Rewrite 7.25 as a mixed number in lowest terms

1 answer:

7 0

7.25 as a mixed number

7 is a whole number

0.25 is 25/100

7 25/100

As a lowest term, simplify the 25/100

Divide 25 top and bottom

25/25 = 1
100/25 = 4

7 1/4 is your answer

hope this helps

What is the formula to find distance in coordinate geometry, given coordinates (x_1, y_1), (x_2, y_2)? (valid variables for this

madreJ [45]

Answer:

The distance formula is: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Given:

Two points on a coordinate plane are given as:

$(x_1,y_1)\ and\ (x_2,y_2)$

Now, let the points be $A(x_1,y_1)\ and\ B(x_2,y_2)$ and let 'd' be the distance between the two points.

Now, join the points A and B to make a line segment AB.

Also, draw a right angled triangle ABC right angled at point C. Point C is is the intersection of horizontal and vertical lines drawn from points A and B respectively as shown in the figure below.

From the triangle ABC, we observe that:

AB = $d$

AC = $x_2-x_1$

BC = $y_2-y_1$

Now, we use Pythagoras theorem to find 'd'. This gives,

$AB^2=AC^2+BC^2\\\\d^2=(x_2-x_1)^2+(y_2-y_1)^2$

Now, taking square root on both sides, we get:

$\sqrt{d^2}=\pm\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Ignoring the negative result as distance can never be negative.

Therefore, the formula to find distance in coordinate geometry, given coordinates $(x_1, y_1), (x_2, y_2)$ is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

A park has a large circle painted in the middle of the playground area. The circle is divided into 4 equal sections, and each se

oee [108]

First you need to find the area of the whole circle. $\pi r^{2}$
The radius is given as 10, so just insert 10 into the equation of the area of a circle equation.
$Area = \pi 10^{2} Area = 100 \pi$
Putting $\pi$ after the 100 because that is what is commonly done.

Because the circle is then being split into 4 equal sections, we need to find 1/4 of the area of the whole circle to find the area of one of these sections.

Since the area of the whole circle is $100 \pi$ then we just divide that by 4,
leaving us with 25 $\pi$ and that is our final answer

What is the slope of a line perpendicular to the line with equation y = 1/6x – 2? help pls very urgent

valina [46]

Solution:

1) Simplify \frac{1}{6}x to \frac{x}{6}
y=\frac{x}{6}-2

2) Add 2 to both sides
y+2=\frac{x}{6}

3) Multiply both sides by 6
(y+2)\times 6=x

4) Regroup terms
6(y+2)=x

5) Switch sides
x=6(y+2)

Done!
