Answer:
x = 20
Step-by-step explanation:
2x + 2x + 10 = 90
4x + 10 = 90
4x = 80
x = 20
Answer:
Angle AOB is made up of angle AOC and COB.
AOC + COB = AOB
Since AOB is a right angle, it is 90°.
Using the values given, AOC = [tex]2x[/tex] and COB = [tex]2x+10[/tex].
Therefore,
[tex]2x+2x+10=90[/tex]
Subtract 10 from both sides:
[tex]2x+2x+10-10=90-10[/tex]
[tex]2x+2x=80[/tex]
[tex]4x=80[/tex]
Divide both sides by 4:
[tex]\frac{4x}{4} =\frac{80}{4}[/tex]
[tex]x=20[/tex]

A rectangular box is designed to have a square base and an open top. The volume is to be 2048in.3
What is the minimum surface area that such a box can have?
Answers
Answer:
x=y=z in 3 dimensions. So, you have x2y=4=x3⟹x=y=3√4.
Step-by-step explanation:
Answer:
hi
Step-by-step explanation:
Let x = the length of the sides of the base and h = the height:
Volume = (area of base)(height)
V = x2h
2048 = x2h
2048/x2 = h
Surface Area = area of base + 4(area of vertical side)
SA = x2 + 4xh
Eliminate the h by using 2048/x2 = h:
SA = x2 + 4x(2048/x2)
SA = x2 + 8192 x-1
Take the derivative of SA wrt x, set it to zero, solve for x. Plug that value of x into the surface area equation to find the minimum surface area.

So, now it's worth[tex] = 189,000 - 28,350 \\ = 160,650[/tex]
The current worth of the property is $160,650.
What is percentage?Percentage, is a relative value indicating hundredth part of any quantity.
Formula for percent decreasePercent decrease = ( decreased value/ original value) × 100
Therefore,
Decreased value = Original value - new value
According to the question
We have
Percent decrease = 15%
Original value of the property = $ 189,000
So, 15% 0f $189,000 = [tex]\frac{15}{100}[/tex] × 189000
⇒ 15% of 189000 = $28350
Therefore, the decreased value of the property = $189000 - $28350
Decreased value of property = $160,650
Hence, the current worth of the property is $160,650.
