Answer:

Area of circle = 200.96 units²

Step-by-step explanation:

The formula to find the area of a circle is: πr², where r is the radius (which is half of the diameter)

So the diameter is 16 and of 16 is 8, which is the radius.

Sub it into the formula of a circle and you would get the area of a circle.

3.14 x 8²

Use calculator

Area of circle = 200.96 units²

Answer:

if the measure of an angle is 90°, then the angle is a right angle.

Step-by-step explanation:

p=the measure of an angle is 90°

q=the angle is a right angle

p is the hypothesis of the conditional statement

q is the conclusion of the conditional statement

Answer:

100°

Step-by-step explanation:

first you need to find the other angle. to do so do 180-135=45

so you know 2 angles now. 35° and 45°. Add these angles (you get 80°)

then 180-80=100

Answer:

2m / n² - 2n

Step-by-step explanation:

Given that:

Number of friends = n

Weekly rent = $m

To share rent fee equally :

Each friend will pay : $m / n

If 2 of the friend couldn't make the trip:

Additional amount to be shared by the others = 2(m/n) = 2m/n

Hence additional fee per friend who eventually made the trip:

Additional amount to be shared / number of friend who eventually made the trip

= (2m/n) ÷ (n - 2)

= 2m / n * 1 / n - 2

= 2m / n(n-2)

= 2m / n² - 2n

Answer:

Given that x=5, when we substitute in 5 for 2x + 3 = 13, the equation will turn out to be true.

Step-by-step explanation:

2x + 3 = 13       x=5

2(5)+3=13

10+3=13

13=13

2x + 3 = 13

x=5

2(5)+3=13

10+3=13

13=13

Answer:

its D

Step-by-step explanation:

-9(x + 3) + 12 = -3(2x + 5) − 3x

-9x-27+25 = -6x-15-3x

-9x-15 = -9x - 15

same on both sides

so x has infinitely many solutions

The equation has no solutions. Option C is correct.

To figure out which statement is true for equation -9(x + 3) + 12 = -3(2x + 5) − 3x.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
-9(x + 3) + 12 = -3(2x + 5) − 3x.
Simplification,
LHS
= -9(x + 3) + 12

= -9x -21 + 12
= -9x -9

RHS,
=  -3(2x + 5) − 3x
= -6x - 15 - 3x
= -9x - 15
Equation RHS and LHS,
-9x - 15 = -9x -9
-15 = -9
Implies, the value of x terminate means the given expression has no solution,

Thus, the equation has no solutions. Option C is correct.

Answer:

[tex]y=2x-8[/tex]

Step-by-step explanation:

First, remember that perpendicular lines have opposite and reciprocal slopes to the original line. That means for this line, your slope will be 2 (flip the fraction and change the sign). So we have:

[tex]y=2x+b[/tex]

Next, plug in the point that it passes through in order to find the y-intercept (b).

[tex]4=2(6)+b[/tex]

[tex]4=12+b[/tex]

[tex]b=-8[/tex]

So your equation will be:

[tex]y=2x-8[/tex]

Answer:

The smallest possible value of the divisor is 19

Step-by-step explanation:

The given numbers for division are;

3759 and 4139, the remainder = 16

Let x represent the number

Therefore, we have;

x > 16

x is a factor of 3759 - 16 = 3743, and x is also a factor of 4139 - 16 = 4123

The factors of 3743 obtained from an online resource are 1, 19, 197, 3759

The factors of 4123 obtained from an online resource are 1, 7, 19, 31, 133, 217, 589, 4123

The common factors of 3743 and 4123 are 1, 19

Given that x > 16, we have, x = 19

Therefore, the smallest possible value that will divide both 3759 and 4139 whereby the remainder is 16 = 19

Answer:

Step-by-step explanation:

Given

m∠COD=8x+13,

m∠BOC=3x-10, and

m∠BOD=12x-6

The following addition property is true;

<BOD = <BOC + <COD

Substitute

12x-6 = 3x-10+8x+13

12x-6 = 11x+3

12x-11x = 3+6

x = 9

Get <BOD

<BOD = 12x-6

<BOD = 12(9)-6

<BOD = 108-6

<BOD = 102°

Step-by-step explanation:

While graphing inequalities, think of the inequality sign as an equal sign.

So, y=mx+b.

Say the inequality was y>3x+7, I would think fo the > as an equal sign.

So, in your head, "write" it like this: y=3x+7. Hope this helps.
