= 3.60
Solution:
We have the equation:
14.4 ÷ 4 = 3.60
Calculated to 2 decimal places.
c. 4.6
21 X .22= 4.6
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.

In number 2 the answer is 23cm because 437÷19 is equal to 23
Answer:
Step-by-step explanation:
Let c ----> Cat
t ------> Table
f ---------> Frog
From the first figure,
c + t -f = 170 -----------(i)
From the second figure,
f + t -c = 130 ---------(ii)
Add (i) and (ii)
(i) c + t -f = 170
(ii) <u>f + t -c = 130</u> {c & -c and f & -f gets cancelled
2t = 300
t = 300/2
t = 150 cm
The table is 150 cm tall
