Answer:
8 pigs and 2 ducks
Step-by-step explanation:
You put this into the equation x+y=10; 4x+2y=36 to get your answer. You can then solve it.
<span>The problem is to calculate the angles of the triangle. However, it is not clear which angle you have to calculate, so we are going to calculate all of them
</span>
we know that
Applying the law of cosines
c²=a²+b²-2*a*b*cos C------> cos C=[a²+b²-c²]/[2*a*b]
a=12.5
b=15
c=11
so
cos C=[a²+b²-c²]/[2*a*b]---> cos C=[12.5²+15²-11²]/[2*12.5*15]
cos C=0.694------------> C=arc cos (0.694)-----> C=46.05°-----> C=46.1°
applying the law of sines calculate angle B
15 sin B=11/sin 46.1-----> 15*sin 46.1=11*sin B----> sin B=15*sin 46.1/11
sin B=15*sin 46.1/11-----> sin B=0.9826----> B=arc sin (0.9826)
B=79.3°
calculate angle A
A+B+C=180------> A=180-B-C-----> A=180-79.3-46.1----> A=54.6°
the angles of the triangle are
A=54.6°
B=79.3°
C=46.1°
D = number of dogs washed
c = number of cats washed
d = (60 - 5c) / 7.50
The 7.50 should be underneath the brackets
Answer:
3/6 or 50%
Step-by-step explanation:
The probability of rolling an odd number from the dice numbered, {1,2,3,4,5,6} is 3/6.
6 numbers in all.
3 odd numbers.
3 even numbers.
Therefore, 3/6 or 50%.
Y/3=6 and 4y/9=8 and since it asks for the sum the ANSWER IS 14!
