A student estimated a mass of 250grams, according to the scale the mass is actually 240grams. What is the percent error? (round

NeX [460]

Answer:

4.2%

Step-by-step explanation:

percent error = (estimated value - actual value)/(actual value) × 100%

Here, the estimated value is 250 g, and the actual value is 250 g.

percent error = (estimated value - actual value)/(actual value) × 100%

percent error = (250 g - 240 g)/(240 g) × 100%

percent error = 10/240 × 100%

percent error = 0.041666... × 100%

percent error = 4.2%

If he paints 1/2 of the wall blue, how many square feet will be blue?

ASHA 777 [7]

Answer:

70

Explanation:

Height of the wall = 8 2/5 ft

Height of the wall = 42/5 ft

The length of the wall = 16 2/3 ft

The length of the wall = 50/3 ft

The area of the wall = 42/5 x 50/3

The area of the wall = 14 x 10

The area of the wall = 140 square feet

Half of the wall was painted blue

Area of the wall painted blue = 140/2

Area of the wall painted blue = 70 square feet

How to convert nonlinear equation to linear equation?

9966 [12]

Let's take the non-linear equation:
${x}^{2} = \sqrt{3} y$
First Make The Equation To Be In Terms of Y

*Divide Both sides by
$\sqrt{3}$
$\frac{ {x}^{2} }{ \sqrt{3} } = \frac{ \sqrt{3} y}{ \sqrt{3} }$
*Simplify
$\frac{ {x}^{2} }{ \sqrt{3} } = y$
You shouldn't keep a radical in the denominator, however we leave it for the purpose of the reciprocal.

*Take The Reciprocal Of Both Sides
$\frac{ \sqrt{3} }{ {x}^{2} } = \frac{1}{y}$
A Linear Equation Takes The Format:
$y = mx + b$
So,
$\frac{1}{y} = y$
$b = 0$
$m(slope) = \frac{ \sqrt{3} }{x}$
$x = \frac{1}{x}$
Resulting in :
$\frac{1}{y} = \frac{ \sqrt{3} }{x} (\frac{1}{x} ) + 0$
