The total temperature of the magnesium sample is its original temperature plus the temperature increase which is dependent on time. This total should exceed 650 degrees. Thus, the inequality that best describes the condition is,
255 + 10m ≥ 650
m ≥ 39.5
The answer is letter b.
Answer: 1,38
Step-by-step explanation: Because 48,345 ÷ 34,886 = 1,385799461101875, so I rounded off to 1,38
78 could be seventy-eight, 78 over 1, and 78/1.
Answer:
75 × 12 + 30m = 990
∴ m = 3
Step-by-step explanation:
Assume the number of months Talia brings a guest to be 'm'.
So the amount of Talia has to pay for guests for one year is $ 30m .
So, <em>total amount of money Talia has pay for one year = (monthly membership cost)×(number of months in a year) + (additional amount for guests)</em>
Total cost = $990
Monthly membership cost = $75
Number of months in a year = 12
Additional amount for guests = $ 30m
∴ The equation which gives you the number of moths she brought guests is:
990 = 75×12 + 30m
990 = 900 + 30m
990-900 = 30m
30m = 90
∴ m = 3
Answer:
length of an arc = 1unit
Step-by-step explanation:
given that the circumference of a circle = 6
central angle = 60
length of the arc =?
recall that the circumference of a circle = 2πr
6 = 2πr
r = 6/2π
now to calculate the length of an arc
recall,
length of an arc = 2πr(Ф/360)
length of an arc = 2π(6/2π) × 60/360
length of an arc = 6 × 60/360
length of an arc = 360/360
length of an arc = 1unit
therefore the length of the arc whose circumference is 6 and arc angle is 60° is evaluated to be 1unit
