Kiran says “If I walk 3 miles per hour toward you, and you walk 3.4 miles per hour toward me, it’s the same as if you stay put and I jog 6.4 miles per hour.” What do you think Kiran means by this? Is he correct?
Answer:
Yes it is the same. Since the total distance left behind per time unit would be the same. Just that He would Do that by himself.

Question Help
Jane took 30 min to drive her boat upstream to water-ski at her favorite spot. Coming back later in the day, at the same boat speed, took her 20 min. If the current in
that part of the river is 4 km per hr, what was her boat speed in still water?
Her boat speed in still water was km per hr.
Answer:
The speed of the boat is 20 km/hr
Step-by-step explanation:
Let s be the speed of boat in still water
Let d be the distance
Upstream speed = s-4
Jane took 30 min to drive her boat upstream to water-ski at her favorite spot.
So, Distance traveled in upstream =[tex]Speed \times time =(s-4) \times \frac{30}{60}[/tex]
Downstream speed = s+4
So, Distance traveled in downstream = [tex]Speed \times time =(s+4) \times \frac{20}{60}[/tex]
So, [tex](s-4) \times \frac{30}{60}=(s+4) \times \frac{20}{60}[/tex]
30s-120=20s+80
10s=200
s=20
Hence The speed of the boat is 20 km/hr
If Megan's tuition, fees, and expenditures for books this year total $19,000, what will they be during her senior year (three years from now),
assuming costs rise 7 percent annually? Round Future value of a Single
Amount in intermediate calculations to four decimal places.
Answer:
$23,275.817
Step-by-step explanation:
To get this answer, multiply 19,000 by 1.07.
$19,000 x 1.07 = 20,330 (one year later)
$20,330 x 1.07 = $21,753.10 (two years later)
$21,753.10 x 1.07= $23,275.817 (three years later)
The answer round to cents would be $23,275.82

Step-by-step explanation:
The distance between Point P and Point Q was 3600 m. Beng Leong started jogging
at 08 35 from Point P and reached Point Q at 08 50. At the same time, Sam started
jogging from Point P at a speed of 200 m/min. Who jogged at a faster speed?
How much faster was his speed?
Answer:
Ben ran at a speed of 240m/min and Sam ran at a speed of 200m/min So Ben is faster by a rate of 40/min
Step-by-step explanation:
Ben's miles per minutes
[tex] \frac{3600}{15} = 240[/tex]
Sam's miles per minute

Identify the focus, directrix, and axis of symmetry of x^2=64y
The general equation represented as: [tex]\mathbf{x^2 = 2py}[/tex]
The focus is [tex]\mathbf{F = (0,16)}[/tex]The directrix is [tex]\mathbf{y = -16}[/tex]The axis of symmetry is [tex]\mathbf{x = 0}[/tex]The equation is given as:
[tex]\mathbf{x^2 = 64y}[/tex]
Recall that:
[tex]\mathbf{x^2 = 2py}[/tex]
Where:
[tex]\mathbf{F = (0,\frac p2)}[/tex] --- the focus
[tex]\mathbf{y = -\frac p2}[/tex] --- the directrix
Compare [tex]\mathbf{x^2 = 2py}[/tex] and [tex]\mathbf{x^2 = 64y}[/tex], we have:
[tex]\mathbf{2py = 64y}[/tex]
Divide both sides by 2y
[tex]\mathbf{p = 32}[/tex]
Recall that:
[tex]\mathbf{F = (0,\frac p2)}[/tex] and [tex]\mathbf{y = -\frac p2}[/tex]
So, we have:
[tex]\mathbf{F = (0,\frac {32}2)}[/tex]
[tex]\mathbf{F = (0,16)}[/tex]
[tex]\mathbf{y = -\frac p2}[/tex]
[tex]\mathbf{y = -\frac{32}{2}}[/tex]
[tex]\mathbf{y = -16}[/tex]
The axis of symmetry is [tex]\mathbf{x = 0}[/tex]

Which phrase describes the geometric interpretation of dividing a complex number z by i?
O Reflect z across the real axis.
O Reflect z across the imaginary axis.
O Rotate z by 90° clockwise about the origin.
O Rotate z by 90° counterclockwise about the origin.
Answer: Rotate z by 90° clockwise about the origin.
Step-by-step explanation:
Suppose we have the number z = a + b*i, that can be represented with the point (a, b) in a coordinate axis.
If we divide z by i, we have:
[tex]\frac{z}{i} = \frac{a + b*i}{i} = \frac{a + b*i}{i} *\frac{i}{i} = \frac{a*i - b}{-1} = b - a*i[/tex]
This point will be represented with the point (b, -a)
Then we have the transformation:
(a, b) ----> (b, -a)
This is a rotation of 90° clockwise about the origin.
Then the correct option is:
Rotate z by 90° clockwise about the origin.
Answer:

Question Help Point C is seven units to the left of the y-axis and five units below the x-axis. Write the ordered pair for point C.
Answer:
C = (-7,-5)
Step-by-step explanation:
Analysing the statements in the question, one after the other.
1. 7 units to the left of y axis
This implies that the x coordinate of C is -7
2. 5 units below the x axis.
This implies that the y coordinate of C is -5)
So,
C(x,y) = C(-7,-5)
Hence, the required coordinates of C is (-7,-5)

Rosa believes she can use a division expression to find the cost per pound of ground beef when 2/3 pound sells for $4. Which statement best explains why Rosa is correct or incorrect? A. Rosa is correct in using a division expression because the term ""per"" implies the quotient of the quantities before and after that word. B. Rosa is correct in using a division expression because the cost per pound should be less than $4. C. Rosa is incorrect in using a division expression because ""cost per pound"" refers to the product of the price and weight. D. Rosa is incorrect in using a division expression because the cost per pound must be an integer.
Answer: A. Rosa is correct in using a division expression because the term ""per"" implies the quotient of the quantities before and after that word.
Step-by-step explanation:
The term ; Cost per pound can be interpreted mathematically to mean;
Cost / pound ; where per means division. In the context above ;
cost per pound = cost of 1 pound of an item ;
(Stated Cost of the item ÷ pound of the item at the stated cost)
For the question above ;
2/3 pounds of ground beef cost $4;
Cost per pound = cost of 1 pound of ground beef ;
= $4 ÷ (2/3)
= $6
Hence, 1 pound of ground beef cost $6

Explanation:
The angles COE, EOF, and FOB combine to form angle COB
angle COB = (angleCOE)+(angleEOF)+(angleFOB)
angle COB = (3x)+(x)+(x+12)
angle COB = 5x+12
----------
Angles AOD and COB are vertical angles, so they are congruent
angle COB = angle AOD
5x+12 = 152
5x = 152-12
5x = 140
x = 140/5
x = 28

The difference of half of a number and three is equivalent to negative five?
Answer:
-7
Step-by-step explanation:
Let the number be represented with 'Y'
Half of the number will be = Y/2
The difference of half of a number and 3
= Y/2 - 3
Is equivalent to negative 5
That is,
Y/2 - 3 = -5
y/2-3/1 = -5/1
Collect like terms
y/2 = -5/1+3/2
y/2 = -7/2
Multiply both sides by 2
y/2 ×2 = -7/2×2
Y = - 7
Hence the number is negative 7

What is the goal of solving equations?
Answer:
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable.
Step-by-step explanation:
The objective or equation would be to acquire the variables independently. A further explanation is provided below.
The objective is to address an expression by getting the component solely on a single side of this argument as well as a figure while on the other side of the same expression.Throughout the order to isolate variables, procedures that influence somewhat on variables have to be reversed. We achieve this by carrying out several halves of the expression the opposite of every process.

Are the measures of Z4 and 214 related in
the same way as the measures of 29 and
Z7? Show your work.
Answer:
Step-by-step explanation:
m∠4 + m∠16 = 180° [Consecutive exterior angles]
m∠16 = m∠14 [corresponding angles]
Therefore, m∠4 + m∠14 = 180°
m∠7 + m∠11 = 180° [Consecutive interior angles]
m∠11 = m∠9 [Corresponding angles]
Therefore, m∠7 + m∠9 = 180°
In both the cases sum of the given angles is 180°.
Therefore, measure of ∠4 and ∠14 are related in the same way as the measurement of ∠9 and ∠7.
