zoo is the answer....................................................................
Part A:
x - total number of liters ( milk + water )
0.2 x + 1 = x
Part B :
0.2 x + 1 = x
0.8 x = 1
x = 1 : 0.8 = 1.25 lit.
Milk:
1.25 x 0.2 = 0.25 lit.
Answer: 25/100* 88
Step-by-step explanation:
Answer:19. 17 degrees
20. 49 degrees
Step-by-step explanation:
Because of the postulate 50+?=67
So ?=17
And 20.
94+?=143
So
?=49
(Edit)I though you only meant 19 and 20
21. X=8
22. X=12
23.x=8
24.x=7
The cardinal number of set A is 9
<h3>How to determine the cardinal number?</h3>
The set is given as:
A = {x|x is a letter in the word introduce}
This means that the set A is:
A = {i,n,t,r,o,d,u,c,e}
The cardinal number of set A is represented as:n(A)
i.e. the number of elements in the set.
When the characters are counted, we have:
n(A) = 9
Hence, the cardinal number of set A is 9
