Answer:

Step-by-step explanation: Given that eight less than one-third of a number n is -13.

We are to find the value of n.

According to the given information, the equation for n can be written and solved as follows :

Thus, the required value of n is -15. I hope this really helps you(:

Answer:

[tex]\bold{\frac{n}{3} - 8 = - 13}[/tex]

and the solution is
[tex]\bold{n = -15}[/tex]

Step-by-step explanation:

I believe this sentence is mistyped
It should be Eight less than 1/3 a number n is -13

Analyze the word problem piece by piece not necessarily from the beginning of the sentence

Step-by-step explanation:

The correct answer is option A

Answer:

:/

Step-by-step explanation:

Answer:

x = 3, y = 1

Step-by-step explanation:

Given the 2 equations

2x + y = 7 → (1)

3x - 4y = 5 → (2)

Multiplying (1) by 4 and adding to (2) will eliminate the y- term

8x + 4y = 28 → (3)

Add (2) and (3) term by term to eliminate y

11x = 33 ( divide both sides by 11 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (1)

2(3) + y = 7

6 + y = 7 ( subtract 6 from both sides )

y = 1

solution is x = 3 and y = 1

Answer:

It will take him 1 hour 35 minutes to finish a 10 mile race

Answer is (C)

Cody runs 10-mile in 1 hour 35 minutes.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

Cody runs 4 miles in 38 minutes.

Now,

Since, Cody runs 4 miles in 38 minutes.

Hence, The time to run 10 miles = 38 × 10 / 4

                                                  = 380/4

                                                  = 95 minutes

                                                  = 1 hour 35 minutes

Thus, Cody runs 10-mile in 1 hour 35 minutes.

Answer:

p= 18,275

Step-by-step explanation:

The function would be p=29,175(-0.925)^t. You would then substitute t for 6 and solve from there to get p=18,275.

Answer:

Each of the domain values, x, should only output a single unique range value, y.

This example is a relation and not a function because the the domain value of -1 output 2 distinct range values.

-1 outputs a 3

and

-1 outputs a 5

If I were to draw a vertical line at the domain value of -1 that vertical line would intersect the points (-1,3) and (-1,5). Which indicates that the relation

Step-by-step explanation:

the answer is 48

The area of the window is [tex]\frac{25x}{2} -(1 +\frac{\pi}{2} )\frac{x^2}{2}[/tex]

The shape of the Norman window is described as a rectangle surmounted by a semicircle.

Let 'x' be the width of the window.

Then this width corresponds to the diameter of the semicircle.

That is, radius of the semicircle = x/2

Now given the perimeter of the whole window = 25 ft

This perimeter is equal to the sum of 3 sides of the rectangle and the perimeter of the semicircle.

Perimeter of the semicircle = [tex]\frac{2\pi r}{2} = \frac{\pi x}{2}[/tex] , where r is the radius of the semicircle.

Now let 'y' be the length of the window.

Then sum of three sides of the window = 2y + x

So 2y + x + [tex]\frac{\pi x}{2}[/tex] = 25

Therefore, [tex]y =( 25 - x - \frac{\pi x}{2} ) / 2[/tex]

Area of the window = Area of the semicircle + Area of the rectangle =

 [tex]\frac{\pi x^2}{8} +xy = \frac{\pi x^2}{8} + x( 25 - x - \frac{\pi x}{2} ) / 2\\ = \frac{\pi x^2}{8} + (25x - x^2 - \frac{\pi x^2}{2} ) / 2[/tex]

 So Area of the window = [tex]\frac{25x}{2} -(1 +\frac{\pi}{2} )\frac{x^2}{2}[/tex]

Explanation:

Of your original given list, let's write down the parallelograms. They are:

So we cross those off the list since we want a quadrilateral with no sides parallel. A parallelogram, by definition, is a quadrilateral with both pairs of opposite sides that are parallel.

We can also rule out the trapezoids because a trapezoid is a four sided figure (quadrilateral) where we have exactly 1 pair of parallel sides, while the other sides are not parallel.

Lastly, we can rule out the kite because any kite has perpendicular diagonals.

The only thing left is quadrilateral. In my opinion this answer should be more specific and say "quadrilateral that isn't a parallelogram, a trapezoid, or a kite", but I think I see what your teacher was going for here.
