Answer: Football = 35 children
<u>Step-by-step explanation:</u>
I created a Venn diagram and labeled it as follows:
Tennis only = x
Both Tennis & Football = y
<u>Football only </u>= <u>x + y </u>
Total children = x + y + x + y
42 = 2x + 2y
We are also given that y = 2x <em>(twice as many play both tennis & football as just play tennis)</em>
Now we have two equations and can use substitution to solve for x & y:
42 = 2x + 2y
y = 2x
42 = (y) + 2y
42 = 3y
14 = y
Now let's find x:
y = 2x
14 = 2x
7 = x
We are asked to find how many children play football.
Football = x + y
<u>Both Tennis & Football</u> =<u> y </u>
Total Football = x + 2y
= 7 + 2(14)
= 7 + 28
= 35
Answer:
The volume of platform
= 11 ft³
Step-by-step explanation:
The height of the Platforms are
The food prep area = 5 ft
Storage shelf = 6 ft
Side of rectangle = b width of platform = d
Therefore area of platform = b·d
Volume of the food prep area platform = Area × height = 5 b·d ft³
Volume of the storage shelf platform = Area × height of storage shelf platform = 6 b·d ft³
Therefore the total volume = Volume of food storage platform + volume of storage shelf platform = 5 b·d ft³ + 6·b·d ft³ = 11·b·d ft³
Answer:
Over 2 oz. Class A-II felony
Step-by-step explanation:
One would need to carefully weigh the material.*
0.06 kg ≈ 2.12 oz
Note that .06 kg is 1 significant figure, so this rounds to 2 oz (1 significant figure). Given the precision of the reported weight, there is insufficient precision to say the amount is actually over 2 oz.
__
If you take the numbers at face value, the suspect is in possession of over 2 oz, so will be charged with a Class A-II felony.
_____
* 2.00 ounces translates to about 0.0567 kg, which rounds to 0.06 kg.
A) set x as the number of cameras
18x=9x+1800
9x=1800
x=200
b) i'm assuming it's increasing production from my answer in a, so the profit would be 18(250)-(9*250+1800)=4500-4050=450
