Answer:

The correct answer is $5,29

Step-by-step explanation:

The unit price helps us determine the price for a single unit of something that has been purchased in a group.

In this case we have a package of 5 pairs of insulated gloves, which includes 5 pairs and costs 29.45.

We want to know what the unit price is, that is, how much does a single pair of gloves cost.

To determine this we simply divide the total price by the number of gloves:

29.45 / 5 = 5.29

In this way we can confirm that the unit price of a pair of insulated gloves is $ 5.29.

Answer:

Each pair of gloves is $5.29

Answer:

7

Step-by-step explanation:

We know the decimal place is after all those zeroes. Move the decimal x places to the left, until it is located between the 2 and 8. Since it moved 7 spaces, that is how you know the power of the ten. A faster way of doing this is the power is always one less than the number of digits of the number.

Answer: 7

Step-by-step explanation:

Answer:

$1.36

Step-by-step explanation:

First, add together the prices of all the clothes:

18.28 + 42.39 + 12.97

= 73.64

Then, subtract this from 75:

75 - 73.64

= 1.36

So, he will have $1.36 left after buying the clothes

The money Marco have left after he buys his clothes is $1.36.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, Marco has $75 to spend on new clothes for a job interview.

Let the money left after he purchase his clothes be x.

Cost of shirt=$18.28, cost of pants=$42.39 and cost of tie =$12.97

Now, x=75-(18.28+42.39+12.97)

x= 75-73.64

x= $1.36

Therefore, the money Marco have left after he buys his clothes is $1.36.

Answer:

Step-by-step explanation:

Answer:

26

Step-by-step explanation:

Subtract the mean (84) from each of the four scores, obtaining

2, -3, 3, - 2

These are the "deviations."

Next, square each of these four deviations, obtaining

(2)^2 = 4, and:

(-3)^2 = 9, and:

(3)^2 = 9, and:

(-2)^2 = 4

Then the sum of the squared deviations of the scores from the mean is 26.

Answer:

v=6

Step-by-step explanation:

-42=4v-18

Add 18 to each side

-42+18=4v-18+18

-24 = 4v

divide each side by 4

-24/4 = 4v/4

-6 = v

Answer:

v = -6

Step-by-step explanation:

Isolate the variable, v. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 18 to both sides:

-42 (+18) = 4v - 18 (+18)

-42 + 18 = 4v

4v = 18 - 42

4v = -24

Next, divide 4 from both sides:

(4v)/4 = (-24)/4

v = -24/4

v = -6

v = -6 is your answer.

Answer:

b/(2-3)

Step-by-step explanation:

The expression for the quotient of b divided by the difference of two minus three is q = b / (2 - 3) and can be simplified as q = -b.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement.

A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.

Given:

The quotient of b divided by the difference of two minus three,

The expression for the above statement can be written as,

Assume the quotient is q then,

q = b / (2 - 3)

The denominator can be simplified as,

q = b / (-1)

q = -b

Answer:

(-9, 10)

Step-by-step explanation:

The location of the midpoint of a line with endpoint at ([tex]x_1,y_1[/tex]) and ([tex]x_2,y_2[/tex]) is given as (x, y). The location of x and y are:

[tex]x = \frac{x_1+x_2}{2},y=\frac{y_1+y_2}{2}[/tex]

Given the endpoint (9,8) and Midpoint (0,9), the location of the other endpoint can be gotten from:

[tex]0=\frac{9+x_2}{2}\\ \\9+x_2=0\\\\x_2=-9\\\\Also,9=\frac{8+y_2}{2}\\ \\8+y_2=18\\\\y_2=18-8\\\\y_2=10[/tex]

Hence the endpoint is at (x2, y2) which is at (-9, 10)

Answer:

radius is 4.5 km

Step-by-step explanation:

Given :

Total number of people living in the area = 1.15 million = 1150000

Population density = 18075 people per sq kilometer

To find:

Radius of region = ?

Solution:

Population density of a region is defined as the ratio of total population divided by the area of the region.

Area here is circular. Let the radius be = r

Area of circle is given as [tex]\pi r^2[/tex]

Formula:

[tex]Population\ Density = \dfrac{Total\ population}{\pi r^2}[/tex]

Putting the values:

[tex]18075 = \dfrac{1150000}{\pi r^2}\\\Rightarrow r^2 = \dfrac{1150000}{18075\pi }\\\Rightarrow r^2 = \dfrac{63.62}{\pi }\\\Rightarrow r^2 = 20.26\\\Rightarrow \bold{r=4.5\ km}[/tex]

Therefore, radius is 4.5 km.

Step-by-step explanation:

Its linear because y=x/2 + 6 is equal to y = 1/2x+6 which is a linear function

w = 57.5 yards

l = 169.5 yards

P = 2w + 2l

466 = 2w + 2l

l = 3w - 3

466 = 2w + 2(3w - 3)

466 = 2w + 6w - 6

466 - 6 = 8w

8w = 460

w = 460 : 8

w = 57.5 yards

l = 3w - 3

= 3×57.5 - 3

= 169.5

l = 169.5 yards

Answer: Jeffery paid $ 2937 in all.

Step-by-step explanation:

Given: The cost of antique pull = $890

Mark up percentage = 200%

New price = (cost) + (Mark up percentage) x (cost)

[tex]=\$( 890+\dfrac{200}{100}\times890)\\\\=\$( 890+2(890))\\\\=\$2670[/tex]

After a tax of 10% , the amount needs to be paid = New price + 10% of New price

 [tex]=\$(2670+\dfrac{10}{100}\times2670)=\$(2670+267)\\\\=\$2937[/tex]

Hence, Jeffery paid $ 2937 in all.

Answer:

179 minutes

Step-by-step explanation:

From the information given, you know that the total cost of the long distance service is equal to 7 plus the result of multiplying 0.7 for the number of minutes:

Total cost=7+0.07x, where x is the amount of minutes.

Now, you can replace the total cost with 19.53 that is the amount Ali was billed and solve for x:

19.53=7+0.07x

19.53-7=0.07x

12.53=0.07x

x=12.53/0.07

x=179

According to this, the answer is that Ali was billed for 179 minutes.

Answer:

B

Step-by-step explanation:

p(x) = x² - 2√2x + 1

p(2√2) = (2√2)² - 2√2*2√2 + 1

           =2²*(√2)² - 2*2*√2*√2  + 1

           = 4 *2 - 4*2 + 1

           = 8 - 8 + 1

           = 1

Answer:

B

Step-by-step explanation:

Given

p(x) = x² - 2[tex]\sqrt{2}[/tex] x + 1, then

p(2[tex]\sqrt{2}[/tex] )= (2[tex]\sqrt{2}[/tex] )² - 2[tex]\sqrt{2}[/tex](2[tex]\sqrt{2}[/tex] ) + 1 = 8 - 8 + 1 = 1 → B
