Answer:
£290.70
Step-by-step explanation:
50x5=250
20x2=40
10x7=70
5x3=15
total = 375
375/1.29=290.697
= £290.70
Step-by-step explanation:
$50-5= 50×5
= 250
$20-2=20×2
= 40
$10-7= 10×7
= 70
$5-3= 5×3
15
then,
we add
250 + 40 + 70 + 15 = 379
£1= $1.29
$ = 1/1.29
= 379/1.29
3 expresiones de funcion lineal con valor m mayor que 0
Answer:
Una función lineal es aquella cuya expresión algebraica es del tipo y = mx,siendo m un número cualquiera distinto de 0.
Su gráfica es una línea recta que pasa por el origen, (0,0).
El número m se llama pendiente.
La función es creciente si m > 0 y decreciente si m < 0.
Ejemplo: Vamos a representar gráficamente la función lineal y = 2x.
Para ello, vamos a construir su tabla de valores, pero no debemos olvidar que su gráfica es una recta que pasa por el origen, por lo que bastará dar un valor a x y obtener su correspondiente de y. Después uniremos ese punto obtenido con el origen de coordenadas mediante una línea recta.
Tabla de valores
x

y
2
Así, la representación gráfica de la función en cuestión será la que se muestra a continuación:
Esta unidad interactiva requiere la máquina virtual de Java J2RE.
Ejercicio: Representa en tu cuaderno las siguientes funciones lineales:
a) y = 0,5x b) y = 4x c) y = - 0,75x
- Compara tus resultados con los que se obtienen al modificar el valor de m en la gráfica anterior.
- Observa que la recta está más inclinada cuanto mayor es el valor absoluto de la pendiente.
2. Función afín
Una función afín es aquella cuya expresión algebraica es del tipo y = mx + n, siendo m y n números distintos de 0.
Su gráfica es una línea recta.
El número m es la pendiente.
El número n es la ordenada en el origen. La recta corta al eje Y en el punto (0,n).
Ejemplo: Vamos a representar gráficamente la función lineal y = - 2x + 3.
De nuevo vamos a construir su tabla de valores. En este caso hemos de tener en cuenta que la función ya no pasa por el origen de coordenadas, lo hace por (0,3), puesto que n = 3. Teniendo esto en cuenta volveremos a dar un único valor a la varible independiente (x), para el que obtendremos un valor de la variable dependiente (y), posteriormente uniremos el punto obtenido con el (0,3) mediante una linea recta.
Tabla de valores
x

Esta unidad interactiva requiere la máquina virtual de Java J2RE.
Ejercicio: Representa en tu cuaderno las siguientes funciones afines:
a) y = 0,5x + 1 b) y = x + 2 c) y = 0,75x - 1
- Compara tus resultados con los que se obtienen al modificar el valor de m y n en la gráfica anterior.
3. Ecuaciones y gráficas
Cuando la gráfica de una función es una recta:
Si la recta pasa por el origen de coordenadas, es una función lineal, y = mx, y su pendiente, m, es la ordenada de x = 1.
Si no pasa por el origen, es una función afín, y = mx + n, donde n es la ordenada de x = 0 y m es la ordenada de x = 1 menos n.
Ejemplo: Vamos a determinar la expresión algebraica de las siguientes funciones
Esta unidad interactiva requiere la máquina virtual de Java J2RE.
La recta de color rojo pasa por el origen de coordenadas, por tanto su ecuación será del tipo y = mx. Puesto que pasa por el punto (1,-2) su pendiente será m = -2. Por tanto la función es y = -2x.
La recta de color azul no pasa por (0,0), por lo que su ecuación será del tipo y = mx + n.
Pasa por (0,-1), entonces n = -1.
Pasa por (1,2), entonces m = 2 - n = 2 - (-1) = 3.
La función es y = 3x - 1.

Step-by-step explanation:
cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide
Answer:
To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.
Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).
Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).
To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
First, find out how much stickers you can put on the long side:
12/3 = 4
Next, find out how much stickers you can put on the wide side:
8/2 = 4
Lastly, calculate them together:
4x4=16
So the answer is 16.

Answer:
\(\huge\boxed{\sf x =28 \textdegree}\)
Step-by-step explanation:
Given that,
∠IAK = 62°
∠IAK + ∠IAD = 90° (Complementary angles)
62 + ∠IAD = 90°
Subtract 62 to both sides
∠IAD = 90 - 62
∠IAD = 28°∠IAD = ∠ACB (Corresponding angles are equal)
So,
∠ACB = 28°∠ACB = ∠GCJ (Vertically opposite angles are equal)
So,
28° = x°
OR
x° = 28°\(\rule[225]{225}{2}\)
Answer:
28 degrees
Step-by-step explanation:
If two lines cross each other, it makes 4 angles, and 2 angles from opposite sides have the same length. Since line KL and line IJ crossed, angle KAI and angle LAJ will have the same angle.
--> Angle LAJ is 62 degrees
If we look closely, there is a triangle ABC, and since the question said that line KL and line FG is perpendicular, the angle ALG will be 90 degrees.
We know that in a triangle, there are three angles, and the angle measures combined equals 180.
Since we know two angles: 90 and 62, we take them away from 180 to find the last angle BCA.
--> 180 - 90 - 62 = 28
--> Angle BCA = 28 degrees
Like I said at the beginning, if two lines cross each other, opposite angles are the same size. So angle x will also be equal to angle BCA, which is 28 degrees.
Angle x = 28 degrees
A coin is flipped at the start of every game to determine if Team A (heads) or Team B (tails) will get the ball first.
Part A: Find the theoretical probability of a fair coin landing on heads. (2 points)
Part B: Flip a coin 20 times and record the frequency of each outcome. (4 points)
Part C: Determine the experimental probability of landing on heads. (4 points)
Part D: Compare the theoretical and experimental probabilities. Explain your answer. (2 points)
FORGET THIS QUESTION
Answer:
Step-by-step explanation:
Part A: The theoretical probability of a fair coin landing on heads is 0.5 or 50%. This is because there are two possible outcomes for a coin flip: heads or tails, and assuming the coin is fair, each outcome has an equal chance of occurring.
Part B: The frequency of each outcome after flipping a coin 20 times may vary due to chance, but it is expected to be close to the theoretical probability of 0.5 for heads and 0.5 for tails.
Part C: The experimental probability of landing on heads can be calculated by dividing the frequency of landing on heads by the total number of coin flips. In this example, the experimental probability of landing on heads is:
Experimental probability of landing on heads = 11/20 = 0.55 or 55%
Part D: The theoretical probability of landing on heads is 0.5 or 50%, while the experimental probability of landing on heads after flipping a coin 20 times is 0.55 or 55%. This difference between theoretical and experimental probabilities may be due to chance variation, as the experimental probability is based on a finite number of trials. However, with more trials, the experimental probability is expected to converge to the theoretical probability

. A pair of shoes are $98.75,
if the sales tax is 5%.
a. Find the amount of
sales tax
b. Find the total amount
paid
Answer:
a. saletax = 98.75
100
5 = 98.75
100 1
we cross multiple
5(1) = 100(98.75)
5 = 100(98.75)
divide both side by 5
5 = 100(98.75)
5 5
since 100 can divide 5 so we divide them
= 20(98.75)
amount sale tax = 1975
b. 98.75 × 5 =493.75$

What is a fraction?? don’t copy from googl
pls give a good explanation
Answer:A fraction represents a part of a whole
Step-by-step explanation:
eg: 3/5 by 5/5
please view explanation
Calculations ↓The definition of a fraction is a part of a whole .
If a whole is divided into equal parts, these equal parts are called fractions.
Fractions are written like this :
\(\boxed{\\\begin{minipage}{4cm}fractions\\$\displaystyle\frac{x\xrightarrow{numerator}}{y\xrightarrow{denominator}} \\ \end{minipage}}\)
Where
y = the number of total parts
x = the number of parts taken
Now, it doesn't necessarily have to be a pizza or a cake.
Suppose your companion Danette has 32 pencils. Out of them, 8 pencils are red.
What fraction of the pencils is red?
Total number of pencils = 32 (denominator)
Number of red pencils = 8 (numerator)
So the fraction of red pencils is :
\(\boxed{\\\begin{minipage}{4cm}Danette's\:pencils \\ $\displaystyle\frac{8}{32} \\ \end{minipage}}\)
If the numerator and denominator are divisible by the same number, then we can reduce the fraction :
\(\boxed{\\\begin{minipage}{4cm}Danette's\:pencils \\ $\displaystyle\frac{1}{4} $\\ \end{minipage}}\)
