Answer:

11.725%

Step-by-step explanation:

Given that :

True value = 0.904 seconds

Measured time = 1.010 seconds

Experimental error :

(|measured value - True value | / true value) * 100%

(|1.010 - 0.904| ÷ 0.904) * 100%

= 0.106 / 0.904 * 100%

= 0.1172566 * 100%

= 11.725%

NEED HELP DUE IN 6 MINUTES!!!!
lesantik [10]

Answer:

120

Step-by-step explanation:

volume of triangular prism = area of base times length

the base is a triangle and the area of a triangle can be calculated by using this formula

a=\frac{bh}{2}

where b = base length and h = height

Dimensions of base

base length = 8cm and height = 3cm

Thus,

A=\frac{3*8}{2} \\3*8=24\\\frac{24}{2} =12\\

The length of the triangular prism is 10cm

Thus volume = 10 * 12 = 120

How does changing the scale change the distance represented?
QveST [7]

The <em>correct answer</em> is:

It does not.

Explanation:

The scale of a graph just tells us how many units are between numbers. This does not change the overall distance represented.

For example, I can have two graphs on which the x-axis goes to 60. On one graph, I can count by 10s for my scale, while the other graph uses 5s. While the scales are different, the same distance is represented.
