Answer:
x=9
EF=7
FG=20
Step-by-step explanation:
2x-11 + 4x-16=27
6x-27=27
+27 +27
6x=54
6x/6=54/6
x=9
EF= 2(9)-11
18-11=7
FG=4(6)-16
36-16=20
Hey there! I'm happy to help!
First, let's find the radius. The radius is half of the diameter.
8.4/2=4.2
Here's how to find the area of a circle.
Square the radius.
4.2²=17.64
And multiply by pi (3.14 in our case)
17.64(3.14)=55.3896
We round to the nearest tenth, giving us an area of 55.4 ft²
Have a wonderful day! :D
He makes it up by 1/3=.333%=$75*1.333=$99.98
he then discounts it by 20%=1/5=99.98/5=$19.99
If the original profit is $99.98-$75=$24.98
and then discounted by $19.99
it would be $24.98-$19.99
=
$4.99
By the inclusion/exclusion principle,
n(J ∩ K) = n(J) + n(K) - n(J U K)
n(J ∩ K) = 285 + 197 - 431
n(J ∩ K) = 51
