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?
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.

Volume is lxwxh, 6x9= 54, and 54x3=162
Answer: 3
Step-by-step explanation:
The equation for volume of a rectangular prism is lwh. We have the lh and 6 times 9 is 54. Now we just divide 162 and 54 and that's the width which is 3. And to double check 3 times 9 times 6 is 162 :)

John has a box of nails. The box contains 65 small nails, 40 medium nails, and 45 large nails. Susan has a box of nails that has the same proportion of small, medium, and large nails as John's box. There are 176 medium nails in Susan's box.
What is the total number of nails in Susan's box?
Answer:

From question:
Susan has a box of nails that has the same proportion of small, medium, and large nails as John's box =Meaning same ratio
John ratio. Susan
s : m : L s : m : L
65 : 40 : 45. 13 : 8 : 9
13 : 8 : 9. x : 176 : y
x = (176/8)*13
=286
y = (176/8) * 9
= 198
Total number of nails in Susan box
= x + 176 + y
= 286 + 176 + 198

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:
1) = 2hrs and 30mins
2) = 130miles
Step-by-step explanation:
1) 60mi/hr, total driven 150miles
so at 120miles thats 2 hours. 30 miles is 30 minutes
60+60+30=150miles
2) 40miles/hr you drove 2 hours at 40 miles
40+40 =80miles
50miles/hr you drove 1 hour st 50 miles
40+40+50 = 130miles
Answer: 1) 2.5 hours, 2) 130 miles
Step-by-step explanation:
To solve both of these problems, let us remember the formula:
Distance = (speed) × (time)
1) Plug in the numbers into the formula:
150miles = (30miles/hour) × (time)
Divide both sides by 30miles/hour to solve for time:
150miles/(30miles/hour) = time
Simplify:
2.5hours = time
2) Susan's driving is broken into two parts with different speeds and time.
Solve the distance for first drive by plugging numbers into formula:
Distance = (40miles/hour) × (2hours)
Multiply:
Distance of first drive = 80miles
Solve for distance of second drive:
Distance = (50miles/hour) × (1hour)
Multiply:
Distance of second drive = 50miles
Add distance of first drive and second drive:
80miles + 50miles = 130miles
Hilary is ordering a large circular pizza from her local pizza shop. She asks about the size of the pizza and is given three different values: 14 inches, 44 inches and 7 inches.
Hilary knows three measurements that are used to describe circles: radius, diameter and circumference. Which value best matches each measurement? Explain your reasoning.
Answer:
7 is the radius
14 is the diameter
44 is the circumference
Step-by-step explanation:
7 is the smallest number of them all so it's the radius. The diameter is double of a radius so 14 is the diameter and finally 44 is the circumference :)

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
