Find the area of the shaded region
kodGreya [7K]

Answer:  21.994 cm²

Step-by-step explanation:

Area of the shaded region = Area of the bigger circle - the areas of the two smaller circles.

Formula for finding area of a circle       =  πr² where π is a constants . It has value of         22/7 or 3.142

Now area of the bigger circle                = 3.142 x 3²

                                                                  = 3.142 x 9

                                                                  = 28.278 cm²                                       Now are of the two smaller triangle        = 3.142 x 1² x 2

                                                                   = 6.284 cm².

Therefore are of the shaded region        = 28.278 - 6.284

                                                                   = 21.994 cm²

D’Andra has a dentist appointment in 5 weeks. There are 7 days in a week. How many days are in 5 weeks?
Lisa [10]

Answer:

A. 35

Step-by-step explanation:

Each week has 7 days, and we have 5 weeks.

Week 1 has 7 days.

Week 2 has 7 days.

Week 3 has 7 days.

Week 4 has 7 days.

Week 5 has 7 days.

We can add all these together to get the total number of days: 7 + 7 + 7 + 7 + 7 = 7 * 5 = 35.

Thus, the answer is A.

Hope this helps!

So yeah if someone can help me with
Law Incorporation [45]

Answer:

y = x - 5

Step-by-step explanation:

The equation of the line parallel to the line $ ax + by + c_1 = 0$ is $ ax + by + c_2 = 0 $.

That is, equations of parallel lines differ only by constant.

The given equation is $ y = x + 4 $

This is written as $ x - y + 4 = 0 $

Therefore, the equation of the line parallel to this line is given by $ x - y + c = 0 $

The value of c is determined using the point given.

Substituting the point (3,-2) we get:

$ 3 + 2 + c = 0$

$ \implies c = -5 $

Therefore, the equation of the line becomes y = x - 5.
