Answer:
78
Step-by-step explanation:
40 x 76 is the equation by 4x4 of 86 and the 36
77 unicorns, because yesterday the ratio was 6:5 and today it is 3:4. If you add the numbers for both ratios together, you get 11 and 7. Finding the LCM of these two gives 77 (because 7 and 11 are both prime).
You find the LCM of the sums because when you find values based on ratios, you divide value by the sum of the ratio.
e.g. I have 100 fruits. The ratio of apples to oranges is 2:3. How many apples are there?
To solve this you'd add 2 and 3 (5), divide 100 by 5 (20), multiply that by 2 (40) because that's the ratio of apples to oranges.
In this case, you do the reverse. So If I have 77 unicorns, then yesterday there were (77/11 = 7, 7*6= 42, 7*5= 35) 42 green unicorns and 35 yellow. The sum of 42 and 35 is 77. If you do this process with the other ratio you'll get similar results as well.
Answer:
+7 or 7
Step-by-step explanation:
an integer is a whole number. So the question asks what whole number represent this real world situation. A positive charge to an atom can not be represent by a negative number (number below zero). Therefore, it has to be positive.
Hope this helps, the y intercept is 3 ans the x intercepts are +1.3 and -1.3
C. 42.39 times 0.1 is 4.239. 42.39-4.239= 38.151 which rounds to 38.15
