Answer:
<h2>A. (0, 4)</h2>
Step-by-step explanation:
The equation of a circle:
(h, k) - center
r - radius
We have the equation:
h = 0, k = 4, r = 5
Answer:
290 in^2
Step-by-step explanation:
Answer:
NG ( first and last letter of NBG) = WS ( first and last letter of WTS).
BG = TS
G = S
N =W or NG = WS; BG = TS; G = S; N = W.
Step-by-step explanation:
We use the congruence statement to answer these questions. From the way the congruence statement is written, we can see that N = W (they are in the same relative position in the congruence statement). We also see that G and S are in the same relative position, so G = S.
Since N = W and G = S, this means that NG = WS.
From the congruence statement we can also see that B = T (they are in the same relative position). Since G = S, this means that BG = TS.
Answer:
a=50 b=20
Step-by-step explanation:
Call A and B the 2 present ages.
Ten years from now, A is twice as old as B -->
(A + 10) = 2(B + 10) (1)
Five years ago, A was 3 times as old as B -->
(A - 5) = 3(B - 5) (2).
Solve the system (1) and (2).
From (2) --> A = 3B - 15 + 5 = 3B - 10.
Replace this value of A into (1) -->
3B - 10 + 10 = 2B + 20 --> B = 20. Then,
A = 3B - 10 = 60 - 10 = 50.
Check
!0 years from now --> A = 60 and B = 30 --> A = 2B .OK
5 years ago --> A = 45 and B = 15 --> A = 3B. OK
