Answer:

1.366km

Step-by-step explanation:

The height of the mountain is [tex]3.34Km[/tex]

A diagram of right angle triangle PBA is attached below which describe the situation as given in the question.

Let us consider that H represent the height of mountain.

Angle of elevation at point A and C shown in the diagram.

Apply tan function in triangle CBP.

            [tex]tan(35)=\frac{H}{x} \\\\H=xtan(35)=0.7x.........(1)[/tex]

Apply tan function in triangle ABP.

           [tex]tan(30)=\frac{H}{x+1}\\ \\(x+1)tan(30)=H\\\\(x+1)=\sqrt{3}H\\ \\x=\sqrt{3}H-1........(2)[/tex]

Substituting the value of equation 2 into equation 1.

      [tex]H=0.7(\sqrt{3}H-1)\\\\H=1.21H-0.7\\\\0.21H=0.7\\\\H=0.7/0.21=3.34Km[/tex]

Hence, The height of the mountain is [tex]3.34Km[/tex]

Answer:

t ≤ -135

Step-by-step explanation:

multiply each side by 5 which then cancels out the 5 in the fraction then turns -27 into -135. Since we multiplied negatives we flipped the sign.

Step-by-step explanation:

so pretty much y= is the line that goes up and it has its own numbers right. the x= is the line that goes at the bottom right right

Answer:

X actually equals 16 becaausw if yiu add 16+4 you get 20 and then you have to multiply 20 by 1 and you get 20 so x=16

Answer:

x = 16

I dont quite understand the x = 48 situation? But thats wrong if that's your answe

Step-by-step explanation:

So you have to find out what x is

in order to do that you have to work out the equation and whatever you do to one side you must do to the other side

simplify 1(x+4) = 20

x + 4 = 20

in order to get rid of 4 on one side you have to subtract it on both sides

so x = 16

Answer:

Multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.

Step-by-step explanation:

Let the first five multiples of ten be

10*1= 10

10*2= 20

10*3=30

10*4=40

10*5= 50

Suppose we chose 20 and 50.

Now multiplying 20 with 50 we get

20*50= 1000

IF we count the total number of zeros in the factors ( 20 and 50) they are 2.

But the number of zeros in the product (1000) are 3.

This is because when we multiply 2 with 5 we get 10 which adds to the existing number of zeros ( i.e 2) and we get a total of 3 zeros.

And multiplying 10 with 50 we get

10*50= 500

IF we count the total number of zeros in the factors ( 10 and 50) they are 2.

But the number of zeros in the product (500) are also 2.

This is because when we multiply 1 with 5 we get 5 which does not add to the existing number of zeros ( i.e 2) and the total number of zeros remain the same.

Similarly multiplying 20 with 30 we get

20*30= 600

IF we count the total number of zeros in the factors ( 20 and 30) they are 2.

But the number of zeros in the product (600) are also 2.

This is because when we multiply 2 with 3 we get 6 which does not have a zero and the total  number of zeros remain the same as in the factors.

So we see that multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.

Answer:

x = 24.571

Step-by-step explanation:

A circles angle is 360 degrees, so you can work out x by equalling everything to 360

360 = 5x + 12 + 9x + 4

360 = 14x + 16

360 - 16 = 344

344 = 14x

344 ÷ 14 = 24.571

x = 24.571

So the smaller angle is 225°

And the bigger angle is 135°

(I'm guessing shape isn't to scale)

Step-by-step explanation:

Given

[tex]x = cupcakes[/tex]

[tex]y = brownies[/tex]

From the first statement:

[tex]2.75x + 1.25y = 30[/tex]

From the second statement:

[tex]x + y \le 14[/tex]

Required

Solve graphically

I've written the equations (above) and they are:

[tex]x + y \le 14[/tex]

[tex]2.75x + 1.25y = 30[/tex]

See attachment for graph.

The blue line represents [tex]2.75x + 1.25y = 30[/tex]

The shaded part of the graph represents [tex]x + y \le 14[/tex]

From the graph, the solution is:

[tex]x = 8.5[/tex]

The unit circle is tricky, but here are some things to know:

              - To convert from radians to degrees, multiply by 180/π

              - To convert from degrees to radians, multiply by π/180

              -If the angle is negative, switch the signs of the axis above.

The information above is all you need to answer the above question, but if you want/need anything else on the unit circle, just let me know.
