if x is a positive integer, for how many different values of x is startroot startfraction 48 over x endfraction endroot a whole number?236
There are 3 whole number with different values of x.
What is a whole number?
All positive integers from 0 to infinity are included in the group of numbers known as whole numbers. The number line has these numbers. They are all genuine numbers as a result. Although not all real numbers are whole numbers, we may argue that all whole numbers are real numbers. As a result, the set of natural numbers plus zero may be used to define whole numbers. The category of whole numbers and the negative of natural numbers is known as integers. Thus, integers can be either positive or negative, including 0. Natural numbers, whole numbers, integers, and fractions all fall under the category of real numbers.
Whole numbers refer to all natural numbers, including '0,' in their entirety. Examples include: 0, 11,1,2,3,4 etc
As stated in the question,
Accordingly, "x" is a positive integer. In order for the value of [tex]\sqrt{\frac{48}{x} }[/tex]to be a whole number, we must determine how many alternative values there are for the variable "x".Then, in order to determine which values of "x" the given fraction is a square for, we must first locate them.
We are aware that the factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.
Now, from the above factors of 48 only (3,12 & 48) of can give us a square number.
Therefore,
If x is 3 then [tex]\sqrt{\frac{48}{3} }[/tex]=[tex]\sqrt{16}[/tex]=4If x is 12 then[tex]\sqrt{\frac{48}{12} }[/tex]=[tex]\sqrt{4}[/tex]=2If x is 48 then[tex]\sqrt{\frac{48}{48} }[/tex]=[tex]\sqrt{1}[/tex]=1Hence, There are 3 whole number with different values of x.

Which equation is true if b = 2?
2b + 24 = 30
3b - 2 = 4
B + 4 = 8
2b - 3 = 0
Answer:
2nd equation is correct.
Step-by-step explanation:
1) 2b + 24 = 30
→ 2(2) + 24 = 30
→ 4 + 24 = 30
→ 28 ≠ 30
Hence, it is false.
2) 3b - 2 = 4
→ 3(2) - 2 = 4
→ 6 - 2 = 4
→ 4 = 4
Hence, it is true.
3) B + 4 = 8
→ 2 + 4 = 8
→ 6 ≠ 8
Hence, it is false.
4) 2b - 3 = 0
→ 2(2) - 3 = 0
→ 4 - 3 = 0
→ 1 ≠ 0
Hence, it is false.

Please Please help asap!!! Thank you
Step-by-step explanation:
well, the starting equation and the target format have been given.
let's do the multiplications and compare the target with the starting information.
from there we see what is different or missing.
x² + 14x + 13 = 0
and
(x - p)² = q
x² - 2px + p² = q
x² - 2px + (p² - q) = 0
now let's compare the different parts :
x² = x²
-2px = 14x
-2p = 14
p = -7
p² - q = 13
-7² - q = 13
49 - q = 13
36 - q = 0
q = 36
so, the square (x - p)² = (x + 7)² is completed when
x² + 14x + 49 = 0
but we have only "+ 13". so we need to add 36 to get 49. but we need to do it on both sides, to keep the equation true :
x² + 14x + 13 + 36 = 36
x² + 14x + 49 = 36
(x + 7)² = 36
just as we calculated already above.
and now this can be solved by pulling the square root on both sides (a quadratic equation has always 2 solutions)
x + 7 = ±6
x1 = 6 - 7 = -1
x2 = -6 - 7 = -13

If Judy attended all sessions, yet

Therefore:

Use the formula for arc length to find the value of the unknown quantity.
s=rθ
The unknown quantity which is the radius has a length of 49752/π yards.
How to find arc length?The formula for the length of arc is;
S = rθ
where;
r is radius
θ is the central angle in radians
Now, we are given;
θ = 3π/4
S = 4146 * 9 yards
Thus, making r the subject and solving gives;
r = S/θ
r = (4146 * 9)/(3π/4)
r = 49752/π
Thus, the unknown quantity which is the radius has a length of 49752/π yards.

A large grain silo is to be constructed in the shape of a circular cylinder with a hemisphere attached to the top. The diameter of the silo is to be 30 feet, but the height is yet to be determined. Find the height h of the silo that will result in a volume of 11,475(3.14) ft cubed
The height of the silo is 56 feet.
Here, we are given that a large grain silo is to be constructed in the shape of a circular cylinder.
The diameter of the silo = 30 feet
⇒ The radius of the cylinder = 15 feet
and also the radius of the hemisphere = 15 feet
The volume of a hemisphere = 2πr^3/3
Volume = 2 × π × 15 × 15 × 15 × 1/3
Volume of cube = 2250π
Thus, the volume of cylinder = volume of the silo - volume of the hemisphere
= 11,475(3.14) - 2250π
π = 3.14
⇒ 11,475(3.14) - 2250(3.14)
3.14 (11,475 - 2250)
= 3.14 (9225)
= 9225π
Now, the volume of cylinder = πr^2h
Thus, 9225π = π(15) (15) h
9225π/ 225π = h
h = 9225/225
h = 41
Thus, the height of the cylinder = 41
The height of the silo will be the height of hemisphere + height of the cylinder = 15 + 41 = 56 feet.

Please help me find the rule of this linear function:
x-intercept: (-3.667,0)
y-intercept: (0,5.5)
Step-by-step explanation:
what do you mean by "rule" ?
the line equation (in slope-intercept form ? or any other ?) ?
or only the slope of the line ?
I assume you need the slope-intercept line equation.
this looks like
y = ax + b
"a" is the slope of the line, "b" is the y-intercept (the y value when x = 0).
"b" we know already from the specified intercept points : 5.5
the slope of a line is simply the ratio
(y coordinate change / x coordinate change)
when going from one point on the line to another.
and the axis-intercept points are points on the line too. so, we can use them.
so, we see
x changes by +3.667
(= 3 2/3 = 3×3/3 + 2/3 = (3×3 + 2)/3 = 11/3)
from -3.667 to 0.
y changes by +5.5
(= 5 1/2 = 5×2/2 + 1/2 = (5×2 + 1)/2 = 11/2)
from 0 to 5.5
the slope is therefore
5.5 / 3.667 = 11/2 / 11/3 = 11/2 × 3/11 = 3×11 / 2×11 = 3/2
and so, the line equation is
y = 3/2 x + 5.5
or
y = 3/2 x + 11/2 = 1/2 × (3x + 11)

Lord wants to run at least 1.5 miles, and her pace is shown in the picture as 3.75 miles per hour, and the question asks us to construct an inequality expressing x for the amount of hours she would have to run.
