Step-by-step explanation:

You know the angle sum is ...

  ∠FGT +∠TGH = ∠FGH

You can use this relation with the given values to find x.

 90 + (8x +4) = 39x +1

  93 = 31x . . . . . . . . . . . . . add -1-8x, collect terms

  3 = x . . . . . . . . . . . . . . . . divide by 31

Answer:

C) x=3

Step-by-step explanation:

(39x+1)-90=8x+4

39x+1-90=8x+4

39x-8x-89=4

31x=4+89

31x=93

x=93/31

x=3

What is the 200th odd number
Sonja [21]

1st one . . . . . 1
2nd one . . . . . 3
3rd one . . . . . 5
4th one . . . . . 7
5th one . . . . . 9
.
.
9th one . . . . . 17

It looks to me like the 'n'th odd number is always  (2n - 1) .

In that case, the 200th odd number is  (2x200 - 1)  =  <em>399 </em>.

I'll let you check it out and see if that's correct.

the length of a rectangle is more 3 more than the width. find the length of the rectangle if the perimeter is 98in​
Citrus2011 [14]
Let width be w
and length be l
therefore l = 3 + w

perimeter = 2( l + w )
98 = 2(3 + w + w)
98 = 6 + 2w + 2w
98 - 6 = 4w
92 = 4w
92/4 = w
23 = width
width = 23 inches

As l = 3 + w ,
so length = 26 inches

Hope this helps ♥

Calculate (a) the number of milligrams of metoclopramide HCl in each milliliter of the prescription:
nalin [4]

Answer:

There are 100 milligrams of metoclopramide HCl in each milliliter of the prescription

Step-by-step explanation:

When the prescription says Purified water qs ad 100 mL means that if we were to make this, we should add the quantities given and then, fill it up with water until we have 100 mL of solution, being the key words qs ad, meaning sufficient quantity to get the amount of mixture given.

Then, knowing there is 10 grams of metoclopramide HCl per 100 mL of prescription, that means there is (1 gram = 1000 milligrams) 10000 milligrams of metoclopramide HCl per 100 mL of prescription. That is a concentration given in a mass/volume way.

Knowing the concentration, we can calculate it per mL instead of per 100 mL

Concentration_{metoclopramide HCL}= \frac{10000mg}{100mL} =100 \frac{mg}{mL}
