Answer:

B = 42°

Step-by-step explanation:

hope it help

plz fo"ow me

The measure of the angle B when angle A and angle b is complementary angle should be 42 degrees.

Since

Angle A and Angle B are complementary. And, angle A is 48°.

We know that

The sum of complementary angles is 90 degrees

So it can be like

A + B = 90

48  + B = 90

B = 90 - 48

= 42 degrees

hence, The measure of the angle B when angle A and angle b is complementary angle should be 42 degrees.

Answer:

147.7 meters

Step-by-step explanation:

kilo means 'thousands' so you have to move the demical 3 places to the left to make .1477 a thousand times larger

also, you could set up a proportion like the following based on 1km = 1000m

1000 m =  x  

   1 km        .1477

x = .1477 x 1000

x = 147.7

Answer:

Answer:

D)     x =3  and x =7

Step-by-step explanation:

Step(i):-

Given function f(x) = 2x -2

                       g(x) = x² - 8x +19

Given that f(x) = g(x)

       ⇒  2x -2 = x² - 8x +19

      ⇒ x² - 8x +19 -2x +2 =0

   ⇒   x² -10x +21 =0

Step(ii):-

The factors are  x² -10x +21 =0

  ⇒  x² - 7x - 3x +21 =0

 ⇒ x( x-7) -3( x-7) =0

⇒ (x-3)(x-7) =0

    x =3  and x =7

Step-by-step explanation:

Maybe you want to know the number of each kind of animal.

__

We can write two equations in the two unknowns.

  p + c = 14 . . . . . . number of animals

  4p +2c = 44 . . .  number of legs

Dividing the second equation by 2, it becomes ...

  2p +c = 22

Then subtracting the first equation gives ...

  (2p +c) -(p +c) = (22) -(14)

  p = 8

  8 +c = 14

  c = 6

Answer:

the distance between two opposite corners of the intersection is 8.60 meters

Step-by-step explanation:

The computation of the distance between two opposite corners of the intersection is given below:

Here we applied the Pythagoras theorem

[tex]= \sqrt{7^2 + 5^2} \\\\= \sqrt{49 + 25} \\\\= \sqrt{74}[/tex]

= 8.60 meters

hence, the distance between two opposite corners of the intersection is 8.60 meters

Just follow this formula.

Area of a Circle= [tex]\pi R^{2}[/tex]

That means PI Radius Squared

Answer:

x = -3.5

Step-by-step explanation:

POE = PROPERTY OF EQUALITY

3*2 + 2x + 1 = 0

6 + 2x + 1 = 0 ## ^ Multiplication

7 + 2x = 0 ## ^ Combine like-terms

2x = -7 ## ^ Subtraction POE

x = -3.5 ## ^ Division POE

Answer:

X=0

Step-by-step explanation:

Use PEMDAS to get rid of some things. Do 3 x 2 = 6. Then distribute the like terms to one side seperating 2x and "0": +1 ---> 0-1 = -1. Now divide... 2x/2 = x (cancels out) and 0/2 = 0. Therefore X=0. But I'm not a computer so double check your answer.

Answer:

m = 11, and the correct equation is m + 7.28 = 18.28

Step-by-step explanation:

First, we need to solve:

0.2*m = 2.20

To do it, we need to divide by 0.2 in both sides:

0.2*m/0.2 = 2.20/0.2

m*(0.2/0.2) = 11

m = 11

Ok, we know the value of m.

Now we need to input the value of m in each one of these 4 equations and see which one is the correct one.

The correct equation is;

m + 7.28 = 18.28

When we replace m by 11, we get:

11 + 7.28 = 18.28

So the equation is correct.

Step-by-step explanation:

Answer: The train traveled 199.5 km

Step-by-step explanation:

We know the relationship:

Distance = Time*Speed

We know that the speed of the train was 105km/h

And we know that it leaves at 13:14, and arrives at 15:08.

Then the total amount of time that the train was traveling is:

T = (15 hours and 8 mins) - (13 hours and 14 mins)

= (15 - 13) hours and (8 - 14) mins

=  2 hours and (-6) mins.

We know that one hour has 60 minutes, then this is equal to:

T = 1 hour and 54 minutes.

But because the speed is kilometers per hour, we need to rewrite the 54 minutes in hours.

This can be done as follows:

1 hour = 60 minutes.

Then: 54 minutes = (54/60) hours = 0.9 hours.

Then:

1 hour and 54 minutes = 1.9 hours.

Now we know the speed and the time, then the distance can be calculated as:

Distance = speed*time = 105km/h*(1.9 h) = 199.5 km

The train traveled 199.5 km

Answer:

The train traveled 199.5 km

Step-by-step explanation:

We know the relationship:

Distance = Time*Speed

We know that the speed of the train was 105km/h

And we know that it leaves at 13:14, and arrives at 15:08.

Then the total amount of time that the train was traveling is:

T = (15 hours and 8 mins) - (13 hours and 14 mins)

= (15 - 13) hours and (8 - 14) mins

=  2 hours and (-6) mins.

We know that one hour has 60 minutes, then this is equal to:

T = 1 hour and 54 minutes.

But because the speed is kilometers per hour, we need to rewrite the 54 minutes in hours.

This can be done as follows:

1 hour = 60 minutes.

Then: 54 minutes = (54/60) hours = 0.9 hours.

Then:

1 hour and 54 minutes = 1.9 hours.

Now we know the speed and the time, then the distance can be calculated as:

Distance = speed*time = 105km/h*(1.9 h) = 199.5 km

The train traveled 199.5 km

Answer:

the length and width be 15 meters and 7 meters respectively

Step-by-step explanation:

The computation of the dimension of the field is given below;

Let us assume the fencing be p

Length be x

And, the width be x - 8

So,

P = 44

P = x - 8 + x - 8 + x + x

= 4x - 16

Now

4x - 16 = 44

4x = 44 + 16

4x = 60

x = 15

And, the width be 15 - 8 = 7

So, the length and width be 15 meters and 7 meters respectively
