Answer:
50.24
Step-by-step explanation:
You will do
(area of a circle) x (hight)
Area of a circle = A
lets say 3.14 is pi
A = 3.14 x 2^2
A = 3.14 x 4
A = 12.56
Now
V = 12.56 x 4
V = 50.24
Answer:
1.333333... (only using (2,5) and (-4,-3)
Step-by-step explanation:
You do m=(y2-y1)/(x2-x1)
m=(-3-5)/(-4-2)=1.3333333...
9514 1404 393
Answer:
(x, y) = (34/5, -4/5) = (6.8, -0.8)
Step-by-step explanation:
Subtract the first equation from the second to eliminate x.
Substituting for y in the second equation, we can find x.
The solution is (x, y) = (34/5, -4/5) = (6.8, -0.8).
Answer:
B
Step-by-step explanation:
First calculate BD using sine ratio in Δ BCD and the exact value
sin60° = 
, thus
sin60° = 
= 
= 
= ( cross- multiply )
2BD = 12
( divide both sides by 2 )
BD = 6
-----------------------------------------------------------
Calculate AD using the tangent ratio in Δ ABD and the exact value
tan30° = 
, thus
tan30° = 
= 
= 
= ( cross- multiply )
AD = 6 ( divide both sides by )
AD = 6 → B
Answer:
25.19
Step-by-step explanation:
Change the percentage into a decimal. 30% is the same as saying 30/100.
This is 30 hundredths and in decimal form, it looks like this:
0.30 since 30/100 is the same as 3/10
To find out how much of a discount he gets, multiply 0.30 times 35.99.
0.30 x 35.99 = 10.797 which rounds up to 10.80.
This means he gets 10.80 off of the original price.
To find out what the new price is, subtract that from the original price.
35.99 - 10.80 = 25.19
