Answer:
Lateral Surface Area: 56 in²
Total Surface Area: 81 in²
Step-by-step explanation:
To find the lateral surface area, all we need to do is find the surface area for one of the lateral faces and then multiply it by 4.
![\frac{1}{2} *b*h](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2Ab%2Ah)
![\frac{1}{2} *5*5.6=2.5*5.6=14](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2A5%2A5.6%3D2.5%2A5.6%3D14)
Now the area of all the lateral faces:
14*4=56
The total surface area is the lateral area plus the base.
56+(5*5)=56+25=81
.075 will be written as 75/1,000. The fraction can then be simplified to the fraction 3/40.
Answer:
x = 4
Step-by-step explanation:
1.5(x + 4) – 3 = 4.5(x – 2)
Distributive property
1.5x + 6 - 3 = 4.5x - 9
1.5x + 3 = 4.5x - 9
1.5x - 4.5x = -9 -3
-3x = -12
x = 4
2x-25=x+5 move your “x” on the right side to the left side but to move it you need to switch the sign to cancel it out on the right. That ends up giving you x-25=5. You want X by itself so you move over your “25” but also change the sign. Giving you x=30
To find your y you set the equation to 0. 9y+28=0. You want Y by itself, so you want to move the 28 over first. Switch the sign which gives you 9y=-28. To get y alone divide by 9. 28/9 = 3.1(repeating 1)
