Answer:
Raquel should adjust the number of rotations to 115.81 rotations
Step-by-step explanation:
step 1
Find the circumference of the wheels that are 2.5 cm in diameter
The circumference is equal to

we have

assume

substitute


step 2
Find the number of rotations
Divide 10 meters by the circumference


step 3
For a diameter of 2.75 cm find how should she adjust the number of rotations so that the robot travels the same distance
Find the circumference of the wheels
The circumference is equal to

we have

assume

substitute


step 4
Find the number of rotations
Divide 10 meters by the circumference


Answer:
145 . this is because angles on a straight line add up to 180 degrees
Answer:
105.12 ft^2
Step-by-step explanation:
Area of a rectangle: bh
In this case 8*10.... so area of the rectangle is 80
Area of a circle: pir^2
Half it for a semicircle.
so 1/2 pi r^2
radius is 4 cuz its half of 8.
so 1/2(3.14)(4^2)=(0.5)(3.14)(16)=25.12
Now add up 80+25.12
Total is 105.12
Hope I helped :)

Answer:

Step-by-step explanation:
The given equation is :
N=S(P-V)-F ...(1)
We need to solve the above equation for S.
Adding F both sides in equation (1)
N+F=S(P-V)-F+F
N+F=S(P-V)
Dividing both sides by (P-V). So,

So, the above is the expression for S.
