in right angle traingle two angle are equal

so.x=y

in triangle

x+y+90=180(sum of interior angle of triangle)

2x=180-90

x=90/3=45°

Answer:

7 hours and 30 minutes

Step-by-step explanation:

[tex]240 \div 4 = 60km \: per \: h[/tex]

[tex]450 \div 60 = 7.5 = 7h \: 30min[/tex]

It will take motor bike 7.5 hours to cover 450 Km of distance.

Speed of a body is defined as the distance travelled by it per unit time taken to cover the distance.

Mathematically-

S = Δd/Δt  or   S = {d(2) - d(1)}/{t(2) - t(1)}

It is a scalar quantity as it only has magnitude and no direction.

Given is a motor bike travels 240 km ins 4 hours.

We can calculate the speed of the bike as -

s = 240/4 = 60 Km/hr

Then, the time taken to cover 450 Km will be -

t = 450/60

t = 7.5 hours

Therefore, it will take motor bike 7.5 hours to cover 450 Km of distance.

The graph of the system in the attached figure

Step-by-step explanation:

we have

isolate the variable y

----> equation A

This is the equation of a vertical parabola open down (because the leading coefficient is negative)

The vertex represent a maximum

the vertex is the point (0,2)

---> equation B

This is the equation of a circle centered  at (0,0) with radius 3 units

The solution of the system of equations is the intersection points both graphs

Answer:

12

Step-by-step explanation:

12 is a two digit #

Answer:

first of all there are many ways to compare numbers. example

I don't know how to compare them but I try my best

Step-by-step explanation:

the first 3 numbers have only one digit but the 4th has 2 digits.but it in my opinion you don't want this answer.

so this is not the reason

3 have 2 factor

6 have 4 factor

9 have 3 factor

12 have 5 factors

so as the number increase the factors should increase but 9 has less factors than 6 .so I think 9 is the different one

Answer:

2 1/3

Step-by-step explanation:

1 3/4  is equivalent to 7/4

1 1/3 is equivalent to 4/3

7/ 4 x 4/3

reduce with greatest common factor so the two 4 are out (show a line crossing out the top and bottom 4 )

now you're left with 7 x 1/3 = 7/3

7/3 = 2 1/3

The product of two given mixed fractions is [tex]2\frac{1}{3}[/tex].

The given mixed fractions are [tex]1\frac{3}{4}[/tex] and [tex]1\frac{1}{3}[/tex].

The product of two fractions is the product of the numerators and the product of the denominators.

Product of two fractions = Product of their denominators / Product of their numerators.

Here, the mixed fraction [tex]1\frac{3}{4}[/tex] can be written as [tex]\frac{7}{4}[/tex] and the mixed fraction [tex]1\frac{1}{3}[/tex] can be written as [tex]\frac{4}{3}[/tex].

Now, 7/4 × 4/3

= 7/3

= [tex]2\frac{1}{3}[/tex]

Therefore, the product of two given mixed fractions is [tex]2\frac{1}{3}[/tex].
