When two shapes are mathematically similar, that means that all their sides are in a proportion.
We know the sieds of EH and AD, and so we can find the proportion of the shapes using these two sides.
EH/AD = 6/9 = 2/3
The ratio of EFGH to ABCD is 2:3
Now we have to find BC.
Becuase they're in proportion, we can form this equation:
= 
Cross multiply:
24 = 2*BC
Divide both sides by 2:
BC = 12 cm
Good luck!
Answer:
Yes
Step-by-step explanation:
Isosceles triangle with base of 3 units and sides of 5 units
Answer:
9/10
1/2+2/5
Since these fractions have different denominators, we need to find the least common multiple of the denominators.The least common multiple of 2 and 5 is 10, so we need to multiply to make each of the denominators = 10
1/2 ∗ 5/5 = 5/10
5/2∗ 2/2= 4/10
Since these fractions have the same denominator, we can just add the numerators
5/10+ 4/10 = 9/10
Answer:
6 days
Step-by-step explanation:
First, we make common denominators:
3 *2 = 6
_ -> _
4 *2 = 8
and we get 6/8
6/8 divided by 1/8 will be 6 days
