Answer:
The perimeter is 220 , the area should be 100 ,
Step-by-step explanation:The perimeter of the square is 40 because it’s all sides added together & they are all even - The perimeter of a circle is always 360 and this is half of a circle so that is a perimeter of 180; you add that to 40=220. The area is two sides multiplied together=100 for the square. You find the area of the half circle by doing the area of a circle divided by 2.
Answer:
Yep ur correct!
Step-by-step explanation:
The first one represents the numbers decreasing by a factor of 4 and the 2nd represents it of -10. C is not geometric because it is decreasing by 2 each time in which it would be arithmethic
F = (5/9)c + 32
F - 32 = (5/9)c
9(F-32) = 5c
(9(F-32))/5 = c
Answer:
6 hours
Step-by-step explanation:
To start this, you must use an equation that models the amount that Mathew and Melanie made based on time. The total amount of money earned by the two of them is 120, and they both work for 8 dollars and hour, and Mathew worked 3 more hours, our equation is 120 = 8x +8(x+3)
We must first solve for x
120 = 8x + 8x +24
-24 -24
96 = 16x
x = 6
x is the amount of hours Melane worked.
Answer:
Step-by-step explanation:
The value of t must not be one that makes the denominator zero, hence must not be 8.
