Answer:
-9
Step-by-step explanation:
Just plug in
4(-3) - 3(3) - 12(-1)
= -12 - 9 + 12
= -9
Can you take a picture of the problem... because we cant see the shape or any of the angles for that manner.
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>.

Answer:
Yes.
Step-by-step explanation:
This problem has some different steps, so lets break it down:
Ed has 12 glasses of punch with 120 milliliters of liquid contained each.
Therefore, Ed has 12 * 120 milliliters of liquid:
Now, we need to convert to liters, because that is what Ed's possible answer unit is in. Since there are 1000 milliliters in a liter, we will divide 1440 by 1000.
Thusly, Ed is correct and the answer is 
.
Hope this helps! Have a nice day! ((:
