Answer:
28.25 million
Step-by-step explanation:
Population of the country:
- in 2001 - x million
- in 2006 - 30.4 million
Population of the country as percent:
- in 2001 - 100%
- in 2006 - 100% + 7.6% = 107.6%
Write a proportion:
Cross multiply:
Divide by 107.6:
Using the compound interest formula,
A = P(1+r)^n
A = 17000
r = 4% quarterly
n = 8yrs = 32 quarters of a year
P = ?
17000 = P(1+4%)^32
P = $[17000/((1+4%)^32)]
Answer:
<em>y=-6</em>
Step-by-step explanation:
<u>Proportions</u>
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
Substituting x=-3 y=9:
9 = k(-3)
Now the relationship is:
y = -3x
For x=2
y = -3(2) = -6
Answer:
√19 or 4.36
Step-by-step explanation:
Since one leg is missing, you need to use Pythagorean theorem for this.
The hypotenuse is known so,
c² - a² = b²
c = 10
a = 9
b = ?
10² - 9² = b²
100 - 81 = b²
19 = b²
b = √19
Answer:
$59
Step-by-step explanation:
There is a discount of $3 on price of shirt and jeans [both]
Shirt (per unit cost):
Before Discount: $12
After Discount: $12 - $3 = $9
Jeans (pair cost):
Before Discount: $19
After Discount: $19 - $3 = $16
Pani wants to buy 3 shirts and 2 pair of jeans. So her cost would be:
59 dollars.
