Answer 1

Answer:

Answer:

x = 14

BE = 6

Step-by-step explanation:

to find 'x': BG = 1/2[(x-9) + (3x-13)]

BG = 4x-22 / 2

BG = 3x-25

3x-25 / 1 = 4x-22 / 2

cross-multiply:

4x-22 = 2(3x-25)

4x-22 = 6x-50

-2x = -28

x = 14

to find 'BE': CB = BE

2x+4 = 7x-1

-5x = -5

x = 1

BE = 7(1) - 1

BE = 6

If 40% of the total population of a particular town of 2500 are HIV positive. How many people are HIV negative.

Answers

Answer:

1500 people

Step-by-step explanation:

Since 40% are HIV positive (that's a lot of people), 60% will be HIV negative. All you have to do is find 60% of 2500.

60% of 2500 = 0.6 * 2500 = 6 * 250 = 1500

8,240,000

Answer:

Option 3 - $8.24* 10^6=8,240,000$

Step-by-step explanation:

Given : Number - $8.24* 10^6$

To find : Re-write the number into standard notation?

Solution :

Standard notation in the expansion of scientific notation.

Scientific notation $8.24* 10^6$

$10^6$ means 10 with 6 zeros i.e. 1000000

So, $=8.24* 1000000$

Removing decimal,

$=(824)/(100)* 1000000$

$=824* 10000$

$=8240000$

Therefore, $8.24* 10^6=8,240,000$

So, Option 3 is correct.

The equation D=13/v shows that the density of a particular substance equals a mass of 13 grams divided by the volume of the substance. What happens to the density as the volume approaches 0?The density approaches infinity.
The density approaches 0.
The density approaches 1.
The density approaches 13.

Answers

For this case we have the following equation:
$D = (13)/(v)$
Where,
D: the density of a particular substance
v: the volume of the substance
When replacing v = 0 in the given equation we have:
$D = (13)/(0)$
$D = \infty$
This means that as the function acquires values very close to zero, the density acquires a very large value.
Answer:
as the volume approaches 0:
The density approaches infinity.
option 1

As the volume approaches 0,
The density approaches infinity

The graph of the equation is a hyperbola with the asymptote at v = 0. This means that when the value of v is very close to 0, the value of the density is very large.

On August 8, 1981, American Savings offered an insured tax-free account paying 23.24% compounded monthly. If you had invested $90,000 at that time, how much would you have on August 8, 2014, assuming that you could have locked the interest rate at the time of deposit? Someone please help me!!

Answers

Answer:

$181,432,754

Step-by-step explanation:

We use the formula for compound interest here, to determine the amount

Mathematically, that would be;

A =I (1 + r/n)^nt

where A is the amount which we want to calculate

I is the initial amount which is $90,000

r is the rate = 23.24% = 23.24/100 = 0.2324

n is the number of times per year the interest is compounded = 12 (compounded monthly)

t is the number of years = 2014 - 1981 = 33

Substituting these values, we have;

A = 90,000(1 + 0.2324/12)^(33 * 12)

A = 90,000(1 + 0.0194)^396

A = 90,000(1.0194)^396

A = 181,432,754.27210504

Which is approximately $181,432,754 to the nearest whole dollars

The functions f(x) and g(x) are shown below:f(x) = 0.05x
g(x) = (0.05)x
Which statement best describes the graph of f(x) and g(x)?

Answers

f(x) and g(x) are two functions each representing data points. We can see from the given function both of the functions are equal because both have a value of 0.05x. If you evaluate the equation with a given x value, we will observe that the answer for both functions is the same.

This is the best answer that I can give you. The graphs will both have their y-intercept equal to 0.05
