Answer:
Step-by-step explanation:
There's 24 students so I would do 5 × 24 which equals 120 so 420 - 120 is 300. Then 2 × 24 is 48. Now 300-48 is 252. They would have $252 left.
3p+4s=68 and 3p+7s=92 we can rearrange equation 1 to let 's' be the subject : s=(68-3p)/4. We can then sub this into equation 2 so that there is only one unknown: 3p+7(68-3p)/4=92. Then takeaway p from both sides: 7(68-3p)/4=92-3p. Then multiply by 4: 7(68-3p)= 4(92-3p). The use distributive law on both sides: 476-21p=368-12p. Then rearrange to get 108=9p and the divide by 9 and you will get p=12 Hope this helps!!
Answer:
1.Non linear function
2. Linear function
3. Non linear function
4. Not a Function
Step-by-step explanation:
The equation to find the volume of a cylinder is V=
×r²×h. To find r you just divide the diameter which is 10 by 2 so r is 5. Just plug everything in and solve, V=
×5²×243.84. You should get V≈19,151.15
