Answer:
67.3km/h
Step-by-step explanation:
Find the amount of time it took from 10:12 to 11:18.
Which is 66 minutes.
Find the average speed.
Formula of average speed =
Total distance/time
Which is,
74/66 = 1.121 (recurring decimal)
1.121 x 60 = 67.26km/h
= 67.3km/h (Estimated to 1 dp)
Answer:
41,6 cm
Step-by-step explanation:
Formula for Perimeter of a rhombus: P = 2L + 2H (H is the height, L the length)
Perimeter: 160 cm = 2L + 2(38,4 cm), or
160 cm + 76.8 cm + 2L, or
83.2 cm = 2L
and so the height (altezza) is H = 83.2 cm / 2 = 41,6 cm
Answer:
<h3>B. The number of people who attended the mathematics conference was more than 225.</h3>
Step-by-step explanation:
Given the inequality m > 225, the inequality means that m is greater than 225. Since the inequality sign does not include equal to sign, then the value of m cannot be less than and equal to 225. The situation that best fits the expression based on the explanation above is "The number of people who attended the mathematics conference was more than 225"
Emphasis should be on 'WAS MORE THAN' according to the statement. The greater sign means that the number of people will always be greater than or more than 225 representing the variable <em>m as the number of people.</em>
