Answer:
Significant Figures are the figures in a number that are meaningful and are digits with no zeros. Those zeros can be traced in a number like <em><u>“</u></em><em><u>3</u></em><em><u>2</u></em><em><u>0</u></em><em><u>”</u></em>, or <em><u>“</u></em><em><u>5</u></em><em><u>6</u></em><em><u>7</u></em><em><u>0</u></em><em><u>.</u></em><em><u>0</u></em><em><u>0</u></em><em><u>4</u></em><em><u>5</u></em><em><u>”</u></em>. Those zeros are not counted when counting the significant figures.
I hope you understand.
Answer:
D = rt
b, slower plane
8.5(3b) - 8.5(b) = 1649
25.5b - 8.5b = 1649
17b = 1649
b = 97mph
3b = 291mph
the length of the rectangle is 10ft
Step-by-step explanation:
let the length = x
width = x - 4
area = length X width
so, according to the problem
x(x-4) = 60
or,
- 4x = 60
or,
-4x -60 = 0
or,
- 10x + 6x -60 = 0
or, x(x-10) +6(x-10) =0
or, (x-10)(x+6) = 0
x = 10 ( x= -6 for length this value is not possible)
so length is 10ft
width = 10 - 4 = 6ft
Answer:
2:1
Step-by-step explanation:
well we show ratio by the sign ' : '
ratio of iced tea to lemonade= 12:6
now we reduce it to minimum by dividing it with same number.
12 is divisible by 6
so,
the reduced form is = 2:1
therefore,
ratio of the number of students who want iced tea to the number of students who want lemonade = 2:1.
