Answer:

Step-by-step explanation:

Given:

The scale 1 1/2 (\frac{3}{2}) inches = 15 feet

<=>  1 inch = \frac{15 feet}{\frac{3}{2} } = 10 feet.

<=> 1 feet = \frac{1}{10} inch

The dimensions of Sara's apartment are 22 1/2  (\frac{45}{2}) feet by 25 feet, so the new dimensions of Sara's apartment by inches are:

  • (\frac{45}{2}) feet = \frac{45}{2} * \frac{1}{10} = \frac{9}{4} inches
  • 25 feet = 25*\frac{1}{10} = \frac{5}{2} inches

Hope it will find you well.

Nathan just bought a car. He models the value, V, in dollars, of the car after t years as V(t)=21,000(0.861)^t. Based on this mo
Snezhnost [94]

Answer:

Value of the car is decreasing by 13.9% each year.

Step-by-step explanation:

This equation tells us V(t) is the value of the car after a certain time in years, $21,000 is the initial value of the car.  What we need to focus on is on the 0.861 part of this equation.  This means that the price of the car is worth 0.861 or 86.1% of what it was worth the year prior, this means that the price of the car is decreasing over time.  By how much is it decreasing? Well if we consider 1 to mean 100% (since 100 / 100 =1) then we have 100%-86.1%=13.9%.  This means that the value of the car is decreasing 13.9% each year.

A pail holds 6 3 4 gallons of water. How much is this in cups? Write your answer as a whole number or a mixed number in simplest
storchak [24]
I'm assuming the pail holds 6 3/4 (not 634) gallons of water.


1 gallon= 16 cups


Multiply total gallons by cups per 1 gallon.

= 6 3/4 cups * 16 cups/gallon
convert mixed number to improper fraction

= 27/4 * 16
multiply numerators

= (27*16)/4
multiply in parentheses

= 432/4

= 108 cups


ANSWER: There are 108 cups

Hope this helps! :)

12. What is the solution of the system of equations?
Nina [5.8K]

Answer:

no solution

Step-by-step explanation:

Hi there!

We are given this system of equations:

y=-2x+5

y=-2x+20

and we want to find the solution (the point in which the lines intersect)

There are 3 ways to solve a system, but let's use substitution in this case

Both equations are set to y, so they should be equal to each other via a property known as transitivity (if a=b and b=c, then a=c)

-2x+5=-2x+20 (the same as y=y)

Now let's solve for x

add 2x to both sides

5=20

In this case, we got an untrue statement. If this happens, then the lines won't intersect.

If they won't intersect, there's <u>no solution </u>

Hope this helps!
