Given x is an integer, when x is rounded off to 1 significant figure, the answer is 40. Write as a fraction, the ratio of the least possible value of x to the largest possible value of x.
=======================================================
Explanation:
Let's consider the number 39
We have 2 nonzero digits here, so we have 2 significant figures (sig fig for short).
The goal is to round this to one sig fig instead of two. The question is: do we keep the 3 or keep the 9 instead?
The answer is that we keep the 3 and toss the 9, but the 9 will mean we bump the 3 up to 4.
So 39 bumps up to 40 where the 0 is not a sig fig (review the many sig fig rules about how to deal with zeros). The zero is just a placeholder to help determine the magnitude of the number.
In other words, 39 is closest to 40 rather than 30. We can think of "40" as "4 tens" and even drop the unit "tens" to focus solely on that 4. It would be implied we're talking about the tens unit from then on. You hopefully agree at this point we definitely have one sig fig to focus on.
----------------
If we repeated the last set of steps for the number 38, then it also rounds to 40 when rounding to one sig fig. The same goes for 37, 36, and 35.
The values 35, 36, 37, 38, 39 all round to 40 when rounding to one sig fig.
Doing the same type of logic, but on the upper side of 40, we have the values {41,42,43,44} also rounding to 40. The value 45 won't work because it rounds to 50 instead.
Therefore, x can be any of the following integers:
35,36,37,38,39,40,41,42,43,44
and they all round to 40 when rounding to one sig fig.
--------------
The last step is to divide the smallest item of the last list mentioned over the largest item
35/44
The numerator and denominator have no factors in common other than 1. So the fraction cannot be further reduced.
Write the absolute value equations in the form (x – b |=c (where b is a number and c
can be either a number or an expression) that has the following solution set.
all numbers such that x>-1.3
The absolute value equation is:
|x + 1.3| = x + 1.3
Working with absolute value equations:
The absolute value equation that we have is:
|x - b| = c
And we want that the solution set is all the numbers larger than -1.3
Now, remember that:
| something| ≥ 0.
So the absolute value is always equal or larger than zero.
So, for example, the equation:
|x| = x
Only is true if x ≥ 0, because if x is smaller than zero, for example x = -2, we would have:
|-2| = -2
2 = -2
Which is false.
Now we want to have solutions larger than -1.3 instead of larger than zero, so we can write:
|x + 1.3| = x + 1.3
The solution of this equation is the given set.

What is the surface area of this figure? Enter your answer in the box. ft² Complex solid composed of a triangular prism and a rectangular prism. The triangular prism is centered on the top of the rectangular prism. The rectangular prism bottom face is labeled 15 ft and 5 ft. The height of the rectangular prism is labeled 8 ft. The triangular base has an altitude drawn and labeled 7 ft. The sides of the triangle are labeled 9 ft, 9 ft, and 11 ft. The height of the triangular prism is 5 ft.
Answer:
a = side length a
b = side length b = bottom triangle base b
c = side length c
h = height of prism
H = height of bottom triangle
V = volume
Atot = total surface area = all sides
Alat = lateral surface area = all rectangular sides
Atop = top surface area = top triangle
Abot = bottom surface area = bottom triangle
A triangular prism is a geometric solid shape with a triangle as its base. It's a three-sided prism where the base and top are equal triangles and the remaining 3 sides are rectangles.

What is the area?Surface area refers to the area of an open surface or the border of a multi-object, whereas the area of a plane region or plane field refers to the area of a form or planar material.
A complex solid made out of triangular and rectangular prisms. The triangular prism is centered on the rectangular prism's top.
The surface area of the shape is given as,
SA = 2(15 x 8 + 8 x 5) + 15 x 5 + 11 x 5 + 9 x 5 + 9 x 5
SA = 2(120 + 40) + 75 + 55 + 45 + 45

~[tex]\frak{Amphitrite1040:)}[/tex]Find the value of x.
Answer:
127 degrees
Step-by-step explanation:
Angles in a triangle add up to 180
180 - 44 - 83 = 53
Angles on a straight line add up to 180
180 - 53 = 127
Answer:
im not really sure but x may be 127 degrees?
Step-by-step explanation:
so i dont really remember but a triangle is 180 degrees
to find x we must find the value in the triangle. lets say y
y + 44 + 83 = 180
y + 128 = 180
y = 180 - 127
y = 53
the angle in the triangle is 53 degrees. so a line is...also 180 degrees... um so we do
x + 53 = 180
x = 127

John travels at an average speed of 90 km/h for 2 hours 30 minutes. Find the distance travelled in
km.
traveledAnswer:
225 km
Step-by-step explanation:
We know that in 1 hour he will travel 90 km, so in 2 hours, he will travel double what he did in one, so multiply 90 by 2 and we get 180. If he travelled 90 km in 1 hour, then for half that time he traveled half the distance, so 90/2 is 45. Now add 180 and 45 and we get 225 km. Hope this helps!

what are the values of the variable in the triangle below?
Answer:
2nd option
Step-by-step explanation:
using the cosine and sine ratios in the right triangle and the exact values
cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] and sin30° = [tex]\frac{1}{2}[/tex] , then
cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{12\sqrt{3} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2x = 12[tex]\sqrt{3}[/tex] × [tex]\sqrt{3}[/tex] = 36 ( divide both sides by 2 )
x = 18
and
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{y}{12\sqrt{3} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2y = 12[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
y = 6[tex]\sqrt{3}[/tex]
