Is 1/4 greater or less than 8/10

Write 2 equivalent fractions for the following fractions, use 2/2 and 3/3. 2/3

Valentin [98]

Answer:

$\frac{4}{4} ,\frac{5}{5}$

Step-by-step explanation:

In order to find the answer to this question you need to remember that if the denominator and the numerator are the same they equal one or one whole.

$\frac{2}{2} =1$

$\frac{3}{3}=1$

$\frac{4}{4}=1$

$\frac{5}{5} =1$

As long as the numerator and the denominator are the same they will be equivalent to 2/2 and 3/3.

Hope this helps.

The length of a rectangle is increased by 10 percent the width of a rectangle is increased by 5 find the percentage increased in

aalyn [17]

Answer: The percentage increase in perimeter is 7%.

Step-by-step explanation:

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(length + width)

The original length of the rectangle is 20 and the original width is 30. The original perimeter of the rectangle would be

Perimeter = 2(20 + 30) = 100

The length of the rectangle is increased by 10 percent. It means that the new length would be

20 + (0.1 × 20) = 22

The width of the rectangle is increased by 5 percent. It means that the new width would be

30 + (0.05 × 30) = 31.5

The new perimeter of the rectangle would be

Perimeter = 2(22 + 31.5) = 107

The increase in perimeter is

107 - 100 = 7

The percentage increase in perimeter is

7/100 × 100 = 7%

Simplify: -|-15| please answer correctly i'll give brainliest and 5-star rating.

12345 [234]

Answer:

-15

Step-by-step explanation:

Definition of absolute value:

Distance from zero on a number line.

Imagine a number line with 0 in the middle of it. Now mark the number 3 on it. Also mark the opposite of 3, which is -3. What is the distance from zero to those 2 points? it's 3.

This is exactly like saying |3| = 3 and |-3| = 3

Even if the number inside absolute value is negative, it simplifies to the positive of the same number.

_______________________________

So let's talk about your problem.

-|-15|

> the absolute value simplifies to 15

-|-15| = - 15

So that ends up being your answer.

$-15$

Hope this helps!!!!!!!

Use the Distance Formula and the Pythagorean Theorem to find the distance between each pair of points. M (10, −4) and N (2, −7)

xenn [34]

Answer:

$d=\sqrt{73}\approx8.54$

Step-by-step explanation:

So we have the two points (10,-4) and (2,-7).

And we want to find the distance between them using the Distance Formula and the Pythagorean Theorem. Let's do each one individually.

1) Distance Formula.

The distance formula is:

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

Let's let (10,-4) be (x₁, y₁) and let's let (2,-7) be (x₂, y₂). So:

$d=\sqrt{((2)-(10))+((-7)-(-4))^2$

Simplify:

$d=\sqrt{(2-10)^2+(-7+4)^2$

Subtract:

$d=\sqrt{(-8)^2+(-3)^2$

Square:

$d=\sqrt{64+9}$

Add:

$d=\sqrt{73}$

Approximate:

$d\approx8.54$

So, the distance between (10,-4) and (2,-7) is approximately 8.54 units.

2) Pythagorean Theorem

Please refer to the graph.

So, we want to find the distance. This will be the length of the red line, or the hypotenuse.

First, let's find the length of the two legs.

The longer leg will be the difference between the two x-coordinates. So, the length of the longer leg is:

$(10-2)=8$

Note: It doesn't matter if we do 2-10, which gives -8, since we are going to square anyways. Also, distance is always positive, so 8 would be our answer.

And the shorter leg is the difference between the two y-coordinates. Namely:

$(-7-(-4))=-3=3$
