mr henderson mixed 3.732g of chemical A, 13.902 of chemical B and 5.208g of Chemical C to make 3 does of medicine, About how muc
Dafna11 [192]

Answer:

22.8 grams

Step-by-step explanation:

To find total amount of medicine, we have to add all the 3 quantities of Chemical A, Chemical B, and Chemical C.

Before we do that, we have to round up each quantity to the nearest tenths.

Nearest tenths means we can take "1 digit" after the decimal point. For that we use rounding rules.

If the 2nd digit to the right of decimal is 5 or greater, we round up the 1st digit to the next whole number. If the 2nd digit is less than 5, we keep the 1st digit same.

So, using that we round up each of the three numbers as shown:

3.732 becomes 3.7 (since 3 is less than 5, we keep the 7)

13.902 becomes 13.9 (since 0 is less than 5, we keep 9)

5.208 becomes 5.2 (since 0 is less than 5, we keep 2)

Now we add:

3.7 + 13.9 + 5.2 = 22.8 grams

I need help as soon as possible
mote1985 [20]
The sin ratio is the side opposite the reference angle over the hypotenuse.  If Z is our reference angle, then the side opposite it has a length of 32.  The hypotenuse has a length of 40.  Therefore, the sin of Z = 32/40.  We will reduce that to sin Z = 4/5.  First choice above.
