Darla can spend the greatest total cost of groceries in order to spend as close to $15 as possible is approximately $14.20.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Let the cost of the groceries be represented as "c", then we have;

Cost price + VAT = c + (5% of c)

In order to get the cost, c, that make him spend as close to $15. Since the tax is 5% of the cost price, then the cost price will be close to $15.

Let c = $14.20, then;

So that,

c + (5% of c) = 14.20 + (5% of 14.20)

                   = 14.20 + 0.71

                   = $14.91

Therefore, the greatest total cost of groceries she can spend in order to spend as close to $15 as possible is approximately $14.20.

Answer:

(1, 1) , (5, 2), (6, 4), (4, 7) and (2, 3)

Step-by-step explanation:

When a point is rotated 180° about the origin(either clockwise or anticlockwise), the transformed coordinates are the negatives of the original coordinates.

Thus when a point (x, y) is rotated about the origin, its new coordinates become (-x, -y)

Given the original 5 vertices of the pentagon, the vertices of the rotated pentagon are transformed as follows

Original Vertex    ==>     Transformed Vertex

(-1, -1)                      ==>          (1, 1)
(-5, -2)                    ==>          (5, 2)
(-6, -4)                    ==>          (6, 4)
(-4, -7)                    ==>          (4, 7)
(-2, -3)                    ==>          (2, 3)

The sum of (-3) + (-1) is -4.

The addition expression (-3) + (-1) on a number line is : (-4).

Here, we have,

To represent the addition expression (-3) + (-1) on a number line,

we would start at -3 and move to the left by 1 unit.

Here's how we can explain it step by step:

Start at -3 on the number line.

Since we have a negative sign in front of both numbers, we will move to the left (in the negative direction) on the number line.

The first number, -3, indicates that we will start at -3 on the number line.

The second number, -1, indicates that we will move to the left by 1 unit from -3.

When we move to the left from -3 by 1 unit, we will reach -4 on the number line.

So, (-3) + (-1) represented on the number line means starting at -3 and moving to the left by 1 unit, resulting in -4.

The sum of (-3) + (-1) is -4.

The area of a rectangular cement walkway of width x meters around a 50m by 25m pool is 4x²+150x sq. meters.

Rectangle area in geometry refers to the area that a rectangle occupies on a two-dimensional plane. A rectangle is a form of a quadrilateral, a two-dimensional object with four sides and four vertices. The four angles of the rectangle are all perfectly right angles or 90 degrees. The opposing sides of the rectangle are equal and parallel.

Area of Rectangle = Length × Breadth

In the given question,

The width of the walkway is x meters.

Width of the pool= 25+2x meters

and the Length= 50+2x.

So the area of the walkway with the pool is

= (25+2x)+(50+2x)

= 1250+100x+50x+4x²

= 4x²+150x+1250 sq. m

Area of the pool= 50x25

= 1250 sq. m

Area of the walkway= 4x²+150x+1250-1250

= 4x²+150x sq. meters.

Hence, the answer is 4x²+150x sq. meters.

The simplification of the given logarithmic functions ln (2x-1)² = 7 is 17.055.

The logarithm of a number is the exponent by which a fixed value referred as the base should always be raised to generate a certain number. For instance, because 1000 is 10 to the third power, a log of 1000 to base 10 is 3.

Some properties of the logarithmic functions are defined as-

As, for the stated log or ln function ln (2 x-1)²=7

Use the power rule on the left side of the equation.

2 ln (2 x-1) = 7

Simplifying the equation.

ln (2 x-1) = 7/2

ln (2 x-1) = 3.5

Using the exponential property of the log.

e∧[ln (2 x-1)] = e∧3.5

2x-1 = 33.11

2x = 33.11 + 1

2x = 34.11

x = 34.11/2

A = P (1 + r/n) (nt)

where

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per year

t = the number of years the money is invested or borrowed for

here

we have to found semianually

We need to know about logarithm to solve this problem. The exponential form of the logarithm is [tex]2^{7} =128[/tex].

Logarithm is the exponent that is raised to a base to get a certain number.There are a few rules of logarithm, log a+ log b can be written as log ab, log a -log b can be written as log a/log b, when the number whose logarithm is being calculated is raised to a power, then the power can be multiplied to the log itself. Logarithm when written as log without base mentioned, the base is 10, the log of a number that is same as the base is always 1, the log of 1 is always 0 because a nonzero number raised to 0 is always 1. To write a logarithm in exponential form we have to raise the value of the logarithm to the base which is equal to the number whose logarithm we found.

Answer:

Step-by-step explanation:

the complement of R is 90 - R , then

R = 5(90 - R) - 6

R = 450 - 5R - 6

R = 444 - 5R ( add 5R to both sides )

6R = 444 ( divide both sides by 6 )

R = 74°

complement = 90° - 74° = 16°

Option(a) 16 is correct option, the measure of the complement of R is 16

Two angles are complementary if their sum is 90°.

Let x be an angle and y be its complement of x then x + y = 90°.

Let the measure of the complement of R be x

Given that the measure of angle R is 6 less than 5 times its complement

Then 5 times the complement of R = 5x

And 6 less than 5 times the complement of R  = 5x-6

Thus, R = 5x -6

∴ R + complement of R = 90°

⇒5x-6 + x = 90

⇒6x = 96

⇒x = 96/6 = 16

Therefore, the measure of the complement of angle R is 16 and option (a) is correct option.

The answer to the present question is: log(a²b³/c⁴) = 2log(a) + 3log(b) - 4log(c)

For solving this kind of question, we are going to use these three identities:

log(x*y) = log(x) + log(y)   ....(1)

log(x/y) = log(x) - log(y)    ....(2)

log(xⁿ) = nlog(x)                ....(3)

So, using (2), log(a²b³/c⁴) may be written as: log(a²b³) - log(c⁴)  ....(4)

Again, using (1), log(a²b³) are often written as: log(a²) + log(b³)  ....(5)

Now, Putting equation (4) in equation (3), we get:

log(a²) + log(b³) - log(c⁴)   ....(5)

Now, using (3), expanding all the terms, we get:

log(a²) = 2log(a)log(b³) = 3log(b)log(c⁴) = 4log(c)

Putting of these in equation 5, we get:

2log(a) + 3log(b) - 4log(c)

Therefore,  log(a²b³/c⁴) = 2log(a) +3log(b) - 4log(c)

The equation can be expressed in Logarithmic form as log₃ 81 = 4

logarithmic form is a method to write equations when solving for a variable in an exponent.

Any exponential equation can be written as a logarithm. The logarithmic form is used to calculate an exponent of an equation.

The logarithmic form is a rearrangement of the exponential form. Exponential form: aᵇ = c

Logarithmic form: logₐ c = b

Comparing this with our equation, a=x, b=4, c=y

Therefore, we get the logarithmic form as log₃ 81 = 4

Hence, the Conversion from exponential form to logarithmic form gives the final answer as log₃ 81 = 4
