In Area A, the insurance coverage rate for a wood frame house is 0.46%. In Area B, the insurance coverage rate for a wood frame

Karo-lina-s [1.5K]

To solve for the homeowner's insurance payment for house built in Area B, we simply multiply the cost of the house with the insurance coverage rate in its decimal equivalent. From the given problem,
annual insurance payment = ($65,900)(0.0054)
= $355.86
Thus, the answer is letter A.

Victoria recently switched to a new electric company. If she uses between 0 and 400 kilowatt-hours (kWh) of electricity per mont

Gekata [30.6K]

Answer:

see the explanation

Step-by-step explanation:

The question is

Identify the domain and the range, using words and inequalities

Let

x -----> the number of kilowatt-hours (kWh) of electricity per month

y ----> the price per month

we know that

Part 1) For the value of x between 0 kWh and 400 kWh

$0\ kWh \leq x < 400\ kWh$

The price is equal to

$y=\$30$

therefore

The domain is the interval ------> [0,400)

The domain is all real numbers greater than or equal to 0 kWh and less than 400 kWh

The range is ($30)

The range is equal to $30

Part 2) For the value of x equal to 400 kWh or more per month

$x\geq 400\ kWh$

The domain is the interval -----> [400, infinite)

The domain is all real numbers greater than or equal to 400 kWh

The price is

$y=0.097x$

Find the range

For x=400 kWh

$y=0.097(400)=\$38.8$

$y\geq \$38.8$

The range is the interval -----> [38.8, infinite)

A plane can fly 11 miles per minute. The plane will fly 6 trips, and each trip is 500 miles. How many hours will the plane fly?

BabaBlast [244]

Answer:

4 hours 33 minutes

Step-by-step explanation:

multiply the distance of each trip by the amount of trips taken to find the total distance traveled:

500x6=3000 miles

time=distance/speed:

3000/11= apro 273 mins

= 4 hours 33 minutes
