Answer:

x = 35

Step-by-step explanation:

Co interior angle sum to 180° , so

x + 30 + 3x + 10 = 180 , that is

4x + 40 = 180 ( subtract 40 from both sides )

4x = 140 ( divide both sides by 4 )

x = 35

Answer:

1385.28 m²

Step-by-step explanation:

apothem = √16² - 8² = √256 - 64 = √192 = 13.86

Base area = 3 x 16 x 13.86 = 665.28

6 side area = 3 x 16 x 15 = 720

surface area = 665.28 + 720 =1385.28

A can of soda is placed inside a cooler. As the soda cools, its temperature T (x) in degrees celsius is givien by the following

wel

Answer:

Initial 18 degrees Celsius

After 20 minutes, 5 degrees Celsius

Step-by-step explanation:

It’s initial temperature can be calculated as at the time when x = 0

When x = 0, the temperature is -6+24 = 18 degrees Celsius

This is because the exponent part equals 1 since anything raised in to the power of zero is one.

After twenty minutes,

T(x) = -6 +24e^-0.038(20)

T(x) = -6 + 11.224 = 5.224

And that is approximately 5 degrees Celsius to the nearest degree

Use the quadratic formula to solve the equation to the exact value or round to two decimal places.

lys-0071 [83]

First set everything to 0.
${x}^{2} + x - 5$
Giving you A= 1 , B= 1 and C= -5
Then input everything into the quadratic formula and either solve by hand or use a calculator.
Note exact values are found by hand, decimals are found using a calculator.
