The LCM of 4 and 7 is 28
Step-by-step explanation:
LCM is the lowest common multiple of two or more numbers.
To find it do that:
List the multiples of each numberFind the first common multiple of them, it will be the LCMLet us find the lowest common multiple of 4 and 7
→ List the multiples of 4
∵ The multiples of 4 are, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, .......
→ List the multiples of 7
∵ The multiples of 7 are, 7, 14, 21, 28, 35, 42, 49, .........
→ Find the first common multiple of 4 and 7
∵ 28 is the first common multiple of 4 and 7
∴ The lowest common multiple of 4 and 7 is 28
∴ The LCM of 4 and 7 is 28

A rectangle is 3 cm longer than it is wide. The diagonal is 15 cm. Find the dimensions of the rectangle?
Answers
Answer:
The length is 12 cm, and the width is 9 cm.
Step-by-step explanation:
The length and width of a rectangle as legs form a right triangle with the diagonal of the triangle as the hypotenuse.
We can use the Pythagorean theorem to write an equation.
Let the width = w = leg a
The length = w + 3 = leg b
The diagonal = the hypotenuse = 12 = c
a^2 + b^2 = c^2
w^2 + (w + 3)^2 = 15^2
w^2 + w^2 + 6w + 9 = 225
2w^2 + 6w - 216 = 0
w^2 + 3w - 108 = 0
(w + 12)(w - 9) = 0
w + 12 = 0 or w - 9 = 0
w = -12 or w = 9
Since a width cannot be a negative number, we discard the solution w = -12.
width = w = 9
length = w + 3 = 9 + 3 = 12
Answer: The length is 12 cm, and the width is 9 cm.
For nitrogen to be a liquid, its temperature must be within 12.78 °F of –333.22 °F. Which equation can be used to find the maximum and minimum temperatures at which nitrogen is a liquid, x?
The equation that can be used to find the maximum and minimum temperatures is
Answers
Answer:
For nitrogen to be a liquid, its temperature must be within 12.78 °F of -333.22 °F. The equation |x + 333.22 | = 12.78 can be used to find x, which represents the maximum and minimum temperatures at which nitrogen is a liquid.

A photography studio charges $50 for a sitting fee and 6 prints. Luigi increased his order to 11 prints and paid $65. Write an equation in point-slope form.
HELP ME PLEASEEEE!!!
Answers
Answer: Sitting fee - 32$
Step-by-step explanation:
This is a system of equations(let x represent the sitting fee)
x+6y=50
x+11y=65
You want to isolate the x variable - x+6y-6y=50-6y ; x = 50-6y
Input this into the 2nd equation: 50-6y+11y=65 ; 50+5y=65
Subtract 50 from both sides. 5y=15 (Divided 5y on both sides) ; y=3
Now that y = 3 input this into any equation I choose the 1st one.
x+6(3) = 50 ; x + 18 = 50 (Subtract 18 on both sides to get x)
x = 32
Prove: 32 + 6(3) = 50 ; 32+18 = 50 ; 50 = 50 True

Answer:
C.) y = 5/4x - 4
Step-by-step explanation:
Points: (0,-4) and (4,1)
m = y2 - y1/x2 - x1
m = 1 - (-4)/4 - 0
m = 1 + 4/4
m = 5/4
Point: (4,1) (you may choose any points, but I will choose these since they are the easiest to work with)
y - y1 = m(x - x1)
y - 1 = 5/4(x - 4)
y - 1 = 5/4x - 5
y = 5/4x - 5 + 1
y = 5/4x - 4

Step-by-step explanation:
The order of operations is PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction From Left to Right.
First is Exponents.
5² = 5×5 = 25
From left to right, division comes first.
36 ÷ 6 = 6
Then multiplication.
6 × 3 = 18
Lastly, addition.

Calculate the average time it took the car to travel 0.25 and 0.50 meters with two washers attached to the pulley. Record the averages, to two decimal places, in Table C of your Student Guide.
What is the average time it took the car to travel 0.25 meters?
seconds
What is the average time it took the car to travel 0.50 meters?
seconds
Answers
Answer:
1.92 second at 0.25 meters.
2.61 second at 0.50 meters.
Step-by-step explanation:
the average 2 washers on time travel of:
0.25 m : 1.94 / 1.95 / 1.87 = 1.92 second
0.50 m: 2.69 / 2.72 / 2.42 = 2.61 second
In this exercise we have to calculate the time that a car makes in a certain distance, in this way we find that:
A) In 0.25 meters in 1.92 second.
B) In 0.50 meters in 2.61 seconds.
We know that some information is given in the statement as:
In 0.25 meters the car speeds are: 1.94/ 1.95/ 1.87In 0.50 meters the car speeds are: 2.69 / 2.72 / 2.42Knowing that the formula for calculating time is given by:
[tex]Time= Distance/Speed[/tex]
So we have:
A) [tex](1.94 +1.95 + 1.87)/3= 5.76\\0.25/5.76=1.92 s[/tex]
B) [tex]2.69+ 2.72 + 2.42= 7,83\\0.50/7,83=2,61[/tex]

[tex]x=3\sqrt{2}\\[/tex]
Step-by-step explanation:
Since the smaller triangles have a side of the same length, they share one side, and the included angle is 90°, the triangles are congruent.
This means the length of the side to the left is also x as shown in the image below.
The bigger triangle is also right and has side lengths of x, x, and 6 (the hypotenuse), thus:
[tex]x^2+x^2=6^2[/tex]
Operating:
[tex]2x^2=36[/tex]
[tex]x^2=18[/tex]
Since 18=9*2
[tex]x=\sqrt{9*2}[/tex]
[tex]\mathbf{x=3\sqrt{2}}[/tex]

The answer is the first option that states that you can write this expression as [tex]7(\frac{x}{8}) + \frac{3}{4} = -6[/tex]
Step-by-step explanation:
In order to solve this question we will need to know how to factor fractions. In our case we can do the following.
[tex]\frac{7}{8}x = \frac{7x}{8} = 7(\frac{x}{8})[/tex]
So now we since [tex]\frac{7}{8} x= 7(\frac{x}{8} )[/tex] ⇒
⇒ [tex]\frac{7}{8}x + \frac{3}{4} = -6[/tex]
[tex]7(\frac{x}{8}) + \frac{3}{4} = -6[/tex]
