Answer:

Number 1: 3 hours.

Number 2: $2434.04

Step-by-step explanation:

3/4 + 3/4 = 1 1/2 (after some simplifying)

1 1/2 + 1 1/2=3. She practiced 3 hours.

Number 2 will be harder to explain. We have 3 sides. That means 90 1/4 x 3. That is 270 3/4. 270 x 8.99 (8.99 per foot) gets us 2427.3, 3/4 x 8.99 (rounded to nearest hundreths) gets us 6.74. We add that together, and we get $2434.04.

I am pretty sure about 1, although not so sure about 2. Hope that helps you.

You plan to begin your journey in San Jose and make stops in Denver and Chicago on your way to New York City. Your father says that your journey will be about 3,000 miles. Is this a close estimation of the distance? Explain your reasoning.

Answers

Answer:

"1 unit" is about 7.5 on the scale and the distance between Chicago and New York is about 10.8 on the scale.

Step-by-step explanation:

The scale factor on the map is 557.

What is scale factor?

When a shape is magnified and each side is multiplied by the same number, this is known as a scale factor. The scaling factor is this figure. Scale factors are used on maps to accurately depict distances between locations.

We have,

1 unit = 557 miles.

now, we have to find the scale factor,

i.e., the amount that must be multiplied by the map's unit of measurement to obtain the original distance between the two locations.

So, it means that the x unit = 557 x miles.

i.e. the scale factor = 557

Hence, The scale factor on the map is 557.

The mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.

What is mean absolute deviation?

It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance known as the MAD.

We have data as shown in the picture in the form of frequency graph.

The mean = 11/4 = 2.75

The difference between each value and mean is shown in the attached table.

MAD = 5/4 = 1.25

The nearest value is 1.1.

Thus, the mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.

Elena is trying to figure out how many movies she can download to her hard drive. The
hard drive is supposed to hold 500 gigabytes of data, but 58 gigabytes are already taken up
by other files. Each movie is 8 gigabytes. Elena wrote the inequality and
solved it to find the solution .

1. Explain how you know Elena made a mistake based on her solution.

2. Fix Elena’s inequality and explain what each part of the inequality means.

Answers

Answer: Elena used the "greater than" sign when she should have used the "less than sign".

The correct inequality is 8x + 58 < 500, where 8 is the amount of gigabytes taken up by a movie, x is the amount of movies, 58 is the amount of gigabytes already taken up, and 500 is the maximum storage capacity in gigabytes. The < sign denotes that 500 CANNOT be exceeded.

Step-by-step explanation:

Elena wrote the equation as 8x + 58 > 500, meaning that the amount of gigabytes MUST exceed 500. This does not make sense since a computer would still function even with less movies. Since the hard drive has a capacity of 500 GB, it cannot go higher, making the correct inequality 8x + 58 < 500.
