The equation is written below,
30.16 = 17.56 + 5x
First, subtract 17.56 from both sides of the equation,
30.16 - 17.56 = 17.56 + 5x - 17.56
This will give us 12.6 = 5x
Then, divide both sides of the equation by 5.
12.6/5 = 5x/5
Simplifying,
2.52 = x
Thus, the value of x is 2.52.
A. The wire needs to be 138.226 cm long but already 34.5565 cm of the circle has been covered.
B. To determine the length of the wire needed, we subtract a quarter of the circles circumference from its whole circumference.
Step-by-step explanation:
Step 1:
The circumference of a circle is obtained by multiplying the radius with 2π.
The circumference of a circle
Here the radius of the circle is 22 cm but already a quarter of the circumference has been covered with wire.
Step 2:
So to determine the length of the wire needed, we subtract a quarter of the circles circumference from its whole circumference.
So the circumference of the circle cm.
cm and cm.
So the wire needs to be 138.226 cm long but already 34.5565 cm of the circle has been covered. An additional 103.6695 cm of wire is needed to cover the remaining circle.
1.55x15=23.25
1.95x15=29.25
15x15=30
23.25+29.25=52.5
52.5/30=1.75

Answer:
It is D. (x + 1)^2 + (y - 3)^2 = 16.
Step-by-step explanation:
The general equation of a circle is
(x - h)^2 + (y - k)^2 = r^2 where the center is (h, k) and the radius is r.
So substituting the given values the required equation is:
(x + 1)^2 + (y - 3)^2 = 4^2.

Answer:
8 3/4 hours
Step-by-step explanation:
Time is inversely proportional to speed for the same distance. The time for 1.2 times the speed will be 1/1.2 times the given time:
(10.5 h)/1.2 = 8.75 h
It will take 8.75 hours at the increased speed.
