Answer:
c
Step-by-step explanation:
because I had a test on these
We first calculate Pablo's height .
4 = 100%
x = 1% (Where x is 1% of Sandra's height.)
cross multiplying the equation, we get:
100x = 4 → x = 4/100 → x = 0.04
If 1% = 0.04, then 10% will be 0.04 × 10 = 0.4
Pablo's height is 4 + 0.4 = 4.4 feet.
Now we repeat the above steps to get Michal's height from Pablo's height
4.4 = 100%
x = 1% so:
100x = 4.4 → x = 4.4/ 100 → x = 0.044
If 1% = 0.044, then 8% will be 0.044 × 8 = 0.35
Michael's height is 4.4 + 0.35 = 4.75 feet.
13 1/3 bags.
We start off with:
8 x 1 2/3
Convert the mixed number into an improper fraction:
8 x 5/3
Multiply:
40/3
Simplify:
13.333...
Convert decimal to fraction:
13 1/3
