Gerard concluded that the triangle with sides √95 feet, 8 feet, and √150 cannot be used as a building frame support on the house because it is not a right triangle. How did Gerard come to that conclusion? Explain.

Answers

Answer 1

Answer:

Sample Response: Gerard determined that the squares of the two smaller sides did not equal the square of the longest side. The side lengths did not create a true statement of the Pythagorean theorem.

Answer 2

Gerard most likely came to the conclusion that the sides of the triangle do not conform to the Pythagorean Theorem.

What is the Pythagorean Theorem?The Pythagorean Theorem states that the sum of the squares of the two smaller legs of a right triangle equals the square of the longer side.Thus, if a and b are the length of the two smaller sides of a right triangle, and c is the longest side, then: a² + b² = c².

Therefore, Gerard most likely came to the conclusion that the sides of the triangle do not conform to the Pythagorean Theorem.

A bicyclist covered 5/7 of his route and an additional 40 miles. He has yet to cover 118 miles less than 0.75 of his route. How long is his route in miles?

Answers

Answer:

168 miles.

Step-by-step explanation:

5/7x+40+0.75x−118=x

Step 1: Simplify both sides of the equation.

5/7x+40+0.75x−118=x

5/7x+40+0.75x+−118=x

(5/7x+0.75x)+(40+−118)=x(Combine Like Terms)

1.464286x+−78=x

1.464286x−78=x

Step 2: Subtract x from both sides.

1.464286x−78−x=x−x

0.464286x−78=0

Step 3: Add 78 to both sides.

0.464286x−78+78=0+78

0.464286x=78

Step 4: Divide both sides by 0.464286.

0.464286x/0.464286=78/0.464286

x=168

Final answer:

The total length of the bicyclist's route is 560 miles. This is solved by setting up an equation based on the given information and solving for the total route length.

Explanation:

To solve this problem, we first need to represent the problem using equations by setting X as the total route. We know that the bicyclist has already covered 5/7 of his route and an additional 40 miles. So, the part of his route he has already covered is expressed as [tex](5/7)X + 40.[/tex]

We also know that he has yet to cover 118 miles less than 0.75 of his route, so the part of the route that he has yet to cover is expressed as 0.75X - 118. Since the parts of the route already covered and yet to be covered add up to be his entire route (X), we can set up the equation as follows: ([tex](5/7)X + 40 = 0.75X - 118[/tex]. By solving this equation, we find that X (the total length of his route) equals 560 miles.

Find the measure of a central angle of a regular polygon with 10 sides

Answers

Answer:

114 degrees

Step-by-step explanation:

The formula to find the measure of all angles in a regular polygon is [tex](n-2)180[/tex], where n = total number of sides.

Thus, we substitute n for 10, and you get:

[tex](10-2)180=1440[/tex]

If the shape is a regular polygon and it has ten sides, meaning all sides are equal, then all you do is divide 1440 by 10, to get the final answer of 114.

A central angle in a regular ten-sided polygon would be 144 degrees.

Final answer:

The central angle of a regular polygon with 10 sides (a decagon) is calculated by dividing 360° by the number of sides, resulting in a central angle of 36°.

Explanation:

To find the measure of a central angle of a regular polygon with 10 sides (a decagon), we use the formula for the measure of each central angle:

Central Angle = 360° / Number of sides

Thus, the central angle of a regular decagon is:

360° / 10 = 36°

This is because the central angles are equally distributed around the center point, dividing the 360° of a circle evenly by the number of sides in the polygon.

A preschool playground has both bicycles and tricycles. There is a total of 30 seats and 70 wheels. how many bicycles are there? how many tricycles are there? ​

Answers

Answer:

20 bicycles and 10 tricycles.

Step-by-step explanation:

Let the number of bicycles and tricycles be x and y respectively.

Each vehicle has 1 seat.  Each bicycle 2 wheels and each tricycle 3 wheels.

Then we have the system of equations:

x + y = 30 ............ (1)

2x + 3y = 70.........(2)

Multiply the first equation by -2:

-2x - 2y = -60......(3)

y = 10

Substituting for y in equation (1):

x + 10 = 30

x = 20.    

By simultaneous equation, there are a total of 20 bicycles and 10 tricycles.

Six is subtracted from a number the result is divided by four this result is added to 10 to give 30 what is the number

Answers

let's say the number is X and the result is YX-6=Yy/4+10=30y=(30-10)x4=80so X=80+6=86

Answer: The number is 86.

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:

"Six subtracted from a number ", a number means the variable (x), and six subtracted from a number is "x -6".

"The result is divided by 4", so (x-6) /4.

This result is added to then, so: 10+ (x-6) /4.

And finally, to give 30 means that all the expression equals to 30.

10+ (x-6) /4 = 30

Solving:

(X-6) /4 = 30 -10

(X-6) /4 = 20

X-6 = 20x4

X-6 = 80

x =80+6

x= 86

The number is 86.

3. What is the value of X in the triangle? Round only you’re final answer to the nearest hundredth.

Answers

Answer:

1. X = 23.8 cm

2. Z = 12.5 Inches

3. x = 14.03 Degrees

Step-by-step explanation:

1. Given

Hypotenuse=25 cm  

Angle=18 Degrees

We will use the trigonometric ratios for right angled triangles for finding the value of X.

In the given triangle, as X is the base, we will use the ration which involves base and hypotenuse.

So,

cos⁡θ=  Base/Hypotenuse

cos⁡18=X/25

0.9510=X/25

0.9510*25=X

X=23.775

X=23.8 cm

2.The ratio of cos will be used for this one too.

Here,

Base=10 inches

Angle=37 Degrees

cos⁡θ=  Base/Hypotenuse

cos⁡37=10/Z

0.7986=10/Z

Z=10/0.7986

Z=12.521  

Z=12.5 inches

3. As we know the values of perpendicular and base ,  

So the ration which involves these both will be used.

The desired ratio is  

tan⁡ x=Perpendicular/Base

tan ⁡x=5/20

tan⁡ x=0.25

x =  tan^(-1)⁡0.25

x = 14.03 Degrees  ..

Final answer:

The value of X and Z in a triangle should be determined by performing mathematical operations and rounding according to the specific rules of significant figures for addition, subtraction, multiplication, and division, following proper rounding at the final calculation to ensure precision.

Explanation:

To answer the question regarding the value of X and Z in a triangle, it's important to note that the rounding of numbers should be done according to certain rules based on the operations involved.

In addition and subtraction, the result should have the same number of decimal places as the measurement with the least number of decimal places. For instance, adding 135.621, 97.33, and 21.2163 we get 254.1673, which is then rounded to 254.17 since the hundredth's place is the last common decimal place.

With multiplication and division, the answer should have the same number of significant figures as the original measurement with the least significant figures. Thus, multiplying 1.35 by 2.1 we get 2.835 and round it off to 2.8.

When dealing with whole numbers or in a series of steps, pay close attention to significant figures and round off only after the final calculation to prevent inaccuracies.

As an example, the complex calculation (13.2 + 12.252) x (1.35 x 2.1) should be rounded only once, after the entire expression is evaluated, leading to a result of 72.

The product of two whole numbers is 180 and their sum is36. What are the two numbers?

Answers

Answer:

6,30

Step-by-step explanation:

The product of two whole numbers is 180

xy = 180

and their sum is 36

x+y = 36

x = 36-y

Substitute this into the first equation

(36-y) (y) = 180

36y - y^2 = 180

Add y^2 to each side

36y = 180 +y^2

Subtract 36y from each side

0 = y^2 -36y +180

Factor

0=(y-6) (y-30)

Using the zero product property

y-6 =0   y-30 =0

y = 6    y= 30

Now we need to find x

If y =6

x = 36-6=30

If y = 30

x = 36-30=6

The two numbers are 30 and 6
