Answer:
shade 10 boxes for 50%
Step-by-step explanation:
50%=50/100=1/2
1/2 of 20=10
:. To shade 50% of the boxes, 10 boxes need to be shaded
Here is something that can help you
I will solve one for you to get you a idea so next u can solve all
To know whether line is tangent toa circle or not we should know that that line is a tangent line of a circle if it intersects circle at single point.
and this will always be perpendicular at radius
so in problem
1)
diameter is given 7.5
and u can see they make a right triangle ABC if that is perpendicular so segment AB is tangent to a circle.
Lets see by applying <span>Pythagorean Theorem
</span>this is method we can say that this is in fact a right triangle
a^2=b^2=c^2
a,b are shorter side c is longer side
(7.5)^2+(8)^2=(17)^2
56.25+64=289
120.25=289
both are not equal so they are not forming right triangle so segment AB is not a tangent line.
Answer:
I don't know if I understood the question correctly, but this is what I have...
Step-by-step explanation:
If the "x" is a variable:
(2x-3)-(1-1)=
2x-3
If th "x" is a multiplication sign:
(2x-3)-(1-1)=
-6-0=
-6
i hope this helps
