Find the value of x in the given figure

Andrew [12]

Answer:

x = 32

Step-by-step explanation:

(2x + 60) + (3x - 40) = 180 because they are supplementary angles

5x + 20 = 180

5x = 160

x = 32

The region(s) represent the intersection of Set A and Set B (A∩B) is region II

<h3>How to determine which region(s) represent the intersection of Set A and Set B (A∩B)?</h3>

The complete question is added as an attachment

The universal set is given as:

Set U

While the subsets are:

Set A
Set B

The intersection of set A and set B is the region that is common in set A and set B

From the attached figure, we have the region that is common in set A and set B to be region II

This means that

The intersection of set A and set B is the region II

Hence, the region(s) represent the intersection of Set A and Set B (A∩B) is region II

You decide to enter in a rowing competition. To train, you go to the boat house and begin rolling down stream. You row for the s

fredd [130]

Answer:

Time spent rowing down stream $=100\ seconds$

Speed of boat in still water $=14\ ms^{-1}$

Step-by-step explanation:

Let speed of boat in still water be $= x\ ms^{-1}$

Speed of current $= 10\ ms^{-1}$

Speed of boat down stream = $\textrm{Speed of boat in still water +Speed of current}= (x+10)\ ms^{-1}$

Distance rowed down stream = 2400 m

Time spent rowing down stream = $\frac{Distance}{Speed}=\frac{2400}{x+10}\ s$ = $\frac{Distance}{Speed}=\frac{2400}{x+10}\ s$

Speed of boat up stream = $\textrm{Speed of boat in still water -Speed of current}= (x-10)\ ms^{-1}$

Distance rowed up stream = $\frac{1}{6} \textrm{ of distance rowed downstream}=\frac{1}{6}\times 2400 = 400\ m$

Time spent rowing up stream = $\frac{Distance}{Speed}=\frac{400}{x-10}\ s$

We know that,

$\textrm{Time spent rowing down stream =Time spent rowing up stream}$

So,

$\frac{2400}{x+10}=\frac{400}{x-10}$

Cross multiplying

$2400(x-10)=400(x+10)$

Dividing both sides by $400$

$\frac{2400(x-10)}{400}=\frac{400(x+10)}{400}$

$6(x-10)=x+10$

$6x-60=x+10$

Adding 60 to both sides.

$6x-60+60=x+10+60$

$6x=x+70$

Subtracting both sides by $x$

$6x-x=x+70-x$

$5x=70$

Dividing both sides by 5.

$\frac{5x}{5}=\frac{70}{5}$

∴ $x=14$

Speed of boat in still water $=14\ ms^-1$

Time spent rowing down stream = $\frac{2400}{14+10}=\frac{2400}{24}=100\ s$

What is the value of x?

Olegator [25]

Answer:

Step-by-step explanation:

On either side of a line, there is an angle of 180. This means that when two lines intersect, the angles on either side will equal 180.

To solve this problem, add the two angles and set it equal to zero.

(x + 34) + (2x + 2) = 180

x + 34 + 2x + 2 = 180

3x + 36 = 180

3x = 144

x = 48

The value of x is 48.
