Answer:

The run is 4.875 miles long, while, the bike is 6.875 miles long.

Step-by-step explanation:

Let d = running distance and d' = biking distance.

Given that d' = d + 2 and v = running speed = 6 mph and v' = biking speed = 10 mph.

Since time, t = distance/speed, running time, t = running distance/running speed = d/6 and biking time, t' = biking distance/biking time = d'/10 = (d + 2)/10.

Since the total time, t" = 90 minutes = 1.5 hours,

t + t' = t"

So, d/6 + (d + 2)/10 = 1.5

multiplying through by the L.C.M, 30, we have

30 × d/6 + 30 ×(d + 2)/10 = 30 × 1.5

5d + 3(d + 2) = 45

expanding the brackets, we have

5d + 3d + 6 = 45

collecting like terms, we have

8d = 45 - 6

8d = 39

d = 39/8

d = 4.875 miles

d' = d + 2 = 4.875 + 2 = 6.875 miles

So, the run is 4.875 miles long, while, the bike is 6.875 miles long.

AQ = 8

QD = 4

========================================================

Explanation:

A median goes from a vertex to the midpoint of the opposite side. The medians of this triangle are segments AD, BE, and CF.

The three medians intersect at the centroid. The centroid cuts the median AD such that

Note how 2/3+1/3 = 3/3 = 1

Since AD = 12, we know that

As a check,

AQ+QD = 8+4 = 12 = AD

So AQ+QD = AD is a true equation.

Answer:

√43/8 can not be a rational number. Because the numerator of the fraction is not an integer.

Therefore, option C i.e. irrational is correct.

Step-by-step explanation:

What is a rational number?

We know that a rational is a number that can be expressed in the form of a fraction p/q of two integers p and q.

Where

Given the number

√43/8

here

So,

√43/8 can not be a rational number. Because the numerator of the fraction is not an integer.

Therefore, option C i.e. irrational is correct.

As given,   3.2x+0.2^2-5=0  we have to find value of x

3.2x+0.04-5=0

3.2x-4.96=0

3.2x=4.96

x=4.96/3.2

x=1.55 Ans....

Answer:

[tex]x = 2 \: or \: \frac{ - 1}{6} [/tex]

Step-by-step explanation:

Lets open the brackets.

[tex]6 {x}^{2} - 12x + x - 2 = 0[/tex]

Now lets factorise it.

[tex] = > 6 {x}^{2} - 12x + x - 2 = 0[/tex]

[tex] = > 6x(x - 2) + 1(x - 2) = 0[/tex]

[tex] = > (x - 2)(6x + 1) = 0[/tex]

Here x will have two values.

1) [tex]x - 2 = 0[/tex]

[tex] = > x = 2[/tex]

2) [tex]6x + 1 = 0[/tex]

[tex] = > 6x = - 1[/tex]

[tex] = > x = \frac{ - 1}{6} [/tex]

Answer:

x = 40

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

So first you would do 12+8=20

Then you would do 20÷0.5=40

Now you want to check your answer

0.5x40=20 and 20-8=12

So x=40

Answer:

Angles vertically opposite to each other are equal.

Step-by-step explanation:

There are two lines AB and CD intersecting at point O making angles 1 ,2,3 and 4.

The angles 1 and3  , angles 2 and 4 are vertically opposite angles.

Now consider the line AB

<1 + <2= 180 degrees--------- eq A

Now consider the line CD

<2+ <3= 180 degrees-----------eq B

As both equations are equal

< 1+ <2= <2+ <3 = 180 degrees

or

< 1+ <2= <2+ <3     or

< 1=  <3                           subtracting <2 from both sides

Now consider the line BA

<3+ <4= 180 degrees--------- eq C

Now consider the line DC

<4+ <1= 180 degrees-----------eq D

As both equations are equal

< 3+ <4= <4+ <1 = 180 degrees

or

< 3+ <4= <4+ <1    

or

< 3=  <1                           subtracting <4 from both sides

This holds true for all vertically opposite angles that they are equal.

These can be measured with a protractor.

This can also be proved that if we add angles 1,2,3 and 4 we will get 360

and if we subtract  angles 1 & 2 from 360 we will get 180 degrees which angles 3&4 make together.

<1+<2+<3+<4= 360 degrees

But <1 +<2= 180  

360 - [ <1+<2] = 180 degrees

<3 +<4= 180  

<1 +<2= <3 +<4= 180
