Answer:
L1 = 18 cm
W1 = 14 cm
A1 = 252 cm²
Step-by-step explanation:
Since the small rectangle is ½ the scale drawing of the original figure, therefore the dimensions of the smaller rectangle would be half of that of the original.
Thus:
Length (L) of the original = 36 cm
Length (L1) of the smaller rectangle = ½(36) = 18 cm
Width (W) of the original = 28 cm
Length (W1) of the smaller rectangle = ½(28) = 14 cm
Area (A1) of the smaller rectangle = L1 × W1 = 18 × 14 = 252 cm²
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.
Its 36% of 12
36/100×12= 4.32
so it atleast four, which is b.
Think that may help
Answer: 30 percent of 20 is 6.
_______________________________________________
Step-by-step explanation:
_______________________________________________
(n/100) * 20 = 6 ?
Solve for "n" .
_______________________________________________
Divide each side of the equation by "20" :
{ (n/100) * 20 } / 20 = 6 / 20 ;
to get:
n/100 = 6/20 ;
↔ 6/20 = n/100 ; solve for "n" ;
Look at the denominators:
20 * ? = 100 ?
100/ 20 = ? ;
100/20 = 5 ;
So, 20 * " 5" = 100 ;
Then 6* 5 = "n" (for the numerator, "n"; in : "n /100" ) ;
→ 6 * 5 = 30 ;
→ n = 30 .

Answer:
Only one solution.
Step-by-step explanation:
We have to solve for x from a linear single variable equation of x.
We have to determine the number of the solution of the given equation.
The equation is 
⇒ x + 12 = 8x - 2
⇒ 7x = 14
⇒ x = 2
So, there is only one solution of the given equation of x. (Answer)
