Answer:

5.5 or 5 1/2

Step-by-step explanation:

In order to solve this problem, we first need to set up an equation. Line AB is tangent to circle P. So is line AC. Because these two tangent lines come together at a point, they are congruent, or equal to each other. Now that we know this, we can set up an equation in order to solve for the value of y.

3y + 4 = 11y

Now solve for y.

- 3y - 3y

4 = 8y

÷8 ÷8

y = 0.5 or 1/2

Now that we know what the value of y is, we can plug that number into the AB equation to figure out what the measurement of line AB is.

3(0.5) + 4 =

1.5 + 4 =

5.5 or 5 1/2

We now know the measurement of line AB. I hope this helps and isn't too confusing. Please let me know if you need any more help. Good luck!

Area of shaded region = Area of bigger rectangle - Area of smaller rectangle.

Area (big) :

$\qquad❖ \: \sf \:13 \times 6$

$\qquad❖ \: \sf \:78 \: \:c m {}^{2}$

Area (small) :

$\qquad❖ \: \sf \:11 \times 4$

$\qquad❖ \: \sf \:44 \: \: cm {}^{2}$

Area of shaded region :

$\qquad❖ \: \sf \:78 - 44$

$\qquad❖ \: \sf \:34 \: \: cm {}^{2}$

$\qquad \large \sf {Conclusion} :$

Area of shaded region = 34 cm²

Answer:

583

Step-by-step explanation:

The mean of a data set is the average of the data set. It can be found by adding up all of the values and then dividing by the total number of values added. In this case, one is given the mean, and one needs to find a missing value. Since there is a missing element, add one to the total number of values in the data set. The missing element is represented by the parameter (x). Set up an equation and solve:

$\frac{(236)+(342)+(328)+(352)+(352)+(306)+(317)+(x)}{8}=325\\$
