Answer:
10.99 feet
Step-by-step explanation:
The arc length when an angle of 360° is made is the perimeter of the circle.
Perimeter = π*Diameter = π*30 = 94.25 ft
To know the arc length when an angle of 42° is made, we need to use the following proportion
94.25 ft / x ft = 360° / 42°
x = 42/360*94.25
x = 10.99 ft
Answer:
$24.09
Step-by-step explanation:
you do 984.20-381.80=602.4
then divide 602.4 by 1/4
which 1/4=25.
then you get $24.09
umm ,this is too long could you maybe putt it in smaller form so I can answer
Answer:
Malik substituted 60 for y instead of x.
Step-by-step explanation:
According to the given situation the computation of error that Malik make first when solving the equation is shown below:-
First, we will find the value of x



x = 625
Now, we have

we will solve the above equation, to find the value of y
24 - 4y = 10
4y = 24 - 10
4y = 14


So, from the above calculation, the correct option is
Malik substituted 60 for y instead of x.
Divide the miles he traveled by the time it took him to travel it.
22 1/2 / 1/3
Multiply by the reciprocal of 1/3:
22 1/2 * 3/1
Convert 22 1/2 into an improper fraction:
45/2 * 3/1
Multiply the numerators and denominators together:
135/2
Divide:
67.5 or 67 1/2
So his average speed in miles per hour is 67 1/2.
