Answer:
9
Step-by-step explanation:
Each pen can only hold 8 pigs, and pens cannot be split up into fractions.
Divide. 71 / 8 = 8.875
There is no 7/8 of a pen, so you must round up.
8.875 → 9.
Answer:
The graph of the equation 40.51x+12.45y=666.64 is attached with the answer where the horizontal axis represents the X axis and the vertical axis represents Y axis.
To plot the graph physically just find two points lying on the line. Mark the points on the graph sheet and then join them. This will give you the line represented by the equation.
To find points on the line assume the value of any one variable, substitute it in the equation, then solve the equation to find the value of other variable. For example : assume y = 1; substitute the value of y in the equation;
⇒ 40.51x + 12.45×1 = 666.64
⇒ 40.51x = 666.64 - 12.45
⇒ 40.51x = 654.19
⇒ x = 
⇒ x ≈ 16.149
Therefore point ( 16.149 , 1 ) lie on the graph of the equation.
***Only two points are required to plot this graph just because it represents a straight line, that we can conclude just by observing the equation. If in an equation the power of x is 1 or 0 and power of y is 1 or 0 then only it will represent a straight line in 2-D plane.***
Answer:
the answer is 6.1
Step-by-step explanation:
h= A over B (means you divide) and you get 6.1
The square root of 45 is simplified to 3 root 5. Rounded in decimal form, 6.708
Answer:
21
Step-by-step explanation:
The answer is 21 because for finding the area you have to multiply, 7 and 3.
Multiply 7 and 3 you get 21.
Hope this helps :)
