Answer:
Step-by-step explanation:
3. Use Cosine law to find the length of the unknown side (PR)
q² = p² + r² - 2prCos Q
q is the opposite side of ∠Q;
p is the opposite side of ∠P; p = 33
r is the opposite sides of ∠R ; r = 67
q² = 33² + 67² - 2* 33*67 Cos 19°
= 1089 + 4489 - 4422 * 0.95
= 1089 + 4489 - 4200.9
= 1377.1
q = √1377.1
q = 37.1
PR = 37.1
To find the angle use law of sin
Sin P = 0.3
P = 17.5°
∠R = 180 - (19 + 17.5)
= 143.5°
If you let x represent the width of the rectangle, then you can write the equation for area as
.. x(2x +5) -63 = 0
This has positive solution x=4.5.
The rectangle is 4.5 meters by 14 meters.
Answer is b hope this helps you
Answer:
$1,250
Step-by-step explanation:
You can find the answer using the following formula:
i = Prn
i= interest= $400
P= principal
r= rate of interest=0.04
t= time periods= 8
You can replace the values you have in the formula and then, isolate P:
400= P*0.04*8
400=P*0.32
P= 400/0.32
P= 1250
According to this, the answer is that Anna borrowed $1,250.
Answer:
6 7/8
Step-by-step explanation:
To evaluate 5 + 1 7/8 we combine the integers 5 and 1 and to this sum add the fraction 7/8:
5 + 1 + 7/8 = 6 7/8 (six and seven eighths)
