Answer:
9 years
Step-by-step explanation:
Simple interest for any amount p is given by
SI = P*R*T/100
where R is the rate of interest
T is the time period in years
given
P =$1500
R = 4%
T we have to find
SI = $540
Thus, putting the given value in SI = P*R*T/100
540 = 1500*4*T/100
T = 540*100/1500*4 = 9 years
Thus, It will take 9 years for Sam to earn $540
Answer: 5 seconds
<u>Step-by-step explanation:</u>
Maximum height is the y-value of the vertex. The number of seconds at maximum height is the x-value (aka axis of symmetry).
h(x) = -2x² + 20x + 48
a=-2 b=20 c=48
Axis of symmetry: x = 
= 
= 
= 5
Answer:
The answer is $41.25 because the 2 jeans are $91 as a collective plus the supposed $41.25 shoes equals the total amount (assuming no tax) $132.25.

the question in English
Juan has blue cubes with a 55 mm edge and red cubes with a 45 mm edge. He stacks them in two columns, one of each color; he wants the two columns to be the same height. How many cubes does he need, as a minimum, of each color?
Let
x---------> the number of blue cubes
y--------> the number of red cubes
we know that
Juan wants that the two columns to be the same height
so

solve for y

I proceed to calculate a table, assuming values of x to calculate the value of y. When the values of x and y are whole numbers, I will have found the solution.
the table in the attached figure
therefore
<u>the answer is</u>
9 blue cubes
11 red cubes
