Step-by-step explanation:
Number of shells she had in the begining = 40
Number of shells collected in the morning and at noon = 6 + 3 = 9
Now the number of shell at the end = 40 + 9 = 49
Icreased shells = 49 - 40 = 90

Answer:
y = 2/5 x + 4/5
Step-by-step explanation:
First, we find the slpe of the line that is shown.
We go from point (-2, 2) to (0, -3).
We go 5 down, or a rise of -5.
Then we go 2 right, or a run of 2.
slope = m = -5/2
The perpendicular line has slope 2/5.
y = (2/5)x + b
2 = (2/5)(3) + b
10/5 = 6/5 + b
b = 4/5
y = 2/5 x + 4/5

Fernando compró un videojuego y sabe que el valor depreciado de este es de $600 luego de 12
meses de su compra y de $480 al término de 18 meses. Si el valor del sistema varía linealmente
con el tiempo, determina:
a) La ecuación que expresa la relación del valor del videojuego con su tiempo de uso.
b) El valor del videojuego cuando era nuevo.
ayudenme profavor
Usando una ecuación lineal, se encuentra que:
a) La ecuación es y = -20x + 840.
b) El valor del videojuego cuando era nuevo era de $840.
¿Qué es una función lineal?Una función lineal es modelada por:
y = mx + b
En el cual:
m es la pendiente, que es la tasa de cambio, es decir, cuánto cambia y cuando x cambia en 1.b es la intersección con y, que es el valor de y cuando x = 0, y también se puede interpretar como el valor inicial de la función.En este problema, el valor depreció $120 en 6 meses, por lo tanto la pendiente es dada por:
m = -120/6 = -20.
O sea:
y = -20x + b
Al longo de 12 meses, el valor deprecio 12 x 20 = $240. Por lo tanto, el valor inicial es dado por:
b = 600 + 240 = $840.
Y la ecuación es dada por:
y = -20x + 840.

Solve this linear equation 2.6(.5.5-12.4=127.92
Answer:
First we must distribute the 2.6 to everything inside the ()
The new equation would then be 14.3p-32.24 = 127.92
Then you would add a -32.24 to each side of the equal sign, so that the 32.34 would become a zero pair on the right side of the equal sign and cancel.
The new equation would then be 14.3p = 160.16
Then you divide each side of the = by 14.3, that way the p becomes isolated. 14.3p/14.3 = 160.16/14.3
Then you're left with p=11.2

Answer:
592 in²
Step-by-step explanation:
The surface area is the sum of the areas of the rectangles shown in the figure.
__
The light blue central rectangle is 12 in wide and a total of 36 in tall. Its surface area is ...
A = LW = (12 in)(36 in) = 432 in²
The two identical darker blue rectangles on the sides are each 8 in by 10 in, so their total area is ...
A = 2(LW) = 2(8 in)(10 in) = 160 in²
The total surface area of the figure is (432 +160) in² = 592 in².

Find the volume of a right circular cone that has a height of 3.5 ft and a base
with a diameter of 11.9 ft.
Step-by-step explanation:
the volume of a cone is
base area × height / 3
and the case area is a circle, so we get
pi×r²×h/3
with e being the radius (half of the diameter), and h being the height.
therefore
pi×(11.9/2)²×3.5/3 = pi×(5.95)²×3.5/3 = 41.30291667... ft³

There is a bag filled with 4 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 blues?
Answer:
16/81
Step-by-step explanation:
Given
In the bag, there are : 4 blue and 5 red marblesProbability of blue (1st time)
P(1) = Total blue / Total marblesP(1) = 4 / (4 + 5)P(1) = 4/9Probability of blue (2nd time)
P(2) = Total blue / Total MarblesIt states it is replaced hence it is of the same constitution as the beginningP(2) = 4/9Probability of blue (both times)
P = P(1) x P(2)P = 4/9 x 4/9P = 16/81
