48. A square's sides are equal, so we know that its area is a number multiplied by itself, or squared. To find the length of one side, you must take the square root of its area, 156.25, which is 12.5. To find the square's perimeter (how much fence we need to go around the garden) you must multiply that side by 4, to get 50. Antonine has 40 ft already, so he only needs 10 more ft, and each ft costs 4.97. Our final answer is 10*4.97, or $49.70.
49. The square root of 12 is about 3.46, plus 2 is our answer, about 5.46 cm.
Answer:
Josie: 100 + 5x
Allanah: 10 + 20x
x is to represent the unknown variable of how many times they will repeat this process.
Step-by-step explanation:
just guess and see
Sometimes it helps to put a number line in front of you. If one number is to the left of the other number on the number line, it's a lower number. If one number is to the right of the other number on the number line, it is greater.
-5 -4 -3 -2 -1 0 1 2 3 4 5
4 is a solution of x<-5
FALSE: 4 is not greater than -5
-3 is a solution of y>-2
FALSE: -3 is not greater than -2
y≤3 includes 3 as a possible solution
TRUE: 3 is less than OR EQUAL to 3
Hope this helps! :)
Answer:
5000
Step-by-step explanation:
In vertex form, the cost function is ...
C(x) = 3(x² -10x) +175 = 3(x² -10x +25) +175 -3(25)
C(x) = 3(x -5)² +100
The vertex is at x=5, so the cost function will be minimized when 5000 speed boats are produced.
