Answer:

  25 km/h

Step-by-step explanation:

The relation between speed, time, and distance is ...

  speed = distance/time

  distance = speed × time

__

The distance relation is used to find the distance on the first line of the table. The problem statement tells you all of the distances are the same.

The speed relation is used to find the speed on the remaining lines of the table. For the average speed, the total distance and total time are used in the computation.

The average speed is 25 km/h.

Answer:

4

Step-by-step explanation:

Arrange in order

1,1,2,3,4,4,5,7,8,9

Cross off each number from each side little by little

1,2,3,4,4,5,7,8

2,3,4,4,5,7

3,4,4,5

4,4

There are two numbers left so we would find whats between them. But, since it is the same number, you just write the same one as the median.

median= 4

Answer:

It is a rate,

A rate is the ratio between two related quantities in different units.

Miles and hours are two different units and its 50 miles per 2 hours.

Answer:

choice D) d ≥ 5

Step-by-step explanation:

Answer: 40 unit²

Step-by-step explanation:

A square pyramid is composed of 1 square and 4 congruent triangles

STEP ONE. Find the area of the square.

A=b²

b=base

A=b²=4²=14

STEP TWO. Find the area of the triangle

A=(1/2)bh

b=base

h=height

A=(1/2)bh

A=(1/2)(4)(3)

A=(1/2)(12)

A=6

There are 4 congruent triangles, so 6×4=24

The surface area of whole=24+16=40 unit²

Answer:

  x = 50

Step-by-step explanation:

The sum of exterior angles of a convex polygon is 360°.

  130° + x° + 30° + 100° + x° = 360°

  2x° = 100° . . . . . . . . . subtract 260° and collect terms

  x = 50 . . . . . . . . divide by 2°

_____

Additional comment

If you reduce each side length to nothing, then you find the angles are measured around a central point. It becomes more clear that their sum is 360°.

Explanation:

Imagine we have a point  

P

with Rectangular (also called Cartesian) coordinates  

(

x

,

y

)

and Polar coordinates  

(

r

,

θ

)

.

The following diagram will help us visualise the situation better:

https://keisan.casio.com/exec/system/1223526375

https://keisan.casio.com/exec/system/1223526375

We can see that a right triangle is formed with sides  

x

,  

y

and  

r

, as well as an angle  

θ

.

We have to find the relation between the Cartesian and Polar coordinates, respectively.

By Pythagora's theorem, we get the result

r

=

x

2

+

y

The only properties we can say about  

θ

are its trigonometric functions:

sin

y

/

r

⇒

y

=

r

sin

θ

cos

θ

=

x

/

r

⇒

So we have the following relations:

in the Rectangular system is equivalent to say

Answer:

  (a) 1.2b

  (b) 1.4h

  (c) A = 1.68bh

  (d) 68%

Step-by-step explanation:

(a) If 20% of b is added to b, you have ...

  b + 0.20b = 1.2b

__

(b) Similarly, if 40% of h is added to h, you have ...

  1.4h

__

(c) The area of the new rectangle is the product of the new dimensions:

  A = (1.2b)(1.4h)

  A = 1.68bh

__

(d) The original rectangle area is A = bh, so the percentage change can be computed as ...

  (A'/A -1)×100% = ((1.68bh)/(bh) -1)×100% = (1.68 -1)×100% = 68%

The given increases in base and height increase the area by 68%.

Answer:

? = 3×8/12 = 24/12 = 2

Step-by-step explanation:

Here it is, it is correct.

Answer: (2) /3

Step-by-step explanation:

#1 Way: Solve by a proportion

Let x be the unknown number

Given

8/12=x/3

Cross-multiply

12x=24

x=2

Ans: (2)/3

----------------------------------------------------------

#2 Way: Look at the product between numbers

Given

8/12=?/3

From this, we can see the difference (quotient) between the known value 3 and 12 is 4, meaning 12÷3=4.

Applying the same factor, 8÷4=2

Ans: (2)/3

Answer:

72°

Step-by-step explanation:

To convert from degrees to radians, multiply the degrees by [tex]\frac{\pi }{180}[/tex].

To convert from radians to degrees, multiply the radians by [tex]\frac{180}{\pi }[/tex].

Right now you're in radians, so multiply it by [tex]\frac{180}{\pi }[/tex].

[tex]\frac{12\pi }{5}* \frac{180}{\pi }[/tex]=[tex]432[/tex]°.

Now we need to find the reference angle for 432°.

If you draw 432° starting from the right and going clockwise (because it is a positive angle, if it was negative you would go counterclockwise), it will make one full rotation, which is 360°, and you will end up in the 1st quadrant, 72° past 360°.

Depending on the quadrant you land in, there might be different operations to perform. Please check the attached image.

In this case, we're in the 1st quadrant so we can leave the angle as is.

The answer is 72°.
