(4x – 7)(16x^2 + 28x + 49) is equivalen to 64x3 - 343!
Answer:
44 degrees
Step-by-step explanation:
Since MN is a tangent, it forms a right angle wheng it intersects line MP since MP is the diameter. So, 90+46 is 136 and since there are 180 degrees in a traingle, 180-136 is 44.
Hope this is helpful! :)
Answer:
<u>y = x - 1/5</u>
Step-by-step explanation:
x - y = 1/5
5x - 5y = 1
5y = 5x - 1
<u>y = x - 1/5</u>
Answer:
The volume of the cone is 75.36 cm³
Step-by-step explanation:
The rule of the volume of a cone is V = 
π r² h, where
- r is the length of the radius of its base
- h is the height of the cone
In the given figure
∵ The length of the radius of the cone is 3 cm
∴ r = 3 cm
∵ The length of the height of the cone is 8 cm
∴ h = 8 cm
→ Substitute the values of r and h in the rule of the volume above
∵ π ≅ 3.14
∵ V = (3.14)(3)²(8)
∴ V = 75.36 cm³
∴ The volume of the cone is 75.36 cm³
For finding percents, I use a method called FOO
which is final-original÷original
the original is the first number and the final is the second
After FOO you must multiply by 100 to make it a percent
The equation is as followed:
225-75÷75×100
The answer is 125%
