Answer:
96 people.
Step-by-step explanation:
Exponential equation for a decreasing amount:
The exponential equation for a decreasing amount is given by:
In which A(0) is the initial rate and r is the decay rate, as a decimal.
Currently, the number of people entering a shopping mall is 109.
This means that
It is estimated that the number of people entering the shopping mall will decrease by 3% each hour.
This means that
So
Find the total number of people entering the shopping mall at the end of 4 hours.
This is A(4). So
Rounding to the nearest whole number, 96 people.
Answer:
a). Lila collected 7/6 gallon in all.
b). She used for baking 5/12 gallon.
c) was left 1/3 gallon of honey
D) She used 3/8lb flour to make the brownies.
Step-by-step explanation:
a). Lila collected 7/6 gallon in all.
LCM=3*4=12
b). She used for baking 5/12 gallon.
She had 7/6 gallon of honey. She used 3/4 gallon for baking. To know how much honey was left, you have to substract 3/4 gallon from the total available honey 7/6 gallon.
You need to find LCM to substract fractions with different denominator:
LCM=12
c) was left 1/3 gallon of honey
To know how much honey was left you need to substract from the initial quantity of honey that is 3/4 gallon, the quantities used for baking, that are 1/6 gallon and 1/4 gallon.
Less common multiple: 12
We use LCM 12 to substract:
D) She used 3/8lb flour to make the brownies.
You know she used 1/2 lb flour to make the bread and to make cookies 1/8 more. So you need to do following math:
d)
She used 5/8 to make cookies and she used 1/4 more to make cookies than brownies, then you have to do following math;
