If it takes 4 men 6 hours to repair a road, How long will it take 3 men to do the job if they work at the same rate ?
Answers
Answer:
8 Hours
Step-by-step explanation:
Let the the length of the road x
It takes 4 men 6 hours to repair a road and they work at the same rate.
So, each one will repair 0.25x
And the rate to repair the road will be 6 hour per 0.25x.
rate =
Now, if 3 men will do the job
each one of them will repair (1/3) x with the same previous rate
∴
So, The 3 men will do the job at 8 hours.

The length of one side of the rhombus is 10 units.
What is Rhombus?
A rhombus is a two dimensional shape which consists of four equal sides with opposite side being parallel and opposite angles being equal.
Given that,
EFGH is a rhombus.
Length of the two diagonals are also given.
EG = 16 and FH = 12
In a rhombus, the diagonals bisect each other at right angles.
Let the intersection point of the diagonals be O.
Consider ΔOFG.
Using Pythagoras Theorem,
(FG)² = (OG)² + (OF)²
OG = EG / 2 = 16 / 2 = 8
OF = FH / 2 = 12 / 2 = 6
(FG)² = 8² + 6²
= 100
FG = √100 = 10
Hence the length of one side of the rhombus is 10 units.

Answer:
C. 10 units
Step-by-step explanation:
The half diagonals of a rhombus are the legs of a right triangle with the hypotenuse being the side of the rhombus.
EG and FH are the diagonals of the rhombus. The half-diagonals measure 8 and 6.
We can use the Pythagorean theorem to find the hypotenuse length with is the length of the side of the rhombus.
a^2 + b^2 = c^2
8^2 + 6^2 = c^2
64 + 36 = c^2
100 = c^2
c^2 = 100
c = 10

Hi Lacy
3x²=0
First thing you need to do is to divide both sides by 3
3x²/3 =0/3
x²=0
The last step you need to do is too take the square root of 0
x= √0
x=0

Benjamin travels 420 m in 100 seconds .
Step-by-step explanation:
Given : The tire of his unicycle has a circumference of 2.8 m.
The tire revolves 1.5 times per second
To Find: What is the distance Benjamin travels in 100 seconds?
Solution :
Since we are given that he wheel makes 1.5 revolutions per second.
It makes revolutions in 100 seconds =
=
Thus it makes 150 revolutions in 100 seconds
Now, Each revolution travels 2.8 m.
So, 15 revolutions it will travel =
=
Thus Benjamin travels 420 m in 100 seconds .
Answer:
420m

Given:
weight of math books = 4458 grams
number of math books = 4
1 kg = 1000 grams
4458 grams * 1kg/1000 grams = 4458 kg/1000 = 4.458 kg
4.458 kg * 4 books = 17.832 kg
OR
4458 grams * 4 books = 17832 grams
17832 grams * 1kg/1000 grams = 17832 kg/1000 = 17.832 kg
