21^2 + 28^2 = Hypotenuse^2
441 + 784 = 1225
sqrt (1225) = 35
hypotenuse = 35

See explanation
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.
<span>set x = length, then x-14 would be width,
perimeter would be 2(x) + 2(x-14) = 96,
simplify this, u get 2x + 2x - 28 = 96,
you then get 4x = 124, now we know x = 31,
you would then be 31-14 which is 17.
so length is 31 m and width is 17 m</span>

Step-by-step explanation:
if it is on sale for 40 percent off, then it would be 60 percent of the original price. 18/6=3. 3*4=12. 3*6=18. 12 + 18 = 30
