what was the original weight of the ball ?
Answer:
16.5

A is the correct answer
Step-by-step explanation:
If you plug y=x+10 in for the Y variable you just have to solve by multiplying.
1.) It should look like this:
2x + 3(x +10) = 40
2.) You will distribute the three which will make the equation look like this:
2x + 3x + 30 = 40
3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.
but 16.5 is the answer

Step 1: Find out how many pens he bought
12 pens per pack
Charles bought 60 packs
60 packs x 12 pens = 720 pens
Step 2: Find out how much Charles spent
2.80 per pack
Charles bought 60 packs
60 x 2.80 = 168 pounds
Step 3: Find out how many pens Charles sold
Charles sold 2/3 of his pens
2/3 x 720 = 480
Step 4: Find out how manypens he sold
Charles sold the pens for 40p
40p x 480 = 19200p
Step 5: Convert pences to pounds
19200p = 192 pounds
Step 6: Find the profit
192 - 168 = 24 pounds
Step 7: Therefore statement
Therefore he mad 24 pounds of profit

128) Los vertices de esta figura son:
(-2,1) (4,1) (4,-2) (0,-3)
129) Siempre se busca primero la coordenada horizontal! esa es la coordenada en "x" . Despues es la coordenada vertical , que es la coordenada en "y" .
Por lo tanto , para el punto de arriba , la coordenada horizontal es 1 y la vertical es 3, por lo tanto la coordenada del punto es (1,3) .
Las coordenadas de los puntos son entonces.
[tex](1,3)\\(3,0)\\(2-2)\\(-1,-2)\\(-2,1)[/tex]
130) Las coordenadas del vertice faltante son (1,-2)
131) Tenemos que representar un hexágono concavo en el plano cartesiano.
Un hexágono concavo es un poligono de 6 lados y 6 ângulos, siendo uno de estos últimos mayor a 180 grados.
Podemos dibujar de la siguiente manera: elegir 5 vertices como si fuera un hexágono irregular cualquiera alrededor del origen de coordenadas, y luego elegir a (0,0) como el ultimo vertice. Esta es una de las varias maneras de resolverlo, no la unica .
Como ejemplo, puede ser el siguiente hexágono:
132) Si tenemos los vertices K y L, una forma de completar un triangulo isosceles con un tercer vertice es colocar este vertice en algun punto de la linea perpendicular a KL y que pasa por su punto medio.
Las coordenadas de M, el punto medio de KL se puede calcular como el promedio de las coordenadas de los extremos K y L:
[tex]Xm=\frac{xK+xL}{2} =\frac{-1+(-1)}{2} =-\frac{2}{2} =-1\\Ym=\frac{Yk+yL}{2} =\frac{2+(-4)}{2} =\frac{-2}{2} =-1[/tex]
Como la linea definida por KL es una linea vertical, sus lineas perpendiculares seran lineas horizontales. Entonces ,la recta y=-1 es perpendicular a KL y passa por el punto medio de KL.
Cualquier vertice con coordenadas (x,-1), excepto (-1,-1) , formaran un triangulo isosceles.
Como ejemplo , seleccionemos un vertice en (5,-1):
Como tenemos un eje de simetria en y=-1 , el triangulo KLM es isosceles.
132) Si tomaremos el ejemplo anterior y nos corrieramos del eje de simetria obterndriamos un triangulo escaleno, es decir, con 3 lados con distintas longitudes.
NOTA: Tener cuidado que por casualidad no coincidan KM o LM con KL (longitud 6).
Por ejemplo, si corremos M hasta (5,0) obtendremos un triangulo isosceles, dado que el segmento KM tendria longitud 6, al igual que KL.
Para asegurarnos que los tres lados tengan longitudes diferentes, formamos un triangulo rectangulo con dos catetos con diferentes longitud. Un cateto es KL, de longitud 6, y el otro cateto sera KM , de longitud 3 si colocamos a M en (2,2):

Suppose A is (-3,6) when it starts out.
When A is reflected across the y axis, it takes on the opposite sign.-3 becomes + 3Nothing happens to the y value of the point from this transformationThe new point is X(3,6)Now we take the reflected point and move it three units. up
Up means increase the y value of the new point (X)The y value = 6Increase the y value by 3This makes 6 + 3 = 9So after all that X becomes (3,9)Answer:

Answer:
a = 84°
b = 36°
c = 24°
d = 84°
e = 132°
Step-by-step explanation:
The parameters of the workers in the office are;
The number of staffs in the office = 60 staffs
The take-aways are pizza, curry, fish & chips, kebab and other
The frequency for the above take-aways = 14, 6, 4, 14, and 22 respectively
The variables for the angles representing the above take-aways on the pie chart = 'a', 'b', 'c', 'd', and 'e'; respectively
In order to find the size of the angles that represent each group of workers in the pie chart, we find the ratio of the group size to the total number of workers and we multiply the result by 360° as follows;
∠a = 360° × 14/60 = 84°
∠b = 360° × 6/60 = 36°
∠c = 360° × 4/60 = 24°
∠d = 360° × 14/60 = 84°
∠e = 360° × 22/60 = 132°

Jonathan is putting a border around a right triangle and needs to figure out the triangle's height. If the triangle has a base length of 4 cm and a total area of 24 cm², what is the height?
Step-by-step explanation:
formula to find area of a triangle:
A=1/2 × base × height(h)
insert the values into the formula:
24=1/2 × 4 × h
solve for h :
24=2h
24/2=h
h = 12 cm ( Ans )
The height of triangle will be 12 cm.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The triangle has a base length of 4 cm.
And, A total area of 24 cm².
Now,
We know that;
Area of right triangle = 1/2 × Base × Height
⇒ 24 = 1/2 × 4 × h
⇒ 24 = 2 × h
⇒ h = 24 / 2
⇒ h = 12 cm
Thus, The height of triangle = 12 cm.

what is the value of x in the figure please help I’ll give you brainliest :)
Answer:
37°
Step-by-step explanation:
(4x + 2)° = 150° [Vertically Opposite Angles]
=> 4x = 150 - 2
=> 4x = 148
[tex] = > x = \frac{148}{4} [/tex]
=> x = 37° (Ans)
Angle (4x+2)° and angle 150° are vertically opposite angles so, their measures will be equal.
Which means :
[tex] =\tt 4x + 2 = 150[/tex]
[tex] =\tt 4x = 150 - 2[/tex]
[tex] = \tt4x = 148[/tex]
[tex] =\tt x = \frac{148}{4} [/tex]
[tex]\hookrightarrow \: \color{plum}x = 37[/tex]
Let us check whether or not we have found out the correct measure of x by placing 37 in the place of x:
[tex] =\tt 4 \times 37 + 2 = 150[/tex]
[tex] = \tt148 + 2 = 150[/tex]
[tex] =\tt 150 = 150[/tex]
Since the measures of both the angles are equal we can conclude that we have found out the correct value of x.
Thus, the value of x in this figure = 37
Therefore, the correct option is (A) 37.

What is (2+2) +4 equal to best answer gets brainly
Answer:
8
Step-by-step explanation:
A swimming pool had 30 gallons of water in it. Then water was added to the pool at a rate of 5 gallons per second. The function y= 5t + 30 describes the relationship between the number of gallons, y, and the number of seconds water was added, t. Select all of the ordered pairs that correspond to input-output pairs for the function.
A. (45,3)
B. (3,45)
C. (0,30)
D. (30,0)
The (45,3) and (30,0) are the correct-ordered pairs that correspond to input-output pairs for the function.
What is function?Each element of X receives exactly one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and co-domain, respectively.
Given the function:
y = 5t +30,
Here y is the no of gallons and t is the time.
Take the values of option A and substitute in the function,
45 = 5 × 3 +30
45 = 45
Hence, it is the correct-ordered pair,
Similarly, take option b
3 = 45 × 5 +30
3 ≠ 255
Now take option c,
0 = 30 × 5 +30
0 ≠ 180
Take the last option,
30 = 0 × 5 +30
30 = 30
Hence, it is also the ordered pair.
Therefore, the (45,3) and (30,0) are the correct-ordered pairs that correspond to input-output pairs for the function.

Answer:
a = 32
Step-by-step explanation:
Step 1: Understand the question
The 2 angles inside are supplamentary angles which means they add up to 180
Step 2: Set up the equation
If the 2 angles added up equal to 180 you can create an equation that states
[tex](2a+7)+109=180[/tex]
Step 3: Solve for the variable
[tex](2a+7)+109=180\\2a+7+109\\2a+116=180\\2a=64\\\frac{2a}{2}=\frac{64}{2}\\a=32[/tex]
