope of a function is found by finding the change in the y-values and dividing it in the change in x-values.
The change in y-values is 2 because that is the difference between each given data point. The change in x-values is 1 for the same reason.
The slope would be 2/1 which is just 2.
The y-intercept can be found by setting up the function in slope-intercept form (y=mx+b) and using the given data to solve for b. The point I chose to do this with was (2,0)
y=mx+b
y=2x+b
0=(2*2)+b
0=4+b
b=-4
So the slope is 2 and the y-intercept is -4.

Answer:
45.7 meters
Step-by-step explanation:
15 = 6 + 7y
9 = 7y
y = 1.3
The two lengths are still the same, so you can set the two parts equal to the whole. Now that you have y you can substitute it in and add all the sides together.
3y + 7y + 3y + 6y + 6 +15 = P
3(1.3) + 7(1.3) + 3(1.3) + 6(1.3) + 6 + 15 = P
P = 45.7 meters

Find the solution(s) for x in the equation below. (x + 4)(x - 12) = 0
Answer:
-4 or 12
Step-by-step explanation:
(x + 4)(x - 12) = 0
so
x + 4 = 0 OR x - 12 = 0
x + 4 = 0 leads x = -4
x - 12 = 0 leads x = 12
Answer:
x = -4 or x = 12
Step-by-step explanation:
(x + 4)(x - 12) = 0 means:
(x + 4) = 0 or (x - 12) = 0
x + 4 = 0
Subtract 4 from both sides:
⇒ x + 4 - 4 = 0 - 4
⇒ x = -4
x - 12 = 0
add 12 to both sides:
⇒ x - 12 + 12 = 0 + 12
⇒ x = 12
Therefore the solutions are x = -4 or x = 12
