Answer:

The speed of car in miles per minute is  \frac{2}{3} miles per minute and

The speed of car in mile per hour is 40 miles per hour,

Step-by-step explanation:

Given as :

The distance cover by car = 2 \frac{1}{3} = \frac{7}{3} miles

The Time taken by car to cover distance =  3 \frac{1}{2} min =  \frac{7}{2} min

The speed o car in miles per minute = S miles/min

So, Speed = \dfrac{\textrm Distance}{\textrm Time}

Or, S = \frac{\frac{7}{3}}{\frac{7}{2}} mie per min

∴  S = \frac{2}{3} miles per minute

Now, Let The speed of car in miles per hour = x miles/h

So, Time in hour = \frac{7}{2} × \frac{1}{60} = \frac{7}{120} hours

So ,  Speed = \dfrac{\textrm Distance}{\textrm Time}

Or, x = \frac{\frac{7}{3}}{\frac{7}{120}} miles per hours

Or, x = 40 miles per hours

Hence The speed of car in miles per minute is  \frac{2}{3} miles per minute and the speed of car in mile per hour is 40 miles per hour, answer

Plisss help write the linear equation that vives the rule for this table ​
sineoko [7]

well, we know is a line,  and to get the equation of any straight line all we need is two points, hmmm let's use from the table hmm say (2 , -50) and hmmm (4 , -88)

(\stackrel{x_1}{2}~,~\stackrel{y_1}{-50})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-88}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-88}-\stackrel{y1}{(-50)}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{2}}}\implies \cfrac{-88+50}{2}\implies \cfrac{-38}{2}\implies -19

\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-50)}=\stackrel{m}{-19}(x-\stackrel{x_1}{2}) \\\\\\ y+50=-19x+38\implies y=-19x-12

Lesson 2.7:
1) / divide 195 by 18 to get 10.833.
/ to get the whole number, round up to get '11'.
11 cartons


Lesson 2.8:
3) 
588 ÷ 84 = 7
5) 6,681 ÷ 53 = 126 with a remainder of 3

Lesson 2.9:
1) / let 'x' equal the inches of snow that reidville gets
/ '12x' equal the inches of snow that greenboro gets
/ you should set up the problem like: x + 12x = 65
/ add 'x + 12x' to get '13x'. 
/ divide both sides by '13'.
/ 5 goes into 13 to get 65. simplify the fraction to '5'.
/ x = 5
Reidville gets 5 inches of snow

2) / let 'x' equal the miles ansley ran in one month
/ you should set up the problem like: 15x + x = 192
/ add '15x + x' to get '16x'
/ divide both sides by '16'
/ 12 goes into 16 to get 192. simplify the fraction to 12.
/ x = 12
Ansley runs 180 miles (Zack only runs 12)

a countrys population in 1992 was 72 million in 1998 it was 76 million estimate the population in 2012 using the exponential gro
crimeas [40]
Hi there
First find the rate of growth between
1992 and 1998
The formula is
P=Ae^rt
P the population in 1998. (76 million)
A the population in 1992 (72 million)
E constant
R rate of growth?
T time 1,998−1,992=6 years
We need to solve for r
R=[log (p/A)÷log (e)]÷t
R=(log(76÷72)÷log(e))÷6
R=0.009

Now find the population in 2012
P=Ae^rt
P ?
A 72 million
R 0.009
T 2,012−1,992=20 years
So
P=72×e^(0.009×20)
P=86.2 round your answer to get
P=86 million

Good luck!
