Now sort out the numbers in the numerator and those in the denominator and multiply them together.
<em><u>Numerator</u></em> 28 * 5280 * 1 * 1 = 147840
<em><u>Denominator:</u></em> 60 * 60 = 3600
Now divide the numerator by denominator
Answer = 147840 / 3600 = 41.1 Feet / second
28 miles per hour = 41.1 feet / second
Answer: number 1
Step-by-step explanation:
number 1
Using the Pythagorean theorem:
Length of wire = sqrt(34^2 + 8^2)
Length of wire = sqrt(1156 +64)
Length of wire = sqrt(1220)
Length of wire = 34.9285 feet
There are 2 wires:
34.9285 x 2 = 69.857 feet
Round off as needed.
(d): y=2-4x
P(0;y) belongs to (d)
=> y=2-4*0
= 2
So P(0;2)
Q(x;0) belongs to (d)
=> 0=2-4*x
<=> x=1/2
So Q(1/2;0)
The use of ratio language was used in the following sentences:
For every 1 students out of school, there are 10 students in school
For every 5 apples John eats, he eats 20 boxes of chocolate
For every 5 minutes, study, I sleep for 1 hour
Ratio is used to show the relationship that exists between numbers. It shows the frequency of the number of times that value of one number is contained within the value of another number or numbers
For example, There are 3 apples and 20 oranges. If I want to express the relationship between apples and oranges as a ratio. The ratio will be 3 : 20 . It means for every 3 apples, there are 20 oranges.
