Diego says a quadrilateral with 4 congruent sides is always a regular polygon. Mai says it never is one.
Do you agree with either of them?
Answer:
A regular polygon all the angles, as well as all the sides, are equal.
Diego's claim is the quadrilateral with four congruent sides is always a regular polygon. He is only mentioning that the sides are equals.
He has not mentioned anything about the angles, the angles may or may not be equals.
In the case, if all the angles are equal too, then the claimed quadrilateral will be a regular polygon as shown in figure(a).
So, for this case, Diego's claim is correct while Mai's claim is also wrong.
While if all the angles are not equal, then the claimed quadrilateral will not be a regular polygon as shown in figure(b).
In this case, Diego's claim is wrong while Mai's claim is correct.
So, overall, considering both the case together, none of them have the correct claim.
So, both are wrong.

Find the length of the third side. If necessary, write it in simplest radical form.
Answer:
a = sqrt(7)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
where a and b are the legs and c is the hypotenuse
a^2 +3^2 = 4^2
a^2 +9 = 16
a^2 = 16-9
a^2 = 7
Taking the square root
a = sqrt(7)

The perimeter of a rectangle is 40 inches. If the width is 9 inches, what is the area of the rectangle?
Answer:
99 in²
Step-by-step explanation:
Perimeter = 2(length) + 2(width)
40 = 2(length) + 2(9)
40 = 2L + 18
40 - 18 = 2l
22 = 2l
L = 11
Area = length x width
Area = 9 x 11 = 99
99 square inches

Answer:
quiz score if no homework is done
Step-by-step explanation:
The y-intercept is the point where the horizontal coordinate is zero. That axis is defined as "hours per week spent on homework". So, the y-intercept is the function value when zero hours per week are spent on homework.
The function value is defined as "expected quiz score".
Then the y-intercept is ...

Answer:
115 in.^2
Step-by-step explanation:
The total surface area is the sum of the areas of the square base and the 4 congruent triangular faces.
SA = b^2 + 4 * bh/2
SA = (5 in.)^2 + 4 * (5 in.)(9 in.)/2
SA = 25 in.^2 + 2 * 45 in.^2
SA = 115 in.^2

1) Move the decimal point 2 times to left in the number so that number, 940 so it's between 1-10: 9.4 or 9.40
2) After we moved our decimal point to the left, the decimal count would be 12 and that we moved 2 places to the left
3) We know that the notation is a x [tex]10^{b}[/tex]
a=9.4 and 6=2

If the ratio of x+y to x-y is 2/5, what's the ratio of y to x ?
9514 1404 393
Answer:
y/x = -3/7
Step-by-step explanation:
Write the given relationship and solve for y/x.
(x +y)/(x -y) = 2/5
5(x +y) = 2(x -y) . . . . . multiply by 5(x-y)
5x +5y = 2x -2y . . . . . eliminate parentheses
7y = -3x . . . . . . . . . . . add 2y-5x
y/x = -3/7 . . . . . . . . divide by 7x
Solve the equation for all values of x.
(x2 – 16)(x2 + 49) = 0
Answer:
-4, 4, 7i, -7i
Step-by-step explanation:
Basically any or each bracket must be equal to 0. If x^2+16 = 0, then x can be 4 and -4, and if x^2+49 is 0, then x =7i or -7i

Answer:
x = 91° , y = 52°
Step-by-step explanation:
Opposite angles add up to 180°.
Therefore :
1. x° + 89° = 180°
x° = 180° - 89°
x° = 91° #
2. 76° + 2y° = 180°
2y° = 180° - 76°
2y° = 104°
y° = 104° / 2
y° = 52°#

The outer radius of a cylindrical metal tube is R and t is the thickness of the metal. a Show that the volume, V. of metal in a length.7 units, of the tube is given by V. = m(2R - 0). b Hence calculate V when R = 7.5.1 = 1 and l= 20
Complete question is;
The outer radius of a cylindrical metal tube is R and t is the thickness of the metal.
A) Show that the volume, V, of metal in a length, l units, of the tube is given by V = πlt(2R - t)
B) Hence calculate V when R = 7.5. t = 1 and L = 20
Answer:
A)V = πlt(2R - t)
B)V = 879.65
Step-by-step explanation:
A) Formula for volume of a hollow cylinder is; V = π(R² - r²)h
Where;
R is outer radius
r is inner radius
h is height/length of tube
Now, we are told thickness is t.
Thus; R - r = t
Also, h = l
Thus;
V = π(R² - r²)h
Let's factorize this to get;
V = π((R + r)(R - r))l
V = π((R + r))lt
Since R - r = t
Then, r = R - t
Thus;
V = π(R + R - t)lt
V = πlt(2R - t)
B) when R = 7.5, t = 1 and l= 20;
V = πlt(2R - t)
V = π × 20 × 1(2(7.5) - 1)
V = 879.65

The area of an isosceles triangle is 52 square inches. The height is 8 in. What is the length of the base?
Answer:
base = 13 in
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here A = 52 and h = 8 , then
[tex]\frac{1}{2}[/tex] b × 8 = 52
4b = 52 ( divide both sides by 4 )
b = 13
An angle measures 89.8° more than the measure of its complementary angle. What is the measure of each angle?
Complementary angles always are 90 degrees when added to each other, so:
x = angle 1
x + 89.8 = angle 2
x + x + 89.8 = 90
2x = 90 - 89.8
2x = 0.2
x = 0.1
angle 1 = 0.1 degrees
angle 2 = 0.1 + 89.8 = 89.9 degrees
if you want to check, just sum one to the other and see if they equal 90, like this: 89.9 + 0.1 = 90
