Ned is driving at 72km/h, at this rate how long (in hours and minutes) will it take him to drive 210km
beks73 [17]

Answer:

2 hours 55 minutes

Step-by-step explanation:

calculate time (T) using the relationship

T = \frac{D}{S} ( D is distance , S is average speed )

T = \frac{210}{72} = 2.9166... hours

to convert to hours and minutes multiply the decimal part by 60 , that is

0.9166.. × 60 = 55 minutes

then time taken to drive 210 Km is 2 hours 55 minutes

Ann weighs 259 pounds but is only 5 feet 3 inches tall. Betty is 6 feet tall. How much would you expect Betty to weigh if they h
Tom [10]

Answer:

D. 296.00 LBS

Step-by-step explanation:

We convert both heights to inches.

1 ft = 12 in.

5 ft 3 in = 5 × 12 in. + 3 in. = 63 in.

6 ft = 6 × 12 in. = 72 in.

\dfrac{63~in.}{259~lb} = \dfrac{72~in.}{x}

\dfrac{63x}{259} = 72~lb

x = \dfrac{259 \times 72~lb}{63}

x = 296~lb

Answer: D. 296.00 LBS

Which of the following situations describes a function? Remember you are looking for an independent variable and a dependent var
BlackZzzverrR [31]

The situation that is a function is: C. The weight of a package and the cost of postage.

<h3>What is a Function?</h3>

A function can be described as a relation whereby there can only be one exact possible output value (dependent variable) for every input value (independent variable) in the relation. This means, no input value has two different output values. However, two different input values can have the same output value.

In a function, the output value is dependent on the input value.

For example, the cost of postage (output) is dependent on the weight of a package (input).

Therefore, the situation that is a function is: C. The weight of a package and the cost of postage.
