2/5 * 10 = 20/50
0.22 as a fraction 11/50
20/50 is the same as 40/100
11/50 is the same as 22/100
multiply
880/10000
which is 22/250
Anyone help with my geometry quiz please
Answer:

Step-by-step explanation:
- Our equation is
- Now there are 2 ways you can do this, I'll show you the shortcut
- If you have an equation like this, just take the value in parenthesis and equate it to zero
is the x of the vertex- Put this back into the equation
this is the y
Answer:
78
Step-by-step explanation:
6*10=60
2*9=18
60+18=78
Answer:
AC = { 4, 5, 6, 7 }
Step-by-step explanation:
If you see, the diagonal AC forms two triangles, Δ ABC, and Δ ADC. In Δ ABC, AC = 3 units and BC = 6 units, while AC is yet to be known. Respectively in Δ ADC, AD = 4 units and CD = 4 units, while AC is again yet to be known.
In both triangles the triangle inequality can help find the possible value( s ) of AD, as this inequality only restricts some of the possible values with which AC can take. At the same time AC is shared among the two triangles, so if we can apply the Triangle Inequality to both of these triangles, the value of AC can be " further restricted. "

And there we have two inequalities, 3 < AC < 9, and 0 < AC < 8. Combining both inequalities the only possible integer values for AC would be 4, 5, 6, and 7.
