Answer:
Yes
Step-by-step explanation:
The definition of a rational number is a number that can be represented as a fraction. Since 56/7 is a fraction it must be a rational number. An irrational number is a number that cannot be represented as a fraction because it never ends and repeats without a pattern forever. An example of this is pi because pi can never exactly be represented as a fraction.
Answer:
The dashed hypotenuse measures: 3,205.13 ft.
Step-by-step explanation:
. B (Plane is here)
. .
. .
A . . . . . . . C
BC = 500 ft
Angle (Ф) between AB and AC = 9 degrees
So,
Sin(Ф) = BC/AB
Since we need to know how much hypotenuse AB measures, Let's isolate it from the equation:
AB = BC / Sin (Ф)
AB = 500 ft. / Sin (9)
AB = 500 ft./ 0.156
AB = 3,205.13 ft.
Answer:
x > −2
Step-by-step explanation:
You need to isolate the variable. You can do this by first subtracting 3/2 from both sides of the inequality sign.
You will get -x/2 < 2/2.
Next, since x is being divided by -2, you will multiply it by -2 to undo it. Do this to both sides.
Note that when multiplying or dividing by a negative you will flip the inequality sign. '<' becomes '>' and '>' becomes '<'.
You will get x > -2.
Hey, there! For this question, we can just start by plugging in the known values. 
can be rewritten as 
.
Combine like terms: 
If you add x to 
, x will become 
, which means that x/2 + x = 3/2x.
--> 
If you rearrange this, then your answer will be option b. Hope this helps.
Answer:
question 20 ) 19.1 feet
question 21) 24 clips
Step-by-step explanation:
<h2><u>Question 20:</u></h2><h3><u>Circumference of a circle </u></h3>
formula:
therefore we can find the radius (r) , also include the circumference of 60 feet.
where 
2 * 3.14 * r = 60
r = 
r = 9.554....
<h3>to find the diameter we can use the formula :</h3>
<em>diameter = radius * 2</em>
diameter = 9.554 * 2
diameter = 19.108
to 3 sf
<h3><u>diameter = 19.1 feet </u></h3>
<u />
<h2><u>Question 21</u></h2>
large binder clips each cost $ 1.50
amount for purchases is $ 36.00
therefore the number of clips bought can be regarded as (x)
the formula would be :
1.50 * x = 36
x = 36/1.5
<u>x = 24</u>
<u></u>
<h3><u>hence the mom bought 24 binder clips</u></h3>
