Divide 3/4 by 5/8
= 6/8 / 5/8 = 6/8 * 8/5 = 6/5
Unit rate is 1 to 6/5 = = 1 to 1.2
Answer:
The temperature changed by 
overnight.
The temperature changed by 
overnight each hour.
Step-by-step explanation:
Given that:
Temperature at 7 PM last night = 
Temperature at 7 AM the next morning = 
a. The change in temperature from 7 PM to 8 AM = Temperature at 7 AM - Temperature at 7 PM
Negative sign indicates that the temperature has decreased.
b. Change in temperature each hour:
Divide the Change in temperature with the number of hours.
Negative sign indicates that the temperature has decreased.
Answer:
The answer is A. ( x-3/x-6 x X^3 + 5/x+1 ) is rational because it is a product of rational expressions since rational expressions are closed under multiplication.
Step-by-step explanation:
The 2 smaller angles are x and 2x - 6 so we have:-
2x - 6 + x = 90
3x = 96
x = 32 and 2x - 6 = 64 - 6 = 58
2 smaller angles are 36 and 58 degrees.
Answer:
3. 0
4. n = -2
Step-by-step explanation:
I haven't taken pre-calc but this looks a lot like algebra.
For #3, just plug in -2 for the x values, so:
x^2 + 4x +4
(-2)^2 + 4(-2) + 4
= 4 - 8 + 4
= 0
For #4, move the variables to one side and solve( im not sure what the pi is for tho, or is that a n?):
5n + 6 = -3n - 10
add 3n to both sides
8n + 6 = -10
subtract 6 from both sides
8n = -16
divide both sides by 8
n = -2
