Answer:
3/7
Step-by-step explanation:
its 3/7 because there are 3 weekend days and there are 7 days in total in one week, so out of the week there is 3 weekend days.
i hope this helps :)
21, 18 1/2, 6.2, 1.75, -1/4, -1/2, -4,-5.9
50% since you have a half chance of getting 1 to 4 and other half is 4-8
Answer:
Please check the explanation.
Step-by-step explanation:
Ascending Order:
When we talk about the numbers to be arranged in ascending order, it means the numbers need to be arranged from smallest to largest.
For example, if we have to arrange the numbers from 1 to 5 in ascending order.
It means, the ascending order will be: 1, 2, 3, 4, 5
Now, let us arrange the given numbers in ascending order.
a) 2234 to 2238 2234 2235 2236 2237 2238
b) 4099 to 4103 4099 4100 4101 4102 4103
c) 3298 to 3302 3298 3299 3300 3301 3302
d) 7269 to 7273 7269 7270 7271 7272 7273
e) 6354 to 6358 6354 6355 6356 6357 6358
f) 8379 to 8383 8379 8380 8381 8382 8383
g) 7365 to 7369 7365 7366 7367 7368 7369
Answer:
Part A:
The surface area of a cylinder is given by
A= 6πr² if h= 2r
Part B:
Total Cost of covering the cylinder = Rate *2πrh + rate*2πr²
Cost of covering only the side = Rate *2πrh
Step-by-step explanation:
Part A:
The surface area of a cylinder is given by
A= 2πrh + 2πr²
Where h= height and radius = r
But we have the height twice as radius so h= 2r
So putting h= 2r we get
A= 2πr(2r) + 2πr²
A= 4πr² + 2πr²= 2πr²(2+1) = 2πr²(3)= 6πr²
Part B:
Cost = Rate * area of the wall + rate * area of the top and bottom
Cost = Rate *2πrh + rate*2πr²
Where area of the top and bottom= πr² +πr² =2 πr²
and area of the side = 2πrh
Multiplying both with the rate and then adding would give the total cost of materials needed to cover the outside of the cylinder and from top and bottom as well.
If you do not need to cover top and bottom then the expression would be
Cost of covering only the side = Rate *2πrh
Part C:
Already done above.
