Number 12 pleaseeeee
A,B,C, or D

Answer:

seems like the main concept being tested here is unit conversion.

First, let's look at converting kilometers to meters. In the metric system, the prefix "kilo" means 1000. So,

1 kilometer = 1000 meters.

Then, let's look at converting from hours to seconds. As you may know, there are 60 minutes in an hour, and 60 seconds in a minute. So, in 1 hour there are

1 hour*(60 minutes/hour)*(60 seconds/minute) = 3600 seconds.

So, we can use these unit conversion factors to solve your question. Let's convert the units!

9 km/hr = 9 km/hr * (1000 m/km) * (1 hr/ 3600 sec) = 2.5 m/s

Answer:

circumference = 97.34

Step-by-step explanation:

circumference = diameter x Pi

31 x 3.14 = 97.34 inches

The circumference of the circle with a diameter of 31 inches is approximately 97.34 inches.

The circumference of a circle can be calculated using the formula C = πd, where C represents the circumference and d represents the diameter of the circle.

Given that the diameter of the circle is 31 inches, we can substitute this value into the formula:

C = 3.14 * 31

C ≈ 97.34 inches

Therefore, the circumference of the circle with a diameter of 31 inches is approximately 97.34 inches.

Answer:

B. [tex]\frac{67}{10} x + 9[/tex]

Step-by-step explanation:

Simplify the expression. Remember to go by the order of operations, or PEMDAS.

1) First, distribute the numbers outside of the set of parentheses to the terms inside the set of parentheses next to them. Then, simplify the fractions.

[tex]3(\frac{7}{5} x + 4) -2 (\frac{3}{2} -\frac{5}{4} x)[/tex]

[tex]\frac{21}{5}x + 12 - \frac{6}{2} + \frac{10}{4} x[/tex]

[tex]\frac{21}{5} x + 12 - 3 + \frac{10}{4} x[/tex]

2) Finally, combine like terms. (This means to add or subtract constants and to add or subtract terms with the same variables.) You may need to convert terms to the same denominator in order to do so easier. Then, reduce the fraction.

[tex]\frac{21}{5} x + 9 + \frac{10}{4}x \\\frac{84}{20}x + \frac{50}{20}x + 9 \\\frac{134}{20}x + 9 \\\frac{67}{10}x + 9[/tex]

Thus, the answer is [tex]\frac{67}{10} x + 9[/tex].

Do not copy Faroquem9’s work I just used it to answer your question and also I just used it as a example and wrote it on my own way so don’t copy it use it as a example and write it on your own way or answer it on your own way

Answer:

A)2.9 is the value of "n".

Answer:

59

Step-by-step explanation:

The diagonals of an isosceles trapezoid are equal.

MO and NP are diagonals.  Therefore MO = NP

12y - 37 = 5y + 19

7y = 56

y = 8

MO = 12(8) - 37 = 96 - 37 = 59

NP = 5(8) + 19 = 40 + 19 = 59

7 units are the measurement of the segment NP.

In Mathematics, a polygon can be defined as a two-dimensional geometric figure that consists of straight line segments and a finite number of sides. Additionally, some examples of a polygon include the following:

• Triangle

• Quadrilateral

• Pentagon

• Hexagon

• Heptagon

• Octagon

• Nonagon

Generally speaking, the measure of the angle at the center of a regular polygon is equal to 360 degrees. Therefore, the smallest angle of rotation that maps (carries) a regular polygon onto itself can be calculated by using this formula:

α = 360/n

Since MNOP is an isosceles trapezoid, the non-parallel sides MN and OP have the same length. Therefore, we can set up an equation using the given lengths of the sides:

MP = NO

Substituting the given expressions for these lengths, we get:

16x - 13 = 9x + 8 + 5y + 19

Simplifying and rearranging terms, we get:

7x - 5y = 36 ........(1)

Similarly, we can set up another equation using the given lengths of the diagonals MO and PN:

MO + PN = MP + NO

Substituting the given expressions for these lengths, we get:

12y - 37 + 5y + 19 = 16x - 13 + 9x + 8

Simplifying and rearranging terms, we get:

17y - 16x = 42 ........(2)

Now, we have two equations (1) and (2) with two variables (x and y). Solving this system of equations, we get:

x = 7, y = 9

Substituting these values back into the given expressions for PN and NO, we get:

PN = 5y + 19 = 5(9) + 19 = 64

NO = 9x + 8 = 9(7) + 8 = 71

Therefore, the measure of segment NP is:

NP = NO - PN = 71 - 64 = 7

So, the measure of segment NP is 7 units.

Answer: 11

Step-by-step explanation:

i did 3.5 x 3.14 = 10.99 and rounded to the nearest whole number, 11.

The circumference of the circular window to the nearest whole number is 11 feet.

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is pir^2.

We have,

To find the circumference of the circular window, we need to use the formula:

C = πd

where C is the circumference, π is the constant pi, and d is the diameter of the circle.

Since the window is 3.5 feet across at its widest point, the diameter of the circle is also 3.5 feet.

Plugging in the value of the diameter in the formula, we get:

C = πd

C = 3.14 x 3.5

C = 10.99

Rounding the result to the nearest whole number, we get:

C ≈ 11 feet

Therefore,

The circumference of the circular window to the nearest whole number is 11 feet.

Answer:

1 1/8 inches.

Step-by-step explanation:

As the sails are similar,  corresponding sides are in the same ratio, so we have the equation

:24/3 = 9/b     where  b = base of the souvenir boat.

Cross multiply:

24b = 9*3

b = 27/24

= 1 1/8 inches.

Based on the shape of the souvenir and dimensions of boat, the base of the souvenir's sail is 1.125 inches

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

WE need to find the base of the souvenir sail.

Given that sail on the souvenir boat has the same shape as the sail on the sailboat. Which means that; they can be used to find each other's dimensions based on a scale factor.

The height of the sailboat = 24 feet.

The height of the souvenir boat's sail = 3 inches.

The scale is:

= 24 / 3

= 8

Then for every inch on the souvenir boat's sail, the sailboat is 8 feet.

The base of the souvenir boat sail;

= 9 / 8

= 1.125 inches

Hence, Based on the shape of the souvenir and dimensions of boat, the base of the souvenir's sail is 1.125 inches
