solution
this is what I did. total number of ways without any restriction =900. we have to subtract the case when at least one child doesn't get any fruit. let that be C1∪C2∪C3 and we use the principle of mutual inclusion and exclusion to find that. C1∪C2∪C3=C1+C2+C3−(all two intersections)+3 intersections (no one gets a fruit case) =3⋅60−3+1=178 so case where each child gets at least one fruit =900−178=722.
Is this right, someone saying answer =49
Answer:
110.9
Explanation:
Find the height of the triangle by using the Pythagorean theorem.
a^2 + b^2 =c^2
(16/2)^2 + b^2 =c^2
b^2= 192
b or height = 13.86
Area of triangle = (b*h)/2
Area of triangle = (16*13.86)/2
Area of triangle = 110.9

Answer:
Step-by-step explanation:
Let the dog walking job be x
And sales job be y
We have to form inequality by the given information:
Work a total of no more than 41 will give us
Next condition is: dog walking pays $5 and sales job pays $8 per hour and we have to earn atleast 254 it will give us
Hence,
And
X would equal 8 because 3 over 3 is equal to 1 so it would be 8 plus 1 equal 9
