Answer:
small cups=30
large cups=40
Step-by-step explanation:
let x be the number of small cups and y the number of large cups.
-Given that 10 more cups than small cups of lemonade were sold:
#Before the 10 more were sold, the number of x and y sold were equal>
The number of small cups sold was 30
#Since, the number of large cups was 10 more, y=x+10=30+10=40
Answer:
49,850.64
Step-by-step explanation:
To find the area of a circle, you must use the formula pi r ^2 (pi r squared).
In this case, we are using 3.14 for pi, so we can add that into the formula.
3.1r^2
We also know the radius, so we can add that in too.
3.14 x 126 ^2
Now solve.
126^2 = 15,876
15,876 x 3.14 = 49,850.64
49,850.64 is the answer.
Hope this helped!

Answer:
$4000 was invested at 4%, 2500 was invested at 3%
Step-by-step explanation:
First and foremost the question has to be define.
Total amount raised is $6500
Savings account percentage simple interest =3%
Government Bond: 4% simple interest
Equation for amount invested at each rate:
(6500-x)0.03 + 0.04x = 235
195 - 0.03x + 0.04x = 235
0.01x = 40
x = 4000
$4000 was invested at 4%, 2500 was invested at 3%
