Answer:
72km
Step-by-step explanation:
alex : tomos : annabelle = 2 : 3 : 4
if tomos drove 24km
tomos ratio is 3
so 3 --> 24
<em>1 --> 8 </em>
<u>total ratios --> 2 + 3 + 4 = 9</u>
so total journey is 9 --> 9 * 8 = 72km

a)Represented by a different letter in the figure above.
b)Positioned in the figure above so that A*B*C,B*G*E,and D*E*F are equal.
Which digit does G represent?
G represents the digit 2
Answer:
x > -22/7
Step-by-step explanation:
Given inequality:
- 7x - 15 < 6
<em>adding 15 to both sides:</em>
==> -7x - 15 + 15 < 6 + 16
==> -7x < 22
<em>dividing</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>7</em><em>:</em>
==> -x < 22/ 7
<em>multiplying</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>-</em><em>1</em>
<em>(</em><em>anytime</em><em> </em><em>you</em><em> </em><em>multiply</em><em> </em><em>the</em><em> </em><em>inequality</em><em> </em><em>by</em><em> </em><em>-</em><em>1</em><em> </em><em>you</em><em> </em><em>must</em><em> </em><em>flip</em><em> </em><em>th</em><em>e inequality sign–</em><em> </em><em>r</em><em>e</em><em>p</em><em>l</em><em>a</em><em>c</em><em>e</em><em> </em><em>the</em><em> </em><em>"</em><em><</em><em>"</em><em> </em><em>with</em><em> </em><em>"</em><em>></em><em>"</em><em>)</em>
==> <u>x > -22/7</u>
Step-by-step explanation:
it clearly consists of 2 rectangles and 1 triangle (as you tried correctly to point out by drawing the separating lines).
we only need to calculate all 3 areas and add them up for the total.
the area of a rectangle is
length × width
so, in our 2 cases we have
6 × 2 = 12 km²
5 × (3 + 2 + 3) = 5×8 = 40 km²
the area of a triangle is
baseline × height / 2
in case of a right-angled triangle the 2 sides enclosing the 90° angle can be used as baseline and height.
so, in our case
6 × (5 + 2 + (3 + 2 + 3 - 2)) / 2 = 6×(7 + 6)/2 = 3×13 = 39 km²
in total, the whole area is
12 + 40 + 39 = 91 km²
