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:
Axioms are generally statements made about real numbers. ... Sometimes they are called algebraic postulates. Often what they say about real numbers holds true for geometric figures, and since real numbers are an important part of geometry when it comes to measuring figures, axioms are very useful
Answer:
4/45
Step-by-step explanation:
First find all the pairs that make 9 that are two digit:
1+8
2+7
3+6
4+5
5+4
3+6
2+7
1+8
That's 8 pairs, and as there are 90 two digit numbers, 8/90 is the answer. but if you want to simplify, the answer is 4/45
To get for the taxi accidents in 1998, we must note that x =
8. Therefore using the equation y=−143.3x2+1823.3x+6820 , we can
calculate for the number of taxi accidents.
y = -143.3 * (8)^2 + 1823.3 * 8 + 6820
y = 12,235.2
There were about 12,235 taxi accidents in 1998.
Answer:
4.
D.
4. 5x + 64.95
Step-by-step explanation:
Simply distribute the 5
5(x + 12.95)
5x + 5(12.95)
multiply 12.95 by 5
64.75
so
5x+64.75
