ASAP PLEASE HELP An ostrich egg has a mass of 1.2 kg to the nearest tenth of a kilogram. Find the minimum and maximum possible m
katen-ka-za [31]

The maximum possible measurement is 1.25 Kg and the minimum possible measurement is 1.15 kg

<u>Solution:</u>

Given mass of an ostrich egg is 1.2 Kg

We have to find the minimum and maximum possible measurements to the nearest tenth of a kilogram

The greatest possible error in measurement nearest tenth of a kilogram, is a half a tenth of a kilogram which is:-

\frac{1}{2} \times \frac{1}{10}=\frac{1}{20}

Now, the maximum value will be equal to calculated amount plus the error in measurement of value .i.e.

\text { Maximum value }=1.2+\frac{1}{20}=1.2+0.05=1.25

Now, the minimum value will be equal to calculated amount minus  the error in measurement of value .i.e.

\text { Minimum value }=1.2-\frac{1}{20}=1.2-0.05=1.15

Hence, maximum possible measurement is 1.25 Kg

And the minimum possible measurement is 1.15 kg

I'm taking a special math class to help in prove in a few areas before the real stuff begins. Heres the question.
Alekssandra [29.7K]
Whole numbers are numbers that are not fractions and do not include negative numbers
an example is
0,1,2,3,4,5,....

so let's see if any numbers make the statements fale
y is z less than x
y=-z+x
does this equal y+x=z?
y=-z+x
add z
y+z=x
subtract y
z=-y+x
not equal to z=y+x
so first is not the answer

y is z more than x
y=z+x
subtract x
y-x=z
not equal to z=y+x
so secod is not answer either


x is y less than z
x=-y+z
add y
x+y=z
this is equal to x+y=z to this is correct

xis y more than z
x=y+z
subtract y
x-y=z
this is not equal to x+y=z

therefor the answer is x is y less than z
