Answer:
13.0833 ft²
Step-by-step explanation:
From the question given above, the following data were obtained:
Radius (r) = 5 ft
Angle sustained by the sector (θ) = 360 – 300
= 60°
Pi (π) = 3.14
Area of sector (A) =?
The area of the sector can be obtained as follow:
A = θ/360 × πr²
A = 60/360 × 3.14 × 5²
A = 1/6 × 3.14 × 25
A = 1/6 × 78.5
A = 78.5/6
A = 13.0833 ft²
Thus, the area of the sector is 13.0833 ft²
Answer:
6%
Step-by-step explanation:
Given,
Interest (I) = 2160
Principal (P) = 12000
Time (T) = 3 yrs
Rate (R) = ?
We know that,
R = ( I *100)/ (P*T)
= (2160*100)/(12000*3)
= 6%
therefore, the rate of interest is 6%
<span>investment A has 500 (for April) + 600 (for May) + 400 (for June) with a total of 1500.
</span><span>investment B has 400 (for April) + 300 (for May) + 500 (for June) with a total of 1200
</span><span>Converting each amount to ratios gives investment A: 33%, 40%, and 27% respectively. Whereas investment B ratio is: 33%, 25%, and 42%. Hence, the largest month to month change is June.</span>
Answer:
89 degrees
Step-by-step explanation:
The angle 1 is the same as angle 3.
Angle 2 is the same as angle 4.
The sum of these four angles is 360 degrees.
We have that:
Angle 2 = Angle 4 = 7x - 14
Angle 3 = Angle 1 = 5x + 14
Finding x:
Angle 1 + Angle 2 + Angle 3 + Angle 4 = 360
2*(5x + 14) + 2*(7x - 14) = 360
10x + 28 + 14x - 28 = 360
24x = 360
x = 15
Angle 1:
5x + 14 = 5*15 + 14 = 89 degrees
