Three ropes of length 2 m 84 cm, 4 m 26 cm and 7 m 10 cm are to be cut into small pieces of equal length. What is the greatest possible length of each equal part, so that there is no wastage? How many pieces are there in total?
Answers
The greatest possible length of each piece is 2 cm.
What is HCF?The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.
Three ropes of length 2 m 84 cm, 4 m 26 cm, and 7 m 10 cm are to be cut into small pieces of equal length.
We have been given the lengths of the ropes as
2 m 84 cm = 284cm
4 m 26 cm = 426cm
7 m 10 cm= 710 cm
We have to determine the greatest possible length of each equal part So that there is no wastage
So the greatest possible length of each piece will be the HCF of the length of the ropes.
⇒ 284 = 2× 142
⇒ 426 = 2 × 213
⇒ 710 = 2 × 355
Hence, the HCF of the 284, 426, and 710 is 2.
Therefore, the greatest possible length of each piece is 2 cm.

The volume of a right rectangular prism is 70 7/8 cubic feet and its base is a square with a side length of 4 1/2 feet. what is the height?
Answers
Answer:
7/2 feet
Step-by-step explanation:
Volume of Right Rectangular Prism: V = w * h * l
You are given the volume, and the base (which would include l and w)- and are told to find h.
70 7/8 cubic feet = 4 1/2 feet * h * 4 1/2 feet (simplify the right side)
70 7/8 cubic feet = 81/4 feet squared * h (divide both sides by 81/4)
7/2 feet = h
The height will be 7/2

Answer:
Step-by-step explanation:
Circumstance of a curcle C=2*pi*r
So if you want to find r from this equation you come up with r=C/2*pi. That's exactly what they give you in the problem.
Now you know that C= 26.69 so replacing what we know in the formula r=C/2*pi you get
r=26.69/2*3.14 =4.25
So looking at the figure you they said r=4.25
That means that the figure is has to be a circle.
Hope that makes sense.

Answer:
8: 73.2 cm
10: 738 mm
Step-by-step explanation:
8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm
10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm
Answer:
8: 73.2
10: 738
Step-by-step explanation:
Area of a trapezoid = [tex]A=\frac{a+b}{2} h[/tex]
where a and b = base lengths and h = height
For #8
These are the given dimensions
Base 1 = 4.5
Base 2 = 7.5
Height = 12.2
All we have to do is plug in the values into the formula
So....
[tex]A=\frac{4.5+7.5}{2} 12.2\\4.5+7.5=12\\\frac{12}{2} =6\\6*12.2=73.2[/tex]
Hence the answer is 73.2cm²
For #10
Once again all we have to do is plug in the values into the formula
[tex]A=\frac{22+19}{2} 36\\22+19=41\\\frac{41}{2} =20.5\\20.5*36=738[/tex]
Hence the answer is 738

Answer:
x = 5
Step-by-step explanation:
4x + 2y + z = 24
2x - 3y - z = 2
5x + y + 2z = 21
-----------------
Eliminate z
Add the 1st and 2nd eqn
4x + 2y + z = 24
2x - 3y - z = 2
----------------
6x - 1y = 26 eqn A
Multiply the 2nd eqn by 2, then add the 3rd.
4x - 6y -2z = 4
5x + y + 2z = 21
----------------
9x - 5y = 25 eqn B
---------------
Now you have 2 eqns in 2 unknowns, not 3.
Multiply eqn A by 5 and subtract eqn B.
30x - 5y = 130 eqn A times 5
9x - 5y = 25 eqn B
-------------
21x = 105
x = 5
Answer:
x = 5 is the answer

If 30% of a number equals 8, find 90% of that number.
Answers
Answer:
8.88
Step-by-step explanation:
I believe it is 8.88 becuase this question is asking to find 90% pf that number.
What do you need to do?
you have to make a proportion.
8/x 90/ 100
You would now cross multiply. 90* x = 90x 8*100= 800
the equation you would need is 90x = 800. divide them and you get 8.88.
ROUNDED: you get 9.

Jasraj left his house and walked 1500 m east to the supermarket. He then walked another 500 m east to the comic store before walking back home the same way he came. How many kilometers did Jasraj walk altogether?
Answers
Answer:
Jasraj walked 4 kilometers all together
Step-by-step explanation:
First, add.
1,500 + 500 = 2,000
Then, multiply by 2.
2,000 × 2 = 4,000
Now, we have to convert to kilometers.
1 kilometer = 1000 meters
4,000 ÷ 1,000 = 4
So, Jasraj walked 4 kilometers!
