4x + 10y
Hope it’s right
Best luck with your studying
Answer:
1. 24,000,000, i believe you divide, 300,000/80.
2. 4.065 seconds, i also believe you divide 5000m/1230.
You could use the function:
f(x)=30+2x
100=30+2x
In which lets say he rode 3 rides. Plug in 3 for x.
100=30+2(3)
Then Multiply
100=30+6
Then combine 30 and 6 to get 36.
Then you can subtract 36 from 100 to get
$64 left over.

- Find square root of 144 by factorisation method.

We can find the square root of 144 using the factorisation method. In this method, you need to factorise 144 first. Then, you'll get your answer in the form of prime factors. In this case, it's ⇨ 2 × 2 × 2 × 2 × 3 × 3.
__________________
To find the square root using factorisation, we need to group the same number in pairs. That is, 2 × 2 × 2 × 2 × 3 × 3 by grouping same numbers in pairs will become ⇨ (2, 2), (2, 2), (3, 3).
__________________
Now, you should take only 1 of the number from these groups. So, (2, 2), (2, 2), (3, 3) will change to ⇨ 2 × 2 × 3.
__________________
Finally, just multiply this set of numbers to find the square root of 144. 2 × 2 × 3 = 4 × 3 =
⇨ square root of 144.

Answer:
No
Explanation:
Cube A surface area is : 2x2x6 (because there are 6 faces) = 24
Cube B surface area is 4x4x6 = 96
The surface area of the cube B isn't the twice of cube A's surface area
Now the volumes :
Cube A volume is 2x2x2 = 8
Cube B volume is 4x4x4= 64
Cube B's volume isn't the twice of cube A's volume
