Answer:
8 is the correct answer because coefficient lies before Exponent. Exponent is variable
So 8 is the coefficient.
Answer:
Step-by-step explanation:
The sides AB and CD are parallel to the x-axis and 5 units apart. The length of side AB is 6-(-12) = 18 units. The area is the product of these dimensions:
Area = (Base)(Height) = (18 units)(5 units) = 90 units²
Answer:
the trainee calculated the incorrect amount
It should be 0.5 mL
Step-by-step explanation:
The physician orders penicillin 500,000 units for a patient while the concentration of the drug you have is 1,000,000 units/ 1mL. It's clear that 1mL drug is too much for the patient since 1,000,000 units are higher than 500,000 units.
The amount of penicillin in 1.5 mL will be definitely higher than 1,000,000 units, so it must be a lot higher than the physician's orders. We can roughly guess that the trainee draws an incorrect amount.
To calculate the exact volume you need, you have to divide the amount of the drug you need with the concentration of the drug. The calculation will be:
the volume needed = amount of the drug you need/ concentration of the drug
volume needed = 500,000 units / (1,000,000 units/ 1mL)= 1/2 mL = 0.5 mL
Answer:
There are 26 purple marbles in the bag.
Step-by-step explanation:
1) We have purple (p) and blue (b) marbles in a bag, and 41 marbles total so:
p+b = 41
2) we want to know how many purple marbles we have, so let's rearrange for p:
p = 41 - b
3) Our problem gives us an expression for the purple marbles in terms of the blue, let's write it using math symbols instead of words:
<em>"The number of purple marbles is 4 less than 2 times the number of blue marbles."</em>
so: p = 2b - 4
3) Now we're going to plug this in (or substitute it) for our p in our first equation, and solve for b
p = 41 - b
2b - 4 = 41 - b (substitution)
2b = 45 - b ( add 4 to both sides)
3b = 45 (add b to both sides)
b = 15 (divide both sides by 3)
4, last step!)
Now we know we have 15 blue marbles, that's great! But we still want to know how many purple marbles we have.
41- 15 = 26 purple marbles
