Given: Side lengths of a right triangle 3,4 and 5 units.

To draw: A right triangle with the given side length.

Solution:

We know, in a right angle triangle hypotenuse is the longest side and satisfying Pythagoras theorem.

From the given side length,

Hypotenuse = 5 unit

We can take any of the base and perpendicular.

Let, Base = 3 unit

Perpendicular = 4 unit.

It a right-angle triangle with a hypotenuse 5 unit.

Now we draw a right angle triangle taking in the first 3 base and 4 perpendicular and second 3 perpendicular and 4 bases.

Answer:

$12.31

Step-by-step explanation:

Think of the original rate of pay as being 100%.

If your rate is increasing by 7%, it will now be 107% of the original rate (since 100% + 7% = 107%)

To find 107% of $11.50, convert 107% into a decimal

⇒ 107% = 107/100 = 1.07

then multiply this by the original rate to get the new increased rate:

⇒ $11.50 × 1.07 = $12.305

Rounding this to the nearest hundred = $12.31

Alternatively, you can find 7% of $11.50 and then add this to $11.50.

⇒ 7% = 7/100 = 0.07

Therefore, 7% of $11.50 = 0.07 × $11.50 = $0.805

Add this to the original rate:

$11.50 + $0.805 = $12.305

Rounding this to the nearest hundred = $12.31

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

To determine the scale factor used to dilate polygon ABCD to A′B′C′D′, we can compare the corresponding side lengths.

The distance between A(1, 1) and B(3, 1) is 2 units, and the distance between A′(3, 3) and B′(9, 3) is 6 units, so the horizontal side has been scaled by a factor of 6/2 = 3.

Similarly, the distance between A(1, 1) and D(1, 2) is 1 unit, and the distance between A′(3, 3) and D′(3, 6) is 3 units, so the vertical side has been scaled by a factor of 3/1 = 3.

Since both scaling factors are equal to 3, the overall scale factor used to dilate the polygon is 3. Answer: 3.

Let’s mark the Triangle Points as Point A, Point B, Point C.

Point A = 1x°

Point B = 2x°

Point C = 3x°

We know that the Angle Sum of a Triangle is equal to 180°.

So, Point A + Point B +Point C = 180°

   = 1x° + 2x° + 3x° = 180°

   = (1 + 2 + 3)x° = 180°

   = 6x° = 180°

   = x° = (180/6)°

   = x° = 30°

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

Answer:

-3/1 is the correct answer

Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20  + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33  

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

Answer:

\(x=20^o\)

Step-by-step explanation:

from the diagram, we can define the remaining angle in the quadrilateral through the sum of angles in any quadrilateral, which is \(360^o\), so the remaining unknown angle should be:

\(360-(50+2x+x)=310-3x\)

now that we have the unknown angle, we can find x through the point at which the outer angle is. \(x+90\) degrees. (sum of angles at one point is 360 degrees)

\(310-3x +x+90=360\\\\400-2x=360\\2x=400-360\\x=20^o\)

The value of variable x is,

x = 20

We have to given that,

In the diagram below, all angles are given in degrees.

Since, the sum of angles in any quadrilateral is, 360 degree.

Let measure of fourth angle is, y

Hence, We get;

(50 + 2x + y + x ) = 360

50 + 3x + y = 360

3x + y  = 360 - 50

3x + y = 310

y = 310 - 3x

Now, We get;

(310 - 3x) + (x + 90) = 360

Solve for x,

310 - 3x + x + 90 = 360

400 - 2x = 360

400 - 360 = 2x

2x = 40

x = 40/2

x = 20

Therefore, The solution is, 20

Answer:

The rate of change in elevation for the second scuba diver is -82 feet per minute.

Step-by-step explanation:

-123 feet every minute.

1.5x more than 2nd diver.

-123/1.5 = 2nd diver rate

2nd diver rate = -82

The rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.

Given that, a scuba diver's elevation changed by -123 feet every minute.

When something has a constant rate of change, one quantity changes in relation to the other. For example, for every half  hour the pigeon flies, he can cover a distance of 25 miles. We can write this constant rate as a ratio. For ratios, it's always a good idea to state both units in whole terms.

1½=1.5 times the rate of change for a second scuba diver

Now, rate of change in elevation of the second scuba diver

= -123/1.5

= -82 feet per second

Hence, the rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.
