timurjin [86]

Ht of ceiling = 10 ft which is two-thirds of living rm ceiling
Ht of living rm ceiling = 2/3x = 10 ft
2/3h = 10 ft
2/3h times 3/2 to solve for h = 10 times 3/2
h = 30/2
h = 15 ft

Please answer!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Ilya [14]

Answer:

The length of the hypotenuse is 26 inches

Step-by-step explanation:

The leg(brace) attached to the wall is 10 inches

Perpendicular = 10 inches

Your surfboard sits on a leg that is 24 inches.

Base = 24 inches

Formula : $Hypotenuse^2 = Perpendicular^2 +Base^2$

$Hypotenuse^2 = 10^2+24^2$

$Hypotenuse = \sqrt{10^2+24^2}$

Hypotenuse = 26

Hence the length of the hypotenuse is 26 inches

Solve for x. Evaluate and round your answer to 1 decimal place(tenths place). 10x=1200

Mandarinka [93]

Answer:

<h2>x = 3.1</h2>

Step-by-step explanation:

<h3> ${10}^{x} = 1200$ </h3>

<u>To solve first take logarithm to both sides</u>

That's

<h3> $log_{10}(10) ^{x} = log_{10}(1200)$ </h3><h3 /><h3> $log_{10}(10)^{x} = x log_{10}(10)$ </h3>

But

<h3> $log_{10}(10) = 1$ </h3>

So we have

$x = log_{10}(1200)$

<u>Write 1200 as a number with the factor 100</u>

That's

1200 = 100 × 12

So we have

<h3> $x = log_{10}(100 \times 12)$ </h3>

<u>Using the rules of logarithms</u>

That's

<h3> $log_{a}(x \times y) = log_{a}(x) + log_{a}(y)$ </h3>

Rewrite the expression

That's

<h3> $x = log_{10}(100) + log_{10}(12)$ </h3><h3 /><h3> $x = log_{10}(10)^{2} + log_{10}(12)$ </h3><h3> $x = 2 log_{10}(10) + log_{10}(12)$ </h3><h3> $log_{10}(10) = 1$ </h3><h3 /><h3> $x = 2 + log_{10}(12)$ </h3>

x = 3.079

So we have the final answer as

<h3>x = 3.1 to one decimal place</h3>
