Q: What is the least they could weigh together?
A: 0.62 kg
=================================================
Work Shown:
x = weight of first ball
y = weight of second ball
each ball has a weight range of 0.31 kg to 0.37 kg, so,

add straight down to get

which simplifies to

the two soccer balls have a weight range of 0.62 to 0.74, inclusive of both endpoints.
--------
Without using algebra, you basically just add the smallest the two weights could be (0.31) to itself to get 0.31+0.31 = 0.62 which represents the smallest the two weights combined can be. The same happens with the largest weight of 0.37 to get 0.37+0.37 = 0.74 as the max weight of both objects together.
Answer:
a) 30
b) 2
at 2 seconds, the balloon reaches the greatest height, 30
Step-by-step explanation:
y=height
x=seconds
The greatest height that the table shows is 30; the number of seconds it took to reach 30 is 2, (2,30)
Accordingly:
at 2 seconds, the balloon reaches the greatest height, 30

Just read it carefully, it is worded weirdly, but just think about it.
Answer:
y = 44
Step-by-step explanation:
Well if y varies directly with x it means that when y increases x increase and if y decrease x also decreases.
So let us put this in a equation,
<em>y = kx
</em>
where 'k' is constant
so <em>k = y/x</em>
let us put the figures of x and y from given first statement;
x = 7 and y = 18
so, k = 18 / 7
which means, k = 2.57
lets put this value of k in the equation above,
we know from statement that, x = 17 and k = 2.57
so, y = 2.57 (17)
which means, y = 43.71
or we can round it off to, y = 44

Answer:
Answer:
1/2a^n
Step-by-step explanation:
Square of the monomial is
To get the monomial we take square root
Lets take square root for each term
because square root of 4 is 2
2/2 is 1 so, its a^n
Required monomial is
1/2a^n
