Answer:
Diameter is the second option
Radius is the first option
Circumference is the third option
Area is the sixth option.
Step-by-step explanation:
Diameter is the distance between two circles from one end to another.
Radius is from the center to any part of the circle
To find cirumfrnce it’s diameter*π
To find area is πr^2 or in this case π*radius*radius
The perimeter of a square garden is (20k+36) feet. Write an expression
Answer:

The value of y can be calculated by using properties of parallelogram and which is 7, So option C is correct
What are the properties of parallelogram ?Opposite sides are parallel: The pairs of opposite sides of a parallelogram are always parallel to each other.
Opposite sides are equal in length: The pairs of opposite sides of a parallelogram are equal in length.
Consecutive angles are supplementary: The consecutive angles of a parallelogram are always supplementary, meaning that they add up to 180 degrees.
Diagonals bisect each other: The diagonals of a parallelogram bisect each other, meaning that they intersect at the midpoint of each other.
The sum of the interior angles is 360 degrees: The sum of the interior angles of a parallelogram is 360 degrees.
Given that,
A parallelogram JKLM,
And in that,
MT = 8y+18
KT = 12y - 10
So, according to properties of parallelogram
the intersection point divides diagonals into two equal parts
So, it can be written as,
8y+18 = 12y - 10
18 + 10 = 12y - 8y
28 = 4y
y = 7
Hence, the value is 7

if y varies inversely as x, and y =35 when x =14, find x when y =15.
Answer:
[tex]x = 32 \frac{2}{3} [/tex]
Step-by-step explanation:
[tex]y = \frac{k}{x} ,where \: k \: is \: a \: constant.[/tex]
Let's find the value of k first.
When y= 35, x= 14,
[tex]35 = \frac{k}{14} [/tex]
k= 14(35)
k= 490
Substitute the value of k into the equation:
[tex]y = \frac{490}{x} [/tex]
When y= 15,
[tex]15 = \frac{490}{x} [/tex]
15x= 490
x= 490 ÷15
[tex]x = 32 \frac{2}{3} [/tex]

Resuelve usando el método de sustitución o el de eliminación. Para un juego de baloncesto se vendieron 1,850 boletos. Se recaudo un total de $ 8,800. Si los boletos de niños cuestan $ 4 y los de adultos cuestan $ 6. ¿Cuántos boletos de cada clase se vendieron?
Answer:
Se vendieron 700 boletos para adultos y 1,150 boletos para niños.
Step-by-step explanation:
Primero tenemos que definir dos variables:
x = número de boletos de niños vendidos
y = número de boletos de adultos vendidos.
Entonces podemos escribir la recaudación total como:
x*$4 + y*$6
Y sabemos que la recaudación total fue $8,800, entonces:
x*$4 + y*$6 = $8,800
También sabemos que se vendieron 1,850 boletos, entonces:
x + y = 1,850
Entonces tenemos el sistema de ecuaciones:
x*$4 + y*$6 = $8,800
x + y = 1,850
En este caso podemos utilizar el método de sustitución, para ello primero debemos aislar una de las variables en una de las ecuaciones.
Si aislamos x en la segunda ecuación tenemos:
x = 1,850 - y
Ahora podemos sustituir esto en la otra ecuación para obtener:
(1,850 - y)*$4 + y*$6 = $8,800
Ahora podemos resolver esto para y.
$7,400 - y*$4 + y*$6 = $8,800
y*$2 = $8,800 - $7,400 = $1,400
y = $1,400/$2 = 700
Entonces se vendieron 700 boletos para adultos.
Ahora podemos usar la ecuación x = 1,850 - y para obtener el valor de x.
x = 1,850 - y
x = 1,850 - 700 = 1,150
Se vendieron 1,150 boletos para niños.

Answer:
30cm
Step-by-step explanation:
The perimeter of the triangle is the sum of all of its sides
Since the triangle is an isosceles triangle, then AC = BC
Since AC = 3cm + 9cm = 12cm, then;
AC = BC = 12cm
For AB;
AB = 3cm + 3cm
AB = 6cm
Perimeter of the polygon = AC+BC + AB
Perimeter of the polygon = 12cm + 12cm + 6cm
Perimeter of the polygon =30cm
please solve for M<QTR
Answer:
m∠QTR = 98°
Step-by-step explanation:
From the picture attached,
Radii of the circle are TQ and TR measuring equal lengths.
Therefore, ΔTQR is a isosceles triangle.
Opposite angles of the equal sides will be equal in measure.
m∠RQT = m∠TRQ = 41°
By angle sum theorem,
m∠RQT + m∠TRQ + m∠QTR = 180°
41° + 41° + m∠QTR = 180°
m∠QTR = 180° - 82°
= 98°
Therefore, m∠QTR = 98°
Sphere A has radius 6 inches and sphere B has diameter 14 inches. Find the ratio of the surface area of A to the surface area of B.
Answer:
the ratio of the surface area of A to the surface area of B is 36 ÷ 49
Step-by-step explanation:
The computation of the ratio of the surface area of A to the surface area of B is shown below;
= Surface area of the sphere a ÷ surface area of the sphere b
= 4πr^2 ÷ 4πr^2
= 6^2 ÷ 14 ÷ 2^2
= 36 ÷ 49
hence, the ratio of the surface area of A to the surface area of B is 36 ÷ 49

How does 5x + 15 = 45
HELP PLZ
Answer:
When finding these problems we always have to do the opposite of the operation shown.
In this case its:
5x + 15 = 45
Subtract 15 from both sides (we start off with constants and numbers that are being shown) The reason why its subtraction is because since your adding 15 to 5x the opposite of that is subtraction so use the number shown by itself and subtract it from both sides.
5x = 30
Divide by 5 on both sides since the opposite of 5x is division (only use the number that is shown) We have to get rid of all the numbers on the left.
therefore you'll be left with:
X = 6
Answer:
X=6
Step-by-step explanation:
5x+15=45
5x=45-15
5x=30,divide both sides by 5 to get x
x=6
