Answer:
She uses 8.52 kgs of flour in 8 days
There are 6.48 kgs of flour left over after 8 days.
Step-by-step explanation:
First, you need to multiply 1.065 by 8 to get how much flour she uses in 8 days.
1.065 times 8 is 8.52. She uses 8.52 kgs of flour in 8 days.
Now, to get how much flour is left over after 8 days, you need to subtract 8.52 from 15 kgs.
15 - 8.52 = 6.48 kgs.

Answer:
9 boxes cost Rs 405
Step-by-step explanation:
1 box costs 45.
so, how much are 2 boxes ? what do you think ?
right, twice as much : 2 × 45 = 90
how much are 3 boxes ?
now it is three times the cost of 1 box : 3 × 45 = 135
do you see the pattern ?
it is really simple.
that is also the origin why we describe a multiplication by "times". we take a single item so and so many times.
when you see something like this, you know, they are talking about multiplication.
so, here we want to know how much 9 boxes cost.
therefore,
9 × 45 = 405
is the answer.

Answer:
19.92
Step-by-step explanation:
To overfill 5% of the time ;
The Zscore (value) to the left of (1 - 0.05) = 0.95 is 1.645
Using this Zscore value with the Zscore formula :
Zscore = (x - μ) / σ
σ = 0.05 ; x = 20 ounce
Substituting into the Zscore formula :
1.645 = (20 - μ) / 0.05
1.645*0.05 = 20 - μ
0.08225 = 20 - μ
μ = 20 - 0.08225
μ = 19.91775
μ = 19.92
