X+x+2+x+2+2x-5=49
you would then combine all the x’s
which would equal 5x+2+2-5=49
the you would add up your numbers =ing
5x+-1=49
then add -1 to the other side of the = sign making the one positive which would equal
5x=50
divide by 5

Answer:

MN = 160

Step-by-step explanation:

We know that arc MN = arc NO

17g - 10 = 14g+ 20

Subtract 14g from each side

3g -10 = 14g-14g+20

3g -10 =20

Add 10 to each side

3g = 20+10

3g = 30

Divide by 3

3g/3= 30/3

g= 10

We want the arc MN

17g - 10

17(10) - 10

170 -10

160

Volume of the cone = 1/3 pi * 3^2 * 4 =  12pi
Volume of the hemisphere = 4/3 pi 3^3 * 1/2 =  18pi
So the volume of the toy =  12pi + 18pi = 30pi = 94.25 cm^3 to nearest hundredth Answer

Surface area of hemisphere = 1/2 * 4 pi 3^2 =  18pi
Lateral Surface area of the cone =  pi r l where l = slant height of the cone
Now l=  sqrt ( 4^2 + 3^2)  = sqrt25 = 5
So lateral S A = 3 * 5 * pi = 15pi

Surface area of the toy = 18pi + 15pi = 33pi = 103.67 cm^2 ( nearest hundredth)   Answer
