You will add them all together, then multiply the sum by 6.
713/6 = 118.833333
this rounded to the nearest hundredth
$118.83 per month

Identify each pair of angles as corresponding, Alternate interior, alternate exterior, or consecutive interior and solve for X

-BARSIC- [3]

Answer:

Step-by-step explanation:

19). Angles measuring 90° and (21x + 6)° are Alternate exterior angles.

Therefore, 21x + 6 = 90

2x = 90 - 6

2x = 84

x = 42

21). Angles measuring 60° and (8x - 4)° are Alternate interior angles,

8x - 4 = 60

8x = 60 + 4

x = $\frac{64}{8}$

x = 8

23). Since, angles measuring (-1 + 14x)° and (12x + 17)° are Alternate exterior angles

Therefore, (-1 + 14x) = (12x + 17)

14x - 12x = 17 + 1

2x = 18

x = 9

25). Both the angles (x + 96)° and (x + 96)° are consecutive interior angles.

Therefore, (x + 96)° + (x + 96)° = 180° [Property of consecutive interior angles]

2x + 192 = 180

2x = 180 - 192

2x = -12

x = -6

Now measure of (x + 96)° = -6 + 96

= 90°

26). Both the angles (20x + 5)° and (24x - 1)° are consecutive interior angles.

Therefore, (20x + 5)° + (24x - 1)° = 180°

44x + 4 = 180

44x = 176

x = 4

I need help I tried to do this question with one C and with two C

OverLord2011 [107]

There are two c's. You must pay attention to capitalization, there's a lowercase c and an uppercase C which represent two different variables. Also, the W is capitalized which could make your answer incorrect if you don't use the same notation.

Solving for small c..

$C = \frac{Wtc}{1,000} \\\\ 1,000C = Wtc \\\\\frac{1,000C}{Wt}= c$

So it's the answer shown in the picture, but it should be a capital W instead of a lowercase w.

Let 3x^2+kx+4. determine all values of k such that the quadratic equation f(x) =0 has one real root

user100 [1]

//I'll use the discriminant rule for this.
b^2 - 4ac = 0 when one real root

Therefore, k^2 - 4*3*4= 0
k^2 = 48
k= +-4√3

Your sock drawer has two white socks, four brown socks, and two black socks. You randomly pick a sock and put it on your left fo

zmey [24]

Answer:

The probability of this occurring is 1/7

Step-by-step explanation:

Okay, here is a probability question.

From the question, we can identify the following;

Total number of socks = 2 + 4 + 2 = 8 socks

Since we are not given the order in which the socks was worn, we can assume any order.

Let’s say the right leg socks was worn first.

From the question, the socks on the right leg is a brown one.

So now let’s calculate the probability of selecting a brown socks out of the mix

That would be ;

number of brown socks/ total number of socks = 4/8 = 1/2

Now, for the left foot, we are having white sock here.

Kindly recall that since we already have a sock on the right foot, we have 7 socks left to pick from.

Now we need the probability of picking a white sock from the total 7. That would be ; 2/7

So the probability of both action occurring is simply the product of both probabilities and that is ;

1/2 * 2/7 = 1/7
