Answer:
1. 1 5/7
2. 2/15
Step-by-step explanation:
1. 4/1 × 3/7= 4 times 3, 1 times 7 = 12= 1 5/7
2. 2/9 × 3/5= 2 times 3, 9 times 5= 6/45= 2/15
Answer:
3466
Step-by-step explanation:
9.6% of 36, 100 is 3465.6
rounded is 3466
Lets say the race is x km long.
That means she ran 65% of x.
And that also means that 65% of x = 3
So 65%*x=3
65/100x=3
x=3*100/65
x=300/65
x=4.62
Answer:
The beam will bend by 50 mm with a mass of 100kg?
Step-by-step explanation:
The first step in solving the problem of direct variation is setting up the relation mathematically.
We can do this as follows:
The bending of the beam varies directly as its mass.

here is the symbol representing direct variation. To remove this and replace it with an equality sign, we have to introduce a constant of proportionality, k

k = 20 /40 = 0.5
We can now use this to find the distance the beam will bend with a mass of 100kg?
This will be

There fore, the beam will bend by 50 mm with a mass of 100kg?
