If each side of a square grows 6 mm, the area of the square is multiplied by 16. How long are the sides of the original square?
Answer:
2 mm
Step-by-step explanation:
Let x be the sides of the original square,
then the area of the original square is x^2
The sides of the new square is x + 6
The area is (x + 6)^2
Then (x + 6)^2 = 16*x^2
Take square root on both sides and get
x + 6 = 4x,
3x = 6
so x = 2 mm

PS = 45
Step-by-step explanation:
Perimeter of P Q R S is :
( 4x + 1 ) + ( 2x - 3 ) + ( 2x - 3 ) + 4 + ( 4x + 1 )
4x + 1 + 2x - 3 + 2x - 3 + 4 + 4x + 1
And in the question , given that the perimeter of this figure is 288.
Now let us find the value of x.
4x + 1 + 2x - 3 + 2x - 3 + 4 + 4x + 1 = 288
4x + 2x + 2x + 4x + 1 - 3 - 3 + 4 + 1 = 288
12x + 0 = 288
12x = 288
Divide both sides by 12
x = 24
And now let us find the value of PS
PS = 2x - 3
PS = 2× 24 - 3
PS = 48 - 3
PS = 45
Hope this helps you :-)

Flaws in a certain type of drapery material appear on the average of one in 150 square feet. If we assume a Poisson distribution, find the probability of at least one flaw appearing in 300 square feet.
Using the Poisson distribution, it is found that there is a 0.8647 = 86.47% probability of at least one flaw appearing in 300 square feet.
What is the Poisson distribution?In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
The parameters are:
x is the number of successese = 2.71828 is the Euler number[tex]\mu[/tex] is the mean in the given interval.Flaws in a certain type of drapery material appear on the average of one in 150 square feet, hence, considering 300 square feet, the mean is of:
[tex]\mu = \frac{300}{150} \times 1 = 2[/tex]
The probability of at least one flaw appearing in 300 square feet is given by:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-2}2^{0}}{(0)!} = 0.1353[/tex]
Then:
[tex]P(X \geq 1) = 1 - 0.1353 = 0.8647[/tex]
0.8647 = 86.47% probability of at least one flaw appearing in 300 square feet.

Write the equations of the lines described.
The line has a slope of 1/5 and y-intercept of (0, -4)
Answer:
y=1/5x-4
Step-by-step explanation:
Hi there!
We want to write the equation of the line, and we're given that the line has a slope of 1/5, and the y intercept of the line is (0, -4)
There are multiple ways to write the equation of the line, the most popular being slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
We are already given the slope (1/5), so we can plug it in as m in the equation.
y=1/5x+b
Now for b, we are also given the y intercept; the value of b is the value of y at the point of the y intercept
In this case, b would equal -4
So substitute -4 as b into the equation:
y=1/5x-4
This is the equation of the line.

find the error!
Answer:
Step 1
Step-by-step explanation:
they were supposed to multiply 2x by 4 and -1 by 4 but they only multiplied 2x by 4.
Answer:
B. Incorrect with error in STEP 1
Step-by-step explanation:
3x - x + 4 = 4(2x - 1)
Step 1: Simplify
2x + 4 = 8x - 4
Step 2: Subtract 8x from both sides.
2x+4−8x=8x−4−8x
−6x+4=−4
Step 3: Subtract 4 from both sides.
−6x+4−4=−4−4
−6x=−8
Step 4: Divide both sides by -6.
-6x/-6 = -8/-6
x = 4/3
so, the other answer is wrong because she did not multiply the numbers in the parenthesis correctly

1/3(z+1/5)=-2/5 what’s z?
Answer:
(exact form) z= -7/5
or
(decimal form) z= -1.4
or
(mixed number form) z= -12/5
Step-by-step explanation:
Answer:
The value of z is -7/5
Step-by-step explanation:
1/3 (z + 1/5) = -2/5
z/3 + 1/5 × 3 = -2/5
z/3 + 1/15 = -2/5
15z + 3/45 = -2/5
15z + 3 = -2(45) ÷ 5
15z + 3 = -2(9)
15z + 3 = -18
15z = -18 – 3
15z = -21
z = -21/15
z = -7/5
Thus, The value of z is -7/5
