You need to know that:
1 ounce = 28.35 grams
So, 1 tube contains
3.0 oz × 28.35 = 85.05g total mass
Mass of Benzyl salicylate =
2.40/100 = Percentage of Benzyl salicylate (in numerical value)
= 0.024
0.024 × 84 = Mass of Benzyl Salicylate
=2.016g
If one tube contains
2.016g × 425 tubes
=856.8g
Then,
Converting into kg by (dividing by 1000)
=856.8 ÷ 1000
= 0.8568 grams
= 0.857g (3sf)
Answer:
x-y
Step-by-step explanation:
when you subtract (-2x-8y)-(-3x-7y)
you have to distribute that negative onto -3x-7y which turns it positive
which results in -2x-8y+3x+7y
simplified to x-y
Answer:
A) 6.32 in.
B) 71.56°
C) 36.88°
Step-by-step explanation:
To solve each part of the problem, let's pay attention to the triangle ABC shown in the figure.
A) The slant height (l) of the cone is the hypotenuse of the right triangle ABC, then, to calculate it you can apply the Pythagorean Theorem:
B) The angle asked is the angle ∠A, then, you have:
∠°
C) The angle formed between the segments (which you can call α) that represent the slant heights is twice the angle ∠C.
By definition, the sum of the interior angles of a triangle is 180°,so you can calculate the angle ∠C as following:
∠
Then:
°
I'm pretty sure it would be 4 20÷5=4
