Answer:
9 canvases
Step-by-step explanation:
To find the number of canvases Rogelio can buy, we just need to divide the value of the gift card by the value of each canvas. Then, if the result is decimal, we round down, because if we round up we will not have enough money to buy them all.
So we have that:
Number of canvases = 100 / 10.99
Number of canvases = 9.099
Rounding down, we can buy 9 canvases

The dimensions of screen are height 20cm and width 30cm
• In Mathematics, rectangle is a four sided polygon, having all the internal angles equal to 90.The opposite sides of the rectangle are equal in length which makes rectangle different from square.
• Area of rectangle is the product of length and breadth of rectangle. Perimeter of rectangle is twice the sum of its length and breadth.
• Area = l*b
Perimeter = 2(l+b)
The width of the laptop screen is 10 cm more than the height and the area of the screen is 600cm2.
Let the height of the screen be x cm
Width of the screen will be = x+10 cm
Area of screen = width * height
Area given = 600 cm²
x(x+10) = 600
x²+ 10x = 600
Solving Quadratic Equation
x²+10x -600=0
x² +30x-20x-600=0
x(x+30) – 20(x+30) = 0
(x-20)(x+30)= 0
x = 20 and x = -30
As the value of the height of the screen cant be negative. So x = 20
Height = 20cm
Width = 20+10 = 30cm
Therefore, the dimensions of screen are height 20cm and width 30cm .

Answer:
B) 36x^13*y^7
Step-by-step explanation:
The two rules of exponents that apply are ...
- (a^b)^c = a^(b·c)
- (a^b)(a^c) = a^(b+c)
Expanding the second factor gives ...
(4x^3*y^5)(3^2*x^(5*2)*y^2)
= 36*x^(3+10)*y^(5+2)
= 36x^13*y^7 . . . . . . matches selection B
