Answer:
∠4 and ∠3
∠4 and ∠5
∠3 and ∠6
Step-by-step explanation:
A pair of angles is said to be supplementary when the 2 angles add up to give 180°.
Two right angles add up to give 180°. Also, if we have two angles on a straight line, their sum = 180°, according to the linear pair property.
Thus, since m< 3 is given as 90°, m<4 = 90°.
m<4 + m<3 = 180°.
Therefore, <4 and <3 are supplementary.
<4 and <5, <3 and <6 are both linear pairs, therefore they are also supplementary.
Answer:
70%
Step-by-step explanation:
First, convert 0.3 into a percentage;
To do so, convert it 0.3 into a fraction then multiply by 100;
0.3 into a fraction = 3/10
3/10 into a percentage = 
The 10 at the bottom cancels out one zero at the top and you are left with 30.
Therefore percentage in Carlos' monthly savings is = 30%
Next, calculate the percentage NOT put in savings
percentage NOT put in savings = 100% - percentage in savings;
That is ; 100% -30% =70%
Hence, 70% of his income is not put into savings.
Answer:
$31.8
Step-by-step explanation:
Assuming the 6% tax is separate from the $30, we can use this equation:
Total = Cost + Tax (pretty self explanatory)
Method 1
Total = $30 + (6% * $30)
Total = $30 + $1.8
Total = $31.8
Method 2
Total = $30 * 1.06 (The 1 is the original cost, the .06 is the 6% tax)
Total = $31.8
