The rate of speed is 5 miles per hour

0: 20 + 5

1: 25 + 5

2: 30 + 5

3: 35 + 5

4: 40

Step-by-step explanation:

Answer:

The rate of speed is 5 miles per hour.

Step-by-step explanation:

Choose two lines of data as two ordered pairs:

(0, 20) and (4, 40)

The rate of speed is the same as the slope of the line that passes through those two points.

slope = (difference in y)/(difference in x)

slope = (40 - 20)/(4 - 0) = 20/4 = 5

The slope is 5, so the speed is 5 mph

Answer: The rate of speed is 5 miles per hour.

Renee bought 7 potatoes at the supermarket. The shortest diameter of each, in centimeters, is shown below

Answers

Answer:

2, 3, 4

Step-by-step explanation:

Renee bought 7 potatoes at the supermarket. The shortest diameter of each,  

in centimeters, is shown below.

2, 3, 4, 4, 6, 6, 7

After Renee used one potato to make dinner, the median diameter of the remaining  potatoes was 5 centimeters. Which of these could be the diameter, in centimeters,  of the potato Reneetsed?

Solution:

The median of a group of numbers is the middle number when the group of numbers are arranged in a sorted manner, either ascending or descending.

The median of an even group of numbers, is gotten by taken the average of the two innermost numbers.

Given that the diameter of the potato as:

2, 3, 4, 4, 6, 6, 7

Given that after removing one potato, the median of the remaining  potatoes was 5 centimeters.

After removing one potato, the remaining would just be 6. 6 is an even number, hence the median would be the average of the 2 middle numbers.

To get 5 cm, it has to be the average between 4 and 6. This is only possible when a potato of diameter 2,3 or 4 is removed.

If potato with diameter 2 is removed, the remaining is 3, 4, 4, 6, 6, 7.

Median = (4 + 6) / 2 = 5

If potato with diameter 3 is removed, the remaining is 2, 4, 4, 6, 6, 7.

Median = (4 + 6) / 2 = 5

If potato with diameter 4 is removed, the remaining is 2, 3, 4, 6, 6, 7.

Median = (4 + 6) / 2 = 5

Answer/Step-by-step explanation:

✔️Find BC:

Reference angle = 50°

Opposite = BC

Adjacent = 5 cm

Based on trigonometric ratio, thus:

Tan 50 = BC/5

Multiply both sides by 5

BC = 5 × tan 50

BC = 5.96 cm (to 3 s.f)

✔️Find x:

Reference angle = 38°

Opp = x

Adj = BC = 5.96 cm

Based in trigonometric ratio, thus:

Tan 38 = x/5.96

Multiply both sides by 5.96

x = 5.96 × tan 38

X = 4.66 (3 s.f)

what is -60 ÷_______ = 12

Answers

Answer:

5 is the answer.

60÷5=12 as 12×5=60

Answer:

-5

Step-by-step explanation:

The equation, -60 ÷ ____ = 12 can be easily reversed to help us find the missing divisor.

To find the missing divisor, we can rewrite the equation as -60 ÷ 12 = ___.

This way, we can find what the quotient (the divisor of the original equation).

-60 ÷ 12 is equal to -5, so therefore the divisor of -60 ÷ ___ = 12 is -5!

So the finished equation would look like this: -60 ÷ -5 = 12!

(To check your work, multiply -5 by 12 to see if it equals -60 :D)

Cuatro meses después que se detuviera la publicidad, una compañia fabricante notifica que sus ventas han cai­do de 100.000 unidades por mes a 80.000. Si las ventas siguen un patron de decrecimiento exponencial, cuantas unidades habra despues de los siguientes dos meses?

Answers

Answer:

51,200 unidades

Step-by-step explanation:

Paso 1

Calculamos el porcentaje de disminución

= 100000 - 80000/100000 × 100

= 20000/100000 × 100

= 20%

Por lo tanto, el porcentaje de disminución cada mes = 20%

Paso 2

La fórmula de la disminución exponencial

y = a (1 - r) ^ t

a = 80.000

r = 20% = 0,2

t = tiempo en meses = 2

y = 80000 (1 - 0,2) ^ 2

y = 51.200 unidades

Usando una función exponencial, se encuentra que habra 71.554 unidades despues de los siguientes dos meses.

Una función exponencial decreciente tiene el siguiente formato:

[tex]A(t) = A(0)(1 - r)^t[/tex]

En que:

A(0) es la cuantia inicial.r es la tasa de desintegración.

En este problema:

Inicialmente, 100000 unidades por mes, o sea, [tex]A(0) = 100000[/tex].Cuatro meses después, 80000 unidades por mes, o sea, cuando [tex]t = 4, A(t) = 80000[/tex], e esto es usado para encontrar r.

[tex]A(t) = A(0)(1 - r)^t[/tex]

[tex]80000 = 100000(1 - r)^4[/tex]

[tex](1 - r)^4 = 0.8[/tex]

[tex]\sqrt[4]{(1 - r)^4} = \sqrt[4]{0.8}[/tex]

[tex]1 - r = 0.945742[/tex]

Por eso:

[tex]A(t) = A(0)(1 - r)^t[/tex]

[tex]A(t) = 100000(0.945742)^t[/tex]

Apos el siguinte dos meses, hay el mes 6, por eso:

[tex]A(6) = 100000(0.945742)^6 = 71554[/tex]

Habra 71.554 unidades despues de los siguientes dos meses.

Step 4: [tex]z*4 = 4z[/tex]

Step-by-step explanation:

Given

[tex]z+z+z+z = 4z[/tex]

Required

Match the steps with equivalent properties

Step 1: Multiplicative Identity Property

This states that:

[tex]x = 1 * x[/tex]

So, the expression becomes:

[tex]z*1+z*1+z*1+z*1=[/tex]

Step 2: Distributive Property

This states that:

[tex]ab + bc = b(a+c)[/tex]

So, the expression becomes

[tex]z*1+z*1+z*1+z*1=[/tex]

[tex]z(1+1+1+1)=[/tex]

Step 3: Addition

Here, we simply add the expressions in the bracket

[tex]z(1+1+1+1)=[/tex]

[tex]z(4) =[/tex]

[tex]z*4=[/tex]

Step 4: Commutative Property of Multiplication

This states that:

[tex]ab=ba[/tex]

So, we have:

[tex]z*4=[/tex]

[tex]z*4 = 4*z[/tex]

[tex]z*4 = 4z[/tex]
