PLEASE HELP!!! The formula F =9/5 C + 32 expresses Fahrenheit temperature in terms of Celsius temperature. Find the Celsius temp

mrs_skeptik [129]

Answer:

The Celsius temperature is 5° when the Fahrenheit temperature is 41°.

Step-by-step explanation:

Given that:

F = $\frac{9}{5}$ C + 32

Where,

F represents the temperature in Fahrenheit

C represents the temperature in Celsius

For calculating Celsius temperature from 41° Fahrenheit, we will put F=41 in given equation

$41=\frac{9}{5}C+32$

Subtracting 32 from both sides

$41-32=\frac{9}{5}C+32-32\\9=\frac{9}{5}C$

Multiplying both sides by 5/9

$\frac{5}{9}*9=\frac{5}{9}*\frac{9}{5}C\\5=C\\$

C = 5°

Hence,

The Celsius temperature is 5° when the Fahrenheit temperature is 41°.

A picture frame measures 18 inches by 24.5 inches. find how many square inches of glass the frame requires

Arisa [49]

The question is simply asking you to compute the area.

Area = Length * breadth.

Area = 18 inches * 24.5 inches = ------- square inches. Use your calculator.

So that would be your answer in square inches.

A steamer going downstream traveled the distance between two ports in 3 hours. The return trip took 3 hours 40 minutes. Find the

lapo4ka [179]

Answer:

1.8 mph

Step-by-step explanation:

Speed of the steamer in still water is 18 mph.

Speed of the current = x mph.

1. The steamer going downstream traveled the distance between two ports in 3 hours. Traveling downstream the current "helps" the steamer, then the speed is 18 + x mph.

The distance traveled downstream = 3(18 + x) miles.

2. The steamer going upstream traveled the distance between two ports in 3 hours 40 minutes that is $3\frac{2}{3}$ hours. Traveling upstream the current "interferes" the steamer, then the speed is 18 - x mph.

The distance traveled upstream $3\dfrac{2}{3}(18-x)$ miles.

3. The distances are the same, so

$3(18+x)=3\dfrac{2}{3}(18-x)$

Solve this equation:

$3(18+x)=\dfrac{11}{3}(18-x)\\ \\9(18+x)=11(18-x)\\ \\162+9x=198-11x\\ \\9x+11x=198-162\\ \\20x=36\\ \\x=1.8\ mph$

Need help on this Algebra 2

ElenaW [278]

All you have to do to solve this question is to plug in gx as any other number you would plug in to the f(x) to solve the equation.

So it would be

F(3x-8) = 3(3x-8)^2 - 5(3x-8) - 9

Then FOIL the terms in the binomial or the first term, then after expanding the first term, distribute the numbers into each term inside the bracket and then at the end gather like terms to simplify.
