nora has 3/4 as many books as victor. let v represent the number of books victor has. create an expression to represent the numb
xxTIMURxx [149]

Answer:

N = \frac{3}{4} * v

Step-by-step explanation:

Since the value that we are provided is a fraction that is tied to the number of books that Victor has, we would simply need to multiply this fraction by the total number of books that Victor has. This value is represented by the variable v while the total number of books that Nora has is represented by the variable N. Therefore, the expression would be the following

N = \frac{3}{4} * v

The architect drew a design for the new kitchen. What is the area of the kitchen drawing?
nordsb [41]

Answer:

24

Step-by-step explanation:

Area of the kitchen = Area small rectangle + area large rectangle + area triangle

Area small rectangle = (8-4)*1.5

Area large rectangle = (8-4)* 3

Area triangle = (1/2)*base*height = (1/2)*4*3

Area of the kitchen = (8-4)*1.5 +  (8-4)* 3 + (1/2)*4*3 = 24 cm²
