4. Write the equation of the line that
passes through (9,4) (0-5)

Answers

Answer:

Equation of line is y = x - 5

Step-by-step explanation:

general equation of a line:

[tex]y = mx + c[/tex]

m » slope

c » y-intercept

for the slope, m :

[tex]slope = \frac{y_{2} - y_{1} }{x _{2} - x_{1} } [/tex]

substitute in accordance of the points:

[tex]slope = \frac{ - 5 - 4}{0 - 9} = \frac{ - 9}{ - 9} \\ \\ m= 1[/tex]

for y-intercept :

[ consider point (0, -5) ]

[tex]y = mx + c \\ - 5 = (0 \times 1) + c \\ c = - 5[/tex]

Therefore, equation of line is

[tex]{ \boxed{y = x - 5}}[/tex]

if 6 pipes fill a tank in 120 minutes, then 5 pipes can fill it in how many minutes​

Answers

Answer:

It'll take 144 minutes for 5 pipes.

Step-by-step explanation:

[tex]{ \sf{6 \: pipes = 120 \: mins}} \\ { \sf{5 \: pipes = ( \frac{6}{5} \times 120) \: mins}} \\ \\ = { \sf{144 \: mins}}[/tex]

but practically, it seems to be abnormal. if 6 pipes take 120 mins, 5 pipes must takes a time greater than 120 mins cause amount of water flowing to the tank is decreasing.

But there is a possibility that pressure of water was increased for the case of five pipes, that's why it takes a time less than 120 mins. (t < 120)

Answer:

144 minutes

Step-by-step explanation:

here we use inverse proportion because the more pipes there are the less time is needed

the formula for inverse proportion is y = k/x

first we need to find k which is the constant

if y is the number of minutes and x is the number of pipes we can substitute these into the formula like so: 120 = k/6

to find k rearrange the formula to get k = 6 * 120 = 720

now that we have k we can substitute 720 (k) and 5 (x) into y = k/x

y = 720 / 5

y = 144

(y is the number of minutes in this case so the answer is 144 minutes)

Ronnie sales wooden toothpicks it cost him $.10 to make a box of toothpicks he charges $1.20 per box toothpicks how many toothpicks does he need to sell to profit $1000

Answers

Answer:

910 boxes of toothpicks

Step-by-step explanation:

Create an equation to represent the situation, and let x represent the number of boxes of toothpicks.

1.20x - 0.1x = 1000

1.1x = 1000

x = 909.09

Round up to the nearest whole number:

= 910

So, Ronnie would have to sell 910 boxes of toothpicks to profit $1000.

Draw a line segment of length 6.4 cm and divide it in to 4 equal parts. Write the length of each part. (Draw clearly) ​

Answers

Answer:

The line drawn has a length of 6.4 cm.

Also it is divided into 4 equal parts.

Hence let the measure of the each equal part be ' x '

So x * 4 parts = 6.4 cm

=> x = 6.4 cm / 4

=> x = 1.6 cm

Hence the measure of each equal part is 1.6 cm.

Hence solved !

A property sells for $140,000 two years after it was purchased. If the annual appreciation rate is 6%, how much did the original buyer pay for it?

Answers

Answer:

$123,200

Step-by-step explanation:

0.06 x 2 = 0.12

140,000 x 0.12 = 16,800

140,000 - 16,800 = 123,200

The original buyer paid the amount of $123,200 for the property.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

The property appreciated by 6% per year, so in two years it would have appreciated by 6% × 2 years = 12%.

Once we know the total appreciation, we can subtract that value from 100% to find the original purchase price as a percentage of the final sale price.

If the property appreciated by 12%, then the original purchase price must have been 100% - 12% = 88% of the final sale price.

Now, multiply the final sale price by the original purchase price as a percentage to find the original purchase price.

So, the original buyer paid the amount = 88% × $140,000 = $123,200

Therefore, the original purchase price was $123,200.
