Jeremiah is saving money from a tutoring job.After the first three weeks,he saved $135.Assume the situation is proportional.Use

Zina [12379]

To find Jeremiah's savings after eight weeks, first divide 135 by 3 to find the weekly savings amount, which gives you 45. Then, multiply 45 by 8, resulting in a total savings of $360.

Micah deposits C dollars in a bank. The deposited amount earns an annual interest rate of r% and becomes D dollars in t years ac

PIT_PIT [12445]

Answer:

$t = \frac{100}{r} [\frac{D}{C} - 1]$

Step-by-step explanation:

Let’s consider that the amount deposited, C dollars, generates r% simple interest each year.

After a span of t years, the value of the deposited C dollars reaches D dollars; our task now is to formulate a relationship using these variables to find t.

We can express this relationship through the simple interest formula:

$D = C(1 + \frac{t\times r}{100})$

⇒ $1 + \frac{t \times r}{100} = \frac{D}{C}$

⇒ $\frac{t \times r}{100} = \frac{D}{C} - 1$

⇒ $t = \frac{100}{r} [\frac{D}{C} - 1]$

Thus, this yields the formula for t. (Answer)

Trains A and B, 200 km apart on the same straight track, travel at speeds of 50 km/hr and 65 km/hr respectively. At the end of 1

Leona [12618]

Answer:

Ok, la distancia inicial entre los trenes es de 200 km:

IPa(0s) - P(0s)I = 200 km.

donde Pa representa la ubicación del tren A y Pb representa la ubicación del tren B.

La velocidad del tren A es:

Sa = 50 km/h

Sb = 65 km/h

Recuerda la relación:

Distancia = Velocidad * tiempo.

<pAsí, en una hora, la distancia recorrida por el tren A es:

Distancia = 50 km/h * 1 h = 50 km

<pLa distancia recorrida por el tren B es:

distancia = 65 km/h * 1 h = 65 km.

<pSi al inicio el tren A está 200 km adelante del tren B, entonces tenemos:

Pa - Pb = (Pa(0s) + 50 km) - (Pb(0s) + 65 km)

= (Pa(0s) - Pb(0s)) + (50 km - 65 km) = 200 km - 15 km = 185 km.

<pAhora, si el tren B estaba 200 km por delante del tren A, tenemos:

Pb - Pa = (Pb(0s) + 65 km) - (Pa(0s) - 50 km) =

(Pb(0s) - Pa(0s)) + (65 km - 50 km) = 200 km + 15 km = 215 km
