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.

An amount of $180 is shared among three people in the ratio x: y: z.

sammy [17]

Answer:

$110 and $30

Step-by-step explanation:

To solve this, we need to know the total share which is,

$4 + 11 + 3 = 18$

Then, you need to know the fraction of the share over the total, such that

$x = \frac{4}{18}$

$y = \frac{11}{18}$

$z = \frac{3}{18}$

So if to find how much that'll be of the $180 for the largest and smallest share,

Largest:

$\frac{11}{18} \times 180 = 110$

Smallest:

$\frac{3}{18} \times 180 = 30$

Alabama papas must average 80 on five test . Scores on the first four test were 81 73 84 and 76 what is the lowest score she can

Salsk061 [2.6K]

She has to score at least 86 on her fifth test.

Further explanation:

We will use the average formula to find the fifth value.

Given

$Average\ required=80\\x_1=81\\x_2=73\\x_3=84\\x_4=76\\x_5=?$

We have to find x5

The formula for average is:

$x=\frac{Sum\ of\ values}{Total\ number\ of\ values}\\Here,\\n=5\\So,\\x=\frac{x_1+x_2+x_3+x_4+x_5}{5}\\Putting\ values\\80=\frac{81+73+84+76+x_5}{5}$

$80*5=314+x_5\\400=314+x_5\\x_5=400-314\\x_5=86$

She has to score at least 86 on her fifth test.
