what is the geometric mean of 4/5 and 2​

Answer:

A store pays $840 for an oil painting. The store marks up the price by 46%. What is the amount of the mark-up?

=

$386.40

Answer:

She will pay a tax of $9.45

Step-by-step explanation:

The question doesn't seem complete, but since we are given her tax rate, then they would surely ask for the amount of tax she paid. So let's work on this.

We are told that she bought two pairs of shorts and one short goes for $25 each, this implies that she will get the two for:

= $25 × 2

= $50

We are also told that she got four shirts that have an average cost of $19 per shirt. This implies that she will get the four shirt for:

= $19 × 4

= $76

Since she will have to pay a tax of 7.5%, then we will calculate it as:

= 7.5% × ($50 + $76)

= 0.075 × $126

= $9.45

Answer:

A. $9.45

B. Total cost = $135.45

Step-by-step explanation:

PART A: If she buys all of the items, how much sales tax will she have to pay?

The sales tax for Brandi's purchase will be $(insert answer here)

PART B: What is the total cost of her purchase including sales tax?

Brandi will spend $(insert answer here) on her purchases, including sales tax.

A.

Total amount earned = $140

Two pairs of shorts = $25 each

Total cost of 2 shorts = 2 shorts × $25 each

= $50

Four shirts = $19 each

Total cost of 4 shirts = 4 × $19

= $76

Amount of Sales tax = 7.5% of Total cost of 2 shorts + Total cost of 4 shirts

= 7.5% ($50 + $76)

= 0.075 × 126

= $9.45

Total cost = Total cost of 2 shorts + Total cost of 4 shirts + Amount of Sales tax

= $50 + $76 + $9.45

= $135.45

Therefore, she has enough money to buy all the items she likes

Answer: 18² + 15² = 27²

Step-by-step explanation:

The side lengths of the triangle are 15cm, 18cm and 27cm. To know if it's a right angle triangle, the square of the length of the longest side which is the hypothenuse must be equal to the square of the two other sides. This will be:

18² + 15² = 27²

324 + 225 = 729

549 = 729

Since the answers gotten isn't equal, it is not a right angle triangle.

Answer:

x−3=x−3

Step-by-step explanation:

Evaluate (2x−1)−7, then set it equal to 2.

Subtract 7 from −1 = 2x−8

Solve 2x−8=2.

Move all terms not containing x to the right side of the equation.

Add 8 to both sides of the equation=2x=2+8

Add 2 and 8=2x=10

Divide each term by 2 and simplify.

Divide each term in 2x=10 by 2=2x/2=10/2

Cancel the common factor of 2

Cancel the common factor=10/2

Divide x by 1=x=10/2

Divide 10 by 2=x=5

Remove parentheses=x−3

List all of the solutions.

5=

(2x−1)−7=2=x=5

x−3=x−3

The answer is 1.97 meters per second

Step-by-step explanation:

Plz give brainliest thanks :) Let me explain you how you do this Housefly is 1.967

The 7 is the tenth and the 6 is the hunderth

1.967 round to 1.96 from the hunderths because the last number is greater than 5 so you round up!

Answer:

1.97

Step-by-step explanation:

REMEMBER: 5 or higher, round up, 4 or lower, round down

Since 7 is above 5, we round it up, turning 1.967 to 1.97

Answer:

A. I only

Step-by-step explanation:

Given the functions

h(x)= -2x - 1 g(x)= -1/2x + 1/2

h(g(x) =h( -1/2x + 1/2)

=f((-x+1)/2)

We are to replace x in h(x) with -x+1/2

h((-x+1)/2) = -2(-x+1)/2 + 1

h((-x+1)/2) = -(-x+1)+1

h((-x+1)/2)= x-1+1

h((-x+1)/2) = x

h(g(x) = x

Also for g(h(x))

g(h(x)) = g(-2x-1)

Since g(x) = -x+1/2

g(-2x-1) = -(-2x-1)+1/2

g(-2x-1) =2x+1+1/2

g(-2x-1) = 2x+2/2

g(-2x-1) = 2(x+1)/2

g(-2x-1) = x+1

Sine g(h(x)) ≠ h(g(x)), hence both functions are not inverses of each other

Hence I. The function h(g(x)) = x is the only correct option. Option A is correct

The correct option is: A. I only

We have functions:

[tex]h(x)= -2x - 1 \\g(x)= -\frac{1}{2} x +\frac{1}{2} \\h(g(x)) =h(-\frac{1}{2} x +\frac{1}{2}) \\h(g(x))=f(\frac{-x+1}{2} )[/tex]

Now, replace x in h(x) by [tex]\frac{-x+1}{2}[/tex]

So,

[tex]h(\frac{-x+1}{2} ) = -2(\frac{-x+1}{2}) + 1\\h(\frac{-x+1}{2} ) = -(\frac{-x+1}{2}) + 1\\h(\frac{-x+1}{2} )= x-1+1\\h(\frac{-x+1}{2} )=x\\h(g(x)) = x[/tex]

Now, g(h(x))

g(h(x)) = g(-2x-1)

Since [tex]g(x) = \frac{-x+1}{2}[/tex]

[tex]g(-2x-1) = \frac{-(-2x-1)+1}{2} \\g(-2x-1) =\frac{2x+1+1}{2}\\g(-2x-1) =\frac{2x+2}{2}\\g(-2x-1) = x+1[/tex]

As g(h(x)) ≠ h(g(x)),

Therefore, both functions are not inverses of each other.

Hence A. I only

The function h(g(x)) = x is the only correct option.

So, option A is correct.

Given:

Converting rational exponents to radical notation.

To find:

The correct statements.

Solution:

According to the property of exponents, conversion of rational exponents to radical notation is

[tex]x^{\frac{a}{b}}=\sqrt[b]{x^a}[/tex]

In [tex]x^\frac{a}{b},[/tex] x is base, a is numerator of the rational exponent and b is denominator of the rational exponent.

In [tex]\sqrt[b]{x^a}[/tex], x is radicand, a is power of radicand and b is index of radical notation.

Denominator of the rational exponent becomes the index of the radical notation.

Numerator of the rational exponent becomes power of the radicand in the radical notation.

Therefore, the correct options are 4 and 5.

Using the conversion of rational exponents to radical notation, it is found that the correct options are:

4. Denominator of the rational exponent becomes the index of the radical notation

5. Numerator of the rational exponent becomes power of the radicand in the radical notation

The conversion of rational exponents to radical notation is modeled by:

[tex]a^{\frac{n}{m}} = \sqrt[m]{a^n}[/tex]

That is:

A negative exponent just is represented by a fraction, as [tex]a^{-\frac{n}{m}} = \frac{1}{a^{\frac{n}{m}}}[/tex], hence the radical is not negative, and item 2 is incorrect.

Step-by-step explanation:

The absolute value of a number is the distance from the zero. This can be positive or negative forming the absolute number. The distance is negative when the number is positive. The absolute numbers are used in the equations for the solutions. The numbers greater than zero are positive numbers.

Answer: 5/6?

Step-by-step explanation:

Answer:

39

Step-by-step explanation:

15/25 = 0.6 - She can read 0.6 pages in 1 minute.

0.6 X 65 = 39

There are 39 pages she can read in 65 minutes.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

Jamie reads 15 pages in 25 minutes

And, wants to know how many pages she can read in 65 minutes

Now, Let number of pages read in 65 minutes = x

Hence, We can formulate;

x / 65 = 15 / 25

x = 15 x 65 / 25

x = 39

Thus, There are 39 pages she can read in 65 minutes.
