Answer:
It took Betty 1 hour 24 minutes to bake 1 cake.
Step-by-step explanation:
1) Convert to minutes. 4 hours 12 minutes = 252 minutes
2) Divide by 3 (number of cakes). 252 minutes divided by 3 is equivalent to 1 hour 24 minutes or 84 minutes.
12 x 9 = 108
2 x 9 = 18
108 + 18 = 126

Fo a circle with radius, r and center (h,k)
te equation is
(x-h)²+(y-k)²=r²
d/2=r
8/2=4=r
center is (-2,-3)
(x-(-2))²+(y-(-3))²=4²
(x+2)²+(y+3)²=16
Answer:
653
Step-by-step explanation:
The surface area of the larger cube is
2(10 x 7) + 2(12x7) + 2(10x12) = 140 + 168 + 240 = 548
The surface area of the smaller cube (minus the surface that is covered by the other figure)
4(8x3) + 1(3x3) = 96 + 9 = 105
105 + 548 = 653
