anastassius [24]

Answer:

a) About 48 of the shoppers, that is $230\frac{21}{100}$ of the shoppers, received a free set of earbuds.

b) About 58 shoppers, that is $\frac{230}{4}$ received $5 off their first purchase.

Step-by-step explanation:

a. About how many shoppers received a free set of earbuds?

21% out of 230. So

$230\frac{21}{100} = 2.3(21) = 48.3$

About 48 of the shoppers, that is $230\frac{21}{100}$ of the shoppers, received a free set of earbuds.

b. About how many shoppers received $5 off their first purchase?

25% out of 230, so:

$230\frac{25}{100} = 230\frac{1}{4} = \frac{230}{4} = 57.5$

About 58 shoppers, that is $\frac{230}{4}$ received $5 off their first purchase.

Perform the indicated operation (-2i+3i)+(-1-4i)

Shtirlitz [24]

Answer:

-1 -3i

Step-by-step explanation:

It is unusual to have two imaginary terms grouped together like this. Taking the question at face value, we treat i as though it were a variable, and collect terms in the usual way.

(-2i +3i) +(-1 -4i) = i(-2+3-4) -1 = -1 -3i

Given :-

x/2 = 3

To Find :-

The value of 2x + 2 .

Solution :-

The given equation to us is ,

$\longrightarrow$ x/2= 3

$\longrightarrow$ x = 3*2

$\longrightarrow$ x = 6

Now we need to find out ,

$\longrightarrow$ 2x + 2

$\longrightarrow$ 2(6) + 2

$\longrightarrow$ 12 + 2

$\longrightarrow$ 14

Hence the required answer is 14.

X2 + 5x - 14 Select one of the factors of the quadratic expression.

vfiekz [6]

The equation factored would be (x+7)(x-2). As 7-2=5 and (7)(2)=14.
