Answer: Length = 11 cm
Width = 14 cm
Step-by-step explanation:
Let x = Length of the rectangle.
then, width = x+ 3
Perimeter of rectangle = 2 (length +width)
Then, Perimeter = 2 (x+x+3)
= 2 (2x+3)
Since perimeter = 50 cm
[tex]\Rightarrow\ 2(2x+3)=50[/tex]
[tex]\Rightarrow\ 2x+3=25[/tex] [Divide both sides by 2]
[tex]\Rightarrow\ 2x=22\\\\\Rightarrow\ x=11[/tex]
The dimensions are :
Length = 11 cm
Width = 11+3= 14 cm

The length of the base of an isosceles triangle is x. The length of a leg is 5x-7 The perimeter of the triangle is 41. Find x.
Step-by-step explanation:
if it is an isosceles triangle then both of his legs have the same lenght equal ti 5x-7=>P=2(5x-7)+x=41
10x-14+x=41
11x=55
x=11

#1-2: Find the value of x and the measure of all three angles
Show your work I’ll give brainliest :)
Answer:
1. x=20 ; the angles are 90 degrees31 degrees 59 degrees
2. x=16; the angles are 16 degrees 92 degrees 72 degrees
Step-by-step explanation:
1. 180=90+31+(3x-1)
180-90-31=3x-1
59=3x-1
60=3x
x=20
plug in x for the third angle
2. 180= x+5x-8+3x+44
180=9x+36
180-36=9x
144=9x
x=16
plug in x to all the angles to find the real value

You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately p = 0.18. You would like to be 99% confident that your esimate is within 1.5% of the true population proportion. How large of a sample size is required?
Answer:
435,307
Step-by-step explanation:
Given that :
p = 0.18
Zcritical = 99%
Error (E) = 1.5% = 1.5/100 = 0.0015
Sample size (n) can be obtained using the relation :
n = (Zcrit / E)^2 * (p * q)
q = 1 - p ; q = 1 - 0.18 = 0.82
Zcrit at 99% equals 2.576
n = (2.576 / 0.0015)^2 * (0.18 * 0.82)
n = (1717.3333)^2 * (0.1476)
n = 2949233.66328889 * 0.1476
n = 435306.888701440164
n = 435,307 samples

A music industry researcher wants to estimate, with a 90% confidence level, the proportion of young urban people (ages 21 to 35 years) who go to at least 3 concerts a year. Previous studies show that 21% of those people (21 to 35 year olds) interviewed go to at least 3 concerts a year. The researcher wants to be accurate within 1% of the true proportion. Find the minimum sample size necessary.
Answer:
21378
Step-by-step explanation:
The confidence level is 90%, which gives us a Z of 1.645.
Our equation is (Z^2*p*q)/e^2
(1.645^2*p*(1-.21))/ (.01^2)
E is the error proportion, .01
Q is 1-p or the proportion
P is the pop you need
With this, we can solve
and get p = 21377.5975 and rounded to 21378
Which equation can be simplified to find the inverse of y = 2x2?
StartFraction 1 Over y EndFraction = 2 x squared
y = one-half x squared
–y = 2x2
x = 2y2
x greater-than-or-equal-to 3
Given:
[tex]y=2x^2[/tex]
To find:
The equation that can be simplified to find the inverse of given equation.
Solution:
We have,
[tex]y=2x^2[/tex]
To find the inverse first we have to interchange x and y.
[tex]x=2y^2[/tex]
Now, we to solve this equation for y to find the inverse.
So, the equation [tex]x=2y^2[/tex] can be simplified to find the inverse of given equation.
Therefore, the correct option is 4.
Write 79% as a fraction or mixed number in simplest form.
Answer: 39 25/50
Step-by-step explanation:
0.78 ( 78% ) = 39/50
0.79 ( 79% ) = 39/50 + 1/2
25 is half of 50
39 25/50
79/100 is the fraction of 79%.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
A fraction represents a part of a whole.
We need to write 79% as a fraction or mixed number in simplest form.
79% we will convert to decimal number by dividing with 100.
As we know percentage is a hundredth part.
79% is the hundredth part of 79
79/100=0.79
Hence 79/100 is the fraction of 79%.

What is the equation of the line in slope-intercept form?
Answer:
The equation of the line in slope-intercept form is:
[tex]\:y=-\frac{1}{6}x\:+\:4[/tex]
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slope b is the y-interceptGiven the points on the line graph
(0, 4) (3, 3.5)Determining the slope between (0, 4) and (3, 3.5)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{3.5-4}{3-0}[/tex]
[tex]m=\frac{\frac{7}{2}-4}{3-0}[/tex]
[tex]m=-\frac{1}{6}[/tex]
Thus, the slope of the line = m = -1/6
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 4
Thus, the y-intercept b = 4
now substituting b = 4 and m = -1/6 in the slope-intercept form
[tex]y = mx + b[/tex]
[tex]\:y=-\frac{1}{6}x\:+\:4[/tex]
Therefore, the equation of the line in slope-intercept form is:
[tex]\:y=-\frac{1}{6}x\:+\:4[/tex]

abdul purchases two pairs of goggles priced the same, as well as a bottle of sun screen. The sunscreen was $12 and represents 30% of the total. How much is the purchase total?
Answer:
$40
Step-by-step explanation:
We can call the total x.
30% = 3/10, so $12 = 3/10 of the total.
This means that 12 = 3/10 of x, or 12 = 3/10 * x.
Solving,
12 = 3/10 * x
multiply both sides by 10 to get rid of the fraction
120 = 3 * x
divide both sides by 3 to get x, the total, by itself
40 = x
This means that the total is $40.
Answer:
$40Step-by-step explanation:
Let the total be x
30% of total is $120.3x = 12x = 12/0.3x = 40Total is $40
