What is the answer for this
1/2x(4/3-1/6)+3/4??

Answer:

See below

Step-by-step explanation:

π, pronounced as pi is the ratio between 2πr which is circumference to 2r which is diameter.

In word, π is circumference/diameter which has exact value of 3.14159... and it is also an irrational number too.

π is often used to be defined as 3, 3.14 or 22/7 [Keep in mind, these numbers are only approximation.] in some fields. In trigonometry, π is mostly used to refer as π radians or π rad which is equivalent to 180°.

Why do we need it? Because it’s useful in a field that requires rotation. If you notice, figure with circular base will always have π with it, the volume is an example.

In calculus, you need π to do solid of revolution method which is:

\(\displaystyle \large{V =\pi \int\limits^a_b {[f(x)]^2} \ dx }\\\\\displaystyle \large{V = \pi \int\limits^a_b {[g(y)]^2} \ dy}\)

In trigonometry, you need it for measurement/angle.  

So anything that’s related to revolution, rotation or related to circle must require π at least.

In general life, you do not use it but this is mostly applied in engineering field and anything related to science that involves with circle or revolve.

Let me know if you have any questions!

it is not a universal rule that the sum of two repeating decimals will always be a repeating decimal. There are instances where their sum can result in a terminating decimal or an integer, as demonstrated in the examples above.

It is not always true that the sum of two repeating decimals must be a repeating decimal.

There are cases where their sum can result in a terminating decimal or even an integer.
Let me provide you with a step-by-step explanation:
Firstly, understand what a repeating decimal is. A repeating decimal is a decimal number that has a repeating pattern of digits after the decimal point, such as 0.333... or 0.272727...
Now, let's consider two repeating decimals as examples: 0.333... and 0.666...
Add these two repeating decimals together:
  0.333...
+ 0.666...
---------
= 0.999...
Observe that the result, 0.999..., is also a repeating decimal. In fact, it is mathematically equal to the integer 1. This demonstrates that the sum of two repeating decimals can be an integer.
Let's consider another example: 0.333... and 0.467467...
Add these two repeating decimals together:
  0.333...
+ 0.467467...
------------
= 0.800467...
In this case, the sum of the two repeating decimals is a mixed decimal with a terminating part (0.800) and a repeating part (467).

The given system of equations, x + (1/2)y = 1 and 20x + 10y = 6, has no solution. The equations represent parallel lines that do not intersect, indicating that there are no common points of intersection.

To determine the number of solutions in the given system of equations, we can analyze the coefficients of the variables. The first equation can be simplified as 2x + y = 2, while the second equation can be simplified as 20x + 10y = 6. By comparing the coefficients, we can see that the second equation is obtained by multiplying the first equation by 10. This indicates that the two equations represent the same line and are dependent.

When two equations represent the same line, they intersect at infinitely many points, which means there are an infinite number of solutions. However, in this case, the two equations have different right-hand side constants (1 and 6), indicating that the lines are parallel and will never intersect. Therefore, there are no common points of intersection and no solution exists.

Step-by-step explanation:

Based on the given equation y = X + 3, the solution is X = y - 3.

First, we use the property of equality, which allows us to perform the same operation on both sides of the equation to solve for X.

Here we subtract 3 from both sides of the equation as follows:

Y-3 = X + 3-3

Then we simplify the right-hand side:

Y-3 = X

So X = Y - 3

Therefore the equation y = X + 3 is X = Y - 3.

Answer:

4.95 mL

Step-by-step explanation:

Since we have 400 mg/m² of gemcitabine for a patient whose BSA is 0.47 m², the mass of drug required for the patient is thus m = 400 mg/m² × 0.47 m² = 188 mg.

Also, since 200 mg vial of gemcitabine for injection that contains 38 mg per mL, so the concentration of gemcitabine is 38 mg/mL.

Since concentration = mass/volume, and

volume = mass/concentration,

the volume of gemcitabine injection required is

V = mass of gemcitabine/concentration of gemcitabine in injection

V = 188 mg/38 mg/mL

V = 4.95 mL

Using the binomial distribution, it is found that there is a 0.027 = 2.7% probability that he makes exactly 1 of the 3 free throws.

For each free throw, there are only two possible outcomes, either he makes it, or he misses it. The results of free throws are independent from each other, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

The parameters are:

In this problem:

The probability that he makes exactly 1 is P(X = 1), hence:

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 1) = C_{3,1}.(0.9)^{1}.(0.1)^{2} = 0.027\)

In linear equation, the intersection at coordinate (9, 315).

What in mathematics is a linear equation?

Gym one:

f(x) =80 x + 25

Gym two:

g(x) = 35x (+ 0 [since there was no joining fee])

The first month is easy.

Gym one's cost is just the joining fee plus the one month of membership fee. Or...

Gym two's cost is just that first month's membership fee. Or...

35 = 35(1) + 0

then  second month

The lowest temperature is usually around 3 degrees Celsius (3°C), and the highest temperature is around 18 degrees Celsius (18°C).

The temperature is typically halfway between the daily high and daily low at both 10 a.m. and 10 p.m. Additionally, the highest temperatures are usually in the afternoon.

During the morning, the sun starts to warm up the atmosphere, causing the temperature to rise from its lowest point. By 10 a.m., the temperature has increased but is not yet at its peak.

Similarly, during the evening, the sun starts to set, resulting in a gradual decrease in temperature from its highest point. By 10 p.m., the temperature has dropped but is not yet at its lowest point

The temperature at 10 a.m. and 10 p.m. is typically halfway between the daily high and daily low because it represents the transition period between the warmest and coolest parts of the day.

Question:

Davis wants to pour 5 gallons of punch into ½ gallon jugs How many jugs will he need?

A. 2½

B. 5½

C. 10

D. 15

Answer:

Number of jugs = 10

Davis will need 10 jugs to pour 5 gallons of punch into ½ gallon jugs.

Step-by-step explanation:

David has 5 gallons of punch that he wants to pour into jugs.

The capacity of 1 jug is ½ gallon.

The required number of jugs may be found as

Number of jugs = gallons of punch/capacity of jug

For the given case, we have

Gallons of punch = 5

capacity of jug (in gallons) = ½ = 0.5

So, the required number of jugs is,

Number of jugs = 5/½

Number of jugs = 5/0.5

Number of jugs = 10

Therefore, Davis will need 10 jugs to pour 5 gallons of punch into ½ gallon jugs.

Correct proportion for AABC: <A <B <C

Incorrect proportion for ARST: <R <T <S

To determine a correct proportion for AABC and an incorrect proportion for ARST, we need to analyze the given information.

1. AABC:

From the given information, we know that <C is a right angle (90°) and <B is 61°. Since the sum of angles in a triangle is always 180°, we can find <A by subtracting the known angles from 180°.

<A = 180° - <C - <B

<A = 180° - 90° - 61°

<A = 29°

Therefore, the correct proportion for AABC is:

<A <B <C

29° <B 61° <C

2. ARST:

The given information states that <R is 29° and <T is a right angle (90°). To find <S, we subtract the known angles from 180° (since it's a triangle).

<S = 180° - <R - <T

<S = 180° - 29° - 90°

<S = 61°

Therefore, the incorrect proportion for ARST is:

<R <T <S

29° <T 61° <S

In conclusion, the correct proportion for AABC is <A <B <C (29° <B 61° <C), while the incorrect proportion for ARST is <R <T <S (29° <T 61° <S).

Answer:

c. $1,753.05; yes

Step-by-step explanation:

All calculations below are done on a monthly basis.

Gross salary in 1 month: $1675

Deduct 6.2% from gross salary:

0.062 * $1675 = $103.85

$1675 - $103.85 = $1571.15

Deduct 1.45% from gross salary:

0.0145 * 1675 = $24.29

$1571.15 - $24.29 = $1546.86

Deduct $975.23:

$1546.86 - $975.23 = $571.63

The expenses of $35 and $75.51 are biweekly. Since we are calculating per month, we multiply each of the expenses by 2.

Deduct 2($35) and 2($75.51):

$571.63 - $70 - $151.02 = $350.61

The amount saved per month is $350.61.

In 5 months, the amount saved is 5 * $350.61 = $1753.05

$1753.05 is greater than $1,600.
