To do the scientific notation you would:
Multiply the coefficients and then round the number of significant figures into the coefficient with the smaller number.
Then you would add your exponents
And then your result is converted into the scientific notation.
Hope this helps! :3
A. first total salary (S) is what is being found so put that on one side of the equal side, then 100 dollars are being made and this is not changed so we don't need a variable, put that on the other side of the equal sign. and since sales (X) is changing, keep the variable, 30% of that is added to the salary, so multiply that by x (first turn it into a decimal, divide it by 100) and add that to the initial 100
S=100+.3X
B. do the same thing above but with a new decimal and initial salary
S=150+.15X
C. since they both need to be equal (S=S) you can replace the S on one equation with the other
100+.3X=150+.15X
Answer:
7 quarters are spent for throwing 350 food pebbles in pond.
Step-by-step explanation:
Given:
Reggie receives 50 food pebbles for every quarter he spends.
Number of food pebbles he has = 350
Let the number of quarters spent for 350 pebbles be 'x'.
Now, using proportion and cross multiplication method, we can find 'x'.
<u><em>1 quarter is equivalent to 50 pebbles thrown in pond.</em></u>
<u><em>So, 'x' quarters is equivalent to 350 pebbles thrown in pond.</em></u>
So, 7 quarters are spent for throwing 350 food pebbles in pond.
50 miles or 20 yards but it doesn't matter
