Answer:

The Answer would be $40.64

Step-by-step explanation:

To find a percentage of a certain number, you must multiply that number by the percentage in decimal form. Since the socks cost 8 dollars each 8 x 0.08 = 0.64 Meaning the tax cost is 64 cents. 8 x 5 = 40 Giving us $40.64

Answer:

13.3041346957 Ft. ( Or 13.30 Ft. )

Step-by-step explanation:

Formula: A^2 + B^2 = C^2

Substitution: 9^2 + 6^2 = 117

√177 = 13.3041346957

13.3041346957 ( Rounded ( Hundredths Place ) = 13.30 Ft .

Answer:

(B) 18

Step-by-step explanation:

The shape is fliped but when put to the point where the shapes look the same QP is congruent to DE. Shape DEFG is 2 times bigger than shape PQRS. So all the line measures on PQRS are 2 times smaller than those on DEFG. Meaning x or QP is equal to 18 since 36 divided by 2 is 18.

Hope this helped :)

Step-by-step explanation:

y = x^2 + 2x - 15

To find the x-intercepts, factor out the right side:

y = x^2 + 2x - 15

= (x + 5)(x - 3)

This means that the x-intercepts are at (-5, 0) and (3, 0).

Method 1:

The x-coordinate of the vertex of a parabola is given by the following:

x = -b/2a, where a = 1 and b = 2

= -(2/(2×1))

= -1

Using this value of x gives y = -16

Therefore, the coordinates of the vertex is (-1, -16).

Method 2:

We can find the x-coordinate of the vertex by taking the derivative of y and equating it to zero:

y' = 2x + 2 = 0 ---> x = -1

Using this value of x into our equation, we get y = -16.

Therefore,

vertex: (-1, -16)

Answer:(133,157)

Step-by-step explanation:

Using the empirical rule, the interval that would represent the middle 68% of the scores of all the games that Avani bowls is (133, 157).

Empirical rule is a rule for normally distributed data which defines that almost all the data observed ranges between three standard deviations from the mean.

Here, the scores of Avani is normally distributed.

Mean, μ = 145

Standard Deviation, σ = 12

By the Empirical rule, about 68% of the data falls within one standard deviation.

That is, in the interval μ ± σ.

Interval is (μ - σ, μ + σ) = (145-12, 145+12) = (133, 157)

Hence the interval is (133, 157).

Answer: 437,500 copies

Step-by-step explanation:

42,000 copies were sold in the first month and this is 9.6% of the total that have been sold till date:

To find the total that have been sold till date, assume the amount to be x.

Expression will be:

9.6%x = 42,000

x = 42,000 / 9.6%

x = 42,000 / 0.096

x = 437,500 copies

437,500 copies have been sold to date.
