Answer:
see below
Step-by-step explanation:
Not knowing what properties you have to choose from, it'll be one that looks like ;
The base (a) stays the same;
the Numerator in the exponent is the exponent on the base;
and the Denominator in the exponent is the index (root number) of the radical.
Answer:
l=10 cm
Step-by-step explanation:
In a rhombus, the diagonals are cut into identical lines at the intersection.
This way, I found the measures of the halves of the diagonals in a right triangle, knowing that the diagonals of the rhombus are perpendicular on each other.
I calculated that AO = AC/2= 8, and that BO=BD/2= 6, and then I applied pytagora's theorem in a quarter of the rhombus, which is the right triangle AOB, to find the length of a side
Answer:
C, D and E
Step-by-step explanation:
Given
Represent solid beads with S and clear beads with C
So:
Required
Select operations that give an equivalent ratio
First, we need to get the unit ratio
Divide through by 4
-- This means that, after any operation. The equivalent ratio must be 2: 5
Option A: Add 2 to S and 2 to C
Perform the operation
Divide through by 2
Option B: Subtract 8 from S and 6 from C
Perform the operation
Option C: Multiply S and C by 2
Perform the operation
Divide through by 8
Option D: Divide S and C by 4
Perform the operation
Option E: Multiply S and C by 18
Perform the operation
Divide through by 72
<em>From the calculations above, options C, D and E gave an equivalent of 2:5.</em>
