Answer:

$48.0

Step-by-step explanation:

Given data

Total cost of DVDs= $24.99+ $19.99

=$44.98

Let us compute the amount of the tax 6.75%

= 6.75/100* 44.98

=0.0675* 44.98

=$3.03615

The total cost including the tax is

=44.98+3.03615

=$48.0

Answer:

Percentage of missed puzzle pieces = 6%

Step-by-step explanation:

Total number of puzzle pieces = 250

Missed puzzle pieces = 15

Percentage of the missing puzzle pieces = [tex]\frac{\text{Missed puzzle pieces}}{\text{Total number of puzzle pieces}}\times 100[/tex]

= [tex]\frac{15}{250}\times 100[/tex]

= 15 × 0.4

= 6%

Therefore, percentage of missed puzzle pieces = 6%

Answer:

0.5 (or 0.50)

Step-by-step explanation:

So we have 6, 12, and 6.

Add them all together to get 24

12 of the skittles are green, so find the percentage/decimal.

12/24 = 0.5 (or 50%)

Answer:

neither I believe because they intersect

Answer:

-1/5

Step-by-step explanation:

Divide the numbers:

2/2n + 1 = 4/5

1n + 1 = 4/5

Multiply by 1:

1n + 1 = 4/5

n + 1 = 4/5

Subtract 1 from both sides of the equation:

n + 1 = 4/5

n + 1 -1 = 4/5 -1

Simplify:

N + 1 - 1 = 4/5 -1

N = 4/5 -1

N = 4/5 -1

And this is what you'll get:

N = -1/5

Hope this helps. :]

Answer:

AB  = 8

Step-by-step explanation:

Using the similarity theorem of a triangle;

AC/AD = AB/AE

AC = AB + BC and AD = AE + ED

AB + BC/AE + ED = AB/AE

Substitute the given values

AB+12/15 = AB/6

Cross multiply

6(AB+12) = 15AB

6AB + 72 = 15AB

15AB - 6AB = 72

9AB = 72

AB = 72/9

AB = 8

At value of x=4

A pair of numbers that describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines  are called coordinates. General form of coordinate is (x, y)

From the graph we can see , coordinates of that point where both the lines are intersecting is (4, -3)

Because x coordinate is = 4

and y coordinate is = -3

At the value of x=4, the two lines intersect each other

Answer:

Step-by-step explanation:

This is very easy, because the coefficients of the y terms are 2 and -2. You can easily eliminate the y terms by adding the equations together:

2x + 2y = 2

3x - 2y = 43

-----------------

5x + 0y = 45,  so x = 9

Use the value of x to solve for  y:

2(9) + 2y = 2

y = -8

x ≤ 3.5 gigabytes

Step-by-step explanation:

Under his cell phone plan, Anthony pays a flat cost of $56 per month and $4 per gigabyte. He wants to keep his bill under $70 per month.

Let us represent the number of gigabytes = x

Hence, our Equation is:

$56 + $4 × x ≤ $70

56 + 4x ≤ 70

Collect like terms

4x ≤ 70 - 56

4x ≤ 14

x ≤ 14/4

x ≤ 3.5 gigabytes

Therefore, the number of gigabytes Anthony can use while staying within his budget is less than or equal to 3.5 gigabytes

Answer:

The answer is 4√3

The measure of the longer side is equal to 4√3

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a² + b² = c².

Given here breadth = 4 and diagonal = 8 and we know that rectangle has all four right angles

Thus, using the Pythagoras theorem we get

length = [tex]\sqrt{8^{2}-4^{2} }[/tex]

          = [tex]\sqrt{64-16}[/tex]

          = [tex]\sqrt{48}[/tex]

          =4 [tex]\sqrt{3}[/tex]

Hence the length of the longer side is  4√3

The sum of the first 35 terms will be 3885.

The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmetic progression

A number series is a number-based sequence. In the number series questions, we must identify the rules that lead to the formation of a number series.

Given that the series is 9, 15, 21, ..., The 35th term of the sequence will be calculated as,

Sn = n /2 [ ( 2a + ( n - 1 ) d]

Sn = 35 / 2 [ ( 2 x 9 + ( 35 - 1 ) 6)]

Sn = 35 /2 { 18 + ( 34 x 6 ) ]

Sn = 35 / 2 x 222

Sn = 3885

Hence, the sum of the 35 terms of the series will be 3885.
