Answer: The answer is the third figure. Attached the image.
Step-by-step explanation: Given that Zahra runs a 500-meter race at a constant speed. We are to select the correct graph from the four options that will show her distance from the finish line during the race.
We can see in graph 2, the distance covered by Zahra in metres increases at the same rate as the time increases in minutes.
But, since we are considering from the finish line, so option (#) will be right, because Zahra starts at 500 metres, decreases in the same manner as the increase of time and goes down to 0 on the positive X-axis.
Also,
Thus, the attached graph, which is the third option is the correct graph.
Answer:
The area should be 170
Step-by-step explanation:
L× W =70×10=170
Answer:
your are very loser but me, is very inteligent but you nono
Step-by-step explanation:
9/8 because you multiply 3 × 3 and leave the denominator the same
L = 2 W
B = L x W = 2 W²
Side Area = 2 W H + 2 L H = 2 H ( W + L ) = 6 H W
V = 2 W² H = 10
H = 5 / W²
Cost = 15 * 2 W² + 9 * 5/W
= 30 W² + 270/ W
C ` = 60 W - 270 / W²
= ( 60 W² - 270 ) / W² = 0
60 W² = 270
W ² = 270 : 60
W² = 4.5
W = √ 4.5 = 2.12
Cost (min) = 15 * 2 * 4.5 + 30 / 2.12 = 135 + 14.15 = $149.15
Answer: The cost of materials for the cheapest such container is $149.15.
