The temperature in degrees Celsius can be determined using the expression 5 9 (F – 32) where F is the temperature in degrees Fah
Norma-Jean [14]

Answer:

The temperature on Celsius scale for 86 ºF is 30 ºC.

Step-by-step explanation:

Both degrees Celsius and Fahrenheit are relative scales of temperature. The relationship between degrees Fahrenheit and degrees Celsius is summarized by the equation below:

T_{C} = \frac{5}{9}\cdot (T_{F}-32) (1)

Where:

T_{F} - Temperature, measured in degrees Fahrenheit.

T_{C} - Temperature, measured in degrees Celsius.

If we know that T_{F} = 86\,^{\circ}F, then its equivalent temperature on Celsius scale is:

T_{C} = \frac{5}{9}\cdot (86-32)

T_{C} = 30\,^{\circ}C

The temperature on Celsius scale for 86 ºF is 30 ºC.

In the equation x2 +10x + 24 = ( x + a) ( x + b), b is an integer. Find algebraically all possible values of b.
kramer
Multiply
(x+a)(x+b) = x^2 + bx + ax + ab
looking at; x^2 + 10x + 24
can you see that

ab = 24
bx + ax = 10x
then
a + b = 10

use substitution: a = 10 - b

(10-b)b = 24
10b - b^2 = 24
-b^2 + 10b -24 = 0
now find the values for b using the quadratic equation. I'm on my phone so you'll have to plug the numbers in. let me know if you have any questions.

A courtyard has the shape of a rectangle 45 ft and 28 ft wide. How long is a sidewalk from one corner diagonally to the opposite
sp2606 [1]

Answer:

53

Step-by-step explanation:

We use the pythagorean theorem, a^2 + b^2 = c^2. We can fill a and b for 45 and 28. 45^2 is 2025, and 28^2 is 784. Adding them up gives us 2809. The square root of 2809 is 53.
