Answers:
a)
b) 0.299 s
Step-by-step explanation:
a) We are given the following equation:
If we divide by 2 both the numerator and the denominator, we will have:
b) From this equation:
is the reaction time in seconds
is the distance
is the acceleration due gravity
Solving:
This is the reaction time
Answer:
(a) = 71 cm
(b) = 89 cm
Step-by-step explanation:
(a.)
perimeter of a rectangular field = 324 m
length (l) = 91 m
width (w) = ?
Now,
<em>Perimeter Of Rectangle </em>
<u>= <em>P = 2(l + w)</em></u>
= 2(91 + w) = 324m
= 182 + 2w = 324m
= 2w = 324 - 182m
= 2w = 142m
= w = 142/2
= w = 71
(b.)
area of rectangular painting = 5696 cm²
width (w) = 64 cm
length (l) = ?
Now,
<em>Area Of Rectangle </em>
A = <em><u>l × </u></em><em><u>w</u></em>
= l × 64 = 5696
= l = 5696/64
= l = 89 cm
<h2>
<em><u>VERIFICATION</u></em><em><u>:</u></em><em><u>-</u></em></h2>
FOR (a)
= P = 2(l + w)
<em><u>= P = 2(91 + 71) = 324 cm</u></em>
FOR (b)
= l × w
A = 89 × 64 = 5696
Answer:
h = 196.7
Step-by-step explanation:
V = 1/3Bh
= 1/3(28)(h)
= 9.3h
1829.3333/9.3
h = 196.7
