Answer:

$45

Step-by-step explanation:

We are given the following information;

  • Money invested (Principal) is $300
  • Rate of interest is 5% per annum
  • Time the money is invested is 3 years

We need to determine the amount of interest the money will earn after three years.

  • Simple interest is calculated by the formula;
  • Simple interest =(PRT) ÷ 100, Where P is the principal amount, R is the rate of interest and T is the time.

Therefore, in this case;

Simple interest = ($300 × 5 × 3) ÷ 100

                         = $45

Thus, the money invested earned a simple interest of $45

Two vehicles are driving along a straight roadway at a constant speed. At a certain point in time, a car is 1.2 miles away from
Maurinko [17]

Answer:

The expression for the total distance between the car and the landmark in terms of the number of hours spent driving is given as follows;

1.2 = 65 × t

Where t = 1.2/65 = 0.0185 h = 66.46 seconds

Step-by-step explanation:

The parameters given are;

Distance, d between car and landmark = 1.2 miles

Speed of car = 65 miles/hr

Distance between truck and landmark = 0.7 miles

Speed of car = 55 miles/hr

The expression for the total distance between the car and the landmark as a function of time t is given as follows;

Distance, d = Speed, v × Time, t

Therefore, the expression for the total distance between the car and the landmark in terms of the number of hours spent driving is given as follows;

1.2 = 65 × t

Where t = 1.2/65 = 0.0185 h = 66.46 seconds.

When Gene and Kelly were planning their trip to Paris, one United States dollar was worth about $\frac{7}{10}$ of a euro. Before
Andre45 [30]

Answer:

$280 dollars

Step-by-step explanation:

When they were leaving

\$1 \approx \frac{7}{10}$ Euro\\Therefore:\\\$1000 \approx  \dfrac{7}{10}\times 1000 =700$ Euro

When they returned home, they brought 196 Euros.

If\:\:\$1 \approx \frac{7}{10}$ Euro\\Then: 1 Euro $=\$  \dfrac{10}{7}\\\\$Therefore:\\\\196 Euros = \$ 196 \times \dfrac{10}{7} =\$280

They brought back $280 dollars to the United States.

jek_recluse [69]

Answer:

0.278

Step-by-step explanation:

Given that Nuri joins a game for a car. The rule is that Nuri pick one key from box either A, B, or C. A box has two keys but only one can be used. B box has three keys but only one can be used. C box has two keys but none of them can be used.

Each box is equally likely to be selected.

In other words

P(A) = P(B) = P(C)=\frac{1}{3}

If A is selected then probability of winning is using the correct key out of two keys i.e. 0.5

If B is selected then probability of winning is using the correct key out of three keys i.e. 0.333

If c is selected then probability of winning is using the correct key out of two keys i.e. 0.00

So the probability that Nuri can win the car

= \frac{1}{3} *0.5+\frac{1}{3} *0.333+\frac{1}{3} *0\\= 0.278

Law of sines: StartFraction sine (uppercase A) Over a EndFraction = StartFraction sine (uppercase B) Over b EndFraction = StartF
vladimir2022 [97]

Answer:

30°

Step-by-step explanation:

Law of Sines = \frac{a}{Sin A} = \frac{b}{Sin B} = \frac{c}{Sin C}

\frac{2}{Sin 30} = \frac{2}{Sin B}

\frac{2}{Sin 30} = \frac{2}{Sin 30}

Therefore, m∠B = 30°

Hope that's right and helps
