Answer: 214.8
Step-by-step explanation:
First move the decimal to the right, in this case 8.95 = 895., then multiply the 24 by 895. to get 21480., you then move the decimal to the left and you get 214.80 or 214.8.
check the picture below, that's pretty much the same block, or "rectangular prism", with a width of 10, length of 5 and height of 1.
so anyhow, is really 6 rectangles stacked up to each other at the edges, so, we can simply get the area of each of those rectangles, add them up and that's the surface area.
front and back, two rectangles of 5x1
left and right, two rectangles of 1x10
top and bottom, two rectangles of 10x5

Answer:
Step-by-step explanation:
You see that there’re angles with 30 and 90 degrees that means that -> 180-(90+30)=60 (measurement of the third angle)
Here you’ll need to use the 30,60,90 degree triangle rule:
The opposite side of 30 degree will be y
30->y
90->2y->12√3 => y=6√3
60->y√3->x => 6√3x√3=6x3=18
To understand the rule better you can check the picture below.Wish it will help you!Good luck!
The cost of company 1: 10x+50
The cost of company 2: 8x+60
The cost will be the same at:
![10x + 50 = 8x + 60 \\ 2x = 10 \\ x = 5](https://tex.z-dn.net/?f=10x%20%2B%2050%20%3D%208x%20%2B%2060%20%5C%5C%202x%20%3D%2010%20%5C%5C%20x%20%3D%205)
The answer is 5 hours
Answer:
65R3
Step-by-step explanation:
260/4 is a whole number, so then there would be a remainder 3. The only one with a r3 is D.
Hope this helps :D
