Your answer is -4.23 degrees fahrenheit.
To get that answer you must take you starting temperature, 9.17, and your decreased amount of temperature, 13.4, and subtract them.
So, you have 9.17 - 13.4 = -4.23
You can not reverse the numbers or it will give you the wrong answer.
the answer is 0.921.

Answer:
sin(x) = cos(90°-x)
Step-by-step explanation:
Looking at the graphs of sin(x) and cos(x), you can see that the peaks of the graph are separated by a value of pi/2. If you convert that value into degrees, then the two graphs are separated by 90°. Another way of thinking is from the unit circle. sin(x) = 1 at 90°, and cos(x)=1 at 0°. The difference is still 90°
The inequivalent one is c. 9/36
Answer:
B. 128 square centimeters
Step-by-step explanation:
So first make the top triangle part its own figure. By using information provided you can figure out the height of the triangle would be 3 by subtracting 11 from 14. Take 3 multiply it by the base and then 1/2 to get 18. Then find the area of the rectangle which would be 10 times 11 which is 110. Add the areas of the two parts, 110 and 18 to get 128.
