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:
answer is B
Step-by-step explanation:
as S and T are points on the same line
Answer:
Answer is 27, 32, 45
Step-by-step explanation:
In the right angle triangle, hypontenous is the longest side.
∴ In each option square of longest side has to be equal to the sum of square of other two side.
We know,
( as per pythogorean theorem)
If we check the last option; 27, 32, 45
In the given set of integer, we have longest side as 45
∴ conisdering 45 as hyptenous
Subtituting the value in the formula
⇒
⇒
⇒
∴ 
Hence, the set of given integer is not a pythagorean triple and are not side length of right angle.
Answer:
Choice A, C and E
Step-by-step explanation:
<em>Your table is poorly presented</em>
Given
x y

First, we calculate the constant of proportionality (k)

For (3,1.47)


For (5,2.45)


For (9,4.41)


From the above calculations, the constant of proportionality is 0.49.
So, the usable rows must also have 0.49 as their constant of proportionality
<u>Choice A</u>


--- <em>This is usable</em>

<u>Choice B</u>


--- <em>This is not usable</em>

<u>Choice D</u>


---- <em>This is not usable</em>
