700<=560+0.08x
x is total sales $
the 560 is the constant weekly pay, since we're only calculating for one week.
we're adding 0.08x to account for the 8% of the total sales
solve it for x:
700-560 <= 0.08x
140 <= 0.08x
1750 <= x
or x >= 1750
meaning she needs $1750 worth of sales that week to earn atleast $700
as for C) just draw a number line with the number 1750 in the middle and the right shaded because it is 1750 or more.
Answer:
317°
Step-by-step explanation:
The total measure of the angles around the center of the circle is 360°. The sum of angles in each half (above AB or below AB) is half that, or 180°. So, the sum of angles below the line is 180°. We can use that fact to find x, then the measures of all of the angles.
(7x +1)° +90° +(9x -7)° = 180°
16x = 96 . . . . . divide by °, subtract 84
x = 6 . . . . . . . . divide by 16
Then angle AOD is ...
(7·6 +1)° = 43°
Short arc AD is 43°, so long arc ACD is 360° -43° = 317°.
arc ACD = 317°
First convert 5.2 km to feet
5.2km = 17060.4 feet
Now, multiply.
5.2 · 17060.4 = 88714.08
88714.08 feet
27.040051584 km
Answer:
steps below
Step-by-step explanation:
f(x) = 5x³ - x² - 5x + 1
Local extremes: 15x²-2x-5=0 .. gradient=0
x = (2 ± √2²-4*(15)*(-5)) / (2*15)
= (2 ± √304) / 30
= (2 ± 4√19) / 30
= (1 ± 2√19) / 15
= (1 ± 8.718) / 15
local maximum: (1 + 8.718) / 15 = 0.648
local minimum: (1 - 8.718) / 15 = - 0.515
the interval(s) where the graph is increasing: x < - 0.515 or x > 0.648
the interval(s) where the graph is decreasing: - 0.515 < x < 0.648
Answer:
5 x n
Step-by-step explanation:
The variable n can be any number, so by saying 5n, you are multiplying 5 by that variable n.
Example below
If n = 1, 5n = 5*1 = 5
If n = 2, 5n = 5*2 = 10
If n = 3, 5n = 5*3 = 15
If n = 4, 5n = 5*4 = 20
Hope this helps!
