5.2 metres in length I think
Step-by-step explanation:
you didnt exactly put a question, but this seems like a problem where you have to divided the volume by the width to find the length, so 260 divided by 50 is 5.2. I apologize if it is wrong, like I said, there wasn't a question so i was confused.
PLEASE HELP ME QUICKLY!! The graph shows the number of eggs a farmer collected from each chicken pen one morning. How many more eggs were collected from pen 3 than from pen 2 & 5? (Each egg = 5 eggs)
Answers
Answer:
Pen 2 = 5 eggs
Pen 3 = 25 eggs
Pen 5 = 10 eggs
It is asking how many MORE eggs does pen 3 have from BOTH pens 2 and 5. Add 2 and 5. But remember one egg = 5 eggs so as stated in the beginning pen 2 has 1 egg which equals 5 eggs and pen 5 has 2 eggs which equals 10.
5 + 10 is?
15, exactly. So how many more eggs does pen 3 have? 15 + one more egg is 20 and pen 3 has 25 which is more than 20 so let’s add another egg which again equals 5.
Now we have 25 eggs, the exact amount pen 3 has. The answer is 2 more eggs/10 more eggs.

Step-by-step explanation:
The longest side of a triangle cannot be longer than the sum of the two shorter sides. So if the 5cm and 12cm sides are the shorter sides, the third one cannot be longer than the 17cm. ... So 12cm is not longer than 5cm plus the length of the third side, and therefore the missing side cannot be shorter than 7cm.

$34.58, and the cost for using 24 HCF is $53.83. What is the cost for using 19 HCF of water?
Answers
Answer:
The monthly cost (in dollars) of the water use (in dollars) is a linear function of the amount of water used (in hundreds of cubic feet, HCF)
---------
The cost for using 28 HCF of water is 39.49, and the cost for using 47 HCF is 65.14.
---
You have 2 points: (28,39.49) and (47,65.14)
slope = (65.14-39.49)/(47-28) = 1.35
y = mx+b
39.49 = 1.35*28 + b
b = 1.69
Step-by-step explanation:
C(x) = 1.35x + 1.69
--------------------------
What is the cost for using 32 HCF of water?
C(32) = 1.35*32 + 1.69
C(32) = $44.89

Answers
Answer: 96∘
Step-by-step explanation:
The measure of angle U is 96°.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
s = 150 cm
t = 430 cm
u = 470 cm
The Cosine rule of a triangle.
a² = b² + c² - 2bc Cos A
Now,
u² = s² + t² - 2st Cos U
Cos U = (s² + t² - u²) / 2st
Cos U = (22500 + 184900 - 220900) / 129000
Cos U = -0.10
U = 95.7
U = 96°.
Thus,
The angle U is 96°.

Out of some students appeared in an examination,
80% passed in English, 75% passed in Science and
5% failed in both subjects. If 300 of them were
passed in both subjects, how many students were
appeared in the examination? Find it by using a
Venn-diagram
(Ans: 500
Answers
Answer:
500 students appeared in the examination.
Step-by-step explanation:
Each event represents a set in the Venn diagram, and we use it to find the desired values.
I am going to say that:
Event A: Passed in English.
Event B: Passed in Science.
80% passed in English
This means that [tex]P(A) = 0.8[/tex].
75% passed in Science
This means that [tex]P(B) = 0.75[/tex]
5% failed in both subjects.
This means that 100% - 5% = 95% passed at least one of these subjects, so [tex]P(A \cup B) = 0.95[/tex].
Proportion that passed both subjects:
This is [tex]P(A \cap B)[/tex]
These percentages are related by the following equation:
[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B)[/tex]
So
[tex]P(A \cap B) = 0.8 + 0.75 - 0.95 = 0.6[/tex]
Number of students in class:
60% of the total number t passed both subjects. This is equals to 300. So
[tex]0.6t = 300[/tex]
[tex]t = \frac{300}{0.6}[/tex]
[tex]t = 500[/tex]
500 students appeared in the examination.
