Answer:
Step-by-step explanation:
a. HM = 14
HN = 21
HK = 10.5
Based on intersecting chords theorem,
HK*HJ = HM*HN
10.5*HJ = 14*21 (Substitution)
HJ = 294/10.5
HJ = 28
b. VC = 7.2
VG = 12
Based on tangent-secant theorem, thus:
VD*VC = VG²
VD*7.2 = 12²
VD = 144/7.2
VD = 20
Therefore,
CD = VD - VC
CD = 20 - 7.2
CD = 12.8
Answer:
26hr
Step-by-step explanation:
12 calls/hr
480 calls/wk
If Juanita has made 168 calls this week, it meants she still has to make 312 calls. So, 312 calls ÷ 12calls/hr = 26hr
Juanita needs to work 26hr mores to reach the weekly goal.
To get the answer, you need to solve the equation for x = 7.
f(7) = 3/7 + 2 - sqrt(7) - 3.
= 3/7 - 1 - sqrt(7).
If you need to simplify it further:
= -4/7 - sqrt(7).
If you need it in decimal form: = -3.2171798824
The <em>correct answer</em> is:
C) x/21
Explanation:
Since Person 1 can complete the entire job (100% = 1/1 = 1) in 21 minutes, this person can complete 1/21 of the job per minute. This is Person 1's rate. If x is the amount of time it takes both people together to finish the job, then the amount of work Person 1 does would be (1/21)(x) = x/21.
