Answer:

Step-by-step explanation:

Steps to solve "54 is 90 percent of what number?"

We have, 90% × x = 54

or,

90/100 × x = 54

Multiplying both sides by 100 and dividing both sides by 90,

we have x = 54 × 100/90

x = 60

If you are using a calculator, simply enter 54×100÷90, which will give you the answer.

You wish to purchase a new car and can afford monthly repayments of up to $250 per month. You see a car you like for $12,000 and

White raven [17]

Answer:

Since the finance’s monthly required payment of $304.07 is greater than the $250 monthly that you can afford, this implies that you CANNOT afford to purchase the car on finance.

Step-by-step explanation:

The monthly required payment of the finance can be calculated using the formula for calculating the present value of an ordinary annuity as follows:

PV = M * ((1 - (1 / (1 + r))^n) / r) …………………………………. (1)

Where;

PV = Present value or finance amount = $12,000

M = Finance’s monthly required payment = ?

r = Monthly interest rate = Annual interest rate / 12 = 17.9% / 12 = 0.179 / 12 = 0.0149166666666667

n = number of months = Number of years * 12 = 5 * 12 = 60

Substitute the values into equation (1) and solve for M, we have:

$12,000 = M * ((1 - (1 / (1 + 0.0149166666666667))^60) / 0.0149166666666667)

$12,000 = M * 39.464764662266

M = $12,000 / 39.464764662266 = $304.07

Since the finance’s monthly required payment of $304.07 is greater than the $250 monthly that you can afford, this implies that you CANNOT afford to purchase the car on finance.

A blacksmith blends one alloy of silver that is 35% silver and another that is 95% silver. To the nearest ton, how much of the a

hammer [34]

Answer:

Let x be the unknown quantity of 50% silver.

Look at the silver concentrations... This will be 0.5x of actual silver,

Added to 5% silver in 500g or 0.05(500)g of actual silver

Totaling to (500+x)g of 20% silver which will have 0.2(500+x)g of silver

Your equation is:

0.5x + 0.05(500) = 0.2(500+x)

Solve for x to find the grams of 50% silver used

All of number one thank you

Vadim26 [7]

I'm going to divide number one to 6 parts
1. $\frac{4}{10}$ = $\frac{40}{100}$
2. $\frac{7}{10}$ = $\frac{70}{100}$
3. $\frac{2}{10}$ = $\frac{20}{100}$
4. $\frac{9}{10}$ = $\frac{90}{100}$
5. $\frac{18}{10}$ = $\frac{180}{100}$
6. $\frac{26}{10}$ = $\frac{260}{100}$

because to make the denominator to 100, you need to multiply 10 by 10 which is 100.
and because you multiply 10, you also have to multiply the numerator by 10.
EXAMPLES: $\frac{3}{10}$ = $\frac{3}{10}$ × $\frac{10}{10}$ = $\frac{30}{100}$
