1. 1 hour is 3x20 minutes so distance is 3 km wi=hich is 3000 metres
2. same way as before but now 4x 1km is 4000 metres, minus the previous answer is 1000 metres.
3. 26 days x 24 hours (in one day) = 624 hours
4. A) 1 hour 45 minutes
B) 10:10, because add one hour and then minus 10 minutes (probably easiest way)
The answer is 5 (C)
This is because the triangle is an isosceles triangle meaning that both MN and ML are the same length and "5" would make them both 15.
Answer:
The perimeter of crater lake is 17.27 miles.
Step-by-step explanation:
Given as :
The shape of the lake is like a circle
The diameter of lake = d = 5.5 miles
∵ shape pf lake is circle, so the diameter of circle = d = 5.5 miles
Let The perimeter of crater lake = p miles
<u>Now, As we know</u>
The perimeter of circle = 
× diameter
the value of = 3.14
Or, p = × d
Or, p = × 5.5 miles
Or, p = 3.14 × 5.5 miles
∴ p = 17.27 miles
So, The perimeter of circle = perimeter of lake = p = 17.27 miles
Hence, The perimeter of crater lake is 17.27 miles. Answer
Answer:
x=17
Step-by-step explanation:
7x+15=4x+66
3x=51
x=17
Assume L=1.5W, where W=width, L= Length of the triangle.
Therefore,
Perimeter (P) = 2(W+L) = 2(W+1.5W) = 2(2.5W) = 5W=20 => W=20/5 = 4 in
Then, L=1.5W = 1.5*4 = 6 in
Area, A= L*W = 6*4 = 24 in^2
