 Let x be the number of miles he travelled on the  first day
Then on the second day he travelled  x / 1.5 miles
so we have the equation

x + x/1.5 = 1380

multiply through by 1.5:-
1.5x + x = 2070
2.5x = 2070
x = 2070 / 2.5 = 828 miles answer

Its C

Solve for x,y, and z.
Ann [662]

The given triangle is isosceles, so the two remaining angles in the triangle both have measure <em>xº</em>. The interior angles of any triangle sum to 180º, so that

58º + <em>xº</em> + <em>xº</em> = 180º

58 + 2<em>x</em> = 180

2<em>x</em> = 122

<em>x</em> = 61

Angles <em>y</em> and <em>z</em> are supplementary to angle <em>x</em>, so that

<em>xº</em> + <em>yº</em> = 180º

and

<em>xº</em> + <em>zº</em> = 180º

and consequently, <em>y</em> = <em>z</em>. In particular, we get

<em>y</em> = 180 - 61

<em>y</em> = 119

and so

<em>z</em> = 119

The linear scale factor of two shapes is 3:4. If the area of the smallest shape is 72^2 what is the area of the big shape?​
Lorico [155]

Answer:

\boxed{6912 units^2}

Step-by-step explanation:

<em>Hey there!</em>

Well using the given ratio,

3:4

And the area of the small shape we need to do,

72*72 = 5184

Now we can make the following fractions,

\frac{3}{4} = \frac{5184}{x}

Now we can solve,

3*x = 3x

4 * 5184 = 20736

3x = 20736

20736 / 3

x = 6912

So the area of the bigger shape is 6912 units^2

<em>Hope this helps :)</em>

ZanzabumX [31]

Answer:

23:44 or 1:1.91

Step-by-step explanation:

w:l =69:132     Divide each number by   3

     = 23:44     Divide each number by 23

     ≈   1:1.91

The width-to-length ratio is 23:44 or approximately 1:1.91
