Answer:
The equation to find the total yards of lace Fern need is .
Fern will need 6 yards of lace in total.
Step-by-step explanation:
Given:
Yard of lace required for each napkins =
Number of napkins needs to put lace = 10
We need to Write an equation to solve this and explain how many yards of lace Fern will need total.
Solution:
Let the total yards of lace Fern need be 'x'.
So we can say that;
total yards of lace Fern need can be calculated by multiplying Yard of lace required for each napkins with Number of napkins needs to put lace .
framing in equation form we get;
Hence the equation to find the total yards of lace Fern need is .
On solving we get;
Hence Fern will need 6 yards of lace in total.
Answer:
triangle ABC is "not" a right-angled triangle
Step-by-step explanation:
AB=8cm
BC=5cm
perimeter = 22cm
CA = 22 - 8 - 5 = 9
8² + 5² = 89
9² = 81
AB² + BC² ≠ CA²

Change mixed numbers to improper fractions. Then change division to multiplication by the reciprocal.
1 1/2 divided by 3/5=
(3/2) * (5/3) = 5/2 = 2 1/2
#3
(5/9) divided by (5/3)
(5/9) * (3/5) =3/9 = 1/3

Step-by-step explanation:
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
