Answer:
$41?
Step-by-step explanation:
Well, if he's overdrawn, then he doesn't have any money, he owes money. But I'm assuming they want to add. The sister has $23 more than he does, so add.
18+23=41.
So his sister has $41.

1. find the area of the two triangles, including the shaded section. the formula for this is a=1/2bh
the height and base are both 24 inches. this is because you add the 10 from the side of the square to the 14 that is given
so:
a=1/2(24)(24)
a=(12)(24)
a=288 sq. inches
since there are two triangles, you would multiply the area by 2
a=2(288)
a=576 sq. inches
now, since you only need the unshaded section, you have to take away the shaded section, which is a square. to do this, you must calculate the area of the square and take it away from the area of both triangles.
a=576-(lw)
a=576- (10)(10)
a=576-100
a=476 sq. inches
that is your answer
Answer:
Step-by-step explanation:
l= 4.2 m = 4.2 * 100 = 420 cm
b = 1.4 m = 1.4*100 = 140 cm
h =1.2 m =1.2 *100 =120 cm
Volume of cuboid = l*b*h = 420 * 140 * 120 = 705600 cubic cm
Volume of cube = a*a*a = 20*20*20 = 8000 cubic cm
No.of cubes = Volume of cuboid / volume of cube
= 705600 / 8000 = 882 cubes
or 420*140*120 / 20*20*20 = 42*14*12/2*2*2 = 21*7*6 = 882 cubes
Answer:
r = 10 cm = 1/2 diameter
h = 30 cm
V = 9424.78 cm3
L = 1884.96 cm2
T = 314.159 cm2
B = 314.159 cm2
A = 2513.28 cm2<span>

If you multiply 6 times 8 there are 48
