Answer:
72 cm
Step-by-step explanation:
Relative to the first bottle, there are n - 1 spaces between the first bottle and the nth bottle. Since, each bottle is placed relative to the first bottle.
Now, for the fourth bottle, that is, n = 4, there are 4 - 1 = 3 spaces between the first and fourth bottle.
Since each space is 12 cm, the distance between the first and fourth bottle is 12 cm × 3 = 36 cm.
Now, for the tenth bottle, that is, n = 10, there are 10 - 1 = 9 spaces between the first and fourth bottle.
Since each space is 12 cm, the distance between the first and fourth bottle is 12 cm × 9 = 108 cm.
So, the distance between the fourth bottle and tenth bottle is distance between tenth bottle to first bottle minus distance between fourth bottle to first bottle = 108 cm - 36 cm = 72 cm

Answer:
m = 6
Step-by-step explanation:

Un călător parcurge un drum în trei zile în prima zi merge o treime din drum și încă 15 km A doua zi parcurge două Septimi din rest iar în a treia zi ultimii 75 km Ce lungime are drumul
Answer:
Step-by-step explanation:
Fie distanța totală = x
Un călător parcurge un drum în trei zile
În prima zi merge o treime din drum și încă 15 km
= 1 / 3x + 15km
A doua zi călătorește două șapte din restul
= 2 / 7x
În a treia zi
75 km
Cât de lung este drumul
= 1 / 3x + 15 + 75 + 2/7 (2 / 3x).

Brian bought beverages for his coworkers. On Monday he bought 3 sodas and 4 iced teas for $18. On Tuesday he bought 5 sodas and 2 iced teas for $16.
Answer:
what is the question
Step-by-step explanation:
Answer:
3x+4y=18 and 5x+2y=16
x=the cost of the sodas
y=the cost of the iced teas
then you do
3x+4y=18, and 10x+4y=32 (the equation is still equivalent to 5x+2y=16, you just doubled it)
next,
10x+4y=32
-3x-4y=-18 (once the y's match, make one negative and one positive)
which leaves you with:
7x=14
which means
x=2
Plug the x value back into the equation, for this I chose to plug it back into 3x+4y=18
3(2)+4y=18
6+4y=18
4y=12
y=3
so the final answer is x=2, and y=3

What is the volume of a rectangular prism that is 1 1/2 inches by 2 1/4 inches by 4 inches? Show your reasoning
help please someone
The volume of the rectangular prism is given by the equation
A = 13 1/2 inches³
What is the Volume of a Rectangle?
The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle
Volume of Rectangle = Length x Width x Height
Volume of Rectangle = Area of Rectangle x Height
Given data ,
Let the volume of the rectangular prism be represented as A
Now , the equation will be
The length of the rectangular prism L = 1 1/2 inches
The length of the rectangular prism L = 1.5 inches
The width of the rectangular prism L = 2 1/4 inches
The width of the rectangular prism L = 2.25 inches
The height of the rectangular prism L = 4 inches
So , the volume of the rectangular prism A = Length x Width x Height
Substituting the values in the equation , we get
The volume of the rectangular prism A = 1.5 x 2.25 x 4
On simplifying the equation , we get
The volume of the rectangular prism A = 13.5 inches³
Hence , the volume of rectangular prism is 13.5 inches³

Li Juan solves the equation below by first squaring both sides of the equation.
13 - 2w = w + 6
What extraneous solution does Li Juan obtain?
will give 36 points HURRY PLEASE
Answer:
Step-by-step explanation:
(13-2w)^2 = 169 - 52w + 4w^2
(w+6)^2 = w^2 + 12w + 36
Setting them equal:
169 - 52w + 4w^2 = w^2 + 12w + 36
3w^2 - 64w + 133 = 0
Using the quadratic formula, we get
x = (64 +/- sqrt(64^2 - 4*3*133))/6
64^2-12*133 = 2500. sqrt(2500) = 50.
x = (64 +/- 50)/6.
x = 19 or 14/6 = 7/3.
Solving the original equation:
7 = 3w.
w = 7/3.
Therefore 19 is extraneous.
x = 19 is the extraneous solution Li Juan obtained.
The given equation is 13 - 2w = w + 6.
We need to solve the equation by squaring both sides of the equation.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Now, 13 - 2w = w + 6 squaring both sides of the equation.
That is, (13-2w)²= 169 - 52w + 4w²
(w+6)²= w²+ 12w + 36
Setting them equal, we get
169 - 52w + 4w² = w² + 12w + 36
⇒3w²- 64w + 133 = 0
Now, using the quadratic formula, we get
x = (64±√(64² - 4×3×133))/6
⇒x = (64±√2500)/6.
⇒x = (64±√50)/6.
⇒x = 19 or 14/6 = 7/3.
Solving the original equation, we get
7 = 3w⇒w = 7/3
Therefore, x = 19 is the extraneous solution Li Juan obtained.

Step-by-step explanation:A linear equation is given to us and we need to solve the equation by converting it into a equivalent equation that does not contain fractions . So the given equation is :-
[tex]\bf\implies \dfrac{3}{5}x + \dfrac{1}{2}=\dfrac{3}{4}[/tex]
Here the denominators of the fractions are 5 , 2 and 4. So LCM of 5 , 2 and 4 is , 20 .
So , Multiply whole equation by 20 .
[tex]\bf\implies 20 \bigg( \dfrac{3}{5}x + \dfrac{1}{2} \bigg) = 20 \times \dfrac{3}{4}\\\\\bf\implies 4\times 3x + 10 = 5\times 3 \\\\\bf\implies 12x + 10 = 15 \:\: \bigg\lgroup \blue{\bf Equivalent \ equation \ without \ fractions .}\bigg\rgroup [/tex]
Now let's solve this equation since we successfully converted it into a equivalent equation without fractions.
[tex]\bf \implies 12x + 10 = 15 \\\\\bf\implies 12x = 15-10 \\\\\bf\implies 12x = 5 \\\\\bf\implies\boxed{\red{\bf x =\dfrac{5}{12}}}[/tex]

The Guinness book of world records states that the tallest trophy is about 270 inches. If they stacked 4 of those trophies on top of each other, how high would they be?
answer plz
Hey there!
If the tallest trophy is about 270 inches, and you stack 4 of those trophies on top of each other, you'd be multiplying 270 times 4.
270×4= 1,080
So, if you stacked four 270-inch trophies on top of each other, they would be 1,080 inches high.
