Question 2-4 Please

Answers

Answer 1

Answer:

Step-by-step explanation:

2) a) You have to find the area of semicircle.

r = d/2 = 12/2 = 6 mm

Area of semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]

                              [tex]= \frac{1}{2}*3.14*6*6\\\\= 3.14*3*6\\\\= 56.52 mm^{2}[/tex]

b) r = 10 cm

Area of quadrant = [tex]\frac{1}{4}\pi r^{2}[/tex]

                             [tex]= \frac{1}{4}*3.14*10*10\\\\=3.14*5*5\\\\= 78.5 cm^{2}[/tex]

3) d = 10 m

r = d/2 = 10/2 = 5 m

Area of circular garden = πr²

                                       = 3.14 * 5 * 5

                                       = 78.5 m²

Area of rectangular pool = 8 * 6 = 48 m²

Area of the garden covered in grass = area of the circular garden - area of pool

   = 78.5 - 48

   = 30.5 m²

4) a) r = 60 cm

Area of the top of the circular table = πr²

             = 3.14 * 60 *  60

            = 11304 cm²

diameter of base = 30 cm

r = 30/2 = 15 cm

Area of circular base = 3.14 * 15 * 15

                                   = 706.5 cm²

Three neighbors plan to complete fencing projects this spring. As shown in the diagrams below, Neighbor A plans to fence in his rectangular backyard with a 6-foot tall wooden privacy fence. Neighbor B plans to construct a circular chain link fence around his pool. And, Neighbor C is putting a vinyl fence around three side of his front yard. Note: Diagrams are not drawn to scale. Intended fences are marked with a dashed line.

Answers

Answer:

- The neighbor that has the most amount of fence to put up is: Neighbor A.

- The neighbor that has the least amount of fence to put up is: Neighbor C.

Step-by-step explanation:

To calculate the amount of fence that Neighbor A has to put up, you need to add the following distances:

Convert yards to feet (Remember that :

To calculate the amount of fence that Neighbor B has to put up, you need to use the formula for calculate the circumference of a circle:

Where r is the radius.

In this case, the radius is:

Substituting, you get:

To calculate the amount of fence that Neighbor C has to put up, you need to add the following distances:

Therefore, the neighbor that has the most amount of fence to put up is: Neighbor A.

The neighbor that has the least amount of fence to put up is: Neighbor C.

Solve using the quadratic formula 1

Answers

Answer:

Step-by-step explanation:

Unless we set x^2 + 8x + 15 equal to zero, we don't have an equation to be solved.  I will assume that the problem is actually x^2 + 8x + 15 = 0.

The coefficients of this quadratic are {1, 8, 15}, and so the "discriminant" b^2 - 4ac is (8)^2 - 4(1)(15), or 4.  Because the discriminant is positive, we know that there are two real, unequal roots.

Continuing with the quadratic formula and knowing that the discriminant is 4, we get:

      -8 ± √4           -8 ± 2

x = ---------------- = --------------- , or x = -2 ± 1:  x = -3 and x = -5

Step-by-step explanation:

The volume of the square pyramid is 96 cm³.

How to find the volume of a square pyramid?

You can locate the extent of a normal square pyramid with the use of the volume formula= base location² × height / 3. Take be aware that the bottom vicinity equals the square of the pyramid's base side period. However, the peak is the perpendicular distance between the pyramid's base and the pyramid's vertex.

By using the given formula, we get

V= a² h/3

=6² * 8 / 3 = 96

The answer is 96 cm³.

The volume of a pyramid is found using the formula V = (1/3) B*h, where 'B' is the base area and 'h' is the height of the pyramid.

Step 1: Our output value is 700.

Step 2: We represent the unknown value with $x$x​.

Step 3: From step 1 above,$700=100\%$700=100%​.

Step 4: Similarly, $x=42\%$x=42%​.

Step 5: This results in a pair of simple equations:

$700=100\%(1)$700=100%(1)​.

$x=42\%(2)$x=42%(2)​.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{700}{x}=\frac{100\%}{42\%}$

700

x​=

100%

42%​​

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{700}=\frac{42}{100}$

x

700​=

42

100​​

Therefore, 42% of 700 is 294.

What is function Rule?

A function rule is the relationship between the dependent and independent variables in the form of an equation.

As per the given data if we follow the pattern we get a relation between Output and Input as:

Output= Input-12

or, input= Output + 12

So, we have to find the input when output= -6

Input = -6+12

         =+6

Now, to find the output when input is -10

output= -10-12
