pentagon [3]

Answer:

Correct choce is (a). 30.

Step-by-step explanation:

Given equation is $f(x)=x^2-x$ .

Now we need to find the value of (fof)(3). Then select correct matching choice from the given choices. Where given choices are:

(a). 30

(a). 33

(a). 6

(a). -6

Now let's find $(fof)(3)$

$(fof)(3)=f(f(3))$

$(fof)(3)=f(3^2-3)$

$(fof)(3)=f(9-3)$

$(fof)(3)=f(6)$

$(fof)(3)=6^2-6$

$(fof)(3)=36-6$

$(fof)(3)=30$

Hence correct choce is (a). 30.

Kisachek [45]

Answer:

Number of ripe mangoes were sold as 132

Step-by-step explanation:

Let's assume number of rip mangoes were sold as 'x'

A store manager ordered 28 crates of mangoes

Number of crates =28

There were 36 mangoes in each crate

Number of mangoes in each crate=36

Total number of mangoes=( Number of crates)*(Number of mangoes in each crate)

Total number of mangoes is

$=28\times 36$

$=1008$

WHEN the mangoes were delivered

he sold the ripe mangoes and repacked the rest equally into 73 boxes

There were 12 mangoes in each box

Total number of mangoes is

$=73\times 12+x$

$=876+x$

now, we can set them equal

$1008=876+x$

$x=132$
