The swimming pool shown is a right prism with concave hexagonal bases.... pls help

Answer:

b = 30 + c ÷ 2

Step-by-step explanation:

b = brownies

c = cake

Answer:

A)The angles in the smaller prism measure 90 degrees.

B)The perimeter of the rectangular bases changes by a factor of 2.  

E)The area of the rectangular bases changes by a factor of 4.

Step-by-step explanation:

The right rectangular prisms are similar.

Which statements are correct? Check all that apply.

A)The angles in the smaller prism measure 90 degrees.

B)The perimeter of the rectangular bases changes by a factor of 2.

C)The surface area changes by a factor of 8.

D)The larger prism has twice the volume of the smaller prism.

E)The area of the rectangular bases changes by a factor of 4.

Solution:

Two polygons are said to be similar if they have the same shape, the ratio of their sides are in the same proportion and they have the same size of angles.

A) Since the bigger prism has angles with measure of 90°, hence the angles in the smaller prism will also measure 90.

Option A is correct.

B) Perimeter of bigger prism base = 2(2.2 + 0.8) = 6

Perimeter of smaller prism base = 2(1.1 + 0.4) = 3

The perimeter of the rectangular bases changes by a factor of 2 (6 / 3).

Option B is correct.

C) Surface area of bigger prism = 2(3.2*0.8 + 2.2*0.8 + 3.2*2.2) = 22.72

Surface area of smaller prism = 2(1.6*0.4 + 1.1*0.4 + 1.6*1.1) = 5.68

The surface area does not change by a factor of 8 (22.72 / 5.68 ≠ 8)

Option C is wrong

D) Volume of bigger prism = 2.2 * 3.2 * 0.8 = 5.632

Volume of smaller prism = 1.1 * 1.6 * 0.4 = 0.704

The larger prism volume is not twice of the smaller prism

Option D is wrong

E) Area of bigger prism base = 2.2*0.8 = 1.76

Area of smaller prism base = 2.2*0.8 = 0.44

The area of the rectangular bases changes by a  factor of 4 (1.76 / 0.44 = 4)

Answer: [tex]x+3[/tex]

Step-by-step explanation:

Given

[tex](x+5)[/tex] is a factor of [tex]x^2+8x+15[/tex] , that is

If [tex]x^2+8x+15[/tex] is divided by [tex](x+5)[/tex], it yields 0 remainder

Solve the quadratic equation

[tex]\Rightarrow x^2+8x+15=0\\\Rightarrow x^2+3x+5x+15=0\\\Rightarrow (x+3)(x+5)=0\\\Rightarrow x=-3,-5[/tex]

Therefore, [tex]x+3[/tex] is another factor of the quadratic equation.

The measure of the unknown angle is 70 degrees

In circle geometry, there is a theorem that states that the angle at the centre of a circle is twice the angle at the circumference

Given the following parameters;

Angle at the circumference = x

Angle at the centre = 140 degrees

Using the given theorem;

140 = 2x

Swap

2x = 140

x = 140/2

x = 70

Hence the measure of the unknown angle is 70 degrees
