In a recipe for fizzy grape juice, the ratio of cups of sparkling water to cups of grape juice concentrate is 3 to 1. a) Find tw

Verizon [17]

Answer:

$6:2,\,9:3$

Step-by-step explanation:

Given: The ratio of cups of sparkling water to cups of grape juice concentrate is $3:1$ in a recipe for fizzy grape juice.

To find: two more ratios of cups of sparkling water to cups of juice concentrate that would make a mixture that tastes the same as this recipe

Solution:

Equivalent ratios are the ratios that have the same value.

Find two ratios equivalent to $3:1=\frac{3}{1}$

Multiply both numerator and denominator of $\frac{3}{1}$ by 2

$\frac{3(2)}{1(2)} =\frac{6}{2}$

Multiply both numerator and denominator of $\frac{3}{1}$ by 3

$\frac{3(3)}{1(3)} =\frac{9}{3}$

So, two more ratios of cups of sparkling water to cups of juice concentrate that would make a mixture that tastes the same as this recipe are $6:2,\,9:3$

Tamara purchased 1,500 shares of a mutual fund at an offer price of $7.08 per share. Later she sold the investment for $10.02 pe

den301095 [7]

Answer:

Return of investment = 44.5%

Step-by-step explanation:

Number of shares purchased by Tamara = 1500

Offer price per share = 7. 08

Total amount spent on purchasing shares = 1500 × 7.08 = 10620

Dividend receive per share = 0.21

Total dividend received on 1500 shares = no. of shares × dividend received per share

Total dividend received = 1500 × 0.21 = 315

Selling price per share = 10.02

Amount received by Tamara by selling the investment = no. of shares × selling price per share

Amount received by Tamara by selling the investment

= 1500 × 10.02

= 15030

Now, Net profit received on investment = S.P of Investment + Dividend received - C.P of investment

Net profit = 15030 + 315 - 10620 = 15345 - 10620 = 4725

Return on investment = $\frac{Net\ profit}{Cost\ of\ investment} \times 100$

= $\frac{4725}{10620} \times 100 = 44.49%$

≈ 44.5 %

Solve: S = n/2 (a+b) for b

IgorC [24]

Answer:

b = -n/(2-S) -a

Step-by-step explanation:

S = n/2 (a+b)

divide both sides by (a+b)

S/(a+b) = n/2

flip the equation on the left (it is the same equation just negative)

-(a+b)/-S = n/2

divide both sides by -S

-a-b = n/(2-S)

add a to both sides

-b = n/(2-S) +a

flip the sign (multiply/divide by -1)

b = -n/(2-S) -a

This match could be

3x0 D or F

3x1 D or F

3x2 D or F

For 3x0

We have 2 options: DDD or FFF

2.P₁ = 2.1 = 2

For 3x1

We have 6 options

DFDD FDFF

DDFD FFDF

FDDD DFFF

2.3.1 = 6

For 3x2

we have 12 options:

DFDFD FDFDF

DDFFD FFDDF

DFFDD FDDFF

FFDDD DDFFF

FDFDD DFDFF

FDDFD DFFDF

2.3.2 = 12

In total we could have 20 outcomes.
