7x2+1 is 15/2. 3x41+1 is 124/41
The LCF is 82 so you would multiply everything by 82
1230/2-10,168/41
615-248=367 I might be wrong tho

Answer:

-12.5%

Step-by-step explanation:

The percentage change in your time can be computed using ...

pct change = ((new value)/(old value) -1) × 100%

= (28/32 -1) × 100%

= (0.875 -1) × 100% = -12.5%

The time to finish level 2 decreased by 12.5%.

Answer:

$\displaystyle 36\:units$

Step-by-step explanation:

Split up this Isosceles, Right Triangle into two congruent smaller right triangles. The reflexive side [the line that splits them apart] is 6 units, and both legs are 8 units, leaving the hypotenuses to AUTOMATICALLY be 10 units, according to the Pythagorean Theorem:

$\displaystyle a^2 + b^2 = c^2 \\ \\ 6^2 + 8^2 = 10^2 \\ \\ 36 + 64 = 100 \\ \\ 100 = 100$
