The solution step by step. 43 comes from adding all the given numbers together.
Answer:
A) 40 feet.
B) 7 inches.
Step-by-step explanation:
A) To acquire 8 inches, multiply the corresponding scale factor by 8:
1 inch equals 5 feet; 8 inches equals 40 feet
The genuine house stands 40 feet tall.
B) You can write the percentage if you want...
dwg / (35 feet) = 1 in / (5 ft)
When you multiply by 35 feet, you get...
7 in dwg = (1 in)(35 ft)/(5 ft)
In the scale drawing, the home measures <em>7 inches in length</em>.
c.) $3.38
Original price = $2.60
* It is the basis of increase thus, 100%
* The increase is 30%, thus, 100% + 30% = 130%
To get the new price, simply multiply the original price to 130%
$2.60 * 130% = $3.38
Another way of solving the problem is getting the equivalent of 30% and adding it to the original price.
$2.60 * 30% = $0.78
$2.60 + $0.78 = $3.38
FALSE. You'd have to multiply each by 12n to get rid of the denominators.
