Step-by-step explanation:
The triangle on the right side fits into the missing part of the left side.
So what I did is (5+4) and times 10 = 90m.
P.s:If I'm wrong I'm sorry.
Step-by-step explanation:
well, it is a rectangle, where an isoceles right-angled triangle is cut off in the top left corner, but that triangle is added to the top right corner.
so, the area is the same as the regular rectangle.
we know, the area of a rectangle is
length × width
now, we know the length for sure (10 m).
what is the width ?
we know the part of the width until the triangle is 5 m.
and we know the leg length of the triangle is 4 m.
the width is simply the sum of the basic part and the leg length
5 + 4 = 9 m
so the area of all this is
10 × 9 = 90 m²

A study done at a polling organization Randomly surveyed 1031 adults by phone. The poll found that 42% of the respondents said they spend less than three hours a day watching TV. Based on this finding calculate to 2 decimals places the ((% confidence interval for the proportion of US adults who spend less than three hours watching TV on an average day.
Answer: To calculate the % confidence interval for the proportion of US adults who spend less than three hours watching TV on an average day, we can use the following formula:
p +/- z*(sqrt(p(1-p)/n))
Where:
p = proportion of US adults who spend less than three hours watching TV on an average day (0.42)
z = standard normal score for a given level of confidence (e.g. for a 95% confidence level, z = 1.96)
n = sample size (1031)
Plugging in the given values, we get:
0.42 +/- 1.96*(sqrt(0.42*(1-0.42)/1031))
Simplifying, we get:
0.42 +/- 0.0156
So the 95% confidence interval for the proportion of US adults who spend less than three hours watching TV on an average day is approximately (0.40,0.44)
So the answer is (0.40,0.44)

A checkout clerk at a department store is expected to complete 16 transactions every hour. In the past 20 minutes, he completed 6 transactions. Choose True or False for each statement. If the clerk continues at the same rate, he will meet his goal of 16 transactions in 1 hour. Choose... At his current rate, the clerk will complete 12 transactions in 1 hour. Choose... At his current rate, the clerk will complete 9 transactions every half hour. Choose... If the clerk continues at this rate for a 6-hour shift, he will complete 96 transactions. Choose...
Step-by-step explanation:
16 transactions per hour (60 minutes).
in short :
16/1
or 16/60 (for minutes instead of 1 hour)
in 20 minutes 6 transactions.
so,
6/20
hour many transactions then in 1 hour (60 minutes) ?
60 = 20×3
so, to bring the ratio to 1 hour (60 minutes) we need to multiply the denominator by 3. and to keep the ratio value, we need to to do the same thing also to the numerator.
therefore,
6/20 × 3/3 = 18/60
so, the clerk will do 18 transactions per hour.
he will meet his goal of 16 : true
he will even exceed but definitely meet his goal.
12 transactions in 1 hour : false
9 transactions every half hour : true
as he will do 18 transactions in 1 hour, he will do half of these transactions (9) in half an hour.
96 transactions in 6 hours : false
18/1
6 = 1×6
so, with the same trick as above we get
18/1 × 6/6 = 108/6
and we see, he would complete 108 transactions in a 6- hour shift.
96 would be right, if the actual ratio would be 16/1 :
16/1 × 6/6 = 96/6

Round your final answer to the nearest tenth. **
Angle D= Angle E= Angle d=
Answer:
Step-by-step explanation:
Using the Law of Cosines, we can find the remaining angle measures of the triangle.
Angle D = cos-1[(25^2 - 8^2 - (25^2 * cos(131°)))/(-2*8*25)] = 20.5°
Angle E = cos-1[(8^2 - 25^2 - (8^2 * cos(131°)))/(-2*25*8)] = 61.4°
Angle F = 180° - (20.5° + 61.4°) = 98.1°
Round to the nearest tenth:
Angle D = 20.5°
Angle E = 61.4°
Angle F = 98.1°

Option 1: Solving by Factoring
Please explain in detail the strategy, Solving by Factoring, discussed in the lesson Quadratic in Form Polynomials. Include an example with this explanation to clearly explain the process.
Answer:
Step-by-step explanation:
Solving by factoring is a strategy used to solve quadratic in form polynomials, which are equations that can be written in the form of ax^2 + bx + c = 0. The goal of this strategy is to factor the equation into two binomials that are equal to zero. Once the equation is factored, we can use the zero product property to set each binomial equal to zero and solve for the roots or solutions of the equation.
The process of factoring begins by finding the greatest common factor of all the terms in the equation. Once the GCF is identified, it can be factored out of the equation. Next, we look for two binomials that multiply to give the remaining terms in the equation and add to give the remaining constant term.
For example, consider the equation: 3x^2 + 6x - 9 = 0.
To factor this equation, we first find the GCF of all the terms, which is 3. We can factor out 3 from all the terms, giving us: 3(x^2 + 2x - 3) = 0.
Now, we look for two binomials that multiply to give x^2 + 2x - 3 and add to give -2. We can see that (x-3)(x+1) satisfies this condition.
By factoring the equation, we have now factored the polynomial into (x-3)(x+1) = 0. We can use the zero product property to set each binomial equal to zero and solve for the roots: x-3 = 0 and x+1 = 0. The solutions are x=3 and x=-1.
By using the factoring strategy, we were able to solve the quadratic in form polynomial 3x^2 + 6x - 9 = 0 and find the roots x=3 and x=-1. This strategy can be applied to any quadratic in form polynomial and is a useful tool in solving equations.

What is the value of y that makes T Parallel to U
Answer: y = 18
Sentence: The value of y that makes T Parallel to U is 18.
Step-by-step explanation:
We are given 3 expressions:
(7x)(6y + 9)(3x + 36)We know that since the angle (7x) is on the same line as the angle (3x + 36), we can therefore determine that they correspond to each other. I referred an image to help demonstrate this concept. So since they correspond to each other, that means they have the same value (meaning they are equal to each other).
We can set both expressions equal to each other.
7x = 3x + 36
And solve:
7x = 3x + 36
-3x -3x
4x = 36
/4 /4
x = 9
now we know the value of x, we can plug it into one of the equations. We can plug it in to 3x + 36 to help with the process in solving y.
3(9) + 36 = 63 degrees
Since 6y + 9 and 3x + 36 (63 degrees) are supplementary angles, we can subtract 180 from 63.
180 - 63 = 117
now we know that 117 degrees = 6y + 9 BUT!, we need to solve for y, because that's what the question is asking for.
So lets solve for y:
117 = 6y + 9
-9 -9
108 = 6y

The number of quarters Dalton has is 5.
How to find the number of quarters?Dalton has $3.05 in dimes and quarters. He has 13 more dimes than quarters. Therefore, the number of quarters he has can be calculated as follows:
Hence, using system of equation,
Therefore,
