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

The expression 3(r/t) "the quotient of three times a number, and 7 option (C) 3(r/t) is correct after applying the arithmetic operation.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
It is given that:
The expression is:
The quotient of three times a number and 7
Let the two numbers be r and t:
On division:
= r/t
= 3(r/t)

Answer:
a, 4 the power of 3
b,3 the power of 12
c, 5 the power of 31
Step-by-step explanation:
a. prime factorization of 64 is 4^3
b. 2.6=12 so it became 3^12
c. prime factorization of 125 is 5^3 then 7.4 =28
so 5^3 . 5^28 = 5^31

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.
