Volume of a rectangular prism is V = L x W x H
The length for the small prism is 6
The width for the small prism is 4
The height for the small prism is 3
So 6 x 4 x 3 = 72
The length for the large prism is 16
The width for the large prism is 9
The height for the large prism is 2
So 16 x 9 x 2 = 288
Now you add the two volumes together: 288 + 72 = 360 ft cubed.
Four more than 5 times the number x is less than 50
Answer:
4+5x<50
Step-by-step explanation:
5n < 50 <--- subtracts 4 from both sides
n < 10 <--- divides both sides by 5
Check: testing n=0, we have 4 + 5(0) = 4 + 0 = 4 < 54, so yes it works
testing n=10, 4 + 5(10) = 4 + 50 = 54.
testing n=11, 4 + 5(11) = 4 + 55 = 59 <--- fails as expected.
X < 10, proven, verified, correct
The inequality 'Four more than 5 times the number x is less than 50' translates to '5x + 4 < 50'. By solving, we find the solution is 'x < 9.2', indicating that x must be less than 9.2.
Explanation:The question "Four more than 5 times the number x is less than 50" can be translated into a mathematical inequality. The 'four more than' suggests addition, and '5 times the number x' indicates multiplication.
Therefore, we have the inequality 5x + 4 < 50. To find the range of values for x, we need to solve the inequality for x.
Step 1: Subtract 4 from both sides to isolate the term with x on one side of the inequality. 5x < 46.
Step 2: Divide both sides by 5 to solve for x. x < 9.2.
So, the solution to the inequality is that x must be less than 9.2. This inequality does not require the quadratic formula as suggested in some parts of the provided information.
The assumption that 'The value of x is not less than 5% of 0.50' is also not relevant to solving this particular inequality.

Find the inverse of y=7x-10. Is the inverse a function?
Answer: [tex]f^{-1}[/tex] (x) = [tex]\frac{x+10}{7}[/tex]
Step-by-step explanation:
To find the inverse , all we need do is to make x the subject of the formula.
y = 7x - 10
Add 10 to both sides
y + 10 = 7x
divide both sides by 7
Therefore:
x = y + 10 / 7 , that is
[tex]f^{-1}[/tex] (x) = [tex]\frac{x+10}{7}[/tex]
Answer:
Step-by-step explanation:
y=7x-10 calculate x : 7x-10 =y
7x = y+10
x = 1/7 y +10/7

These two boxes have the same volume.
Box A
Height: 2 in., Width: 3 in., Length: 6 in.
Box B
Height:3in., Width:4in., Length:?
What is the length of Box B?
A.2in
B.3in
C.4in
D.9in
Answer:
Option B.) 3 inches
Step-by-step explanation:
Let us first express some principles that we can use to solve our problem. Generally, the Volume of a Box is given by:
[tex]V=h*w*l[/tex]
where
[tex]V[/tex] : is the volume
[tex]h[/tex] : is the height
[tex]w[/tex] : is the width
[tex]l[/tex] : is the length
Now we know that:
Volume of Box A ( [tex]V_{A}[/tex] ) is Equal to Volume of Box B ( [tex]V_{B}[/tex] ) so we have:
[tex]V_{A}=(2in)(3in)(6in)\\V_{A}=36 in[/tex]
So now we can find the Length ( [tex]l_{B}[/tex] ) of Box B easily, as we now the volume along with the height and the width, as follow:
[tex]V_{A}=V_{B}=36in\\\\36in = (3in)(4in)l_{B}\\\\36in=(12in)l_{B}\\\\l_{B}=\frac{36in}{12in}\\ \\l_{B}=3in[/tex]
So the Length of Box B is 3 inches, thus Option B. is correct.

1. In a factory, all employees work a basic week of 38 hours. Any overtime worked during week-days is paid for at time and a half. Overtime worked on Saturday is paid for at double-time,whilst on Sunday it is paid for triple-time. If the basic rate is $8.96 per hour, determine the gross wage of a man who worked 15 hours overtime from Monday to Friday, 3 hours overtime on Saturday and 2 hours overtime on Sunday.
2. In an urea manufacturing plant, all employees work a basic week of 40 hours. Any overtime worked during weekdays is paid for at time -and-a-quarter. Overtime worked on Saturday is paid for time-and-a-half, whilst on Sunday it is paid for at double-time. If the basic rate is $14.60 per hour and a man worked 15 hours overtime during weekdays, 6 hours overtime on Saturday and 5 hours overtime on Sunday. Calculate:
(a) His basic wage
(b) His overtime wage
(c) His gross wage for the week.
3. At a chemical factory, the basic week is 40 hours. During a particular week Mr. James earned a gross wage of $518.00, but $148.00 was for overtime.
(a) Calculate Mr. James basic rate of payment.
(b) If overtime was paid for at double-time,calculate how many hours Mr. James worked overtime.
Answer:
Step-by-step explanation:
1. reg pay: 8.96,week days: 1.5 overtime pay, sat: double pay, sun: triple pay
38 hrs regular pay : 38 * 8.96 = 340.48
15 hrs overtime during week : 15 * 1.5(8.96) = 15 * 13.44 = 201.60
3 hrs overtime on saturday: 3 * 2(8.96) = 3 * 17.92 = 53.76
2 hrs overtime on sunday: 2 * 3(8.96) = 2 * 26.88 = 53.76
Gross wage = (340.48 + 201.60 + 2(53.76) = 649.60 <====
===============================
2. reg pay : 14.60, weekday pay: 1.25,sat pay: 1.5 , sun pay: double
(a) basic wage = 40(14.60) = 584 <==
(b) overtime wage : 15 * 1.25(14.60) + 6 * 1.5(14.60) + 5 * 2(14.60) = (15 * 18.25) + (6 * 21.9) + (5 * 29.2) = 273.75 + 131.40 + 146 = 551.15 <==
(c) gross wage : 584 + 551.15 = 1135.15 <==
================================
3. basic work wk: 40 hrs...earned 518...overtime 148
(a) basic pay rate : (518 - 148) / 40 = 370/40 = 9.25 per hr <==
(b) if overtime is paid for at double time.....so overtime pay is (2 * 9.25) = 18.50 per hr....and he got paid 148....148/18.5 = 8 hrs <==
The gross wage of the man who worked overtime from Monday to Friday, on Saturday, and on Sunday is $582.40.
Explanation:In order to determine the gross wage of the man, we need to calculate the wages for each type of overtime worked. Let's start with the basic wage calculation for each scenario:
Question 1:
The man worked 15 hours overtime on week-days, so he will receive 15 x 8.96 = $134.40 for week-day overtime.
He also worked 3 hours overtime on Saturday, so he will receive 3 x (2 x 8.96) = $53.76 for Saturday overtime.
Lastly, he worked 2 hours overtime on Sunday, so he will receive 2 x (3 x 8.96) = $53.76 for Sunday overtime.
Now let's calculate the gross wage by adding the basic wage and the overtime wages together:
Gross Wage = Basic Wage + Week-day Overtime Wage + Saturday Overtime Wage + Sunday Overtime Wage
= (38 x 8.96) + 134.40 + 53.76 + 53.76
= $340.48 + $134.40 + $53.76 + $53.76
= $582.40

You're locked out of your
house and the only open
window is on the second
floor, 20 feet above the
ground. You need to borrow
a ladder from one of your
neighbors. There's a bush
along the edge of the house,
so you'll have to place Lie
ladder 15 feet from the
house. What length of
ladder do you need to reach
the window?
Answer:
25 feet
Step-by-step explanation:
In this problem, you would need to use the pythagorean theorem, a^2 + b^2 = c^2.
It doesn't matter which you decide to be a and which you decide to be b, but the diagonal line, or hypotenuse, must be c. In this case, that is the ladder.
Now you plug numbers into the equation. 20^2 + 15^2 = c^2.
Simplify the left side of the equation. 400 + 225 = c^2, 625 = c^2.
Now, since c is still squared, take the square root of both sides. c = 25.
Another way to solve this is using the special triangles. One of the easiest to remember is the 3-4-5 triangle. That is what this triangle is, once you factor out a 5 from all of the numbers (15/5=3, 20/5=4, 25/5=5). Them you just multiply whatever missing number you are looking for by the factor you took out (5 × 5 = 25).

Consider the graph and equation, y = 3x, that represent Alonso’s walking speed. What relationship is represented by this equation and graph? What would the points (3, 9) and (5, 15) represent?
Answer:
The equation y = 3x represents a proportional relationship, where y represents distance in miles, and x represents time in hours. The point (3, 9) represents that Alonso walks 9 miles in 3 hours. The point (5, 15) represents that Alonso walks 15 miles in 5 hours.
The graph of line y = 3x represents how much distance is covered in how much time.
Here x is the time and y represents distance traveled. So, for points (3, 9) and (5, 15), it represents that Alonso covered 9 units of distance in 3 units of time and 15 units of distance in 5 units of time.
What is the equation of line?The general equation of line is,
y = mx + c
where m is the slope and c is the intercept.
Now the given equation is,
y = 3x
This represents Alonso's walking speed.
So it is explained that y distance is covered in x time.
Hence for points (3,9),
x = 3
y = 9
So,
Alonso covered 9 units of distance in 3 units of time.
For point (5,15)
x = 5
y = 15
So,
Alonso covered 15 units of distance in 5 units of time.
Thus,for points (3, 9) and (5, 15), it represents that Alonso covered 9 units of distance in 3 units of time and 15 units of distance in 5 units of time.

The difference between two numbers is 9. The first number plus twice the other number is 27. Find the two numbers.
The two numbers are 15 and 6
Solution:
Let the two number be "a" and "b"
Let the first number be "a" and second number be "b"
Given that,
The difference between two numbers is 9
a - b = 9 -------- eqn 1
The first number plus twice the other number is 27
First number + twice the second number = 27
a + 2b = 27 ---------- eqn 2
Let us solve eqn 1 and eqn 2
From eqn 1,
a = 9 + b ------ eqn 3
Substitute eqn 3 in eqn 2
9 + b + 2b = 27
3b = 27 - 9
3b = 18
Divide both sides of equation by 3
b = 6Substitute b = 6 in eqn 3
a = 9 + 6
a = 15Thus the two numbers are 15 and 6

Step-by-step explanation:
Given equations are:
[tex]4x-9y = 20\ \ \ \ Eqn1\\2x-6x = 16\ \ \ \ Eqn2[/tex]
In linear combination method, we have to make coefficients of any one variable opposites by multiplying with an integer
