In both cases, we have cooling. We can add together the 2 functions describing this cooling: z(x) = 0.5x - 9 - [-x-2] = 0.5x - 9 + x + 2, or
z(x) = 1.5x - 7
Provided that this is correct, all we have to do now is to subst. 5 for x:
z(5) = 1.5(5) - 7 = 7.5 - 7 = 0.5 (answer)
Answer:
Multiply the number of attempts by the percentage:
75 attempts x 0.65 = 48.75
Round up to 49 shots.
2A. Answer is 42.7. C squared minus B squared equals A squared. C^2 - B^2 = A^2. 48^2 - 22^2 = 42.66^2.
Answer:
Step-by-step explanation:
3C + 8T = 58 ----- (eq1)
5C + 2T = 23 ------(eq2)
Multiply equation (1) by 5 and equation (2) by 3
15C + 40T = 290 -----(eq3)
15C + 6T = 69 ----------(eq4)
Subtract equation (4) from (3)
34T = 221
T = 221/34
T = $6.5
Therefore 1 Table will cost $6 and 5 cents
Solve for (C) in equation (1)
3C + 8T = 58
3C + 8(6.5) = 58
3C + 52 = 58
3C = 58-52
3C = 6
C = 6/3
C = $2
1 Chair will cost $2
