What is Arc?An "arc" in mathematics is a straight line that connects two endpoints. An arc is typically one of a circle's parts. In essence, it is a portion of a circle's circumference.
A curve contains an arc. A circle is the most common example of an arc, yet it can also be a section of other curved shapes like an ellipse.
We have,
The top of the easel forms a 30° angle and m (BC) = 22°.
As per the question,
AD = ED and m<O = 30
So, m <OAE = m <OEA
= 1/2 (180 - m<D)
= 75
and, m <BEC = 1/2 (m BC)
= 1/2(22)
= 11
Then, m<BEA = m <OEA - m <BEC
= 75 - 11 = 64
Also, m (AB) = 2 x 64 = 128

Answer:
rate: 24:2
unit rate: 12:1
Step-by-step explanation:
Given function:
24 inches in 2 feetto find the rate and unit rateWhat is the rate?:
24 inches would be the first digit and 2 feet would be the second one..
the rate would be 24:2..
What is the unit rate?:
unit rates would be the lowest form which means that you have to find a equivalent factor to find the unit rate..
24*2=12, 2*2=1
this also means 12:1
Therefore, the rate of 24 inches and 2 feet is 24:2 and the unit rate would be 12:1.

The power, P (watts) , of a car engine is proportional to the square of its speed, s ( m / s ) . When s = 30 , P = 1260 . Work out the power when the speed is 25 m / s
Answer:
875 Watts
Step-by-step explanation:
Given that :
P α s²
P = ks²
Where k is the proportionality constant
When ; p = 1260 ; s = 30
1260 = k * 30²
1260 = 900k
k = 1260 / 900
k = 1.4
Value of p ; when s = 25
P = 1.4 * s²
P = 1.4 * 25²
P = 1.4 * 625
P = 875 watt

How many times larger is 6*10^ 7 than 3*10^ 6 ?
Answer:
20
Step-by-step explanation:
step 1: Evaluate the expressions
6*10^7 = 60,000,000
3*10^6 = 3,000,000
step 2: Devide
60,000,000 / 3,000,000 = 20
so 60,000,000 is 20 times larger than 3,000,000
