I Need Help With Geometry

Answers

Answer 1

Answer:

It 12

Step-by-step explanation:

This is because the scale factor between the triangles is 1.75, so I divide 21 by 1.75 and got 12

Hope this helped

Answer 2

We first have to find 2 pairs of sides that proportional.

35/20=42/24=7/4

and 21/b should be 7/4 as well because if we want the triangles to be similar the sides should be in proportion.

21/b=7/4

84=7b

b=12

Done!

Hope this helped, any questions about this just ask in the comments and I will answer.

What are integers?
Please give your best explanation and a simple example (worth 20 points)

Answers

ExplanationWhat is Integer?

Integer is a subset of Real Number. It can be broken into these following:

Positive IntegerZeroNegative Integer

Integer can be any whole numbers. Keep in mind that Integers cannot be fractions, decimal, approximate value, etc. Integers can only be something like 1,2,3,-1,-2,0.

Integers are like Natural or Counting Numbers except they have 0 and negative numbers.

Positive Integer

Positive Integers are basically a natural or counting number. It starts from 1 to any positive countable infinity. Here is the example of positive integer: 1,2,3,4,5,6,7,...

Zero

Zero is just a number 0. It is between the negative and positive. 0 is neither positive or negative but it is categorized as Zero.

Negative Integers

Negative Integers are opposite of Positive Integers. The opposite of plus is minus and the opposite of minus is plus. Negative Integers are less than both 0 and Positive Integers. Here is the example: -1,-2,-3,-4,-5,...

Integers are whole numbers with a positive or negative counterparts.

If that doesn't make sense let me make some examples

-4, 100, 9300 would be integers. Using my definition they all have negative or positive counterparts.

-2.3, 7.8888(etc.) 2/3 would not be integers. Even though -2.3 and 7.8888(etc.) have negative/ positive counterparts they are not whole numbers.

Hope that helped!

What equation represents the slope intercept form of the line below Y intercept =(0,-2) slope = 2/3

Answers

Answer: [tex]y = \frac{2}{3} x - 2[/tex]

Step-by-step explanation:

The slope intercept form is y = mx + b

Where m is our slope and b is our y-intercept

We're given a slope of 2/3

We're given a y-intercept of -2

Substituting into y = mx + b gives

[tex]y = \frac{2}{3} x - 2[/tex]

Answer:

y = (2/3)x - 2

Step-by-step explanation:

Use the slope-intercept form y = mx + b.  Here b = -2 and m = 2/3.  Making these replacements, we get:

y = (2/3)x - 2

Is the equation y=3x in slope-intercept form? Explain. The equation y=3x in slope-intercept form. Question 2 The slope is and the y-intercept is a .

Answers

Given:

The given equation is

[tex]y=3x[/tex]

To find:

Whether the given equation is in the slope intercept form or not, then find the slope and y-intercept.

Solution:

Slope intercept form of a linear function is

[tex]y=mx+b[/tex]            ...(i)

Where, m is the slope and b is the y-intercept.

We have,

[tex]y=3x[/tex]    

It can be written as

[tex]y=3x+0[/tex]               ...(ii)

On comparing (i) and (ii), we get

[tex]m=3,b=0[/tex]

Therefore, the given equations is in slope intercept form. The slope of the line is 3 and the y-intercept is 0.

A recipe for sparkling grape jucie calle for 1 1/2 quarts of sparkling water and 3/4 quart of grape jucie. How much sparkling water would you need to mix with 9 quarts of grape jucie?

Answers

Answer: 18 quarts of sparkling water

Step-by-step explanation:

From the question, we are informed that a recipe for sparkling grape jucie calle for 1 1/2 quarts of sparkling water and 3/4 quart of grape jucie.

When there's an increase in the quarts of grape juice to 9, it simply means that the former grape juice has been multiplied 12 times (9 ÷ 3/4 = 9 × 4/3 = 12).

Therefore, we would also multiplybl the sparkling water given by 12 to get the new quantity needed. This will be:

= 1 1/2 × 12

= 3/2 × 12

= 18 quarts of sparkling water

Which of the following two-dimensional shapes can be rotated to create a sphere?

A. Triangle
B. Square
C. Circle
D. Ellipse

please give an explanation and not just a letter or answer. Thank you.

Answers

The answer is C. circle because a sphere is formed by rotating a circle by any of its diameters

The shape that can be rotated to create a sphere is the circle (option C).

A sphere is a three-dimensional object with all points equidistant from its center. When a circle is rotated about its center axis, it creates a three-dimensional shape that perfectly matches the definition of a sphere.

Let's consider the other options and why they cannot be rotated to form a sphere:

A. Triangle: A triangle is a two-dimensional shape with straight sides. Rotating a triangle around any axis would not result in a three-dimensional shape with all points equidistant from its center, which is the defining characteristic of a sphere.

B. Square: Similarly, a square is a two-dimensional shape with straight sides. Rotating a square around any axis would not create a sphere, as it would still retain its flat, planar nature.

D. Ellipse: An ellipse is a two-dimensional shape resembling a squashed or stretched circle. Rotating an ellipse would not result in a sphere, as it would still retain its elliptical shape.

Therefore, the shape that can be rotated to create a sphere is the circle (option C) due to its symmetrical and curved nature.
