What do you remember about types of angles?

Answers

Answer 1

An acute angle is one that measures LESS than 90˚

An obtuse angle is one that measures between 90˚ and 180˚

A reflex angle is an angle that measures between 180˚ and 360˚

There are other many types of angles such as alternate angles and corresponding angles, but those 3 are the main ones.

The population, P, of Johnstown over a period of t years since the town
was founded can be estimated by P = 5,600e0.0591
In approximately how many years after the town's founding will the
population reach 11,200?

Answers

Answer:

12 years

Step-by-step explanation:

Given that

P = 5,600 e^0.0591

Reaching amount = 11,200

time period = t

We need to find out the time period i.e. t

So,

11,200 =  5,600 e^0.0591t

2 =  e^0.0591t

Now take the log on both the sides

ln2 = 0.0591t ln

t = ln2 ÷ 0.059

= 0.693147÷ 0.059

= 11.748

= 12 years

The scatter plot shows the relationship between the test scores of a group of students and the number of hours they study in a week.

Part A: What is the group of points labeled N called? What is the point labeled M called? Give a possible reason for the presence of point M.

Part B: Describe the association between students’ test scores and the number of hours they study.

Answers

Answer:

Step-by-step explanation:

m is called an outlier and it is a positive association

Answer:

Part A) Part N.) is called the cluster of the whole chart. Part M.) is called the outlier because it's not with the rest of the group, therefore, it's the outlier of the group.

Part B.)

The association between the students' test scores and the number of hours they've studied is a positive correlation. That means the longer the students spent time studying for their tests... the better grades they got because of it. It's a lot like a cause-and-effect kind of situation.

Amanda is pumping water into an aquarium at a rate of 12 liters per minute the aquarium had 42 liters of water in it before she started her goal is given by 13x+42<_234 where x is the number of minutes she pumps water into the aquarium

Answers

Answer:

Let x represent minutes.

The inequality derived from the question is...

58 > 18 + 5x

Solve for x...

58 > 18 + 5x

58 - 18 > 5x

40 > 5x

40/5 > x

8 > x

So it will take more than 8 minutes to have 58 liters.

If the base of a Pyramid has an area of 144sq ft And if the slant higher of the pyramid is 10ft what would be the higher of the pyramid

Answers

Answer:

the height of the pyramid is 8 ft

Step-by-step explanation:

Considering the base of the pyramid to be square whose area is 144 sq ft

This means the side of the base would be √144 = 12 ft.

Now, if you will imagine a pyramid we can easily observe that

Height(H) , slant height( L=10 ft) and half of the side length( 6ft) make a right angle triangle. We can easily calculate height from Pythagoras theorem as

10^2 = H^2 +6^2

⇒ H^2 = 10^2-6^2 = 100-36 = 64

⇒ H = 8 ft

Therefore, the height of the pyramid is 8 ft

The total number of counters is 18.

6 of those are red so there would be 6/18 red counters

Simplified, that is 1/3

a. 1/3

Red counters (6) + Green counters (8)=14

14/18 aren’t blue

b. 14/18
Answer:
A - 6/18 reduced to 1/3
B - 14/18 reduced to 7/9


Explanation:
A - Add up all the numbers as the denominator (bottom) of your ratio fraction. Then take the number of red counters as the numerator (top) to place on top. You then get 6/18. Both numbers can be divided by 6 to get 1/3.

B - Add up all the numbers as the denominator (bottom) like you did above. Then subtract the total number by the number of blue counters (4). That number is 14 because the total number is 18 and it is your numerator (top). Now you have 14/18 which can both be divided by 2 to get 7/9.

Hope this helps, have a great day :)
