The length of the hypotenuse of a [tex]45^{\circ}-45^{\circ}-90^{\circ}[/tex] triangle with a leg length of 50 centimeters is [tex]50\sqrt{2}[/tex].

The formula to calculate the hypotenuse of [tex]45^{\circ}-45^{\circ}-90^{\circ}[/tex]  traingle is to multiply the length of the leg by [tex]\sqrt{2}[/tex].

The length of the two legs of [tex]45^{\circ}-45^{\circ}-90^{\circ}[/tex] triangle is equal.

Then the length of its hypotenuse will be calculated by multipling the length of the leg and [tex]\sqrt{2}[/tex].

Since the length of the leg is 50 centimeters,

Then its hypotenuse will be

[tex]h=50\times\sqrt{2}\\h=50\sqrt{2}[/tex]

So, the length of the hypotenuse will be [tex]50\sqrt{2}[/tex].

Answer: A,B,D,E

Step-by-step explanation: All of them either have a base and height of 4, or if its E, it is 8 by2. The formula for solving a triangle is base x height divided by 2. In this case, the two sides have to equal 16, as the area is 16/2, or 8

the triangles that have an area of 8 square units in the picture are

A, B, D  and E

Given :

The graph of 4 triangles are given

We know that the area of the triangle formula is

[tex]\frac{1}{2} \cdot base \cdot height \\[/tex]

Lets find out the area of each triangle .

(A) base =4  and height =4

[tex]Area=\frac{1}{2}\cdot 4 \cdot 4=8 \; square \; units[/tex]

(B) base =4, height =4

[tex]Area=\frac{1}{2}\cdot 4 \cdot 4=8 \; square \; units[/tex]

(C) base = 3 and height =5

[tex]Area=\frac{1}{2}\cdot 5 \cdot 3=\frac{15}{2} \; square \; units[/tex]

(D) base =4  and height =4

[tex]Area=\frac{1}{2}\cdot 4 \cdot 4=8 \; square \; units[/tex]

(E) base = 8 and height =2

Answer:

Θ = 0, π, [tex]\frac{7\pi }{6}[/tex], [tex]\frac{11\pi }{6}[/tex]

Step-by-step explanation:

Using the identity

cos2Θ = 1 - 2sin²Θ, then

sinΘ + 1 = 1 - 2sin²Θ ( subtract 1 - 2sin²Θ from both sides )

2sin²Θ + sinΘ = 0 ← factor out sinΘ from each term

sinΘ(2sinΘ + 1) = 0

Equate each factor to zero and solve for Θ

sinΘ = 0, hence

Θ = [tex]sin^{-1}[/tex] (0) = 0, π, 2π

2sinΘ + 1 = 0 → sinΘ = - [tex]\frac{1}{2}[/tex] , thus

Θ = [tex]sin^{-1}[/tex] ( - [tex]\frac{1}{2}[/tex] ) = - [tex]\frac{\pi }{6}[/tex]

Since sinΘ < 0 then Θ is in third/ fourth quadrants, thus

Θ = π + [tex]\frac{\pi }{6}[/tex] = [tex]\frac{7\pi }{6}[/tex] or Θ = 2π - [tex]\frac{\pi }{6}[/tex] = [tex]\frac{11\pi }{6}[/tex]

Solution is

Θ = 0, π, [tex]\frac{7\pi }{6}[/tex], [tex]\frac{11\pi }{6}[/tex] for 0 ≤ Θ < 2π

Answer:

[tex]f(x)=89x+1800[/tex]

Step-by-step explanation:

$1800 is spent on a washing machine. This number never changes, so we just need to add that to our annual total

$89 is spent every year. This means that this number needs to be with our variable, x, as it is dependent on the number of years that occur. When we put these two things together, we get the following equation:

[tex]f(x)=89x+1800[/tex]

Answer:

Joey sold 6 cars

Step-by-step explanation:

Joey earns $350 per week + $200 per car he sells

The number of cars that he sold last week is unknown, so represent it with a variable, x.

Write an equation

$350 + $200x = $1,550

Subtract $350 from both sides of this equation

$200x = $1200

Divide both sides of the equation by 200

x = 6

let p be the percentage

then

2 = 8 × p%

Answer:

2*sqrt2

Step-by-step explanation:

In right isosceles triangles, the ratios of the sides are:

1:1:sqrt(2)

1=the legs, and sqrt2 being the hypotenuse.

So, in this problem, we can simply divide the hypotenuse by sqrt2 to find the legs.

2*sqrt6/sqrt2=2*sqrt3

Therefore, the lengths of the legs are 2*sqrt2

Answer: B

Step-by-step explanation:

The answer is B, because if he practices 49 times out of 100, then you know that it is a fraction of 49/100.

49/100 can also be changed into a decimal, making it 0.49.

Answer:

A: 61/100 or 0.61%

Step-by-step explanation:

He practices 49/100 days, but the question is asking us what percentage of days, he does not practice. He practices 49% of the days, but does not practice 100-49/100 days=61/100 days.

Answer:

8 1/8 ft^2

Step-by-step explanation:

The area of a rectangle is found by

A = l*w

A = 3 1/4 * 2 1/2

Change to improper fractions

3 1/4 = (4*3+1)/4 = 13/4

2 1/2 = (2*2+1)/2 = 5/2

A = 13/4 * 5/2 = 65/8

Changing back to a mixed number

8 goes into 65 8 times (8*8=64) with 1 left over

65/8 = 8 1/8 ft^2

Step-by-step explanation:

I did the test on edenuity and got it right

The surface area of a rectangular prism with length = 7 inches, width = 9 inches and height = 4 inches is 254 inches square.

Surface area of a rectangular prism = 2(lw + lh + wh)

where

Therefore,

length = 7 inches

width = 9 inches

height = 4 inches

Therefore,

surface area  = 2(63 + 28 + 36)

surface area  = 2(127)

surface area  = 254 inches²

The slope is 1

Step-by-step explanation:

Pick two points

(-1,0) and (0,1)

The slope is given by

m= (y2-y1)/(x2-x1)

   = (1-0)/( 0 - -1)

   = (1-0)/(0+1)

   = 1/1

Hello there!

Y = mx + b

Looking at the graph we can find our y-intercept, which would be 0,1.

To find the slope, we can use any two coordinates on the line, such as

(-1,0) and (0,1).

Plug it into the slope formula: rise over run.

1 - 0 / 0 - - 1 = 1/1

1/1 = 1

Therefore our slope is 1x.

Lastly, we just plug the values in for our slope intercept form.

y = 1x + 1
