Answer:
It takes 13 months for the second phone to be less expensive than the first phone.
Step-by-step explanation:
First phone: y = 100 + 55x
Second phone: y = 150 + 51x
(x = number of months, y = total cost)
Make a T-Chart.
First phone: Second phone:
<u> x | y </u> <u> x | y </u>
0 | 100 0 | 150
1 | 155 1 | 201
2 | 210 2 | 252
3 | 265 3 | 303
4 | 320 4 | 354
5 | 375 5 | 405
6 | 430 6 | 456
7 | 485 7 | 507
9 | 595 9 | 609
10 | 650 10 | 660
11 | 705 11 | 711
12 | 760 12 | 762
13 | 815 13 | 813
After 13 months, the second phone will have costed $2 less than the first phone, and the price of the second will continue to be lower than the first.
Answer:
402 cm
Step-by-step explanation:
Given :
Radius = 4 cm
The Circumference of a circle :
C = 2πr
C = 2 * π * 4 = 8π
Spool is spun 16 times :
Circumference * 16
8π * 16
8 * 3.14 * 16
= 401.92
= 402 cm
Answer: -6b - 12 + 8
Step-by-step explanation: To simplify/find an equivalent expression to -6(b + 2) + 8, we just need to get rid of the parentheses. This can be done by multplying -6 by everything insde the parentheses.
-6 × b = -6b
-6 × 2 = -12
Now, we add our answers together. Don't forget to add the 8 to the end!
-6b + -12 + 8
-6b - 12 + 8
Hope this was helpful! Let me eknow if you have any further questions. :)
2.25p + 119.75 = 500
2.25p = 380.25
p = 169
169 pastries per day equal $380.75 + $119.75 of fixed costs equal to exactly $500
15.50 i think i not exactly sure but its around there
