ok what is the question
the diameter of a drum circle is 12 feet. what is the area of the drum
Answer:
37.68
Step-by-step explanation:
3.14 * 12 or 2(6 *3.14)
6 is the radius so you multiply by 2 and get 12. Multiply 12 by 3.14 to get 37.68

Hey there!
4a + 3b + 2a
=> 4a + 3b + 2a
=> 4a + 2a - 3b
=> 6a - 3b
Therefore, 4a + 3b + 2a = 6a - 3b

Explain how you would go about graphing this equation? What would be your first step and how would you go from there? Y=4x+6 *
Step-by-step explanation:
First I would look at the y intercept. In a linear equation, y = mx + b, b is the y-intercept and m is the slope. This means that (0,6) is a point on the line since at a y-intercept, the x value is 0. First you should plot this point.
Next, the slope is 4, meaning that for every 1 unit to the right, the line rises 4 units. You can count 1 to the right and 4 up from the y-intercept, which gives you (1,10), a second point on the line. After this, you can connect the two points and there you go, you have a graph!

What is the value of x in the equation 8x – 2y = 48, when y = 4?.
Step-by-step explanation:
Substitute the value of y into the equation;
[tex]8x-2(4)=48[/tex]
Find the value of x.
Multiply;
[tex]8x-8=48[/tex]
Add 8 to each side;
[tex]8x=56[/tex]
Divide each side by 8;
[tex]x=7[/tex]
Answer:
x = 7
Step-by-step explanation:
Given:
y = 4Step-1: Substitute the y-variable in the equation (8x – 2y = 48)
⇒ 8x - 2y = 48⇒ 8x - 2(4) = 48Step-2: Simplify the L.H.S
⇒ 8x - 2(4) = 48⇒ 8x - 8 = 48Step-3: Add 8 both sides
⇒ 8x - 8 = 48⇒ 8x - 8 + 8 = 48 + 8⇒ 8x = 56Step-4: Divide 8 both sides
⇒ 8x = 56⇒ 8x/8 = 56/8⇒ x = 7An elephant weighs 8.8 x 103 kg. A small dog weighs 4 kg. How many
4
times heavier is the elephant than the dog?
A 22,000 times heavier
B. 2,200 times heavier
C. 220 times heavier
D. 22 times heavier
Answer:
I'd have to go with C.
Step-by-step explanation:
8.8 x 103=
906.4
And if you have to times it by 4, than its most likely 220
220 x 4=
880

Ivan must choose a number between 55 and 101 that is a multiple of 4, 5, and 8. Write all the numbers that he could choose. If there is more than one number, separate them with commas.
Solution:
1. Since the numbers must be divisible by 2 even numbers, all odd numbers are ruled out because odd numbers are not divisible with even numbers.
In this case, the numbers that are possible are:
56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 1002. Since the numbers must be divisible by 5, it rules out a few more numbers.
In this case, the remaining numbers are:
60, 70, 80, 90, 100We can clearly tell that the only number that is divisible by 8, 5, and 4 is 80.
Thus, 80 is the number.
What are the values of w and x? NO LINKS
Step-by-step explanation:
Since angles opposite congruent sides in a triangle are congruent, w=67.
Now, since the sum of the measures of the interior angles of a triangle is 180 degrees, x=180-67-67=46

A phone company offers two monthly plans. Plan A costs $20 plus an additional $0.11 for each minute of calls. Plan B costs $14 plus an additional $0.13 for each minute of calls.
For what amount of calling do the two plans cost the same? ____Answer
What is the cost when the two plans cost the same?
$_____answer
Answer:
a. 300 minutes.
b. $53
explanation:
make equations from given information.
consider each minute as "n"equation 1 from plan A :
20 + 0.11(n)
equation 2 from plan B :
14 + 0.13(n)
Solve them simultaneously,
14 + 0.13(n) = 20 + 0.11(n)
0.13(n) - 0.11(n) = 20 - 14
0.02(n) = 6
n = 300
insert n = 300 in any of the equation, to find cost.
14 + 0.13(n)
14 + 0.13(300)
$53
Sum of the angles of a polygon with 10 sides is -------
Answer:
1440°
Step-by-step explanation:
Each exterior angle of a 10 sided regular polygon =360/10=36°
Each interior angle = 180°-36° =144°.
Sum of all interior angles = 144°×10. = 1440°.

Eve needs 2/9 ounces of paint to make a flower. how much paint does she need for 3 flowers?
[tex]\begin{array}{ccll} paint&flowers\\ \cline{1-2} \frac{2}{9} & 1\\ x& 3 \end{array} \implies \cfrac{~~ \frac{2}{9}~~}{x}=\cfrac{1}{3}\implies \cfrac{2}{9x}=\cfrac{1}{3} \\\\\\ 6=9x\implies \cfrac{6}{9}=x\implies \cfrac{2}{3}=x[/tex]
What is the y-intercept for the equation y = 15x + 2?
Answer:
The y-intercept is +2
using y=mx+b we can tell anything added is the intercept.
+2
Step-by-step explanation:
We know the standard equation is
y = mx + c
where m is the slope and c is the y-intercept.
By Comparing the given equation with the standard equation we get,
y-intercept = +2

What is the y coordinate of the vertex of y = − x^2 − 6x + 1
Answer:
y = 10Step-by-step explanation:
The vertex coordinates of f(x) = ax² + bx + c is (h, k)
where: [tex]h=\dfrac{-b}{2a}\ ,\qquad k=f(h)[/tex]
f(x) = - x² - 6x + 1 ⇒ a = -1 b = -6
So:
[tex]h=\dfrac{-(-6)}{2(-1)}=\dfrac6{-2}=-3\\\\y=f(h)=-(-3)^2-6(-3)+1=-9+18+1=10[/tex]

Answer:
A.15
Step-by-step explanation:
These two triangles are congruent triangles. This means that the side measurements can be found through a single multiplicative number.
All you have to do is divide 49 by 23 and get 2.130434783. You need that number to be specific
Next you want to multiply that number by the side length that corresponds to the length you are trying to find. In this case that is 7.
7 x 2.130434783=14.9
14.9 rounds to 15
help !!! what are the zeros of the function?
f(x)=x^2-5x
Answer:
f(x) = x² -5x factor this function
x(x-5) = 0 ----> either x =0 , or x -5 =0 then x =5
the two values of x make f(x) =0 are 0 and 5
we can check by substituting these two values
at x = 0 ----> f(0) = 0² - 5 * 0 ---> f(x) =0
at x =5 ----> f(5)= 5² -5 * 5 ---> f(x) =0
