Answer:
Unfortunately, we can't do anything with 41 as it has no factors. Since
is already simplified, try submitting that as your answer. If that doesn't work then try un-doing their steps and get rid of the 3:



Hope this helps!
To answer, determine first the length of the arc intercepted by the angle which measures 45°.
Calculate for the circumference of the circle with the equation,
C = 2πr
where C is circumference and r is radius. Substitute the known value for r,
C = 2π(7) = 43.98
Then, multiply the obtained value by the ratio of the angle intercepted and the whole revolution.
Arc = 43.98 x (45°/360°)
Arc = 5.5
The whole perimeter of the sector includes the arc and 2 radii. Hence, the equation for the whole perimeter is,
Perimeter = Arc + 2r
Substituting the values,
Perimeter = (5.5) + 2(7)
Perimeter = 19.50
<em>ANSWER: 19.50 units</em>
Ok let's start with question 1.
1. The equation is given. If she advices 360 people each week for 4 week she earns...
4(80+360(15)/100) = $536
2. In this problem instead of evaluating M we solve for n with M given.
140=80+15n/100
n=400 people
3. The new equation will still follow the same format.
M=65+21n/100
4. This will be the intersection point of the two lines. So when does...
80+15n/10=65+21n/100
We just have to solve for n.
-0.06n=-15
n=250 people
Answer:
45 km/h
Step-by-step explanation:
Speed = x, distance= 360 km
------------
- 360/x= 360/(x-5)- 1
- 360/(x-5)-360/x= 1
- 360x-360(x-5)=x(x-5)
- x^2-5x=360*5
- x^2-5x- 1800=0
- x=45 km/h
