The formula F=9/5C+32 converts temperatures from Celsius C to Fahrenheit F. A. Solve the formula for C b. The boiling point of w
liraira [26]

Answer:

(a) \therefore C=\frac59(F-32)

(b)The boiling point of water in Celsius scale is 100°C.

(c)The setting in Celsius scale is 26.7°C.

Step-by-step explanation:

Given that,the formula is

F=\frac95 C+32......(1)

(a)

Given that,

F=\frac95 C+32

\Rightarrow F-32=\frac95 C+32-32     [ subtracting 32  from both sides]

\Rightarrow F-32=\frac95 C

\Rightarrow \frac95 C=F-32

\Rightarrow C=\frac59(F-32) ......(2)         [Multiplying \frac59  ]

\therefore C=\frac59(F-32)

(b)

Given that, the boiling point of water is 212°F.

Putting F=212 in equation (2)

\therefore C=\frac59(212-32)

\Rightarrow C=\frac59\times 180

\Rightarrow C=5\times 20

\Rightarrow C=100

The boiling point of water is 100°C.

(c)

Given that, a house thermostat is set at 80 degree.

Putting F=80 in equation (2)

\therefore C=\frac59(80-32)

\Rightarrow C=\frac59\times 48

\Rightarrow C\approx26.7

The setting in Celsius scale is 26.7°C.

Q # 15 I need help please to resolve
kow [346]

The sequence is

740, 707.60,675.20,642.80,...

Here first term is 740, and common difference, d is

707.60-740 = -32.40

Now we use the formula of nth term, which is

a_{n} = a+(n-1)d

Substituting the values of a,n and d, we will get

=740+(n-1)(-32.40), 23 months

Correct option is the second option .
