Answer:
1. <u>distance</u><u> </u><u>is</u><u> </u><u>2</u><u>1</u><u>0</u><u>k</u><u>m</u>
<u>2</u><u>.</u><u> </u><u>distance</u><u> </u><u>is</u><u> </u><u>1</u><u>6</u><u>3</u><u>•</u><u>3</u><u>k</u><u>m</u>
Step-by-step explanation:
<h2> <u>QN1</u><u>;</u></h2>
<h2> <u>STEP1</u><u>;</u></h2>
SPEED=DISTANCE÷TIME
90km/h= X ÷ 2 hrs and 20mins
<h2> <u>STEP2</u><u>;</u></h2>
CHANGE 20 MINS INTO HRS
1 hr = 60mins
<h2> x</h2>
? = 20mins
<u>2</u><u>0</u><u>m</u><u>i</u><u>n</u><u>s</u><u> </u><u>*</u><u> </u><u>1</u><u>h</u><u>r</u>= 1/3hr
60mins
<h2> <u>STEP3</u><u>;</u></h2>
Speed=distance÷time
90km/h= X ÷ 21/3
Distance= speed * time
X = 90km/h * 21/3hrs
<u>distance</u><u> </u><u>is</u><u> </u><u>2</u><u>1</u><u>0</u><u>k</u><u>m</u>
<h2><u>QN</u><u> </u><u>2</u><u>;</u></h2>
Speed=distance ÷
70km/h= X ÷ 21/3hrs
Distance=speed * time
X = 70km/h * 21/3hrs
Convert what is inside the parenthesis to sixths.
(3/6+2/6-1/6)^3+2/3x4/5
(4/6)^3+2/3x4/5
(2/3)^3+12/15
8/27+12/15
(8x12/27x15)
96/405
32/135
Don't know if that's right though
Square and rectangle
Other example:
To understand the given problem use the formular of area.
Hence, area is the length and width of the object in unit squared.
Mathematically expressing, a = l x w
<span>Since a = l x w </span>
a = lw unit squared
Given:
Area = 112 cm2
Square root of Area = Square root of 112 cm2
Area = 10.58 cm
Check:
Area = (10.58 cm)^2
<span>Area = 111.9 / 112</span>
Step-by-step explanation:
For no. 11
13x + 15 = 19x - 9 ( being opposite sides of parallelogram)
19x - 13x = 15 + 9
6x = 24
x = 4
Also,
4y + 7 ° + 10y - 37° = 180° { being co-interior angles }
14y - 30° = 180°
14y = 210°
y = 210° / 14
y = 15°
For no. 12
5x + 38° = 8x - 19° { being opposite angles of parallelogram }
8x - 5x = 38° + 19°
3x = 57°
x = 19°
Hope it will help :)
