Using proportions, it is found that the average speed of the motorcycle is of 64 km/h.

A proportion is a fraction of a total amount.

In this problem, in one and one-quarter hours, that is, [tex]\frac{1} + \frac{1}{4} = 1.25[/tex] hours, the car traveled 20 km farther, hence the number of km/h by which the car is faster is given by:

f = 20/1.25 = 16 km/h.

The car's velocity was of 80 km/h, hence the average speed of the motorcycle is given by:

m = 80 km/h - 16 km/h = 64 km/h.

Answer:

31 cylinders

Step-by-step explanation:

Hello!

Let's first find how much water is held by the cylinder. To find this, we must find the volume (amount of space it takes up) of the cylinder

[tex]V = \pi r^ * h\\\\V = \pi (6/2)^2*8\\\\V = \pi* 3^2*8\\\\V = \pi* 9*8\\\\V = 72\pi[/tex]

Now let's find the volume of the rectangular prism.

[tex]V = 24*24*12\\\\\\V = 6912[/tex]

Now, let's divide the Volume of the fish tank by the cylinder:

[tex]6912 / 72\pi\\\\\\\text{Approx } 30.58\\ = \text{Approx 31 cylinders}[/tex]

Because we can't use half full cylinder, we round up to the nearest whole number: 31

Answer:

31 cylinder containers are needed to completely fill the fish tank.

Step-by-step explanation:

The stuffs required to solve this question:

Where r is radius, h is height, l is length and b is breadth. So, now just use these formulae and solve the question.

A cylinder container is given whose height is 8 inches and diameter is 6 inches. We are aware about the fact that radius is half of diameter. So, the radius of the cylindrical container is 3 inches.

Volume of cylindrical container = π × (3)² × (8)

Volume = 72π or 226 (approx.)

Similarly, a rectangular prism is provided whose length, breadth and height is 24, 24 and 12 inches respectively.

Volume of rectangular prism = 24 × 24 × 12

Volume = 6912

'n' is the number of cylindrical containers required to fill the fish tank. So,

→ n = Volume of rectangular prism/Volume of cylindrical container

→ n = 6912/226 = 30.58

→ n = 31 (approx.)

Answer:

5mph

Step-by-step explanation:

Let speed of boat in still water is s.

Distance proportional to speed

90/10 = (s+ 4)/(s - 4)

=> 9s - 36 = s + 4

=> 8s = 40

=> s= 5 mph

Factorization is writing the expression in terms of multiplication of its factors. The given expression is prime(option A), thus, no factors.

Those polynomials with integer coefficients that cannot be factored further, with factors of lower degree and integer coefficients are called prime polynomial.

(it is necessary that no factors exists having their coefficients are still integers and they're of lower degree)

Suppose the given quadratic equation is

[tex]ax^2 + bx + c = 0[/tex]

Then its solutions are given as

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

Finding the roots of [tex]3x^2 - x + 5 =0[/tex], we get:

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} = \dfrac{1 \pm \sqrt{(-1)^2 - 4\times 5 \times 3}}{2 \times 3} = \dfrac{1 \pm \sqrt{1-60}}{6}[/tex]

Its square root is not real(if not using complex numbers, then its solution doesn't exist, making the roots non-real, and thus, polynomial not being able to get factorized. )

Can you provide an image of the bar chart?

Ok so you need to look at the coordinate points of the shape and it'll be like this (x,y). 5 units left means you need to subtract 5 from all the x values and 1 unit up means you need to add 1 unit to all the y values. Once you do that, you'll have a new set of coordinate points that you need to graph.

Answer:

-4

Step-by-step explanation:

1st Step:

Set up our equation, so we get x + 69 + 25 + 90 = 180

Remember: All sides of a triangle add to 180.

2nd Step:

Now that we've got our equation: x + 184 = 180. Subtracting 184 from 180 gives us -4, which is our answer.

Key Points To Remember:

- The angles of a triangle always add up to 180.

- The little square at the bottom of the triangle means the angle is 90.

y=x+5

Step-by-step explanation:

y-y1=m(x-x1) POINT-SLOPE FORM

Plug in your point and slope

y-3=1(x+2)   (The signs flip because of the negative)

y-3=x+2 (SIMPLIFY)

y=x+5  (Move the three. It is now slope int form)

You can check by plugging in -2 for x, and get 3 for y. (it works)

Answer: C

Step-by-step explanation:

For the parallelogram to be a square, all sides must have equal measure and all angles must be right.

This means that CD=AD -> 20=8x-4 -> 24=8x -> x=3

And 4y-3=45 -> 4y=48 -> y=12

Step-by-step explanation:

for mean w. you have to add up all the values (cat weights) and divide them by the number of cats

and for median w. you need to compare the values from the smallest to the largest and cross out the numbers from the ends. Since there are 6 cats here (odd number) you will have 2 values left. Add them up and divide them by 2 (since there are 2)

The factor of the provided polynomial after the factorization process are similar to option B, which is

[tex](x+4)(3x+1)(3x-1)[/tex]

The factor of a polynomial is the terms in linear or equation form, which are when multiplied together, give the original polynomial equation as result.

Find these factors by taking out the common factors.

The given polynomial equation in the problem is,

[tex]9x^3 +36x^2 - x - 4[/tex]

The above equation has the unknown variable x and the highest power of this unknown variable is 3.

Take out the highest common factor 9x², which can divide each term of the first two terms of equation (9x³, 36x²). Thus,

[tex]9x^2(x +4) - x - 4[/tex]

Take out the highest common factor -1 from the second two terms as,

[tex]9x^2(x +4) -1( x + 4)[/tex]

Now take out the common group (x+4) as,

[tex](x +4) ( 9x^2 -1)[/tex]

The second group can be rewritten using the difference of square formula as,

[tex](x +4) ( (3x)^2 -1^2)\\(x+4)(3x+1)(3x-1)[/tex]

Thus, the factor of the provided polynomial after the factorization process are similar to option B, which is

[tex](x+4)(3x+1)(3x-1)[/tex]
