Yvette is trying to calculate the distance between point C(1, 2) and point D(7, 10). Which of the following expressions will she use?

Answers

Answer 1

Answer: For the answer to the question above, this can be solve using the distance formula: D = sqrt [ (x2 – x1)^2 + (y2 – y1)^2] So the expression she should use is: D = sqrt [ (7 – 1)^2 + (10 – 2)^2] Then the answer would be: D = sqrt [ (6)^2 + (8)^2] D = 10 I hope my answer helped you.

Answers

How many tiles does she need ?

1 square meter = 10,000 cm²
12 square meters = 120,000 cm²
Each tile = (20 cm x 20 cm) = 400 cm²
Tiles needed = 120,000 / 400 = 300 tiles

How many tiles can she buy ?

1,000 / 34.99 = 28 boxes, with 20.28 left over . . . not enough for another box.
28 boxes of 10 tiles per box = 280 tiles

Halima doesn't have enough money to buy enough tiles
to cover the wall. She can only buy 280 tiles, but it would
take 300 to cover the wall.

She can cover 280/300 = 93 and 1/3 percent of the wall,
leaving 6 and 2/3 percent with the old ugly plaster showing.
Maybe she could leave the bare part down at the bottom, and
then hide it with a table up against the wall.

im pretty sure she can only cover 380 of it

Remember, one whole circle is 360 degrees. This means that the side that looks to be the same as 43 degrees is 43 degrees. The side that looks the same as (6x+5) should be (6x+5).

Now just set up your equation like this and solve:

43+43+6x+5+6x+5=360

Hope I could be of help! :)

What is the simplified expression for 5ab+9ab-ab?

Answers

Answer:

The simplified form of the given expression is $13ab$ .

Step-by-step explanation:

We are given the expression,

$5ab+9ab-ab$

Using the order of operations rule, we have,

First we will add the terms 5ab and 9ab.

So, the expression is $14ab-ab$

Now, we will subtract the terms to get the final answer,

That is, $5ab+9ab-ab$ = $13ab$

Hence, the simplified form of the given expression is $13ab$ .

Remember the order of operations, pemdas, add 5ab and 9ab to get 14ab, then subtract to get 13ab

How do i find the fourth side of quadrilateral if three sides are given?

Answers

The length of a fourth side of a quadrilateral cannot be directly calculated from just the lengths of the other three sides. Additional information like the quadrilateral type, or types of angles within the quadrilateral, would be needed to calculate the length of the fourth side.

In mathematics, specifically geometry, the length of the fourth side of a quadrilateral (a shape with four sides) cannot be directly determined just by knowing the lengths of the three other sides. This is because a quadrilateral can be of multiple shapes such as squares, rectangles, parallelograms, trapezoids, etc., each having different properties.

However, if you have additional information like the types of angles within the quadrilateral or if it's a specific type of quadrilateral (rectangle, square, etc.), then you could possibly calculate the length of the fourth side.

For example, in a rectangle, opposite sides are equal so if you know three sides and know it's a rectangle, then the fourth side would be equal to the opposite side.

Without any additional information, there isn't a simple formula that can be used to directly calculate the length of the fourth side of any arbitrary quadrilateral.
