1.) 5, 10,12

2.) 6,5,3

3.) 3, 4, 5

4.) 6, 8,10



*Pls explain all ill give you brainliest or w.e its called*

Answers

3.) 3, 4, 5
&
4.) 6, 8, 10
Those two are right triangles because when you add the squares of the first two it should give you the square root of the third number

a^2 + b^2 = c^2

So
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25

6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100

Therefore they are right triangles

But 1 & 2 aren’t right triangles because when you add the squares of the first two number, it doesn’t equal to the square root of the third number.

A ladybug and ant move at constant speeds. The diagrams with tick marks show their positions at different times. Each tick mark represents 1 centimeter. Lines u and v also show the positions of the two bugs. Which line shows the ladybug’s movement?

Answers

Answer:

Line u shows the movement of the ladybug. Because line v goes farther than line u

Step-by-step explanation:

Because line v goes farther than line u

The ladybug's motion is depicted in line u. Because line v is moving farther than line u.

What is Speed?

The amount of the shift in approach per unit of time or the size of the displacement over time for an object can be used to describe speed, which would be a scalar quantity in everyday language and kinematics.

The maximum speed that can be maintained when a period grows closer to zero is the starting speed.

By dividing the object's distance traveled by the duration of the interval, the mean pace of the object for the given period is calculated. Speed and velocity are not always the same thing.

The line u and v show the position of the two bugs, but the line that shows the ladybug's movement is line u because line v is moving farther than line u.

If the area of a triangle is 100 in^2, and the height is 10in, find the length of the base in inches.
Round to the nearest inch if applicable.

Answers

Answer:

Area of a triangle is 100 in²

Height of triangle is 10 in .

we have been asked to find the length of its base .

Formula Used to Find length of its base

☯[tex] \bf\: Area \: of \: triangle \: = \dfrac{1}{2} \times base \: \times height \: [/tex]

Put the given value we obtain

[tex] \rm \implies \: 100 = \dfrac{1}{2} \times base \: \times 10 \\ \\ \rm \implies \: 100 = \dfrac{1}{ \cancel2} \times base \: \times \cancel{10} \\ \\ \rm \implies \: 100 = base \: \times 5 \\ \\ \rm \implies \: base \: = \dfrac{100}{5} \\ \\ \rm \implies \: base \: = \cancel\dfrac{100}{5} \\ \\ \rm \implies \: base \: = 20 \: inch[/tex]

So, the length of its base is 20 inch .

The base length of the triangle with the given values of area and length of height to the nearest inch 20in.

What is a triangle?

A triangle is a two-dimensional shape with three edges and three vertices.

The area of a triangle is expressed as;

A = (1/2) × base × height

Given the data in the question;

Area of the triangle A = 100in²Length of Height = 10inLength of Base = ?

We substitute our given values into the expression above.

A = (1/2) × base × height

100in² = (1/2) × Base × 10in

100in² = 0.5 × 10in × Base

100in² = 5in × Base

Base = 100in² / 5in

Base = 20in

Therefore, the base length of the triangle with the given values of area and length of height to the nearest inch 20in.

A bike costs $650.00. Then it is marked down 35%
What is the final sale price of the bike?
PLEASE ANSWER QUICKLY

Answers

Answer:

$422.50

Step-by-step explanation:

If the bike is marked down by 35% then the final sale price will be 65% of the original price (since 100% - 35% = 65%).

Convert 65% into a decimal:  65% = 65/100 = 0.65

Therefore, 65% of $650 = 0.65 × 650 = $422.50

We need first mark downed amount

A population of five families is to be sampled. The incomes of the five families (in thousands of dollars) are: Family Income ($000) A 12 B 23 C 18 D 7 E 16 a. Find the population mean income of the five families. 2 point

The population mean income of the five families is their average income

The population mean income of the five families is #15.2

How to determine the population mean?

The income of the five families in a thousand dollars is given as:

A 12 B 23 C 18 D 7 E 16

The population mean is then calculated as:

[tex]\mu = \frac{\sum x}n[/tex]

So, we have:

[tex]\mu = \frac{12 + 23 + 18 + 7 + 16}5[/tex]

Evaluate the sum

• Can you list down similarities of your experience with your circle of friends?

A recent study published in Nature Communications says the reason for this likeness is that best friends actually have similar — or sometimes identical — brain activity..

Yup , your closest friends "get you" because it's like their basically looking in the mirror..

Friends and tend to have certain characteristics in common , Such as Age, Education and even intelligence — and yet , Research has long suggested that personality isn't one of these commonalities..

Some scientific research has shown how you're likely to be attracted to people who share similar facial characteristics as you.

One theory for this is that we associate people who look like us with our parents, and thus have more positive feelings towards their features.

Similarities are also important for friendships.

let f(x)=3-3x+5x^2.calculate the following.
f(a)=
f(a+h)=
f(a+h)-f(a)/h= for h≠0

Answers

Answer & step-by-step explanation:

[tex]f(a)[/tex] is simply calculating by replacing a in lieu of x

[tex]f(a) = 3-3a+5a^2[/tex]

Same difference for [tex]f(a+h)[/tex], just be careful with products and squares:

[tex]f(a+h) = 3-3(a+h)+5(a+h)^2 = 3-3a-3h+5a^2+10ah+5h^2 = 3-3a+5a^2 -3h+10ah+5h^2[/tex]

In the last step i just reorganized terms so that everything containing h was at the end.

Finally, for the incremental ratio, writing it as 1/h for the sake of font sizes:[tex]\frac{f(a+h)-f(a)}h = \frac1h[(3-3a+5a^2-3h+10ah+5h^2)-(3-3a+5a^2)]=\\\frac1h(-3h+10ah+5h^2) = 10a-3 +5h[/tex]

The perimeter of rectangle is 36 the length is 3 more than two times the width

Answers

Answer:

The width of the rectangle is equal to 5 and the length is equal to 13

Step-by-step explanation:

Perimeter of rectangle = (Length + Width) ×2

Perimeter of rectangle = (13 + 5) ×2

Perimeter of rectangle = 36

The length of the rectangle is 13, which is 3 more than two times the width, if the width is 5

5 (Width) ×2 = 10

10 +3 = 13 (Length)

In an isosceles triangle (a triangle where two of the three sides called legs are equal), the legs
are 1 unit less than twice the length of the base. If the length of the base of the triangle is
represented by x, create an expression that represents the perimeter of the triangle.

X+3y - 2z=2
3x+2y+z=13
-2x+3y - 3z= -5

Answers

Answer:

{x,y,z}={1,3,4}

Step-by-step explanation:

System of Linear Equations given :

 [1]    x + 3y - 2z = 2

  [2]    3x + 2y + z = 13

  [3]    -2x + 3y - 3z = -5

Solve by Substitution :

// Solve equation [2] for the variable  z

 [2]    z = -3x - 2y + 13

// Plug this in for variable  z  in equation [1]

  [1]    x + 3y - 2•(-3x-2y+13) = 2

  [1]    7x + 7y = 28

// Plug this in for variable  z  in equation [3]

  [3]    -2x + 3y - 3•(-3x-2y+13) = -5

  [3]    7x + 9y = 34

// Solve equation [3] for the variable  y

 [3]    9y = -7x + 34

 [3]    y = -7x/9 + 34/9

// Plug this in for variable  y  in equation [1]

  [1]    7x + 7•(-7x/9+34/9) = 28

  [1]    14x/9 = 14/9

  [1]    14x = 14

// Solve equation [1] for the variable  x

  [1]    14x = 14

  [1]    x = 1

// By now we know this much :

   x = 1

   y = -7x/9+34/9

   z = -3x-2y+13

// Use the  x  value to solve for  y

   y = -(7/9)(1)+34/9 = 3

// Use the  x  and  y  values to solve for  z

 z = -3(1)-2(3)+13 = 4

Solution :

{x,y,z} = {1,3,4}
