Answer:
a) 81
Step-by-step explanation:
Number of sides of the polygon = 6
Sum of angles of the polygon = ( n - 2) * 180
= (6 - 2) * 180
= 4 * 180
= 720
n = 720 - (110 + 108 + 143 + 122 + 156)
= 720 - 639
n = 81
A= 153.9 mm sq
Formula for area is pi times radius squared
The answer is B) 1:6. If William has $1, Tim has 3 times as much, which means Tim has $3. Marie has 2 times as much as Tim which means she has $6. The ratio would be 1:6 William Marie.
<h3>Number of minutes in 3/4 of an hour is :
</h3>
<h3>n = 3/4 × 60 = 45 minutes.
</h3>
<h3>Now, If it continues to rain at that rate for 15 more minutes :
</h3><h3>
</h3><h3>So, time taken = 45 + 15 min = 1 hour.
</h3><h3>
</h3><h3>Let, rain gauge is filled x fraction in 1 hour.
</h3>
<h3>So,
</h3>
<h3>Hence, this is the required solution.</h3>
Answer: 15
Step-by-step explanation:
8 x 3 = 24
24 - 9 = 15
So, 15 + 9 = 24 divided by 3 = <u>8</u>
