What is the location of F on the decimal number line below?
Write your answer as a decimal
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] .
What is number line?" 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] .

Angles a and b are ertical angles the measure of angle a is 8x+1 and angle b is 21-2x find each angle measure
Answer:
Angle a = 17°
Angle b = 17°
Step-by-step explanation:
Angles a and b are vertical angles the measure of angle a is 8x+1 and angle b is 21-2x find each angle measure
Vertical angles are angles that are equal to each other
Step 1
We find x
a = b
Hence,
8x+1 = 21-2x
Collect like terms
8x + 2x = 21 - 1
10x = 20
x = 20/10
x = 2
Step 2
We find each angle
Angle a
8x+1
x = 2
Angle a = 8(2) + 1
= 17°
Angle b
21-2x
x = 2
21 - (2 × 2)
= 21 - 4
= 17°
Therefore:
Angle a = 17°
Angle b = 17°
