Answer:
15degrees
Step-by-step explanation:
From the given diagram
<1+<2 + <DCB = 180
<1+<2+120 = 180
<1+<2 = 180 - 120
<1+<2 = 60
<2 = 60 - <1
<2 = 60 - 45
<2 = 15degrees
Hence the measure <2 is 15degree
Answer:
A
23/7 times 23/7
Step-by-step explanation:
Answer for Part A:
Elena makes more money than Jada does. Elena makes $1.40 more than Jada does.
Explanation for Part A:
The equation for Elena tells us that she makes $8.40 per hour. Jada makes $7 an hour. Since 8.4 > 7, Elena makes more money than Jada per hour
The probability of selecting a female student for the first picking is

The number of students left to select from after the first two students selected is 50 - 2 = 48 students, which consist of 34 females (two have been selected) and 14 males (none has been selected so far)
The probability that the third pick is a male is
3px = 2q(r-5x)
distribute
2qr - 10qx
3px = 2qr - 10qx
To solve for x
add 10qx to both sides
3px + 10qx = 2qr
factor out x
x(3p+10q) = 2qr
divide both sides by 3p+10q to isolate x
x = 2qr / <span>(3p+10q)
