A composite number because other digits go it besides itself and one
Step-by-step explanation:
area=length x width
91=(x+2)(2x+3)
91=x^2+5x+6
x^2+5x-85=0
x=14.2 orx=-24.1
We know that Marcus spent 10 hours on his homework this week so:
10 hours = 100%
Marcus is saying that he spent 110% more time doing his homework this week, in comparison to last week.
Then to see if he is correct we have to find 110% of 10 hours.
So if: 100% of 10 hours = 10 hours
And: 10% of 10 hours (equivalent to 600 minutes) = 1 hour (or 60 minutes)
Then we add the two: 10 hours + 1 hour
And we get: 11 hours
As a result, Marcus is correct; he did spend 110% more time on his homework this week.
Hope this helps! :D
Answer:
204.2 units
Step-by-step explanation:
Area of semicircle: 1/2(πr^2)
r = 5
1/2(π(5)^2)
94.2477796
Area of Rectangle: w * l
l = 11
w = 5(2)
11 * 5(2) = 11 * 10 = 110
Total:
110 + 94.2 = 204.2 units
By the scale of 1:1000, it implies that ; 1cm on the map represents 1000 on actual ground.
So 2.5cm will represent 2.5×1000=2500
