Answer:

q= -ck+dp/

-k+d

Step-by-step explanation:

Step 1:

Multiply both sides by p.

dp=ck−kq+pq

Step 2:

Flip the equation.

ck−kq+pq=dp

Step 3:

Add -ck to both sides.

−kq+pq=−ck+dp

Step 4:

Factor out variable q.

q(−k+p)=−ck+dp

Step 5:

Divide both sides by -k+p.

q= -ck+dp/

-k+d

To find the volume,we would first need to find the height of square pyramid, by it's base edge and slant height using Pythagoras theorem:

${height }^{2} = {13}^{2} - {10}^{2} \\ {height }^{2} = 69 \\ height = \sqrt{69}$

We can then use the pyramid formula to find the volume:
$base \: \times \: height \: \times \frac{1}{3}$

In this case,the volume will be:

10×_/69×1/3
=27.68874...
≈27.7 units^3

Hope it helps!

In an intro stats class, 57% percent of students eat breakfast in the morning and 80% of students floss their teeth. Forty-six p

WINSTONCH [101]

Answer: B. 11%

Step-by-step explanation:

Let A = Event that students eat breakfast in the morning.

B= Event that students floss their teeth.

We are given P(A)=57%=0.57

P(B)=80%=0.80

P(A∩B) = 46% =0.46

Now, the probability that a student from this class eats break feast but does not floss their teeth :-

$P(A-B)=P(A)-P(A\cap B)\\\\ = 0.57-0.46=0.11=11\%$

Hence, the probability that a student from this class eats break feast but does not floss their teeth= 11%

What is an equation in point- slope form for the line perpendicular to y= 3x-4 that contains (7,2)?

3241004551 [841]

Answer:

y - 2 = - $\frac{1}{3}$ (x - 7)

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 4 ← is in slope- intercept form

with slope m = 3

Given a line with slope m then the slope of a line perpendicular to it is

$\frac{m}{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{3}$

The equation of a line in point- slope form is

y - b = m(x - a)

m is the slope and (a, b) a point on the line

Here m = - $\frac{1}{3}$ and (a, b) = (7, 2), thus

y - 2 = - $\frac{1}{3}$ (x - 7) ← equation of perpendicular line
