Marcus can drive his boat 36 miles down the river in 3 hours but takes 4 hours to return upstream. Find the rate of the boat
in still water and the rate of the current.

Answers

Answer:

With river 12 miles per hour

Against river 9 miles per hour

wv = water velocity vsw = boat velocity in still water

vsw +wv = 12 mph

vsw -wv = 9 mph

2 * vsw = 21 mph

boat velocity in still water = 10.5

Since vsw + wv = 12 then

water velocity = 1.5 mph

Step-by-step explanation:

Answers

Answer:

9) y = -3x - 4

10) y = -1/3x + 14/3

11) y = x - 1

12) y = -7/5x - 18/5

13) y = 3/5x + 9/5

14) y = -2x - 3

Step-by-step explanation:

For this explanation, let's use the last problem as the example. You would use the formula y=mx+b. The first thing you would need to find would be the slope, or m. So, you would find the slope and conclude the answer is -2. After that, you would solve for b and get the answer. Hope this helped!

3x-2y=1x+4y=33 elimination process

Answers

Answer:

x = 5 ; y = 7

Step-by-step explanation:

3x - 2y = 1 --------------------(I)

x + 4y = 33 ------------(II)

Multiply equation (II) by (-3) and then add. So, x will be eliminated and we can find the value of y

(I) 3x - 2y = 1

(II)*(-3) -3x -12y = -99 {Now add}

- 14y = -98

y = -98/14

y = 7

Plugin y = 7 in equation (I)

3x - 2*7 = 1

3x - 14 = 1

3x = 1 + 14

3x = 15

x = 15/3

x = 5

EB Is parallel to DC , so

Angle AEB = Angle ADE

( because they are corresponding angle pair )

Angle ABE = Angle ACD

( because they are corresponding angle pair )

triangle ADC Is similar to triangle AEB

(By AA similarity criteria )

hence AE / ED = AB / BC ( by CPCT )

so 24/10 = 12/x

A rectangular mat has an area of 7/12 in2. The length of the mat is 5/6 in. What is the width of the mat

Answers

The width of the mat with the given area and length is 7/10 in.

What is the width of the mat?

The area of a rectangle is expressed as;

A = l × w

Where l is length and w is width.

Given the data in the question;

Area A = 7/12 in²Length l = 5/6 inWidth w = ?

We plug our given values into the above equation and solve for w.

A = l × w

7/12 = 5/6 × w

w = 7/12 ÷ 5/6

w = 7/12 ÷ 6/5

w = 42/60

w = 7/10 in

Therefore, the width of the mat with the given area and length is 7/10 in.

The graph y = 1/2x^2 - x - 4 is shown below. State the coordinate of the zero(s):

Answers

Answer:

Zeros → (-2, 0) and (4, 0)

Step-by-step explanation:

Equation of the graph has been given as,

y = [tex]\frac{1}{2}x^{2} -x-4[/tex]

For zeros of the function,

y = 0

Therefore, [tex]\frac{1}{2}x^{2} -x-4=0[/tex]

By solving the equation algebraically,

x² - 2x - 8 = 0

x² - 4x + 2x - 8 = 0

x(x - 4) + 2(x - 4) = 0

(x + 2)(x - 4) = 0

x = -2, 4

Therefore, coordinates of the zeros will be (-2, 0) and (4, 0).

Let's confirm the zeros (x-intercepts) from the graph attached,

Coordinates of the x-intercepts are,

(-2, 0) and (4, 0)

The average citizen must be a good citizen if our republics are to succeed. The stream will notpermanently rise higher than the main source; and the main source of national power and national greatness is found in the average citizenshipof the nation.

There are many men who feel a kind of twister pride in cynicism, there are many who confine themselves to criticism of the way others dowhat they themselves dare not even attempt. There is no more unhealthy being, no man less worthy of respect, than he who either really holds,or feigns to hold, an attitude of sneering disbelief toward all that is great and lofty, whether in achievement or in that noble effort which, even ifit fails, comes to second achievement.
