Given that r= 2p2/q-3 ; rearrange the formula to make q the subject of the formula.

Vesnalui [34]

Step-by-step explanation:

The given expression is:

$r=\dfrac{2p^2}{q-3}$

We need to solve it to make q the subject of the formula.

Cross multiplying both sides,

$rq-3r=2p^2$

Adding 3r to both sides,

$rq-3r+3r=2p^2+3r\\\\rq=2p^2+3r$

Now, dividing both sides by r,

$q=\dfrac{2p^2+3r}{r}$

Hence, this is the required solution.

What is the area of the sector shown

EastWind [94]

Answer:

$D.~ 34.2~cm^2$

Step-by-step explanation:

An arc measure of 20 degrees corresponds to a central angle of 20 degrees.

Area of sector of circle

$area = \dfrac{n}{360^\circ}\pi r^2$

where n = central angle of circle, and r = radius

$area = \dfrac{20^\circ}{360^\circ}\pi (14~cm)^2$

$area = \dfrac{1}{18}(3.14159)(196~cm^2)$

$area = 34.2~cm^2$

What is the slope of a line perpendicular to the line whose equations is x-y=6

belka [17]

Answer:

m = -1

Step-by-step explanation:

First write the line in slope intercept form y = mx+b where m is the slope and b is the y intercept

x-y = 6

subtract x from each side

-y = -x+6

Multiply each side by -1

y = x-6

The slope is 1

Perpendicular lines have slopes that multiply to -1

m * 1 = -1

m = -1

The slope of the perpendicular line is -1

Tripp and Rico are two dogs. Tripp weighs exactly 35 pounds more than Rico. Together, they weigh exactly 49 pounds. How much doe

babymother [125]

Call the weights of the two dogs $t$ and $r$ .

We know that Tripp weights 35lbs more than Rico, or:
$t=r+35$

We also know that the total weight of both dogs is 49lbs.:
$t+r=49$

Now, by substitution:
$(r+35)+r=49$
$2r+35=49$
$2r+35-35=49-35$
$2r=14$
$r=\frac{14}{2}$
$r=7$
Rico weighs 7lbs.

Then:
$t=r+35$
$t=7+35$
$t=42$
Tripp weighs 42lbs.

To check our work:
$t+r=49$
$42+7=49$
$49=49$ CHECK!
