Answer:
6:15 and 8:20 are examples of additional equivalent ratios.
Step-by-step explanation:
The table is:
<u>Books (x) Cost (y)</u>
2 5
4 10
From the table, the ratio Books : Cost is 2:5 or 4:10. Equivalent ratios are obtained, using a graph, from the plot of the line that pass through these two points. In the figure attached, this line is shown. There, it can be seen that ratios 6:15 and 8:20 are equivalent to those from the table.
Answer:
1.2 cm
Step-by-step explanation:
Quadrilateral circumscribing a circle is a quadrangle whose sides are tangent to a circle inside it (see attached diagram).
The area of circumscribed quadrilateral is
where 
is semi-perimeter and r is radius of inscribed circle.
In your case, 
If a quadrilateral is circumscribed over the circle, then the sum of opposite sides is equal, so
so
Now
Answer:
12 feet long bc of cross multiplying then dividing the product by 10 which gives you 12!
Answer:
3/10
Step-by-step explanation:
There are 20 marbles. 6 of them are blue.
P = 6/20 = 3/10
Longitud = L Ancho = A
2A + 2L = 54
L = 2A Sustituir este valor por L en la primera ecuación:
2A + 2(2A) = 54
2A + 4A = 54
6A = 54
A = 9
También porque L = 2A,
L = 2(9) = 18
