What’s the distance between (3,4) , (7,2)

Answers

Answer 1

Answer:

Answer:

$D= 4.47$

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

$D=√((y_2-y_1)^2+(x_2-x_1)^2)$

Where

$(x_1,y_1) = (3,4)$

$(x_2,y_2) = (7,2)$

Replacing these values in the distance formula

$D =√((7-3))^2+(2-4)^2)$

$D =√((4)^2+(-2)^2)$

$D =√(16+4)$

$D =√(20)$

$D= 4.47$

the table shows two options provided by high speed internet. option 1 have set up fee of $50 with $30 per month. option 2 have no set up fee and is $40 per month. in how many months will the total cost of both options be the same? what will that cost be? if you plan to cancel your internet service after 9 months, which is the cheaper option?

Answers

Let us take the case of first option first
Set up fee that need to paid = $50
Per month charge of using internet = $30
Now let us take the case of the second option
Set up fee that need to be paid = $0
Per month charge of using the internet = $40
Let us assume the number of months after which both options will be same = x
Then
50 + 30x = 40x
40x - 30x = 50
10x = 50
x = 50/10
= 5
So after 5 months both the options will be same
Now to find the cost after 5 months
we can take any option for calculating = 40x
= (40 * 5) dollars
= 200 dollars
So after 5 months that amount that need to be paid is $200 for any of the plans
In case of the first option,
Cost after 9 months = 50 + 30x
= 50 + (30 * 9)
= 50 + 270
= 320 dollars
After 9 months the cost using second option = 40x
= (40 * 9)
= 360 dollars
So after 9 months the first option will be cheaper.

Landon and Keira are preparing refreshments for a party. To make fruit punch, they will mix 2 gallons of grape juice with 1 cup of lemonade and 6 ounces of pineapple juice. How many ounces of punch will they make?

Answers

Answer:

270.12 ounces of punch.

Step-by-step explanation:

Landon and Keira are preparing refreshments for a party.

To make fruit punch, they will mix grape juice = 2 gallons

Lemonade = 1 cup

Pineapple juice = 6 ounces.

Now we convert all the units into ounces.

1 gallon = 128 ounces

they use 2 gallon = 256 ounces

1 cup = 8.12 ounces

Now add all the liquids = 256 + 8.11537 + 6 = 270.12 ounces.

They would make total 270.12 ounces of punch.

Convert everything to oz2 gal= 256 oz1 cup= 8 oz256+8+6= 270 ozThey will make 270 oz of punchHope I helped!!! :-)

A count went from 605 to 203. What was the approximate percent decrease? Round the numbers to find an estimate of the percent decrease. The percent decrease was approximately 25%. The percent decrease was approximately 33%. The percent decrease was approximately 50%. The percent decrease was approximately 66%.

Answers

66% It is 66% because 203 is less than half of 605. So, you would add that together. 203+203=406 Thats not even close to 605 so now you add almost half so that would be about 66%

Answer:

Decrease was 66%

What is 16/1000 simplified?

Answers

The simplified expression of 16/1000 is 2/125

How to simplify the expression

From the question, we have the following parameters that can be used in our computation:

Fraction = 16/1000

Divide 16 and 1000 by 8

So, we have the following representation

Fraction = 2/125

Hence, the simplified expression of 16/1000 is 2/125
