The baker has 42 kilograms of flour. She uses 8 kilograms each day.after how many days will she need to buy more flour?

5 days 6hours

Step-by-step explanation:

Given data

total amount of flour=42kg

number of kg used per day=8kg

Since we are expected to know when she will need more, we need to divide the total flour by the daily usage, to know when the flour we be exhausted

divide 42 by 8 we have

42/8=5.250.25 days to hours is 6hours

So it will take 5 days 6hours

15.32 m correct to 2 decimal places.

step-by-step explanation:

the distance c is the adjacent side to the 40 degree angle and the hypotenuse = 20 m. so :

cos 40 = adjacent side / hypotenuse = c / 20

c = 20 cos 40

= 15.32 m.
