Luke has a cylinder with a radius of 5 inches and a height of 6 inches. What is the volume of his cylinder in cubic inches?
Answer:
471.24 cubic inches
Step-by-step explanation:
The formula for the volume of a cylinder =
πr²h
r = Radius = 5 in
h = Height = 6 in
Hence,
Volume = π × (5 in)² × 6 in
= 471.24 cubic inches
Therefore, the volume of his cylinder in cubic inches = 471.24 cubic inches

Find the measure of CGD.
Answer:
23°
Step-by-step explanation:
For this scenario say point G is the center point,
If we look to the left, we see angle FGE has a value of 23
and in this case angle CGD is a congruent angle to FGE therefore the two angles must be the same
so therefore angle CGD should be 23 degrees
Sarah was thinking of a number. Sarah divides by 7, then adds 9 to get an answer of 3. What was the original number?
Answer:
-42
Step-by-step explanation:
x/7 = y
y + 9 = 3
3 - 9 = y
y = -6
-6 * 7 = x
x = -42
Answer:
-42
Step-by-step explanation:
Do it backwards
Start with 3
SUBTRACT 9 to get -6
MULTIPLY by 7 to get -42.
Check:
Start: -42
Divide by 7: -6
Add 9: 3

Find the surface area of the triangular prism. The base of the prism is an isosceles triangle.
Answer:
Surface area = 505cm²
Step-by-step explanation:
Surface area of the triangular prism. = 2B + ph
B is the base area
p is the perimeter of the triangle
h is the height of the triangle
Base area = 1/2 * base * height
Base area = 1/2 * 18 * 40
Base area = 9 * 40
Base area = 360cm²
Perimeter of the triangle = 41 + 41 + 18
Perimeter of the triangle = 100cm
height of the prism = 45cm
Surface area = 360 + 100 + 45
Surface area = 505cm²

Answer:
A quadrilateral has a parallelogram if one pair of opposite sides is congruent and parallel. Parallelograms are designed to have diagonals that bisect one another. When ABCD is bisected by — BD and —AC, then ABCD is a parallelogram.
Step-by-step explanation:
Answer:
A quadrilateral has a parallelogram if one pair of opposite sides is coinciding exactly when superimposed and parallel. Parallelograms are designed to have diagonals that bisect one another. When abcd is bisected by bd and ac, then abcd is a parallelogram.

The relationship is linear, but it takes some doing.
Step-by-step explanation:
Remark
This is a very interesting problem. I've never seen one quite like it. There is probably a much better way of solving it, but I did not discover it.
You have to introduce another variable which I labeled as z.
Let time = x
Let distance = y
Let the step away from the starting point = z which will be the same for x and y. So 18 and 16 the step away from the start is 3.
So as the time increases, the distance decreases. What we are going to do sort of resembles a parametric relationship.
t starts with 10
x = 10 + 4*(z - 1) and increases by 4 with each step
d starts with 20 and decreases by 2 with each step
y = 20 - (z - 1)*2
Now solve for z in each of the forgoing equations.
x = 10 + 4z - 4
x = 6 + 4z
x - 6 = 4z
(x - 6)/4 = z
y = 20 - 2z + 2
y = 22 - 2z
y - 22 = - 2z
(y - 22)/-2 = z
Since the zs must be kept the same, the left sides are equated
(x - 6)/4 = (y - 22)/-2 Cross multiply
-2(x - 6) = 4(y - 22) Remove the brackets.
-2x + 12 = 4y - 88 add 88 to both sides.
-2x + 100 = 4y Switch the sides
4y = - 2x + 100 Divide by 4
y = -1/2 x + 25
Now for sure you have to try this.
Let x = 14
y = -1/2 * 14 + 25
y = -7 + 25
y = 18
Try another one
Let x = 22
y = -1/2 * 22 + 25
y = - 11 + 25
y = 14
Those two at least check.
If z=2
3 (x-12) and x=39, then what is z?

Answer:
The area of the polygon is 624.5 square feet.
Step-by-step explanation:
The total area of the figure ([tex]A[/tex]), in square feet, is the sum of the areas of two triangles and a rectangle, that is:
[tex]A = A_{I}+A_{II}+A_{III}[/tex] (1)
Where:
[tex]A_{I}[/tex] - Area of the big triangle, in square feet.
[tex]A_{II}[/tex] - Area of the small triangle, in square feet.
[tex]A_{III}[/tex] - Area of the rectangle, in square feet.
Then, we expand the formula by using all dimensions presented in the image attached:
[tex]A = \frac{1}{2}\cdot (25\,ft)\cdot (33\,ft-8\,ft) + \frac{1}{2}\cdot (8\,ft)\cdot (43\,ft-35\,ft) + (35\,ft)\cdot (8\,ft)[/tex]
[tex]A = 624.5\,ft^{2}[/tex]

If 27 ×32 = 3x×2y;find the values of x and y
Answer:
Step-by-step explanation:
hello :
27 ×32 = 3x×2y
means : 27 ×32 = 6xy
xy= (27 ×32)/6
xy = 144
but : 144 =12² = (4×3)²=(2²×3)²
144=2^4 ×3²
so : xy = 2^4 ×3²
if x and y the integere numbers so x and y are the divisors of 144

Expresa en forma algebraica. ⦁ El cuadrado de un número aumentado en 1. ⦁ Cinco veces un número menos 8. ⦁ El número siguiente a un múltiplo de 5. ⦁ Un número impar.
Answer:
1) N^2 + 1
2) 5*N - 9
3) n*5 + 1 (con n entero)
4) n*2 + 1 (con n entero)
Step-by-step explanation:
1) El cuadrado de un número aumentado en 1.
Podemos definir a N como el número.
El cuadrado de N es:
N^2
Y a esto lo tenemos que aumentar en 1, entonces tenemos:
N^2 + 1
Esto es el cuadrado de un número aumentado en 1.
2) Cinco veces un número menos 8.
Esto es:
5*N (5 veces un número)
Y a esto le restamos 8, para obtener:
5*N - 8
3) El número siguiente a un múltiplo de 5
Un multiplo de 5 se escribe como:
n*5
Donde n es un número entero.
El numero siguiente es:
n*5 + 1
4) Un número impar.
Bien, sabemos que un número par es un multiplo de 2.
Entonces:
n*2 es un número par.
Entonces, n*2 + 1 tiene que ser un numero impar.
En este caso la expresión algebraica es:
n*2 + 1

Prove: The diagonals of a square are perpendicular.
Answer:
Step-by-step explanation:
Slope of AC= (a-0)/(a-0) = 1
Slope of BD = (0-a)/(a-0) = (-a)/a =-1
Slope of AC x Slope of BD =1 x -1 = -1
Therefore AC perpendicular to BD

Answer:
-Entire triangle region : 120 sq.cm
-Area of semi circle : 100.53 sq.cm
-Entire composite figure : 220.53 sq.cm
Step-by-step explanation:
Area of triangle = ½ × base × height
= ½ × (8+8) × 15
=½ × 16 × 15
= 120 sq.cm
[tex]area \: of \: semi \: circle = \frac{1}{2} \pi {r}^{2} \\ = \frac{1}{2} \times \pi \times {8}^{2} \\ = \frac{1}{2} \times \pi \times 64 \\ = 32\pi[/tex]
=100.530.......
=100.53 sq.cm (rounded to 2 decimal place)
Area of entire figure = 120 + 100.5353
= 220.53 sq.cm
