6 has a factor of 2 and 3
4 has a factor of 2
10 has a factor of 2 and 5
The LCM = 60
Answer:
60
Step-by-step explanation:
The LCM is the lowest common multiple, this means the smallest number that 6, 4 and 10 can go into without giving a decimal number, so they give an integer.
Here's a trick, use prime factorizationPrime factorization means, write a number as the result of the multiplication of prime numbers prime numbers are numbers with only two factors, 1 and itselfSo the prime factorization of 6, 4 and 10 is6 = 2 x 3 4 = 2 x 210 = 2 x 5For each prime factor, find where it occurs most often as a factor and write it that many times in a new list. So 2 occurs most often as a factor of 4, so we use two 2s3 occurs most often as a factor of 6, so we use one 35 occurs most often as a factor of 10, so we use one 5Then multiply this new list of numbers 2 x 2 x 3 x 5 = 60 that's how you quickly get the LCMHelp plz:))) I’ll mark u brainliest

Find the units of displacement of the point (4,2) to get the image of (7,7). Chapter (transformation) (coordinates) (translation). Please answer my questions correctly. Unnecessary answers will be reported.
Answer:
The units of the displacement are (3, 5) → T (x + 3, y + 5)
Step-by-step explanation:
The rules of translation of a point
If the point (x, y) is translated h units to the right and k units up, then its image is (x + h, y + k)If the point (x, y) is translated h units to the right and k units down, then its image is (x + h, y - k)If the point (x, y) is translated h units to the left and k units up, then its image is (x - h, y + k)If the point (x, y) is translated h units to the left and k units down, then its image is (x - h, y - k)∵ Point (4, 2) is translated by (h, k)
∵ Its image is (7, 7)
∴ The x-coordinate of the point is increased from 4 to 7
∴ The point is translated to the right by h units
∵ 4 + h = 7
∴ h = 7 - 4 = 3
∴ The point is translated to the right 3 units
∵ The y-coordinate of the point is increased from 2 to 7
∴ The point is translated up by k units
∵ 2 + k = 7
∴ k = 7 - 2 = 5
∴ The point is translated up 5 units
∴ The point is translated 3 units right and 5 units up
∴ The units of the displacement are (3, 5) → T (x + 3, y + 5)
The perimeter of the rectangle below is 64 units. Find the length of side CD.
Write your answer without variables.
Answer:
CD = 18 units
Step-by-step explanation:
Given a rectangle with length x and width y, the perimeter is:
P = 2x + 2y
Here, we note that x = AB = CD, y = AD = BC, and P = 64 units. So:
2AB + 2BC = 64
We know that AB = 3z and BC = 2z + 2; plug these in:
2 * (3z) + 2 * (2z + 2) = 64
6z + 4z + 4 = 64
10z = 60
z = 6
Now that we've solved for z, we can find AB and, hence, CD because AB = CD.
AB = 3z = 3 * 6 = 18 units
Thus, CD = 18 units, as well.

A painting is made from three different colors whose ratios are as follows: 4 parts blue, 3 parts red, and 3 parts green. The blue part of the painting took 12 gallons of paint. How many gallons of paint were needed for the green part of the painting
Answer: 9 gallons
Step-by-step explanation:
Given: Ratio of colors in painting:
4 parts blue, 3 parts red, and 3 parts green.
Total parts = 4+3+3 =10
Fraction of blue = [tex]\dfrac{\text{Number of parts of blue}}{\text{total parts}}=\dfrac{4}{10}[/tex]
Since, Quantity of blue color used = 12 gallons
Let total quantity of color be x,
[tex]\dfrac{4}{10}x=12\\\\\Rightarrow\ x=\dfrac{120}{4}=30\text{ gallons}[/tex]
Total color used = 30 gallons
Color used for green part only = [tex]\dfrac{3}{10}\times30 = \text{9 gallons}[/tex]
Hence, 9 gallons of paint were needed for the green part of the painting.
A crew is shingling a roof. They complete 6.8 square feet every hour. How many square feet will they complete in 12 ½ hours of work?
Answer:
85 square feet
Step-by-step explanation:
what we know: complete 6.8 square feet every hour
what we want to know: how much square feet will be compeletein 12 1/2 hours?
12 1/2 is 12.5
6.8 square feet time 12.5 hours gives you 85 square feet :)

x2-11x+18=0 need help!
Answer:
x = 2 or
x = 9
Step-by-step explanation:
x² - 11x + 18 = 0
x² - 9x - 2x + 18 = 0
x(x - 9) - 2(x - 9) = 0
(x - 2)(x - 9) = 0
x - 2 = 0 or x - 9 = 0
x = 2 or x = 9
Thus, x = 2 or 9
-TheUnknownScientist
Answer:
x = 2, x = 9
Step-by-step explanation:
Given
x² - 11x + 18 = 0
Consider the factors of the constant term (+ 18) which sum to give the coefficient of the x- term (- 11)
The factors are - 2 and - 9 , since
- 2 × - 9 = + 18 and - 2 - 9 = - 11 , thus
(x - 2)(x - 9) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x - 9 = 0 ⇒ x = 9

3x+5=23 how would I solves this
Answer:
x = 6
Step-by-step explanation:
3x + 5 = 23
you wanna subtract 5 from both sides
3x = 18
now you wanna divide 3 from both sides to get x by itself
x = 6
and thats your answer hope that helped :)

A consumer organization estimates that over a 1-year period 18% of cars will need to be repaired once, 7% will need repairs twice, and 3% will require three or more repairs. If you own two cars, what is the probability that a) neither will need repair? b) both will need repair? c) at least one car will need repair?
Answer:
(a) 0.5184
(b) 0.0784
(c) 0.4816
Step-by-step explanation:
According to the given estimation over a 1-year period, 18% of cars will need to be repaired once, 7% will need repairs twice, and 3% will require three or more repairs.
So, the probability that a car need repair once = 18/100=0.18 ...(i)
The probability that a car needs repair twice = 7/100=0.07 ...(ii)
The probability that a car needs repair thrice or more = 3/100=0.03 ...(iii)
From equations (i), (ii), and (iii), the probability that a car needs repair = (0.18+0.07+0.03) = 0.28 ...(iv)
The probability that a car doesn't needs repair = 1-(0.18+0.07+0.03)= 1-0.28=0.72 ....(v)
Given that I own two cars, denoting the cars by A and B.
(a) The probability that neither will need repair=(Probability that car A doesn't need repair) and (Probability that car B doesn't need repair)
=0.72 x 0.72 [ from equation (v)]
=0.5184
(b) The probability that both will need repair = (Probability that car A needs repair) and (Probability that car B needs repair)
=0.28 x 0.28 [ from equation (iv)]
=0.0784
(c) The probability that at least one car will need repair= 1 - (The probability that neither will need repair)
=1-0.5184 [ by using part (a)]
=0.4816

A drive-in theater costs $20 per car, plus an additional fee of $4 per person. The cost, C, of the movie when p people are in the car can be represented by this equation: C = 20 + 4p Solve the equation for p to show How many people were in the car when the movie costed C dollars.
Answer:
[tex]P=\frac{C}{4} -5[/tex]
Step-by-step explanation:
Step one:
given
cost per drive= $20
additional fee per person= $4
let the number of persons be p
and the total cost be C
The total cost function is expressed as
[tex]C=20+4p[/tex]
Step two:
Required:
We want to make P subject of the cost function
Take 20 to the other side we have
C-20=4p
divide through by 4
P=C-20/4
simplify
P=C/4-5
[tex]P=\frac{C}{4} -5[/tex]

Answer:
4 1/2 minutes
Step-by-step explanation:
x^2-12x+__=(x-__)2
what’s the answer??
Answer: The answer is x=0
Step-by-step explanation:
Rewrite the equation as a trinomial.
x 2 + 12 x + 0
Move 0 to the right-hand side.
x 2 + 12 x = 0
Divide the coefficient of the x
-term by 2, then square the result. Add the result to both sides.
12 /2 = 6 ;6^2 = 36
x 2 + 12 x + 36 = 36
Factor the perfect square trinomial
x 2 + 12 x + 36
on the left-hand side.
( x + 6 ) 2 = 36
Take the square root of both sides and solve for x .
√ ( x + 6 )^ 2 = ± √ 36 =
x+ 6 = ± 6
x = − 6 + 6 = 0
x = − 6 − 6 = − 12
Check
If x = 0 :
( 0 ) ^2 + 12 ( 0 ) = 0
0 = 0
If x = − 12 :
( − 12 ) ^2 + 12 ( − 12 ) = 0
144 − 144 = 0
0 = 0
