Answer: it has 900,000 more aliens than planet Zamba.

Step-by-step explanation:

Planet Ruba has 1,000,000 aliens.

Planet Zamba has 100,000 aliens.

first, the difference is:

1,000,000 - 100,000 = 900,000

this means that planet Ruba has 900,000 more aliens that planet Zamba.

and the relation comes from:

population of Ruba/population of Zamba

1,000,000/100,000 = 10

this means that planet Ruba has 10 times the amount of aliens that planet Zamba has.

A set of furniture was sold for GH cedis 3000 at a profit of 25%. Find the cost price.
Sindrei [870]

Answer:

<h2>2400GH Cedis </h2>

Step-by-step explanation:

Selling \:price = 3000gh Cedis\\Profit \% = 25\%\\Cost\:price =?\\\\CP =\frac{ ( Selling\:price \times 100 )}{ ( 100 + percentage profit)}  \\\\C.P = \frac{3000\times 100 }{100+25}\\\\ C.P = \frac{300000}{125} \\\\Cost\: Price = 2400gh Cedis

I'm not really looking for an exact answer, I'm more so looking for an explanation on how to do this.

I would have each block be 1/6 of a yard

You could technically have any value you want, but for me 1/6 is easiest because 1/2 and 1/3 will scale up to this like so

1/2 = (1/2)*(3/3) = 3/6

1/3 = (1/3)*(2/2) = 2/6

The diagram below might help if you're still stuck on why I picked 1/6.

The sale price of a spring break vacation package was $209.99 the travel agent said by booking early you saved $20.00. Find the
prisoha [69]

Answer:

<em></em>\%\ decrease =  9.52\%<em></em>

<em></em>

Step-by-step explanation:

Given

Sales\ Price = \$209.99

Saved = \$20.00

Required

Determine the %decrease

First, we need to determine the amount paid

Amount = Sales\ Price - Amount\ Saved

Amount = \$209.99 - \$20.00

Amount = \$189.99

The percentage decrease is the calculated as follows:

\%\ decrease = -100\% * \frac{Final - Initial}{Initial}

In this case;

Initial = Sales\ Price = \$209.99

Final = Amount\ Paid = \$189.99

So; we have:

\%\ decrease = -100\% * \frac{189.99 - 209.99}{209.99}

\%\ decrease = -100\% * \frac{-20}{209.99}

\%\ decrease = 100\% * \frac{20}{209.99}

\%\ decrease =  \frac{2000\%}{209.99}

\%\ decrease =  9.52426306015\%

<em></em>\%\ decrease =  9.52\%<em> (Approximated)</em>

A science teacher has a supply of 5% hydrochloric acid and a supply of 65% hydrochloric acid(HC1). How much of each solution sho
Sphinxa [80]
Assume that the amount needed from the 5% solution is x and that the amount needed from the 65% solution is y.

We are given that, the final solution should be 42 ml, this means that:
x + y = 42 ...........> equation I
This can also be written as:
x = 42-y .......> equation II

We are also given that the final concentration should be 45%, this means that:
5% x + 65% y = 45% (x+y)
0.05x + 0.65y = 0.45(x+y)


We have x+y = 42 from equation I, therefore:
0.05x + 0.65y = 0.45(42)
0.05x + 0.65y = 18.9 .........> equation III

Substitute with equation II in equation III as follows:
0.05x + 0.65y = 18.9
0.05(42-y) + 0.65y = 18.9
2.1 - 0.05y + 0.65y = 18.9
0.6y = 18.9 - 2.1
0.6y = 16.8
y = 28 ml

Substitute with y in equation II to get x as follows:
x = 42-y
x = 42 - 28
x = 14 ml

Based on the above calculations:
amount of 5% solution = x = 14 ml
amount of 65% solution = y = 28 ml
The correct choice is:
The teacher will need 14 mL of the 5% solution and 28 mL of the 65% solution.
