Answer:
There are a total of 360° in any given circle, so an arc swept out by 60° of that 360° would make up 60/360 = 1/6 of the circle's circumference.
The formal for the circumference of a circle comes out of the definition of one of the most famous constants in mathematics: π. π is defined as the ratio between a circle's circumference and its diameter, or:
From this definition, we can multiply both sides of the equation by d to obtain
or, circumference is π times the diameter. To find the diameter, we just need to double the radius, giving us 5 * 2 = 10cm. Usually you'll see π approximated as 3.14, which is likely what they want you to use here. Using that approximation, we find the circumference to be 3.14 * 10 = 31.4 cm.
Finally, to get the length of that arc, we just need to take 1/6 of the circumference (since the arc sweeps out 1/6 of the circle), giving us 31.4 * 1/6 ≈ 5.2 cm.
Step-by-step explanation:
4=2+25t
We move all terms to the left:
4-(2+25t)=0
We add all the numbers together, and all the variables
-(25t+2)+4=0
We get rid of parentheses
-25t-2+4=0
We add all the numbers together, and all the variables
-25t+2=0
We move all terms containing t to the left, all other terms to the right
-25t=-2
t=-2/-25
t=2/25
plz give Brainliest
1. distribute the -8 into the parentheses and you get -32+24x-17x
2. combine like terms and get -32+7x
3. if you need to make it simpler set the equation = to zero -32+7x=0 and then add the 32 on both sides
4. 7x=32 and then divide by 7 and you get 32/7 or approximately 4.571
I hope this helped!! :)
