Answer:

The product is usually smaller than the two numbers multiplied

Step-by-step explanation:

When we multiply two decimals less than one, it is a certainty that the result of the multiplication would be less than the two decimals that were multiplied. An example is the multiplication of the decimals below;

0.958 * 0.325

which equals 0.31135

We can see from the example above that the result of the multiplication of the two decimals that are less than one, results in a product that is less than the factors that were multiplied.

Answer:

<h2>a) x = 16 and y = 6</h2><h2>b) P = 864 in</h2>

Step-by-step explanation:

a)

The opposite sides of the rectangle are of equal length.

Therefore we have the system of equations:

\left\{\begin{array}{ccc}3y=2+x&\text{subtract 2 from both sides}\\3x=2+x+5y&\text{subtract x from both sides}\end{array}\right\\\\\left\{\begin{array}{ccc}3y-2=x&(*)\\2x=2+5y&(**)\end{array}\right

Substitute from (*) to (**):

2(3y-2)=2+5y\qquad\text{use distributive property}\\\\(2)(3y)+(2)(-2)=2+5y\\\\6y-4=2+5y\qquad\text{add 4 to both sides}\\\\6y=6+5y\qquad\text{subtract 5y from both sides}\\\\\boxed{y=6}

Put the value of y to (*):

x=3(6)-2\\\\x=18-2\\\\\boxed{x=16}

b)

Calculate the width and the length:

3x = 3(16) = 48\\\\3y = 3(6) = 18

The perimeter:

P = 2w + 2l\\\\P = (48)(18)=864\ in

If your first first oil changes 5000 miles and then every three hundred three thousand miles after if you drive your car 250 mil
LenKa [72]

Answer:

4 oil changes

Step-by-step explanation:

Given that:

Distance after first oil change = 5000 miles

Subsequent oil changes = 3300 miles

If distance in miles moved per week = 250 m

Number of weeks per year = 52

Total miles moved per year = (250 * 52) = 13000 miles

Let Number of oil change per year = n

Difference between successive oil change = d = 3300 miles

Using the relation :

Total miles = Ist change + (n - 1)d

13000 = 5000 + (n - 1)3300

13000 = 5000 + 3300n - 3300

13000 = 1700 + 3300n

13000 - 1700 = 3300n

11300 = 3300n

n = 3.424

Hence, number of oil. Changes in first year = 4
