Answer:
If a^2 + b^2 =c^2, then the triangle is a right triangle.
Step-by-step explanation:
Given
Shape: Triangle
Sides: a, b, c
Longest: c
Required
Select the true statements (See comment section for options)
From the options, we can see that we need to prove if the triangle is right-angled or not.
Since side c is the longest side, it means that side c is the hypotenuse.
Applying Pythagoras theorem
We have that:
[tex]a^2 + b^2 = c^2[/tex]
If the above mathematical statement is true, then the triangle is right-angled
Answer:
If a^2 + b^2 =c^2, then the triangle is a right triangle.

Stephanie and Jose both want to buy a skateboard. Stephanie has already saved $25 and plans to save $5 a week until she can buy the skateboard. Jose has $16 and plans to save $8 a week. How many weeks will it take for them to have the same amount of money and how much will they have?
(Also if u can pls type out ur answer like "10 weeks and $100" hehe)
Answer: 3 weeks and $40
Step-by-step explanation:
Let the number or weeks taken for them to have same amount be represented by x.
The information given in the question can be presented as an equation as:
Stephanie = 25 + 5x
Jose = 16 + 8x
We then equate them together
25 + 5x = 16 + 8x
25 - 16 = 8x - 5x
3x = 9
x = 9/3 = 3
The number of weeks is 3
The amount of money that they'll have will be:
= 25 + 5x
= 25 + 5(3)
= 25 + 15 = $40

Juan thinks that the graph of 6y + 12x = 4 is a line. a. Solve Juan’s equation for y.
The equation of the line in the slope-intercept form will be y = 2/3 - 2x.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Juan thinks that the graph of 6y + 12x = 4 is a line.
Solve the equation of the line for y, then we have
6y + 12x = 4
6y = 4 - 12x
y = 4/6 - (12/6)x
y = 2/3 - 2x
The equation of the line in the slope-intercept form will be y = 2/3 - 2x.

Find the value of x in the diagram. Explain how you found the answer.
Answer:
x = 65
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 given angles from 180° for third angle
third angle = 180° - (60 + 55)° = 180° - 115° = 65°
65° and x are vertical angles and are congruent, thus
x = 65
Answer:
x = 65 degrees
Step-by-step explanation:
Three angles are marked with their values: 55 and 60 degrees. Thus, the third interior angle of the left triangle (unmarked) is 180 degrees - (115) degrees = 65 degrees.
This 65 degree angle and x are vertical angles. Thus, x = 65 degrees. This plus y form a straight angle, so y = 180 degrees - 65 degrees = 115 degrees.
Suppose that the height H of a Ferris wheel can be modeled by the function n H(t)= -16cos(t/45)+24, where t is the time in seconds. What is the maximum height of a cabin? Use 3.14 for π
Answer:
40 feet.
Step-by-step explanation:
The height of the Ferris Wheel is modeled by:
[tex]\displaystyle H(t)=-16\cos\Big(\frac{t}{45}\Big)+24[/tex]
Where H(t) is the height (in feet (assuming)) and t is the time in seconds.
Remember that the value of cosine, regardless of the input, will always be between -1 and 1. That is:
[tex]-1\leq \cos(t)\leq 1[/tex]
So, we can use the two maximums. Testing -1 and 1, we get:
[tex]H(t)=-16(1)+24=8[/tex]
And:
[tex]H(t)=-16(-1)+24=40[/tex]
Therefore, the maximum height of a cabin of the Ferris Wheel will be 40 feet in the air.
Notes:
And the minimum height will be 8 feet.
We are not asked to find t. To do so, however, set H(t) = 40 and find the general solution for t.

What is the simplified expression of (2x -8) + (3x-2)
Answer:
5x-10
Step-by-step explanation:
Answer:
5x-10
Step-by-step explanation:
You can add the x together, 2+3 is 5 so we have 5x.
The you add the other numbers, -8+-2 is -10.
You then can put the addition in, and have 5x+-10. Since 10 is a negative, there's no need to put the addition sign, so 5x-10 would be the answer.

On a Saturday, Saul can cut 4 lawns in 6 hours. If Mitch can mow lawns at the same rate, how long will it take him to mow 9 lawns?
12 hours
12 3/4 hours
6 hours
13 1/2 hours
Answer:
13 1/2 is your answer.
Step-by-step explanation:
With the same ratio the time taken Mitch to mow 9 lawns will be 13 + 1/2 thus option (D) is correct.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
Saul can cut 4 lawns in 6 hours.
The ratio of hours to lawns will be as,
6/4
Suppose the time taken to mow 9 lawns to Mitch is x hours.
The ratio of hours to lawns will be as
x/9
Since the rate is the same thus ratio must be the same.
x/9 = 6/4
x = 6/4 x 9
x = 13.5 = 13 + 1/2
Hence"With the same ratio, the time taken Mitch to mow 9 lawns will be 13 + 1/2".

Tony has $300 in his bank account. He takes out $10 each week for "W" weeks. After "W" weeks he has "D" dollars left in his bank account. Write an equation that represents the amount of money left in his bank account after "W" weeks.
Answer:
The Equation :
D = 300 - 10W
Step-by-step explanation:
We are told in the above question that:
Tony has $300 in his bank account. He takes out $10 each week for "W" weeks.
Where W = number of weeks
Our Equation is written as
Total amount in the bank account - $10 × W
= $300 - $10 × W
The Equation is given as
D = 300 - 10W
The area of this trapezoid is what?
Answer:
The area of this trapezoid is 8cm
Answer:
130
Step-by-step explanation:
first decompose the trapezoid into a square in the middle and 2 triangles on the left/right side, both triangles are congruent so you only find the area of one triangle, which is 9 because do 2x9 = 18/2 = 9, now let's move on to the middle square 14 x 18 = 112, then you add them all up remember there are 2 triangles,
112 + 9 + 9 = 130

-2y+6=-12
What does y equal?
Answer:
y = 9
Step-by-step explanation:
-2y+6=-12
subtract 6 on both sides: -2y=-18
divide both sides by -2: y=9
Answer:
[tex]y = 9[/tex]
Step-by-step explanation:
1) Subtract 6 from both sides.
[tex] - 2y = - 12 - 6[/tex]
2) Simplify -12-6 to -18.
[tex] - 2y = - 18[/tex]
3) Divide both sides by -2.
[tex]y = \frac{ - 18}{ - 2} [/tex]

Kira ,Charlie , and Miguel have a total of $105 in their wallets . Kira has $9 less than Miguel. Charlie has 4 times what Miguel has . How much does each have ?
Let the money with Miguel be x.
Then :
Money with Kira = x - 9
Money with Charlie = 4x
Total money in their wallet = $105
This can be written in an equation as :
[tex] = \tt \: x + x - 9 + 4x = 105[/tex]
[tex] = \tt2x + 4x - 9 = 105[/tex]
[tex] = \tt 6x - 9 = 105[/tex]

[tex] = \tt6x = 114[/tex]
[tex] = \tt x = \frac{114}{6} [/tex]
[tex] = \tt x = 19[/tex]
Which means :
Money with Miguel = $19
Money with Kira :
