Answer:
Step-by-step explanation:
1. let x be the unknown number.
-Given that 24 divided by x is less than x is less than 7 means that 7 is greater than the quotient thereof.
-The in equality is written as:
2.Let the amount Chris has be y.
-At most is a term of inclusivity implying less than or equal to a specified quantity.
-$5 less than twice y will therefore be represented as:
3. It is clear that the minimum age to have a drivers license is 16.
-Let x be the age of a driver whose age is unknown.
-It is therefore obvious that all drivers in Ohio are either exactly 16 years or older.
-Our inequality symbol is that of equal to or greater than, thus:
4. let x be the number of CD's bought and y of DVD's bought.
-CD's are priced at $14 each and DVD's at $16 each, given a budget of $65.
-They can only buy a number of units whose price is less than or exactly $65, thus:
Equation of shaded triangle is .
Solution:
Length of the rectangle = 14 ft
Breadth of the rectangle = 8 ft
Area of the rectangle = length × breadth
= 14 × 8
In this rectangle the diagonal splits the rectangle into two equal halves.
Area of the shaded triangle = Half of area of rectangle
Area of the shaded triangle =
Hence the equation can be used to calculate the area of the shaded
triangle is .
