the given expression can be solved as follows ~
[tex] \frac{x}{13} - 1 = \frac{5x}{2} + \frac{1}{2} \\ [/tex]
taking LCM both the sides ,

In a group of 60 workers, the average salary is $80 a day per worker. if some of the workers earn $75 a day and all the rest earn $100 a day how many workers earn $75 a day?
The total number of workers that earn $75 per day is 48
What is average salary?The average salary is calculated based on reported salaries of respondents. The average salary definition is to add the salaries in the sample together, then divide by the number of respondents.
Given that:
In a group of 60 workers, the average salary is $80 a day per worker.
If some of the workers earn $75 a day and all the rest earn $100 a day.
Let 'x' be the total number of workers that earn $75 per day.
So, the total number of workers that earn $100 per day is (60 - x).
As the average salary of 60 workers is $80.
Then,
[tex]\frac{75x + 100(60-x)}{60} =80[/tex]
or, 75 x + 6000- 100x = 80*68
or, -25x= -1200
x= 48
So, the total number of workers earn $75 per day is 48.

Volume = l·w·h
After cutouts:
l = 14 - 2x
w = 6 - 2x
h = x
V = (14 - 2x)(6 - 2x)(x) in3
V = 4x3 - 40x2 + 84x in3
To maximize the volume, take the derivative of V with respect to x, set it equal to zero, and solve for x:
dV/dx = 0 = 12x2 - 80x + 24
x2 - (20/3)x + 7 = 0
x = (10 ± √37)/3 in
Since (6 - 2x) yields a negative number for x = (10 + √37)/3 we use only x = (10 - √37)/3
Thus, the dimensions are:
l = 14 - 2x = 11.39 in
w = 6 - 2x = 3.39 in
h = x = 1.31 in

[tex]\frac{BC}{DE} = \frac{AB}{BD}[/tex]8/16 = x/10x/10 = 1/2x = 10/2x = 5Answer:
x = 10.
Step-by-step explanation:
Triangles ABC and ADE are similar so their corresponding sides are in the same ratio.
So we have:
8/16 = x / (x + 10)
16x = 8(x + 10)
16x - 8x = 80
8x = 80
x = 10
The base of a solid is bounded by the curve y = sqrt (x+1) the x-axis and the line x = 1. the cross sections, taken perpendicular to the x-axis, are squares. find the volume of the solid.
a. 1
b. 2
c. 2.333
d. none of these
(will vote brainlest, like and rate)
See attached for a sketch of some of the cross sections.
Each cross section has area equal to the square of the side length, which in turn is the vertical distance between the curve y = √(x + 1) and the x-axis (i.e. the distance between them that is parallel to the y-axis). This distance will be √(x + 1).
If the thickness of each cross section is ∆x, then the volume of each cross section is
∆V = (√(x + 1))² ∆x = (x + 1) ∆x
As we let ∆x approach 0 and take infinitely many such cross sections, the total volume of the solid is given by the definite integral,

Which expression represents the volume, in cubic units, of empty space in the cube? four-thirdsπ(4.53) – (4.5)3 (9)3 – four-thirdsπ(4.52) four-thirdsπ(4.53) – (9)3 (9)3 – four-thirdsπ(4.53)
The expression that represents the volume of the empty space is 9³ - 4 / 3 π(4.5)³ cubic units.
How to find the expression for volumes?
The volume of the empty space can be represented as follows
volume of the empty space = volume of cube - volume of sphere
Therefore,
volume of sphere = 4 / 3 πr³
where
r = radiusVolume of cube = L³
where
L = side lengthTherefore,
volume of cube = 9³
