This is an arith. sequence, and the common difference is -9.
a(n+1) = a(n)-9, with a(1)=8. Thus, if we look at the first term, we see 8; subracting 9 from 8 produces the second term (-1).
Answer:
T<7
Step-by-step explanation:
21+7T+8<43
29+7T<43
7T<43‒29
7T<14
7T/7<14/7
T<7
i think it is clear &i hope it helps you
Answer:
Step-by-step explanation:
Sin(30) / X = Sin(45) / 12
use algebra to isolate X
1 / X = [ Sin(45) / 12 ] / Sin(30)
flip both sides
X = Sin(30) / [Sin(45) /12 ]
invert the denominator on the right side
X = Sin(30) * 12/ Sin(45)
Do you know what Sin(30) is off the top of your head?
and also Sin(45) ?
these are worth remembering... and you can b/c they are just
sin(0) = 0/2
sin(30) = 1 / 2
sin(45) =
/2
sin(60)=
/ 2
sin(90) =
/ 2 (aka 1)
note the numerators just counts up 0, 1, 2, 3, 4 :)
Cos works the same way but counts from 90° back to 0 but exactly like sin other wise, hence why Cos and Sin both =
/2 at 45 °
anyway
X = 1 / 2 * 12/
/2
X = 3
A=3
B= 2
:) nice , huh
The correct answer is 16737 mg
Explanation:
The first step to solve this problem is to convert the weight to kilograms because the dosage of the antibiotic is given in milligrams per kilo. This can be done by multiplying the pounds by 0.453 considering each pound is equal to 0.453 kilos. The process is shown below:
123 lb x 0.453 = 55.791 kg
Now, simply multiply the kilos by the recommended dose:
55.791 kg x 300 mg/kg = 16737 mg
Also, this can be converted to grams by dividing the number into 1000 (1000 mg = 1 g)
16737mg ÷ 1000 = 16.737 grames
