Answer:

1. B (firefighter question) 2. A (dance lesson fee question) 3. A (dolphin question)

Step-by-step explanation:

1. The firefighters gear PLUS his weight is how much he weighs in total.

2. An added fee is usually represented as a registration fee or staring fee. There was 45w which should represent the fee she paid every week.

3. The dolphin swims at a rate of 25 kilometres per hour. The graph represents the distance the dolphin traveled because in two hours the dolphin would travel 50 kilometres (25 kilometres*2 hours) and so on.

Jim went by bus to visit his uncle. He left at 10 A.M. and arrived at 4 P.M. The bus traveled 270 mi. What was its average speed

Feliz [49]

Answer:

Average speed, S = 45 mph

Step-by-step explanation:

Given the following data;

Take-off time = 10 AM

Arrival time = 4 PM

Distance = 270 miles

To find the average speed of the bus;

First of all, we would determine the total time.

10 AM to 4 PM = 6 hours

Total time = 6 hours

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

$Speed = \frac{distance}{time}$

Substituting into the formula, we have;

$Speed = \frac{270}{6}$

Average speed, S = 45 mph

Therefore, the average speed of the bus is 45 miles per hour.

An investment made in the stock market decreased at a rate of 1.2% per year for 25 years. What is the current value of the $100,

densk [106]

Use A = P (1 + r/n) ^(nt). Assuming that we're dealing with years here, n = 1, so we have

A = P (1 + r) ^(t), where r is the interest rate as a decimal fraction.

The investment decreases in value, so the common ratio r is (1.000-0.012), or 0.988.

Thus, A = $100,000* (0.988) ^25 = $73947.52 is the current value, after 25 years.
