Answer:

489 or -113

Step-by-step explanation:

Whats 30 times 30 plus 45 minus 456

rewrite in terms of numbers:

30 * 30 + 45 - 456

remember the order of operations and solve:

30 * 30 + 45 - 456

=900 + 45 -456

= 945 - 456

= 489

the answer could change depending on the placement of parenthesis, such as if the equation was:

30 * (30 + 45 -456)

solve with the order of operations:

30 * ( 30 + 45 - 456)

= 30 * (75 - 456)

= 30 *(-381)

= -11430

The ratio of a model building's dimensions to the building's actual dimensions is 1/52. If the height of the model is 15 inches,

g100num [7]

Set this up as a proportion with the model stuff on top and actual building stuff on bottom. $\frac{1}{52} = \frac{15}{x}$ . Cross multiply to get x = 780. The actual building is 780 inches. In feet that is 65.
