______
c.865

how do I solve this and what are the answers for a. b. and c.

Answers

Answer:

a=0, b=7, c=3

Step-by-step explanation:

Addition

The following addition is shown, where a,b, and c are unknown:

 2.14a

+ 1.b25

-------------

  c.865

We'll determine the values of the unknown variables by following the rules of addition.

The last column shows a+5=5. Since a cannot be greater than 9, thus a must be 0.

a = 0

This sum produces no carry.

Now we have 4 + 2 = 6

This is already correct and no variable needs to be calculated

Now we have 1 + b = 8. This leads to b=8-1=7

b = 7

This sum produces no carry.

Finally: 2 + 1 = c. This implies that

c=3

Substituting in the addition:

 2.140

+ 1.725

-------------

:
Solve the quadratic equation

Rearranged equation
x2 - 10x + 24 = 0

This equation has two rational roots:
{x1, x2}={6, 4}


STEP
4
:
Check that the first solution is correct

Original equation

5 tons and 8 lbs is i believe the answer

Answer:

5 tons and 8 pounds

Step-by-step explanation:

1 ton is equal to 2000 pounds.

40 tons is equal to 80000 pounds (40*2000)

80000+64=80064

80064/8 = 10008

10008 is equal to 10000+8

10000/2000 = 5

5 tons and the leftover 8 is pounds

An object's temperature cools exponentially after it is removed from a furnace (hot oven). If its initial temperature is 730°C and it cools at a rate of 2.95% per minute, find the object's temperature after 18.0 minutes.

Answers

Answer:

The object's temperature after 18 minutes is of 426ºC.

Step-by-step explanation:

The temperature after t minutes is modeled by an exponential function, which has the following format:

[tex]T(t) = T(0)(1-r)^{t}[/tex]

In which T(0) is the initial temperature, and r is the cooling rate, as a decimal.

Its initial temperature is 730°C and it cools at a rate of 2.95% per minute

This means that [tex]T(0) = 730, r = 0.0295[/tex]. So

[tex]T(t) = T(0)(1-r)^{t}[/tex]

[tex]T(t) = 730(1-0.0295)^{t}[/tex]

[tex]T(t) = 730(0.9705)^{t}[/tex]

Find the object's temperature after 18.0 minutes.

This is [tex]T(18)[/tex]. So

[tex]T(t) = 730(0.9705)^{t}[/tex]

[tex]T(18) = 730(0.9705)^{18} = 426[/tex]

The object's temperature after 18 minutes is of 426ºC.

The required value of the object's temperature after 18.0 minutes is 425.83.

Given that,

An object's temperature cools exponentially after it is removed from a furnace (hot oven).

If its initial temperature is 730°C and it cools at a rate of 2.95% per minute,

We have to determine,

Find the object's temperature after 18.0 minutes.

According to the question,

The initial temperature is 730°C and it cools at a rate of 2.95% per minute,

The temperature after t minutes is modeled by an exponential function, which has the following format is,

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

Where T(0) is the initial temperature, and r is the cooling rate, as a decimal.

Then,

T(0) = 730°c and r = 2.95% = 0.0295

Substitute all the values in the equation,

[tex]= T(t) = T(0).(1-r)^t\\\\= T(t) = 730 \times (1-0.0295)^t[/tex]

Therefore,

The object's temperature after 18.0 minutes is,

[tex]= T(t) = T(0).(1-r)^t\\\\= T(18) = 730 \times (1-0.0295)^{18}\\\\= T(18) = 730 \times 0.5833\\\\ = T(18) = 425.8361[/tex]

Hence, The required value of the object's temperature after 18.0 minutes is 425.83.
