Answers

Answer 1

Answer:

3,300 sq meters

Step-by-step explanation:

Base : 30 x 30 = 900

Side Triangle 1 : 40 x 30 / 2 = 600

Side Triangle 2 : 40 x 30 / 2 = 600

Side Triangle 3 : 40 x 30 / 2 = 600

Side Triangle 4 : 40 x 30 / 2 = 600

900 + 600 + 600 + 600 + 600 = 3,330 sq meters

Answer 2

Find the distance from Alanah's house to Mia's house. Round the answer to the nearest tenth. (Please explain how you get the answer I don't know how to do it) Will give Brainliest

Answers

Answer:

10

Step-by-step explanation:

This has to do with the Pythagorean thereon.

a^2 + b^2 = c^2.

With that set we need to find what a and b are.

a = 8 (one leg)

b = 6 (the other leg)

so

8^2 + 6^2 =

64 + 36 =

(the longest side is called the hypotenuse)

100= c^2

c=10

Hope this helped:)!

What is the distance formula between two points?

The distance formula between two points forming a line segment (x₁, y₁) and (x₂, y₂) is,

[tex]D = \sqrt{(x_2 - x_1)^2 +(y_2 - y_1)^2}[/tex].

A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

A line segment is a subset of a line having two endpoints and these endpoints are represented by coordinate points.

From the graph, the location of Alanah is (2, 8), and the location of Mia

is (8, 16).

Therefore, The distance between their house is,

[tex]D = \sqrt{(8 - 2)^2 +(16 - 8)^2}[/tex].

[tex]D = \sqrt{36 +84}[/tex].

[tex]D = \sqrt{120}[/tex].

D = 2(√30) units.

Find the area...

Step-by-step explanation:

Okay, here we are given two different shapes. One being a rectangle, and the other being a triangle. We are trying to find the area of the two shapes combined and in order to do so here are the steps:

The area of a rectangle is as follows:

[tex]b*h=A[/tex]

The area of a triangle is as follows:

[tex]A= \frac{1}{2} b*h\\or \\A=\frac{b*h}{2}[/tex]

Note: Notice how rectancgles have coensideing sides. Meaning that the opposite side of 9in will be 9 in and the opposite side of 6 in will be 6in.

Now lets solve the problem:

[tex]b*h =A\\6*9=54 sq inches\\A=\frac{1}{2} b*h\\A=\frac{1}{2} 6*2\\A=\frac{1}{2}(12)\\A=6 sq inches\\6+54=60 sq inches[/tex]

2.) Given: There are 30 students. 24 are wearing sneakers.

Work: We can figure this out by finding the exact percentage of sneaker-wearers in the class.

To find the percentage, you do 24/30. 24/30 is equal to 80%.


Answer: Joe is wrong. The percentage of students wearing sneakers is 80% and not 70%.


3.) Given: There are 40 people total. 2 women per 3 men.

Work: 2:3 women to men

If we multiply both by 10, we will get 50 people in total.

20:30 = 50

So we need to shrivel this down to 40 by taking out 5 on both sides of the ratio.

50 - 5 - 5 = 15:25 = 40

But the ratio need to be divisible by 2 because of the 2 women that are needed per 3 men. We can do this by moving over one human to the men’s side.

There are 14 women and 26 men. I didn’t use any of the strategies there listed because I don’t even remember what those are. I’m in grade 9. I would say that the ratio table works best because I just used ratios...


4.) Given: Find simplified fraction of silicon. 100%.

Work: Add all things up to find out the denominator for the fraction. They will equal 100.

This is the simplified form.
