Jim's family went on vacation and rented a car. The rental car agency charged $64.75 plus an additional $0.03 for each mile the car was driven. If Jim's family paid a total of $71.14 for the car rental, how many miles did the family drive the car? Explain how you set up an equation to solve this word problem

Answers

Answer 1
$71.14 - $64.75 = $6.39
Each mile = $0.03
$6.39 ÷ $0.03 = 213 miles.

Find the smallest value of k if 264k is a perfect square

Answers

Try factoring this first.
264k = 132*2k = 11*12*k = 11*3*2*2*k 
To get a perfect square, you are going to have to have an even number of prime factors. 
You have one 11 and one 3. You are going to have to do something about those two.
k = 11 * 3 <<<<< ======= answer.

Now put that into 264k and you get 11 * 3 * 2 * 2 * 11 * 3 which is a perfect square. 11^2 * 3^2 * 2^2 = 4356

The square root of 4356 = 66 
4356 is a perfect square when 33 = k.

What is the measure of ∠A?


What is the measure of ∠B?

Answers

The opposite angles of a parallelogram are equal.
Therefore
m∠A = m∠C, so that
5y - 3 = 3y + 27
Subtract 3y from each side.
5y - 3y - 3 = 3y - 3y + 27
2y - 3 = 27
Add 3 to each side.
2y - 3 + 3 = 27 + 3
2y = 30
y = 30/2 = 15

Therefore
m∠A = 5*15 - 3 = 72°
m∠C = 72°

Let x = m∠B
Then x = , m∠B = m∠C
Because the sum of the angles in the parallelogram is 360°, therefore
x + x + 72 + 72 = 360
2x = 360-144 = 216
x = 216/2 = 108

Select the correct factor from the presentation and calculate how many calories used. (Round to the hundredths.) A person weighing 165 lbs. jogs 1 mile in 8 minutes. How many calories used?
A. 102.30
B. 107.25
C. 253.85
D. 266.13

Answers

Answer:

the answer is 107.25              

Step-by-step explanation:


Answer:

B. 107.25

Step-by-step explanation:

Let x be the calories burnt by the man,

Since, when a person runs 1 miles in 8 minutes,

Then,

[tex]\frac{\text{Calories used by him}}{\text{His weight in lb}}=65\%[/tex],

Given,

Weight of the person = 165 lb,

Thus,

[tex]\frac{x}{165}=\frac{65}{100}[/tex],

[tex]x = \frac{165\times 65}{100}[/tex]

[tex]x=\frac{10725}{100}[/tex]

[tex]\implies x=107.25[/tex]

Hence, 107.25 calories will be used.

Which equation has the graph that is a parabola with a vertex at 5,3

Answers

We can solve this using vertex form of a parabola:
[tex]y=a(x-h)^2+k[/tex]
In our case h=5 and k=3, these are coordinates of our vertex point. 
There is no way to find a without knowing any other coefficients.
When you start solving some equations to get the parameters you always end up with identity (example 25=25). This means that your equation has an infinite number of solutions. In other words, any a will give you a parabola with vertex at the specified point.
The final answer would:
[tex]y=a(x-5)^2+3[/tex]
Where a is any real number.

scatter plot with points loosely scattered going down to the right

Answers

Scatterplots are a useful way of visualizing statistical data and to draw some quick conclusions from the data. Each scatterplot is unique but there are some common trends about association of the 2 variables that can be applied. In a scatterplot with an upward trend, we would say that the variables have a positive association or that they have a positive correlation. When one variable increases, the other increases too (in general). If the plot has a downward trend, we talk of a negative association. Finally, there could also be no association, with plot points scattered all around. Thus, in this case, we have negative correlation. If there is anything else you need regarding this answer, comment.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

The triangle ∆MTW is congruent to the triangle ∆CAD. Then we have

∠MTW ≅ ∠CAD

∠TWM ≅ ∠ADC

v=√324-6---------> 18-6=12
v=12

the answer is v=12

Answer:

The values of v in increasing order are, -24, 12

Step-by-step explanation:

Given equation is,

[tex](v+6)^2=324[/tex]

[tex]v+6=\pm 18[/tex]

[tex]v=-6\pm 18[/tex]

[tex]\implies v=-6-18\text{ or }v=-6+18[/tex]

A employer, who started a new business, has promised his employees a minimum starting wage of $3, with an increase of $2 every 4 years. Sketch a graph of wage as a function of time for 16 years. Assume the wages take effect at the beginning of the year where the change is made. (HINT: use a step function to represent the function.)

Answers

This is a step function because it increases in "steps".  The wage stays constant for a 4 year period, then jumps by $2 instead of a steady increase.
Final answer:

To sketch the graph, use a step function to represent the wage as a function of time over 16 years. The minimum starting wage is $3, and it increases by $2 every 4 years.

Explanation:

To sketch a graph of wage as a function of time for 16 years, we can use a step function to represent the function.

The minimum starting wage is $3 and it increases by $2 every 4 years. For the first 4 years, the wage will be $3. At the start of the 5th year, the wage will increase to $5. This pattern continues, with the wage increasing by $2 every 4 years.

So, the graph will have flat lines representing each 4-year interval, with a step up at the start of each interval.

Marie earns $96 in interest each year on an investment what is the rate of simple interest if her principal was $800

Answers

[tex]\bf ~~~~~~ \textit{Simple Interest Earned}\\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\to &\$96\\ P=\textit{original amount deposited}\to& \$800\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\to &\stackrel{each~year}{1} \end{cases} \\\\\\ 96=800(r)(1)\implies \cfrac{96}{800}=r \\\\\\ 0.12=r\implies r\%=100\cdot 0.12\implies r=\stackrel{\%}{12}[/tex]

The rate of simple interest that Marie earns on her $800 investment is 12% per year, calculated by dividing the annual interest earned ($96) by the principal amount ($800).

To find the rate of simple interest, we can use the formula Interest = Principal * rate * time. Given that Marie earns $96 in interest each year on an investment and her principal was $800, we can rearrange the formula to solve for the rate.

The formula for simple interest is:

Interest = Principal * rate * time

Assuming the interest earned is for one year, we have:

$96 = $800 * rate * 1 year

To find the rate, we divide both sides by $800:

rate = $96 / $800

rate = 0.12

Converting into a percentage, the simple interest rate is 12% per year.

Q: You're driving down the highway late one night at 16m/s when a deer steps onto the road 44m in front of you. Your reaction time before stepping on the brakes is 0.50s , and the maximum deceleration of your car is 10m/s2 .

How much distance is between you and the deer. I solved this =23m

What is the maximum speed you could have and still not hit the deer?

The answer is 25 m/s. A lot of people had stated to use the quadratic formula. I just don't know where to begin.

Answers

I don't know why you need the quadratic formula.  

If it takes 0.5 seconds before stepping on the breaks while going 16 m/s, then you travel 8 meters before anything happens. That means you are 44-8 = 36 meters away from the deer now. 
 v^2 = v_initial^2 + 2(acceleration)(distance)
 0 = (16 m/s)^2 + 2(-10m/s^2)(distance)
 256 m^2/s^2 / (2(10 m/s^2) = distance = 12.8 meters (13 meters after significant figures are taken into account). 
 The maximum speed would be: 
 0 = v_initial^2 + 2(-10m/s^2)(36m)
 v_initial^2 = 720m^2/s^2
 v_initial = 27 mph

Given : X divides into the line PQ in the ratio 2:3 P is (2,1) and Q is (12.5,7.5).

Then, coordinate of X is given by :-
