Answer:
If y = 105, x should be 15: x =15
Step-by-step explanation:
26 and 2/10 is how to write the answer as a mixed number fraction.
To express the sum of two numbers using distributive property, we factor out the highest common factor (HCF) of the two numbers (i.e. the greatest number that can divide the two numbers without remainder)
28 = 2 x 2 x 7
42 = 2 x 3 x 7
The HCF of 28 and 42 is given by 2 x 7 = 14
Therefore, we express 28 + 42 using distributive property thus: 14(2 + 3)
9, 16, __, 36, 49, ___
16 - 9 = 7
49 - 36 = 13
13 - 7 = 6
6 + 7 = 13
So we will add 7.
16 + 7 = 23
49 + 7 = 56
SO, 9, 16, 23, 36, 49, 56

Answer:
The error that might occur is 
Step-by-step explanation:
Given



Required
Determine the error that might occur in the volume of the tumor
Given that there's an error in measurement, this question will be solved using the concept of differentiation;
First, we'll rewrite the given parameters in differentiation notations;
--- Radius
--- Change in measurement
--- Volume as a function of radius
The relationship between the above parameters is as follows;

This can be rewritten as

Substitute
for 

Multiply both sides by dr



Differentiate



Substitute the values of r, dr and take
as 3.142


<em>(Approximated)</em>
Hence, the error that might occur is ±0.123
