Answer:
drone is 60km/h bird 40km/h
Step-by-step explanation:
--------------------------------------------------------------------
Ratio Given
--------------------------------------------------------------------
Apple : Strawberry
4 : 5
--------------------------------------------------------------------
Find difference in parts
--------------------------------------------------------------------
5 - 4 = 1
--------------------------------------------------------------------
Find Number of strawberry cakes
--------------------------------------------------------------------
1 part = 24 cakes
5 parts = 24 x 5 = 120
--------------------------------------------------------------------
Find number of apple cakes
--------------------------------------------------------------------
1 part = 24 cakes
4 parts = 24 x 4 = 96
--------------------------------------------------------------------
Total number of cakes
--------------------------------------------------------------------
120 + 96 + 144 = 360
--------------------------------------------------------------------
Percentage of cranberry cakes
--------------------------------------------------------------------
144/360 x 100 = 40%
--------------------------------------------------------------------
Answer: 40% of the cakes are cranberry cakes
--------------------------------------------------------------------
Area of a circle = πr^2
Area of a sector with angle x° = (x/360) πr^2
For the smaller sector,
x = 30°
r = 6 in
Required area of sector = (30/360) × π × 6^2 = 9.424 in^2
To the nearest hundreth, Area = 9.42 in^2
Answer:
In your equations, there is only one variable you're using: y. I do not know what you mean by 2 variables, but probably you copied the wrong equations.
......Anyways......
To solve it, you must know that the sum of all 3 angles of a triangle is 180°.
To set up the equation, add all three angle measures on one side of the equation, and then 180 on the other side. It should be like this:
(6y+1)+(4y-7)+(9y+3) = 180
Now that you're done with the set-up, I assume you know what to do next. We can't always do the work for you. ^_~
> Add up the measures of each angle.
> Isolate the equation with only variable on one side and only number on the other side.
> Substitute each variable y for each angle measure and solve it.
Hope this helps a lot. ^_^
