Simplify the ratio:26:65

Answers

(26)/(25)

Divide both numerator and denominator by "13", and you get,

(2)/(5)

And thats your simplified answer

Final answer:

In order to simplify the ratio 26:65, we find the greatest common divisor of 26 and 65, which is 13. Dividing both numbers of the ratio by this divisor, the simplified ratio becomes 2:5.

Explanation:

To simplify the given ratio 26:65, we need to find the greatest common divisor (GCD) of the two numbers and divide each of them by this GCD. The GCD of 26 and 65 is 13. Hence, we divide both numbers of the ratio by 13.

26 ÷ 13 = 2

65 ÷ 13 = 5

Therefore, the simplified form of the ratio 26:65 is 2:5.

What is the value of k + 12, if k = 6

Answers

The value of the equation is A = 18

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = k + 12   be equation (1)

when k = 6

Substituting the value of k in the equation , we get

A = 6 + 12

A = 18

Therefore , the value of k is 18

Hence , the equation is A = 18

Quadratic graphs:y = x2 + 4x + 1

I need to work out the coordinates.
Help.

Answers

if x =1,
y= 1^2 +4(1) +1
=7
x=0, y=1

Answer:

Basically what you have to do to draw the graph is creating a bunch of points that are part of the equation

to do so, you assign different values to x and find the corresponding y

for example

x=0 0^2 +4*0 +1 = 1 therefore  y = 1

x=1 1^2+4*1 +1 = 6 therefore y= 6

and so on....

x=-1 y=-2

and as many as you need

this is valid...only if I have understood your question :-)

Step-by-step explanation:

Are they scaled copies or not? If so how do I find out?

Answers

1) Find the length of the diagonals of the greater rhombus

NJ=9 units

XY=6 units

Find the the ratio

NJ/XY=9/6-------> 3/2

2) Find the length of the diagonals of the smaller rhombus

HS=6 units

ZC=4 units

Find the the ratio

HS/ZC=6/4-------> 3/2

so

NJ/XY=HS/ZC--------> the rhombus are similar

the scale factor is equal to ------> 3/2=1.5

measure greater rhombus =scale factor*measure smaller rhombus

measure greater rhombus =1.5*measure smaller rhombus

measure smaller rhombus=(measure greater rhombus/1.5)

therefore

the answer is

Yes , they are a scaled copies and the scale factor is equal to 1.5
