Answer:

580 = 58 x 10

Step-by-step explanation:

When you multiply a number by 10, the product (or answer) is the factor (or number being multiplied) with a 0 at the end of it.
For example: 1 x 20 = 20 or 4,468 x 10 = 44,680
Therefore, 58 was multiplied by 10 to result in 580.
Since the question asks for an equation, you must use an equal sign ( = ) to show the relationship between the two numbers.
Hence, 580 = 58 x 10 or 58 x 10 = 580

The first system of equations has infinite solutions because you can write one equation as a linear combination of the other.The second system of equations has no solution because mathematically an incoherence results -14 = -2 / 7I attach the solutions for greater understanding.
x-4y=12; 5x-20y=60 --> infinitely many
y-7x=-14; 7y-49x=-2 --> none

A surveyor wishes to determine the height of a mountain. At a given position he measures the angle of elevation to the top as 43

Usimov [2.4K]

Answer:

4,486.93 ft

Step-by-step explanation:

Let 'h' be the height of the mountain and 'x' be the horizontal distance between the first position measured and the top of the mountain.

Two right triangles can be modeled such that their tangent relationships yield:

$tan(43.66) = \frac{h}{x}\\tan(38.2) = \frac{h}{x+1000}$

Solving the linear system:

$x= \frac{h}{tan(43.66)}\\x = \frac{h}{tan(38.2)} -1000\\\frac{h}{tan(43.66)}=\frac{h}{tan(38.2)} -1000\\1000 = 0.222869*h\\h=4,486.93\ ft$

The mountain is 4,486.93 ft high.

P = KT/V solve for k

IrinaK [193]

we have

$P=\frac{KT}{V}$

Solve for K means clear the variable K

so

Multiply both sides by $V$

$PV=V\frac{KT}{V}$

$PV=KT$

Divide both sides by $T$

$PV/T=KT/T$

$K=PV/T$

therefore

<u>the answer is</u>

$K=PV/T$
