The triangle with sides 40m, 50m, 60m is not a right angled triangle .
What is Pythagoras' theorem?Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
Pythagoras' theorem :
[tex]Hypotenuses ^{2} = Perpendicular^{2} + Base^{2}[/tex]
According to the question
Sides of triangle are 40m, 50m, 60m
As hypotenuses is the largest side
Applying Pythagoras' theorem
[tex]Hypotenuses ^{2} = Perpendicular^{2} + Base^{2}[/tex]
[tex]60 ^{2} = 40^{2} + 50^{2}[/tex]
3600 ≠ 1600 + 2500
3600 ≠ 4100
Hence, The triangle with sides 40m, 50m, 60m is not a right angled triangle ,

why must the vertex of an isosceles triangle be an even number
Answer:
Step-by-step explanation:
The vertex of an isosceles triangle must be an even number because its identical base angles are congruent. Therefore if the angle at the vertex is x, then the vertex of an isosceles triangle must be an even number because its identical base angles are congruent. Therefore if the angle at the vertex is x, then the .

Answer:
[tex]\lim_{x \to 2^+} f(x)=0[/tex]
Option C is correct option.
Step-by-step explanation:
We are given:
[tex]f(x)=\begin{cases} x^3 , x<2 , \ then \ \lim_{x \to 2^+} f(x)= \\ x-2, x>2\\\end{cases}\\[/tex]
Since the limit given is x-> 2⁺ so, values greater than 2 will be considered. So, we will consider f(x)=x-2 x>2
Putting x=2
f(x)=x-2
f(2)=2-2
f(2)=0
So, [tex]\lim_{x \to 2^+} f(x)=0[/tex]
Option C is correct option.

The Chambers family has driven 603 miles at a constant speed of 67mph. How many hours have they been driving. Use d = rt to solve.
Write an equation for the situation that will represent the distance for any time.
Answer:
d = 67t
and
eqn d = 67t represents d over time.
Step-by-step explanation:
part one : find the hours they have been driving
d = 603 miles driven
r = 67 mph
t = ?
r = d/t
rt = d
t = d/r
t = 603/67
t = 9
unit = in hours
they have been driving for 9 hours.
part 2 : find an equation for the situation that represents distance for any time
t is the independent variable
d will represent the dependent variable
let r represent the slope
d = rt
d = 67t
therefore the eqn d = 67t represents d over time.

We can use the points in either order and you will still get the same slope. I usually solve in order that is given. So the first coordinates I label (x1,y1) and the second is (x2,y2).
Slope=m=(y2-y1)/(x2-x1)

Last month the ending balance on Maryanne’s Mastercard was $1,789, the average daily balance was $755, and the monthly periodic rate is 1.85%. Her finance charge can be calculated by multiplying the ending balance times the monthly periodic rate. So the finance charge is $1,789 ´ 0.0185 = $33.10.
Answer:
False
Step-by-step explanation:
Based on the information given we can calculate the finance charge of Maryanne’s by simply multiplying her average daily balance which is the amount of $755 times her monthly periodic rate which is 0.0185.
Hence, Maryanne's finance charge is calculated by using this formula
Finance charge=Average daily balance*Monthly periodic rate
Let plug in the formula
Finance charge= $755* 0.0185
Finance charge= $13.97
Therefore Maryanne's finance charge will be $13.97

The area of abcd
is 10cm^2 show that x^2 +6x =1
Answers
Maths
GCSE

The area of square ABCD is 10 cm^2 . Show that x^2 + 6x = 1 (requires diagram which I will draw on the whiteboard).
The area of a square is the length of one side squared (multiplied by itself), so for a square with side length 3, the area will be 32 or 3 x 3, which = 9. For a square with side length x, the area will be x2 .Given that the length of one side is 3 + x, the area will be (3+x)2 This can be written as (3+x) * (3+x), and to expand these brackets we will use the 'crab claw' method. We will take the first value in the first bracket, and times it by both values of the second bracket. So we will multiply 3 by 3 which is 9, and then 3 by x which is 3x. We will then take the second value in the first bracket and multiply is by both values in the second bracket. So we will multiply x by 3 which is 3x, and then x by x, which is x2. Now we will add together all the the values we have just found: x2 + 3x + 3x + 9. Because the only like terms are 3x and 3x, and 3x + 3x = 6x, the final equation we form after expanding the brackets will be x2 + 6x + 9.. Given that the area of the square is given as 10cm2, 10 must be equivalent to x2 + 6x + 9, so we form the equation x2 + 6x + 9 = 10. When balancing equations, you must do whatever you do on one side to the other side. Therefore if we take 9 away from the left hand side, we must take 9 away from the right hand side (10 - 9 = 1), leaving us with x2 + 6x = 1, and completing the question.

find the area and perimeter
Answer: P=3 A=7 I think.
Step-by-step explanation:
The perimeter is basically how many sides are there so on this shape there is 3 if u count it and the area is how many squares or whatever is inside the shape so the 11 and 23 stand for the squares on those sides where the numbers are so if u add 11+23=34 so on the last side it only shows u 1 square and has no number so now u have to make the rest of those square till u cant and on the end of it it cant be a square bc its a triangle so it does not have a square like type of shape to where u can make it even. I hope this helps have a nice day or night:)
