The 90km/h bus runs between the two stations in 2 hours and 20 minutes.
AnnZ [28]

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

I need help please. It’s due tomorrow. I’ve tried three times and gotten the same answer, which my textbook says is wrong
Anna11 [10]

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

2 different shapes with an area of 6 square units and perimeter of 12 units
lisov135 [29]
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>

11.)-If PQRS is a parallelogram, find the values of x and y.
defon

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 :)
