0.1 million years is equal to 100,000 years.
25,000 is smaller than 100,000 years.

You need to buy some chicken for dinner tonight. You found an ad showing that the store across town has it on sale for $2.79 a p

Ann [662]

Answer:

Store across town saves $0.69 but takes 26 extra minutes of driving.

Step-by-step explanation:

The relevant information is in bold below.

How much chicken will you be buying? 4 pounds

How much far are the two stores? My neighborhood store is 2.2 miles away, and takes about 8 minutes. The store across town is 8.3 miles away, and takes about 22 minutes.

How kind of mileage does your car get? It averages about 25 miles per gallon in the city.

How many gallons does your car hold? About 15 gallons

How much is gas? About $3.72/gallon right now.

To answer this question, we need to factor in the price of the chicken at each store and the price of the gas to drive to each store.

For each situation, multiply the cost per lb of chicken by 4 lb to get the price of the chicken. Then divide miles by miles per gal to get number of gallons needed. Multiply number of gallons needed by cost of gas to find price of gas.

1. Neighborhood store:

Chicken price: $3.19/lb * 4 lb = $12.76

Gas price: (2.2 miles)/(25 miles/gal) * $3.72/gal = $0.33

Total cost (chicken and gas) = $12.76 + $0.33 = $13.09

2. Store across town:

Chicken price: $2.79/lb * 4 lb = $11.16

Gas price: (8.3 miles)/(25 miles/gal) * $3.72/gal = $1.24

Total cost (chicken and gas) = $11.16 + $1.24 = $12.40

Answer: If the only consideration is money, then it is cheaper to buy in the store across town. You will save $13.09 - $12.40 = $0.69

If driving plays a part in the decision, then it takes 44 minutes round trip to the store across town and only 16 minutes for the neighborhood store. The difference is 26 minutes. Is saving $0.69 worth an extra 26 minutes of driving?

Professor Ivy has following scores on her final exams: 97 88 66 55 89 72 94 32 84 89 72 76 77 Express answers rounded correctly

Gre4nikov [31]

Answer:

The rest of the question:

Find Mean, Median, Mode, 25th Percentile, 75th Percentile, Maximum, Minimum, Range and IQR.

Let's begin by placing the data points in order from least to greatest:

32 55 66 72 72 76 77 84 88 89 89 94 97

n = 13

1) Mean sometimes called the average = the sum of the data over its number

Mean =( 32+55+66+72+72+76+77+84+88+89+89+94+97 )/13 =

= 991/13 = 76.23 ≈ 76.2 (to the nearest tenth)

2) Median is the middle data point = 77

3) Mode is any number within a set that occurs the most often

Mode = 72 and 89

We will making a data in suitable form to find the remaining requirements:

(32 55 66 72 72 76) 77 (84 88 89 89 94 97)

4) 25th Percentile = Quartile 1 (Q1) which is the median of the first set of data

∴ 25th Percentile = (66+72)/2 = 138/2 = 69

5) 75th Percentile= Quartile 3 (Q3) which is the median of the second set of data

∴ 75th Percentile = (89+89)/2 = 89

6) Maximum = 97

7) Minimum = 32

8) Range = Maximum - Minimum = 97 - 32 = 65

9) IQR (interquartile range) = Q3 - Q1 = 89 - 69 = 20

Find two consecutive even integers such that the square of the second, decreased by twice the first is 52

Fiesta28 [93]

Let the first integer be $x$ . So, the next even number is $x+2$

Let's translate the formula: the square of the second is $(x+2)^2$ , twice the first is $2x$ . So, the equation is

$(x+2)^2 - 2x = 52$

Expand the square to get

$x^2+4x+4-2x = 52 \iff x^2+2x+4 = 52 \iff x^2+2x - 48 = 0$

The solutions to this equations are

$x = -8,\quad x = 6$

So, the possible consecutive even numbers are

$-8\text{ and } -6\quad\text{or}\quad 6\text{ and } 8$

Estimate each product. 2/3×26

kondor19780726 [428]

If i understand the question.
you are estimating up each number.
so it would be 2/3 going into 1 and 26 going into 30
both turning into whole numbers.
