Answer:
Hello! answer: 20
Step-by-step explanation:
circumference is just diameter × pi so If we do circumference ÷ pi we will get our diameter so
125.6 ÷ 3.14 = 40 But remember diameter is just twice the radius so all we have to do is divide by 2 to get our radius so
40 ÷ 2 = 20 So 20 is the radius Hope this helps!
Answer:
the answer is 20 feet
Step-by-step explanation:
divide the circumference by 3.14 gives you the diameter then divide the diameter by 2 to get the radius.

Answer:
Okay so, first put a dot on the number three. Next, go down one and over two from that spot (2, 2) and so on.
Step-by-step explanation:
Answer and step-by-step explanation:
Here, we are given a linear equation, meaning that the graph is going to be a straight line. Firstly, we must identify the slope and the y-intercept of the line.
y = -1/2x + 3
The -1/2x is our slope, and the 3 is our y-intercept. So, let's plot the coordinate (0, 3) because that is the y-intercept. Lastly, we must find how steep the line is, and what direction it goes to. As you can see, it is negative, so that means that the slope will go from the top left to the bottom right. And, the slope is -1/2, which means that for every time you go to right two, you will also go down one. Hope this helps!

Find the length of side x in simplest radical form with a rational denominator.
60°
V3
30°
X
Answer:
4√3/3
Step-by-step explanation:
Find the diagram attached below
Considering angle 60°
Opposite side = 2
Hypotenuse = x
Using the SOH CAH TOA identity
sin theta = opposite/hypotenuse
sin 60 = 2/x
x = 2/sin60
x = 2/(√3/2)
x = 2 * 2/√3
x = 4/√3
Rationalize
x = 4/√3 * √3/√3
x = 4√3/3
Hence the value of x in its simplest form is x = 4√3/3

Answer:
Perimeter = 25
Step-by-step explanation:
J(-2, 5)
K(1, 1)
L(1, -1)
M(-5, -4)
N(-5, 1)
Formula for distance between 2 coordinates is;
d = √((x_2 - x_1)² + (y_2 - y_1)²)
Thus;
JK = √((1 - (-2))² + (1 - 5)²)
JK = √25
JK = 5
KL = √((1 - 1)² + (-4 - 1)²)
KL = √25
KL = 5
LM = √((-5 - (-1))² + (-4 - (-1))²)
LM = 5
MN = √((-5 - (-5))² + (1 - (-4))²)
MN = 5
JN = √((-5 - (-2))² + (1 - 5))²)
JN = 5
Thus;
Perimeter = 5 + 5 + 5 + 5 + 5
Perimeter = 25
Which expression is not equal to the expression shown?
Answer:
[tex]3^{-3}[/tex] ÷ [tex]3^{4}[/tex]
Step-by-step explanation:
When pulged into a calculator:
[tex]3^{3}[/tex] ÷ [tex]3^{-4}[/tex] = 2187
When your options are pulged in you get this:
[tex]3^{-3}[/tex] ÷ [tex]3^{4}[/tex] = [tex]\frac{1}{2187}[/tex]
[tex]3^{3}[/tex] · [tex]3^{4}[/tex] = 2187
[tex]3^{7}[/tex] ÷ [tex]3^0[/tex] = 2187
3 · [tex]3^6[/tex] = 2187
because [tex]3^{-3}[/tex] ÷ [tex]3^{4}[/tex] doesn't equal 2187 that is your answer.

What is the slope of a line that passes through the points open parentheses short dash 1 comma 9 close parentheses and open parentheses 3 comma 6 close parentheses? a.) 10 over 3 b.) 3 over 10 c.) short dash 3 over 4 d.) short dash 4 over 3
Answer:
-3/4
Step-by-step explanation:
The answer will be option c which is short dash 3 over 4.
What is the slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.
Given points are:(1,9) and (3,6)
The slope of the line will be calculated as:-
y = mx + c
9 = m+c
6 = 3m+c
By solving the above linear equations we will get the value of m which will be our slope.
m = -3/2
Hence the answer will be option c which is short dash 3 over 4.

Step-by-step explanation:
A distribution center makes deliveries to food stores on a weekly basis. On the average, 50 stores are served daily. A typical store places an order for 10,000 lb of various products. 4 store orders can be placed on a delivery truck. Trucks are loaded in 5 hours. The distribution center operates an 8 hour shift. How many truck doors are needed?
Answer:
3 doors needed
Step-by-step explanation:
The computation of the no of trucks doors that are needed is shown below:
= serve daily ÷ no of store orders ÷ no of store orders
= 50 ÷ 4 ÷ 4
= 3 doors needed
First we divided the serve daily from the no of store orders and then the value that comes so it would be divided by no of store orders again so that the no of truck doors could come
