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:

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

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:

D but see below.

Step-by-step explanation:

So you have a question that has no clear answer. If Jeff took grade 11 and Lana took grade 12, that would make the answer much clearer. At least there would be no duplicates.

If you could refine the question a little more, you might get a clearer answer. I don't think this question should be asked and I sure don't think you should try and give an answer.

However that's not how schools work. So I would pick D, but by some bizarre method, the asker (like edge) might think of a way to make A B or C true.

Answer:

there are 24.14 kilometers in 15 miles

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

(-1, 12)

Answer:

r=20

Step-by-step explanation:

since the angle and sum of a straight line is equal to 180, you structure an equation:

180=105+(4r-5)

solve for r

180=100+4r

80=4r

20=r

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:

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.

Step-by-step explanation:

On 6 occasions, of which three times the train was late. that means 3 times the train is on time.

Empirical probability = Number of outcomes satisfying event / No.of trails

                                = 3/6 = 0.5.

a) This probability as empirical Probability.

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

Answer: 65 kmh

Step-by-step explanation:

70 kmh for 2 hours = 140 km.

Answer:

2 1/4

Step-by-step explanation:

We have to make the first value into an improper fraction, which makes 3 3/8 into 27/8. Now we subtract 9 from 27, giving us 18. This 18 is still over the common denominator of 8. 8 goes into 18 twice with 2 left over. So we have our mixed number as 2 2/8, which can be simplified to 2 1/4.

Answer:

slope = -5 equation= y=-5x+100

Step-by-step explanation:

pick the x and y intercepts as your points to find the gradient that is

(20,0) and (0,100)

slope =∆y/∆x

=100/-20

= -5

take point(20,0) and (x,y) to find equation using the slope

equation becomes y= -5x+100

Answer:

# of rows: 34

# of seats in each row: 46

Step-by-step explanation:

r - # of rows

s - # of seats in each row

r * s = 1564

s = r + 12

(34) * (46) = 1564

(46) = (34) + 12

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:

32

Step-by-step explanation:

The perimeter is equal to sum of side lengths

10z = 80 divide both sides by 10

z = 8 PR is 4z so 8*4 = 32

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).
