Question 1.

CAPEEPS IN MATH Climatologist Each year a tree is alive, it adds a layer of growth, called a tree ring, between its core and its bark. A climatologist measures the width of tree rings of a particular tree for different years:

The average temperature during the growing season is directly related to the width of the ring, with a greater width corresponding to a higher average temperature.

a. List the years in order of increasing ring width.

Answer:

Here. we want to order years based on va1ue given below, from least increase to greatest increase!

Firstly, we get all fractions to have common denominator which, in this case, will be 100.

Now, we compare numerators 53, 58, 56, 60, 65

Number 53 is less than 56 which is less than 58 which is less than 60 which is less than 65.

So, we can write them us:

35 < 56 < 58 < 60 < 65

Final thing to do ¡s to return numbers into given formats and write solution

\(\frac{53}{100}<\frac{14}{25}<\frac{29}{50}<\frac{3}{5}<\frac{13}{20}\)

Now, we want to write years corresponding to width of ring in increasing order:

1920, 1900, 1910, 1940, 1930

b. Which year was hottest? How do you know?

Answer:

Hottest year, by previous calculations was 1930

we can say that because we know that 1930, the width of ring was greatest!

c. Which year was coldest? How do you know?

Answer:

Coldest year, by previous calculations, was 1920

We can say that because we know that in 1920, the width of the ring was the least

Multiplication: You can do it by yourselves as an exercise!

**Unit 1 Review Answer Key Go Math Grade 6 Question 2.**

A parking garage has floors above and below ground level. For a scavenger hunt, Gaia’s friends are given a list of objects they need to find on the third and fourth level below ground, the first and fourth levels above ground, and ground level.

a. If ground level is 0 and the first level above ground is 1, which integers can you use to represent the other levels where objects are hidden? Explain your reasoning.

Answer:

As we know that the ground level is labeled as 0 and that the first level above ground is labeled as 1, we can conclude that the third level below ground is labeled as – 3,

fourth level below ground is Labeled as – 4 and the fourth level above ground is labeled as 4.

Our reasoning is quite simple here, we present levels below ground as negative integers, and levels above ground as positive integers

b. Graph the set of numbers on the number line.

Answer:

c. Gala wants to start at the lowest level and work her way up. List the levels in the order that Gala will search them.

Answer:

As we can see on the number line above, Gaia will have to search levels in order.

– 4, – 3, 0, 1, 4

Note that reading our number line from left to right allows us to order numbers from least to greatest.

d. If she takes the stairs, how many flights of stairs will she have to climb? How do you know?

Answer:

As we can see on the number line above, lowest level is 4

If she take the stairs, she will have to pass some levels that she won’t search.

If she starts at lowest level – 4, then she will have to climb 4 flights of stairs in order to get to ground Level 0.

Also, after she reaches 0 level she still has 4 flights of stairs to climb till fourth level above ground!

ALtogether, she has to climb:

4 + 4 = 8 flights of stairs!

We can also observe this using absolute value, as we are speaking about distance, 4 levels means 4 flights of stairs, so it doesn’t matter whether we are above/below ground, we are crossing same distance.

Explaination:

Given numbers are: – \(\frac{2}{3}\), –\(\frac{3}{4}\), 0.7, 0

Let’s order them from least to greatest!

The first thing is to transform them into equal form(decimals)!

– \(\frac{2}{3}\) = – 0.\(\dot{6}\)

– \(\frac{3}{4}\) = – 0.75

Now we can say that:

Number – 0.75 in less than – 0.\(\dot{6}\) which in less than 0 which is less than 0.7

Therefore, we can write the an:

– 0.75 < – 0.\(\dot{6}\) < 0 < 0.7

Now, we can return them into given forms and write them in the right order!

– \(\frac{3}{4}\), – \(\frac{2}{3}\), 0, 0.7

Question 11.

Which number line shows an integer and its opposite?

(A)

(B)

(C)

(D)

Answer:

(B)

Explaination:

Here, we could draw all 4 of given number tines, and conclude which one is correct!

However, there is no purpose to do so.

Let’s see what are we actually looking for, when finding our answer.

We want to find the one, which shows an integer and its opposite.

As by definition, the opposite of a number is the number on the other side of 0 number line, and the same distance from 0

So, we should have same distance from 0 on both sides!

There is only 1 graph that satisfies our terms.

It is:

Question 12.

Which is the greatest out of \(\frac{1}{3}\), – 1.2, 0.45, and – \(\frac{4}{5}\)?

Answer:

Given numbers are: \(\frac{1}{3}\), – \(\frac{4}{5}\), – 1.2. 0.45

Let’s order them from least to greatest, and then we will know our final solution!

First thing is to transform them into equal form(decimals)!

\(\frac{1}{3}\) = 0.3

– \(\frac{4}{5}\) = – 0.8

Now, we can say that:

Number – 1.2 is less than – 0.8 which is less than 0.\(\dot{3}\) which is less than 0.45.

Therefore, we can write them as:

– 1.2 < – 0.8 < 0.\(\dot{3}\) < 0.45

Now, if we take a look on previous expression, we can see that 0.45 is the greatest number among given ones!
