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.

Answer:

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

Answer:

(-4, -3)

Step-by-step explanation:

I think this is the answer.

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.

Answer:

3x + 12

Step-by-step explanation:

Use the distributive property.

3(x + 4) = 3 * x + 3 * 4 = 3x + 12

Answer: 3x + 12

Answer:

3x+12

Step-by-step explanation:

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]

SA = 1200

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.

Answer: 12, B

Answer:

63

Step-by-step explanation:

50 % of 210 = 105

one fifth of total = 42

black masks = (105+42=) - 210 = 63 ans.

Answer:

25.75 sq units

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

15.75 + 4 + 5 + 2

Answer:

The tallest building in the city is the Bank of America Plaza, which rises 921 feet (281 m) in Downtown Dallas and was completed in 1985.

Step-by-step explanation:

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:

Let the number be x. Then x + 10 = 20.

This is all you need to write out. But, for practice, find the solution as well.

Answer:

let the number be x

now,

x+10 =20

or,x=20-10

= x=10

Step-by-step explanation:

number = x

sum of number and ten is twenty

so, x +10=20

Answer:

the answer 24 squared

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Add 11 on both sides, therefore getting x is less than or equal to 11.  Now find the graph that fits the description - therefore D.  

There is no picture but I'll help you find out:

The inequality is easy because an inequality says,

y > mx + b (This is just an example)

m = slope

b = y- intercept

What about the sign?

If the circle in the graph which is at the y-intercept (b) is OPEN than it's either < or > depending on where it's going, if it's going to the right on a number line than it's >, however if it goes left than it's <.

What about the AND EQUAL TO sign?

Well same rules apply, however if the circle is CLOSED than it should be      ≤ or ≥, same rules apply, if it goes right or left it's the same rule the only thing that changes is the and equal to, if circle is closed.

Example:

slope: 1/2

y-intercept: -9 (and the line is shaded to the right)

Open circle:

Equation: y > 1/2x - 9

Example 2:

slope: 3/4

y-intercept: -9 (is shaded to the left (less than))

(shaded)Closed circle:

Equation: y ≤ 3/4x - 9

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:

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
