Anthony found a number that is 20% of 30% of 400 what percent of 45 is the number that anthony found

For this case we have:

1st step:

We look for 30% of 400 by a rule of three of the form:

400 -------> 100%

x -----------> 30%

Where x is given by the number that represents 30% of 400.

We have:

2nd step:

We search for 20% of the number found, that is, , using a rule of three:

120 -------> 100%

y -----------> 20%

Where y is given by the number that represents 20% of 120.

We have:

So, the number that Anthony found is 24.

3rd step:

According to the statement, we must find the% that represents the number of Anthony, based on the number 45. Through a rule of three we have:

45 -------> 100%

24 -----------> z%

Where z is given by the% that represents Anthony's number, knowing that 45 represents 100%.

We have:

%

The number of Anthony represents 53.33% of 45.

the answer is a

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
