Answer:
E: 22%
Step-by-step explanation:
Area of the whole page:
30 × 40 = 1200cm²
Area of inner page (excluding margins):
(30-4) × (40-4) = 26 × 36
= 936cm²
Area of margins:
1200 - 936 = 264
To find percentage: 
× 100 = 22%
Answer:
4
Step-by-step explanation:
We need to perform a multiplication.
The following rule is applied:
A/B C = AC/B
In our example, the factors in the new numerator are:
28, 1,
Notice that all non-fraction factors are placed in the numerator.
The only factor in the new denominator is:
7
We need to reduce this fraction to the lowest terms.
This can be done by dividing out those factors that appear both in the numerator and in the denominator.
In our example, this is the common factor:
7
We need to evaluate a power by multiplying the base by itself as many times as the exponent indicates.
In our example, base 2 will be multiplied by itself twice.
Then we're left with our answer: 4
Answer:
D) 0
Step-by-step explanation:
In a ║gm, opposite sides are parallel and equal.
So,
RS = UT
=> x+5 = 2x+5
=> 2x-x = 5-5
=> 2x = 0
=> x = 0
Answer:
The answer should be -5.
Step-by-step explanation:
Remember that if there are two negative signs next to each other then it will turn into a positive sign, in which you get the equation -9 + 4. Your answer should be -5 when you add 4 from -9.
