It has taken me 32 minutes to drive 48 km. If the total length of my journey is 146 km and I maintain the same speed, estimate how much longer I will be driving for. this is my questions its muliple choice, the answer ive come to is 1h 25m but thats not one of the answers to chose from what do i do?
If the total length of the journey is 146 km and he maintain the same speed, the longer time he will be using for driving will be 65m.
How can the time be calculated?The total length of my journey is 146 km.
Then the remain of the journry to reach 146 km = 146- 48 = 98
Then the if the same speed is maintained the estimate of longer time he will be using for driving will be calculated as :
(32 * 98)/48
Then get the productor quotient = 196/3 = 65 minutes
Therefore, option E is correct.

Answer:
Rate of change= 1/3
Initial value = -4
Step-by-step explanation:
The rate of change is rise/run = 1/3.
the initial value is the y-intercept which is -4.
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality
however, is the same cat wearing different costumes.
to get the slope of any straight line, we simply need two points off of it, let's use those two in the picture below
[tex](\stackrel{x_1}{-6}~,~\stackrel{y_1}{-6})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{-3}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{-3}-\stackrel{y1}{(-6)}}}{\underset{\textit{\large run}} {\underset{x_2}{3}-\underset{x_1}{(-6)}}} \implies \cfrac{-3 +6}{3 +6} \implies \cfrac{ 3 }{ 9 } \implies \cfrac{1 }{ 3 }[/tex]
now as far as the "initial value", dunno what that means.
The start of the line? well, the line by definition goes to infinity both ways.
the y-intercept? well, just look at the graph, the graph intercepts the y-axis when x = 0 and y = -4, so at (0 , -4).

Your wealth increases more quickly due to compound interest. Due to the fact that you will receive returns on both the money you invest and returns at the conclusion of each compounding period, it causes a sum of money to increase more quickly than with simple interest. As a result, you won't need to save as much money to achieve your objectives.

(b) (1, -2pi/3)
(c) (-1, 5pi/4)
Answer:
The other pairs are:
[tex](a)\ (2, \frac{5\pi}{6}) \to[/tex] [tex](2, \frac{17\pi}{6})[/tex] and [tex](-2, \frac{23\pi}{6})[/tex]

See attachment for plots
Step-by-step explanation:
Given
[tex](a)\ (2, \frac{5\pi}{6})[/tex]
[tex](b)\ (1, -\frac{2\pi}{3})[/tex]
[tex](c)\ (-1, \frac{5\pi}{4})[/tex]
Solving (a): Plot a, b and c
See attachment for plots
Solving (b): Find other pairs for [tex]r > 0[/tex] and [tex]r < 0[/tex]
The general rule is that:
The other points can be derived using
[tex](r, \theta) = (r, \theta + 2n\pi)[/tex]
and
[tex](r, \theta) = (-r, \theta + (2n + 1)\pi)[/tex]
Let [tex]n =1[/tex] ---- You can assume any value of n
So, we have:
[tex](r, \theta) = (r, \theta + 2n\pi)[/tex]
[tex](r, \theta) = (r, \theta + 2*1*\pi)[/tex]
[tex](r, \theta) = (r, \theta + 2\pi)[/tex]
[tex](r, \theta) = (-r, \theta + (2n + 1)\pi)[/tex]
[tex](r, \theta) = (-r, \theta + (2*1 + 1)\pi)[/tex]
[tex](r, \theta) = (-r, \theta + (2 + 1)\pi)[/tex]
[tex](r, \theta) = (-r, \theta + 3\pi)[/tex]
[tex](a)\ (2, \frac{5\pi}{6})[/tex]
[tex]r = 2\ \ \ \ \theta = \frac{5\pi}{6}[/tex]
So, the pairs are:
[tex](r, \theta) = (r, \theta + 2\pi)[/tex]
[tex](2, \frac{5\pi}{6}) = (2, \frac{5\pi}{6} + 2\pi)[/tex]
Take LCM
[tex](2, \frac{5\pi}{6}) = (2, \frac{5\pi+12\pi}{6})[/tex]
[tex](2, \frac{5\pi}{6}) = (2, \frac{17\pi}{6})[/tex]
And
[tex](r, \theta) = (-r, \theta + 3\pi)[/tex]
[tex](2, \frac{5\pi}{6}) = (-2, \frac{5\pi}{6} + 3\pi)[/tex]
Take LCM
[tex](2, \frac{5\pi}{6}) = (-2, \frac{5\pi+18\pi}{6})[/tex]
[tex](2, \frac{5\pi}{6}) = (-2, \frac{23\pi}{6})[/tex]
The other pairs are:
[tex](2, \frac{17\pi}{6})[/tex] and [tex](-2, \frac{23\pi}{6})[/tex]
[tex](b)\ (1, -\frac{2\pi}{3})[/tex]

So, the pairs are:
[tex](r, \theta) = (r, \theta + 2\pi)[/tex]

9514 1404 393
Answer:
A (-2), A
Step-by-step explanation:
A function will have a point of discontinuity at a point where it is undefined. Rational functions will be undefined where the denominator is zero. This function will have denominator zeros at x = -2, so is discontinuous there.
__
As x approaches -2 from either direction, the value of y approaches positive infinity. The type of discontinuity can be described as an infinite discontinuity.

Therefore , the solution of the given problem of percentage comes out to be 4250 mg, or 4.25 g and the percentage increase is 50%.
A percentage is what?A% is a number that can be expressed as a decimal or a fraction and indicates what proportion of 100 it is. Put 100 in the denominator and the percentage amount in the numerator to turn a percentage into a fraction.
Here,
This "Nutritional Facts" table indicates that 85 mg of potassium, or 2% of the daily recommended value, corresponds to the row "Potassium".
By using the unitary method, (85/2) mg of potassium will represent 1% of the daily required intake.
As a result, 4250 mg of potassium, or 100% of the daily allowance, will be required: (85/2 * 100).
The entire quantity of potassium that is advised for daily consumption is 4250 mg, or 4.25 g.
(New value) − (Initial value) / (Initial value) = percent change. * 100%.
Here,
Initial value: $1.50 (the 1995 fare).
New value equals $2.25 for the 2008 fare.
Therefore,
percentage variation
= [(2.25 - 1.50) / 1.50] .50] * 100%
= (0.75 / 1.50) * 100%
= 0.5 * 100%
= 50%.
Positive indications of the transition point to an increase in fare.
The percentage increase is therefore 50%.

Sam rolls a fair dice and flips a fair coin.
What is the probability of obtaining an odd number and a head?
There are six sides to a die and only one side has a two, so the probability of rolling a 2 is 1/6.
There are two sides to a coin and only one side has a head, so the probability of its coming up heads is 1/2.
The two events (rolling a die and flipping a coin) are independent, so the probability of both events occurring is (1/6)(1/2) = 1/12

For each outcome, there is probability 1/16.
The numbers at the right show the number of yellows for each outcome. There are 9 outcomes with 0 yellow (prob = 9/16).
There are 6 outcomes with 1 yellow (prob = 6/16)
There is 1 outcome with 2 yellow (prob = 1/16)
Hence, because the calculated values are consistent with the values in the first table, then we can conclude that the first table is correct.

So the key is that a line has a measure of 180 degrees. Notice the square between the rays. That is a 90-degree angle. So let's add this up and see what's going on
[tex](5p + 2) + 90 + (7p + 4) = 180[/tex]
[tex]12p + 96 = 180[/tex]
[tex]12p = 84[/tex]
[tex]p = 7[/tex]
Answer:
p = 7
Step-by-step explanation:
From the diagram, we can see that all the angles given form a straight line, and therefore add up to 180°.
We can create an equation with what is given:
***The angle with the square marked is 90°.
5p° + 2° + 90° + 7p° + 4° = 180°
You can combine the like terms, getting:
12p° + 96° = 180°
Now, subtract 96° from both sides:
12p° = 84°
Now, divide by 12°, and get:
p = 7
For every boy taking classes at the music school, there are 3 girls who are taking classes at the school. If there are 128 students taking classes, write and solve a proportion to predict the number of girls taking classes at the school.
Answer:
There are 96 girls taking classes at the music school, while the number of boys is 32.
Step-by-step explanation:
Since for every boy taking classes at the music school, there are 3 girls who are taking classes at the school, if there are 128 students taking classes, for write and solve a proportion to predict the number of girls taking classes at the school you must perform the following calculation:
1 + 3 = 4
128/4 x 3 = Girls
32 x 3 = Girls
96 = Girls
Therefore, there are 96 girls taking classes at the music school, while the number of boys is 32.
