Hey go to attachments and help me out- thanks very much! this is my last question for today so it would really help also stay sa
Llana [10]

Answer:

A) 250 / 8 = 31.25

31.25 x 8 = 250 Know you know that one pancake requires 31.25ml of Milk

31.25 x 4 = 125

So 4 pancakes requires 125ml of Milk

B) 5 / 8 = 0.625

0.625 x 8 = 5 So just like last time, you know that 0.625g of butter is required to make 8 pancakes

0.625 x 12 = 7.5g of Butter

So 12 pancakes requires 7.5g of butter.

Hope this makes sense !

At the restaurant, your family orders a subtotal of $46.55. Add 6% sales tax and 18% tip. What is the total?
ICE Princess25 [194]

Answer:

Step-by-step explanation:

Now,

if you add the tip after the sales tax,

you will have:

46.55*(6/100)=2.79

the meal cost now 46.55+2.79=49.34

we add tip

49.34*(18/100)=8.88

total cost 49.34+8.88=58.22

Assume the mean useful life of a particular light bulb is 2,000 hours and is normally distributed with a standard deviation of 3
Yuri [45]
The mean = 2,000
s = Sigma ( standard deviation ) = 300
M - 2 s = 2,000- 2 * 300 = 2,000 - 600 = 1,400
M + 2 s = 2,000 + 2 * 300 = 2,000 + 600 = 2,600
Answer.
Useful life of light bulbs within 2 standard deviations of the mean is:
A ) Between 1,400 and 2,600 hours
