One log is 28 feet 7 inches long, and another is 39 feet 8 inches long. what is the sum of their length

1 answer:

3 0

1 foot is 12 inches

Convert everything to inches:
28 x 12 = 336 in.
39 x 12 = 468 in.

Add all the inches together:
336 + 468 + 7 + 8 = 819 in.

The answer is 819 inches.

Answer:

Change all of the number into the same form for ease of adding.

16.3 + 14.5 + 18.75 + 12.25 + 22.6 = 84.4

100 - 84.4 = 15.6

How many solutions doe

musickatia [10]

Answer:

Given equation have two solutions.

x = $-\frac{5}{2} and -\frac{8}{3}$

Right option is (D)

Step-by-step explanation:

We have given,

$6x^{2} +40=-31x$

we can rewrite this equation in the form given as:

6x² + 40 + 31x = 0

or 6x² + 31x + 40 = 0

On solving this quadratic equation, we get :

x = $-\frac{5}{2} and -\frac{8}{3}$

That means, given equation have two solutions.

Right option is (D)

For what value of x is sq 896z^15/225z^6 = xz^4/15

Ratling [72]

Answer:

Value of x is, 8

Step-by-step explanation:

Given: $\sqrt{\frac{896z^{15}}{225z^6}} =\frac{xz^4}{15} \sqrt{14z}$ ,.....[1]

To find the value of x:

Using exponent rules:

$(a^n)^m = a^{nm}$

$a^n \cdot a^m = a^{n+m}$

Taking square both sides in [1] we have;

$\frac{896z^{15}}{225z^6} = (\frac{xz^4}{15})^2 \cdot (14z)$

Simplify:

$\frac{896z^{15}}{225z^6} =\frac{x^2z^8}{225} \cdot (14z)$

$\frac{896z^{15}}{225z^6} =\frac{14x^2z^9}{225}$

Multiply both sides by $\frac{225}{14z^9}$ we get;

$x^2 = \frac{896 z^{15}}{225z^6} \times \frac{225}{14 z^9} = \frac{896 z^{15}}{14 z^{9+6}}$

Simplify:

$x^2 = \frac{896 z^{15}}{14 z^{15}} = 64$

$x = \sqrt{64}$

Simplify:

x = 8

Therefore, the value of x is, 8
