A submersible is a type of underwater vessel. Suppose a submersible starts at a depth of 40 feet below sea level, represented by –40 feet. The table shows the submersible's change in depth from one minute to the next.

Time and Depth of Submersible







2:15 p.m.

2:16 p.m.

2:17 p.m.

2:18 p.m.

–40 feet

180 feet lower

175 feet lower

185 feet lower

Answer the questions to find the depth of the submersible after 3 minutes.

Answer:

The total area of the back classroom wall is (20ft x 12ft) = 240ft²

The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².

Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.

Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

Answer: x=20

Step-by-step explanation:

3x+80=140

3x=60

x=20

Answer: Chris spent 60 tickets at the carnival.

Step-by-step explanation:

At the end of the night, both Chris and Keith had the same amount of tickets, so:

80 - x = 140 - 2x

Now, solve the equation. Start by bringing the -2x to the left side.

80 - x + 2x = 140

Bring the 80 to the right side so the variables are isolated.

-x + 2x = 60

Add like terms.

x = 60

Check the work.

Chris had 80, spent 60, so had 20 left. --> 80 - 60 = 20

Keith had 140, spent 120 (60 *2), so also had 20 left. --> 140 - 120 = 20

So, Chris spent 60 tickets at the carnival.

well, Yasin is correct, the exterior angles are all 36° each, however "g" is including more than just that, Check the picture below.

Answer: 36 is wrong

Step-by-step explanation: 360 - 36 = 324  degrees

Answer:

Students in 7th grade took a standardized math test that they also had taken in 5th grade. The results are shown on the dot plot, with the most recent data shown first.

Find and compare the means to the nearest tenth.

7th-grade mean:

✔ 16

5th-grade mean:

✔ 13.4

What is the relationship between the means?

✔ The 7th-grade mean is about 2.5  points higher.

Step-by-step explanation:

Mean for 7th Grade Students is: 16

Mean for 5th Grade Students is: 13.4

Comparing the means, the mean for 7th grade students is 2.6 higher than 5th grade students.

The mean is the average of the data set, that is the sum of each data value divided by the number of data points.

Given that, 7th Grade Students in 7th grade took a standardized math test that they also had taken in 5th grade.

Mean for 7th Grade Students:

Mean = [10 + 11 + (2 × 12) + 13 + 14 + (2 × 15) + (3 × 16) + (3 × 17) + (2 × 18) + (2 × 19) + (3 × 20)]/21

Mean = 335/21

Mean = 15.95 = 16

Mean for 5th Grade Students:

Mean = [8 + (2 × 9) + (2 × 10) + (2 × 11) + (2 × 12) + (2 × 13) + 14 + (3 × 15) + (2 × 16) + 17 (2 × 18) + 19

Mean = 281/21

Mean = 13.38 = 13.4

The difference between their means = 16 - 13.4 = 2.6.

Hence, Mean for 7th Grade Students is: 16

Mean for 5th Grade Students is: 13.4

Comparing the means, the mean for 7th grade students is 2.6 higher than 5th grade students.

11. -16

Step-by-step explanation:

Answer:

Altitude = 3

Step-by-step explanation:

Given the area of a triangle as 15, with a length of 10:

We can use the following formula for finding the area of a triangle:

Area (A) = ½bh  

Where:

Base (b) = 10

Height (h) or altitude = unknown

Substitute the given values into the formula:

Area (A) = ½bh  

15 = ½(10)h  

15 = 5h

Divide both sides by 5 to solve for h:

\(\displaystyle\mathsf{\frac{15}{5}\:=\:\frac{5h}{5} }\)

h = 3

Therefore, the length of the altitude or height of the given triangle is 3.

Answer: 16

Step-by-step explanation: First you take care of what's inside the parenthesis which is x+2 and sine x=2 you should get 4. Then you do have 4(4). Which means all you need to do is multiple 4 times 4 and you get 16.

Answer:

Solution

First identify the input values. The input value is the first coordinate in an ordered pair. There are no restrictions, as the ordered pairs are simply listed. The domain is the set of the first coordinates of the ordered pairs.

D={2,3,4,5,6}

Next identify the output values. The output value is the second coordinate in an ordered pair. The range is the set of the second coordinates of the ordered pairs. Do not list the same output twice.

The second coordinate in an ordered pair is the output value. The range is the collection of the ordered pairs' second coordinates. Never list the same output more than once.

The domain of the function is defined as the set of all the possible values of the function. A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

Determine the input values first. The first coordinate in an ordered pair makes up the input value. Since the ordered pairs are just listed, there are no restrictions. The set of the ordered pairs' initial coordinates is known as the domain.

D={2,3,4,5,6}

Next, identify the output values. The output value is the second coordinate in an ordered pair. The range is the set of the second coordinates of the ordered pairs. Do not list the same output twice.
