PLEASE HELP IT'S ON A TEST!

What is an equation of the line that passes through the point (2, 4) and is perpendicular to the line whose equation is y = 2x + 1?

See attachment for math work and answer.

40/ 1/4

40 x 4 = 160

160 is greater than 1/4

Any number that is greater than 0.25 can be your answer

Hope this helps :)

Answer: 272%

Step-by-step explanation: To write 136/50 as a percent have to remember that 1 equal 100% and that what you need to do is just to multiply the number by 100 and add at the end symbol % .

136/50 * 100 = 2.72 * 100 = 272%

And finally we have:

136/50 as a percent equals 272%

Water Street intersects 25th Street and 28th Street at right angles.

Highway 47 is parallel to 28th Street.

GiveN:

What to do?

Step-wise-Step Explanation:

If wall Street intersects 25th Street and 28th Street at right angle then they will Parallel (||) to each other. Because,

Now Highway 47 is parallel to 28th Street. It means 25th Street is also parallel to Highway 47 because,

Thus, They are Highway 47 and 25th Street are parallel to each other. (Answer)

Answer:

prime Number

Step-by-step explanation:

because 2 can be only divided by itself and one

Answer:

the number 2 is the only even prime number

Average Speed = Total Distance / Total Time

Total Distance = 400m + 600m = 1,000m

Total Time = 35s

Average Speed = 1,000/35 = 28.57 m/s (approx.)

Average Speed in two decimal places is 28.57 m/s (approx.)

▹ Answer

1/18 of a gallon of juice in each cup.

▹ Step-by-Step Explanation

Since we have 4/9 of a gallon of juice for 8 cups, we will divide to find the amount of juice in each cup.

[tex]\frac{4}{9} / 8[/tex]

Since this operation is division, we have to change 8 to it's reciprocal which is 1/8:

[tex]\frac{4}{9}/ \frac{1}{8} = \frac{4}{72} = \frac{1}{18}[/tex]

Our final answer will be 1/18 of a gallon of juice in each cup.

Hope this helps!

=============================================

Explanation:

Part (1) Finding the mean

Add up the values to get

80 + 90 + 10 + 75 + 90 + 95 + 99 = 539

Then divide by 7 because there are 7 values in this list

539/7 = 77

The mean is 77

--------------------------

Part (2) Finding the median

First we'll need to sort the values from smallest to largest

{80, 90, 10, 75, 90, 95, 99}

will sort to

{10, 75, 80, 90, 90, 95, 99}

The middle most value is 90 since we have three items below it {10,75,80} and three items above it {90, 95, 99}.

The median is 90

--------------------------

Part (3) Which is the better measure of center?

Nearly all of the values are clustered from 75 to 99. The value 10 is an outlier since it's far from the main cluster. There are more technical processes used to find out if 10 is actually an outlier or not, but we won't deal with that right now.

The much smaller outlier pulls on the mean to make it smaller than what it should be. The mean 77 is too small to represent what the center should be. The median is not affected by outliers, which is why it's used in applications such as home prices.

The median 90 is the better measure of center.

Step-by-step explanation:

The question is incomplete. However, the available details is enough to work out a solution.

Considering the first even number: 2

In this case, n = 1

The sum of the first even term is 2.

Represent the sum as a product:

[tex]2 = 1 * 2[/tex]

Considering the first two even numbers: 2 and 4

In this case, n = 2

The sum of the first two even terms is 6

Represent the sum as a product:

[tex]6 = 2 * 3[/tex]

Considering the first three even numbers: 2, 4 and 6

In this case, n = 3

The sum of the first two even terms is 12

Represent the sum as a product:

[tex]12 = 3 * 4[/tex]

Notice the pattern from n = 1 to 3

[tex]2 = 1 * 2[/tex] --- n = 1

[tex]6 = 2 * 3[/tex] --- n = 2

[tex]12 = 3 * 4[/tex] --- n = 3

------------------------------------

It follows that, the sum when represented as a product is: [tex]n * (n + 1)[/tex]

So, the sum of the first 52 even terms would be:

[tex]52 * (52 + 1)[/tex]

Where n = 52

[tex]52 * (52 + 1) = 52 * 53[/tex]

[tex]52 * (52 + 1) = 2756[/tex]

Hence, the sum of the first 52 even terms is 52 * 53 or 2756

Answer:

The amount of $1000 principal is needed to have $3000 after 5 years.

Step-by-step explanation:

As the interest formula is

[tex]I=Prt[/tex]

Where

Substituting the following values in the interest formula and solve for P

I=$3000

r = 6% = 6/100 = [tex]0.06[/tex]

t = 5

so the equation becomes

[tex]I=Prt[/tex]

[tex]3000=P\left(0.06\right)\left(5\right)[/tex]

switch both sides

[tex]P\left(0.06\right)\left(5\right)=3000[/tex]

[tex]P\left(0.3\right)=3000[/tex]

[tex]P=10000[/tex] $

Therefore, the amount of $1000 principal is needed to have $3000 after 5 years.
