Answer:
Perimeter= 20 inches
Step-by-step explanation:
since the perimeter of a plane figure is distance round the shape, we add all the sides in order to get 20inches.
Perimeter= 4+5+4+4+3= 20incjes. That's for the perimeter.
Then area, we divide the shape into two portions sides A and B.
We find the area of side A which is a rectangle so, the are = Length×Breadth..
= 4×5 = 29cm².Side B is a triangle so it's area will be
Answer:
Total Perimeter = 30 in
Total Area: 30 in²
Step-by-step explanation:
First, do the perimeter of the triangle.
Equation: side+side+base = 3 + 4 + 5 = 12
Next is the perimeter of the rectangle.
Equation: 2(length + width) = 2·(5 + 4) = 18
Then, add the two perimeters:
12 + 18 = 30 in (Total Perimeter = 30 in)
Next, do the area of the triangle.
Equation: height • base/2 = 4 · 5/2 = 10
Finally, the area of the rectangle.
Equation: width • length = 4 · 5 = 20
Then, add the two areas:
10 + 20 = 30 (Total Area: 30 in²)

* Which value can you use for n to show that the
first step in a proof by mathematical induction of
"For all the positive integers n
1^2+2^2+...+n^2?
n(n+1) (2n+1)" /6 is true?
A-n=1/4
B- n=1
C- n=3.26
D- n=-10.1
Answers
Answer:
B- n = 1
Step-by-step explanation:
"For all the positive integers n" is a qualifying statement. The number used has to be positive and also must be an integer. Integers are whole numbers and their opposites, so basically no fractions and no decimals. Answer A is a fraction and C is a decimal and D is negative and a decimal. So they don't work for this problem.
The value is n to show that the first step in a proof by mathematical induction of for all the positive integers is 1.
Thus, option B is correct.
The conditions can be checked through the options.
The option C and D will be eliminated because the condition is for all the positive integers n but n is decimal here.
For n = 1/4, the solution will be in fractions.
So, it does not hold true for n= 1/4.
For n = 1
[tex]\dfrac{n(n + 1)(2n + 1)}{6}[/tex]
=[tex]\dfrac{1(1 + 1)(2 \times 1 + 1)}{6}[/tex]
= 1
Thus, the value is n to show that the first step in a proof by mathematical induction of for all the positive integers n is 1.
So, option B is correct.

What is the measure of x
Answers
explanation: just add the interior angles to get the exterior
Answer:
156°
Step-by-step explanation:
the total internal angle of a triangle in 180°
so,
180 - (85 + 71)
= 24°
this is the internal angle, to find the external angle subtract this value from 180
so,
180 - 24
= 156° (answer)

The table below shows the results of the survey: Like Beach Do Not Like Beach Total Like Mountains 36 28 64 Do Not Like Mountains 56 38 94 Total 92 66 158 If a student does not like the mountains, what is the probability that student also does not like the beach? 39. 1% 40. 4% 59. 5% 60. 8%.
Answers
Probability of an event is its chance of . The probability that a student not liking mountains doesn't like beach is: Option b: 40.4%
How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}}[/tex]
Where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
For the given case, from the table (image attached below), we can see that, there are total 94 students who do not like mountains. Now, out of those 94, there are 38 students not liking beach.
Thus, if A = a student not liking beach
B = not liking mountains,
Then ,
P(A|B) = P(A ∩ B)/P(B) = [tex]\dfrac{38/158}{94/158} = \dfrac{38}{94} \approx 0.404 = 40.4\%[/tex]
Thus, probability of a student not liking beach given that that student doesn't like mountains is 40.4% approx.

2 Sami made 27 phone calls in 12 days. Marta made 45 phone calls in 18 days. a Work out the mean number of calls per day for each person. b Who made more calls per day?
Answers
The mean number of calls for Sami is 2.25 calls per day and for Marta it is 2.5 calls per day
The person who made more calls per day is Marta.
What is the mean?Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
Sami = 27 / 12 = 2.25 calls per day

Find the slope
Answers
Answer:
-x + 1 __________________________
Answer:
-1
Step-by-step explanation:
The slope is the change in y over the change in x. In this graph, the y-value decreases by 1 unit to the right, and the x-value increases by 1 unit. So, this means that the slope is represented as -1/1. This can then be rewritten as -1.
We know that this slope is negative because it decreases to the right. Positive slopes increase to the right.

What is the area of a rectangle whose side are x – 3 and x + 5?
Answers
Given :
The sides of a rectangle are (x - 3) and (x -5).To Find :
The area of the rectangle.Solution :-
Here we are given two sides of rectangle . We know that the area of rectangle is ,
→ Area = side 1 * side 2
Substituting the respective values ,
→ A = (x-3)(x+5)
→ A = x(x+5) -3(x+5)
→ A = x² + 5x -3x -15
→ A = x² +2x - 15
Hence the area of the rectangle is x² +2x -15.
