The length of the rectangle is 3ft less than twice the width,and the area of the rectangle is 27ft^2,find the diameter
Answer:
The dimensions of rectangle are:
width = w = 4.5 ftlength = l = 6 ftStep-by-step explanation:
Let 'l' be the length and 'w' be the width of the rectangle
The length 'l' of the rectangle is 3ft less than twice the width 'w'.so
[tex]l=2w-3[/tex]
Also, the area of the rectangle is 27ft^2.
[tex]A=27\:ft^2[/tex]
As the area of the rectangle has the formula:
[tex]\:A\:=\:l\times w[/tex]
so
[tex]27=\:l\times w[/tex]
so the equation becomes
[tex]27=\left(2w-3\right)\times \:w[/tex]
[tex]27=2w^2-3w[/tex]
[tex]2w^2-3w-27=0[/tex]
[tex]\left(w+3\right)\left(2w-9\right)=0[/tex]
if [tex]ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]
[tex]w+3=0\quad \mathrm{or}\quad \:2w-9=0[/tex]
[tex]w=-3,\:w=\frac{9}{2}[/tex]
as the width can not be negative, so
[tex]w=\frac{9}{2}=4.5[/tex] ft
As
[tex]l=2w-3[/tex]
[tex]l=2\left(4.5\right)-3[/tex]
[tex]l=9-3[/tex]
[tex]l=6[/tex]
So the dimensions of rectangle are:
width = w = 4.5 ftlength = l = 6 ftDiego lives 1/2 miles from school.What is 50% of 1/2

Please select the best answer from the choices provided
Answer:
c. $1,291.30
Step-by-step explanation:
Calculation what will his new annual homeowners insurance premium be
Insurance premium= [$1,106.30+ ($0.37/ $100*$50,000)]
Insurance premium=$1,106.30+$185
Insurance premium=$1,291.30
Therefore what his new annual homeowners insurance premium will be is $1,291.30

80% of teenagers have access to some social media . If you do a random survey of 400 teenagers, what is the probability that between 300 and 340 of them will patronize it.
Answer:
P(300 < p^ < 340) = 0.9876 or 98.76%
Step-by-step explanation:
We are given;
Population proportion; p = 80% = 0.8
Sample proportion; p1^ = 300/400 = 0.75 and p2^ = 340/400 = 0.85
Sample size: n = 400
z-score formula for sample proportion is;
z = (p^ - p)/(√(p(1 - p)/n)
Thus;
z1 = (0.75 - 0.8)/(√(0.8(1 - 0.8)/400)
z1 = -0.05/0.02
z1 = -2.5
z2 = (0.85 - 0.8)/(√(0.8(1 - 0.8)/400)
z2 = 0.05/0.02
z2 = 2.5
From online calculator of probability between 2 z-scores, we have;
P(-2.5 < z > 2.5) ≈ 0.9876
[solved] These Cylinders are similar. Find the volume of the smaller cylinder. Round to the nearest tenth. (the answer is 84.9 cm^3)
Answer:
84.9 cm³
Step-by-step explanation:
Height of the bigger Cylinder = 5 cm
Volume of the bigger Cylinder = 393 cm³
Height of the smaller cylinder = 3 cm
Volume of the smaller cylinder = x cm³
Since they are similar, therefore: the cube of their ratio would equal the ratio of their volume.
Thus:
[tex] (\frac{5}{3})^3 = \frac{393}{x} [/tex]
[tex] \frac{125}{27} = \frac{393}{x} [/tex]
Cross multiply
[tex] 125*x = 393*27 [/tex]
[tex] 125x = 10,611 [/tex]
Divide both sides by 125
[tex] \frac{125x}{125} = \frac{10,611}{125} [/tex]
[tex] x = 84.888 [/tex]
Volume of the smaller cylinder = 84.9 cm³ (to nearest tenth?

What is an linear equation in one variable?Linear equation is an equation containing one unknown variable with power one and constants.
The standard form of an linear equation in one variable x is :
ax + b = 0 , where a, b are constants
x= -b/ a is solution if this equation or we can solve this equation by adding or subtracting , multiplying or dividing by same number to both sides.
Let Carlos spent x hours reading last week
Given that last week the time that Carlos spent practicing piano for 3 1/2 hours = 7/2 hours = 3.5 hours
Time spent on practicing piano = 1/3 ( time spent on reading)
⇒ 3.5 = (1/3) x
Multiply both sides by 3
⇒ 3.5 ×3 =3×(1/3)x
⇒10.5 = x
Therefore, the time spent by Carlos on reading last week is 10.5 hours.
