The relevant log relation is ...

  log(a^b) = b·log(a)

__

This means your expression is equivalent to ...

  3·ln(5) = ln(5^3) = ln(125) ≈ 4.828314

Y=180°-70°=110°

Z=180°-y
=180°-110°
=70°

X=y
X=110°

Step-by-step explanation:

Solution,

∠IDJ = 70° ( being alternate angle in AB || CD )

∠ IDJ + x = 180° ( being co-interior angle in EF || GH )

or , 70° + x = 180°

or , x = 180° - 70°

x = 110°

Again,

∠BLH = ∠CKG ( Being alternate angle in AB || CD )

y = 110°

Finally ,

z + y = 180° ( Being adjacent supplementary angle )

or , z + 110° = 180°

z = 70°

Thus , x = 110 ° , y = 110 ° and z = 70°

A bird of species A, when diving, can travel six times as fast as a bird of species B top speed. If the total speeds for these
two birds is 259 miles per hour, find the fastest speed of the bird of species A and the fastest speed of the bird of species B.

What is the fastest speed of the bird species B in miles per hour and the fastest speed of the bird of species A in miles per hour

Answers

Answer:

37 mph, 222 mph

Step-by-step explanation:

Let the speed of bird of species A is x and speed of B is y.

The equations:

x + y = 259x = 6y

Substitute and solve for y:

6y + y = 2597y = 259y = 259/7y = 37

Find x:

x = 6*37 = 222

[tex]x[/tex]will be the speed of species b and [tex]4x[/tex] will be the speed of species a:

[tex]x + 4x = 180[/tex]

[tex]5x = 180[/tex]

[tex]x = \frac{180}{5}[/tex]

[tex]x = 36 \: m/h[/tex]

If species b has a speed of [tex]36 [/tex]m/h, the speed of species a is [tex]4[/tex]times that:

[tex]4 \times 36 = 144 m/h[/tex]

Answer :—

[tex]A = 36 \: m/h [/tex]

[tex]B = 144 \: m/h[/tex]

Ms. Jacobi writes the equation x+y=z. If x = 5, y = 3, and z = 53,
is the equation true? Explain your reasoning.

Answers

Answer:

no

Step-by-step explanation:

Because if we substitute the value of x,y and z we get

x+y=z

5+3=53(FALSE)

Answer and Step-by-step explanation:

No, this equation is not true. But in order to show this, we need to write out the equation. So if x = 5, and y = 3, then the equation for this equation would look like this:

5 + 3 = 8.

That is incorrect because 5 + 3 does not equal 53. This is a trick question that is trying to trick you. Now if that 5 was a 50, then this equation would be true.

So, 5 + 3 ≠ 53.

Determine whether the following statement is true or false.
The ordered pairs (8,- 9) and (-9,8) name the same point.

Answers

Hi!

I can help you with joy!

Are these ordered pairs the same? Do they name the same point?

(8, -9) and (-9,8) are our points.

The x-coordinate of one point is 8, and the x-coordinate of the second point is -9.

The y-coordinate of the first point is -9, and the y-coordinate of the second point is 8.

Thus, these 2 ordered pairs do not name the same point.

The statement is false.
