Multiply each set of numbers and match it with it’s product

Fynjy0 [20]

Answer:

1. $1. (\frac{5}{16}) (-2) (-4) (\frac{-4}{5})= -2 \\2. (2\dfrac{3}{5}) (\frac{7}{9})=(\frac{91}{45})\\3. (\frac{2}{3})(-4)(9)= -24\\4. (\frac{-3}{4}) (\frac{7}{8})=(\frac{-21}{32})$

Step-by-step explanation:

These are simple multiplication questions of fractions. We multiply numerator with numerators and denominators with denominators. If numerator and denominator is both divisible by same number we can divide them for simplification.

1. $(\frac{5}{16}) (-2) (-4) (\frac{-4}{5})$

$=(\frac{-10}{16}) (-4) (\frac{-4}{5})\\=(\frac{40}{16}) (\frac{-4}{5})\\=(\frac{-160}{80}) \\dividing\,\, numerator\,\, and\,\, denominator\,\, by\,\, 80\,\,\\= -2$

2. $(2\dfrac{3}{5}) (\frac{7}{9})$

Converting mixed form into fraction form,

$=(\frac{13}{5})(\frac{7}{9})$

Multiplying numerators with each other and denominators with each other

$=(\frac{13*7}{5*9})\\=(\frac{91}{45})$

3. $(\frac{2}{3})(-4)(9)$

Multiplying these terms with each other:

$=(\frac{2*-4}{3})(9)\\=(\frac{-8}{3})(9)\\=(\frac{-8*9}{3})\\=(\frac{-72}{3})\\$

Dividing numerator and denominator with 3

$=-24$

$4. (\frac{-3}{4}) (\frac{7}{8})\\=(\frac{-3}{4}) (\frac{7}{8})\\=(\frac{-3*7}{4*8})\\=(\frac{-21}{32})$

An investment project involves an immediate outlay of $8 million. The net cash flows received at the end of years 1, 2, and 3 wi

My name is Ann [436]

Answer:

(c) 0.46 million

Step-by-step explanation:

As provided immediate cash outlay = $8 million.

This will represent cash outflow at period 0, as it is made immediately, no time period has lapsed.

Cash inflows as provided and the respective present value factor are:

Year Cash Inflow Factor Discounted Value

1 $3 million 0.9091 $2,727,300

2 $4 million 0.8264 $3,305,600

3 $2 million 0.7513 $1,502,600

Total present value of cash inflow = $7,535,500

Therefore, net present value = $7,535,500 - $8,000,000 = - $464,500

That is - 0.46 million

Correct option is

(c) 0.46 million

Noah has 5 pieces of bubble gum to share with his 5 teammates. He wants to give each teammate the same number of pieces. How man

Talja [164]

Answer:

1 each

Step-by-step explanation:

Given that Noah has 5 pieces of bubble gum

There are 5 teammates of Noah.Noah wants to share the 5 pieces among 5.

Since there are exactly 5 pieces and there are 5 team mates, the no of piece that can be given to each team mate =1

So if 1 piece is given to teammate, there will be equal distribution of bubble gum pieces to all 5 team mates.

Verify:

If 1 is given to each of 5 teammates, the number of bubble gum pieces required =5

This is equal to the no of pieces Noah has.

During a sale at a bookstore, a customer buys one book at full price. The customer is given a 25 percent discount on a second bo

RoseWind [281]

Amount paid for the first book is $17.

Amount paid for the second book is 0.75 x 8 = $6

Total amount paid = $17 + $6 = $23

Total full cost of the two books = $17 + $8 = $25

Amount of discount = $25 - $23 = $2

% reduction = $\frac{2}{25} \times100\%=8\%$

Therefore, the <span>percent of the total cost of the two books reduced during the sale</span> is 8%
