No she is not correct
80 x.70 is 56 as you wrote, and it says 70% wait LESS THAN 30 minutes
On the left of the graph, time, you go to 30 minutes and the patients are much less (21) than 56 patients

You are going to buy some cable television ads. You can get 20 spots for $1200 or 80 spots for $3200 what is the percentage disc

Lesechka [4]

Answer:

33 1/3%

Step-by-step explanation:

When you buy 20 ads, the per-ad rate is

$1200/20 = $60 . . . per ad

When you buy 80 ads, the per-ad rate is

$3200/80 = $40 . . . per ad

The percentage change to the $60 price is ...

((new price) - (original price))/(original price) × 100%

= ($40 -$60)/$60 × 100% = -20/60 × 100%

= -1/3 × 100% = -33 1/3%

The higher volume purchase comes with a 33 1/3% discount.

If a man travels p hours at an average rate of q miles per hour, and then r hours at an average rate of s miles per hour, what i

QveST [7]

Total miles traveled in p hours = p*q miles and
Total miles traveled in r hours = r*s miles
so, average rate of speed = total miles traveled / number of hours
=[{(p*q)+(r*s)} / (p+r)] miles per hour

Someone please help, its for a hw assignment I have due today. What is the equation of the line through (3, 7) that is perpendic

Brilliant_brown [7]

The required equation is:

$y=-\frac{6}{5}x+\frac{53}{5}$

Step-by-step explanation:

Let l_1 be the line through (-1, -2) and (5, 3)

and l_2 be the line we require which passes through (3,7)

We have to find the lope of l_1 first

$m_1=\frac{y_2-y_1}{x_2-x_1}\\=\frac{3-(-2)}{5-(-1)}\\=\frac{3+2}{5+1}\\=\frac{5}{6}$

we have to find the equation of line perpendicular to l1

The product of slopes of two perpendicular lines is -1

Let m_2 be the slope of l_2

Then

$\frac{5}{6}*m_2=-1\\m_2=-\frac{6}{5}$

The general slope-intercept form is:

y=mx+b

Putting the value of slope

$y=-\frac{6}{5}x+b$

To find the value of b, we will put (3,7) in the equation

$7=-\frac{6}{5}(3)+b\\7=-\frac{18}{5}+b\\b=7+\frac{18}{5}\\b=\frac{35+18}{5}\\b=\frac{53}{5}$

Putting the values of b and m in standard slope intercept form:

$y=-\frac{6}{5}x+\frac{53}{5}$

Hence,

The required equation is:

$y=-\frac{6}{5}x+\frac{53}{5}$

Help me please anyone.......

Nonamiya [84]

Answer:

R = 3.6

A = 2

Step-by-step explanation:

R is inversely proportional to A

....which means that....

; R = k/A.....(where k is a constant that does not change)....

;If R = 12 and A = 1.5....then k = 18..

obtain k,by substituting the values into the equation...k = RA

a) If A = 5....then R = 18/5....

; Ans..., R = 3.6

b) If R = 9....then A = 18/9

;Ans..., A = 2
