Answer:
CD = (3/2)√2
Step-by-step explanation:
All the triangles are similar isosceles right triangles, so the hypotenuse in each case is √(1²+1²) = √2 times the length of the corresponding legs. BC is the hypotenuse of ΔBCD, so leg CD is that length divided by √2.
CD = BC/√2 = 3/√2
CD = (3/2)√2
Answer:
one solution
Step-by-step explanation:
X-9=0
Add 9 to each side
X-9+9=0+9
x = 9
There is one solution
10 cakes can be made
Explanation:
Convert 7 1/2 to an improper fraction
15/2 divided by 3/4
Flip the second fraction and multiply instead of divide
15/2 x 4/3
multiply the tops: 15 x 4 = 60
Over the bottoms multiplied together 2x3=6
60/6=10
therefore 10 cakes can be made
A number times 1 always equals itself, so: 4×1 = 4, OR 2×2 = 4
Answer:
im not completely sure but I'd say 30
Step-by-step explanation:
well I'm not sure but if they have the same base and altitude you'd think they might have the same volume, but I'm not exactly sure
