Step-by-step explanation:
I multiplied -4 to 8
Have a wonderful day <33
The New pay in current year is = $ 2225
The old pay in the last year was = $ 2176
percentage (%) increase formula = (new value- old value ) *100 / old value
which becomes,,
which equals to 2.3% .
Hence, the average net pay per month increased is 2.3% .
Intersection of E and A: E n A = { 8 }
Union of E and A : E U A = { -2, 3, 0, 6 , 8 }
<em><u>Solution:</u></em>
<em><u>The sets E and A are given below:</u></em>
E = { -2, 3, 8 }
A = { 0, 6 , 8 }
<em><u>Find the intersection of E and A</u></em>
Intersection of E and A means that, set containing all elements of E that also belong to A
Therefore,
From sets E and A,
E n A = { 8 }
<em><u>Find the union of E and A</u></em>
union of E and A contains all elements of set E and set A
E U A = { -2, 3, 0, 6 , 8 }
Answer:
Step-by-step explanation:
Step-by-step explanation:
Let x miles/hr be the speed of the plane in still air and y miles/hr be the speed of the wind.
We have 10hr * (x + y)miles/hr = 880 miles
and 20 hr * (x - y)miles/hr = 880 miles.
=> (x + y) = 88 and (x - y) = 44.
Therefore 2x = 88 + 44 = 132 and x = 66.
The speed of the plane in still air is 66 miles per hour.
