In the scale used on a blueprint, 1/4 inch represents 3 feet. on the blueprint, what is the length of a room with an actual length of 24 feet?

length of room on blueprint will be = 2 inch.

Step-by-step explanation:

The scale used on a blueprint is

1/4 inch = 3 feet

Then we have to calculate the length of a room on scale with an actual length of 24 feet.

To solve these questions of conversion from one unit to other we should always use unitary method.

∵ 3 feet actual length represents the length on scale = 1/4 inch.

∴ 1 feet actual length will be represented on scale = (1/4)/3 = 1/12 inch.

∴ 24 feet actual length will be measured on scale = (1/12)×24 = 2 inch.

Therefore answer is 2 inch.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
