Step-by-step explanation:
Represent Mathew with M and Joe with J
The question has missing details as diameter found by Joe is missing.
However, we'll assume a value for this.
Let
J = 1440mm
This implies that
M = 102* J
Substitute 1440mm for J
So:
M = 102 * 1440mm
M = 14280mm
The question say the answer must be in standard form.
The form is written as:
a * 10^n
Where 1 ≤ a ≤ 9 and n is an integer
So,
M = 14280mm becomes
M = 1.4280 * 10⁴mm
M = 1.43 * 10⁴mm (approximated)
So, all you need to do is replace actual measurements of Joe's diameter with 1440m.
Other steps remain the same.
