Answer:

10.5

Step-by-step explanation:

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.

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

Answer:

you had to multiply i think

Step-by-step explanation:

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:

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 .

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 :)

18 is the answer

Step-by-step explanation:

x=11+7

x=18

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°

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

Answer:

I think it is 68cm

Step-by-step explanation:

The correct graph that shows this rotation is shown in Option 3.

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.
