Step-by-step explanation:
5/ 1/3=1.6x2=3.2
Answer:
C
Step-by-step explanation:
We know it's direct variation using the direct variation equation.
Where k is the constant.
Since 7 times x is the y values, 
Now we can substitute 7 into k of the direct variation equation.
Answer:
120 cm²
Step-by-step explanation:
From the question;
- Length is 12 cm
- Width is 10 cm
We are required to determine the area of the cross section;
- Note that the cross section is the plane of a solid that remains constant through the solid.
- In this case, the cross section is a rectangle whose dimensions are 12 cm by 10 cm.
But Area of a rectangle = Length × Width
Therefore;
Area of cross section = 12 cm × 10 cm
= 120 cm²
Thus, area of the cross section is 120 cm²
An equation whose variables are polar coordinates is called a polar equation. These equation are characterized by an r as a function an angle. Polar equations can be written in rectangular coordinates by certain relationships. An example of a polar equation would be r = 2sin∅.
Answer:
D. 11n + 12
Step-by-step explanation:
You can simplify the 4n + 7n to be 11n by adding them together.
This means the answer is 11n + 12.
