Answer:
6 years 4 months
Step-by-step explanation:
2 yrs+3yrs=5+1= 6
6m+10m= 16
There are 12 months in a year so 16-12=4. Add 1 more year to 5 and your left with 4 months.
Answer:10
Step-by-step explanation: substitution = 2(25-10)/3
25-10 =15
15*2=30
30/3=10
Answer =10
This is where the question tricks you, you have to make it even for us to find out the integer. So that 199 would turn into a 200.
And the integer between 1 and "200" would simply be 99.
Answer:
73.4 cm^2
Step-by-step explanation:
The equation is :
πr^2
Substitute the radius in:
π(5)^2
Solve:
Area of full circle = 25π
(Note : leave this answer in terms of 'pi' so it is easier to handle
Next, find the area of the sector
The equation for this is:
(angle/360) x πr^2
Substitute the values in:
(80/360) x π(5)^2
Solve :
Area of sector = (50/9)π
Now, find the area of the triangle:
1/2 absinC
Substitute the values in:
1/2(5)(5) x sin(80) = 12.31009691
Subtract this answer from the area of the sector
Answer = 5.14319607
Subtract this from the area of the whole circle
Answer = 73.39662073
To the nearest tenth, that would be 73.4 cm^2
