48 less than twice a number

Answer:

First, you have to factorize the expressions :

[tex] \frac{5x + 20}{8 {x}^{5} } \times \frac{x}{ {x}^{2} - 16} [/tex]

[tex] = \frac{5(x + 4)}{8 {x}^{5} } \times \frac{x}{(x + 4)(x - 4)} [/tex]

Second, you have to cross out the similar expressions :

[tex] = \frac{5}{8 {x}^{5} } \times \frac{x}{(x - 4)} [/tex]

Third, you have to multiply both fractions :

[tex] = \frac{5x}{8 {x}^{5}(x - 4) } [/tex]

Lastly, you have to simplify :

[tex] = \frac{5}{8 {x}^{4}(x - 4) } [/tex]

Answer:

The answer is 1 or A.

Step-by-step explanation:

The difference in the formula of population and sample variance can be explained as:

Population variance is said to be the value of variance that is calculated from population data, whereas sample variance refers to the variance calculated from sample data. This is the reason why value of denominator in the formula for variance in case of sample data is ‘n-1’, while it is ‘n’ for population data. Hence, the result of both variance and standard deviation derived from sample data is larger than those found out from population data.

Answer:

88.89%

Step-by-step explanation:

Step one:

given

a man buys eggs at RS 9.60 per dozen

what is the unit cost of the dozen of eggs?

unit cost = 9.60/12

= $0.8 per egg

He sold 20 eggs for RS 18

the unit selling price = 18/20

=$0.9 per egg

the percent gain is

=0.8/0.9*100

=0.888*100

=88.89%

Answer:

∠C (Interior) =78°

∠B (Interior) = 62°

Step-by-step explanation:

Given:

∠A (Interior) = 40°

∠C (exterior) = 102°

Computation:

∠C (Interior) = 180° - 102°

∠C (Interior) =78°

∠B (Interior) = 180° - ∠A (Interior) - ∠C (Interior)

∠B (Interior) = 180° - 78° - 40°

∠B (Interior) = 180° - 118°

∠B (Interior) = 62°

Answer:

0.2496

Step-by-step explanation:

what you could do is make the all the 1/5 into 2/10's.

then you could multiply all of them (2/10) squared (2/10) cubed and (2/10)^4

now you would have 2/10 4/100 8/1000 16/10000

now you can change it into decimals and add

0.2 +0.04+0.008+0.0016

now all you have to do is add when you do you get 0.2496

there are many ways you could do this problem but this is the most efficient becuause I used another way but it was not helpfull.  

Answer: .2496

Aops Question

Step-by-step explanation:

This problem becomes easier if we write $\dfrac{1}{5}$ as $\dfrac{2}{10}$, so that all the denominators in our sum are powers of 10. Then

\begin{align*}

\frac15 + \left(\frac15\right)^2 + \left(\frac15\right)^3 + \left(\frac15\right)^4

&= \frac2{10} + \left(\frac2{10}\right)^2 + \left(\frac2{10}\right)^3 + \left(\frac2{10}\right)^4 \\

&= \frac2{10} + \frac4{100} + \frac8{1000} + \frac{16}{10{,}000} \\

&= 0.2 + 0.04 + 0.008 + 0.0016 \\

&= \boxed{0.2496}.

\end{align*}

Answer:5

Step-by-step explanation:

If you look at the question in reverse you can backtrack your way through. Take 10 and instead of dividing, multiply it by 10, which is 60, add 6 instead of subtracting, which is 66, divide by 6 instead of multiplying, which is 11 and finally subtract 6 instead of adding, which is 5. Use five and try the question over to make sure you calculated correct.

Using translation concepts, the functions are given as follows:

1. F(x) = x² - 9x + 8.

2. [tex]G(x) = x^{19} + 8x^6 - x^5 - 7x^2 + x - 9[/tex]

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

In item 1, the function is:

f(x) = x² + 9x + 8.

When the function is reflected over the y-axis, we have that:

F(x) = f(-x),

Hence:

F(x) = (-x)² + 9(-x) + 8.

F(x) = x² - 9x + 8.

For item 2, the function is:

[tex]g(x) = x^{19} - 8x^6 - x^5 + 7x^2 + x + 9[/tex]

When the function is reflected over the x-axis, we have that:

G(x) = -g(x).

Hence:

[tex]G(x) = -x^{19} + 8x^6 + x^5 - 7x^2 - x - 9[/tex]

When the function is reflected over the y-axis, we have that:

Hence:

G(x) = G(-x).

[tex]G(x) = -(-x)^{19} + 8(-x)^6 + (-x)^5 - 7(-x)^2 - (-x) - 9[/tex]

[tex]G(x) = x^{19} + 8x^6 - x^5 - 7x^2 + x - 9[/tex]

The equation for the given phrase "Six-sevenths of y is 60" is (6/7) × y = 60 and its solution for y is 70.

According to the given question.

We have a phrase " Six-sevenths of y is 60".

The equation for the above phrase "Six-sevenths of y is 60" is given by

(6/7) × y = 60

Now we have a linear equation in one varibale.

Thereofore, the solution of the equation (6/7) × y = 60 for y is given by

(6/7) × y = 60

⇒ 6y = 60 × 7        (multiplying both the sides by 7)

⇒ 6y = 420

⇒ y = 70

Hence, the equation for the given phrase "Six-sevenths of y is 60" is

(6/7) × y = 60 and its solution for y is 70.

The point-slope intercept equation is y - 20 = 3/4(x - 4).

The rate of change is 3/4.

At 0 months (at birth), Grace was 17 inches long.

At 36 months, Grace would be 44 inches long.

A linear equation of a graph can be represented in point-slope form as y - b = m(x - a), where (a, b) is a point on the graph and m is the slope.

Find the Slope (m) using two points (4, 20) and (8, 23):

Slope (m) = change in y/change in x = (23 - 20)/(8 - 4)

Slope (m) = 3/4

Substitute (a, b) = (4, 20) and m = 3/4 into y - b = m(x - a):

y - 20 = 3/4(x - 4) [point-slope intercept equation]

At birth, months would be x = 0. To find how long Grace was at birth, substitute x = 0 into y - 20 = 3/4(x - 4) to find the value of y:

y - 20 = 3/4(0 - 4)

y - 20 = 3/4(-4)

y - 20 = -3

y - 20 + 20 = -3 + 20

y = 17

This means that, at 0 months (at birth), Grace was 17 inches long.

At 36 months, substitute x = 36 into y - 20 = 3/4(x - 4) to find the how long Grace was (y):

y - 20 = 3/4(36 - 4)

y - 20 = 3/4(32)

y - 20 = 24

y - 20 + 20 = 24 + 20

y = 44

At 36 months, Grace would be 44 inches long.

Given:

The bakers at Healthy Bakery can make 170 bagels in 2 hours.

To find:

How many  bagels can they bake in 14 hours and the rate per hour.

Solution:

We have,

Number of bagels the bakers can bake in 2 hours = 170 bagels

Number of bagels the bakers can bake in 1 hours = [tex]\dfrac{170}{2}[/tex] bagels

                                                                                   = 85 bagels

Therefore, the average rate is 85 bagels per hour.

Number of bagels the bakers can bake in 14 hours = [tex]14\times 85[/tex] bagels

                                                                                    = 1190 bagels

Therefore, the bakers can bake 1190 bagels in 14 hours.
