Find the sum: 1/3+1/4

Answer:

50.28 m²

Step-by-step explanation:

Area of a circle = pi r²

= 22/7 × 4 × 4

= 50.28 m²

If the expression is log a², then the expansion of this expression looks like 2 log a.

Given that the expression is log a².

We are required to find the expansion of the expression.

The change of base formula gives the way to re-write a logarithm operation as a fraction of logarithms with a new base.

We know that log [tex]a^{b}[/tex]=b log a.

The expression is log a². So,

log a²=2 log a   (Power of a will come in front of log)

Hence if the expression is log a², then the expansion of this expression looks like 2 log a.

If you have applied for two jobs a and b and the probability that you get an offer for the job a is 0.25 and the probability of being offered job b is 0.20, then the probability that you will be offered both jobs is 0.05.

Probability is a term used in mathematics that is concerned with the numerical illustration of the possibility of an event to take place. Its value is between 0 and 1 where 0 illustrates the impossibility of the event to take place while 1 illustrates the certainty of an event to take place.

As the probability of both the jobs are not dependent on each other, the probability that both jobs will be offered can be calculated by the formula;

P(A∩B) = P(A) × P(B)

Here, P(A∩B) represents the probability of both the events to take place together

As P(A) is equal to 0.25

P(B) is equal to 0.20

P(A∩B) = (0.25)(0.20)

P(A∩B) = 0.05

Therefore, 0.05 is the probability that both jobs will be offered.

According to the solving Mrs. Weatherford spends 15 percent of each weekday  25 hours and 20 minutes in her car.

A % is a relative figure that represents the hundredth part of any amount. One percent (symbolized 1%) is one hundredth part; consequently, 100 percent denotes the complete amount and 200 percent defines twice the supplied amount.

The most fundamental use of percentages is really to compare one number to another, with the second number rebased to 100. Assume we want to know the number among employed females as both a percentage of all employees.

Mrs. Weatherford drives 15% of the time during the week.

We know that:

1 week  = 7days

1day  = 24 hours

So 7 days  = 7 x 24

                  = 168 hours

Mrs. Weatherford drives 15% of the time during the week.

So,

(168/100) * 15

1.68 * 15

25.2 hours

According to the solving Mrs. Weatherford spends 25 hours and 20 minutes in her car.

The fractions 16/20, 12/15, and 8/10 are equivalent fractions to 4/5.

When writing equivalent fractions, the numerator and denominator should be multiplied or divided by the same number. This is the reason why when these fractions are simplified, they are reduced to the same value.

Let us understand the two ways in which we can make equivalent fractions:

Now, Divide the denominator or numerator by the same number or multiply the denominator and the numerator by the same number.

So, the equivalent fractions for 4/5 are:

(4/5) × (2/2) = (4 × 2) / (5 × 2) = 8/10

(4/5) × (3/3) = (4 × 3) / (5 × 3) = 12/15

(4/5) × (4/4) = (4 × 4) / (5 × 4) = 16/20

After simplifying, 16/20, 12/15, and 8/10 equal 4/5, indicating that they are identical in nature.

Answer:

Thank you, if you need more clarification on the system of parallelograms, let me know.

Answer:

n = (f + w)/b

Step-by-step explanation:

bn - w = f

Rearrange the equation so that the subject is on its own, in the format Ax = B

bn - w + w = f + w

bn = f + w

Isolate the subject, so that it's in the format x = C

bn = f + w

bn/b = (f + w)/b

n = (f + w)/b

The total length between the two fences is 136 ft, and the total cost is 164.56 dollars.

We have a square garden with a perimeter of 60ft. Then if the sidelength of the square is S, we have that:

60ft = 4*S

S = 60ft/4 = 15ft

We know that the first fence is around the perimeter of the garden, so the length of the first fence is exactly 60ft.

Now, the other fence is 2ft away from the first fence, so it forms a square of sidelength of:

15ft + 2*2ft = 19ft

Then the perimeter of this square is:

P = 4*19ft = 76ft

This means that the length of the second fence is 76 ft.

So the total length of fence is 76ft + 60ft = 136ft

And the cost is $1.21 per ft, then the total cost for the fence is:

The result of simplifying each number 1000⁴/₃ / 100³/₂ using the exponent rules is: 10

To solve this exercise we have to resolve algebraic operations following the exponent rules.

(1000⁴/₃) / (100³/₂)

Base: 1000 = 10³

Base: 100 = 10²

As 1000 is the same as 10³ and 100 is the same as 10², we get:

(10³)⁴/₃ / (10²)³/₂

Using the power of a power rule that indicates that: the exponent result will be the multiplication of these exponents, we have:

10³*⁴/₃ / 10²*³/₂

10¹²/₃ / 10⁶/₂

10⁴ / 10³

Using the quotient rule that indicates that: the exponent result will be the subtraction of these exponents, we have:

There will be a 6% rise using the 0.9646 multiplier, then a 9% reduction.

Simply said, a multiplier is a factor that increases the basic value of another object. For example, a 2x multiplier would double the initial value. On the other hand, a multiplier of 0.5x would actually cut the basic amount in half. In finance and economics, multipliers come in a wide variety.

Say that Number is 100N.

growth of 6%

= (6/100)100N

= 6N

Number following reduction: 100N + 6N = 106N

9% lessening

= (9/100)106N

When 4 nightstands are sold the profit is $1800 since the number of nightstands sold is directly proportional to the profit.

The profit is defined as difference between the cost price and sell price for a product.

A directly proportional relationship means that if two variables x and y are proportional to one another then there exist a constant k such that x = y × k .

The graph of a directly proportional equations is a straight line passing through the origin.

Given that the profit is $900 for 2 sold nightstands, $3600 for 8 night stands and $4500 for 10 sold nightstands.

Now this relationship is directly proportional.

The numeric values for the function are given as follows:

A. f(a) = 9a - 9.

B. f(a + h) = 9a + 9h - 9.

C. f(a + h) - f(a) = 9h.

D. (f(a + h) - f(a))/h = 9.

To find the numeric value of a function, we replace each instance of the variable by the desired value.

For this problem, the function is given by:

f(x) = 9x - 9.

At x = a, the numeric value is given by:

f(a) = 9(a) - 9 = 9a - 9.

Hence:

f(a) = 9a - 9.

At x = a + h, the numeric value is given by:

f(a + h) = 9(a + h) - 9 = 9a + 9h - 9.

Hence:

f(a + h) = 9a + 9h - 9.

Subtracting these values, we have that:

f(a + h) - f(a) = 9a + 9h - 9 - 9a + 9 = 9h.

Hence:

f(a + h) - f(a) = 9h.

Dividing by h, we have that:

(f(a + h) - f(a))/h = 9h/h = 9.

Hence:

(f(a + h) - f(a))/h = 9.

The isolated value of h is found to be V/πr²

The three-dimensional solid shape of a cylinder is made up of two parallel bases connected by a curved surface. These bases have the shape of a spherical disc. The axis of the cylinder is a line drawn through the centre or connecting the centres of two circular bases. The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it. The formula πr²h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder. Any substance that can fill the cylinder consistently with liquid or another material may be used as the component.

According to given formulae:

V=πr²h

On dividing both side with πr² we get

Part A: Expression to represent the total amount of juice left in the jar : (0.25 +0.30 + 0.75) - 0.20

Part B: Simplifying above expression using properties of addition and subtraction gives that total amount of juice left is  1.1 liter.

An expression is a group of terms consisting of numbers and mathematical operators ( +, -,*,/) and "=" is not there.

Given that a  jar contains 0.25 liter of apple juice, 0.30 liter of grape juice, 0.75 liter of pineapple. Melissa then drank 0.20 liter of the mixture.

Therefore, total juice in the jar before Melissa drank it = quantity of (apple juice + grape juice + pineapple juice ) = (0.25+ 0.30+0.75) liters

After Melissa drank 0.20 liter juice left = total  juice before - 0.20

Thus, Expression to represent the total amount of juice left in the jar is: (0.25 +0.30 + 0.75) - 0.20

And it can be solved as (0.25 +0.30 + 0.75) - 0.20 = (0.55+0.75)-0.20

                                                                                   = 1.30-0.20 = 1.1 liter

Thus, after simplifying expression we get that the left juice in the jar is 1.1 liter.
