Answer:
1.125 h = 1h 7.5 min = 1 h 7 min 30 sec
Step-by-step explanation:
John makes 1/1.5 work per h.
His partner makes 1/4.5 work per h.
Together they make (1/1.5 + 1/4.5) = (3/4.5 + 1/4.5) = 4/4.5 work per h.
They will work
1 : 4/4.5 = 4.5/4 = 1.125 h = 1 h + 0.125 h = 1h + 0.125h*60min/1h =
=1h 7.5 min = 1 h 7 min 30 sec
X = first place....and each place after that is 50 less
so 2nd place would be x - 50 and third place would be x - 100
so ur answers are :
b. x + (x - 50) + (x - 100)
f. 3x - 150 ...u get this when u combine like terms
Based on the graph, the slope is -3, and the y-intercept is 1. So your equation should be:
y = -3x + 1
The answer is C
y + 2 = -3(x - 1)
y + 2 = -3x + 3
y = -3x + 1

Answer:
113.142857 m²
Step-by-step explanation:
As per the provide information in the given question, we have :
- Radius of the circular ground = 6 m
We are asked to find the area of the ground.
Since, it is in the shape of circle, so we'll apply here the formula to find the area of the circular ground.
We know that,
>> Area of circle = πr
>> Area of the ground =
× 6 m × 6 m
>> Area of the ground =
× 36 m²
>> Area of the ground =
m²
>> Area of the ground = 113.142857 m²
<u>Therefore</u><u>,</u><u> </u><u>area</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>ground</u><u> </u><u>is</u><u> </u><u>113.142857 m²</u><u>.</u><u> </u>
