I NEED HELP HURRY PLEASE! Find the value of x.

Mathematics
1 answer:
REY [17]3 years ago
6 0

Answer:

C. x = 7

Step-by-step explanation:

All angles of a square add up to 360° and there are 4 angles in every square. Since all angles of a square are 360/4 = 90, Then 12x + 6 = 90.

12x + 6 - 6 = 90 - 6

12x = 84

12x/12 = 84/12

x = 7

Find an equation for the line with an x-intercept of 4 and y-intercept of -2
Bumek [7]

Answer:

Step-by-step explanation:

The x-intercept exists when y = 0; the coordinate that results from our x-intercept is (4, 0).

The y-intercept exists when x = 0; the coordinate that results from our y-intercept is (0, -2).

We can use these 2 coordinates to find the slope of the line we need to write:

m=\frac{-2-0}{0-4}=\frac{1}{2}

Now we can use that slope along with one of our points to write the equation of the line.  I am going to use the point-slope form, then we will solve it for y to put it into slope-intercept.  Let's use the coordinate (4, 0).  Keep in mind that regardless of which point we choose to use to write our equation, we will get the same equation.

y - 0 = 1/2(x - 4) and

y = 1/2x - 2

That's your equation!

Alright to the nearest 100th now
kirill [66]

Answer:

28.26

Step-by-step explanation:

For this, we can simply use the pi times r squared because we have the radius.

simplify pi to 3.14, so we can do 3.14 times 3 squared.

we get 9x 3.14, which is 28.26.

In the U.S thirteen of twenty cans are recycled. What % of cans are recycled?
madam [21]

A percent is how many out of 100.

13/20 is how many out of 100?

You multiply the top and bottom by 5, as 5x20 is 100

13x5 is 65

Therefore, 65 out of every hundred cans, or 65%, are recycled

VikaD [51]

Answer:

Answer is 1/13

Step-by-step explanation:

Here we are not intimated about the first (01) twelve (12) cards that are shown, the probability that the thirteenth (13) card dealt is a King, if this is the same as the probability that the (01) first card shown, or in fact any particular card dealt is a King, then it equals:

=4/52

=1/13 ANS
