David drove a distance (d) of 187km, to 3 significant figures. He used 28 litres of petrol (p), to 2 significant figures.
The petrol consumption (c) in km per litre is given by the formula: c= d/p
By considering bounds, work out the value of c, to a suitable degree of accuracy. You must show your working and give a reason for your answer. I'm not totally comfortable with sig figs, but I believe that the answer can only be expressed as accurately as least number of sig figs of any data used in the computations.....thus ....the answer should be rounded to 2 sig figs
So
187 / 28 = 6.67 ⇒ 6.7 km / L [rounded to 2 sig figs ].
Ur x axis will be the number of cans and ur y axis will be the weight in oz
u will label ur x axis( the number of cans) in intervals of 1......from 0 to 4
u will label ur y axis (the weight) in intervals of 10....from 0 to 40
ur equation would be : y = 10x
points on this line are : (0,0), (1,10), (2,20), (3,30), (4,40)
Answer:
<h2><em><u>
960 people </u></em></h2>
Step-by-step explanation:
If each side of the basketball arena is 20 ft. X 30 ft, the area of each side of the basketball arena = 20ft * 30ft = 600ft².
Since all the four sides are filled with people, the total area of the 4 sides will be expressed as 4*600 = 2400ft²
If each person takes up 2.5ft², total number of people in the arena will be gotten by simply dividing the area of all the four sides by the area took up by each person.
Total number of people in the arena = area of all the four sides by the area/ area took up by each person.
Total number of people in the arena = 2400/2.5
Total number of people in the arena = 960 people.
<em><u></u></em>
<em><u>Hence there are approximately 960 people in the arena.</u></em>
Answer: 
Step-by-step explanation:
The equation is 
.
To find the value of the variable "x" in terms of "y", you need to apply the Division property of equality and divide both sides of the equation by "2a". Then:
You know that the costants "a" and "b" are equal (
), then:
Knowingt this, you can simplify.
Therefore, you get that the value of "x" in terms of "y" is:
Answer:
<h3><em>
315 red flowers</em></h3><h3><em>
420 white flowers</em></h3><h3><em>
315 yellow flowers</em></h3>
Step-by-step explanation:
1050 flowers
3/10 of them are red=> 3/10 *1050=3*105=315 red flowers
2/5, (or 4/10), are white =>4/10 * 1050=4*105=420 white flowers
=> 1050-(315+420)=1050-735=315 yellow flowers
