Answer:
Step-by-step explanation:
A car leave P and drives 3km North to Q. From Q it's drives 15km on a bearing North 45degree East to R. Find the distance and bearing of R from P
Let x or y be 0
4x-2y=5
4(0)-2y=5
-2y=5
Divide -2 and 5 by -2.
y=-2.5
4x-2y=5
4x-2(0)=5
4x=5
Divide 4 and 5 by 4.
x=1.25
I did not check my math, feel free to correct me.
Answer:
adding 2 to each number
Step-by-step explanation:
7 +2 = 9 + 2 = 11
Angle a is directly opposite from a 40 degree angle, so a=40. Then we can find b since the sum of the angles of all triangles is 180 and there is a right angle in there along with angle a:
Last, to find c we just notice that it is supplementary with an angle of measure 65, so:
So our angles are a=40, b=50, c=115.
Given:
volume of larger cone : 8000 m³
radius of larger cone: 5 m
radius of smaller cone: 2 m
volume of smaller cone: ?
Find the volume of the smaller cone using the ratio of the volumes.
a / b = c / d where ad = bc
5m / 8000 m³ = 2 m / x
5m * x = 8000 m³ * 2m
5m * x = 16000 m⁴
x = 16000 m⁴ / 5m
x = 3200 m³
