A rectangle or table top has a length of 4 3/4 feet in an area of 11 7/8 ft.² what is the width of the table top

1 answer:

7 0

If the length of the tabletop is 4 3/4 and the area is 11 7/8, then the width of the table top is 2 1/2.

To come up with this, you simply use the formula w=a/l to find the width.
w=11 7/8 / 4 3/4=2 1/2.

Select either relation (if the set is a relation but not a function), function (if the set is both a relation and a function), o

galina1969 [7]

Answer: The correct options are

(A) relation

(B) function.

Step-by-step explanation: We are given to check whether the following set is a relation or a relation and a function or neither :

A = {(1, 2) (2, 2) (3, 2) (4, 2)} .

Let us consider the following two sets :

U = {1, 2, 3, 4} and V = {2}.

Then, we see that the Cartesian Product of U and V is given by

U × V = {(1, 2) (2, 2) (3, 2) (4, 2)}.

Since a relation is a subset of Cartesian product, so the given set A is a relation.

Also, we know that a relation is a function if every first element is associated with one second element.

Since the relation A satisfies this condition, so the relation A is a function.

Thus, the given set A is both a relation and a function.

Option (A) and (B) are correct.

The population of a town doubled every 5 years from 1960 to 1975. What is the percentage increase in population in this period ?

777dan777 [17]

Answer:

Step-by-step explanation:

Let p represent the population

in 1965 → the population becomes 2p

in 1970 → the population becomes 2(2p) = 4p

in 1975 → the population becomes 2(4p) = 8p

p ——————> 100%

8p ————-—-> x%

then

$x=\frac{8p*100}{p}=800$

Determine, in degrees, the measure of each interior angle of a regular octagon

Harman [31]

Answer:

Each interior angle = 135 degrees,

Step-by-step explanation:

The exterior angles of all convex polygons add up to 360 degrees.

So for a regular octagon each exterior angle = 360 / 8

= 45 degrees.

Therefore each interior angle = 180 - 45 = 135 degrees,
