I’m not sure but I think u can just subtract 2-1,65 and than multiply by 100

Answer:

21%

Step-by-step explanation:

to find percent error you subtract the theoretical (actual) from the experimental, then divide by the theoretical; what you get is a decimal so if you multiply it by 100 you will get the percent

theoretical = 2.0 grams

experimental = 1.65 grams

(1.65 - 2.0) / 1.65 = -0.35/1.65 = -0.21

0.21 x 100 = 21 %

the scale has a 21% probability of being inaccurate

G(x)=3x+3<br> h(x)=-4x+<br> (g+h)(10)
lisabon 2012 [21]

Answer: (10x + 30)

Step-by-step explanation:

1. combine like terms. -4x + 3x = -x

2. you can’t have a negative x, so you would multiply the equation (-x+3) by -1, to get (x-3).

3. (x-3)(10)... 10 • x = 10x, 10 • 3 = 30.

4. put them together, answer would be 10x + 30.

The angle of elevation from a soccer ball on the ground to the top of the goal is 34. If the goal is 8 feet tall, What is the di
damaskus [11]

Answer:

The distance from he ball to the goal is 11.85 feet (Approx) .

Step-by-step explanation:

As given

The angle of elevation from a soccer ball on the ground to the top of the goal is 34° .

If the goal is 8 feet tall.

Now by using the trigonometric identity .

tan \theta = \frac{Perpendicular}{Base}

As shown in the diagram given below

\theta = 34^{\circ}

Perpendicular = AB = 8 feet

Base = BC

Put all the values in the identity .

tan\ 34^{\circ} = \frac{AB}{BC}

tan\ 34^{\circ} = \frac{8}{BC}

tan\ 34^{\circ} = 0.675\ (Approx)

BC = \frac{8}{0.675}

BC = 11.85 feet (Approx)

Therefore the distance from he ball to the goal is 11.85 feet (Approx) .
