Answer 1

Answer:

Blank 1: 28

Blank 2: 42

Blank 3: 22

Answer: It will take 7 sessions.

Step-by-step explanation:

We already know the 3 blanks from the equation 28x = 42 + 22x

Now to find the answer.

28x = 42 + 22x

Subtract 22x from both sides. This cancels the +22x.

28x - 22x = 42

Subtract 22x from 28x to get 6x

6x = 42

Divide both sides by 6. This undoes the multiplication by 6.

x = 42/6

Divide 42 by 6 to get 7.

x = 7

It will take 7 sessions for the costs to match.

A school has 320 girls and 250 boys the probability of a girl being left handed is 0.2 the probability of a boy being left handed is 0.1 estimate the amount of left handed people there are in the school

Answers

320 girls & 250 boys

0.2 probability 0.1 probability

Answer

89% of the people are left handed

Step-by-Step Explanation

To find this you have to first do 320 x 0.2

320 x 0.2= 64

To find it for boys you have to do 250 x 0.1.

250 x 0.1= 25

A $40,000 car depreciates in value about 18% per year for the life of the car. Determine the value of the car after 7,8, and 9 years. What is the rate of decay?

Answers

Answer:

Value after:

7 years = $9971.42

8 years = $8176.56

9 years = $6704.78

Rate of decay = 18%

Step-by-step explanation:

A $40,000 car depreciates in value about 18% per year for the life of the car.

Determine the value of the car after 7,8, and 9 years. What is the rate of decay?

The formula for Depreciation is

FV = PV( 1 - r)^t

Where

FV = Future value

PV = Present value = $40,000

r = Depreciation rate = 18% = 0.18

t = time in years

a) After 7 years

$40,000 (1 - 0.18)⁷

= $9971.4188227

= $9971.42

b) After 8 years

$40,000 (1 - 0.18)⁸

= $8176.5634346

= $8176.56

c) After 9 years

$40,000 (1 - 0.18)⁹

= $6704.7820164

≈ $6704.78

= $9971.42

The Rate of decay = 18%

Calcula la longitud en YARDAS de
un trayecto A que mide 100 metros
y la longitud en
YARDAS de un trayecto B que mide 18.50

Answers

Answer:

Las longitudes solicitadas en yardas son:

Trayecto A = 109.361 yardas.Trayecto B = 20.231785 yardas.

Step-by-step explanation:

Para hacer la conversión de unidades que requieres en el ejercicio, debes saber que:

1 metro = 1.09361 yardas

Con ese factor de conversión tú puedes hacer reglas de tres para calcular las medidas que requieres. En el caso del trayecto A:

Si:

1 metro = 1.09361 yardas100 metros = X

Entonces:

[tex]x=\frac{100m *1.09361yardas}{1m}[/tex]

Cancelamos metros y obtenemos:

x = 100 * 1.09361 yardasx = 109.361 yardas

En este caso, el trayecto A en yardas corresponde a 109.361 yardas. El mismo procedimiento puede aplicarse para el trayecto B:

Si:

1 metro = 1.09361 yardas18.50 metros = X

Entonces:

[tex]x = \frac{18.50m*1.09361yardas}{1m}[/tex]

Cuando se cancelan los metros se obtiene:

x = 18.50 * 1.09361 yardasx = 20.231785 yardas

Así, el trayecto B en yardas corresponde a 20.231785 yardas.

X, Y and Z are three points on a map. Y is 75km and on a bearing of 200° from X. Z is on a bearing of 150°, from Y. Z is due south of X. Calculate the distance between X and Z rounded to 1 DP.

Answers

Answer:

The distance between X and Z is approximately 114.9 km

Step-by-step explanation:

The given parameters are;

The distance of Y from X = 75 km

The bearing of Y from X = 200°

The bearing of Z from Y = 150°

The bearing of Z from X = 180°

In triangle XYZ, we have;

∠YZX = 180° - (130° + 20°) = 30°

By sine rule, we have;

(75 km)/sin(30°) = XZ/(sin(130°))

XZ = sin(130°) × (75 km)/sin(30°) ≈ 114.9 km

The distance between X and Z ≈ 114.9 km. to one decimal place.
