Answer: 20 : 3 : 12
Step-by-step explanation:
For every 1 litre, 150 ml of sucrose and 600ml of saline solution is needed.
1litre = 1,000 ml
Water = 1,000 ml
Ratio:
1,000 : 150 : 600
Divide by 50 to get simplest form:
20 : 3 : 12
You would write +19 to indicate an increase of 19
The opposite of that would be -19, read out as negative 19.
1. For multiplication and division), we first compare the number of significant figure (let's call it SF later in the problem) that the factors have. The product will have the least numbers between them. So, for the case of 11.55 x 2.5, 11.55 has 4 SF while 2.5 has 2. So we choose the smallest which is 2 for this case. Hence, the answer is B.
2. Using the same rules as mentioned in Item 1, we first compare the number of SF in the numbers give. 975.0321 has 7 SF while 0.0003 has 1 (all zeroes not following a counting number are not significant). We now solve for the quotient and round it off to 1 SF.
(975.0321/0.0003) = 3250107. Rounding it off, we have 3000000 or 3 x 10⁶. Thus, the answer is D.
3. The rules for multiplication still apply even for more than two factors. So, let's first take note of the SF present in each factor as shown below.
0.00147 = 3 SF
8.314 = 4 SF
7.100 = 4 SF (zeroes after a counting number in the decimal place are considered significant)
From this, we can see that the product must round off to 3 SF. Multiplying the three numbers, we have
0.00147 x 8.314 x 7.100 = 0.086773218
So, the product rounded off to 3 SF is 0.0868 or 8.68 x 10⁻². So, the answer must be C<span>.

In order to make this easier, let us convert the fraction into a mixed number. 2 2/3 would become 8/3. Now, let us divide 8 pints by 8/3 cups and we get 24/8 or 3 cups. Therefore, the amount of water that Cary has to use when she makes barbecue sauce with 1 pint of tomato is 3 cups.
Answer:
Step-by-step explanation:
If carla wants to spend the least amount of money she should go to the Braves game because it has one of the lowwest admission and the food is cheaper than any where else. Yes, the concert admission is the same price but the tee-shirts and soda costs more.
