1dozen=12

$\\ \rm\Rrightarrow \dfrac{2}{3}\:of\:\dfrac{4}{5}\:of\:12$

$\\ \rm\Rrightarrow \dfrac{2}{3}\times \dfrac{4}{5}\times 12$

$\\ \rm\Rrightarrow \dfrac{96}{15}$

$\\ \rm\Rrightarrow \dfrac{32}{5}$

$\\ \rm\Rrightarrow 6.4$

Determine which line is perpendicular to y = - 7/5x-2.

tatuchka [14]

Answer:

y = 5/7 x - 6

Step-by-step explanation:

For two lines to be perpendicular, the product of their slope must be -1

The slope of the given function is -7/5

Let the slope of the required function be m

m * -7/5 = -1

7/5 m = 1

7 = 5m

m = 5/7

The slope of the line perpendicular to the line is 5/7

The required equation (using any value of the y-intercept) is expressed as;

y = 5/7 x - 6

Note that the y-intercept value was assumed and any value can be used

How do you solve what is 30% of $240

DerKrebs [107]

The Answer would be x=72. Why? Because $\frac{x}{240} = \frac{30}{100}. Fraction \frac{30}{100}$ is your %. You Cross multiply 240 * 30 = 100x
240 time 30 = 7200. you want x to be alone so you do 7200 divided by 100 equaling 72. So you get x=72.

3. If x +4, 2x+5, and 4x +3 represent the first three terms of an arithmetic sequence, then find the

solong [7]

first term = initial number

second term = initial number + common difference

third term = initial number + 2(common difference)

So...

2x+5-(x+4) = common difference

4x+3-(2x+5) = also common difference

2x+5-(x+4) = x+1

4x+3-(2x+5) = 2x-2

Because x+1=2x-2 we can solve for x.

x=3

So the sequence goes... 7,11,15...

19 is the fourth term
