Answer:
There are 12 bills of 10$ and 11 bills of 20$
Step-by-step explanation:
Let
x ------> number of 10$ bills
y -----> number of 20$ bills
we know that
x+y=23 -----> x=23-y -----> equation A
10x+20y=340 ----> equation B
substitute equation A in equation B and solve for y
10(23-y)+20y=340
230-10y+20y=340
10y=340-230
y=110/10=11
Find the value of x
x=23-y ----> x=23-11=12
therefore
There are 12 bills of 10$ and 11 bills of 20$
Answer:
2/3
Step-by-step explanation:
find a number that when multiplied by 36 gives you 24 (divide 24 by 36)
use the number:
36•2/3=24
1•2/3=2/3
It is a semicircle so you'd use this formula for the area:
πr² / 2
Then substitute 2 into r and solve (2 because it's the radius, 4 is the diameter)
You would use this formula for the perimeter:
(πd / 2) + d
or
πr + 2r
Then substitute 4 into d / 2 into r and solve.
Hope I helped :)
