Answer:

26

Step-by-step explanation:

4(7-1) +2

4(6) + 2

24+ 2

26

Answer: 26

Step-by-step explanation:

4(x-y)+2

Lets plug in 7 for x and 1 for y

4(7-1)+2=4(6)+2

4*6=24

24+2=26

26 is the answer

What is diameter:

in geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere.

What is radius:

In classical geometry, a radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.

Explanation:

The diameter is the line that goes across the center of the circle and double the radius which is half, therefore KR is the correct answer.

Answer:

KR, D, or the last option.

Statement answer:

Segment KR is the Diameter of Q.

Answer:

x = 9

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + x² = (9[tex]\sqrt{2}[/tex] )²

2x² = 162 ( divide both sides by 2 )

x² = 81 ( take the square root of both sides )

x = [tex]\sqrt{81}[/tex] = 9

Answer:

22

Step-by-step explanation:

Add al the digits (198) then divide by how many digits there are (9)

198÷9=22

1/6 is the answer because 12 is two times bigger than 6. And the thing that is two times smaller than 2 is 1. That's the quick way of explaining it.

Answer: 1/6=2/12

Step-by-step explanation:

when you multiply something by 1 you get the numbered you multiplied it by so when you multiply [tex]1x2[/tex] you get 2 so you would

[tex]2/12[/tex]÷2=[tex]1/6[/tex]

you divide both numbers by 2 or what ever they are divisible by

Answer:

The radius of circle O is 13.

∠LMP intercepts a semicircle.

LP is a diameter of circle O

Step-by-step explanation:

Find the diagram attached

From the circle, PL is the diameter of the circle;

Also, LMP intercepts a semicircle since the triangle LMP is a triangle in the semicircle of the circle.

According to pythagoras theorem;

ML²+MP² = PL²

24²+10² = PL²

576 + 100 = PL²

676 = PL²

Swap

PL² = 676

PL = √676

PL = 26

Since radius = diameter/2

Radius of the circle = 26/2

Radius of the circle = 13

Hence the radius of circle O is 13.

The sum of the temperatures is S = -2°C

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the temperatures on different days be represented by the table

Now , total temperature is S = -6 + 3 + 4 - 2 - 1

On simplifying the equation , we get

S = -2°C

Hence , the temperature is S = -2°C

hi

if it's intersect, then :  

4x-10 = -4x+8

-10-8 = -4x-4x

 -18  = -8x

 -18/-8 = x

   18/8 = x

   9*2 /4*2 = X

   9/4 = X

So X is  9/4   then y  is  :   4( 9/4) -10 =  9-10 = -1

Answer:

D) 16π/3 ft

Step-by-step explanation:

We solve the above question using the Arc length formula when our central angle is in degrees

The formula is given as:

Arc length = 2πr × θ /360

r = 4 ft

θ = Central angle in degrees = 240°

Hence,

2 × π × 4 × 240/360

8π × 240/360

8π × 20/30

16π/3 ft

Arc length = 16π/3 ft

Option D is the correct option

Answer:

it is B 70° because if you add 40° + 70° = 110°

so then you need to subtract that from 180°.

180° - 110° = 70°

The measure of angle x is 150 degree.

The definition of "supplementary" in mathematics relates to angles that combine to form a straight angle. It indicates that when two angles sum up to 180 degrees, they are said to be supplementary angles.

As, the angle adjacent to 70° angle

= 180- 70

= 110°

Now, the angle supplement to x

x = 180 - (40+ 110)

x = 180 - 150

x = 30

So, the measure of angle x is 150 degree.

Answer:

<B=119

Step-by-step explanation:

Each line of the triangle is straight, meaning they add up to 180. Additionally, all the angles of the triangle add up to 180. Using that, you can find the measure of each angle.

For <C;

180-112=68

So <C=68

For <A;

180-51-68=61

So <A=61

To make sure that all these angles add up correctly;

51+68+61=180

For <B;

180-61=119

So <B=119
