Answer: yes this statement is true All functions are relations,but not all relations are functions.
Step-by-step explanation:
Its true because if you think of it like this
a function is a output and like the inner circle
and relations is the outer circle.

David worked 7 1/3 hours today and planted 11 trees. It takes him about the same amount of time to plant each tree. How long did it take him to plant each tree?
Answer:
2/3 hours or 40 mins.
Step-by-step explanation:
No. of trees planted by David = 11
No. of hours worked by David to plant 11 trees = 7 1/3 hours = (7*3 + 1) /3 = 22/3
It takes him about the same amount of time to plant each tree
let time taken to plan 1 tree be x
then time taken to plan 1*11 tree = 11*x
But, given that total time taken is 22/3 hours
thus,
11x = 22/3 hours
x = 22/(3 *11) = 2/3
Thus, it took 2/3 hours to plant each tree.
As 1 hour has 60 minutes
Time taken in minutes to plant 1 tree = 2/3 *60 mins = 40 mins
It takes David 2/3 hours to plant each tree.
Since it takes David 7 1/3 hours today to plant 11 trees.
Therefore time taken to plant 11 trees = 7 1/3 hours = 22/3 hours
The time taken to plant each tree = 22/3 hours ÷ 11 trees = 2/3 hours per tree
Therefore it takes David 2/3 hours to plant each tree.

Answer:the SAS similarity theorem
Step-by-step explanation:
What is the final amount if 1885 is increased by 5% followed by a further 18% increase?
Give your answer rounded to 2 DP.
Answer:
Answer = 2,335.52
Step-by-step explanation:
Given amount : 1,885
Finding 5% of 1,885 = 0.05 * 1,885
5% of 1885 = 94.25
Now 1885 increased by 5% = 1,885 + 94.25= 1,979.25
Finding further 18% of 1,979.25 = 0.18 * 1,979.25
18% of 1979.25 = 356.265
Final amount = 1,979.25 + 356.265
Final Amount = 2,335.515
Now Rounding off the answer to 2 decimal points we get:
Answer = 2,335.52
(As the third digit after decimal is 5 so previous will be added b 1)
Here is the histogram of a data distribution. All class widths are 1.
4
3-
2
1
What is the median of the distribution?
Answer: Option C, the median is 5.
Step-by-step explanation:
The median is the value that is just in the middle of our data set (the possible values in the histogram)
the set is S = {2, 3, 4, 5, 6, 7, 8, 9}
And if we take in account the number of times that each value is repeated, we get:
S = {2, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 6, 6, 7, 7, 8, 9}
So we have 17 values, and the one exactly in the middle will be the median.
To find the point in the middle, we can use that we have 17 values, because 17 is odd, we can do
17 - 1 = 16
16/2 = 8.
17 - 8 = 9.
Then the 9nth point is our median:
the 9th point is a 5.
Then the correct option is C

The probability that any postcard posted in Portugal on Monday is delivered to the UK within a week is 0.62.
The probability that any postcard posted in Portugal on Friday is delivered to the UK within a week is 0.41.
Anna is on holiday in Portugal. She posts 15 postcards to the UK on Monday.
How many of her postcards can she expect to be delivered within a week?
Answer:
She expect 9 postcards to be delivered within a week.
Step-by-step explanation:
We are given that The probability that any postcard posted in Portugal on Monday is delivered to the UK within a week is 0.62
We are also given that The probability that any postcard posted in Portugal on Friday is delivered to the UK within a week is 0.41.
Now we are supposed to find How many of her postcards can she expect to be delivered within a week if She posts 15 postcards to the UK on Monday.
So, The probability that any postcard posted in Portugal on Monday is delivered to the UK within a week =0.62
She expect no. of postcards to be delivered within a week.= [tex]15 \times 0.62[/tex]
She expect no. of postcards to be delivered within a week.=9.3
So, She expect 9 postcards to be delivered within a week.

What is the total surface area of the figure shown?
Answer:
Surface area of the figure = 1000 in²
Step-by-step explanation:
From the figure attached,
Two rectangular prisms A and B have been shown with the dimensions.
Surface area of a rectangular prism = 2(length + width) × height
Surface area of prism A = 2(9 + 10) × 20
= 760 in²
Surface area of prism B = 2(15 + 10) × 8
= 16×25
= 400 in²
But one surface of prism B along the width and the same area of prism A are hidden.
Area of the hidden surfaces = 2(10 × 8)
= 160 in²
Total surface area of the figure = 760 + 400 - 160
= 1000 in²

Which answer choice shows the correct calculation by using the Pythagorean Theorem for the distance of
between Elibri's apartment and Elibri's school, namely HE?
Answer:
|AC| = 4.47 units (question attached as image)
Step-by-step explanation:
The question lacks sufficient details. We wil however consider a similar example (image attached) to understand how to solve questions using Pythagoras theorem.
We will calculate for |AC| using Pythagoras theorem, we have:
|AC|² = |AB|² + |BC|²
|AC| = ?, |AB| = 4 units, |BC| = 2 units
|AC|² = 4² + 2² = 16 + 4
|AC|² = 20 ⇒ |AC| = [tex]\sqrt{20}[/tex]
|AC| = 4.472135955 ≈ 4.47
|AC| = 4.47 units

Instructions: Find the circumference of the circle and round to the nearest tenth.
3.2 yd.
Circumference =
yd.
Can u get help?
Answer:
the answer is 20.1 yd
Step-by-step explanation:
circumference= 2πr
where r is 3.2
pi is 22/7
c = 2/1 × 22/7 × 3.2/1
c = 140.8/7
c = 20.1 yd
The circumference of the circle is 20.12 yd. if the radius of the circle is 3.2 yd the answer is 20.12 yd.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have a circle shown in the picture.
The radius of the circle = 3.2 yd
As we know,
The circumference of the circle can be calculated using the formula:
C = 2πr
Here,
C is the circumference of the circle
r is the radius of the circle
r = 3.2 yd
C = 2π(3.2)
Take π = 22/7
C = 6.4π(22/7)
C = 140.8/7
C = 20.114
After round to the nearest tenth:
≈ 20.12 yd.
Thus, the circumference of the circle is 20.12 yd. if the radius of the circle is 3.2 yd the answer is 20.12 yd.

There were 200 melons in a box and they were distributed to 3 children in the ratio of 4:3:3. The first child sold the melons at 2$ each while the other two sold the melons at 2 for 5$. find the total amount of money collected fro. the sales of all melons.
Answer:
$460
Step-by-step explanation:
let the number of melons be x
4x + 3x + 3x = 200 melons
10x = 200 so, x will be 20
4x = 80 melons
3x = 60
3x = 60
amount made by 1st child = 80 × $2 = 160$
the remaining melons are 60 + 60 = 120
amount collected: they sold them in groups of 2 and each group was $5. so,
120÷2 × $5 = $300
total amount = 300 + 160 = $460.
