Answer:
126 inches
Step-by-step explanation:
If your drawing is on a 1 : 40 scale, to find the scale's height, divide the ride's height by 40.
420 / 40 = 10.5
So the drawing will be 10.5 feet tall.
To convert 10.5 feet to inches, multiply it by 12.
10.5 * 12 = 126 inches

Solve for the value of x
-3x - 8 = -20
A. 4
B. 28/3
C. -28/3
D.-4|
Answer:
A. 4, X = 4
Step-by-step explanation:
-3x - 8 = -20
Move the constant to the right-hand side and change its sign
-3x = -20 + 8
Calculate the sum
-3x + -12
Divide both sides of the equation by -3
x = 4
Solution
x = 4

What is the range of the function graphed below?
Answer:
The range of the graph is:
-∞ < y < 2
Hence, option C is correct.
Step-by-step explanation:
We also know that range is the set of values of the dependent variable for which a function is defined.
In other words,
Range refers to all the possible sets of output values on the y-axis.
From the given graph, we can easily observe the vertical extent of the graph is all range values between -∞ and 2.
In other words,
The range of the function lies in the interval: ( -∞, 2)
Therefore, the range of the graph is:
-∞ < y < 2
Hence, option C is correct.

A child's ladder is made of 333 sections. Each section is \dfrac{3}{4} 4 3 start fraction, 3, divided by, 4, end fraction meters long. How long is the ladder when all 333 sections are extended to make one ladder? meters
Answer:
[tex]Ladder = 2\frac{1}{4}\ m[/tex]
Step-by-step explanation:
Given
[tex]Sections = 3[/tex]
[tex]Length = \frac{3}{4}m[/tex] per section
Required
Determine the length of the ladder
The length of the ladder is calculated by multiplying the number of sections by the length of each section.
So, we have:
[tex]Ladder = 3 * \frac{3}{4}\ m[/tex]
[tex]Ladder = \frac{9}{4}\ m[/tex]
[tex]Ladder = 2\frac{1}{4}\ m[/tex]
Hence, the length of the ladder is: [tex]2\frac{1}{4}\ m[/tex] or 2.25m

12-6x > 24
Answer:
x < -2
Step-by-step explanation:
Hey there!
The answer to your question is [tex]x < -2[/tex]
Tip: Remember to flip the inequality signs when you multiply/divide by a negative number!
[tex]12 - 6x > 24[/tex]
[tex]-6x > 12[/tex] (Subtract 12 from both sides)
[tex]x < -2[/tex] (Divide both sides by -6)

Help pls. Thank you
Answer:
[tex]\frac{1}{3}[/tex] feet
Step-by-step explanation:
The area of a rectangle is represented by the formula [tex]A = l[/tex] ×[tex]w[/tex], in which [tex]A[/tex] is the area, [tex]l[/tex] is the length, and [tex]w[/tex] is width.
Let's put in what we already know into the formula. We know that the area is [tex]\frac{5}{18}[/tex], so let's substitute that for [tex]A[/tex]. We know that the length is [tex]\frac{5}{6}[/tex], so let's substitute that for [tex]l[/tex]. This gives an equation that looks like this:
[tex]\frac{5}{18} = \frac{5}{6}[/tex] × [tex]w[/tex]
To find the width, all we need to do know is isolate [tex]w[/tex]:
[tex]w = \frac{5}{18}[/tex] × [tex]\frac{6}{5}[/tex]
[tex]w = \frac{30}{90}[/tex]
[tex]w = \frac{1}{3}[/tex]
Thus, the width is [tex]\frac{1}{3}[/tex].

If you layered 100000 cubes to make one big cube what would the dimensions of the big cube
Answer:
The dimensions of the cube would be:
Base: 46,42 units approx.Height: 46,42 units approx.Width: 46,42 units approx.Step-by-step explanation:
For this exercise, I suppose the measure of each cube is 1 unit, because there no says what is (you can replace it for ft, in, or another unit you need). How the big cube is formed by the 100.000 cubes smaller, and how a cube has its three measures equal: base, height, and width, you only need to obtain the cubic root of the total cubes (you use cubic root because you're gonna calculate a cube, for example, if you'd wanna calculate a square, you must obtain the square root of the total cubes):
[tex]\sqrt[3]{100.000} = 46,41588834[/tex]How each cube measure is 1 unit, when you calculate the volume of the cube with the value obtained, you must obtain the total of the cubes:
Volume of the cube= base * height * width Volume of the cube= 46,41588834 * 46,41588834 * 46,41588834 Volume of the cube= 100.000In this form, you know the answer 46,41588834 is the right answer. I use the number with just two decimals (46,42 approximately) but you can use the complete number if you need.
find the holes
[tex]f(x)=\frac{x+3}{(x+1)(x-2)}[/tex]
Answer:
x=-1 and x=2Step-by-step explanation:
The "holes" are the x-es where function doesn't exist.
one must not divide by 0, so given function doesn't exis if the denominator is equal 0
The product {(x+1)×(x-2)} is equal 0 if any of factors {(x+1),(x-2)} is 0, so
x + 1 = 0 or x - 2 = 0
x = - 1 or x = 2

Nolan has 4 times as many pens as Fiona, and Fiona has 6 times as many pencils as Nolan. If Nolan has a total of 23 pens and pencils, and so does Fiona, which of these is a number of pens or a number of pencils that either Nolan or Fiona has?
Nolan has 20 pens and 3 pencils, while Fiona has 5 pens and 18 pencils.
Amount determinationGiven that Nolan has 4 times as many pens as Fiona, and Fiona has 6 times as many pencils as Nolan, to determine, if Nolan has a total of 23 pens and pencils, and so does Fiona, the number of pens and pencils that either Nolan or Fiona has, the following calculation must be performed:
Pen = APencil = BN = 14A + 9B = 23 /// F = 3.5 + 19.5N = 12A + 11B = 23 /// F = 3A + 20BN = 20 A + 3 B = 23 /// F = 5 A + 18 B20 / 4 = 518 / 6 = 3Therefore, Nolan has 20 pens and 3 pencils, while Fiona has 5 pens and 18 pencils.

Use the linear combination method to solve this system of equations. What is the value of x? 3 x + 7 y = 31. Minus 3 x minus 2 y = negative 1 Negative 6 Negative 3 and two-thirds 3 and two-thirds 6
Answer:
x = -3 2/3
Step-by-step explanation:
Given the simultaneous equations;
3 x + 7 y = 31 ..... 1
-3x - 2y = -1 ..... 2
Add both expressions
7y - 2y = 31-1
5y = 30
y = 30/5
y = 6
Substitute y = 6 into equation 2
From 2;
-3x - 2y = -1
-3x - 2(6) = -1
-3x - 12 = -1
-3x = -1 + 12
-3x = 11
x = -11/3
x = -3 2/3
Hence the value of x is -3 2/3
Answer:
x = -3 2/3
