45 seconds. Since there are 60 seconds in a minute and 60/4 is 15. 15*3 is 45. Hope this helped!
Answer:
24 miles
Step-by-step explanation:
2.5 inches represents 15 miles,
so 1 inch must represent 15/2.5 = 6 miles.
Since the cities are 4 inches apart on map, they will be 6*4 = 24 miles apart in actual.
Answer: 81.2
Step-by-step explanation:
h(t) = -5t² + 40t + 1.2
h(4) = -5(4)² + 40(4) + 1.2 We plug 4 seconds as t, and solve h(4)
h(4) = -80 + 160 + 1.2
h(4) = 80 + 1.2
h(4) = 81.2
Answer:
c = F-32; 68-32 = 36°C.
Step-by-step explanation:
the real conversation equation is f = 9/5 C + 32. but for the sake of this problem we are ignoring the coefficient.
so it's 36°C
X=18 (3/8)
(8x/7) +9 = 30
subtract 9 from both sides
8x/7=21
multiply 7 from both sides
8x=147
divide 8 from both sides and you get
x=18 (3/8)
