David Howell was shopping for a leather jacket and found one on the dept. store that costs 395 dollars.
Now, he learned that an inflation rate of 4.5% has occurred since the jacket was originally priced.
=> 395 dollars * .045 = 17.775
=> 395 dollars - 17.775  = 377.23 is the original price of the jacket.

The table shows the number of cups of granola that a bakery uses for every 10 batches of energy bars.
timofeeve [1]

Answer:

<h2>Mike is correct.</h2><h3>To make 30 batches of Rasisin Nut energy bars, the bakery will use 84 cups of granola.</h3><h3>To make 15 batches of Honey Almond energy bars, the bakery will use 63 cups of granola.</h3>

Step-by-step explanation:

<em>Mike says that the bakery uses more granola to make 30 batches of Raisin Nut energy bars than to make 15 batches of Honey Almond energy bars.</em>

<em />

According to the table, the bakery uses 28 cups of granola for 10 batches of Raisin Nut, and 42 cups of granola for 10 batches of Honey Almond. Then, we multiply

R=28 \times 3 = 84 \ cups\\H=42 \times 1.5 = 63 \ cups

Therefore, the bakery uses more granola to make 30 batches of Raising, than to make 15 batches of Honey Almond. Mike is right.

<em>(Notice that we multiplied Raisin Nut by 3, because it represents 3 tens, and Honey Almond was multiplied by 1.5, which represents 15 batches)</em>

The life span of a battery is the amount of time the battery will last. The distribution of life span for a certain type of batt
slavikrds [6]

Answer:

0.0548

Step-by-step explanation:

The distribution of life span for a certain type of battery is approximately normal with mean 2.5 hours and standard deviation 0.25 hour.

To find the the probability that a selected battery will have a life span of at most 2.1 hours, we need to first determine the z-score for x=2.1 hours using

z =  \frac{x -  \mu}{ \sigma}

We substitute the values to get:

z =  \frac{2.1 - 2.5}{0.25}  =  - 1.6

We read read -1.6 from the standard normal distribution table to get:

P(X≤2.1)=0.0548

..1+4=5. 2+5=12. 3+6=21. 8+11=40 or this could be 96 which is right and why
andre [41]
Multiply the numbers being added then add the first number. 4X1=4, 4+1=5.
2X5=10, 10+2=12. 11X8=88, 88+8=96. I'm not sure how to get 40, though. 
Hope I could help.
