What is the perimeter of this tile? inz 10 in. 8 in. 6 in.​

Answer:

3(4x - 2.5) = 5(0.4x + 10) + 33

3•(4•x - 2.5) = 5•(0.4•x + 10) + 33

10x = 90.5

x = 181/ 20

= 9.05

Step-by-step explanation:

9514 1404 393

Answer:

  x = 9.05

Step-by-step explanation:

Start by eliminating parentheses.

  12x -7.5 = 2.0x +50 +33

  10x = 90.5 . . . . . . . . . . . . . add 7.5-2x

Answer:

If a resident who is 30-49 years old is chosen at random, the probability that they have completed a bachelor's degree and no more is 29.13%.

Step-by-step explanation:

Taking into account the educational table provided, if a resident who is 30-49 years old is chosen at random, to determine what is the probability that they have completed a bachelor's degree and no more the following calculation must be performed:

30-39 Bachelor's degree = 1576

40-49 Bachelor's degree = 443

30-39 Total = 4062

40-49 Total = 2869

4062 + 2869 = 100

1576 + 443 = X

6931 = 100

2019 = X

2019 x 100/6931 = X

201900/6931 = X

29,129 = X

Therefore, if a resident who is 30-49 years old is chosen at random, the probability that they have completed a bachelor's degree and no more is 29.13%.

Answer:

Probability : [tex]\frac{1008}{3407}[/tex]​

≈0.296

Answer:

[tex]3x - 8 = 2x + 12 \\ x = 12 + 8 = 20 \\ 180 - 2x - 12 = y \\ y = 180 - 40 - 12 = 128[/tex]

Answer:

450 x 1.08 ^ X = N

Step-by-step explanation:

Since in 2002, there were 450 households in the city of Klean that recycled, and each year since 2002, the number of households that recycle has grown by 8%, to write a function to represent the number of households in Klean that recycle X years since 2002 the following mathematical reasoning should be raised:

450 (initial number) x 1.08 (8% is added to the initial number) ^ X (years) = Number of households that recycle

450 x 1.08 ^ X = N

Thus, for example, if said number were calculated in 2007, that is, 5 years after 2002, the equation would apply as follows:

450 x 1.08 ^ 5 = N

450 x 1.4693 = N

661.20 = N

Answer:

  8√2 units

Step-by-step explanation:

The distance formula is useful.

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((10 -2)² +(5 -13)²) = √(64 +64)

  d = 8√2

The length of AB is 8√2 units.

Step-by-step explanation:

Answer:

H0 : σ²= 7.2²

H1 : σ² < 7.2

We can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.

Step-by-step explanation:

H0 : σ²= 7.2²

H1 : σ² < 7.2²

The test statistic :

X² = [(n - 1)*s² ÷ σ²]

s² = 3.5

n = sample size = 25. ; s²

X² = [(25 -1)*3.5² ÷ 7.2²

X² = (24 * 3.5^2) / 7.2^2

X² = 5.67

Pvalue from Chisquare statistic :

P(X² < 5.67) = 0.000042

Pvalue < α ; we reject the Null.

Hence, we can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.

Base of parallelogram = 20 meter

Step-by-step explanation:

Given:

Area of parallelogram = 100 square meters

Height of parallelogram = 5 meters

Find:

Base of parallelogram

Computation:

Area of parallelogram = [Base of parallelogram][Height of parallelogram]

By putting value in the formula;

100 =  [Base of parallelogram][5]

Base of parallelogram = 100 / 5

Base of parallelogram = 20 meter

Step-by-step explanation:

Big triangle = 1/2 * 3.5 * 9 = 15.75

Tiny triangle = .5 * 2 * 2 = 2

Medium triangle = .5 * 2 * 5 = 5

square = 2 * 2

Answer:

30.96 ft²

Step-by-step explanation:

area of square = 12 x 12 = 144 ft²

area of circle = (3.14)(6²) = 113.04 ft²

144 - 113.04 = 30.96 ft²

Answer:

G. the houston building is 27 yd taller than the dallas building

Step-by-step explanation:

1,002 ft

= 334 yards (Houston)

307 yards (Dallas)

F. Incorrect because the Houston building is taller.

G. 334 - 307 = 27 (This is true)

695 ft is not equal to 27 therefore, H and J are not true.

Step-by-step explanation:

The endpoints of the diameter are A(-4,1) and B(4,2) . For finding the equation of circle we need to find the centre and the radius.

Coordinates of centre can be find out by the midpoint formula.

[tex] \implies Center = \bigg(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\bigg)\\\\\implies Centre = \bigg(\dfrac{-4+4}{2},\dfrac{1+2}{2}\bigg)\\\\\implies \boxed{\boxed{Centre = (0 , 1.5)}}[/tex]

Now the measure of radius can be obtained by half the distance between them.

[tex]\implies D = \sqrt{ (x_2-x_1)^2+(y_2-y_1)^2}\\\\\implies D =\sqrt{ (4+4)^2+(2-1)^2}\\\\\implies D = \sqrt{ 64 + 1 }\\\\\implies D =\sqrt{65} \\\\\implies \boxed{\boxed{ Radius = \dfrac{\sqrt{65}}{2} }}[/tex]

We know the general equation of circle as ,

[tex]\implies (x-h)^2+(y-k)^2= r^2[/tex]

[tex]\implies (x-0)^2+ (y-1.5)^2 = \bigg(\dfrac{\sqrt{65}}{2} \bigg)^2\\\\\implies x^2 + (y-1.5)^2=\dfrac{65}{4} \\\\\implies\boxed{\boxed{ 4x^2+4(y-1.5)^2 = 65 }}[/tex]

Answer:

(2.5 , 3.5)

Step-by-step explanation:

We can use the midpoint formula . Here the points are , (2,2) and (3,5) .

• Using Midpoint Formula :-

⇒ M = { (x1 + x2)/2 , (y1 + y2)/2 }

⇒ M = ( 2+3/2 , 5+2/2 )

⇒ M = ( 5/2 , 7/2 )

⇒ M = ( 2.5 , 3.5 )

Answer:18

Step-by-step explanation:

18 inches represent 225 miles.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Suppose we have two ratio p : q and r : s.

If both these ratios are proportional, then we can write it as p: q : : r : s.

This is same as p : q = r : s or p/q = r/s

Given that,

2 inches on a map represents 25 miles.

We have to calculate the value of inches that correspond to 225 miles.

Let x be the unknown value of inches that correspond to 225 miles.

Using proportional concept,

2 : 25 = x : 225

This can also be written as,

2 / 25 = x / 225

Cross multiplying,

2 × 225 = 25 x

x = (2 × 225) / 25

x = 18

Hence the value of the unknown inch is 18 inches.

Answer:

B

Step-by-step explanation:

so your starting value (10) is not going to have the x by it. instead he is feeding his dog so it will be subtracted from.

x is the number of days he can feed his dog. this will be mulitplied with something.

0.5 is how much he feeds his dog each day. this will be times the number of days or x.

so it makes your answer [tex]y=10-0.5x[/tex]

Answer:

x=50

y=40

p=130

Step-by-step explanation:

A whole circle is 360 degrees, so 270+40+x = 360. x=50.

Y is the same angle as the 40 degrees above it.

P is the same as y+90, so it's 40+90 = 130.
