E ∩ F = {}
Step-by-step explanation:
Intersection is an operation performed on sets. In intersection, the common elements of the sets involved are written,
Given
E = {1, 2, 3}
F = {101, 102, 103, 104}
We have to find the intersection of both sets as indicated
So,
E ∩F = {1, 2, 3} ∩ {101, 102, 103, 104}
E ∩ F = {}
As there are no common elements in both sets the intersection will be an empty set

You have to do 1.5 times 2 and that equals something and that times 1.7
Terminating decimals firstly are decimals that finish...
To transfer 19/25 to a decimal we have to get it out of 100.
To do this, multiply 19 by 4, and 25 by 4.
This gives you 76/100.
From here you can easily see the decimal is 0.76.
= 0.76

Step-by-step explanation:
sports store sells three different packs of tennis balls. Brand A costs $2.50 for two balls, brand B sells three balls for $3.90, and brand C has a sale of four balls for $5.12. Which inequality about the unit price per ball is correct
Brand A:
$2.50 for 2
Brand B :
$3.90 for 3
Brand C:
$5.12 for 4
We calculate the unit price :
Brand A:
$2.50 / 2 = $1.25
Brand B:
$3.90 / 3 = $1.30
Brand C:
$5.12 / 4 = $1.2
