Answer:

there are 24.14 kilometers in 15 miles

Answer:

0-7

Step-by-step explanation:

89-0

Answer: 65 kmh

Step-by-step explanation:

70 kmh for 2 hours = 140 km.

63 kmh for 5 hours = 315 km

140 + 315 = 455/7 total hours = 65 kmh

Step-by-step explanation:

1.The formula in finding the area of a circle is derived from the area of a parallelogram. It is false.

2. The area of a circle is πr² where r is the radius of the circle. It is true.

3. The area of a circle is equal to pi divided by the square of the radius. It is false.

4. The diameter of a circle is equal to twice its radius i.e. d = 2r. It is true.

5. If r = 2.1 m

Area of circle, A =  πr²

= 3.14 (2.1)²

= 13.85 m²

Henc,e this is the required solution.

Answer:

n+6+2n+3+90=180

3n+99=180

3n=81

n=27

33 plus 90+57=180

Answer:

the value of n is 27 degree

Step-by-step explanation:

n+6+2n+3+90=180 degree (being linear pair)

3n+9+90=180

3n=180-99

3n=81

n=81/3

n=27

A linear pair is a pair of adjacent angles formed when two lines intersect.

Answer:

I think is 15 dollars.

Step-by-step explanation:

each pound cost 1.5 multiply it by 10

Answer:

$15

Step-by-step explanation:

4 pounds are $6

10pounds are $?

1 pound would be $1.5, because 6/4 = 3/2= 1.5

If one pound is 1.5 dollars, 10 pounds would be 10*1.5=$15

Answer:

C) 10.63 units.

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

We have the two points (2, -3) and (-6, 4). Let (2, -3) be (x₁, y₁) and let (-6, 4) be (x₂, y₂). Substitute:

[tex]d=\sqrt{(-6-2)^2+(4-(-3))^2}[/tex]

Simplify:

[tex]d=\sqrt{(-8)^2+(7)^2}[/tex]

Evaluate:

[tex]d=\sqrt{64+49}=\sqrt{113}\approx10.63\text{ units}[/tex]

Our answer is C.

Answer:

1.733

Step-by-step explanation:

Given ratio ,

=> 3:2

According to the Question ,

=> $ 2.60 / x = 3/2

=> x = $ 2.60 × 2/3

=> x = $ 1.733

Answer:

≈ $1.73

Step-by-step explanation:

[tex]\frac{2.6}{y} :\frac{3}{2}[/tex]

y × 3 = 2 × 2.6

3y = 5.2

3y ÷ 3 = 5.2 ÷ 3

[tex]y=1\frac{11}{15}[/tex]

y = 1.7333333333333

1.7333333333333 rounds to $1.73

===================================

Explanation:

If we plug the coordinates of point A into the inequality, then we get

x+y > -2

10 + (-1) > -2

9 > -2

That last inequality is a true statement since 9 is to the right of -2 on the number line. That means (10,-1) is a solution. Choice A is one of the answers

Choices B and D are also answers for similar reasons.

Something like choice C is not a solution because

x+y > -2

-1+(-9) > -2

-10 > -2

which is false

You should find that choice E is false as well.

---------------------

If you graphed the inequality and all of the points mentioned (see below), then you can visually confirm the answers. Notice how points A, B and D are in the blue shaded region which is the solution set.

The point E on the boundary does not count as a solution. This is due to the lack of "or equal to" portion of the inequality sign. That visually shows point E is not a solution. Point C isn't a solution either as it's nowhere near the blue shaded region.

Answer:

[tex]P(X = 0) = 0.2[/tex]

[tex]P(X = 1) = 0.2[/tex]

[tex]P(X = 2) = 0.2[/tex]

[tex]P(X = 3) = 0.2[/tex]

[tex]P(X = 4) = 0.2[/tex]

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

pmf of X.

Probability of each outcome, 0, 1, 2, 3 or 4 white balls drawn.

Before the trials, you are equally as likely to get the black ball in the 1st trial(0 white balls drawn) to the 5th trial(4 white balls drawn). So this is an uniform distribution with [tex]P(X = x) = \frac{1}{5} = 0.2[/tex]

Thus, the pmf is:

[tex]P(X = 0) = 0.2[/tex]

[tex]P(X = 1) = 0.2[/tex]

[tex]P(X = 2) = 0.2[/tex]

[tex]P(X = 3) = 0.2[/tex]

[tex]P(X = 4) = 0.2[/tex]

The quotient obtained by dividing 4x²+3x+2 will be 4x + 15 hence option (A) will be correct.

An equation can be defined in numerous ways. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.

A formula known as an equation uses the same sign to denote the equality of two expressions.

In another word, the equation must be constrained with some constraint.

Given that

dividend  =  4x²+3x+2

divider = x -3

⇒ (x - 3) / 4x²+3x+2

⇒ (x - 3) / 4x²+3x+2

→ First it will goes for 4x time so 4x × (x - 3) = 4x² - 12x

Quotient = 4x

so (4x²+3x+2) - (  4x² - 12x ) = 15x + 2

(x - 3) / 4x²+3x+2

→ Second time it goes for 15 so 15 × (x - 3) = 15x -45

Quotient = 15

so  (15x + 2 ) - (  15x -45 ) = 47

Hence, 47 will be the remainder and the quotient will be (4x + 15).

Answer:

y = {0 , 12}, x = -1

point 1     (-1, 0)

point 2    (-1, 12)

Step-by-step explanation:

use the distance formula

d² = (∆x)² + (∆y)²

-----------------------------

10 units away from the point (7,6)

x-cordinate of -1

10² = (-1 - 7)² + (y - 6)²

100 = 64 + (y - 6)²

Subtract 64 from both sides

36 = (y - 6)²

Take the square root of both sides

±6 = y - 6

Add 6 to both sides

y = {0 , 12}

point 1

(-1, 0)

point 2

Answer:

21.77

Step-by-step explanation:

Applying,

V = (4/3)π(R²-r²)³/²................. Equation 1

Where  V = Volume of the resultant shape, R = radius of the sphere, r = radius of the hole bored, π = pie

From the question,

Given: R = 2, r = 1

Constant: π = 3.14

Substitute these values into equation 1

V = 4/3(3.14)(2²-1²)³/²

V = (12.56/3)(3)³/²

V = 4.19(5.196)

V = 21.77

Albert Einstein was a German mathematician and physicist who developed the special and general theories of relativity.

Hi!Albert Einstein, (born March 14, 1879, Ulm, Württemberg, Germany—died April 18, 1955, Princeton, New Jersey, U.S.), German-born physicist who developed the special and general theories of relativity and won the Nobel Prize for Physics in 1921 for his explanation of the photoelectric effect. Einstein is generally considered the most influential physicist of the 20th century.

Answer:

A1 7% = $400 & A2 8% = $16,600

Step-by-step explanation:

A1 * 7% + A2 * 8% = 1356

A1 + A2 = 17000

A1 = 17000 - A2

(17000 - A2) * 0.07 + A2 * 0.08 = 1356

1190 - 0.07 A2 + 0.08 A2 = 1356

1190 + 0.01 A2 = 1356

0.01 A2 = 166

A2 = 16600

A1 = 17000 - A2

A1 = 17000 - 16600

A1 = 400

Answer:

a) This probability as empirical Probability.

b) This probability is not accurate because this experiment must be repeated a large number of times for empirical probabilities should be accurate.

Given the following parameters:

Substitute the given parameters into the formula to have:

9.3/sin109 = 9.6/sin∠H
