Answer:c 57
Step-by-step explanation:
The vertices of the attached triangle are
A(9, 0)
B(0, 4)
O(0, 0)The leg lengths of this triangle are 9 and 4 units. Its area can be computed using the formula for the area of a triangle.
A = (1/2)(9)(4) = 18 . . . . square units
Since the result of this calculation is 18 square units, we know it has the correct area.
_____
The area measuring tool in the drawing app also shows the area to be 18.
Answer:
5:2 , 30:12 , 60:24 , etc.
Step-by-step explanation:
To identify ratios equivalent to 15:6, all you need to do is multiply or divide both numbers in the ratio by the same amount to find an equivalent ratio.
So, for example:
1:2 --> 1*2 : 2*2 = 2:4 Both one half, so equal.
Now for 15:6...
Let's divide by the least common denominator ( 3 )
15 / 3 and 6 / 3 = 5 and 2
So 15:6 = 5:2
And we can also multiply the ratio by any constant as well...
For example 15 * 2 and 6 * 2
So 30:12 = 15:6

Answer:
1:11=11:121
5:2:1=35:14:7
1.5:1.25:2.4=6:5:9.6
Step-by-step explanation:
x/11=11/121 so x equals 1
5/2=x/14 so x equals 35
1.5/x=6/5 so x equals 1.25
1.25:2.4=5/x so x equals 9.6
