A number decreased by 24 is -1

prohojiy [21]

Answer:

Step-by-step explanation:

The word decreased indicates the use of subtraction, so to figure out our answer we do the opposite, -1 + 24 = 23, after that we then subtract, 23 - 24 = -1, there for your answer should be 23 - 24 = -1, or more simply the number that has to be decreased to make the statement true is 23

LiRa [457]

Answer:

A = 907.46 $m^{2}$

C = πd

34π = πd

d = 34

r = 17

A = $\pi r^{2}$ = 3.14( $17^{2}$ ) = 3.14(289) = 907.46 $m^{2}$

Find the complement of the set given that

natima [27]

The complement of the set is {8, 9, 10, 11}

<h3>How to find the complement of the set?</h3>

The universal set is given as:

U = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11}.

The other set is given as:

{x | x is in N and x < 8}

The complement of the set is the set elements that are in the universal set, but not in the given set

The set {x | x is in N and x < 8} can be rewritten as

X = {0, 1, 2, 3, 4, 5, 6, 7}

So, the complement is

X' = {8, 9, 10, 11}
