The answer is A. 0.4691 g
1 g = 1000 mg
⇒ 1 mg = 1/1000 g
<u>1 mg = 0.001 g
</u>469.1 mg = 469.1 * 1 mg = 469.1 * 0.001 g = 0.4691 g<u>
</u>
Answer:
75 units²
Step-by-step explanation:
PL² = 6² + 8²
PL² = 100
PL = 10
Triangles PAL and MPL are similar triangles
6/8 = PM/10
PM = 10 × 6/8 = 7.5
Area = 7.5 × 10
75 units²
You have to find the cos of angle A, so use the Pythagorean equation and trig laws to find the other side of the triangle created by angle A. 3^2 + x^2 = 5^2. x=4. This means cos(A) = 4/5). Make both cos (A) and cos (B) have equal denominators, and add. 148/185 + 60/185 = 208/185. This answer is correct, though it doesn’t appear to be any of the answers you wrote, so either those answers are wrong or you wrote something incorrectly in the problem.
Answer:

13 glue sticks cost $25.22.
Step-by-step explanation:
4 blue sticks cost $7.76, this means that one glue stick costs
$7.76/4 = $1.94.
Let
be the cost of the glue sticks, and
be the number of glue sticks; then

We can use this equation to find the cost of 13 glue sticks; we just put
into our equation and it gives:

So 13 glue sticks cost $25.22.
