Answer:
b = 7.56 cm
Step-by-step explanation:
Sum of the angles in a triangle = 180
so m∠A = 180 - 75 - 36 = 69 ;
use the law of sines:
(sin A) / a = (sin B) / b = (sin C) / C.
Now plug in ∠A = 69 into formula (sin A) / a = (sin B) / b and solve for b:
(sin 69) / 12 = (sin 36) / b
cross multiply:
b sin 69 = 12 sin 36 divide each side by sin 69
b = {12 sin 36} / sin 69
b = (12 sin 36) / sin 69 = 7.555........
b = 7.56
Answer:
The answer is B ⅚ because there's only one out of 6 chance that the spinner will land on 6.
Answer:
Since (x−2) is a factor of the polynomial 3x
3
−2x
2
+kx−6=0, we have
p(2)=0
i.e. 3(2)
3
−2(2)
2
+k(2)−6=0$
i.e. 24−8+2k−6=0
i.e. 2k=−10
i.e. k=−5.
Step-by-step explanation:
4x+15y=G insert total hours- 30.5 for x and 1 for y and G will be your answer to problem B
Explanation:
Model: 1903
5 inches= 16 feet
wingspan=12.5 inches
In feet is the actual wingspan. Basically you set up an equation
Next you can cross multiply which is 5*y / 16*12.5 and get 5y=200
After you isolate y by dividing by 5 on both sides.
Y=40
Answer: The wingspan of the actual flyer is 40 feet.
