Answer:

B .62.5 m

Step-by-step explanation:

convert Kmh-1 in to ms-1

30 Kmh-1 = (30×1000) ÷3600 = 8.3ms-1

60 Kmh-1 = (60×1000) ÷3600 = 16.6 ms-1

acceleration = (16.6 - 8.3) ÷ 5 = 1.66 ms-2

V^2 = U^2 +2aS

(16.6)^2 = (8.3)^2 + 2×1.66 ×S

S = 62.5 m

The length of a rectangle is 17 m and the width is 12 m what is the perimeter of the rectangle
lbvjy [14]

Answer:

<h2>The answer is 58 m</h2>

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

length = 17 m

width = 12 m

Substitute the values into the above formula and solve for the perimeter

We have

Perimeter = 2(17) + 2(12)

= 34 + 24

We have the final answer as

<h3>58 m</h3>

Hope this helps you

PLEASE HELP and explain! ill give brainliest if you do
EastWind [94]

Area of the rectangle

= l  \times b

= 8 \times 6

= 48 {in}^{2}

Area of the semicircles

= 2 \times ( \frac{1}{2} \pi {r}^{2} )

= \pi {r}^{2}

= \pi {3}^{2}

= 9\pi

= 9 \times 3.14

= 28.26 {in}^{2}

Area of the figure

= 48 + 28.26

= 76.26 {in}^{2}

= 76.3in²
