Yohan Blake ran the 100-meter race in the 2012 Olympics in 9.75 seconds. Compare the speeds if he ran the 200-meter race in 19.5

Pavel [41]

Answer:

The speeds are equal.

Step-by-step explanation:

<em>100 meters in 9.75 seconds</em> compared to <em>200 meters in 19.5 seconds</em>.

(100 m)/(9.75 s) = 10.2564 m/s

(200 m)/(19.5 s) = 10.2564 m/s

The speeds are equal.

How to solve this please I really need it now

Aneli [31]

Answer:

x=11

Step-by-step explanation:

the question would be to find x

3x + 28 + 5x + 52 + 2x - 10=180 (sum of angles in a triangle is equal to 180⁰)

10x + 70=180

10x=180-70

10x=110

x=110/10

x=11

I need help on this assignment

JulsSmile [24]

Given:

A figure of a rectangular prism with length l, width w and height h.

To find:

The surface area of the rectangular prism.

Solution:

The product of twice of the length l and the width w is:

$2\times l\times w=2lw$ ...(i)

The product of twice of the length l and the height is:

$2\times l\times h=2lh$ ...(ii)

The product of twice of the width w and the height h is:

$2\times w\times h=2wh$ ...(iii)

The surface area of the prism is the sum of (i), (ii) and (iii). So, the expression for the surface area is:

$A=2lw+2lh+2wh$

$A=2(lw+lh+wh)$

Therefore, the required expression is $2(lw+lh+wh)$ .
