Answer:
x = 5.01%
y = 11.1
Step-by-step explanation:
Model:
50% of 120 is 60
Rate (%) = 50
Base (of) = 120
Percent (is, part) = 60
Thus, x in the first problem is the rate.
. Cross multiply, and we get:
x = 5.01
To check, multiply 5.01% × 60 = 3.006
For the second problem, multiply 10% with 111 to get the percent, which is 11.1
Answer:
RED 453.73km
Step-by-step explanation:
So what I'm going to do is find the area of it as if it was a full circle then cut it in half.
So the formula to find the area of a circle is A =
So to find r (radius) cut the diameter in half. 34/2 = 17
Plug in
A =
A = 907.46
Now cut it in half
453.73km would be the answer

Answer:
(a) 15
(b) 40
Step-by-step explanation:
(a) There are 20 counters, and the probability of selecting a white counter is 0.75.
0.75 = x / 20
x = 15
(b) The probability changes to 0.25. The number of black counters that must be added is:
0.25 = 15 / (20 + x)
20 + x = 60
x = 40
