it might be claudia but i need more information im not sure take this with a grain of salt!!
Answer:
Hi,
Step-by-step explanation:
PR²=PQ²+QR²-2*PQ*QR*cos(51°)
=15²+12²-2*15*12*cos(51°)
=142,444659....
PR=11.9350...
PQ²=QR²+PR²-2*QR*PR*cos(R)
cos(R)=(12²+142.444...-15²)/(2*12*11.9350...)=0,21451112....
angle R=77,61315...°≈77.6°
angle P=180°-51°-77.6°≈51,4°
Benchmarks are 0%, 25%, 50%, 75%, and 100%. 50% is the closest to 52%, so it would be that.
Answer:
A = 83
B = 0.00656
C = 420
D = 498000000
E = 0.0000078
F = 0.000813
G = 80D497700
H = 0.05214
I = ?
J = 3.690426 x 10 (to the power of -1)
K = 1,605 x 10 ( to the 6th power?
L = 6.34 x 10 ( to the 2nd power)
Tell me which ones were right! And I hope this helps :D
Answer:
x =3.6666.... This can be rounded to 3.7
Step-by-step explanation:
-x + 4x + 1 = x+12 -x
3x +1 -1 = 12 -1
3x / 3 = 11 /3
3.6666...
Hope this helps! :)
