Find the CIRCUMFERENCE of a circle with a RADIUS of 13mm. Use 3.14 for the value of pi.
Answer:
Circumference = 81.64
Step-by-step explanation:
The formula for finding circumference is C = pi(d). Since you don't have the diameter, but you do have the radius (which is half of the diameter), you will multiply 13 by 2, or 13 x 2. 13 x 2 = 26. So, the diameter is 26.
Fill in what you know: C = 3.14(26)
Now, all you have to do is multiply 3.14 and 26, which equals 81.64.
Hope this helps! :)

Answer: 112in^2
Step-by-step explanation:
area of rectangle is
10 x 10 = 100 in ^2
then area of the triangle
h x b / 2 = 12 in^2
so 100 + 12 = 112 in^2
Carla's library account showed that she owed $4.00 in late fees. She made a payment of $7.00. She then lost a library book and was assessed a $12.00 fine. If Carla then makes a payment of $20, what is her balance after the payment?
Answer:
$9
Step-by-step explanation:
ok so this is what she owes- **i'm 'separating' them to make it easier**
$4 and $12 so let's add those together-
4+12=$16 so she owes 16 dollars in fines and late fees
and let's remember that she paid $7 for her late fee and assuming that she gets her $3 back she has $3 so far then for the 12 dollar fine she pays 20 dollars, and we're assuming that she gets back $6
she should have $9 left
good luck :)
**please let me know if this was incorrect/ not what you were looking for or both**

Answer:
k is constant of proportionality
Monday: k = 7.5
Tuesday: k = 2
Step-by-step explanation:
The equation for proportionality is y = kx
Take the first line of the table, plug it in and solve for k. Do that with at least 1 other row to be sure k is the same.
15 = (k)(2)
k = 7.5
——————
Same thing for this day. x is the horizontal, y is the vertical.
16 = (k)(8)
How many mg of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel? Which of the following equations could be used to solve this?
Answer:
3.29 milligrams of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel.
Step-by-step explanation:
To determine how many mg of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel, the following calculations must be performed:
50 + 0.62X = 78
0.62X = 78 - 50
0.62X = 28
X = 28 / 0.62
X = 45.16
100 - 45.16 = 54.84
54.84 = 4
45.16 = X
45.16 x 4 / 54.84 = X
180.64 / 54.84 = X
3.29 = X
Therefore, 3.29 milligrams of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel.
Answer:
C
Step-by-step explanation:

Answer:
<1 = 50
<2 = 40
<3 = 90
<4 = 90
<5 = 40
<6 = 50
<7 = 130
Step-by-step explanation:
<5 + <6 = 90
40 + <6 = 90
<6 = 50
<5 = <2 because of vertical angles
<2 = 40
<6 = <1 because of vertical angles
<1 = 50
<7 = <4 + <5
<7 = 90 + 40
<7 = 130
Answer:
Solution given:
<4=90°[vertically opposite angle]
<2=<5=40°[vertically opposite angle]
<3=90°[right angle]
again
<1+<2=90°[right angle]
<1=90°-40°=50°
<1=50°
again
<5=40°[given]
<6=<1=50°[vertically opposite angle]
<6=50°
again
<7=<4+<5=90°+40°=130°

The change in the average price of a gallon
of milk from 2011 to 2013 is shown in the
table below.
At the end of 2010, the price of a gallon of
milk was $3.47.
What was the price, in dollars, of a gallon of milk at the end of 2013?
Answer:
Price at the end of 2011 :
$3.47 - 0.57 = $2.90
Price at the end of 2012 :
$2.90 + $0.25 = $3.15
Price at the end of 2013 :
$3.15 - $0.08 = $3.07
So, at the end of 2013, the price of a gallon of milk was $3.07 .

Quadrilateral ABCD is rotated 90° about the origin. Select the graph that shows this rotation.
The correct graph that shows this rotation is shown in Option 3.
What is Translation?A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.
Given that;
Quadrilateral ABCD is rotated 90° about the origin.
Now, We know that;
Condition of 90° clockwise rotation: (x, y) becomes (y,-x)
Hence, For Option 1;
A = (- 2, - 2)
A' = (2, - 2)
Foe option 2;
A = (- 2, - 2)
A' = (2, 2)
Thus, This shows correct graph of rotation.

Answer:
C. (5-1), (5-2), (5-3), (5-4), (5-5), (5-6)
Step-by-step explanation:
So let's look at the choices and find which one has only one 3 (3's will be boldened for convenience).
A. (1-1), (2-2), (3-3), (4-4), (5-5), (6-6)
A has two three's, so it's out.
B. (1-3), (2-3), (3-1), (3-2), (3-4), (3-5), (3-6), (4-3), (5-3), (6-3)
B has 10 three's, so it's also out.
C. (5-1) (5-2) (5-3) (5-4) (5-5) (5-6)
C has 1 three, so it's correct. However I will still test D to make sure.
D. (1-6) (2-5) (3-4) (4-3) (5-2) (6-1)
D, like A, has two three's, so it's out.
With that information, we can deduce that C has the favorable outcomes for rolling exactly 1 three.
