Answer:
First you'd look at PEMDAS (parenthesis, exponent, multiplication, division, addition, and subtraction( you'd look at them in this order to solve the equation properly.))
So there is a parenthesis, that would be the 3(2^0). ignore the three, because you're focusing on the parenthesis. Any number other than zero with an exponent of zero will always be one. leaving you with 3(1).
So by now you should know (depending on your level of mathematics, That a number beside a single number in a parenthesis is multiplication. so 3 times 1.
Knowing that any number, other than zero, multiplied by 1 is the number itself, The answer is 3
In short, 3(2^0) = 3
Answer:
The constant proportionally of the graph is:
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get the equation
y ∝ x
y = kx
k = y/x
here 'k' is called the constant of proportionality.
From the graph, it is clear that:
at x = 0.5, the value of y = 4
so substituting x = 0.5 and y = 4 in the equation
k = y/x
k = 4/0.5
k = 8
at x = 1, the value of y = 8
so substituting x = 1 and y = 8 in the equation
k = y/x
k = 8/1
k = 8
Therefore, the constant proportionally of the graph is:
Answer:
58%
Step-by-step explanation:
The first thing that you have to do if figure out how many sandwiches are left we do this by the total - bad sandwiches = good sandwiches
12-5=7
There are 7 good sandwiches left. To figure out the percentage you do 
=
now we fill in the parts the part is 7, the total is 12 and the % is x
=
now we cross multiply, 7 x 100 and 12 x X
700=12x now we divide both sides by 12 so the x is alone
x = 58.33 now we round down because it ends in.3
x=58
Answer:
x=32
Step-by-step explanation: x/2-7=9 find what number minus 7 equals 9 multipy that by 2 and there you go that is the answer
