Math and Science connections-The fastest lava flow measured was 60km/hr a horse outrun this flow at 48mi/hr?shown all work?
Answers
Answer 1
Answer:
5 miles = 8 km to 1 d.p. 60 x 5/8 = 37.5 miles (Lava Flow) 37.5 < 48 (Horse) In addition, that was only the fastest speed that it was recorded. This means that there would have been slower rates of movement, further decreasing the flows total distance in an hour.
Which expression is equal to a x a x a x b x bA- a²b³ B-a³b² C- 3a x 2b D- 3a² x 2b²
Answers
B,because 3 a's and 2 b's so that's a 3 times and b 2 times
Which expression has a value of 36 when x=4 and y=7 A. 2xy B. 2x+4y C. 6y-x D. 12x-2y
Answers
so subsitute x=4y=7 A. 2xy=2 times 4 times 7=2 times 28=56 not 36 B. 2x+4y=2 times 4+4 times 7=8+28=36 true
the answer is B
the answer is b, because 2x4 is 8, 4x7 is 28 and 8+28+36
X - b = a what is answer and show work plz!
Answers
x-b=a x+b=a +b ---------- X= a/b All you need to do is get the x alone
If 16 counters are 4/9 then what is One
Answers
36...
divide your 16 by 4, so that you have 1/9. You then multiply the resulting number(4) by your denominator, 9. 4 times 9 = 36
What is the equation of the graphed line? Hint: Determine the slope of the line y = x.
Answers
y=-5x
you can use point slope or slope intercept to find this one. i did it by using slope intercept, y=mx+b b in this case is 0, and then to find m you use (y-y)/(x-x) or (-5-0)/(1-0) = -5
