Answer:

m= -84

Step-by-step explanation:

Step 1- Multiply both sides by 7

42-m= 126

Step 2- Move constant to the right hand side and change its sign

-m= 126-42

Step 3- Subtract the numbers

-m= 84

Step 4- Change the signs on both sides of the equation

m= -84

A car with an initial cost of $33,000 is decreasing in value at a rate of 7% each year. Write the exponential decay function to
Brut [27]

Answer:

n= 11.65 years

Step-by-step explanation:

Giving the following information:

Present Value (PV)= $33,000

Future Value (FV)= $15,000

Decrease rate (d)= 7%

<u>To calculate the number of years it will take to reach $15,000; we need to use the following formula:</u>

<u></u>

n= ln(FV/PV) / ln(1+d)  

n= ln(15,000/33,000) / ln(1.07)

n= 11.65 years

The angle of YWZ is equal to the angle of YWX, and angle WYX is also a right angle due to the congruency of segments WZ and WX.

Every triangle has an angle total of 180 degrees, so angle WXY is equal to

180 - (WYX + YWX)
180 - (90 + 17)
73

Angle WXY has an angle value of 73 degrees.

Chip and dale are driving in a toy engine around the Christmas tree at a speed of 300 miles/hour. how many minutes will it take
Deffense [45]

Using proportions, it is found that it will take them 0.00248548 minutes to do one loop.

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

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, according to their speed, in 60 minutes, they drive 300 miles. In how many minutes will they drive 20 m = 0,0124274 miles?

The <em>rule of three</em> is:

60 min - 300 miles

x min - 0.0124274 miles

Applying cross multiplication:

300x = 60 \times 0.0124274

x = \frac{60 \times 0.0124274}{300}

x = 0.00248548

It will take them 0.00248548 minutes to do one loop.
