What is 23+41-7×398-15
1 answer:
This question is just a type of question that you honestly just need to punch into a calculator. However, if you just do a simple one-over-one addition of 23 and 41, then subtract, it gets even easier. Then, do another one-over-one but this time as subtraction when you take away the 7. Then you will do yet another one-over-one but for multiplication with your sum of your numbers after subtraction. Finally, do another one-over-one to get your final answer of 22,671. I will attach a picture of what this looks like as well as an illustrated one-over-one. Hope this helped!

Answer:
The area of tarpaulin is 1315.63 ft^2.
Step-by-step explanation:
height, h = 20 feet
circumference, C = 102 feet
Let the radius is r.
Circumference, C = 2 x 3.14 x r = 102
r = 16.24 feet
Let the slant height is L.
The curved surface area is
S = 3.14 x r x L
S = 3.14 x 16.24 x 25.8 = 1315.63 ft^2
Answer:
Option B and C are correct.
are the expression incorrect for slope
Step-by-step explanation:
Slope is defined as the change in the dependent variable relative to the change in the dependent variable
or the ratio of the horizontal changes to vertical changes between any two points on the graph of the line.
The vertical changes between any two points is rise
The horizontal changes between any two points is run.
Formula for slope is given by:
For any two points and
then slope is:
or we can write this as:
Δy =
Δx =
⇒
Therefore, the expression which are incorrect for slope are;
