Answer:
x ≥-1
Step-by-step explanation:
-1/2x -3 ≤ -2.5
Add 3 to each side
-1/2x -3+3 ≤ -2.5+3
-1/2x ≤ .5
Multiply each side by -2, remembering to flip the inequality
-2 * -1/2x ≥ 1/2 * -2
x ≥-1
Answer:
36
Step-by-step explanation:
Given that Kelsay opened a bag of marbles.
The bag included 4 colours of marbles of equal numbers.
The four colours are red, yellow, green and blue.
To find the no of marbles of each colour in the bag:
Total number of marbles = 144
Total colours = 4
Hence divide total number by no of colours to get the answre
No of each colour marbles = 144/4 = 36
Answer:
the height of the building is approximately 134 yards
Step-by-step explanation:
Recall that i order to use the arc-length formula:

we know the radius R, but the angle
must be given in radians. Then we convert
to radians, and then use 1700 yards as the radius in the formula.

Therefore, the arc length formula would render:

which rounded to the nearest yard becomes: 134 yards
Answer: The largest dimensions that are possible would be 50 foot by 125 foot.
Step-by-step explanation:
Since we have given that
Amount a farmer has available = $1500
Let x be the side perpendicular to the river.
Let y be the side parallel to the river.
Number of section perpendicular to the river = 3
cost of material for the side parallel to the river = $6 per foot
Cost of material for the side perpendicular to the river = $5 per foot
So, total cost becomes

Area would be

Now, put A' = 0 to get the critical points.
So, it becomes,


so, at x= 50 it will give maximum dimensions.

So, the largest dimensions that are possible would be 50 foot by 125 foot.
