1 Define the perimeter of any closed two-dimensional shape.
2 Hence, calculate the perimeter of the figure above.
Work out m and c for the line: 5 x − 3 y + 4 = 0
Step-by-step explanation:
5x - 3y + 4 = 0
we rearrange it to look like this:
y = mx + c
3y = -4 - 5x
we can also write it like this so it rhymes with the formula
3y = -5x - 4
y = -5x - 4 / 3 (the division sign is dividing all the numbers and not only 4 ).
Soo..
y = -5x/3 -4/3
y = mx. + c
so
m = -5/3
c = -4/3.
Hope this helps.
Good luck ✅.

the line plot is entitled weight of science books in pounds. it goes from 2 pounds to 3 pounds with marks at some numbers:
one mark is at two and one eighth. two marks are at two and one fourth. one mark is at two and three eighths. two marks are at two and one half. three marks are at two and three fourths. one mark is at two and seven eighths. question
sonya carried ,begin emphasis,all,end emphasis, the books weighing 2 and one-fourth pounds and 2 and three-eighths pounds to the library. how many pounds of books did sonya carry?
The total pounds of science books that sanya carried is; 6⁷/₈ pounds
How to Interpret Line Plots?
From the attached Line Plot, we can see the book weights.
Now, we are told that Sanya carried all the books weighing 2¹/₄ pounds and 2³/₈ pounds.
From the line plot we see that;
Number of books weighing 2¹/₄ pounds are 2 books
Number of books weighing 2³/₈ pounds is 1 book
Thus;
Total weight of books carried by Sanya = 2(2¹/₄) + 1(2³/₈)
Total weight = 4¹/₂ + 2³/₈
Total Weight = 6⁷/₈ pounds

2. What is the circumference of the circle?
e) 26π cm²
g) 6767 cm²
f) 52π cm²
h) 1697 cm²
Answer:
26π cm
Step-by-step explanation:
the circumference (C) of a circle is calculated as
C = πd ( d is the diameter )
= π × 26
= 26π cm
▶︎◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◀︎
[tex]Hello[/tex] [tex]There![/tex]
We are looking for the circumference of the circle.
It's not hard, I promise! I will take you through a few steps, and we'll find the answer.
Are you ready? Then let's begin...:)
[tex]Procedure:[/tex]
First, we need a formula for the circumference. We can't find the circumference without a formula!
· Luckily, there is a formula for the circumference:
⇒ [tex]C=\pi d}[/tex]
Whoa. What's that?!
No worries, I'll clarify everything in a moment. :)
We are looking for the circumference.
In this formula, what stands for the circumference?
That's right, [tex]C[/tex].
Now, what is this: [tex]\pi[/tex]?
This letter stands for pi - a constant in maths that comes in handy when we're searching for the circumference of a circle (or area).
It has an infinite number of digits after the decimal point, and these digits never repeat!
You might be thinking, "Oh no! Are we really going to use that infinite number?!"
The answer is "No". Mostly, we use 3.14 for [tex]\pi[/tex], because these are the first three digits of pi, but since we aren't asked to use 3.14 for pi, we just press the [tex]\boxed{\pi }[/tex] button on our calculator.
Whew!
And then last but not least, we see "d". This isn't a constant, this is the diameter.
Checking our provided information, we see that the diameter is 26 cm.
Now, we substitute 26 for d:
[tex]\bold{C=\pi (26)}[/tex]
[tex]\bold{C=\pi *26}[/tex]
And now all we have to do is type these numbers into our calculator, and find the answer:
[tex]\bold{C\approx81.7\:cm}[/tex]
Hooray! We've found the circumference!
But wait - why isn't 81.7 an option?
Because what we need to do is write it in terms of pi, which is even easier, because we just substitute 26 for d:
[tex]\bold{C=\pi *26}[/tex]
➢ Rearrange the order of the terms:
[tex]\bold{C=26\pi \:cm}[/tex]
▲ Circumference
Now there's another thing - why are all four options with units squared?
Circumference isn't measured in units squared, the area is!
▶︎ Incase you need the area, here it is:
[tex]\bold{A=\pi r^{2}}[/tex]
A=Area (what we're looking for)
[tex]\pi[/tex] = pi
Here we have a new variable - it's r, which is the radius.
Do you see that [tex]^2[/tex] next to r? It means that r is squared, or multiplied by itself.
You might be thinking, "But we don't have the radius!"
If we have the diameter, finding the radius is a piece of cake, because we divide the diameter by 2:
[tex]\bold{26\div2}[/tex]
[tex]\bold{13}[/tex]
Now we substitute 13 for r and evaluate:
⇒ [tex]\bold{A=\pi (13)^{2}}[/tex]
13 times itself is 169:
⇒ [tex]\bold{A=169\pi \:cm^{2}}[/tex]
Whew! We're finally done!
hope it's helpful!wishing you a great day!
[tex]Greetings![/tex]

Bob bikes to work 8 miles each day. The trip takes him 0.5 hours. If Bob bikes at a constant rate, what is his biking speed? A. 5 mph B. 8 mph C. 16 mph D. 40 mph
Given the distance covered and the time elapsed, if the bike is at a constant rate, the speed of Bob's bikes is 16 mph.
Option C) is the correct answer.
What is Speed?Speed is simply referred to as distance traveled per unit time.
Mathematically, Speed = Distance ÷ time.
Given the data in the question;
Distance covered d = 8milesTime elapsed t = 0.5hrsSpeed of the bike S = ?Speed = Distance ÷ time
Speed = 8miles / 0.5hrs
Speed = 16 mph
