Answer:
Step-by-step explanation:
Given,(3x-2y,7)=(11,x+y)
So,3x-2y=11...............(i)
7=x+y
or,x+y=7................(ii)
Now,Multiplying eqn.(ii) by 2,we get,
2x+2y=14...........(iii)
Adding eqn(i) and eqn(iii),
3x-2y+2x+2y=11+14
or,5x=25
or,x=5
Substituting value of x in eqn(i),
5+y=7
or,y=2
Hence,the values of x and y are 5 and 2 respectively.
Answer:
4 times as tall.
Step-by-step explanation:
Volume of the box with the smaller base = 2*2* h1 = 4h1 where h1 is its height.
Similarly the volume of the larger base box = 4*4 * h2 = 16h2 with height h2.
So the ratio of their volumes is 16h2 / 4h1 = 4h2 / h1.
Now the volumes are equal so 4h2 = h1.
Therefore h2 = h1/4 so h1 = 4h2.
The box with the smaller base is 4 times as tall as the other box.

Answer:
$908.93
Step-by-step explanation:
-The effective loan amount is :
#We calculate the effective monthly interest rate:
#Now we use the formula below to calculate the monthly payments:
, Where S is the loan amount and P the monthly payments.
Therefore:
Hence, Baggio will make monthly payments of $908.93 each.
Answer:P: the principal, the amount invested
A: the new balance
t: the time
r: the rate, (in decimal form)
Ex1: If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years.
P = $1000, t = 2 years, r = 0.08.
A = 1000(1+0.08(2)) = 1000(1.16) = 1160
