GEOMETRY For what values of r will the area of the shaded region be greater than or equal to 12 square units? Write your answer as an
inequality
Answers
Answer:
Step-by-step explanation:
Find the area of the shaded region in terms of r.
1. The area of the circle with radius r is
2. The area of the square with diagonal 2r is
3. The area of the shaded region is the difference
Since the area of the shaded region must be greater or equal to then
This inequality is solved only in positive numbers, because r cannot be negative.

Let c = hypotenuse
a = one of the legs of the triangle
b = the other leg of the triangle
Use the Pythagorean Theorem to solve for the measure of the hypotenuse:
c^ 2 = a^2 + b^2
c^ 2 = (4)^2 + (4)^2
c^ 2 = 16 + 16
c^2 = 32
Next, take the square root of each side of the equation to solve for c:
√(c^2) = √(32)
c = 4√(2)
Therefore, the correct answer is Option 3) 4√(2).

The perimeter of a rectangle is 78 units. The length is 5 units more than the width. Find the length.
Answers
Answer:
W = 8.5 units; L = 30.5 units
Step-by-step explanation:
The formula for the perimeter of a rectangle is P = 2L and 2W, where L and W represent the length and the width respectively. Here, L = 3W + 5. Adapting the formula P = 2L and 2W, we get: 78 = 2L + 2W = 2(3W + 5) + 2W, or 6W + 10 + 2W = 78, or 8W = 68, or W = 68/8 = 8.5 units If W = 8.5 units, then L = 3(8.5 units) + 5 units = 30.5 units

Find SURFACE AREA
Answers
Answer:
132 cm²
Step-by-step explanation:
The area of the two triangular ends is ...
A = 2(1/2)(bh) = (4 cm)(3 cm) = 12 cm² . . . . . area of both triangles
The area of the three rectangular faces is ...
A = (b1)(h) +(b2)(h) +(b3)(h) = (b1 +b2 +b3)(h)
= (4 cm +3 cm +5 cm)(10 cm) = 120 cm²
Then the total surface area is ...
triangle area + rectangle area = (12 cm²) +(120 cm²) = 132 cm²
A system of equations is shown. x = 10 3x + 5y = 20
Answers
Answer:
(10, - 2 )
Step-by-step explanation:
x = 10 → (1)
3x + 5y = 20 → (2)
Substitute x = 10 into (2)
3(10) + 5y = 20
30 + 5y = 20 ( subtract 30 from both sides )
5y = - 10 ( divide both sides by 5 )
y = - 2
solution is (10, - 2 )

what pattern do you noticed for each column
Answers
Answer:
If you look at the "Standard Form" column, you can take any number from an upper row and divide it by 4 to get the number in the row below it.
For example: You can take 256 and divide it by 4, and that will give you 64. Like wise, if you take 64 and divide it by 4 you will get 16.
This tells us that every time you add 4 to the equation, your answer will keep increasing 4 times.
