15. Find the length of x. Round to 1 decimal place.

Answer:

The length of the diagonal is x√10

Step-by-step explanation:

Here, we want to find the length of the diagonal

The diagonal will represent the hypotenuse of a triangle formed with the width and length of the triangle being the measure of the other sides

Mathematically, we then apply Pythagoras’ theorem to get this

we have this as that the square of the diagonal equals the sum of the squares of the two other sides

d^2 = x^2 + (3x)^2

d^2 = x^2 + 9x^2

d^2 = 10x^2

d = √(10x^2)

d = x√10

Answer:

y = -3/2x + 6

Step-by-step explanation:

We won't be able to figure out Y in number form, since we have a second variable, but we can figure it out in terms of X.

First, we have to subtract 6x from both sides

( -4y = -6x + 24 )

Then we have to divide both sides by -4

( y = -3/2x + 6 )

This is our final answer in terms of x

Answer:

1 2/3 aka 1.6666666666666...

Step-by-step explanation:

When you divide 15 by 9 that is the number you get, and you can verify it by then multiplying 9 by 1 2/3 and you get 15. I don't know if they are wanting you so get x, but if they do then you would multiply 6 by the scale factor and you would get 10.

Answer:

The number 200 has two distinct prime factors. The prime factorization of 200 is as follows: 200 = 2 × 2 × 2 × 5 × 5.

Step-by-step explanation:

The index form of 200 as a product of prime factors is 2³ × 5².

The given number is 200.

The index form of a number is that number written as an exponential expression, or a single number raised to another number.

Prime factorization is a process of writing all numbers as a product of primes.

The prime factors of 200=2×2×2×5×5

=2³ × 5²

Therefore, the index form of 200 as a product of prime factors is 2³ × 5².

Answer:

The number of skateboards of each color is 11 and 4

Step-by-step explanation:

Let x represent blue skateboards and

y represent red skateboards.

From the question, the total number of skateboards is 15, that is,

x + y = 15 ...... (1)

and their product is 44, that is,

xy = 44 ...... (2)

From equation (1),

x + y = 15

We can write that

x = 15 - y ...... (3)

Substitute this into equation (2)

xy = 44

(15-y)y = 44

15y -y² = 44

Then,

y² - 15y + 44 = 0

Solve quadratically

y² -4y -11y + 44 = 0

y(y-4) -11(y-4) = 0

(y-11)(y-4) = 0

y-11 = 0 OR y-4 = 0

y = 11 OR y = 4

Put the values of y into equation (3) for x

x = 15 - y

When y = 11

x = 15 - 11

x = 4

and when y = 4

x = 15 -4

x = 11

(4,11) and (11,4)

It is either 4 blue and 11 red skateboards OR 11 blue and 4 red skateboards.

Hence, the number of skateboards of each color is 11 and 4.

Answer: B

Step-by-step explanation:

Let us write down the coordinates of the snow tubing and the ski lift.

Ski Lift = (3 , -4)

Snow Tubing = (3, 3)

We want to find the distance, which can be found by subtracting their y coordinates from each other.

-4 - 3 = 7

or

3 - (-4 ) = 7

If you can, you can always count the squares away each point is from each other. The answer is B - 7 miles.

Answer:

5,720,000 Sq Feet.

Step-by-step explanation:

They are asking the Area of a Trapezoid

Equation =( base + base / 2) x height

Lets first set it up. We know that A-B is 200 feet. & D-C is 260. They are both the bases.

So if you multiply them (200 x 260) You will get 52000.

Now we divide that by 2. (52000 / 2 = 26000)

Now it says the straight line is 220. I think this refers to the height.

Now we multiply 26000 x 220. Which is 5720000.

Its a pretty big number, but that is the answer! :)

Answer:

x = 3.2

Step-by-step explanation:

Since, intercepts made by parallel lines on the transversals are in proportion.

AB = BC.... (given)

[tex] \implies \frac{AB}{BC} = 1..... (2)[/tex]

From equations (1) & (2)

[tex] 1 =\frac{EF}{FG}[/tex]

[tex] {FG}={EF}[/tex]

Answer:

1400

Step-by-step explanation:

There is a flat fee involved, which is the y-intercept of the line.

The line eats the points:

(3, 435)

 and

(5, 625)  

the slope is 190/2 = 95

 B = y - mx = 435 - (95)(3)

                 = 435 - 285

                 =  150

The linear function is:

y = 95x + 150

So for x=2, it will cost

95(2) + 150 = 190 + 150 = 340

435 + 625 + 340 =  1400

The total cost to rent the boat for three days is $1400.

Given that, on Saturday, he rented a pontoon boat for three hours and paid $435.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The cost for the rented a pontoon boat for five hours is 435+190 = 625

The coordinate points are (3, 435) and(5, 625)  

The slope is m = (625-435)/(5-3)

= 190/2 = 95

Now, b = y - mx = 435 - (95)(3)

= 435 - 285 =  150

So, the linear function is y = 95x + 150

So for x=2, it will cost

95(2) + 150 = 190 + 150 = 340

Total cost = 435 + 625 + 340 = 1400

Therefore, the total cost to rent the boat for three days is $1400.

(-1, 0), (3, 0)

The coordinate of the turning point is (1,4) and the coordinates of the roots are (-1,0) and (3,0)

This is the vertex of the equation.

The equation is the given as:

y = 3 + 2x - x^2

According to the graph, the vertex is at the coordinate (1,4)
