So for an isosceles right triangle with side length

Similarly, if the hypotenuse of an isosceles right triangle has length of

The height (one of the legs) and the hypotenuse of an isosceles right triangle are 40 feet and 40√2 feet, respectively.
What is Pythagoras theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
The triangle is an isosceles right triangle.
That means, the triangle has two equal sides.
Let, base b = height h.
The area of the triangle = 1/2 x base x height.
800 = (1/2)b²
b² = 1600
b = 40 feet.
Now, using the Pythagoras theorem,
Hypotenuse = √(1600 + 1600)
Hypotenuse = √(3200)
Hypotenuse = 40√2 feet.
Therefore, height = 40 feet and hypotenuse = 40√2 feet.

The breadth of the rectangular firls is 20m less than its length.. Find its dimensions if perimeter is 160 m
Answer: length of the rectangular firls = 50
and the breadth = x-20m= 50-20m =30m
Step-by-step explanation:
The perimeter of a rectangle is given as 2(l+b)
let the length be represented as x
such that the breadth = x-20m
so our expression for the perimeter of the rectangular firls becomes
Perimeter = 2l+ 2b
160= 2x + 2 ( x-20)
160= 2x+ 2x-40
160+40 =4x
200= 4x
x= 200/4
x= 50
So the length of the rectangular firls = 50
and the breadth = x-20m= 50-20m =30m
Answer:
Length =60m
Breadth= 20m
Step-by-step explanation:
Breadth of the rectangular firls = 20m
Perimeter = 160m
Length = X
Perimeter of a rectangle = 2(L +B)
Where L= Length
B = Breadth
160 = 2( 20 + X)
160 = 40 +20X
160- 40 =20X
120= 20X
20X = 120
X = 120/20
X = 60
The dimensions are:
Length =60m
Breadth= 20m

Lionel has at most 63/8 cups of flour to bake cookies and a cake. Lionel uses 7/4 cups of flour to make the cake. If each batch of cookies takes 3/2 cups of flour, how many batches of cookies, x, can Lionel bake? Select the inequality that includes the maximum number of batches of cookies Lionel can bake.
A. x⊇49/8
B. 49/8⊆x
C. 49/12⊆x
D. x⊇49/12
Answer:
x ≤ 49 / 12
Step-by-step explanation:
Total cups of flour = 63 /8
Cake = 7/4 cups
Cookies = 3/2 cups per batch
Flour left after baking cake :
63/8 - 7/4
(63 - 14) / 8
49 / 8
Batch of cookies which can be baked, x
Flour left / cups of flour per batch of cookies
x ≤(49 / 8) ÷ (3 / 2)
x ≤ (49 /8) * 2/3
x ≤ 98 / 24
x ≤ 49 / 12

What is the price ofpremium gasoline rounded to the nearestdollar? Rounded to the nearest dime?Rounded to the nearest penny?
Answer:
$4 (nearest dollar) ;
$4.4 (nearest dime) ;
$4.41 (nearest penny
Step-by-step explanation:
The actual price of premium gasoline is $4.409 per gallon.
A penny = $0.01 or 1 cent
A dime = $0.1 or 10 cent
Price of premium gasoline to the nearest dollar :
$4.409 is rounded to the nearest unit = $4
Price of premium gasoline to the nearest penny : = $4.409 is rounded to the nearest hundredth = $4.41
Price of premium gasoline to the nearest dime : = $4.409 is rounded to the nearest tenth = $4.4

What is the slope of the line shown below?
Answer:
2/3
Use the rise over run formula and then simplify
Answer:
D
Step-by-step explanation:
Slop formula: m = (y2 - y1)/(x2 - x1)
First coordinate: (-3, -7)
Second coordinate: (9, 1)
m = (1- (-7) ) / (9 - (-3) )
m = (1 + 7) / (9 + 3)
m = (8)/(12)
m = 2/3

Find the lengths of the segments with variable expressions.
Answer:
EF = 8
Step-by-step explanation:
The midsegment EF is half the sum of the parallel bases , that is
x = [tex]\frac{x-5+2x-3}{2}[/tex] ( multiply both sides by 2 to clear the fraction )
2x = 3x - 8 ( subtract 2x from both sides )
0 = x - 8 ( add 8 to both sides )
8 = x
Thus
EF = x = 8
AD = x - 5 = 8 - 5 = 3
BC = 2x - 3 = 2(8) - 3 = 16 - 3 = 13
