Daria pays x dollars for a pair of shoes. The tax on shoes is
6%. The expression representing her total cost is x + 0.06x.
Which expression is equivalent and why?
A. (0.06) because the cost of the shoes can be factored out.
OB. 1.6x because adding 6% to the cost of the shoes is the same as
multiplying the cost by 1.6.
O.
C. 1.06x because adding 6% to the cost of the shoes is the same as
multiplying the cost by 1.06.
D. 1.06x because adding $6 to the cost of the shoes is the same as

What is the next term of the following sequence? 20, 10, 5, 2, 1/2 ...

A:3/4
B:1 1/2
C:1 1/4

Answers

Answer:

I'm thinking it's A...

Answer:  C) 1 & 1/4

==================================================

Explanation:

I'm assuming you meant to say 2 & 1/2 instead of 2,1/2

If so, then we cut that last term 2 & 1/2 in half

The whole part 2 cuts in half to 1

The fractional part 1/2 cuts in half to 1/4

2 & 1/2 cuts in half to 1 & 1/4 which leads to choice C

The reason why we cut in half is because the jump from 20 to 10 is "divide by 2", and the same applies from 10 to 5, and from 5 to 2 & 1/2.

Answer:

Equation of line l,

3x-4y=1/2

y=3/4x-1/2

we get,

slope of line l =3/4

Equation of line m,

x-5=2y

y=1/2-5/2

Hence slope of line m=1/2

Slope of line l is not equal to slope of line m. Hence the line are not parallel.

Slope of line l* slope of line m ,

(3/4)*(1/2) =3/8

Since the product of slope of line l and the slope of line m is not equal to -1, the lines are not perpendicular.

Hence the lines are neither perpendicular nor parallel..

Answer:

none are parallel

Which expression uses the greatest common factor and the distributive property to rewrite the sum 7 + 75

Answers

Answer:

[tex]75 + 45[/tex] [tex]= 15(3 + 5)[/tex]

Step-by-step explanation:

Given

[tex]75 + 45[/tex] -- Corrected

Required

Use the GCF to write it as a distributive property

First, we find the GCF of 75 and 45

[tex]45 = 3 * 3 * 5[/tex]

[tex]75 = 3 * 5 * 5[/tex]

The common factor is:

[tex]GCF = 3 * 5[/tex]

[tex]GCF = 15[/tex]

So, [tex]75 + 45[/tex] becomes

[tex]75 + 45[/tex] [tex]= 15 * 3 + 15 * 5[/tex]

Factorize

[tex]75 + 45[/tex] [tex]= 15(3 + 5)[/tex]

Hence, the sum has been rewritten as [tex]15(3 + 5)[/tex]

How wide should the border be, if she wants to use all the crushed
rock?

Answers

9514 1404 393

Answer:

  25.5 cm

Step-by-step explanation:

If the walk is x meters wide, it adds 2x to the overall length and width. Then the area of the walkway is ...

  (2x +5)(2x +6.25) -(5)(6.25) = 6

  4x^2 +22.5x = 6 . . . . simplify left side

  4x^2 +22.5x -6 = 0 . . . subtract 6 to put into standard form

Using the quadratic formula, the walkway width can be found to be ...

  x = (-22.5 +√(22.5² -4(4)(-6)))/(2(4)) = (-22.5 +√602.25)/8

  x ≈ 0.25510

The border width should be about 25.5 cm.

Answer:

[tex] - \frac{5}{6} [/tex]

Step-by-step explanation:

The first thing to do is solve for the root. A trick is to ignore the numerator and only focus on the denominator in the root. So it is a third root so you have to find out what multiplied by itself three times is 343. The correct answer for that is 7. So now we must introduce the numerator back, so it would be:

[tex] \frac{1}{7} [/tex]

I'll show the new expression below.

[tex] \frac{1}{6} - 7( \frac{1}{7} )[/tex]

Second order of business is to multiply the second half of the expression. Easy enough the 7 cancels out the 1/7. New expression below.

[tex] \frac{1}{6} - 1[/tex]

Now just solve for that.

[tex] - \frac{5}{6} [/tex]

Answers

Let 'n' be the original number

Let 'a' be the digit in the ten's place of 'n'

Let 'b' be the digit in the one's place of 'n'

Then, n = 10a + b

We have,

a+b = 11 -------- (equation 1)

Let m be the number formed when the digits of n are reversed

Then, m = 10b + a

Given that, m = n + 27

=> 10b + a = (10a + b) + 27

=> 9b - 9a = 27

=> 9(b - a) = 27

=> b - a = 3 ----- (equation 2)

Adding equation 1 and 2, we get

2b = 14

=> b = 7

putting b = 7 in equation 1

a + 7 = 11

=> a = 4

Therefore original number is 10×4 + 7 i.e. 47

Determine if the equations are parallel, perpendicular or neither x-y=5 and x+y=-10

Answers

Answer- perpendicular

Work shown: x-y=5 —-> subtract x from both sides to give you y alone. -y= -x+5 —-> next step is to continue to get y alone so you have to divide both sides by -1. y=x-5 now the first one is done
x+y=-10 —-> solve to get y alone so subtract both sides by x making it y=-x-10 Meaning that the two lines are perpendicular to each other.

Answer: Perpendicular

Step-by-step explanation: x-y=5 —-> subtract x from both sides to give you y alone. -y= -x+5 —-> next step is to continue to get y alone so you have to divide both sides by -1. y=x-5 now the first one is done

x+y=-10 —-> solve to get y alone so subtract both sides by x making it y=-x-10 Meaning that the two lines are perpendicular to each other.
