Step-by-step explanation:
the perimeter is
2×length + 2×width = 1030 ft
length + width = 515 ft
length = width + 181
now we use that in the first equation :
(width + 181) + width = 515
2×width + 181 = 515
2×width = 334
width = 167 ft
because of
length = width + 181
length = 167 + 181 = 348 ft
Answer:
g = 3
Step-by-step explanation:
(x+7)(x-4) = x²+ gx -28
Multiply the two parenthesis
(x+7)(x-4)= x² -4x +7x -28
Combine like terms
(x+7)(x-4)= x²+3x-28
Compare the equations
x²+ gx -28 = x² +3x -28
g = 3
Help different samples with different types of run D. So 2.34 is correct
First, you need to convert all units to calculate what dose the doctor ordered.
1 dram = 4 mL
So, it must be given 4 mL of medication
1 cc = 1 mL
So, if t<span>he vial states that there is 1 mg in 1 cc </span>, that means the concentration is 1 mg in 1 mL or, 1 mg/mL.
Now, we need to calculate what is the dose of medication in 4 mL:
1 mg is in 1 mL, how many mg is in 4 mL:
1 mg : 1 mL = x : 4 mL
Crossing the products:
x · 1 = 1 mg · 4
⇒ x = 4 mg
