Solve the inequality.<br> -4 (7 + 6x)< -2(x+3)<br>write in inequality integer form

VashaNatasha [74]

Answer:

-1 >x

Step-by-step explanation:

-4(7+6x)<-2(x-6)

-28-24x<2(x-6)

-28-24x<-2x-6

+6. +6

-22-24x<-2x

+24x +24x

-22 < 22x.

-22÷-22=1 that canceled out

+22÷-22= -1

-1>x. because we divided by a negative the inequality switched.

Can someone help me please???

My name is Ann [436]

Answer:

35,691

Step-by-step explanation:

First step, look at the diagram and you see that you have a sphere and a cone.

The total surface area of a sphere is

$A = 4\pi r^{2} \\A = 4\pi 39^{2} \\A = 19,113$

Since you only have half of a sphere, the surface area is 9,556.5

The surface area of the cone is

$A = pi r(r+\sqrt{h^{2}+r^{2} }) A = \pi39(39+\sqrt{42^{2} +39^{2} } \\A=11,800$

You don't need the bottom of the cone however as it is connected to the half sphere.

So substract the area of a circle with a radius of 39 from the product of 19,113 + 11,800

The area of the circle is 4,778
