Answer:
340 phones
Step-by-step explanation:
Make an expression
She repairs 10 phones each day, d.
Each day she repairs 10 phones, it is 10 phones off the total number (450) she has to repair, so we can subtract 10d from 450.
450-10d
We want to find how many she has left after 11 days, so we can substitute 11 in for d
450-10(11)
Multiply
450-110
340
She will still have 340 phones left to repair
Hope this helps ;)

Answer:
Average time for West Middle was maximum.
Step-by-step explanation:
Average time for a track meet for schools =
For Eastbay Middle,
Average time per mile =
= 6 minutes per mile
For Northwest Middle,
Average time =
= 5 minutes per mile
For South Central Middle,
Average time =
= 7 minutes per mile
For West Middle,
Average time =
= 8 minutes per mile
Therefore, average time for West Middle (8 minutes per minute) was maximum.
Answer:
y = -1/2 x
Step-by-step explanation:
Option B is the correct answer.
That figure is made up of 3 shapes.
A square, a rectangle, a semicircle.
The square has a side of 6 ft.
The semicircle has a radius of 4 ft.
The rectangle's width is the diameter of the semicircle, so it is 8 ft. The length of the rectangle is 18 ft.
Square:
A = s^2 = (6 ft)^2 = 36 ft^2
Rectangle:
A = LW = 18 ft * 8 ft = 144 ft^2
Semicircle:
A = (1/2) * pi * r^2 = (1/2) * pi * (4 ft)^2 = (1/2) * pi * 16 ft^2 = 8pi ft^2
Total area:
A = 36 ft^2 + 144 ft^2 + 8pi ft^2
A = (180 + 8pi) ft^2
