Give the known angle (90) a pronumeral of r.
give the second angle (the one with all the subtraction) a pronumeral or x.
give the third angle the pronumeral of y
x = 7y - 6
90 + x + y = 180
90 + 7y - 6 + y = 180
90 + 8y - 6 = 180
90 + 8y =186
8y = 96
y = 12. the third angle is 12
so 12 + 90 = 102
the second angle must equal 88 to make it to 180
H = cost of horseback riding per hr, p = cost of parasailing per hr
3h + 2p = 192...multiply by 2
2h + 3p = 213..multiply by -3
------------------
6h + 4p = 384 (result of multiplying by 2)
-6h - 9p = - 639 (result of multiplying by -3)
-----------------add
-5p = - 255
p = -255/-5
p = 51 <== cost of 1 hr for parasailing
3h + 2p = 192
3h + 2(51) = 192
3h + 102 = 192
3h = 192 - 102
3h = 90
h = 90/3
h = 30 <== cost of 1 hr of horseback riding
Answer:
¼
Step-by-step explanation:
From the question given above, the following data were obtained:
Blue (B) seed = 3
Purple (P) seed = 1
Total (S) = 1 + 3 = 4
The probability of her choosing a purple seed can be obtained as follow:
Event of purple seed, n(P) = 1
Total, n(S) = 4
Probability of purple seed, P(P) =?
P(P) = n(P) / n(S)
P(P) = ¼
Therefore, the probability of her choosing a purple seed is ¼.
