Answer:
J - Janeta's age M - mother's age
A) (J-5) = .2 * (M-5)
B) J = (1/3) * M
Subtracting 5 from both sides of B:
B) J -5 = (1/3)M -5
then we substitute the right side of this into the left side of A and we get
(1/3)M -5 = .2 M -1
.333333333333M -5 = .2M -1
.1111111111111111111M = 4
Mother's Age = 36
Janeta's Age = 12
Step-by-step explanation:
Answer:
A. 0.186524036
Step-by-step explanation:
Cosine 79° 15'
But, 1° = 60'
Thus; 15' = 15/60 = 0.25°
Therefore;
cos 79° 15' = cos 79.25°
Cos 79.25° = 0.186524036
= 0.186524036
x/10 + x/4 = 21 /*40
4x + 10x = 840
14x = 840
x = 60 = total number of points the team scored
Answer:
C. x = 15 * sin 18°
Step-by-step explanation:
sin A = Opposite / Hypotenuse
sin 18° = x / 15
x = 15 * sin 18°
4/5 acres of the land were sold.
40* 1/2 = 20
20* 3/5 = 12
12+20= 32
32/40 = 4/5 simplified
