<em>$650</em>
- Step-by-step explanation:
<em>90% .............. $585</em>
<em>100% ............ $ x</em>
<em>x = 100×585/90</em>
<em>= 58500/90</em>
<em>= $650</em>
Answer:
B. A cow of 5 years is predicted to produce 5.5 more gallons per week.
Step-by-step explanation:
Let , where is the age of the dairy cow, measured in years, and is the predicted milk production, measured in gallons per week.
Besides, we consider and , such that , we define the difference between predicted milk productions () below:
(1)
If we know that and , then the difference between predicted milk productions is:
That is, a cow of 5 years is predicted to produce 5.5 more gallons per week than a cow of 10 years. Hence, the right answer is B.
Answer:
Step-by-step explanation:
With this word problem, we can model it into an equation which we can interpret to find values.
If we need to read 5 novels per month and n represents the amount of novels read in m months, we know that n will be the dependent variable (y) as it's a direct function of the number of months. This makes m the independent variable (x).
Since there are 5 novels a month, the equation will be 5 times the number of months equals the number of novels per month.
aka -
We can now substitute inside the equation with 11 months as m, and find the value of n.
Hope this helped!
As both lines and triangles have to have complete 180 degrees, we can deduce that the other angle by C is 130 degrees, as 180-50 is 130. Then, we add 130 to the other 35 degrees we have in the triangle, resulting in 165 degrees. From there, as we know that triangles must have 180 degrees altogether, we can find the missing angle by calculating 180-165, which results in 15.
Therefore, we know that the missing angle is 15 degrees.
3x-2 is parallel
-1/3-10 is perpendicular because negative reciprocal is always perpendicular
1/3+1 is neither
