For Simple Interest, I = PRT/100

Time = 1 year.

I = P*R*1/100

100*I =  PR

100I / P = R

The formula for the Rate, R = 100I / P.

At an aquarium, 6 out of 18 deliveries are plants. The aquarium is making 15 deliveries next week and wants to use a proportion
stealth61 [152]

Answer:

I think 5 of the 15 deliveries are plants.

Step-by-step explanation:

I divided 6 by 18 to get 3.4 (I rounded up), which translates to 34%. 34% of 15 is 5.1, I rounded to get 5.

I checked my work by getting 34% of 18, which is 6.12 and would round to 6.

How many distinct triangles can be formed for which m∠E = 64°, g = 9, and e = 10?<br> triangle(s)
Shalnov [3]

Using the law of sines, it is found that 1 triangle can be formed with the given conditions.

<h3>What is the law of sines?</h3>

Suppose we have a triangle in which:

  • The length of the side opposite to angle A is a.
  • The length of the side opposite to angle B is b.
  • The length of the side opposite to angle C is c.

The lengths and the sine of the angles are related as follows:

\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}

Hence, for this problem, we have that the relation is:

\frac{\sin{64^\circ}}{10} = \frac{\sin{G}}{9}

\sin{G} = 0.9\sin{64^\circ}

\sin{G} = 0.8089

G = \arcsin{0.8089}

G = 54º

A triangle can have one angle of 64º and another of 54º, hence 1 triangle can be formed with the given conditions.
