Just can decorate 2 full cakes. 6 divides by 3 is 2. So she decorated 2 per hour. If you do the work it’s 2 divided by 0.75 (3/4) you get 2 2/3. But that’s not a full 3 cakes so only 2. Glad to help!
The statement above is false, as a triangle with two congruent sides <em /><em></em>IS NOT ALWAYS a 45-45-90 triangle, however, it can be.
Hope this helps!
The acceleration is defined as the ratio between the change in velocity and the time elapsed to perform such a change.
These "changes" are indicated with the capital greek letter delta, 
, and when you write 
you mean the difference between the finial and the inital values of the variable x:
So, the acceleration is defined as
In this case, the initial velocity is 35, the final velocity is 65. Assuming we start the clock at the beginning of the observation, the inital time is 0 and the final time is 5. So, we have
m/s^2
To convert to scientific notation, start by moving the decimal place in the number until you have a coefficient between 1 and 10; here it is 3.45. The number of places to the left that you had to move the decimal point is the exponent. Here, we had to move the decimal 4 places to the right, so the exponent is -4.
2340000 = 2.34 x 10^6
0.000034= 3.4 x 10^-5
