Answer:

6.45

Step-by-step explanation:

Every part is 0.01 bigger or smaller

You can find it out by subtraction and then division

6.5 - 6.4 = 0.1

0.1 : 10 = 0.01

There are 10 parts that's why you divide it by 10.

If there will be 2 parts you will divide by 2

Location of F on the given decimal number line is [tex]6.45[/tex] .

" Number line is defined as a straight line which represents the numbers on it with equal interval."

According to the question,

Given number line,

F is between two decimal numbers [tex]6.4[/tex] and [tex]6.5[/tex]

[tex]6.4[/tex] and [tex]6.5[/tex] divides into [tex]10[/tex] equal parts.

On the number line distance between [tex]6.4[/tex] and [tex]6.5[/tex] is equals to [tex]0.1[/tex]

Each part represents [tex]0.1 \over 10[/tex] distance which is equals to [tex]0.01[/tex].

F is on the [tex]5th[/tex] location.

On the number line distance of F from [tex]6.4[/tex] is [tex]0.01 \times 5 = 0.05[/tex]

Therefore, location of F  

[tex]= 6.4 + 0.05\\\\= 6.45[/tex]

Hence, location of F on the given decimal number line is [tex]6.45[/tex] .

Step-by-step explanation:

hey

[tex]4\frac{1}{6} +a=5\frac{2}{3}[/tex] is the equation that has a=[tex]1\frac{1}{2}[/tex] as its solution.

Two or more expressions with an Equal sign is called as Equation.

we need to find the equation which gives a=[tex]1\frac{1}{2}[/tex]

Convert the mixed fraction to the improper fraction

a=3/2

[tex]4\frac{1}{6} +a=5\frac{2}{3}[/tex]

Convert the mixed fraction to the improper fraction

25/6+a=17/3

Now take the variable on one side and constants on other sides

a=17/3-25/6

LCM of 3 and 6 is 6

a=34-25/6

a=9/6

The numerator and denominator are multiples of 3.

a=3/2

Hence, [tex]4\frac{1}{6} +a=5\frac{2}{3}[/tex] is the equation that has a=[tex]1\frac{1}{2}[/tex] as its solution.

Step-by-step explanation:

When you have a question like this, just think of it as a multiplication chart. 6 x 3 is 18 so you have 18 brownies.

Adriana can have 18 brownies.

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

Adrianna needs to cut a pan of brownies into pieces.

She cuts 6 even columns and 3 even rows into the pan.

That means,

Adriana cuts,

= 6 x 3

= 18 even parts of brownies.

CE = 36

Step-by-step explanation:

The opposite sides of a parallelogram are congruent , then

AS = CE , substitute values

2x + 10 = x + 23 ( subtract x from both sides )

x + 10 = 23 ( subtract 10 from both sides )

x = 13

Then

CE = x + 23 = 13 + 23 = 36
