how to solve 6r - 1 + 6r =11

Answers

Answer:

r = 1

Step-by-step explanation:

The equation is,

→ 6r - 1 + 6r = 11

Now the value of r will be,

→ 6r - 1 + 6r = 11

→ 12r = 11 + 1

→ r = 12/12

→ [ r = 1 ]

Hence, the value of r is 1.

Answer:

The answer is 1 r is equal to 1

Answer:

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

the area of the five squares is 1289.09 square units

the perimeter is 194.6 units

Jacinta says that the product of a rational number and an irrational number is always irrational. Explain her error.

Answers

if u multiply an irrational number by 0 the result will be 0 which is a rational number. Except this case, other times will result with irrationals.

Jacinta says that the product of a rational number and an irrational number is always irrational her claim is wrong.

What is a rational number?

A rational number is one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.

Irrational numbers are all real numbers that are not rational numbers in mathematics. Irrational numbers, on the other hand, cannot be stated as the ratio of two integers. Decimal notation is the term used to describe the method of representing numbers in the decimal system.

Given that Jacinta says that the product of a rational number and an irrational number is always irrational.

Her statement is incorrect because if 0 a rational number is multiplied with the π which is irrational then the result will be 0 which is rational.

Therefore, Jacinta's claim is wrong.

Write an equation that expresses the relationship. Then solve the equation for u. B varies directly as the cube of t and inversely as u

Answers

Answer:

Below

Step-by-step explanation:

B varies directly with the cube of t so:

● B = t^3

B varies inversly as u

● B = 1/u

Let's solve the equation for u:

B= 1/u = t^3

● B= 1/u

Switch u and B

● u = 1/B = 1/t^3

If u is 1 then b and t are also 1.

Chloe needs to swim a total of 9 miles this week. So far this week , she swam 5 5/8 miles. Use the equation 5 5/8 + m =9 to find out how many more miles Chloe needs to swim.

Answers

Alright, so all we have to do here is solve the equation!

5 5/8 + m = 9

m = 9 - 5 5/8

Now is the tricky part - doing the subtraction! Let's change 9 to 8 8/8 (which is still equal to 9).

m = 8 8/8 - 5 5/8

Then we can subtract fairly easily!

m = (8 - 5) + (8/8 - 5/8)

m = 3 3/8 miles

Step-by-step explanation:

So Weight is out of the question since you do not need to weigh anything

Area is the inside of the picture so that is also out

It is either primeter or volume

Volume is used to find the surface of an object, it takes up. It is used for 3-d objects, since this is not a 3-d piece it is not that.

It is the primeter since you will need to find out the side legnths to find out what frame will work.
