The circle graph shows the results of a survey by a bakery on which of their new products 105 customerspreferred most. How many
Katen [24]

If 105 customers were the total, and 35% prefers cake, we must calculate 35% of 105, then we must do 105 multiplied by 35%, we can doit transforming the 35% in the fraction notation:

35\%=\frac{35}{100}

And the multiplication

105\cdot\frac{35}{100}=36.75

Therefore, if we round it to the nearest whole number, the number of customers that prefer cake is 37.

37 customers prefer cake.

What is the area of a rectangle with a length of (x - 5) and width of (x + 8)?
dlinn [17]

Answer:

a = x² + 3x - 40

Step-by-step explanation:

a = l * w

a = (x - 5)(x + 8)

a = x(x + 8) - 5(x + 8)

a = (x² + 8x) + (- 5x - 40)

a = x² + 3x - 40
