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.

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:

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:

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

So the right answer is 8 1/8 ft^2.

look at the attached picture

Hope it will help you..

Good luck on your assignment..

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

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:

254

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

Answer:

y = 2x + 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

6x - 3y = 15 ( subtract 6x from both sides )

- 3y = - 6x + 15 ( divide all terms by - 3 )

y = 2x - 5 ← in slope- intercept form

with slope m = 2

Parallel lines have equal slopes, thus

y = 2x + c ← is the partial equation

To find c substitute (- 2, 4) into the partial equation

4 = - 4 + c ⇒ c = 4 + 4 = 8

y = 2x + 8 ← equation of parallel line

The required equation of the parallel line is,

[tex]6x-3y+24=0[/tex]

Equation of parallel lines:

Parallel lines are lines that never intersect. Because of this, a pair of parallel lines have to have the same slope, but different intercepts (if they had the same intercepts, they would be identical lines).

Given, the equation of the line is [tex]6x-3y=15[/tex]

Let the equation of the parallel line be,

[tex]6x+3y+k=0[/tex]...(1)

Since, the equation (1) passes through the point (-2,4) then,

[tex]6(-2)-3(4)+k=0\\-12-12+k=0\\k=24[/tex]

Now, substituting [tex]k=24[/tex]  in equation (1) we get,

[tex]6x-3y+24=0[/tex]

Answer:

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

   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
