construct a 45-45-90 degree triangle with leg equal to AB

Answers

Lines AB and BC form a 90 degree angle. The other two angles, lines AC and BC and lines AC and AB from 45 degree angles.

The required 45-45-90 degree triangle is shown, where each of the two acute angles is 45 degrees and the length of the hypotenuse is equal to the length of each leg multiplied by the square root of 2.

What is the right-angle triangle?

A right-angled triangle, also known as a right triangle, is a triangle in which one of its interior angles measures exactly 90 degrees. The side opposite the right angle is called the hypotenuse, and the other two sides are called the legs.

Here,
o construct a 45-45-90 degree triangle with leg AB, we can follow these steps:

Draw a line segment AB and mark its midpoint as point M.Using a compass, draw a circle centered at point M with a radius AB. This circle will intersect AB at points C and D, which are equidistant from point M.Draw a line segment CD to connect points C and D. This line segment is the hypotenuse of the 45-45-90 degree triangle we want to construct.Draw a perpendicular bisector to AB at point M. This will intersect CD at point E, which is the midpoint of CD.Draw a line segment AE, which is one of the legs of the 45-45-90 degree triangle.Draw a line segment BE, which is the other leg of the 45-45-90 degree triangle.Label the triangle ABC with angle measures of 45 degrees at angles A and B, and 90 degrees at angle C.

The resulting triangle will have sides AB, BC, and AC, where AB and BC are equal in length and AC is the hypotenuse.

Jack's family left home at 9:00 AM and drove to the amusement park at 60 mph. They spent 7 hours at the park and then drove back home. On the way home, traffic was bad and they drove 20 mph slower than in the morning. They got home at 8:00 PM. How far is the amusement park from Jack's home?

Answers

Answer:

96

Step-by-step

the distance from the amusement to jack's home is x (mile, x>0)

jack's family went to the amusement park at: 9 + x/60

On the way home, traffic was bad and they drove 20 mph slower than in the morning⇒ they drove: 60 - 20 = 40 mph

they left the amusement park at: 20 - x/40

have the following equation:

(20 - x/40) - (9+ x/60) = 7

⇔ 4 = x/40 + x/60

⇔ x = 96

so the distance from the amusement park to jack's home is 96 mile

                                         

Distance of amusement park from Jack's home = 96 miles

Let the distance from Jackie's house to the amusement park be x.

She drove at a speed of 60 mph to get to the amusement park.

Now, formula for time is;

Time = distance/speed

Time; t1 = x/60 hours

Now, we are told she spent 7 hours at the park. Thus; t2 = 7 hours

On her way back home from school, we are told she drove 20 mph slower than her speed in the morning. Thus, speed = 60 - 20 = 40 mph

Thus; time; t3 = x/40

Now, she left home by 9 am and got home by 8pm same day. This is a total of t = 11 hours

Thus;

t1 + t2 + t3 = 11

Plugging in the relevant values;

(x/60) + 7 + (x/40) = 11

Rearrange to get;

(x/60) + (x/40) = 11 - 7

(x/60) + (x/40) = 4

Multiply through by 120 to get

2x + 3x = 480

5x = 480

x = 480/5

x = 96 miles

The event coordinator asks you to determine how many students participated in the track-and-field day. The total number of students in seventh and eighth grade combined is 584; "5" /"8" of them are seventh graders and "3" /"8" of them are eighth graders. If "4" /"5" of the seventh graders participated in track-and-field day and "7" /"8" of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer.

Answers

Given that, the total number of students in seventh and eighth grade combined is 584.

The number of students in seventh grade= 5/8 of the total number of students.

[tex]=\frac 5 8 \times 584=365[/tex]

As 4/5 of the total seventh-grade students participated in the track-and-field-event.

So, the number of seventh-grade students participated

[tex]= \frac 4 5 \times 365=292[/tex]

The number of students in the eighth grade 3/8 of the total number of students.

[tex]=\frac 3 8 \times 584=219[/tex]

As 7/8 of the total eighth-grade students participated in the track-and-field-event.

So, the number of seventh-grade students participated

[tex]= \frac78 \times 219=191.625.[/tex]

The number of students must be a counting number, but here, as per the given information, the number of seventh-grade students participated coming out a fractional number, so the given information is incorrect.

Although, as per the given data, the mathematical value of the total number of students participated from both the grade combined

=292+191.625

=483.625 (mathematically)

Again, in real life, the fractional value of the total number of students is not possible.

Given that, the total number of students in seventh and eighth grade combined is 584.

What is the solution to the following system of equations?
X - 3y = 5
2x + y = 10
(5,0)
(0,5)
(7,0)
(0,7)

Answers

Option 1 is the correct answer

(5,0)

Answer:

( 5, 0 )

Step-by-step explanation:

 x - 3y = 5

2x +  y = 10  multiply by 3 to eliminate y and solve for x

 x - 3y = 5

6x + 3y = 30  then add

7x          = 35

simplify:

x = 35 / 7

x = 5  

substitute x = 5 back into the eq.2

 2x +  y = 10

2(5) +  y = 10

           y = 10 - 10

           y = 0

therefore the answer is ( 5, 0 )

A purse contains a collection of quarters, dimes, nickels, and pennies. The average value of the coins in the purse is 17 cents. If a penny is removed from the purse, the average value of the coins becomes 18 cents. How many nickels are in the purse?

Answers

Answer:

There are total of 17 coins in the purse

Step-by-step explanation:

Let x represent the no of coins in the purse

Let y represent the total amount

 y/x = 0.17

y = 0.17*x............................(i)

y-0.01 / x-1 = 0.18

y - 0.01 = 0.18x -0.18........(ii)

We substitute y = 0.17 x into the second equation:

0.17x - 0.01 = 0.18x - 0.18

0.17 = 0.01x

x = 17

Hence, there are total of 17 coins in the purse
