Answer:

T(m) = (140 - 5m)

Step-by-step explanation:

Given that :

Initial temperature, a = 140 F

Rate of decrease = 5 F per minute

Given a certain Number of minutes, m

Temperature, T after m minutes ;

Using the formula :

Final temperature = Initial temperature - 5*number of minutes)

T(m) = (140 - 5m)

Given that ; m = 10

T(10) = 140 - 5(10)

T(10) = 140 - 50

T(10) = 90 F

Answer:

Explanation:

Write an equation to solve the problem.

Area of rectangle = L(w)

Assuming that the width measures x meters, the length measures x + 5 meters.

500 = x(x + 5)

500 =

x

2

+ 5x

0 =

x

2

+ 5x - 500

As you may already know, a trinomial of the form

a

x

2

+ bx + c, a = 1, you must find 2 numbers that multiply to c and that add to b. Two numbers that multiply to -500 and add to +5 are +25 and -20

0 = (x + 25)(x - 20)

x = -25 and 20

Since a negative length is impossible, the width mesures 20 meters and the length measures 25 meters.

Practice exercises:

Step-by-step explanation:

Answer:

? = 20

Step-by-step explanation:

Since the figures are similar then the ratio of corresponding sides are equal, that is

[tex]\frac{12}{15}[/tex] = [tex]\frac{?}{25}[/tex] ( cross- multiply )

15 ? = 300 ( divide both sides by 15 )

? = 20

Answer: The pool table is rectangle, so we assume it with Length a feet and b feet, respectively.

So area=a*b=24 square feet

perimeter=2(a+b)= 22 feet

then we calculate with this two equation to get a and b.

because  a+b=11, then a=11-b, we put this into a * b=24

then we get (11-b)*b=24,  

b^2-11b+24=0

b=3 feet or b=8 feet

then we can get a by a=11-b, if b=3, then a=8; if b=8, then a=3.

so the dimension of the pool table is 3 feet and 8 feet

Step-by-step explanation:

Answer:

Point R: (-2,0)

Point A: (-6,-2)

Point N: (-1,-3)

Step-by-step explanation:

Reflecting a shape across the y-axis means that the y value of the coordinate of the points would reverse its sign, meaning for eg a negative number would turn into a positive one or a positive would turn into a negative.

So in this case, point R would stay the same because it's on the y-axis but the two points A and N would change. Point A is (-6,2) so if we change the y coordinate we would get (-6,-2) and point N is (-1,3) so it would become (-1,-3). Therefore the answer is:

Point R: (-2,0)

Point A: (-6,-2)

Point N: (-1,-3)

Using the information displayed on the two-way table, the true statement ls "About 1/3 of his classmates live near a pool and do not own a bike".

From the distribution table :

There are many of his classmates who own a bike and also live near a pool and vice versa.

The number of his classmates who live near a pool and do not own a bike is 10

Total number of class mates = 30

Fraction who do live near a pool and do not own a bike can be calculated thus :

Hence, about 1/3 of the students live near a pool and do not own a bike.

Answer:

Step-by-step explanation:

The area of ​​a rectangle is 600 cm2. Calculate the dimensions of the rectangle knowing that its perimeter is 100 meters.

The formula for the area of a triangle =

Length × Width = 600 cm²

LW = 600

W = 600/L

Perimeter of a rectangle = 2L + 2W = 100m

2L + 2W = 100

we substitute

2L + 2(600/L ) = 100

2L + 1200/L = 100

Multiple all through by L

2L² + 1200 = 100L

2L² - 100L + 1200 = 0

We factorise

2L² - 60L - 40L + 1200= 0

Las dimensiones del rectángulo serían:

Longitud = 30m

Ancho = 20m

Dado que,

Área del rectángulo = 600[tex]m^2[/tex]

Sabemos,

Área del rectángulo = l × b

entonces,

l × b = 600[tex]m^2[/tex]  

⇒ l = 600/b ...(i)

A continuación, tenemos,

Perímetro = 100m

Lo sabemos,

Perímetro del rectángulo = 2(l + b)

⇒ 100 = 2(l + b)

al poner (i), tenemos,

⇒ [tex]100/2 = (600/b + b)[/tex]

⇒ [tex](600 + b^2)/b = 50[/tex]

al resolver esto, obtenemos;

[tex]b^2 + 600 = 50b[/tex]

⇒ [tex]b^2 - 50b + 600 = 0[/tex]

⇒ [tex]b^2 - 30b - 20b + 600= 0[/tex]

⇒ [tex]b(b - 30) - 20(b - 30) = 0[/tex]

⇒ [tex](b - 20) (b - 30)[/tex]

∵ [tex]b = 20 m, b = 30m[/tex]

poniendo el valor de b, podemos encontrar:

[tex]l = 600/20[/tex]

∵ [tex]l = 30 m[/tex]

∵ Longitud = 30m

Ancho = 20m

Answer:

Primero Pedro va al río con ambos recipientes.

Pedro llena el cubo de 5 litros.

Ahora (usando el agua del cubo de 5 litros) él puede llenar el pote de 3 litros.

De esta forma ahora tendrá:

3 litros de agua en el pote de 3 litros.

5 - 3 = 2 litros de agua en el cubo de 5 litros.

Ahora pedro debe vaciar el pote de 3 litros.

Ahora pedro pone los dos litros de agua que quedaban en el cubo grande en el pote de 3 litros.

En este momento tenemos:

2 litros de agua en el pote de 3 litros.

0 litros de agua en el cubo de 5 litros.

Ahora pedro deberá volver a llenar el cubo de 5 litros.

Con este cubo lleno, el pondrá agua en el pote de 3 litros hasta que se llene. Pero el pote de 3 litros ya tiene 2 litros, es decir, Pedro solo debe usar un litro del cubo para llenarlo.

Una vez pedro usa un litro del cubo, el agua restante en este será:

5 litros - 1 litro = 4 litros.

En este momento pedro tiene 4 litros de agua en el cubo de 5 litros.

Entonces puede vaciar el pote de 3 litros y regresar con exactamente 4 litros.

saving per week = $25

Hence the expression for the total savings after the 6 weeks is given as

y= mx+c

where

m= $25

x= 6 weeks

c= $90

substitute

y=25*6+90

y= 150+60

y= $210

Hence the total amount after 6 weeks is $210
