A.
Find the dimensions of the original painting.
Since the scale is 1 in : 40 cm
2 in ( 40 cm / 1 in) = 80 cm
1.5 in ( 40 cm / 1 in) = 60 cm
80 cm by 60 cm
B.
Find the area of the original painting.
<span>A = 80
cm x 60 cm = 4800 sq cm</span>
C.
Since 1 inch is 2.54 cm, find the dimensions of the original painting in
inches.
80 cm ( 1 in / 2.54 cm) = 31.5 in
60 cm ( 1 in / 2.54 cm) = 23.6 in
D,
Find the area of the original painting in square inches.
A = 31.5 in x 23.6 in = 743.4 sq in

Answer:
Option b
Step-by-step explanation:
To represent this proportion using fractions, let the numerators be the number of waffles sold and denominator, the number of sugar cones.
Thus, the proportion that can be used to represent the cone sales is
14/6 = 7/3
Answer:
The answer to your question is: 83 + 6
Step-by-step explanation:
This is a square of a binomial.
(2
+ 3
1.- Square of the first term
( 2
= 4(5) = 20
2.- Twice the product of the two terms
(2)(2
(3
= 6
3.- Square of the second term
(3
= 9(7) = 63
4.- Write the solution
20 + 6 + 63
83 + 6
Answer:
7 : 5
Step-by-step explanation:
let the age of the younger be x , then the older is x + 18, thus
x + x + 18 = 108, that is
2x + 18 = 108 ( subtract 18 from both sides )
2x = 90 ( divide both sides by 2 )
x = 45
Thus younger is 45 and older is 45 + 18 = 63
ratio older : younger = 63 : 45 = 7 : 5
