Which expression is equivalent to 8 (n − 2)
A 8n – 2
B) 2n – 8
C 16n
D) 8n – 16

Answer:

What is the radius?

Step-by-step explanation:

Answer:

x = 20°

Step-by-step explanation:

here's your solution

=> it is given that whole angle is 90°

=> so, x + (3x + 10) = 90°

=> x + 3x + 10 = 90°

=> 4x + 10 = 90°

=>4x = 90 - 10

=> 4x = 80°

=.

=> x = 80/4

=> x = 20°

one angle is 20° and other 70°

hope it helps

Answer:

20 is your answer

x+3x+10=90 being right angle

4x=90-10

x=80/4=20

Step-by-step explanation:

Answer:

x = 3.38

y = 9.24

z = 8

Step-by-step explanation:

first: solve for the vertical length

8√2² = 2z²

128 = 2z²

z² = 64

z = 8

vertical height = 8 also because z is one side of a square

tan 60 = z/a = 8/a

a = 4.62

x = 8 - 4.62 = 3.38

sin 60 = z/y = 8/y

y = 9.24

10/38 is what i think it is

Answer:

10.

Step-by-step explanation:

Lets define a square root.  A square root is a number multiplied by itself.        10 x 10 = 100, this is the closest we can get to 105, therefore 10 is the answer.

Answer:

radius can't be found of a number. radius is used for geometry. If it is the area of circle, soln is below

Step-by-step explanation:

πr²= 484

r² = 484×7/22

r²=22×7

r = √154

Step-by-step explanation:

the three rational numbers equivalent to each of the following rational number:-

i) -2/5=-4/10,-6/15 and -8/20.

ii) 3/7=6/14,9/21_and 13/28

Answer:

2/3

Step-by-step explanation:

First, we read the two points with circles off the graph.

They are (-4, -5) and (5, 1).

slope = (y2 - y1)/(x2 - x1) = (-5 - 1)/(-4 - 5) = -6/(-9) = 2/3

Answer: 2/3

Answer:

A. Add -2 to both sides

Step-by-step explanation:

The reason you need to add -2 to both sides is because if you add -2 to -2 it cancels out and you are left with x=18. But you need to add -2 to 18 too because them the equation won't be equal anymore.

Answer:

[tex]10 \sqrt{3} [/tex]

Step-by-step explanation:

To find the value of x.

According to Pythagoras Theorem-

[tex] {20}^{2} = {10}^{2} + {x}^{2} [/tex]

[tex] = > 100 + {x}^{2} = 400[/tex]

[tex] = > {x}^{2} = 400 - 100[/tex]

[tex] = > {x}^{2} = 300[/tex]

[tex] = > x = \sqrt{300} [/tex]

[tex] = > x = 10 \sqrt{3} [/tex]

Hence, the required value of x is

[tex] 10\sqrt{3} [/tex]

Answer:

(-3, -4)

Step-by-step explanation:

y= -4

so you plus y in for the y=2x+2 equation where you get x=-3

[tex]\huge\text{Hey there!}[/tex]

[tex]\large\text{If y = -4 then SUBSTITUTE it into the EQUATION}[/tex]

[tex]\large\text{-4 = 2x + 2}[/tex]

[tex]\large\text{TURN the EQUATION}[/tex]

[tex]\large\text{2x + 2 = -4}[/tex]

[tex]\large\text{SUBTRACT by 2 to BOTH SIDES}[/tex]

[tex]\large\text{2x + 2 - 2 = -4 - 2}[/tex]

[tex]\large\text{CANCEL out: 2 - 2 because that gives you 0}[/tex]

[tex]\large\text{Keep: -4 - 2 because it helps us solve for x}[/tex]

[tex]\large\text{2x = -6}[/tex]

[tex]\large\text{DIVIDE by 2 to BOTH SIDES }[/tex]

[tex]\mathsf{\dfrac{2x}{2}=\dfrac{-6}{2}}[/tex]

[tex]\large\text{CANCEL out: }\mathsf{\dfrac{2}{2}}[/tex] [tex]\large\text{because that gives you 1}[/tex]

[tex]\large\text{KEEP: }\mathsf{\dfrac{-6}{2}}[/tex]  [tex]\large\text{because it gives us the value of x }[/tex]

Answer:

1) 4 hours  2) 144 miles  3) 12 miles

Step-by-step explanation:

60/5=12

72/6=12

120/10=12

180/15= 12

1) 48 miles / 12 miles = 4 hours

2) 12 hours x 12 miles = 144 miles

3) 1 hour x 12 miles = 12 miles

Answer:

This quadratic has two unequal, imaginary roots.

Step-by-step explanation:

y = 3x^2 + 8 is a quadratic function, and (like all quadratics) it has two roots.  In this case they happen to be different (unequal), as well as imaginary.

Setting y = 3x^2 + 8 = 0, we get:

3x^2 = -8, or

x^2 = -8/3

Taking the square root of both sides, we get

x = ±i√(8/3) (2 imaginary roots)

Answer:

cos A = 53.13

Step-by-step explanation:

cos = [tex]\frac{adajacent}{hypotenuse}[/tex]

cos A = [tex]\frac{12}{20}[/tex]

cos A = 0.60

cos-1 0.60 = A

53.13 = A

Given:

Base of the triangle = 24

Height of the triangle = 10

Another side of the triangle = 26

To find:

The area of the expression of the area of the triangle.

Solution:

We know that, the area of a triangle is

[tex]Area=\dfrac{1}{2}\times base\times height[/tex]

Putting base = 24 and height = 10, we get

[tex]Area=\dfrac{1}{2}\times 24\times 10[/tex]

It can be written as

[tex]Area=\dfrac{1}{2}\times 10\times 24[/tex]

Therefore, the correct option is A.

Answer:

The correct answer is A.

One-half times 10 times 24

Answer:

68.5 feet per minute

Step-by-step explanation:

rate of descent = feet / minute

First you need to find how many feet it has descended:

beginning altitude- ending altitude = total feet descended

5717 feet - 3388 feet = 2329 feet

To figure out the rate of decent we will divide

2329 feet / 34 minutes = 68.5 feet per minute

The hot air ballon descended 68.5 feet per minute for 34 minutes.

Answer: 16,17,18

Step-by-step explanation:

(x)+(x+1)+(x+2) = 51

x+x+x+1+2=51

3x+3=51

3x=51-3

3x=48

x=16

x+1 = 17

x+2= 18

Let, the three consecutive integers be x, x+1 and x+2.
