Kim picked 250 pounds of pears yesterday and 287 pounds of pears today. What is the percentage increase of

xxMikexx [17]

Given:

Kim picked 250 pounds of pears yesterday and 287 pounds of pears today.

To find:

The percentage increase of amount of pears picked by Kim.

Solution:

We know that,

$\%\text{ increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100$

$\%\text{ increase}=\dfrac{287-250}{250}\times 100$

$\%\text{ increase}=\dfrac{37}{25}\times 10$

$\%\text{ increase}=\dfrac{370}{25}$

$\%\text{ increase}=14.8$

Therefore, the percentage increase of amount of pears picked by Kim is 14.8%.

Which expression is equivalent to 5!<br> 5^4*3^2<br> 5-4-3-2-1<br> 5.4.3-2.1<br> 5+4+3+2+1<br> 5.1

baherus [9]

The first one is like 5x5x5x5 which is 625 multiplied by 3x3 which is 9 and together the product will be 5,625.

The second one is 5-4 which is 1-3 which is -2 - 2 = -4 - 1 which is -5 so it’s not it because it’s the opposite of the number we need to find.

The third one is kind of messed up because there’s no such thing as 5.4.3 so sorry I can’t do that one.

The fourth one is 15 because you basically add the numbers up.

And the fifth is not 5. It’s 5.1 so that’s not it either.

So I’m sorry I can’t find the answer but at least I have you some background :/

An equation of the perpendicular bisector of the line segment with end points (3,0) and (-3,0) is

Norma-Jean [14]

Answer:

$x = 0$

Step-by-step explanation:

Given

$(x_1,y_1) = (3,0)$

$(x_2,y_2) = (-3,0)$

Required

The equation of the perpendicular bisector.

First, calculate the midpoint of the given endpoints

$(x,y) = 0.5(x_1 + x_2, y_1 + y_2)$

$(x,y) = 0.5(3-3, 0+ 0)$

$(x,y) = 0.5(0, 0)$

Open bracket

$(x,y) = (0.5*0, 0.5*0)$

$(x,y) = (0, 0)$

Next, determine the slope of the given endpoints.

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{0 - 0}{-3- 3}$

$m = \frac{0}{-6}$

$m = 0$

Next, calculate the slope of the perpendicular bisector.

When two lines are perpendicular, the relationship between them is:

$m_2 = -\frac{1}{m_1}$

In this case:

$m = m_1 = 0$

So:

$m_2 = -\frac{1}{0}$

$m_2 = unde\ fined$

Since the slope is $unde\ fined$ , the equation is:

$x = a$

Where:

$(x,y) = (a,b)$

Recall that:

$(x,y) = (0, 0)$

So:

$a = 0$

Hence, the equation is:

$x = 0$
